Everything about the meat grinder - operating principle, device diagram, procedure for use. How to choose a meat grinder for your home - expert advice Design of a mechanical meat grinder

Fans of preparing homemade food often think about choosing the right electric meat grinder, since they no longer want to eat store-bought semi-finished products, and sometimes it is harmful to health. Electric meat grinders are devices capable of grinding meat. They are usually used for making meat dishes, sausages and minced meat. For cast iron manual meat grinders, the design of which is for a long time has not changed, everyone got used to it. And devices such as electric meat grinders are not very familiar to many people, since they appeared in everyday life relatively recently.

The electric meat grinder has more complex device, compared to the mechanical one, but its functions remained similar. Such devices make our everyday life much easier. If a manual meat grinder can grind as much meat as the housewife can, then with the help of a modern electric meat grinder you can process up to three kilograms of meat in one minute. Any type of meat is suitable for twisting: beef, pork, chicken, etc. The housewife only needs to feed pieces of meat into the upper funnel, and the meat grinder will do the rest itself.

How do electric meat grinders work?

Unlike manual mechanical ones, electric meat grinders are more attractive in appearance and have significantly more functions. They are easy to use and do not require much physical effort to operate. The cost of such devices depends on the manufacturer, power and number of auxiliary functions. Using such an electric meat grinder except minced meat You can make juice, noodles, cookie dough, and chop fruits and vegetables using the included attachments.

The design of an electric meat grinder is quite simple, and differs from a conventional manual meat grinder only in the presence of an electric drive and several functional attachments.

The electric meat grinder includes:

• Electric mechanism activates the meat grinder.
• Frame working mechanism, made of cast iron, of stainless steel or aluminum alloys.
• Receiver in the form of a tray for storing meat.
• Screw, serves pieces of meat for chopping.
• Knife, usually having four cutting blades. There are also two-blade knives.
• Lattice made in the form steel disk with holes for meat to come out. It is also called the matrix.
• Pressure nut , fixes the internal parts of the device.

Principle of operation

Meat cut into pieces in advance is placed on top of the receiving tray. Once on the turns of the auger, the meat moves to the knife, which is mounted on the front end of the auger. The rear part of the auger (shank) is connected to an electric drive.

The knife rotates along with the auger, fitting tightly to the grate, which is fixed motionless. Due to this, the meat is cut with a knife, chopped and pushed through the holes of the grate using an auger. Additional pressure to push the meat is created by feeding subsequent portions of meat.

IN electric drive the engine is located inside the housing and is started using a button. There are rubber feet at the bottom of the case, the use of which allows you to:

• Reduce vibration loads during operation of the electric meat grinder.
• Reduce the level of electrostatic charge in the device body.
• Prevent the meat grinder from moving or sliding during operation.

Types of electric meat grinders

IN trading network for sale household appliances There are many types of electric meat grinders, differing in size, cost, functionality and other characteristics. Let's look at some of the main types of electric meat grinders to have an idea about them and make right choice quality and reliable product.

According to the principle of meat processing:

• Shnekovs e. In such designs, the meat is chopped with a knife and moved to it by rotating the auger.
• Cutter. Such devices in household Rarely used, they are usually included in a mixer or food processor. The meat in them is ground in a special container with knives rotating at high speed, similar to the principle of operation of a blender. At the same time, the meat is strongly beaten and saturated with air. As a result, the minced meat turns out to be a paste, which many people do not like. Such meat grinders are most often purchased by lovers of ground boiled foods, or for preparing dietary food or baby food.

By functionality:

• Traditional Electric meat grinders are designed for grinding meat only. They do not have any auxiliary functions. Such meat grinders can process a large volume of meat in a short time. They are similar in functionality to manual mechanical meat grinders.
• Universal Electric meat grinders come with all kinds of attachments: for pasta, grinding and slicing vegetables, squeezing juice, etc. Due to their great functionality, their power is low.
• Food processors are the dream of many housewives. They grind food into puree form, which is not entirely suitable for many dishes. Such designs have little power and low productivity. Their weak knives do not always cope with tough types of meat, so it is better to use traditional types meat grinder

Electric meat grinders are divided into three classes based on performance:

• "A" — upper class and high performance. Their main task is to grind meat different varieties for preparing minced meat.
• "IN"— this class includes household multifunctional meat grinders of medium productivity with a set of additional knives, graters and various attachments.
• "WITH"- simple household ones with minimal power, without additional functions and modes.

Parameters of electric meat grinders

When choosing household devices, including electric meat grinders, you should take them into account technical specifications, the main ones of which we will consider in more detail.

Power

For many electrical devices this parameter is the main selection criterion. The higher the power of the device, the greater its performance. There are models of meat grinders with power from 0.4 to 2.2 kilowatts. It is very rare to find a 3 kW model. High power ensures high-quality chopping of meat, preventing the knives from clogging with meat veins, which are difficult to grind.

• Low-power meat grinders up to 0.8 kilowatts can cope with non-tough meat without veins. They are also suitable for fish and vegetables and are inexpensive. If the meat is cut into small pieces, the performance of the device will increase significantly.
• Meat grinders with a power of no more than 1.4 kW can cope with any type of meat, resulting in excellent quality minced meat.
• Powerful electric meat grinders above 1.5 kilowatts can quickly process large volumes of meat. The cost of such products is quite high. According to their power, such meat grinders consume a lot of electricity and also have increased operating noise, unlike low-power designs. Therefore for home use they are practically never purchased.

Materials

An important parameter for choosing a device is the materials used to make its elements. The tray and body must be made of food-grade plastic, and the remaining elements must be made of metal. The pusher must be made of food-grade plastic.

The most important part is the auger, which has a spiral shape, with attachments for the knife and attachments. The auger should be made of durable stainless steel, as should the knives, which do not need frequent sharpening.

Electric motor and operating noise

Many manufacturers supply their products special system interlock that stops the electric motor in the event of a heavy load, preventing it from breaking down due to overheating.

The noise level of an electric meat grinder depends on the power; the higher the power, the more noise it creates during operation. There are models of significant power, but with low noise levels. When choosing a device, it is advisable to pay attention to this and ask the seller to include several types of products in order to understand how much noise there will be when processing meat in an apartment. In addition, you will become familiar with the correct way to launch it. You should also know that electric meat grinders are much louder compared to a food processor.

Lattices

The optimal choice would be an electric meat grinder with a set of interchangeable grates that differ in the diameter of the holes for obtaining small, medium and large minced meat. The thickness of the grid may also vary; a grid that is too thin can negatively affect the quality of the minced meat.

Knives

The main working element is knives, which can have a different number of edges. The set may contain two knives. They are usually made of durable stainless steel, but also require periodic sharpening. Some expensive electric meat grinders are equipped with self-sharpening knives. They do not become dull even after prolonged use.

Nozzles

These elements increase the functionality of the meat grinder. Using attachments you can cut and chop vegetables into pieces different sizes. There are nozzles for preparing sausages and wieners; they are made in the form of a metal cone. If you remove the knife and grate and install a special disk, you can make pasta and noodles. There is even an attachment that can be used to crush ice.

Additional functions

• Motor protection from overload is installed on many types of meat grinders. At increased load more permissible value, turns off automatically. Gear drives often have plastic bushings installed, which break under heavy loads. There are also devices that de-energize the entire device when it is heated to a temperature above the established norm.
• Reverse. This function ensures that the auger moves in the opposite direction. It often happens that a lot of wires are wound on the auger, and further work becomes impossible. At the same time, reverse is turned on and the auger is freely cleaned to continue normal operation.

Classification of electric meat grinders

Modern industry produces two types of electric meat grinders:

Screw

Table 2 - Characteristics of meat grinders

The physical principle of operation of an electric meat grinder

The working body of a screw electric meat grinder (EMM) is identical to a conventional manual meat grinder, but the screw receives its rotational movement from an electric drive. When rotating, the auger captures the processed product, which is fed into the loading neck of the housing, and moves it to the cutting device - a knife mounted on the auger and a grate.

The product pressed into the holes of the grate is cut off by a rotating four-bladed knife that fits tightly to the end of the grate. Under the pressure of subsequent portions of the product, which are continuously transported by the screw, the crushed product is squeezed out of the grate holes in the form of minced meat.

In the Cutter Electric Meat Grinder (EMC), the chopping (grinding) of the product occurs by chopping it with sickle-shaped lamellar knives directed in opposite directions. Rotational movement At high frequencies (over 8000 rpm), sickle-shaped knives are produced from an electric motor on the shaft of which they are mounted.

Main quality indicators of electric meat grinders

What you should immediately pay attention to when choosing an electric meat grinder is its power; it is the main indicator of the capabilities of an electric meat grinder, because if the power is not enough, the machine will become completely useless in the kitchen. An excellent power indicator is a value of 800 W, the optimal is 500-600 W, however, there are mini models with a power of 200-400 W. Second important parameter when choosing, the material from which the device is made. In general, there is nothing wrong when special food-grade plastic is used for this, which can withstand the loads transmitted to the body.

Internal parts such as grates, knives, and auger must be made of metal, since they bear all the loads during operation of the device. The auger is the main part of the spiral shape; nozzles and knives are attached to it. When rotating, the auger also moves the meat from the inlet neck to the outlet of the device. It happens that electric meat grinders have two screws: plastic for fruits and berries and metal for meat, for example the Tefal ME7011 model. A meat grinder, the body of which is entirely made of metal, will be more stable, but will also increase its weight.

No less important details What the auger is, are the knives. Knives must be made of good steel; they can also be sharpened periodically, and the frequency of this process will depend on the quality of the steel. However, there are models of meat grinders that do not need to sharpen knives; they are either made of high-quality steel or are self-sharpening.

Reverse or reverse scrolling, that is, rotating the auger in the opposite direction. It is used in cases where you have a stuck core, then using reverse the auger will return it to the inlet hole. If the electric meat grinder does not have such a function, then you will have to do it all manually, disassembling the device.

Motor protection may take the form of a circuit breaker or electrical fuse, or a mechanical interlock. However, both types of protection are designed to protect the motor from overloads and overheating.

Another indicator of the quality of electric meat grinders is the gearbox. To reduce the cost of construction, plastic gears have recently been used in gearboxes; they are less reliable than metal ones and are suitable where there are no heavy loads, or the service life of the device becomes 2 times less. Fortunately, imported manufacturers offer assembled gearboxes that can be replaced at home or in a special workshop for repairing household appliances.

There are three holes in the body, by looking at which you can answer the question of how to assemble a manual meat grinder.

1. Meat receiver, where is he going loading of products required processing.
2. The rear large exit of the auger shaft is intended for a handle that will rotate it. To ensure that it sits firmly, manufacturers can equip the meat grinder with a special nut. Some housewives remove it because it interferes with their work. Therefore, it is sometimes missing on old meat grinders.
3. The front outlet is for the thin end of the shaft on which the knife and mesh are attached.

At the bottom of the housing is equipped with a special device, with the help of which the unit is tightly attached to kitchen table for work.

What is included in the set of kitchen unit parts:

1. The screw shaft is a large spiral necessary for delivering processed products to the knife.
2. A knife in the form of a disk or a four-wing propeller, properly positioned, is capable of grinding many products.
3. Grate – a flat disk with big amount holes, which determines how well the final product will be crushed.
4. A clamping nut that is screwed on top and secures the grid and knife to the shaft.
5. Handle attached on the opposite side. It can be freely installed on the outgoing end of the screw shaft or attached to it with a special screw.

Having dealt with all the details, you can learn how to assemble a manual meat grinder.

How to assemble all the parts correctly

At the beginning of the assembly, housewives collect all the parts from the meat grinder and arrange them on the table near them. First, they pick up the all-metal housing and insert the screw shaft into it so that its thick edge comes out from behind into a narrow hole. A handle will be attached to it. If there is a nut for securing the handle, it must be installed immediately, tightened firmly with a screw. If there is no fastening, the handle is attached last.

The thin side of the auger fits into a wide round hole. It is long enough, and two parts are held on it. First, put on a knife. Installing this part of the meat grinder is the most important point in this whole process. The knife must be installed correctly, otherwise it will not work.

On one side, the meat grinder knife has flat wings, on the other they are convex. The flat side should be on the front side of the meat grinder and clearly visible, and the convex side should remain inside near the auger.

The disc-shaped knife is installed so that its cutting edges are on the outside.

It is important to preserve the knives that came with this particular unit, because parts from another manufacturer may not fit the structure of the all-metal body, and the process of chopping products will be disrupted.

A meat grinder is a mechanical household appliance made of metal or its alloys for processing various food products. The manual version has long been outdated and has been replaced by modern and powerful electric models. The design of a new type of meat grinder and the principle of its operation is the topic that we will cover in this article.

Before thoroughly understanding the structure of an electric meat grinder, we will list its advantages over another household appliances, in particular, its mechanical progenitor.

1. An electric meat grinder is more powerful than any food processor in a similar mode, not to mention the muscular strength of an ordinary person.
2. An electric meat grinder will grind any product faster than a human can do it. manual version products save time and effort.
3. The electrical appliance copes well with stringy meat- there is no need to constantly unwind the product, clean the knife and reassemble it.
4. A meat grinder with an electric motor can work on any flat surface without additional mounting.
5. Work safety with them, a narrower neck is provided with sufficient length so that fingers cannot reach the auger. The kit includes a special plastic pusher.

Design

A modern electric meat grinder is equipped with the following basic parts and components:

1. a device made of durable plastic for pushing products inside the device;
2. tray or bowl;
3. metal alloy meat grinder body;
4. drive by electric motor;
5. gearbox;

17. ground clamp.

The schematic diagram of a meat grinder shown in the figure is arbitrary - device different models electric meat grinder has its own nuances, but the main components are the same for all.

The body of the meat receiver, where the products are processed, consists of similar parts as the manual version:

• metal case;
• receiver and tray or bowl;
• screw shaft;
• lattice;
• fixation nut.

Depending on the model, the main parts may include:

• gratings with holes of different diameters;
• additional knives;
• original attachments or graters for processing vegetables and fruits;
• devices for forming dough;
• conical attachment for making homemade sausages, frankfurters and sausages.

All of the above parts are the working parts of the meat grinder. For housewives to visually familiarize themselves with the configuration and purpose of various additional devices, there is a video using the example of the Belarusian electric meat grinder KEM 36 “Assistant”:

Classification of electric meat grinders

Presented on the shelves of hardware stores huge assortment meat grinder Everyone will find a device that suits their budget and the required functionality. To choose best option, you need to imagine what parameters are key for this type of technology, what types there are and how they differ.

According to the operating principle

Screw meat grinders- This traditional version device that is most often used in everyday life. The meat is moved using a screw shaft (auger) to the knives, where it is chopped. The “grain” size is formed by the gratings at the outlet.

Cutter meat grinders They work on the principle of a blender: they chop meat with knives rotating at high speed, which diverge like rays from the shaft to the periphery. The consistency of the meat is ground into porridge and is more suitable for making sausages than cutlets. This option is suitable for those who often prepare homemade sausage, dietary meat dishes or baby food. In household meat grinders, this principle is almost never used. Only in 2 in 1 equipment versions (where a meat grinder is an additional option in kitchen machine or mixer).

According to technical capabilities

The usual version of a meat grinder is in mono version, when the device contains only one option. This is done either to reduce the cost of equipment or to increase its productivity.
Multifunctional devices equipped with devices and attachments for chopping vegetables, making molded products (meat sausages or kurabye cookies from dough), and a built-in juicer.

Harvesters are universal kitchen helpers. They can do many operations with products, including processing meat into minced meat.

Important! Few combines are equipped with a meat grinder attachment in the classical sense. Most often, this option is included in a blender, which grinds the meat into a pulp or chops it into fairly large pieces. Unlike a meat grinder, such devices cannot cope with tough pieces of meat and films.

By power

Based on performance, devices are divided into three categories.

1. Class A has high performance and can be used on small production. In everyday life, such devices can almost instantly grind several kilograms of meat of any quality.
2. Class B- These are good household meat grinders, often multifunctional. Their power is sufficient for home use.
3. Class C- These are the simplest meat grinders without advanced functionality. Basically, these are devices from the lower price category.

What to look for when choosing a meat grinder

The choice of meat grinders is so rich that everyone will find a suitable device. Focusing on technical specifications and quality indicators, you can buy equipment with the best price-quality ratio.

The reference characteristic from which, in principle, one must build, is the power of the device. The rated power of household meat grinders lies in the range of 150-1500 Watts, the performance of the device directly depends on this indicator. Productivity calculates the weight of meat that can be processed in 1 minute. Equipment with good power works not only quickly, but also effectively, coping with tough meat, tendons and films.

Advice! For a home, 1-1.5 kW is enough. It is important to understand that the more powerful the device, the louder it operates.

The materials from which the device is made must be of high quality. Those parts that come into contact with food must be made of plastic, metal and rubber suitable for food production. Power parts that work in motion and under force, such as knives and augers, are best chosen from corrosion resistant metal, and not soft brands, but with good characteristics. A device made from suitable materials, will last much longer.

In addition, the following options will be useful.

1. Presence of reverse (reverse) will avoid extra work: the tendons wound around the auger can be removed thanks to this option without disassembling the entire device.
2. Operating power selection will allow you to adjust the operating mode of the meat grinder depending on the situation. For example, tender chicken breast you can twist it at minimum power, achieving the desired result, while energy consumption will also be minimal.
3. Security Options. IN simple models A fuse is installed that will prevent the device from working if it overheats. More advanced models of meat grinders are equipped with automatic equipment that turns off the device before overload, protecting it. These options will help you avoid emergency situations and extend the life of the device.
4. Additional options. Included with some devices goes whole an arsenal of attachments and accessories that significantly expands the capabilities of the device. Thus, some meat grinders can chop, grind, shape, and squeeze juice from fleshy fruits and citrus fruits.

Adaptations

Many models of electric meat grinders are equipped with additional attachments and devices that help squeeze juice, chop vegetables, make homemade pasta, original-shaped cookies from shortcrust pastry or deli meats in the form of sausages or sausages.

For squeezing juice

Almost any model of a modern electric meat grinder is equipped with devices for producing juice, the only difference is in their location:

• the auger squeezes out the juice along with the pulp through grille with large holes;
• the auger rotates inside graters cylindrical , and almost the entire vegetable or fruit is ground into juice.

For shredding

The meat grinder can replace food processor , which is good for cutting vegetable salads when you are expecting guests, while a lot of the product remains inside the product. When you need to prepare the same thing, but in smaller quantities, the electric assistant will handle it.

There are special attachments for shredding; you can quickly and efficiently prepare vegetables for salad for the whole family, saving time and effort.

For sausages

What man would refuse homemade aromatic sausage with pepper and finely chopped lard? To do this, you don’t need to go to the market or run to the nearest supermarket - do everything at home with your own hands using a special one.

For cookies

Homemade cookies various shapes can be done using an electric meat grinder, for this there is special devices, and everyone has a dough recipe experienced housewife. Delight the whole family and guests with original shaped pastries that you can’t buy in a store.

Operating rules

Before you start processing meat or other product, you need to cut it into pieces so that they pass freely through the cylindrical part of the receiver.

The pusher is used to push the product towards the auger, which moves it towards the cutting tool.

Attention! It is necessary to cut out large veins from the meat, in this way you will protect the electric motor of the meat grinder from excessive load, and the knife from rapid dulling. The auger of any meat grinder has special ribs that direct the product to the outlet, grinding it as it moves. This process, like the actions of the knife, occurs continuously: new portions placed in the meat receiver squeeze the already ground product through the grate into a container placed at the neck. By using electric models easy to make delicate pates: grinding is done several times, passing the finished product through more fine mesh

and adding the necessary ingredients. In order for the meat grinder to work efficiently and the product to function for as long as possible, it is necessary to strictly follow the manufacturer’s recommendations and simple rules

1. operation.
2. Check the meat carefully when cutting it into portioned pieces to put into the receiver; if a small bone gets in, it will cause the knife to break.
3. The knife in the product should always be sharp - this facilitates the rapid processing of any product.
4. Immediately after use, the product must be disassembled, all parts must be washed thoroughly, and after drying, put into a storage box. Before assembling the shaft, knife and grid on the side where the knife is adjacent, experts advise rub with sunflower oil - this will provide best walkthrough products inside the meat grinder and quality work

rubbing parts.

Never store the body of the product, where the main grinding takes place, assembled; remember that in a free state, all parts oxidize less, and their assembly does not take much time.

As you can see, the design of an electric meat grinder and the principle of its operation are extremely simple, but it has many advantages, because with the help of simple attachments you can prepare original homemade delicacies, aromatic dough products and many other delicious dishes. Currently, in addition to household electrical appliances, there are designs for sale: industrial type

The process of grinding ingredients using manual meat grinders requires the use of physical force. That is why the device should first be attached to the table surface with special suction cups or clamps. In this case, the use of devices electric type allows you to automatically perform a similar procedure in a shorter period of time.

Design of the “grinding” device

Today on sale in specialized stores a wide range of meat grinder However, regardless of the diversity model range, the design of such technology is quite simple.

Classical manual meat grinder consists of the following elements:

• - meat receiver located in the upper part household appliance, intended for laying ingredients subject to processing;
• - a screw shaft, thanks to which the raw materials are moved;
• - a cross-shaped knife that chops food;
• - round grille with holes;
• - fastening ring;
• - handles with a screw for attaching the device to the table surface;
• - handles.

As a rule, an electric meat grinder consists of similar elements as a mechanical unit. However, the body of such models often lacks a clamp and a special handle. At the same time, the device is additionally equipped with an electric motor, and the opening for receiving raw materials is equipped with a funnel with a pusher.

IN standard equipment Meat grinders usually include the following attachments:

• - for chopping vegetables and fruits;
• - grater-slicer, for chopping food into shapes;
• - “Kebbe” element, which allows you to create a hollow base for stuffing;
• - press for the production of vegetable, fruit and fruit juices;
• - for preparing sausages;
• - modeling diffuser, which ensures portion distribution of minced meat;
• - for preparing tomato dishes;
• - a dough hook that allows you to make noodles and cookies.

Remember, before using a mechanical or electronic meat grinder, the raw materials should first be cut into small pieces. Following this recommendation will help significantly speed up the cooking process.

Stages of assembling a manual meat grinder

The principle of operation of the meat grinder is based on the passage of the ingredients placed into the bowl through the component parts of the device.

As a rule, raw materials are fed through a meat receiver onto a screw shaft, which presses it against the grate and then cuts it off using a special knife. Thanks to this, a continuous process of grinding food occurs. Remember for efficient work device, it is important to correctly assemble all elements of kitchen equipment.

Algorithm for assembling a mechanical meat grinder

Install the auger shaft. To do this, this element should be placed in a special hole on the device body. Then, on outer rod put on the handle and secure it with a special screw. Before assembling such a device, a small amount of vegetable oil should be applied to the area where the shaft contacts the body.

Secure the knife. To do this, the cutting element should be installed on the screw shaft: with the convex side inside the housing, and the flat side out.

Remember, the efficiency of the chopping device directly depends on the correct installation of the blade.

Place grid. This item can be fixed to the rod on either side. In this case, you should align the cut on the mesh and the protrusion on the body of the device, and then secure the resulting structure using a special ring.

Lock the handle. To securely attach the handle to the back of the device, tighten the thread. At the same time, the ring should not cover the mesh too tightly. Otherwise, the level of wear resistance of knives and grates is reduced.

After assembling the mechanical structure to bring it into working condition, it is necessary to secure the unit to work surface table using a clamp or suction cups.

Assembly sequence of an electric meat grinder

Currently, automated grinding devices make it possible to obtain finer ground food than when cutting products. For this purpose, electrical devices are often additionally equipped with special attachments, namely: double-sided knives, grilles with a set of holes various diameters, special rings and cutting blades.

Remember the order of assembly electrical appliance differs slightly from the assembly of a mechanical analogue.

As a rule, the instructions supplied with the device contain a detailed plan diagram that allows you to correctly install additional elements designs for the selected unit.

The assembly sequence of an electric meat grinder is as follows:

• - insert the screw shaft into the device body;
• - put on a ring equipped with holes large diameter, on the rod;
• - install the double-sided knife on the shaft;
• - put a grid equipped with gaps of medium diameter onto the auger;
• - attach the second knife to the rod;
• - install a mesh equipped with small holes;
• - secure the mechanism with a ring nut;
• - connect the resulting structure to the drive;
• - install the removable bowl on the meat grinder body;
• - connect the device to the power supply.

Remember, regardless of the type of food processing, the flat side of the knives should always be against the mesh.

In some meat grinder models, due to the presence of additional functions, the assembly process may differ significantly. For example, to prepare cookies, instead of a standard grill, a special ring is used, which is equipped with shaped slots. At the same time, there is no need for a cross-shaped knife in the design. As a rule, instead of a cutting element, a persistent metal ring is inserted into the body of the device.

Frequent malfunctions

As a result of intensive use of a meat grinder, sooner or later malfunctions occur during the operation of the device. At the same time, in order to troubleshoot problems, it is important to identify the cause of their occurrence in advance.

Let's look at the most common problems

The meat grinder does not grind meat. At the same time, the raw material placed in the bowl becomes jammed. As a rule, such a malfunction occurs due to incorrect adjustment of the pressure nut.

To eliminate this problem, turn off the electric motor, remove the knives, grates, screw shaft, and then clean structural elements tendon devices. After this, the device must be reassembled by adjusting the degree of tightening of the fastening fittings.

High noise level in the gearbox. This problem, often accompanied by stopping the electric motor. The cause of an unpleasant breakdown is excessive tightening of the pressure nut. To eliminate the problem, loosen the tightening of this fastener.

Winding tendons around the cutting organ of the device. At the same time, the crushed food products are heated. As a rule, such a nuisance occurs due to dull knives or holes in the grill of the device. Sharpening or grinding the cutting elements of the device will help eliminate the problem.
