Manual meat grinder. The main parts in a meat grinder and their purpose. Basic rules of use

Elena 0

One of the most important parameters of an automatic electric meat grinder, which determines how effectively it will cope with its work, is its power. Many manufacturers indicate in the characteristics of their device only maximum power meat grinder (when the shaft is blocked), which is achieved if, for example, there is a bone in the meat, grinding which requires much more high power than for regular meat. In maximum power mode, the meat grinder can operate for no more than 1 minute. Indicators max. powers can vary from 1000 to 2000 watts. In normal mode, the meat grinder operates with rated power, which varies depending on the model from 330 to 1400 W. The higher the power of the meat grinder, the higher its productivity, on the one hand, and the higher the energy consumption, on the other. We should not forget that no matter what the power rating, an electric meat grinder cannot operate for more than 10-15 minutes without a break.

Meat grinder performance- this is the amount of meat that a meat grinder can process in 1 minute. Typically, the performance is indicated in the characteristics of the device (the performance indicator can vary from 1 to 2.5 kg/min)

Some important functions of a meat grinder

Next, you need to understand the design of the meat grinder in order to understand what some of the indicators indicated by the manufacturer in the specifications mean. Below are the main functions of meat grinders, which are often mentioned in the characteristics of the device:

Function "auto reverse"(reverse system) avoids the problem of winding the core on the auger. You don't have to pick out a stuck vein with a fork or disassemble the meat grinder. To remove it, you need to turn off the engine and hold down the “auto reverse” button, after which the auger will begin to rotate in the opposite direction, and the stuck bone or vein will come out. This function is not available on all models of meat grinders, and more powerful models (with a rated power of 1200-1400 W) do not need it, since they, as a rule, do not encounter such problems.

Motor protection against overload, overheating and burnout can be done in two ways: through an automatic circuit breaker (1) or by blocking the motor (2).

(1) During normal operation, the two built-in bimetallic strips are in the closed state. When a bone hits, the flow of incoming electricity increases, the automatic circuit breaker opens the plates, and the motor continues to idle. When the device is turned off, the plates return to their original state.
(2) The method of preventing overload by blocking the engine is less perfect, since when hard parts get into the meat grinder, the plastic connection of the auger and gearbox bursts, the plastic teeth rotate, becoming unusable, but the engine remains intact. As a rule, such meat grinders are produced complete with spare parts provided specifically for such cases.

Meat grinder parts

Knurled nut- this is the part that secures the knives and attachments of the meat grinder. It is screwed to the thread of the hole at the outlet of the meat grinder. The knurled nut may become severely tightened during operation under the influence of centrifugal force. In order to facilitate its removal, some models of meat grinders are equipped with a special wrench for the knurled nut. And in some cases, on the outer rim of the knurled nut there are holes or recesses into which you can insert an object, such as a pencil, and easily unscrew the tightly tightened nut.

Trey- a tray with a hole connected to the neck of the meat grinder into which products are loaded. Can be made of either plastic or metal. A metal tray is considered much better than a plastic one, since it does not lose color, does not get dirty as much, has much higher strength, and is easier to clean. Shape and dimensions of trays different models meat grinders vary. It is believed that the larger the tray, the better.

Pusher - a plastic part that ensures the safety and convenience of pushing food into the meat grinder.

Meat grinder attachments

It is also important to have an idea of what types of meat grinder attachments there are, so that when you come to the store, you buy a meat grinder already knowing which attachments you need.

Perforated disk for minced meat ( sometimes they are called “fixed mesh knives” or “grids”) There are 3 types of disks - with small holes (3-3.5 mm), medium (4-6 mm) and large holes (7-9 mm). The meat grinder kit may contain from 1 to 3 such discs with holes of different diameters.

Perforated discs with blade

Kebbe attachment(“Kubbe”, sausage attachment) is designed for preparing hollow sausages, which can then be stuffed and fried. Some meat grinders are equipped with a special kebbe recipe book for preparing various delicacies.

Cutlet mold (forming attachment)- an accessory that allows you to form ready-made minced meat into balls of the same size.

Grater - allows you to use the meat grinder as a grater. The meat grinder can be equipped with 2 types of graters - with small and large holes. The grater is inserted through the grater (or vegetable slicer) head.

Attachment for shredding (vegetable slicer)- cuts vegetables into slices. It is inserted into the meat grinder through the vegetable cutter head.

Juicer- designed for preparing citrus juice.

(3 perforated disks, 2 sausage attachments, 50 mm metal auger (No. 5) with a plastic tip (serving as protection against overheating), hardened steel knife, knurled nut)

When choosing a meat grinder, do not forget to check how convenient it will be for you to store it, whether there are compartments on the body for storing attachments, what is the length of the cord, whether there is a device for winding it, etc. Check how stable the device is, what the design of the legs is, what material they are made of (preference is given to rubber legs)

tell friends

A meat grinder is an electrical or mechanical device used for processing food products - meat and others, by grinding them. This device can be called indispensable kitchen appliance, playing important role in the process of preparing a variety of dishes.

Purpose of meat grinders

The main purpose of this kitchen appliance is to grind food. It is used to produce minced meat, fish or poultry. Besides this device copes well with the processing of some vegetables - both raw and after their preliminary heat treatment.

Reference! If necessary, a meat grinder allows you to crush nuts. By connecting a variety of attachments to the device, its functionality is significantly increased.

Electric meat grinder

Electric meat grinders are currently in significant demand. This is primarily due to their large number of advantages in comparison with other types of these devices. This applies to significant power, higher level safety, as well as the absence of the need for rigid fixation on the table.

Device

In order to understand the principle of operation of an electric meat grinder, you need to understand its structure. This device consists of the following parts:

metal or plastic body;
lattice;
knife for food processing;
fixing disk;
electric motor;
pusher;
minced meat receiver;
tray;
screw shaft

Reference! Additionally components electric meat grinders can have a variety of knives, attachments or auxiliary devices.

Principle of operation

Well-cut food products should initially be placed in the meat receiver. Using a pusher, pieces of meat are pushed by a person into the sleeve, after which they fall onto the augers. They have ribs that make it possible to reduce the volume of the largest particles. After passing through this mechanism, the crushed pieces collide with the grid. Slowly pressing through the latter, they are cut through sharp knife, smoothly sliding along the surface.

Operating rules

In order for the electric meat grinder to be in good functional condition for a long time, it is necessary to adhere to some rules, such as:

Pieces of meat should not be sent for processing along with bones.
All components of the device must be thoroughly washed and dried after use.
You need to constantly monitor the sharpening of the cutting elements. This will reduce the rate of engine wear.

By following the above rules, you can achieve long-term and reliable use of an electric meat grinder in the kitchen.

Mechanical meat grinder

Mechanical meat grinders are losing their popularity a little at the moment. Their main advantage is low cost. However, these devices have some disadvantages - low power and the need to be fixed on the edge of the table. Moreover, it is worth noting high level dangers of working with a hand-held device.

Device

The standard assembly of a mechanical meat grinder consists of 9 important elements, such as:

metal body;
trumpet;
screw shaft;
blade or disk knife;
nozzles;
metal grating;
fasteners for fixation;
pen;
screw.

Additionally, some models of mechanical meat grinders use other parts.

Principle of operation

By turning the handle of the device by a person, its grinding mechanism is launched. In parallel with this, the user must feed crushed food particles into the meat receiver, after which they enter the shaft. The latter allows you to divide the largest pieces into smaller ones. In addition, it promotes their advancement towards the grid. Passing through the latter, homogeneous minced meat is produced.

Operating rules

The basic rules for operating mechanical meat grinders are as follows:

It is necessary to ensure that the knives you use are sharpened.
After using the device, all its parts must be thoroughly cleaned of food residues and dried.
Do not feed meat with bone fragments into the device.
All parts of the device must fit carefully to each other.

By following the above rules, you can ensure long-term operation of a mechanical meat grinder for more than ten years.

Meat grinder - The best way grind meat and other products. In other words, cut them into tiny pieces.
Probably in every house there are some that we inherited from our grandmothers. metal devices, with the help of which they “twisted” the minced meat, making remarkable physical efforts for this. With the advent of new technologies, this difficult everyday task has turned into an exciting procedure for grinding a variety of products to realize the most interesting recipes. This does not require male power, and time is saved.

Despite the fact that there are many models of household meat grinders offered by manufacturers, there are only two main types of such devices for grinding products: mechanical and electric.

Mechanical meat grinder

This type is the most basic design devices for producing minced meat, invented at the beginning of the nineteenth century. It is distinguished by its simplicity and accessibility, and functions only when controlled manually using a special handle.

Distinctive features:

Mechanical devices are smaller in size compared to electrical ones and can shred less a large number of products at one time.
Simple, standard, easy-to-use design consisting of parts made from epoxy-coated cast iron, tin or of stainless steel.
This a good option for people on a budget, with a small family and planning to grind only a small amount of meat.

Electric meat grinder

Electric meat grinder has great advantage in terms of use work force. It does not require any human assistance and can simultaneously process a large number of products.

Distinctive features:

Hard parts raw meat, which a manual machine cannot handle, can be easily crushed in such a machine.
She not only works with high speed processing, but also chops a large amount of meat in a short period of time. Consumers who prefer precision and speed in their kitchen are in favor of such a device.
Electric shredders come with a variety of settings to choose from. You can choose very finely or coarsely chopped meat depending on your preference.
Stainless steel grates along with a four-blade knife make this machine work electric machine especially highly effective.

General operating principle

The meat grinder has a funnel at the top of the feed hopper through which you add the cubed meat or whatever you want to grind into the meat receiver. From the funnel, the food is transferred to a screw conveyor. This is achieved using a manually operated torque mechanism or an electric motor. The auger, constantly rotating, steadily pushes the meat down the shaft towards the knife. In this case, large pieces are cut into smaller pieces using ribs on the auger.

The knife and grid are what do the final chopping. The knife is a small cross-shaped piece of metal with sharp blades on each blade that rotates against a grid, also called a die. This is a round metal plate with holes cut in it. As the auger continuously pushes the meat towards this grid, the knife blades slide along its flat surface, grinding the meat into mince. Its texture depends on the size of the holes in the grate. The smaller they are, the finer the minced meat will be.

The disk cover, screwed to the body, reliably presses all the parts together and maintains the integrity of the structure.

Differences

In addition to the fundamental difference in the control method: using a handle that drives all the components and parts of the device, or an electric motor, the main types of devices for grinding products have some other design features.

Mechanical

Must be attached to some stationary flat surface, such as the edge of a countertop. This is done using feet with rubber pads at the bottom of the case and a screw clamp. With this clamp, the legs are tightly screwed to the edge of the tabletop, which ensures reliable fixation of the device during operation.

Electrical

They have a fairly massive body, inside of which there is an electric motor, and rubberized legs on the bottom. This ensures static immobility of the device.
There is an on/off button on the body.
At the top of the meat receiver there is a tray on which you can store pieces of prepared food before pushing them using a pusher into the loading hopper. The larger this tray, the more convenient it is to grind large batches of food.

How to choose

Before you start choosing a meat grinder, answer yourself a few questions:

What type of meat will you be grinding?
How much meat do you want to process in an hour?
How often will you use it?

By answering these questions, you will get a clear idea of the device that will meet the necessary criteria:

Engine

The engine power determines the performance of the mechanism, that is, the amount of products that can be crushed in an hour. Usually two power levels are indicated - nominal and maximum. Normal operation requires power ratings ranging from 400 to 1000 W.

However, in case of extreme loads, for example, when processing accidentally caught cartilage or bones, it will be necessary maximum power engine. It can range from 1500 to 3000 W. This mode of operation should not exceed a strictly defined amount of time (usually no more than 60 seconds). If this condition is not met, there is a risk of rapid wear and tear of the motor.

Meat grinders with the most powerful engine capable of grinding up to 3-4 kg of meat in 1 minute, less powerful ones - 1-2 kg. Optimal choice for the average family there will be a meat grinder with a power of 1000-1500 W and a capacity of 1.5-1.8 kg of minced meat per minute.

Motor damage protection function

If any solid particles, such as bones or tendons, get in, even the most powerful motor can overheat. IN modern models There are two ways to protect against breakage or burning:

Engine blocking using a safety heater. In case of emergency situation(when a certain temperature threshold is crossed) this sleeve bursts. The engine is blocked and disconnected from the network. To resume operation, it is necessary to replace the plastic safety sleeve, which is often included in the kit.
Another way to protect the engine from combustion is a bimetallic strip under the power button. When the engine overheats, the bimetallic strip snaps off the power button and the power supply is cut off, the engine stops. Further resumption of work is possible after cooling down.
The presence of such simple functions will add additional reliability to the engine and can significantly extend its service life.

Material of construction

All devices are made from different materials. Most often it is plastic, metal alloy or stainless steel. A meat grinder with a metal or steel body is more durable and durable. And, if the material of manufacture is not so important for the case, then the internal parts must be made of stainless steel. Only these can withstand heavy loads during operation of the device.

Additional accessories

All people like to receive extra fun from purchase. If we talk about a meat grinder, then the first auxiliary equipment There may be additional grates that allow you to adjust the texture of the resulting minced meat. Most of them have only two grids (for coarse and fine grinding of food), but there are also those that come with attachments that have various holes for making sausages, dough rolls, or in various ways cutting vegetables.

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.

An electric meat grinder has a more complex structure compared to a mechanical one, but its functions remain 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 the working mechanism is made of cast iron, 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 of a 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 the 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 those who prepare diet 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"- top 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 different quantities 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 grill 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. When the load exceeds the permissible value, it automatically turns off. IN gears often installed plastic bushings, 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 one manual meat grinder, but the screw receives 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 towards opposite sides. The sickle-shaped knives receive rotational motion at high frequency (over 8000 rpm) 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 with using a special food grade plastic, which withstands 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 can be in 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.
