What can be cooked from squid: quick and tasty

Dear visitors!!!

As we know, grinder knives are sharpened by specialists working in workshops, which are equipped with the appropriate equipment. But usually, we do not have everything. free time and the opportunity to visit specialized workshops to meet their needs.

Usually, for grinding circular knife(lattice) and sharpening the cutting edge of the cross-shaped knife (for a meat grinder) - you can use an electric emery.

Electric emery

Currently, electric emery is available in a large assortment in specialized stores, which of course meet their technical requirements.

Nevertheless, for some reason, we have to make this electrical appliance with our own hands. The purchase of an emery wheel and a nozzle, which is installed on the rotor shaft of the electric motor, can be attributed to an insignificant cost for the manufacture of electric emery. The electric motor itself for emery is borrowed most often - from unnecessary washing machine... It should be noted here that for grinding the grating and sharpening the cross-shaped knife, there should be no radial and end beating when the emery wheel rotates. The end and radial runout of the rotating emery wheel will depend on how you set the emery wheel. That is, initially it is necessary to determine the displacement of the emery wheel (when it rotates) and then, to eliminate its beating.

Nevertheless, in terms of quality, preference should be given to special types of machines designed for grinding the grate and sharpening the cross-shaped knives of the meat grinder.

Grinder knife sharpening machine

With the help of this sharpening machine, you can set the required angle for sharpening the cutting edge of the knife, as well as grind the grinder itself directly.

If there is no such opportunity to purchase a sharpening machine for meat grinder knives and other cutting tools, I suggest you watch the video, which, I think, contains useful information.

That's all for now. Follow the rubric.

it homemade device allows you to sharpen knives and grinder grates correctly and quickly. In fact, these are two nozzles for a screwdriver or drill, the design of the devices is made in such a way as to evenly distribute the force over the entire plane during sharpening.

Materials needed:

• Two long bolts and 4 nuts for them.
• Two thin bolts and two nuts.
• Two springs.
• Two washers.
• Metallic strip.

This is how the attachments for sharpening a knife and mesh look like.

We start by making a knife sharpening device.

We measure the size square hole grinder knife.

We take a long bolt and grind the head under the square, the hole of the knife.

Now we assemble the device as follows: we put on a bolt with a square head - a washer, then a spring, another washer, two nuts. We pull the spring with nuts so that pressure is created and the spring does not dangle.

We tighten the nuts together with two keys.

The grinder knife sharpener is ready.

Now let's start making a device for sharpening the grinder mesh. We take a strip of metal and drill three holes in it, the central one for a large bolt and a couple of side holes for small bolts. It should be noted that the side bolts must fit into the outer holes of the mesh.

We assemble, insert the central bolt, first screwing one nut onto it, fix it with another nut.

Insert thin bolts of the same length into the side holes and fix them with nuts in the same way.

It is important here that the center bolt is below or equal to the length of the thin bolts relative to the level of the rectangular plate.

This is how we made devices for sharpening knives and nets of a meat grinder.

The process of sharpening the mesh is as follows: first with coarse sandpaper, then with a fine one, and at the end with the finest one.
We put on a flat surface or other material, it is important that the surface is perfectly flat. Then we put sandpaper with a large grain on top, then the mesh knife itself.

We lower the device so that all the bolts fall into the holes. There is no need to follow through to the very end. It is necessary for the spring to create pressing forces.
We turn on the drill and sharpen the mesh within a few minutes.

An old manual or new electric grinder in the house is a must. Cooking minced meat is a matter of several minutes, but this requires a working meat grinder, which will not let you down in the midst of work. And if the unit malfunctions, the answer is always the same - dull knives. So the question arises of where and how to sharpen a knife for a meat grinder, if it is needed at the most crucial moment.

The device and principle of operation of the meat grinder

To understand how the knives work and why it is necessary to constantly monitor the condition of the cutting surfaces, consider the device and principle of operation of the unit.

The meat grinder consists of the following units:

1. cast body (cast iron or aluminum alloy);
2. cast auger (cast iron or aluminum alloy);
3. movable four-blade knife;
4. fixed grid with many holes;
5. large front nut;
6. a handle for rotating the auger (in electric meat grinders - an electric motor).

The meat is loaded into the receiving hopper, from where it is fed to the fixed mesh by means of an auger. Here the process of cutting meat takes place between the fixed mesh and the movable four-blade knife. Chopped meat in the form of minced meat is pressed through the mesh openings into the receiving container.

When sharpening is needed

To understand why sharpening is needed, you need to understand how all the details work during the production of minced meat.

When buying a meat grinder, all parts are completely new, since they have not been in operation. Therefore, the knives have an ideal contact surface. This is very important when the unit is running. There is a perfect cut of the next portion of meat that falls into the working area of ​​the unit.

But after some time of operation, the meat grinder begins to malfunction. If the unit is manual, then you have to apply more force to rotate the handle. With an electric drive, there are interruptions in the rotation of the auger, overheating of the electric motor and its possible breakdown.

With an ideal way out of the situation, it is enough to buy spare parts from the store and, after replacement, continue to work calmly. But even this option cannot suit the hostess. After all, buying parts is economically unprofitable. It is necessary to figure out what is happening and how you can get out of the situation without buying new parts.

What happens to the grinder

After buying a meat grinder in a store, you must read the instructions for use. Almost all manufacturers assure customers that the knives of their unit do not have a wear life and even sharpen themselves. Allegedly, during operation, the movable cutter, tightly in contact with the stationary mesh, slides along it and mutual self-sharpening occurs due to friction. But in reality, we do not observe this. Indeed, even in electric meat grinders, cutting parts are made not of high-quality steel, but of ordinary steel.

When grinding the product, tendons, all kinds of inclusions, up to small fragments of bones, get into it. As a result of such work, the usual bluntness of the cutting parts occurs and the process of grinding the minced meat is disrupted. After a while, the meat grinder simply does not grind the meat, but crushes. Then the question arises of where to properly sharpen the knives for the meat grinder.

Grinder knife sharpening

So that you are not tormented by the question of where you can sharpen the knives for the meat grinder at the time of minced meat production, try to regularly inspect the parts. To do this, simply disassemble the unit and inspect the condition of the cutting units. If the surface is covered with rust, it must be grinded to prevent destruction by corrosion. You always have a choice: where to sharpen the knives for the meat grinder.

If you prefer to entrust this work to specialists, then you can contact one of the sharpening centers of specialized enterprises in your city.

Sharpening knives in the workshop

If you decide to sharpen the cutting parts in the workshop, then this should be done in advance. It is necessary to inspect the meat grinder once a month and identify all defects.

In workshops for ezochki used grinding machine Adems and used grinding abrasive stones.

If you have such a machine in your home workshop or garage, then you can sharpen your knives at home. Let's see how this can be done.

The machine consists of an electric drive and a horizontal faceplate. To perform this operation, you must:

• grease the plan washer over the entire surface with oil;
• sprinkle abrasive powder on the lubricated surface and distribute it evenly over the faceplate;
• turn on the machine and, using a magnetic holder, set the knife to be processed on the faceplate, pressing it in the center.

After surface treatment, another element is placed on the machine. Thus, the horizontalness of the working surfaces, working in a pair of parts, is achieved. The next operation is sharpening the edges of the movable four-blade cutter at an angle of 80 degrees using a grinding abrasive. The final touch is grinding the cutting edges of the movable knife and the horizontal surface of the grating on the vulcanite stone.

Sharpening the house with sandpaper

What to do if you understand during the production of minced meat: meat is not cut, but "chewed"?

You can sharpen knives at home. The easiest way to sharpen cutting element- at home with your own hands. Need sandpaper to sharpen fine-grain knives. It is not advisable to use coarse-grained skin, as it can damage the surface of the knife. Indeed, when sharpening knives in this way, it is impossible to allow a lot of wear and damage to the cutting surfaces.

Sharpening is carried out on a perfectly horizontal surface. Having secured a sheet of paper, we begin to rub it with the processed surface of the knife until we achieve a clean working surface. We do the same with the other knife. After finishing the processing, we check the parallelism of the surfaces in the light. Ideally, there is no gap visible between the cutter and the grate.

You can check the meat grinder with the help of threads inserted through the grill of the meat grinder in assembled form. Turning on the electric meat grinder, the cut threads should fall on the table.

On a grindstone

You can sharpen knives using sharpening stones. To do this, in the store we buy a whetstone made of corundum from 40 to 60 microns. We make a platform from a board to strengthen it and provide water supply during work. Having strengthened the stone on a stand, having previously moistened it with water, we begin to sharpen the movable element, making circular rotational-translational movements. In this case, a fine abrasive paste is formed, which brings the surface to grinding. Periodically rinse the torch in water. When a shiny surface is reached, the part is considered to be sharpened.

We carry out the processing of the mesh in the same way. At the same time, we check the fit of the knives for the clearance of the surfaces. If there is no gap between the applied working surfaces, then the sharpening result is achieved and the grinder can be tested in operation.

On a grinder

The two previous methods work in the event that the production of cutting parts is insignificant, you just need to make a small reconstruction of the cutting edges and contact surfaces. For more serious wear and tear, a sharpening machine will help you.

When starting work, it is necessary to check the condition of the working disk of the machine. It must be perfectly flat and used only for sharpening work..

1. Must be applied to work surface disk GOI No. 4 paste and let it dry.
2. Then we turn on the machine and when the disk picks up speed, we begin to work.
3. Pressing the mesh to the disk, we carry out the processing until a uniformly shiny surface is obtained.

When processing a knife, it is necessary to work intermittently in order to prevent overheating of the workpiece.

Then we start sharpening the four-blade movable cutter. Here the work is carried out in stages..

Work on grinder will be efficient and fast if you know how to work and follow safety rules.

With the help of this simple adaptation you will be able to sharpen your mincing knives quickly and correctly. Fast, because a drill, machine or screwdriver is used to rotate the knife, and rightly so, because the device gives the optimal pressing force on the entire plane without skewing.

It will be needed to assemble the fixture

• A pair of long balts with four nuts to them.
• A pair of thin bolts with two nuts to them.
• Two springs.
• A piece of thin steel plate.

Making a device for sharpening meat grinder knives

Grinder knife sharpening

It is difficult to imagine a modern kitchen without such a useful mechanism as a meat grinder. With its help, any housewife can do without even a food processor. But over time, even the sharpest blade becomes dull and ceases to perform its functions. The way out of this situation is quite simple - you need to sharpen the knife again. We will talk about the methods of sharpening further.

Characteristics of knives

Any meat grinder has at least two knives:

• stationary;
• mobile.

One of them is motionless. It is a circle with many small holes. The second knife is a spare part with several blades usually with four. During operation, the knife rotates and due to this, the products are chopped. And then the crushed pieces are pushed through the holes of the stationary part.

Breakdown reasons

One of the parameters of a good grinder operation is the sharpness of the cutting edges of the movable blade. However, when there are small bones or veins in the meat, the blade becomes dull. Gradually, more effort is needed to grind the food.

Another parameter effective work Is the distance from the stationary part to the moving part. The smaller this distance, the better the grinding will be. Over time, due to wear, this distance increases. In addition, due to the fact that knives, as a rule, are made of black metal, they, oxidizing and rusting, lose their sharpness.

So that reduce the amount of effort needed to grind food(and in modern conditions and the amount of consumed electricity), you need to sharpen the blades for a meat grinder in a timely manner.

Grinder knife sharpening techniques

There are several options for sharpening a knife:

Whichever sharpening method is chosen, it is imperative to carry out preparatory work. Lubricate the blades with sunflower oil and let dry for 5-10 minutes. It is also necessary to do the same with the sharpening tool. This is required so that the sharpening tool does not deteriorate at the very beginning of work. Moreover, such preparatory stage prevents the formation of splinters due to possible incorrect position of the knife during sharpening.

Using a special machine

The most convenient option, of course, is to use a special machine. It is designed specifically for sharpening meat grinder blades and has a smooth abrasive surface. Before work a special paste is applied to the disc which contains the smallest abrasive particles. Due to this, after the composition has dried, the surface of the disc becomes rough. After connecting the device to the electrical network, the disc begins to rotate and the cutting edge of the parts is gently pressed against it. During work, be sure to take breaks to prevent overheating of the metal.

Despite the simplicity of the method, this procedure requires certain skills. If you hold the knives at the wrong angle, you will not be able to sharpen them, moreover, it can be dangerous.

Another the disadvantage of this option is its high cost... A knife sharpening machine is quite expensive and not easy to find in a regular store. Sometimes it is easier and safer to see a specialist or use another method.

Using a whetstone

A sharpening stone is much easier to purchase in a store. It is much cheaper than a machine tool, and there are several options for its use.

First option. Sharpening is done by rotating the knife. In this case, the sharpening stone should be at least 2 times the diameter of the knife. The knife lies in the center so that the blades fit snugly against the surface of the stone.

Holding the knife in the middle of the stone with your hands, you need to make circular movements. Gradually it is necessary to increase the rotation speed if possible... You can finish sharpening if all the blades are the same without chipping and visible irregularities. Moreover, this method of sharpening can only be used on not too dull knives.

The second option is the rotation of the stone. This method is suitable if there is no result from the first. Since the sharpening force will depend on the amount of friction, then the stone must be fine... The size of the stone may not exceed the size of the part. A knife is taken in one hand, a stone in the other. They are tightly pressed against each other and circular movements are made. This procedure can be performed more efficiently by securing the part rather than holding it in your hands. For protection, be sure to use gloves. After the end of sharpening, the blade is allowed to cool and rinsed under running cold water.

Using sandpaper

Another popular way to sharpen a meat grinder knife is to use sandpaper. The thickness of the sandpaper depends on the thickness of the blade. The thicker the metal needs to be processed, the larger the grain fraction should be.

The procedure itself is very simple. Taking a knife in one hand and paper in the other, you just need to gently rub each blade until it becomes sharp. The movements are similar to those that occur if you just wipe the surface.

Thus, if you follow any uncomplicated method, you can keep the meat grinder in perfect condition without resorting to specialists on the side.
