Sharpening the knife for meat grinders at home

Meat grinder is an indispensable tool in the kitchen. With its help, you can easily grind any product necessary for cooking a delicious dish. However, the knives of the meat grinder are gradually being ground. In such situations, their sharpening is required. Can I do it myself?

Preparation

Sharpening a knife for a meat grinder is a simple process. However, before starting work, you should carefully prepare the part and tools. The meat grinder knife and grate should be thoroughly cleaned. After this, the part should be greased with vegetable oil and leave for five minutes. During this time, the knife should dry slightly. This is necessary not only for high-quality sharpening, but also in order not to damage the sharpening tool, which is also recommended to lubricate with oil. It is worth noting that this procedure allows you to reduce the risk of chipping when the blade is turned incorrectly.

Sharpening a knife for a meat grinder: the main ways

Before you begin to sharpen the knife, it is necessary to determine the method. There are several main ways, among which:

1. Grinding of knives and grate grinder with a special machine.
2. Application of grindstone.
3. Use of sandpaper.

Each of the methods has its advantages and disadvantages. If desired, you can choose the method that is most convenient.

Using a special machine

Sharpening the knife for a meat grinder with a special machine is the most convenient method. The device is equipped with a smooth surface coated with an abrasive compound. It looks very much like a disk. Before sharpening on this surface it is necessary to apply a special paste. The agent has in its composition small abrasive grains. The paste dries quickly enough. After applying this tool, the disc becomes rough.

When the instrument is ready for operation, it must be started. After the start, the disc starts to spin. The knife from the meat grinder must be gently pressed with a blade to the surface of the circle. Sharpening in this case is carried out in several stages. After all, the metal can become very hot during the process. Breaks are required in order for the blade to cool down.

Disadvantages of this method

Sharpening a knife for a meat grinder with a special machine has several drawbacks. Among them is the following:

1. Complexity of sharpening with insufficient experience. Anyone who has never done this kind of work can not accurately determine at what angle it is necessary to grind the blade of the meat grinder. In addition to this for beginners, this can be unsafe. It is for this reason that the sharpening of the knife for the meat grinder should be carried out only by professionals.
2. The cost of the machine. Prices for such structures are quite large. At the same time, it is almost impossible to purchase a machine in an ordinary store. Therefore, when choosing the method of sharpening the knife, one should think about whether it is worthwhile to spend money on special equipment.

Application of grindstone

In this case, grinding knives for meat grinders at home is carried out with a grindstone. To grind, you should take a grindstone, the surface of which has an area several times larger than the diameter of the part. The fraction should be rather shallow. Otherwise, the quality of the sharpening will be affected or it will take more time.

The knife of the meat grinder must be placed on the surface of the grinding stone so that it is snug against it. After that, the part needs to be moved around in a circle, holding your finger in the center. At the same time, pressure must be applied to the knife. Gradually, the rotation speed should be increased.

Features of this method

When sharpening knives with this method, it is necessary to periodically check the blade. If it has no gaps and chips, then the procedure can be considered complete. The knife should become more homogeneous. However, when choosing the sharpening method, it is worth considering that this method is suitable only for slightly blunt blades. If the knife is completely worn out, then a cardinal approach is required.

The second method of grinding with a grinding stone

In this case, the grinding stone itself rotates. There is no need to buy a knife grinder. For work, you can use a tool that matches the diameter of the blades in size. The surface of the grindstone should have a shallow fraction. Due to the friction of the surfaces, sharpening will be carried out.

Before you start, you should wear a glove to protect yourself. Then grind the grinding stone firmly to the knife of the meat grinder. The tool needs to be rotated in a circle. If there is a possibility, then it is better to fix the knife, so as not to hold it in your hands. After sharpening, the part should cool slightly. For this, the knife can be placed under a stream of cold water. This will also remove the debris from the metal. This method is suitable for sharpening heavily blunt blades.

Use of sandpaper

Experts do not recommend doing anything yourself unless you know how the knives are sharpened for meat grinders. In St. Petersburg, Moscow and large cities, there are special companies that deal with such things at a professional level. If there is no such organization in your city, then you can use sandpaper for grinding.

The thickness of the material depends on the thickness of the knife. For a thick metal, sandpaper with a coarse fraction is required. To begin with, you need to pick up a dull part. Now it is necessary to rub each blade of the part with sandpaper. Repeat the procedure until the knife is sharp enough. Finally, the part should be washed in running water to remove the metal fragments.
