Why do you need a reverse function in a meat grinder?
First, you should understand the principle of operation of the meat grinder itself. The auger, which moves pieces of meat to the exit, is equipped at the end with a special cross-shaped knife, which chops the products. Next, the chopped meat is pressed through the grate to form minced meat.
Meat of low quality, containing veins, rough fascia, not everything can be ground. Often there are long, stiff fibers left behind that have no choice but to wrap around the rotating shaft. This reduces the speed, increases the load on the meat grinder, which ultimately can lead to shutdown due to overheating. There is only one way out: periodically turn off the device, disassemble it and remove everything unnecessary from the auger and knife. Reverse is very helpful in such a situation.

Why does a meat grinder need a reverse function?
To understand why reverse is needed, you must first remember how a meat grinder works, what is its main function? For grinding meat, the auger is equipped with a special cutting knife. Its main function is to grind the product. It goes into a grid with holes, turning into minced meat.
However, almost any housewife knows well that sometimes it is quite difficult to make minced meat right away. If you have to deal with a low-quality product that contains a lot of veins, the knives are powerless. The veins scroll along with the contents, constantly hammering the screw as they screw onto it. Spinning the meat grinder all the time to clean the screw is a bad solution. It is in such a situation that reverse will help.
Reverse operating principle
Reverse is the reverse movement of the shaft, which allows you to solve the problem of winding the cores on the auger . His task is not to let the veins pass so far that they wrap around the knife. To do this, the contents of the shaft are returned a certain distance back by reversing the stroke. After this, the device is given a second chance to deal with the stubborn piece of meat. Depending on the type of meat grinder, the reverse may be different.
Reverse in mechanical (manual) meat grinders
We are talking about simple manual meat grinders, which at one time were in almost every home. The shaft rotation is carried out manually. The user rotates the handle, the force from which is transmitted to the free end of the auger. The auger moves synchronously with the handle. This is a very simple mechanism. Reverse, that is, a change in the direction of movement of the shaft, occurs when the direction of rotation of the handle changes.
Attention! The main working movement in a mechanical meat grinder is clockwise. Accordingly, if reverse is needed, the handle must be rotated counterclockwise.
As a result of such actions, the veins from the knife and screw will unwind, and everything that is in the meat grinder will return through the auger back into the loading tray. Here you can select the tendons and send the rest back for processing.
Reverse in electric meat grinders
Both forward and reverse motion in an electric meat grinder occurs without user intervention, in automatic mode. The hostess only needs to give the desired command (using the reverse on/off button).
Physically, the function is implemented in the same way as in mechanical models. The shaft begins to rotate in the opposite direction, moving the products towards the loading tray, freeing the knife and auger from the stuck veins. The direction of rotation changes automatically when a certain button is pressed.
Advantages of meat grinders with reverse function
The reverse function is used in manual as well as electric meat grinders. However, unlike any mechanical device, where reverse motion can be performed by starting to rotate the handle in the other direction, in electrical products the auto-reverse function is considered an additional operation. The manufacturer must indicate the absence or presence of such a function in the product passport.
An electric meat grinder with reverse is very different from manual products. It has a number of advantages that make the work of the kitchen housewife easier.
Benefits of Reverse Motion
- It doesn't take much time to prepare minced meat. The operation is very easy and does not require physical effort.
- The screw is cleaned of twisted particles automatically. The product is not disassembled.
- It becomes possible to grind the meat with a small amount of remaining tendons. When loading product into return motion models, it is not necessary to completely remove all cores in advance.
- Thanks to the quick cleaning of the auger, the device continues to operate evenly, eliminating idle speed. Therefore, sharpening knives is performed much less frequently.
- Devices with reverse are easy to maintain.
- The service life of the product is greatly increased.
Advantages of an electric meat grinder with reverse function
Electric models equipped with a reverse function have a number of advantages over their mechanical counterparts.
- Making minced meat, forming sausages and other operations become fast and can be done just by pressing a button, rather than turning a crank for hours.
- The veins are removed from the knife themselves during reverse. There is no need to disassemble the device.
- For minced meat, you can use raw materials of any quality. There is no need to clean it as thoroughly as for a manual meat grinder. All cores can be removed during the process using reverse.
- Reverse ensures uniform operation of the device, without “stressed” areas. Thanks to this, knives become less dull.
- This type of meat grinder is easier to maintain.
- Since there are no situations when the device cannot cope, it works at the limit, the service life as a whole increases.
Why do you have to use reverse?
When grinding any meat, along with the pulp, you come across harder fractions in the form of veins, films, and bones. They twist poorly and wind up on the auger. As a result, the meat grinder becomes clogged, slows down, and stops.
Then reverse comes to the rescue. The function starts turning the auger in the opposite direction, as a result of which the mechanism is cleared of blockages and can continue to work.
The system significantly saves time and effort, because you do not need to disassemble the device each time, clean it and reassemble it to continue working. In an electric meat grinder, you just need to press a button, and in a manual device, you just need to turn the handle in the other direction.

Is it possible to do without reverse?
It is quite clear that if minced meat is prepared from sirloin, a device of any power will cope with this task. But the housewife is not always able to clean the product from tendons and seeds well. And in the absence of reverse motion, work will be difficult.
Some models of devices have special safety devices to prevent bones and veins from entering the apparatus, but in such cases overheating of the mechanisms can often be observed, which sometimes leads to their breakage . Therefore, manufacturers prefer units with reverse motion.
Although it is believed that low-power devices, from 1000 to 1800 W, need reverse rotation, and high-power devices can cope without it, increasingly devices with a power of 1800 W or more are made with reverse rotation.
Obviously, reverse has an important property. Its use simplifies the process of rolling meat, and many modern brands are equipped with a reverse system. But the presence of such a function is reflected in the cost of the unit. Consider carefully whether you will be using meat with stringy fibers, fish with skin, or vegetables and fruits with skin. If not, then you don’t have to overpay for a meat grinder. It should be taken into account that such household appliances are purchased infrequently. Therefore, you need to be careful when purchasing, with a view to the future, and still choose a model with auto reverse.
Reverse technology
From the above, it becomes clear when the meat grinder requires “reverse”. Meat with veins must be returned, it must be prevented from getting into the grill. To solve this problem, manufacturers equip their devices with a return mechanism. Depending on the model, the reverse can have several varieties.
Reverse stroke in manual meat grinders
Classic models are called manual. Reverse occurs due to manual rotation of the auger. It occurs using a lever secured with a special screw. Rotation is carried out only under the influence of physical force. The handle begins to rotate, the speed is transferred to the auger.
Performing reverse rotation on such models is quite simple. If you need to rotate the meat back, just change the direction of rotation.
For your information! To cook minced meat, you need to rotate the handle clockwise. To obtain reverse movement, you need to rotate the handle in the opposite direction.
As a result, the meat will begin to move backwards. The loading bowl will be filled with meat again. The veins will unwind and the screw will be completely released. The tendons are removed from the container and the process of grinding the product continues.
Reverse function in electric meat grinders
The main advantage of any electric meat grinder is the ability to carry out all operations automatically. The person only monitors the operation of the device, turns it on or off. He also selects a program that determines the direction of rotation of the auger.
Good to know! In models equipped with reverse, reverse rotation occurs automatically after such a command is turned on.
The processing process is similar to the manual model. The workpiece is returned to the bowl, the various tendons become available for removal.
What is reverse in a meat grinder?
Reverse is translated as “reverse motion.” In the case of meat grinders, this means turning the mechanism in the opposite direction and returning the product to its starting point - the loading container.
Important! This system is necessary in order to easily remove unprocessed products from the meat grinder mechanism.
It often happens that too large pieces of meat, with remnants of bones or veins, skin, get stuck between the grate and blades or get wrapped around the auger. Removing such pieces is difficult and dangerous, since there are traumatic parts inside the device.
In this case, meat grinders without reverse must be disassembled and the stuck product removed independently. Reverse allows you to do this quickly without stopping the cooking process.
Reverse in a manual meat grinder
In manual meat grinders, reverse is accomplished by turning the handle in the opposite direction. A few turns and stuck uncut pieces of meat or other product are released from the feed opening, making them easy to remove and spin again.
Reverse in a modern meat grinder
Modern technology has more advantages even in such a simple system. In addition to the power button, electric meat grinders also have an R button, when pressed, the reverse motion begins.
The principle is the same - the mechanism rotates in the opposite direction, the product returns to the starting point. This does not require any effort; the pieces that did not pass through the knives can be immediately returned to the meat grinder.
