Meat grinder .. The machines we use every day and how they work

Meat grinder:

The most important part of the meat grinder is a long, rotating screw. It is noted that despite the importance of this screw, it cannot do this work alone. It must be provided with a nut, but it must be of a certain type. Then this nut can move - if the screw is turned - and perform a valuable work. This work is similar to the process of pushing the lead shaft in a pencil, or the movement of the jaws in a sickle. So let's look for this nut that fits the rotating screw in the meat grinder.

You cannot find this suitable nut unless you actually put some meat in the tooth of the grinder. When you put the meat on the screw, the piece of meat itself becomes a nut! The meat wraps around the teeth of the rotating screw, and when you turn the grinder hand, the meat moves forward just as any nut moves if you turn its rotating screw.

The meat moves forward towards a disc with sharp holes, and the nail, as it rotates, forces the meat forcefully through these holes, and then the piece of meat comes out cut into thin threads.
