This particular model appears to be a commercial-grade meat grinder, potentially used in butcher shops, restaurants, or food processing facilities, designed for heavy-duty tasks like grinding meat or even bones.
It features a funnel for loading meat, a screw conveyor to push and mix the food, and a blade and plate mechanism for grinding.
The large blue wheel on the side suggests it's a belt-driven model, likely powered by an external motor.
The size of the holes in the grinding plate determines the fineness of the minced product.
