Method to operate a grinder

A method to grind meat in a grinder, comprising:

• providing the meat to a grinder via a hopper;
• transporting the meat by a feeder worm to a rotating processing worm, the processing worm conveys the meat towards a cutting set;
• grinding the meat with the cutting set;
• detecting an overload of the feeder worm;
• and
• rotating the feeder worm in a first rotational direction, and if the overload of the feeder worm is detected, reversing the first rotational direction of the feeder worm to a second rotational direction for a certain period of time and then reversing the feeder worm back to the first rotational direction;
• maintaining a rotational speed of the processing worm during rotation of the feeder worm in the second rotational direction;
• maintaining a rotational direction of the processing worm while the feeder worm rotates in the second rotational direction;
• reversing back a rotational speed of the feeder worm to a same speed of rotation as an initial rotational speed of rotation of the feeder worm;
• and
• wherein initially, the feeder worm and the processing worm rotate in a common direction.

A method to grind meat in a grinder;

• comprising:
• providing the meat to a grinder via a hopper;
• transporting the meat by a feeder worm to a rotating processing worm;
• the processing worm conveys the meat towards a cutting set;
• grinding the meat with the cutting set;
• rotating the feeder worm in a first rotational direction, if an overload of the feeder worm is detected, reversing the first rotational direction of the feeder worm to a second rotational direction for a certain period of time and then reversing the feeder worm back to the first rotational direction;
• automatically shutting down the grinder after the overload occurs twice within 3-8 minutes;
• maintaining a rotational speed of the processing worm during the second rotational direction of the feeder worm;
• maintaining a rotational direction of the processing worm while the feeder worm rotates in the second rotational direction;
• wherein initially, the feeder worm and the processing worm rotate in a common direction;
• wherein the feeder worm rotates between 0.5 and 3 revolutions in the second rotational direction;
• reversing back a rotational speed of the feeder worm to a same speed of rotation as an initial rotational speed of rotation of the feeder worm,
• manually or automatically reversing the first and/or second rotational direction of the feeder worm,
• wherein an axis of rotation of the feeder worm is generally parallel to an axis of rotation of the processing worm,
• wherein the overload of the feeder worm is detected with a sensor that detects a speed of rotation of the feeder worm, and if the speed of the rotation of the feeder worm is not maintained at a preset speed, the rotational direction of the feeder worm is automatically reversed.
