Apparatus for shredding or pulling pieces of meat, which includes a feed hopper carried on a body, a removable shredder roller assembly in the body for shredding the meat, which includes a shredder roller, and a backer plate, which can be adjusted to vary the texture of the shredder meat product, and an electric motor to rotate the shredder roller. A bi-directional AC-to-DC electric power converter interconnects the motor-generator with a DC bus. The receiver extracts the specified bit strings indicating the blanking period from the received data and performs majority processing on the results of demodulation of the extracted bit strings to decide on output data. By the current supply to the sub-coil, a third magnetic flux reducing at least one of the first magnetic flux and the second magnetic flux is generated. The tube can include a compressible material adapted to absorb at least a portion of a horizontal load placed on the lift system.
