A meat grinder includes a motor including a stator and a rotor including a motor shaft, a transfer case operatively coupled to the motor shaft, and a grinder head operatively coupled to the transfer case. The grinder head includes an inlet into which a raw meat product can be fed and an outlet through which ground meat can be discharged. Rotation of the motor shaft imparts operation of the grinder head via the transfer case. The motor also includes a housing comprising a generally cylindrical outer wall that is spaced from the stator thereby creating a cooling channel between the stator and the outer wall. The housing further includes a front wall including a plurality of inlet openings and a rear wall including a plurality of outlet openings. The motor also includes a heat sink inside the housing positioned in the cooling channel adjacent the motor stator. The motor further includes a cooling fan coupled to the motor shaft and positioned adjacent the rear wall. During operation of the meat grinder, the motor rotates the cooling fan which discharges air from the housing through the outlet openings, which draws air into the housing through the inlet openings, creating air flow through the cooling channel, the air flow through the channel drawing heat from the heat sink prior to being discharged through the outlet openings.

A system includes a grinder to obtain a ground meat; a mixer to add fat to the ground meat; a payload bay to receive the ground meat; a plurality of evaporators coupled to the payload bay; a pump to force coolant flowing through the evaporators; and means for adding fat to the chopped meat product and then chopping the fat and adding liquid nitrogen to maintain the temperature of the chopped meat product and fat being chopped between 1° C. and 10° C. to obtain a chopped meat and fat product.

An apparatus for cooling a food processing grinder head with an integrated heatsink is captively retained between two halves of a cooling pack. The heatsink and cooling pack have a circumference that matches the circumference of the grinder head thereby attaching to and in direct thermal communication with the grinder head.

A freezer includes a grinder to obtain a ground meat; a mixer to add fat to the ground meat; a payload bay to receive the ground meat; a plurality of evaporators coupled to the payload bay with a multiplicity of coolant tubes in each evaporator, wherein each tube enters and then exits the payload bay, further comprising one or more cryogenic valves coupled to the coolant tubes; a pump to force coolant flowing through the evaporators; and a processor with code for: chopping the ground meat and during chopping, adding salt and ice to the ground meat being chopped and adding liquid nitrogen to maintain the temperature of the meat being chopped below 5 C. to obtain a chopped meat product; adding fat to the chopped meat product and then chopping the fat and adding liquid nitrogen to maintain the temperature of the chopped meat product and fat being chopped between 1 C. and 10 C. to obtain a chopped meat and fat product, wherein the ground meat, added fat, ice and salt are present in amounts so that the chopped meat and fat product has a fat content of from 1% to 20% by weight based upon the weight of the chopped meat and fat product.
