    • The meat mincer appliance has a cooling system of Peltier units (11A-11C), with electronic control from a temp. sensor (26) for the power to give a controlled temp. stability. Pref. further Peltier units (13A-13B), with their cool sides, are below the meat supply dish (36). The current supply for the Peltier units (11A-11C;13A-13B) may be without a transformer, through a mains voltage rectifier and an electronic temp. control circuit (22), switched in series with the Peltier units (11A-11C;13A,13B). Alternatively, the power supply is through a transformer with a low voltage through a rectifier and an electronic temp. control circuit (22) switched in parallel with the Peltier units (11A-11C;13A,13B). The warm sides of the Peltier units (11A-11C;13A,13B) are connected to an air/liquid heat exchanger (24), subjected to an outer air flow through a fan (23), through a pumped liquid recirculation with a heat carrier medium of water or glycerine or similar coolant.
