Abstract:
1. A machine for homogenization and thermal treatment of at least one chosen from a liquid food product and a semi-liquid food product, comprising a containment tank for a mixture of the at least one chosen from the liquid food product and the semi-liquid food product, a centrifugal pump for pumping the mixture, the centrifugal pump having an intake opening in fluid communication with a bottom of the containment tank for drawing mixture from the tank and a delivery opening in fluid communication with the tank for returning the pumped mixture back into the tank, and a heating and cooling mechanism acting at the centrifugal pump for selectively heating and cooling the mixture in transit in the centrifugal pump, the heating and cooling mechanism comprising a thermal machine with a reversible transcritical thermodynamic cycle, using carbon dioxide as a refrigerant, for selectively heating and cooling the mixture.
