Machine for the homogenization and thermal treatment of liquid and semi-liquid food products

摘要

A machine for the homogenization and thermal treatment of liquid and semi-liquid food products, for example ice creams, whipped cream, creams, chocolate, yogurt and the like, comprises a containment tank for the mixture and a centrifugal pump put in fluid communication with the bottom of the containment tank for drawing mixture from the tank and putting it back into the tank, heating and cooling means acting at the pump for heating and cooling the mixture in transit in the pump. The heating and cooling means comprise a thermal machine with reversible thermodynamic cycle and using carbon dioxide as refrigerant.

主权项

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.
