Device for continuous sterilization or pasteurization of food products in flexible or rigid sealed packaging, has heat exchanger including cold heat exchanger to capture calories of cooling fluid to cool cooling fluid

摘要

The device (1) has an enclosure including a hydrostatic heating column (20) filled with heating fluid, and a hydrostatic cooling column (30) filled with cooling fluid, where the heating column and the cooling column are connected by an intermediate column (4). A coolant circuit (9) circulates the cooling fluid enclosed in the cooling column, and a heat exchanger (8) includes a cold heat exchanger (80) to capture calories of the cooling fluid to cool the cooling fluid. The heat exchanger includes a heat pump (82) as an interface between the cold heat exchanger and a hot heat exchanger (81).
