ABSTRACT:
The apparatus comprises a vat having a lateral wall and a bottom for pasteurizing, maturing and maintaining a product. A cover adjacent to the lateral wall and to the bottom controls the temperature of the product present in the vat. A first heat-exchange circuit is defined by the cover and by the vat. A heat-exchange fluid circulates in the first heat-exchange circuit. The first heat-exchange circuit includes a heat generator for the heating of the heat-exchange fluid and includes a first heat exchanger for the cooling of the heat-exchange fluid. A second heat-exchange circuit has a tank. A diathermic liquid circulates in the second heat-exchange circuit. A second heat-exchanger is disposed in the tank, and a refrigeration group is connected, in a heat-exchange relationship, to the second heat-exchanger. The second heat-exchange circuit is connected to the first heat-exchanger by a by-pass conduit parallel to the first heat-exchanger. A first on-off valve is connected to the by-pass conduit and has a second on-off valve connected to an inlet of the first heat-exchanger to selectively control the flow of diathermic liquid passing from the second refrigeration circuit. A cleaning circuit has a cleaning water tub, an inlet, and an outlet communicating respectively with a cleaning water source and a discharge drain. An electronic control system programs and commands the preparation and distribution of the product.
