Apparatus for preparing and distributing fermented diary products

An apparatus for preparing and distributing fermented dairy products comprising:

• a vat having a lateral wall and a bottom for pasteurizing, maturing and maintaining a product;
• a cover adjacent to said lateral wall and to said bottom for controlling the temperature of the product present in the vat;
• a first heat-exchange circuit defined by said cover and by said vat, a heat-exchange fluid circulating in said first heat-exchange circuit, said first heat-exchange circuit including a heat generator for the heating of said heat-exchange fluid and including a first heat exchanger for the cooling of said heat-exchange fluid;
• a second heat-exchange circuit having a tank, a diathermic liquid circulates in the second heat-exchange circuit, a second heat-exchanger being disposed in said tank, and a refrigeration group connected, in a heat-exchange relationship, to the second heat-exchanger;
• said second heat-exchange circuit being connected to said first heat-exchanger by a by-pass conduit parallel to the first heat-exchanger, a first on-off valve being connected to the by-pass conduit and having 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 having a cleaning water tub, an inlet, and an outlet communicating respectively with a cleaning water source and a discharge drain, a first conduit placing the washing tub in communication with the inside of the vat, and a second conduit connecting the discharge outlet of the vat to the tub;
• and
• an electronic control system for programming and commanding the preparation and distribution of said product.
