Patent ID: 8156857

Claim:
Improved equipment for yeast rehydration, in particular for oenology, which comprises: a containment tank ( 2 ) susceptible for receiving a measured dose of yeast in dry or paste form to be rehydrated; first supply, device ( 3 ) adapted to insert a rehydration liquid in said tank; second supply device ( 4 ) adapted to insert nutritive substances in said tank; wherein said yeast, said rehydration liquid and said nutritive substances form a fluid mixture; at least one circulation duct ( 14 ) placed in connection between at least one outlet opening ( 15 ) and at least one return opening ( 16 , 16 ′) of said containment tank ( 2 ), intercepted by a pumping device ( 17 ) for making said fluid mixture flow between said openings ( 15 , 16 ); wherein said equipment further comprises an air insufflating device for insufflating air ( 32 ) inside said tank ( 2 ) which insufflating device is actuatable independently of said pumping device ( 17 ) for the circulation of said fluid mixture in said circulation duct ( 14 ) and is susceptible for creating an over-pressure of a value that can be set through a vent ( 18 ), wherein said air insufflating device is actuatable independently of said pumping device for the circulation of said fluid mixture in said circulation duct ( 14 ); and said vent ( 18 ) allows clearing of air from the tank, maintaining said over-pressure at a desired value.
