Grinding and dewatering apparatus of food waste by centrifugation

摘要

A grinding and dewatering apparatus by centrifugation for highly selective differentiated food waste collection includes, in a supporting structure, a hopper introducing waste-products into a grinding chamber and subsequently into a centrifuge having an inner body and an outer body with a finely perforated, coaxial side wall, a deceleration chamber of the filtered water, a motor driving a grinding unit and the centrifuge, wherein the motor integrally activates both the grinding unit and the centrifuge and overlies both, and a discharge for evacuation of the ground waste-products. Both the grinding unit and the inner and outer bodies of the centrifuge are positioned in a deceleration chamber and are arranged integrally with a rotating disc, and the discharge is a movable discharge, that can be selectively positioned below openings, situated in a flanged extension arranged below for closing the centrifuge for the evacuation of the ground waste-products into a collection basket.

主权项

1. A grinding and dewatering apparatus by centrifugation for highly selective differentiated food waste collection comprising, in a supporting structure (10):
a hopper (11) for introduction of waste-products into a grinding chamber (12) and subsequently into a centrifuge (22), said centrifuge comprising an inner body (23) and an outer body (24) with a finely perforated side wall coaxial to the inner and outer bodies; a deceleration chamber (26) of filtered water; a motor (15) driving a grinding unit (21), said centrifuge (22) being integral with the grinding unit, wherein said motor (15) integrally activates both the grinding unit (21) and said centrifuge (22) and is in a position overlying both (21, 22); a discharge for evacuation of the ground waste-products, wherein both said grinding unit (21) and said inner and outer bodies (23, 24) of said centrifuge (22) are positioned in said deceleration chamber (26) and are arranged integrally with a rotating disc (18) disposed between said grinding unit and said inner and outer bodies, said rotating disc being turned by the motor and projecting said waste-products into the grinding unit, and wherein said discharge is a movable discharge (27) configured to be selectively positioned below openings (29), situated in a flanged extension (25) that is arranged below said centrifuge and closes said centrifuge (22), said opening evacuating the ground waste-products into a collection basket (34); and a doctor blade (38) configured to be be selectively moved in engagement with said finely perforated side wall of the outer body (24) of the centrifuge (22) for detaching the centrifuged waste-products.
