Patent ID: 8869540

Claim:
A machine for producing liquid and semi-liquid food products with a continuous cycle comprising: a containment tank for directly containing basic liquid or semi-liquid food products comprising an outfeed hole; a whipping and freezing cylinder having an infeed for the basic food products, the infeed positioned below the containment tank and in communication with the outfeed hole, the whipping and freezing cylinder comprising a mixer for whipping and freezing of the basic food products and for obtaining an end product; a pump comprising an intake duct for drawing the basic food products from the containment tank and a delivery duct for transferring the drawn products towards the whipping and freezing cylinder infeed; a flexible delivery pipe positioned in the containment tank and connecting the pump delivery duct to the outfeed hole; wherein the outfeed hole includes a tubular portion which extends through the whipping and freezing infeed such that the connection of the pump delivery duct to the outfeed hole by the flexible delivery pipe places the pump delivery duct in communication with the whipping and freezing cylinder; a fluid-proof seal engaging between the flexible delivery pipe and the outfeed hole tubular portion to isolate the basic liquid or semi-liquid food products in the containment tank from the whipping and freezing cylinder except via the pump and flexible delivery pipe; wherein the flexible delivery pipe allows a fluid tight connection between the pump delivery duct and the outfeed hole within a range of variable positioning of the pump delivery duct with respect to the outfeed hole.
