Patent ID: 7644656

Claim:
Improved liquefier of the type based on a drive unit that rotates a grater disc, which, upon receiving a piece of fruit or vegetable from a feed hole, and after grating the piece of fruit or vegetable, forces pulp towards an inverted frustoconical filter having a lower and smaller base which is occupied by the grater disc and an upper base which remains open, such that, due to effects of centrifugal force and an inclination of walls of the filter, the pulp is ejected upwards and is directed by the geometry of a lid sealing the liquefier to a waste bin, whereas, under the action of the centrifugal force, juice falls through the filter and is collected and ducted to a juice outlet spout, comprising: a rotating “L”-shaped tubular piece inserted in the juice outlet spout for preventing dripping when the liquefier is not producing juice; a female drum for supporting the grater disk and having a concentric aperture defined therethrough; a male drum for engaging a motor of the drive unit and adapted to be received in the aperture defined through the female drum; a plurality of strips of non-stick material disposed in a space between surfaces of the male and female drums; a folding handle-like piece having claw-like ends that engage corresponding T-shaped heads on the liquefier for sealing the lid during liquefying; a push piston adapted to be received in the feed hole and having a cavity with an opening adapted to receive another push piston therein; and wherein the waste bin includes sidewall with a recess corresponding to a ventilation grill on the liquefier for redirecting airflow output from the ventilation grill.
