Abstract

See full text

Machine (1) used in plants for making puree or fruit juice starting from vegetable or animal food, such as a rough extractor or a fine extractor, comprising a cylindrical body (2) having an inlet (3) for the product to treat, an outlet (4) for part of product that can be used and an outlet (5) for part of product to dispose of. The product put in the cylindrical body (2) of the machine (1) is pushed by centrifugal force of a plurality of blades of an armature (6) to pass through a sieve (7) having holes (8) and having a cylindrical or conic shape. The armature (6) is wheeled by a motor through a shaft (15). The machine (1) has a plurality of holes or nozzles (11) suitable for supplying in the sieve (7) a flow of washing liquid, for example water or diluted juice, in longitudinal direction, or radial direction, with respect to the machine (1), so that the blades of the armature in quick rotation forced it by centrifugal force against the inner surface of the sieve.
