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.
