Abstract
The food refiner comprises a sieve, provided with an inlet for a produce to be processed and an outlet for a waste product, at a center of which a rotor extends from the inlet to the outlet and bears a plurality of spatulas which interact with an internal surface of the sieve, and a casing which surrounds the sieve and which is provided with an outlet mouth for extracted product. The spatulas can be oriented contemporaneously and with different orientations with respect to an axial direction of the rotor which, for this purpose, comprises an external jacket and an internal jacket which can, on command, translate relatively to each other so as to cause a positioning of the spatulas, made possible by a guided rotatable coupling of the spatulas in relation to the rotor.
Claims18
A variable-trim food refiner, of a type comprising:
- a sieve, provided with an inlet for a produce to be processed and an outlet for a waste product, at a centre of which a rotor extends from the inlet to the outlet, the rotor being rotatable on command and bearing a plurality of spatulas, an end of each spatula of the plurality of spatulas being very close to an internal surface of the sieve;
- a casing, which surrounds the sieve and which is provided with an outlet mouth for extracted product;
- wherein the spatulas are movable with respect to an axial direction of the rotor and rotatable on a radially directed axis of the spatulas with respect to an axial direction plane of the rotor.
A variable-trim food refiner, of a type comprising:
- a sieve, provided with an inlet for a produce to be processed and an outlet for a waste product, at a centre of which a rotor extends from the inlet to the outlet, the rotor being rotatable on command and bearing a plurality of spatulas, an end of each spatula of the plurality of spatulas being very close to an internal surface of the sieve;
- a casing, which surrounds the sieve and which is provided with an outlet mouth for extracted product;
- wherein the spatulas are orientable with respect to an axial direction of the rotor;
- wherein the rotor comprises an external jacket exhibiting a plurality of slots and a plurality of guide holes, and an internal jacket which is solid in rotation with the external jacket and which is provided with a plurality of through-holes, each of which plurality of through-holes is located at a position corresponding to a position of a slot;
- the external jacket and the internal jacket being able, on command, to make relative axial translations;
- each spatula of the plurality of spatulas comprising, at an end thereof connected to the rotor, a rotation pivot inserted in a slot of the plurality of slots and fixed rotatably idle in an underlying through-hole of the plurality of through-holes;
- each spatula of the plurality of spatulas further comprising a guide pivot which is fixed with respect to the spatula of the plurality of spatulas and which inserts slidingly into a guide hole of the plurality of guide holes and can be guided thereby;
- further comprising means for commandably causing an axial relative translation of the internal jacket and the external jacket of the rotor.
