Claims10
A universal screw press comprising
- (a) an inlet unit;
- (b) a driving gear;
- (c) a modular worm shaft;
- (d) an outlet unit;
- and
- (e) a modular housing,
- wherein said modular housing comprises a first perforated housing unit provided with perforations the sizes of which are variable during operation, wherein the variably sized perforations of said first perforated housing unit are formed by a first and a second element of said first perforated housing unit, said first and second elements being displaceable in relation to each other during operation, wherein said first element of said first perforated housing unit is a perforated outer tube, said second element of said first perforated housing unit is a perforated inner tube, said inner and outer tubes have a common longitudinal axis are in contact and are rotatable with respect to one another about said longitudinal axis.
