Abstract
The invention provides a helical screw press for processing grape crop in which a filter tube diverges from a predetermined section of its length in downstream direction such that the divergence enables the grapes to be released and prevents formation of an impermeable crust in the filtering tube thereby permitting total pressing and increased flow rate.
