ABSTRACT:
In a continuous press of a screw blade type, a driving shaft is rotatably secured to a frame by means of thrust bearings at both ends of the driving shaft, a screw drum having an increasing diameter towards center is disposed around the driving shaft to rotate therewith, a pair of screw blades are helically arranged around the screw drum symmetrically with respect to the center of screw drum, and an outer drum having a number of small filtering holes is arranged around the screw blades. A pair of inlets for introducing raw materials to be pressed are provided at both ends of the outer drum and an outlet from which the pressed raw materials are discharged is also provided in the outer drum at its center. At the outlet a pair of cone-shaped plates are arranged movably in an axial direction of the press and these plates are resiliently pressed towards each other. The pressure applied to the cake is automatically maintained constant due to the axial movement of the plates.
