ABSTRACT:
A pre-filtering apparatus for pre-filtering raw material to be pressed by a continuous screw press having a hopper includes a filtering screen arranged rotatably within the hopper about a shaft, so that the inside space of the hopper is divided into two portions. The raw material is supplied into the one of the two portions which communicates with the continuous screw press. Water, oils and fats extracted by the screen from the raw material are discharged out of the hopper through an outlet pipe provided to the hopper at a position above the shaft.
