THE INVENTION DISLOSES AN APPARATUS FOR EXTRACTION OF FIBRES FROM EMPTY PALM FRUIT OIL BUNCHES. THE APPARATUS CONSISTS OF A PAIR OF ROTATABLE ROLLERS (10) MOUNTED TO ROTATE IN OPPOSITE ROTATIONAL DIRECTIONS, SAID ROLLERS INCLUDE A PLURALITY OF HELICALLY DISPOSED VANES (32) WITH A VOID (31) ALONG A TERMINAL EDGE PORTION OF THE VANES. AT LEAST ONE SIEVE PLATE (19) IS DISPOSED BELOW THE PAIR OF ROLLERS AND A SUPPORT RIB CAGE (18) IS DISPOSED BELOW THE SIEVE PLATE (19). AT LEAST ONE CUTTER BLADE (28) IS MOUNTED IN MANNER SUCH THAT THE CUTTING EDGE OF THE CUTTER BLADE EXTENDS INTO THE VOIDS (31) OF THE HELICALLY DISPOSED VANES (32). THE CUTTER BLADE (28) IS MOUNTED ON AN ENCLOSURE PLATE (26). THE PAIR OF ROTATABLE ROLLERS IS ENCLOSED IN A CHAMBER FORMED BY TWO BOXED CONTAINER SIDE PANELS (22), THE SUPPORT RIB CAGE (20), THE ENCLOSURE PLATE (26), A TOP COVER PLATE (40) WITH A HOPPER (24) MOUNTED ONTO THE TOP COVER (40) PLATE AND A SIDE WALL OF THE CHAMBER (34). THE EMPTY FRUIT BUNCH (EFB) IS INTRODUCED INTO THE HOPPER AND IS CUT INTO SMALLER PORTIONS BY THE HELICAL VANES AS IT IS URGED FORWARD ALONG THE PAIR OF ROLLERS, AND IS FURTHER CUT INTO SHORTER LENGTHS BY THE CUTTER BLADE. CUT FIBRES ARE DISPOSED OFF AFTER BEING EXTRUDED FROM THE ENCLOSURE PLATE. PALM OIL SQUEEZED FROM THE EMPTY FRUIT BUNCH WHEN IT IS URGED FORWARD ALONG THE PAIR OF ROLLERS (10) IS SEPARATED FROM CUT FIBRES BY THE SIEVE PLATE (18).
