stored in the cyclone and are discharged therefrom through an airlock 100 placed at the end of the cyclone cone 101 fibers evacuated from cyclone 96 are intended for use as biomass or boiler fuel or may be used as organic material for composting processes on the other hand the nuts by being more dense than the fibers are deposited on the lower part of the air separation column where there is a circular outlet nozzle towards the nut polishing drum of fig1 which is a rotating equipment that is coupled in the lower part of the air column through an attachment nozzle 103 the main body 104 of said polishing drum is cylindrical and inside there is a screw 105 which extracts nuts from the bottom of the air separation column and moves them along the body of the polishing drum in which by rotation and friction with each other they are polished removing small fibers that facilitate further processing on the other hand in the external body of the nut polishing drum a gear 106 is located which is actuated by a chain 107 which in turn is connected by another pinion 108 to a gearmotor 109 thereby producing the rotational movement of the polishing drum said polishing drum is supported on metal pedestals 110 nuts are discharged from the polishing drum by its outlet on the other hand fibers arising from the nuts are discharged through the holes of the circular mesh 111 that form the body of the drum finally the system for palm oil extraction disclosed in the present invention comprises a steam condenser fig1 which is a vertical cylindrical vessel arranged to receive the vapor discharge.
