FIELD: fat-and- oil industry. SUBSTANCE: apparatus has cylindroconical casing with raw oil plant material processing unit having housing mounted within casing in vertical position and provided with powered auger-type shaft. Device for partial removal of husk and contaminants from raw oil plant material to be processed is mounted on shaft drive. Two perforated closed shells are positioned within cylindroconical casing, which is mounted within boxlike carcass frame so that channels with drying agent supply and used drying agent discharge branch pipes are defined. Conical part of casing has perforated portion for directing husk and contaminants. Used drying agent discharge branch pipe is positioned in lower part of cylindroconical casing adjacent to perforated portion. Drying agent supply branch pipe is formed as annular flare with conical part and is positioned in casing so that it embraces a portion of vertical housing at location adjacent to husk and contaminant removal device. Drying agent supply branch pipe is communicated with annular drying agent heating channel. EFFECT: reduced power consumption, reduced material usage, convenient operation, improved quality of processed product by efficiency removal of husk and contaminants. 2 cl, 1 dwg
