PROCESS OF PRODUCING OIL FROM OIL-CONTAINING VEGETABLE RAW MATERIAL, PROCESS OF EXTRACTION AND REFINEMENT THEREOF, AND APPARATUSES FOR IMPLEMENTATION THE SAME

摘要

FIELD: fat-and-oil industry. ^ SUBSTANCE: process comprises providing oil-containing vegetable raw material, extracting oil from oil-containing vegetable raw material by way of pressing it and separating oil cake. Extraction of oil from resulting oil cake on extraction installation (which is a part of the invention), wherein two cake deoiling are combined: mixing of cake with extractant used at weight ratio 1:(1.9-2.2) for 10-15 min and final counter-current deoiling on inclined screw extractor to residual content of fat in the cake not higher than 1%. Oil obtained through pressing and extraction is refined using complex refiner consisting of three constituents. The first constituent is high-molecular weight electrolyte or mixture of high-molecular weight electrolytes; the second one is low-molecular weight electrolyte or mixture of low-molecular weight electrolytes; and the third one are organic and/or inorganic peroxides and/or hydroperoxides, taken at weight ratio 1:(25-250):(0.5-2.0), respectively. Refiner is used in amount of 0.2 to 1.5% of the total weight of oil being refined. Mixing of the oil being refined with complex refiner is effected no longer than 30 min at temperature between 0 and 100°C by way of creating spiral trajectory of movement of resulting mixture in a suitable apparatus (which is a part of the invention), after which mixture is settled. ^ EFFECT: achieved high-performance vegetable oil production technology owing to reduced losses of oil in extraction and refining processes. ^ 30 cl, 2 deg, 1 tbl, 5 ex
