Abstract
Technical solutions are presented in the article aimed at improving the efficiency of the technological process of production for vegetable oil and obtaining feed additives for farm animals and poultry from the spring rapeseed, cultivated in the Krasnoyarsk Territory with a high oil content of 38-40%. The authors describe a resource-saving technology that provides for two-stage pressing of oilseed raw materials and obtaining high-quality edible rapeseed oil by two-stage cold pressing of oil from seed cake using screw and piston presses combined in one unit of technological equipment. The developed technology is compared with the double-pressing technology that is used widely in modern processing plants. The key technical solutions are highlighted according to completed analysis, which implementation improves the production efficiency of rapeseed two-stage pressing process for 12%. It also reduces electricity consumption by 8%, increases the yield of rapeseed oil from the cake by reducing the residual oil content in oil cake to 3-5%. The developed technical means are intended for introduction into the production of rapeseed processing scheme for micro - and small agricultural enterprises. It is established that the use of the developed resource-saving technology reduces the cost of rapeseed oil production in comparison with existing technologies for processing oilseeds up to 6-8%, depending on the oil content of the seeds.
