Development of a plant for peeling rapeseed in the electromagnetic field of ultrahigh frequency

Abstract

Currently, domestic industry uses imported raw materials. At the same time, supplies of rapeseed oil for export as raw materials account for about 80% of the production volumes. Therefore, import substitution of rapeseed oil due to an increase in its own production and a significant increase in the efficiency of processing technology with improved quality characteristics, the development of innovative technology and technical means to improve the quality of peeling of rapeseed is relevant. Depending on the grain structure, one of three methods of peeling is used: compression and shear, multiple or single blow, by abrasion of the shells. The rapeseed kernel has a fragile structure, so peeling with a multiple blow is irrational. Two requirements are imposed on the rape seed peeling process: high-quality separation of husk from the kernel and preservation of the integrity of the kernel. The article describes the developed design of the installation for peeling rape in an electromagnetic field, which allows the peeling process to be carried out at low operating costs. The process of peeling rape is possible by hydromechanical destruction and abrasion of husks on rotating abrasive disks and mutual friction of grains in the EMF microwave, followed by removal of the shells by blowing air through a hollow dielectric shaft with holes and a perforated cylindrical resonator. The article also describes the technological process of rape peeling and conducted a feasibility study on the implementation of the proposed installation. The economic effect of the use of a microwave installation for rape peeling is 124 thousand rubles/month with the volume of output 38.5 tons/month, profitability will increase by 3.7%.
