Yaschuk A. Substantiation of parameters of flax oilseed dryer

The object of study is a drying process of heap of oil flax seed. The aim of the research is the choice of rational regimes and substantiation of parameters of the dryer to reduce energy consumption for the process of drying of oil seed heap. Theoretical studies carried out using methods based on the basic principles of the theory of drying, mechanical and mathematical modeling, numerical solution of problems with a computer, classical mechanics. The results of experimental studies processed using elements of the theory of probability and mathematical statistics. The rational constructional and kinematic parameters of spiral activators in the drying chamber of the oil seed flax dryer were theoretically and experimentally substantiated to intensify the process of drying the material by its loosening and mixing. The dependencies, describing the kinetics of drying linseed oil, the moving of a particle of material on the spiral rough surface of activator in the environment of material and the ventilation of layer of bulk material in the cylindrical drying chamber were submitted. The novelty of technical solutions protected by two patents of Ukraine. The results of the research and developed documentation of the oil seed dryer were introduced to the agricultural equipment plant PJSC "Kovelsilmash." A prototype passed industrial tests in Volyn State Agricultural Experimental Station of the Institute of Agriculture of Western Polissya of National Academy of Agrarian Sciences of Ukraine (Rokyni, Volyn region).
