Description

 The object of research is the process of drying agricultural raw materials (walnuts). The purpose of the work is to increase the efficiency of mass and heat transfer processes of agricultural production (increasing productivity, reducing specific energy consumption, while preserving or improving the quality of finished products) by optimizing the operating modes of energy-efficient equipment for drying agricultural raw materials. Research methods: numerical modeling using the basic principles of theories of classical mechanics, gas dynamics, probability, elasticity, models of discrete elements, multiphase interaction, Lagrangian multiphase. Modeling and processing of research results was carried out using STAR-CCM+ and Mathematica software packages. The constructive and technological scheme of the convective dryer of walnuts, which is made in the form of a mixer with a vertical screw working body with a bottom injection of a warm air flow, has been developed and substantiated. Using the Star CCM+ software package, the technological process of drying was simulated in the developed convective dryer. Visualization of the process of redistribution (mixing) of walnut fruits in the drying chamber under the action of the screw working body and the distribution of air flow speed and temperature in the drying chamber of the convective dryer was obtained. The SGK-4 "TIRAS" convective dryer was developed, manufactured and production tested. The obtained results have significant economic significance for the development of the agro-industrial complex, as well as the intensification of mass and heat exchange processes, in particular the process of drying agricultural products.
