Abstract

In the presented materials, a system of principles and approaches for studying processes of microwave-convective grain treatment is discussed. The essence of this research is described starting from the initial phase of designing structural diagrams of technological processes. Based on the explicitly-defined process target, a functional-physical analysis has been performed that made it possible to specify the most essential factors of process. The morphological analysis of the processes was carried out in several stages. At each stage, the specification of the goal and excluded variants of factors that at this stage, the development is impractical to implement. It is advisable to carry out a check of the effectiveness of the options selected from the morphological table using modeling. To this end, developed a mathematical and computer models of the process. The results of modeling the drying of grain in the microwave - convective zone confirmed the feasibility and efficiency of using the obtained model.

Research Method

Methodology, in its practical sense, is a system of principles and approaches for research activities that have to be adhered by researchers in the course of obtaining and development of knowledge, in the frames of a specified problem (Novikov, & Novikov, 2013; Lukashevich, 2001, Ruzavin, 1975). The following system of principles and operation sequence was applied in the course of studying the process of microwave-convective treatment of grain:

  • 1.

    Development of process block diagram.
