Study of selective heating of grain and insects in a microwave field

Abstract

The paper presents the results of study dedicated to selectivity of microwave field heating due to different material sensitivity of grain and insects to dielectric heating. Microwave heating selectivity is prospective for using the electrical technology in biological technologies, agricultural industry, medicine and other branches of national economy. The interface of several sciences opens promising trends of new researches that have vast potential for manufacturing application. Preliminary research revealed the necessity to analyze the efficiency of selective heating. The author found out  that  the  efficiency  of  selective  heating  is  associated  with  dielectric  parameters  of  grain  and  insects  that implies that the heating is possible which would be fatal for insect cells, but safe for grain cells. Our work is carried out under the contract “Development of the process line producing high-quality seeds from illiquid grain material” concluded within the framework of the program “The Youth Research and Innovation Competition” organized by the Foundation for Assistance to Small Innovative Enterprises in Science and Technology.
