TECHNOLOGICAL CONTROL OF HUMIDITY IN THE PROCESS OF HYDROTHERMAL PROCESSING OF GRAIN

Abstract

The paper considers information and the concept of humidity, as well as its role in regulation and management, where the role of humidity is an indispensable component in all stages of the technological process of grain processing. The primary transducers of humidity converted into an electrical quantity are analyzed, the basis of which is a capacitive sensor-capacitor, in the electric field of which there is a certain volume of grain, an approximation of a real physical object by its electrical model. To select a method, indirect methods based on measuring the humidity of the dielectric constant of the material under study are analyzed, which is based on the dielcometric method, the results present the developed functional scheme of the measuring unit of grain moisture sensors, and the question of designing and building devices for monitoring the moisture content of grain and granular materials based on this method is recommended, metrological characteristics are given A prototype of a grain moisture meter based on the dielcometric method, as well as its advantages and disadvantages
