Methodology for determining element parameters of equivalent electrical circuit of substitution of stem wall of plant materials

Abstract

Determination of the main directions for increasing the technological component and reducing the thermal effect of the current, identification of the limiting stage of moisture transfer through the stem wall of plant origin are based on the analysis of the process of functioning of the equivalent electrical circuit of substitution of the stem wall of plant material by determining the numerical values of its elements taking into account the biophysical processes in the object under study. The goal is to substantiate the methodology for determining the parameters of resistances of the equivalent electrical circuit of substitution of the stem wall of plant materials. The result of determining the unknowns of the system is to find the values of the elements of the substitution circuit independent of the current frequency. Using these values, the current frequency-dependent parameters of the substitution diagram are determined. The parameters of the substitution diagram elements are functionally dependent on the current frequency. The presented technique allows to determine the parameters of the substitution scheme elements of the stem wall of plant materials and further to estimate the limiting stage of moisture and current transfer through the stem wall and thus to substantiate the presence of non-ideal valve effect of the stem wall depending on the current frequency. Determination of the parameters of the stem wall substitution circuit resistances also makes it possible to formulate the main directions for increasing the technological component of the current and reduce energy consumption for inefficient heating of the treated material.
