“…Therefore, the volume of grain that has gone through the unloading hopper outlet from its left section exceeds that from the right section by 0.0011 m 3 . The results of experimental studies carried out several times were in good correlation with our theoretical estimates according to Equation (15). Therefore, the grain flow in the left section of a convectivemicrowave processing zone has a greater rate compared with the right section.…”

“…This mainly applies to the application of fluidized bed methods [13]. Grain dryers with alternating direction of blowing through grain layers [14], as well as those with grain recirculation [15] are also widely used. Among ecologically friendly grain drying methods, that of processing in convectivemicrowave units is worthy of mention [16,17].…”

This article describes the influence of dynamic bridging in the unloading of a hopper at a processing plant on the grain flow homogeneity in a convective-microwave zone. In accordance with calculation methods for unloading hoppers, the parameters of the hopper unit and those of the outlet hole insuring that grain flows without static bridging formation is defined. It was found that moisture content fluctuations do not affect the process of grain transport. The equation for dynamic bridging rise depending on its position on the vertical axis of the unloading hopper has been deduced that enables the definition of the inhomogeneity of grain flow from its outlet hole. Calculations show that a certain inhomogeneity occurred between the right and the left parts of the unloading hopper in relation to its vertical axis in the course of grain discharging. This effect underlies the inhomogeneity of grain processing and reduction of its effectiveness in convective-microwave zones. An experimental model of unloading the hopper has been manufactured in order to perform investigational studies. The results of studies have completely confirmed the hypotheses. It has been found that dynamic bridge formation in unloading of the hopper results in the inhomogeneity of grain flow in convective-microwave zone.

“…That is why various methods designed to reduce the energy consumed for drying, including the application of infrared radiation [9], ozone-air mixtures as drying agents [10], and processing plants with ultrasonic grain drying effect [11] are applied. Grain dryers with alternating blow-through directions in the grain layer [12] and those with grain recycling are also widely used [13]. One of the environmentally safe grain-drying methods is treatment in convective-microwave processing plants [14,15].…”

The microwave field is used for drying and disinfecting grains during the pre-sowing seed treatment. The use of a microwave field in these installations leads to an increase in their productivity and a decrease in the energy consumed by them. In grain dryers, where the grain moves in a dense layer without being loosened, one of the challenges in using microwave fields is ensuring sufficient uniformity of the field distribution. In this article, waveguide design options that introduce microwave radiation into the grain layer are discussed. The objective of this study was to use application software to find the optimum type of transmitter from the three options presented. A mathematical simulation of the electromagnetic field distribution was performed with the use of CST Microwave Studio software 2019 in order to evaluate and compare horn-type, rectangular, and semicircular waveguides. The data on the standing wave ratio and radiation efficiency of these types of waveguides have been reported. The specific features of the microwave electromagnetic field distribution and radiation power in the output of these waveguides have been described. The results of mathematical simulations revealed that semicircular waveguides with slot-type radiators are preferable for processing dense grain layers.
