“…The analysis of the design of convective-microwave processing plants concluded that the key element affecting inhomogeneous grain processing is the unloading hopper. Figure 1 shows the convective-microwave processing plant developed by the authors, where the hopper-type principle of grain flow is used [19]. In this technological concept, grain flows downwards by gravity.…”

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.

“…To provide the required parameters applicable to the drying equipment, it is necessary to provide uniform heating of the processed material by the volume of the pipeline. Modern means of computer modelling allow for prototyping and visual representation of the treatment area of the material [5][6][7]. For modelling and further development prior to con-ducting mathematical modelling and sample making equipment, it is necessary to investigate the properties of crops.…”

Significant losses of grain crops at various stages of cultivation, harvesting, post-harvest processing and storage dictate the need to technologies and equipment for these processes. Currently, one of the most promising directions in the field of heat treatment of grain is the use of combined influence methods with the use of electrophysical effects. The purpose of this work is to develop and test a method for measuring the dielectric loss factor by an indirect method, which makes it possible to control the humidity of grain material exposed to microwave. The paper presents the equipment and the design of the experimental installation. The results of the experiment were subjected to regression analysis. The results of experimental studies and dependencies can be used for modelling microwave effects on agricultural bulk materials in electromagnetic modelling software, such as CST Studio.
