This article discusses the possibility of mathematical modeling andoptimization of parameters of the process of buckwheat. As a result of the research,a regression equation was obtained, which allows to predict the optimal extrusionparameters of buckwheat and reduce the number of experiments. Extrusionprocessing is one of the most attractive methods of processing grain crops to obtainsemi-finished products. The efficiency and effectiveness of the use of this equationis proved in laboratory conditions. The influence of all factors was studied duringthe extrusion of buckwheat grain, pressure, temperature, processing time andhumidity of the feedstock on the yield of blasted cereal, the content of watersoluble substances, the swelling and density of the extruded raw material. Amathematical model of the process of extrusion of buckwheat grain made itpossible to find rational process parameters allowing to obtain extrudates with highconsumer properties.

The article describes the developed radiometer for Express measurement of alpha radiation of radioactive elements based on a large-diameter silicon detector. The main element of the PPD detector is made using computer mathematical modeling of all stages of the technological process of manufacturing detectors, taking into account at each stage the degree of influence of the properties of the initial silicon on the electrophysical and radiometric characteristics of the detector. Detectors are manufactured for certain types of devices. The developed radiometer is designed to measure alpha radiation of natural isotopes (238U, 234U, 232Th, 226Ra, 222Rn, 218Po, 214Bi, etc.) in various environments. It also shows the principle of operation of the device, provides a block diagram of the measuring complex, describes the electronic components of the radiometer, as well as the block diagram. Signal transformations (spectrum transfer, filtering, accumulation) are implemented programmatically on the basis of a digital processing module. The device can detect the presence of specific elements in various environments, as well as protect people from the harmful effects of adverse radiation and can be used both in the field and stationary.

Main Component

In this paper we consider the structural and technological process of the combine used in the process of separate harvesting of grain crops, as well as a number of its parameters. Among the main units of the combine, we allocate a conveyor and devices for removing beveled stems from under the wheels of the vehicle. The principle of operation of the conveyor at different phases of the Reaper and especially the removal of cut stems from under the wheels of the vehicle during operation of the Reaper. The results of theoretical studies on the establishment of the optimal design of the parameters of the belt conveyor are presented, the ranges of their optimal values are considered and determined. Studies on the establishment of optimal parameters of the screw divider in the Reaper, which is the main component of the device for removal of beveled stems, are presented. Taking into account the optimal design and mode of operation of the screw divider, the correct work is provided to remove the cut stems from under the wheels of the harvester.
