JUSTIFICATION OF THE DESIGN SCHEME OF THE INSTALLATION FOR PROCESSING GRANULAR MATERIAL WITH INFRARED RADIATION

Abstract

The article describes technologies for post-harvest processing of grain, the main components of which are interconnected cleaning and drying technologies. The technology of post-harvest processing of grain is carried out to a greater or lesser extent during the entire period of storage of grain of different purpose, state of clogging and moisture, differing in structural and mechanical properties and chemical composition, etc. Post-harvest processing of grain can be singled out among the main priority operations of this industry. The strategic importance of the development of this industry became the basis for the activity of one of the structural subdivisions of the Educational, Scientific and Production Complex (NNVK) «All-Ukrainian Scientific and Educational Consortium» - Scientific and Research Farm «Agronomichne». The article discusses the design schemes of devices for heat treatment of grain, micronizers, infrared dryers in which heat treatment of grain is carried out with the help of infrared radiation; their principle of operation, advantages and disadvantages are also studied. On the basis of the results of this study, an installation for processing granular material with infrared radiation was developed. The classification of grain processing technologies of cereal and leguminous crops has been carried out. The problems of minimizing thermal energy losses and improving the quality of material processing are solved by changing the design and increasing the efficiency of using the heat of infrared radiation due to the return of the heat of the cooling radiators of the material being processed. In this scientific work, the task set is solved by the fact that the heat taken from the air by the emitters (lamps or heating elements) is supplied by jets to the irradiating material and by the creation of a "running wave" on the surface of the conveyor belt, which is deformed, which ensures a pseudo-suspended state of the material due to the application of interaction ferromagnetic elements (rods, columns) placed on the tape with magnets placed under the tape at a certain distance from each other.
