| Popis: | Analysis of researches on the study of the material particle movement on the vibrating surface of the container machine intended for seed drying in the infrared field is carried out. Comparison of traditional devices for dehydration of raw materials with energy supply of infrared irradiation is performed. It is shown that current tendencies of the development of heat and mass transfer equipment are connected with the use of electromagnetic generators of infrared energy. The purpose of the work is to study the process of movement of sunflower seeds on a vibrating tray dryer. To achieve this goal, a dynamic scheme of the vibrating tray has been proposed and theoretical and experimental studies of the process of grain movement have been carried out. It has been established that when the speed of drive electric motors increases from 950 to 970 rotations per minute, the speed of vibro-transportation increases as well, but when reaching a certain value of speed, under a further increase in speed, the speed of vibro-transportation decreases. Experimental studies have allowed to specify the design parameters of vibrating trays and select rational parameters of the technological process of drying, namely the oscillation frequency of the vibrating tray, which is f = 100 s–1. |
