Development of a Device for Primary Purification of Mung Bean Grain from Pods and Optimization of Its Main Design Dimensions and Operating Modes

Abstract

It is important to create a technically and technologically improved device that reduces the damage to the mung during the process of removing the pods from the currently cultivated mung grain. Therefore, it is necessary to develop the design of the device, to justify its parameters and operating modes, for the complete separation and preliminary cleaning of mung beans without damaging them. The article presents the results of optimization of the main design dimensions and operating modes of the device for separating mung bean from the pods. The results of experimental studies showed that the proposed device has a high degree of completeness in separating mung bean from its pods and a low level of damage, low grain damage and high grain purity, which can be ensured with a sag length of 170 mm, a shaft oscillation number of 300 min-1, the amplitude of the shaft is 11.5 mm, its angle of inclination is 12 degrees. The design of the device for preliminary cleaning of mung grain by separating it from pods has been developed. The scientific significance of the research results is based on the structural dimensions and operating modes, as well as the resulting analytical connections and mathematical models, to ensure the quality of initial cleaning, to separate mung beans from pods completely and without damage, using less energy and resources. can be used to justify the parameters of similar devices. The developed device reduces the consumption of energy and labor during the initial cleaning of mung grain from pods, as well as the loss of grain.
