Resource-saving grain husking technology

The paper presents technical solutions aimed at increasing the efficiency of the technological process of grain seed husking by the method of step-by-step removal of fruit and seed coats. For grain seeds, it is not required to perform calibration. The author resource-saving technology and new equipment are described. They involve a multi-stage effect on grain seeds by changing the working technological gap created by the lined elastic material of the inner surface of the body and rotating movable husking hemispheres lined with elastic material, combined into one unit of patented technological equipment. A comparison of the developed resource-saving technology with the technology used for the active action of an abrasive tool by stripping fruit and seed casings is carried out. Key technical solutions were identified. They increase the production efficiency of using a multi-stage process of husking grain seeds by 14%, reduce energy consumption by reducing the amount of equipment used for calibrating seeds by 15%, reduce the amount of waste in the form of bran with a multi-stage resource-saving effect of lined elastic materials for fruit and seed casings by 18%, and increase the yield of uncrushed hulled grain to 91%. The technical devices developed are intended for implementation schemes for processing grain seeds by micro and small farms. The use of the resource-saving technology reduces the cost of grain seed husking by 8-10%, depending on the variety of grain seeds.
