Decrease of grain losses appears one of the most important problems of agricultural producers. In the conditions of the Republic of Belarus total losses of grain compose more than 10% (0.7-0.9 million tons) due to seed falling, pest injury and weed impurity; 5-7% of harvest is lost on barn-floors due to defective grain cleaning and storage. After-harvesting grain processing is one of the most important and resource-consumptive technological process, and preliminary cleaning of grain allows declining production losses and prolonging storage terms. The article reflects the problem of reducing of post-harvest losses of grain, its storage and qualitative cleaning. Technical and operational characteristics of grain cleaning machines available on the farms of the country and analysis of structural and technological features and shortcomings of their work are given; innovation home-made grain cleaning equipment is suggested. The schemes and photos of the machines are presented. The main advantages of the proposed new domestic equipment are shown.
