The efficiency of post-harvest processing of grain mixtures determines the quality and safety of food grain and seed material. Drum separators with cylindrical sieves are common machines used for pre-cleaning of grain heaps with high humidity and clogging. The problem with the use of drum separators with horizontally located cylindrical sieves is their insufficient productivity due to the low contact area of the grain material with the surface of the sieve. The analysis of design features of this type of machines has been carried out in the work, the results of researches of increase of efficiency of work of drum separators have been determined.
The analysis allowed to discover ways of increasing the efficiency of the process of cleaning grain materials on cylindrical sieves which have been brought to a common classification.
It has been established that changing the location of elongated holes relative to the axis of rotation is a promising way to improve the design of the sieves. For further research in this area, the parameters of the process of cleaning grain mixtures are identified, which are significant and affect the technological efficiency.
