Proper and balanced nutrition is the key to a person's physical health, especially in the face of deteriorating environmental conditions and the effects of daily stress caused by the accelerated pace of life in recent years. In this regard, the attention of many researchers and entrepreneurs is focused on the development and implementation in mass production of foods that would fully meet human needs for protein, vitamins, micro-and micronutrients, etc. Recently, ingredients made from non-traditional vegetable raw materials have been used for the production of functional foods. Amaranth belongs to such vegetable raw materials. Amaranth culture has been known since ancient times, used by the ancient Aztecs. The main feature of this culture is the unique chemical composition, which causes an extremely wide range of its use, which is not limited to the food industry. In terms of amino acid composition, amaranth grain protein is close to the composition of an ideal protein. The presence of squalene in amaranth oil makes it possible to use it for the manufacture of medicines and cosmetics. However, despite the prospects for the use of amaranth, producers face difficulties with the characteristics of the grain of this crop. Small grain sizes require careful selection of mode parameters of technological equipment for post-harvest processing. To substantiate the cleaning regimes, a study of the particle size distribution, physical-mechanical and aerodynamic properties of amaranth grain mass has been carried out. Based on the research, it is established that despite the fact that some amaranth species like shchyrytsya” have almost the same grain size and shape, the transgression coefficients calculated according to certain divisibility values can predict the possibility of separating a mixture of freshly harvested amaranth grain and its impurities, in particular from difficult to separate . It is proposed to use a set of sieves with round holes of the following sizes (mm) to separate this mixture: B1 – 1.0…1.1; B2 – 1.0…1.1; B2 – 1.0…1.2; G1 – 0.7…0.9; and elongated holes with dimensions (mm): B1 – (0.8…1.0)×20, B2 – (0.5…0.7)×20, B1 – (0.4…0.6)×20 .
