The purpose of the study was to determine biotechnological dimensional characteristics forming external and internal structure of the grain for the development of design parameters of a new rotary-blade peeling machine. The results of the analysis of the technologies and equipment for separation and collection of individual fractions from the grain structure were presented. It was established that due to high demand and continuous growth of world prices for oil obtained from the embryo, new technologies and equipment for separating and collecting the embryo during wheat husking were being actively developed in foreign countries and in Russia, at the same time, the developed designs of the working bodies of peeling use an abrasive tool, which leads to the increase in waste from the peeling process. To develop new equipment for step-by-step peeling without using abrasive peeling organs , experimental studies were performed to determine the thickness of fruit and seed coats, aleurone and subaleiron layers, and the size of the embryo. The results of collected experimental material were processed by statistical methods and theoretical functions of normal distribution law were obtained, and the tightness of the connection between experimental and theoretical parameters was checked by Pearson's Chi-square. The results of processing statistical experimental material allowed to obtain the average values and mean square deviations in the grain diameter in central part, in the grain length, the size of the thickness of the fruit and seed shells, aleurone and subaleiron layers and the size of the embryo , which allowed taking into account average value of the studied parameter and a mean square deviation, design data in the form of working gaps for a grain peeling by new technology.
