PEELING PROCESS OF DURUM WHEAT IN THE PRODUCTION OF UNCRUSHED CEREALS AND EVALUATION OF ITS EFFICIENCY
Introduction.The tendency to use durum wheat to produce uncrushed cereals actualizes the problem of ensuring maximum efficiency of the technological process. The scientific task is to optimize the process of peeling durum wheat when receiving uncrushed cereals and establishing criteria for evaluating its effectiveness. Materials and methods. Varieties of hard types of wheat Toles, Vladlen, Valenta harvested in 2018 were used in the study. Laboratory experiment was carried out by means of УШЗ-1peeling machine. Grain was subjected to preliminary hydrothermal processing. Results. The dynamics of changes in the yield of the kernel, crushed kernel and meal during the peeling process is virtually the same for all the varieties under study. An intensive increment in the yield of the crushed kernel and meal is observed when the peeling coefficient reaches 65-75 %, while the kernel integrity coefficient increases on average to 0,85-0,87. The most effective process is achieved when ash reduction degree amounts to 0,4-0,5 %. Conclusions. The specified criteria can be recommended for evaluating the effectiveness and controlling the technological process of peeling durum grain in the production of uncrushed cereals, with their values in the indicated ranges being optimal, which can significantly increase the yield of the finished products.
