The search for the optimal variant of the structural ar-rangement of flat-screen separators by centrifugal-air sepa-rators with annular pneumatic separation ducts is a promis-ing direction in the development of new equipment. This will significantly improve the technological performance of grain cleaning plants. It may be considered a promising direction for such research. Therefore, it is necessary to look for new options for the layout of grain cleaning ma-chines to increase their technological efficiency. Several variants of technological schemes for the operation of ex-isting flat-sieve separators with a centrifugal-air separator with an annular pneumatic separation ducts are proposed. The technological process of the modernized grain clean-ing plant based on the A1-BIS-100 plantis described. The main parameters of the gravity transporting device are de-termined; they fully ensure the operability of the modern-ized plant.
