The article is devoted to the current problem of improving the efficiency of mechanized grain processing by reducing its mechanical damage during the operation of gravity transporting devices. It was found that as a result of high-speed movement of grain material with a low flow density, the number of impacts of grains on each other and on the walls of the gravity device increases, which increases the probability of damage to individual grains. To reduce the speed of the grain flow, a variant of a portioned grain pipeline with gravity-driven flaps is proposed. Calculations and experimental studies show that the speed of grain flow can be reduced to 2.5 m/s, which significantly reduces the damaging ability of the gravity device with constant performance.
