The aim of the research is to determine the effectiveness of ergot isolation and to estimate grain losses in waste when the cereal material is immersed in the stream material in water and an aqueous solution of salt of different densities ρzh from the specific grain load gsp. Practical experiments were carried out by feeding grain material of winter rye of Falenskaya 4 variety with a moisture content of 14% from a height of h = 60∙10-3 m into water and an aqueous solution of sodium chloride (NaCl) with a density of 1030, 1060, 1090, 1120, 1150 and 1180 kg/m3. The variation of the specific grain load gsp was carried out according to the values of 0.674; 1.469; 2,871; 4.449 and 7.221 kg/(s∙m), which corresponded to the opening of the outlet window of the bunker of the experimental setup 10.0; 15.0; 20.0; 25.0 and 30.0∙10-3 m. The temperature of ambient air, water and an aqueous solution of salt was 200C. It has been established that the density ρzh of an aqueous salt solution has a greater influence on the result of the technological process than the specific grain load gsp. At a density ρzh of the aqueous solution of the salt of 1150 kg/m3, there is a 100% emergence of ergot sclerotia on the surface of the solution, and the losses of the PZ grain to the waste do not exceed 2,52%, which corresponds to the agrotechnical requirements for the final grain cleaning machines.
