The analysis of the use of modern screw separators for the dehydration of liquid organic substrates, both agroindustrial complex and other sectors of the economy is done. The technological scheme is proposed and the design of a screw separator for dehydration of an grain distillery spent wash is developed. The main feature of the proposed screw-press separator is a two-stage process of dehydration of the input substrate. The liquid substrate solution enters the first area of the screw separator, where the liquid fraction - fugate is removed through the openings of the pre-spin cylinder, and the solid fraction - the cake enters the second zone. In the second zone, the pre-pressed cake serves as a filter of fine purification through which a fugate is released through the pressure, which was released from the first zone and contains many solids in the liquid phase, such as yeast sediment in the bard . In this way, the fugate is being purified and exits through the openings of the final spin cylinder. As a result of the research and development work, a new screw separator was created. The use of a two-stage system of dehydration of liquid substrates in a screw separator will significantly reduce the solids content in the liquid phase.
