摘要：
FIELD: technological processes.SUBSTANCE: invention relates to automation of technological processes of treatment of distillery stillage being a by-product of alcohol production and may be used to automate the process in food, fodder and other industries. Mechanical wringing of distillery stillage, its coarse and fine separation accordingly in two parallel separators and fine filters is carried out, and each of them periodically operates in the separation mode with cake and filtrate discharge and in the mode of counterflow water regeneration of filtering elements. The produced filtrate downstream the fine filter operating in the separation mode is sent into an accumulating tank. The filtrate is evaporated in the vacuum-evaporating apparatus to produce a condensed solution, which is sent to a spray dryer to produce a powdery product. Underpressure in the vacuum apparatus is developed with the help of a steam jet ejector installation, comprising a steam generator, an ejector, a condenser, a condensate collector and a pump operating in a closed thermodynamic cycle. The working steam produced in the steam generator is divided into two parts, one of which is sent to a heating chamber of the vacuum-evaporating apparatus, and the other one - into the ejector nozzle. Ejected vapours from the vacuum apparatus create underpressure of 0.3-0.5 atm. in it. The mixture of the spent working and ejected vapours is sent to the condenser, in which due to recuperative heat exchange they heat air with its subsequent supply into the spray dryer, from which the spent air is discharged into the heat-exchanger-recuperator, where its temperature is reduced to the dew point, and drop liquid contained in it is condensed as moisture evaporated from the product on the cooling surface of the heat-exchanger-evaporator, and then again sent first into the condenser and further into the spray dryer with creation of the closed cycle. The condensate produced downstream the heat-exchanger-recuperator t
