PROCEDURE OF UTILISATION OF DISTILLERY DREGS PRODUCED AT PRODUCTION OF ETHYL ALCOHOL Russian patent published in 2010 - IPC C12F3/10 

FIELD: food industry.

SUBSTANCE: procedure consists in dividing hot distillery dregs obtained at production of ethyl alcohol into flows, in concentrating one of them to moisture contents of 70-75% and in production of filtrate, in dividing filtrate into parts; also one of these parts is used for preparation of setting, while another one is used for preparation of solutions of mineral salts. Solution of mineral salt containing nitrogen and/or potassium is added into the third part of filtrate and into the second flow of distillery dregs. Mineral salts containing nitrogen, potassium and phosphorus are added into a concentrated part of distillery dregs. Produced feeding compositions have pH 3.8 - 6.5. One part of feeding compositions is cooled to temperature 25-30°C, while another part is stored under conditions of natural cooling. Upon cooling feeding compositions can be preserved.

EFFECT: facilitating more complete utilisation of distillery dregs, preventing pollution of environment, production of feeding compositions used as fertilisers of directional effect with more regulated activity due to controlled introduction of required components.
