FIELD: feed industry.
SUBSTANCE: A method for producing a dry extract of a three-part sequence for a feed additive for farm animals and poultry, characterized by the fact that the raw materials are crushed and moistened in an 8-25% water-ethanol solution for 9-13 hours, then transferred to an extractor, filled with 25-65% water-ethanol solution, heated to 25°C and at the first stage extraction is carried out under vacuum, after which the extract is drained, and the mass is re-filled with 25-65% water-ethanol solution, heated to 25°C and extraction is carried out under vacuum, after which the extract is drained, the resulting mass is poured with distilled water in the third stage and extraction is carried out at a modulus of 1 kg-2 liters for 30 minutes at a relative pressure (-0.81)-(-0.97) kgf/cm2, after which the extract is also drained, the resulting extracts are combined and concentrated in a vacuum, and the thick extract is dried to a dry state.
EFFECT: The invention enables to optimize the conditions of water-ethanol extraction and drying, reduce the consumption of reagents and the duration of the process, increase the yield of the target product and its quality, as well as to reduce the costs of subsequent purification, concentration and drying of the resulting product.
