METHOD FOR OBTAINING DRY EXTRACT OF BAICAL SKULLCAP FOR FARM ANIMALS AND POULTRY (OPTIONS)

摘要

FIELD: feed industry.;SUBSTANCE: inventions group relates to the fodder industry, namely to methods for producing a dry extract of Baical skullcap for a feed additive for farm animals and poultry. The method is hacked by the fact that the raw material is crushed and moistened in a water-ethanol solution, then transferred to an extractor, poured with a water-ethanol solution, heated and at the first stage, extraction is carried out under vacuum, after which the extract is drained, and the mass is re-poured with a water-ethanol solution, heated and extracted under vacuum, after which the extract is drained. The resulting mass at the third stage is poured with distilled water and extraction is carried out under pressure, after which the extract is also drained. The resulting extracts are combined and concentrated in vacuum, and the thick extract is dried to dryness.;EFFECT: invention provides the possibility to optimize the modes of water-ethanol extraction and drying, reduces the consumption of reagents and the duration of the process, increases the yield of the target product and its quality, and also reduces the costs of subsequent purification, concentration and drying of the resulting product.;10 cl, 2 ex
