METHOD OF PROCESSING FIR TREE GREENERY EXTRACTION WASTES

摘要

FIELD: agriculture.;SUBSTANCE: proposed method envisages fir tree greenery extraction wastes being treated with a water-immiscible organic solvent and further extraction. The extraction process is as follows. First water is added to the wastes mass that is subsequently maintained at a temperature of 80-90C during three hours, the heating combined with solvent residues stripping off the stratum of greenery mass with water steam. The resultant aqueous extract undergoes concentration under vacuum conditions at a temperature of 60-80C. The final product (concentrated extract that may be in the form of either a water solution containing 50-70% of solids or a solid matter) is utilised as a fodder additive.;EFFECT: environmentally friendly method of processing fir tree greenery extraction wastes enabling production of a bioactive preparation to be utilised in the sphere of agriculture.;2 tbl, 7 ex
