METHOD FOR PRESERVING OF SIBERIAN DEER VELVET ANTLERS

摘要

FIELD: agriculture, in particular, reprocessing, preservation and storage of natural raw material, in particular, Siberian deer velvet antlers.;SUBSTANCE: method involves cyclic thermal processing of antlers in vacuum drier followed by cooling, with drying process being provided in two steps including first step carried out at temperature of 65°C in chamber and vacuum value of 0.094-0.096 MPa for 4 hours, followed by cooling upon expiration of indicated time at temperature of 15-20°C for 12-24 hours, with cycle of operations being repeated until removal of 35-40% of moisture, and second step, wherein temperature in chamber is reduced to 45°C and drying process is continued at the same vacuum parameters for 7 hours, with following carrying out of cooling process under conditions similar to those of the first step, and processing of raw material with the same parameters until normal moisture content is 12-19%. Method allows drying process to be reduced to 6-9 days depending on antler size and weight parameters.;EFFECT: reduced loss of biologically active substances during reprocessing and preservation of antlers, reduced time for drying of basic material and reduced labor intensity.;2 cl, 3 tbl, 2 ex
