Problems solved by technology

[0010] In the process of the eucommia extract powder obtained by the above-mentioned method, the enzymolysis solution is directly alcohol-precipitated, then dextrin-included, and dried; resulting in a relative decrease in the yield of the product; The concentration is low, which increases the consumption of alcohol, and also increases the amount of subsequent wastewater treatment. The production cost is relatively high, and this technical problem has not been effectively solved.

Abstract

The invention belongs to the technical field of processing of cortex eucommiae, and particularly relates to a production process of cortex eucommiae fine powder. The production process is characterized by comprising the following steps: by adopting enzymatic hydrolysate filtrate obtained by degrading folium eucommiae or cortex eucommiae by adopting a biological enzyme method as a raw material, centrifugally separating, precipitating, concentrating, alcohol precipitating, separating, purifying, embedding by virtue of cyclodextrin, and drying, thus obtaining the cortex eucommiae fine powder. Theimprovement of the production process lies in twice centrifugal treatment, filtering and concentration prior to the alcohol precipitation, so that the concentration efficiency can be favorably improved, the production cost can be decreased, the quality of a product can be effectively protected, the heat exchanging efficiency is basically kept unchanged, the evaporation concentration efficiency can be improved, and the energy consumption can be effectively reduced.
