Abstract

The invention aims to provide a production method of coated enzyme granules, which comprises the following steps: mixing, extruding, granulating, drying, coating and the like to produce the enzyme-containing granules. The method is simple in process, and can effectively save the production cost and lower the energy consumption due to the adoption of the lower processing temperature; and the prepared enzyme granules have the advantages of high temperature tolerance and small loss of enzyme activity.

Description

technical field [0001] The invention relates to the technical field of coating and granulation, in particular to a production method of coated enzyme granules. Background technique [0002] At present, enzyme preparations have been more and more widely used in feed, textile, chemical and other fields. Commonly used enzyme preparations are in the form of powder or liquid, but such products generally have problems such as serious reduction of enzyme activity and short shelf life during production and use, and the powder is harmful to the health of production personnel and the environment during the production process. All have a small impact. Therefore, research on enzyme granule preparations has become a hot spot in recent years. [0003] One of the methods commonly used to prepare enzyme granules is to use coating technology, that is, to coat one or several layers of coating layers with specific functions on the outside of the enzyme to isolate the enzyme from the external...
