Abstract

The invention discloses an envelope production process for granzyme for a temperature-resistant feed. The process comprises the following steps of: mixing raw enzyme and a carrier, namely mixing the raw enzyme and the carrier to obtain paste, wherein the carrier consists of calcium carbonate, ethyl cellulose, corn starch and water, and the granzyme is prepared from the following raw materials in percentage by weight: 20 percent of calcium carbonate, 10 to 20 percent of ethyl cellulose, 20 to 30 percent of corn starch, 20 to 40 percent of raw enzyme and the balance of water; granulating; performing shot blasting; coating; and drying. By the process, the thermal stability, particularly the humidity resistance of the enzyme can be improved. Enteric polyacrylic resin latex is used as a coating material, so the use of an organic solvent can be avoided in the coating process, the production is safe, and three wastes are not generated.

Description

Technical field: [0001] The invention relates to the technical field of enzyme additives for feed, in particular to a coating production process of granular enzymes for temperature-resistant feed. Background technique [0002] A large number of experiments have proved that adding an appropriate amount of biological enzyme preparations such as phytase, β-glucanase and xylanase to animal feed can significantly improve the utilization rate of animal feed. With the improvement of feed production technology and the continuous strengthening of intensive farming, the proportion of pelleted feed is increasing. Feed granulation can not only kill microorganisms in the feed, improve the palatability of the feed, but also reduce dust and facilitate packaging, storage and transportation. But feed pelleting is a high temperature and high humidity process. In the process of granulation, the enzyme has to withstand both dry heat treatment and humid heat treatment. In the case of dry heat,...
