Embodiment 1

[0032] Preparation of granule enzyme for temperature-tolerant aquatic feed:

[0033] Mix 10 kg of xylanase, 20 kg of calcium carbonate, 10 kg of ethyl cellulose, 40 kg of corn starch, and 20 kg of water to prepare a paste. The paste is granulated with a rocking granulator to obtain core particles; the granulator used It is a YK-160 swing pellet machine, with a rotating drum diameter of 160 mm, a rotating drum speed of 65 rpm, and a rotating drum swing angle of 365°±10°. The core particles obtained in the granulation step are shot blasted by a shot blasting machine, and finally the particle size of the core particles is controlled at 30-60 mesh. The shot blasting uses the QZL700 shot blasting machine, and the diameter of the shot blasting pot is 700 mm. The shot blasting speed is 100-200 revolutions (adjusted according to production requirements).

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 enzyme for temperature-resistant feed. Background technique [0002] A large number of experiments have proved that adding proper amount of bio-enzyme preparations such as phytase, β-glucanase and xylanase to animal feed can significantly improve the utilization rate of animal feed. With the limited improvement of feed production technology and the continuous strengthening of intensive farming, the proportion of pelletized feed is increasing. Feed pelletization can not only kill the microorganisms in the feed and improve the palatability of the feed, but also reduce dust and facilitate packaging, storage and transportation. But feed pelleting is a process of high temperature and humidity. In the process of granulation, the enzyme has to withstand both dry heat treatment and damp heat treatment. In the case of dry heat, the ...
