example 1

[0008] Example 1, polyvinyl alcohol 10Kg, copovidone 25Kg, hypromellose 20Kg, talcum powder 30Kg, magnesium stearate 5Kg, Tween-80 is 5Kg, castor oil 5Kg, colorant: 1Kg, the above each combination Mix evenly at high speed to obtain a film coating agent. When in use, put an appropriate amount of film coating agent into a solvent to prepare a 6-18% suspension, and spray the suspension evenly on the surface of phytase granules through a peristaltic pump and a high-pressure spray gun, and work continuously for 3-5 days. Hours, the phytase granules become uniform color granules. That is, the coated phytase is obtained.

example 2

[0009] Example 2, polyvinyl alcohol 20Kg, copovidone 30Kg, hypromellose 30Kg, talcum powder 10Kg, magnesium stearate 8Kg, Tween-80 is 1Kg, castor oil 1Kg, colorant: 3Kg, combine the above Mix evenly at high speed to obtain a film coating agent. The method of use is the same as Example 1.

example 3

[0010] Example 3, polyvinyl alcohol 30Kg, copovidone 10Kg, hypromellose 10Kg, talcum powder 20Kg, magnesium stearate 15Kg, Tween-80 is 10Kg, castor oil 10Kg, colorant: 5Kg, the above each combination Mix evenly at high speed to obtain a film coating agent. The method of use is the same as Example 1.

Abstract

The invention relates to a method for preparing a film coating agent for coating phytase, in special coating multilayer outside phytase feed additive granules. The film coating agent is prepared from polyvinyl alcohol, co-povidone iodine, hydroxypropyl methylcellulose, talcum powder, magnesium stearate, tween-80 and ricinus oil which are evenly mixed at a high speed according to certain weight percentage. The method has the advantages that because of the presence of an isolated layer, the phytase feed additive granules can keep property of enzyme stable during usage, storage and sale, and have remarkably enhanced capability of resisting external adverse environments such as high temperature, high moisture and the like. After the surfaces of the granules are coated, the granules have better compactness, the activity content evenness of the enzyme is high, the animal feed is easy to be mixed evenly, and the animal is fed in balance; the granules have bright color, are round and beautiful, and have good flowing property; the granule specific gravity is similar to the feed specific gravity, and the granules are easy to be mixed evenly, and do not grade, generate static electricity, mutually adsorb and unite; and the coating material has good water solubility, can be quickly disintegrated and released in gastric juice, and has high bioavailability.

Description

One: technical field: [0001] The invention relates to a method for preparing a coating agent specially used for outer coating and separating layers of phytase feed additive particles. Two: background technology: [0002] Phytase is a new protease preparation and a green feed additive with excellent properties. The importance of phytase in the feed industry is becoming more and more prominent, but due to its photosensitivity, heat sensitivity and the influence of temperature and humidity, its properties are unstable. According to research, the most suitable acidic pH value of phytase activity is 5.5, and the optimum temperature is 45°C. Experiments have shown that the pH value and temperature have a certain impact on phytase. Add phytic acid to the feed Enzymes must consider the influence of these factors on enzymes. At present, most of the phytases produced in China are not coated. There are mainly two production methods: adsorption drying and spray drying. Adsorption dry...
