Problems solved by technology

[0004] Ordinary sodium butyrate is highly irritating to the esophagus and stomach, and is easy to absorb moisture, which affects the processing quality of the feed, and has a strange smell, which affects the customer's recognition of the quality of the feed
In addition, ordinary sodium butyrate is mostly absorbed in the crop or stomach, and only a small part reaches the intestinal tract. At the same time, the gastric acid environment also has a greater impact on sodium butyrate, so ordinary sodium butyrate cannot satisfy the needs of various intestinal components. Nutrient requirements for sodium butyrate
In the process of feed processing, factors such as moisture content in feed, carrier type, pelleting temperature and other factors also have a great influence on the stability of ordinary sodium

Embodiment 1

[0014] Weigh 300g of sodium butyrate and dissolve it in water, then mix 100g of hydroxypropyl methylcellulose, 150g of chitosan and 100g of silicon dioxide and boil and expand in a fluidized bed at a high temperature of 230°C, then spray the sodium butyrate aqueous solution On the mixture of the above three substances, the sodium butyrate is embedded in the framework material and dried at a high temperature of 120-140℃; after the high temperature drying, it is cured at a low temperature of -5℃ to solidify the sodium butyrate particles, and then 200g carnauba palm Wax, 100g palm oil and 50g polyethylene glycol are dissolved in an organic solvent, and the bottom spray is carried out in a fluidized bed coating machine to evenly spray the coating material on the surface of sodium butyrate particles at a flow rate of 0.1-3L / min. The wind temperature is 50-90℃, the time is 3-4h, and the final product particle size is over 85% and passed through a 20-mesh analytical sieve. Finally, a ...

Embodiment 2

[0016] Weigh 700g of sodium butyrate and dissolve it in water, then mix 20g of hydroxypropyl methylcellulose, 50g of chitosan and 40g of silica and boil and expand in a fluidized bed at a high temperature of 230°C, and then spray the sodium butyrate aqueous solution On the mixture of the above three substances, the sodium butyrate is embedded in the framework material and dried at a high temperature of 120-140℃; after the high temperature drying, it is cured at a low temperature of -5℃ to solidify the sodium butyrate particles, and then 80g carnauba Wax, 50g palm oil and 10g polyethylene glycol are dissolved in an organic solvent, and the bottom spray is carried out in a fluidized bed coating machine. The coating material is evenly sprayed on the surface of sodium butyrate particles at a flow rate of 0.1-3L / min. The wind temperature is 50-90℃, the time is 3-4h, and the final product particle size is over 85% and passed through a 20-mesh analytical sieve. Finally, a sample of mi...

Abstract

The invention relates to a preparation method of an animal feed additive microencapsulation diolame sodium butyrate. The method comprises the following steps of: mixing hydroxypropyl methyl cellulose, chitosan and silica, boiling at high temperature of 230DEG C in a fluidized bed; spraying sodium butyrate aqueous solution on a mixture of three materials; drying at a high temperature, solidifying at a low temperature, solidifying and molding sodium butyrate particles; dissolving a coated material Brazil palm wax, palm oil and polyethylene glycol into an organic solvent, carrying out bottom-spraying and coating in a fluidized bed to obtain the evenly-coated sodium butyrate particles of which the mass percent of the sodium butyrate is 30-70%. The microencapsulation process is carried out on feed grade sodium butyrate power to avoid the loss of sodium butyrate in poultry crop and pig stomach, so as to reach the rear section of small intestine and cover the whole intestinal tract, meanwhile, overcomes foul smell, prevents air slaking, and protects sodium butyrate from losing in the process of feed processing.

Description

Technical field [0001] The patent of the present invention relates to a preparation method of microencapsulated coated sodium butyrate for animal feed additives. Background technique [0002] Sodium butyrate, also known as sodium n-butyrate, is converted into butyric acid after being eaten by animals. It is the same short-chain fatty acid (SCFA) as acetic acid and propionic acid. Butyric acid plays a major role in short-chain fatty acids. Unlike short-chain volatile fatty acids such as acetic acid or propionic acid, butyric acid is hydrolipidic and more lipophilic. It is relatively stable at pH 4-6 and is not easily decomposed. The molecular formula of sodium butyrate is C 4 H 7 O 2 Na, with a relative molecular mass of 110.09, is white to off-white, is a hygroscopic powder, like a fluff, has a special cheese-like smell, is easily soluble in water, and the pH value of the aqueous solution is alkaline. [0003] Sodium butyrate used as a feed additive in breeding can promote the gro...
