Rumen - passing guanidine acetic acid - granulation and dry coating system

Jiangsu bohong is a professional enterprise engaged in the research, development, production and sales of pellet, pellet, pellet coating, drying and material airtight conveying equipment for livestock, poultry, aquatic products and ruminants premix and additives.Bohong company has strong technical force, with senior engineers, engineers and other engineering and technical personnel more than a dozen;The company is equipped with advanced, complete processing equipment and advanced processing technology.

Preparation method of coated guanidine acetic acid. Using guanidine acetic acid and coating material as raw materials, coating material is sprayed on the surface of granule guanidine acetic acid through fluidized bed bottom spray coating machine. The preparation steps are as follows :(1) pre-treatment;(2) Preparation of pellet core;(3) primary coating;(4) secondary coating;Jiangsu bo hong to package by guanidine acetic acid process is optimized, including the selection of materials and preparation of all parameters in the process of selection, preparation of good stability, high bioavailability package is guanidine acetic acid, especially for ruminants, reduces the product exists in the rumen degradation rate, and achieved the effect of slow release after by rumen, higher bioavailability.

Guanidine acetic acid belongs to amino acid and its derivatives. It is a kind of functional feed additive, which is suitable for the livestock and poultry mainly based on plant diet.The use of guanidine acetic acid plays an important role in improving performance, meat quality, energy metabolism and protein feed resource value of livestock and poultry.Most guanidine acetic acid obtained by the current preparation method is in the form of powder crystal, which has poor fluidity in practical use, especially in the use of ruminants. The degradation rate of the product is high in the rumen, and the effect of slow release can not be achieved after passing through the rumen, and the bioavailability is low.

In the preparation method of coated guanidine acetic acid, the guanidine acetic acid is protected by technical treatment to avoid fermentation and degradation in the rumen and directly into the small intestine before digestion and absorption, so as to achieve the purpose of improving the utilization rate of guanidine acetic acid.

The preparation method of coated guanidine acetic acid is as follows:

(1) Pretreatment

First, guanidine acetic acid was crushed and screened to obtain guanidine acetic acid powder.

(2) Preparation of shot core (extrusion shot blasting machine)

The guanidine acetic acid powder and the gelatinized starch solution were mixed evenly in the hydroxypropyl methyl cellulose solution, and then the spherical particles were made, and then the spherical particles were screened and put into the dryer for drying to obtain the pellet core.

(3) Primary coating (bottom spray coating/fluidized bed coating)

The pellet core is put into the pellet coating machine, and the bottom spraying method is used to precoat the pellet core with ethyl cellulose alcohol solution or polyacrylic resin Ⅳ alcohol solution as the packing material. The precoated pellet core is obtained and the precoated pellet core is screened.

(4) Secondary coating (bottom spray coating/fluidized bed coating)

The screened primary coated pellet core particles were placed in a fluidized bed coating machine. Through the bottom spray system of the fluidized bed coating machine, food-grade hydrogenated vegetable oil was melted and used as the coating material for secondary coating of the primary coated pellet core to obtain coated guanidine acetic acid.
