Embodiment 1
[0013] (1) Weigh each raw material:
[0014] Glyceryl monostearate 100g
[0015] Sucrose monolaurate 150g
[0016] Sorbitan monolaurate 100g
[0017] Glycerol monolaurate 100g
[0018] Polyethylene glycol 250g
[0019] Silica 300g
[0020] (2) The preparation method is: the first step is to heat and melt sucrose monolaurate and sorbitan monolaurate at 100-180°C, then keep it at 60-80°C; in the second step, add silica to adsorb into fine particles Granules; the third step is to dissolve glycerol monostearate, glycerol monolaurate and polyethylene glycol with an organic solvent, and spray the above solution evenly on the fine particles using a bottom jet fluidized bed at a flow rate of 0.1~3L / min , The air inlet temperature is 45~60℃, and the spraying time is 3~4h, which is the finished product. 95% of the finished product passed the 30-mesh analytical sieve.

Abstract
The invention relates to an animal feed additive, i.e. a composite grease emulsifying agent for a coated feed, and a preparation method thereof. The composite grease emulsifying agent for the coated feed comprises the following components in raw material ratio in percentage by weight: 10 percent to 30 percent of glyceryl monostearate, 10 percent to 30 percent of sucrose monolaurate, 5 percent to 20 percent of sorbitol anhydride monolaurate, 5 percent to 10 percent of glycerol monolaurate, 20 percent to 50 percent of polyethylene glycol and 20 percent to 50 percent of silicon dioxide. The preparation process of the grease emulsifying agent comprises the following steps of: firstly, carrying out heat preservation after heating and melting high HLB (Hydrophile-Lipophile Balance) value raw materials; adding silicon dioxide to adsorb to form fine particles; and then dissolving low HLB value raw materials and polyethylene glycol by an organic solvent, uniformly spraying the solution on the fine particles to obtain a finished product. Four food emulsifying agents with different HLB values, which are selected by the invention, are processed by scientific compatibility, are suitable for emulsifying various greases in the feed, have stable emulsifying effects and can keep the state of not breaking emulsion for a long time; after being subjected to coating processing, all of four emulsifying agent ingredients can tolerate high temperature treatment and are suitable for pelletizing processing of the feed.
Description
1. Technical field [0001] The invention relates to an animal feed additive, in particular to a film-coated feed compound oil emulsifier and a preparation process thereof. 2. Background technology [0002] With the rapid development of modern farming, the growth performance of livestock and poultry has been continuously improved in the breeding process, and its requirements for nutrients, especially energy, are also getting higher and higher. As a high-energy feed ingredient, fat is often used in livestock and poultry diets to increase dietary energy. However, due to the immature development of the digestive system and the insufficient secretion of endogenous bile salts and lipases, it is difficult for young animals to fully emulsify the fat in the feed, which greatly limits the digestion and absorption of oil, so it must be treated externally. Sources add substances that improve fat utilization. Adding emulsifiers to feed can improve the digestion and utilization of fat by...
