Process for coating multi-vitamin for cow rumen

Abstract

The invention discloses a process for coating a multi-vitamin for a cow rumen. The process comprises the following specific steps of (1) weighing raw materials and mixing to obtain a first mixed raw material, adding carboxymethyl cellulose to the first mixed raw material for granulation to obtain a core material; and (2) adding a coating material to the core material and sampling the coating material through a peristaltic pump at a speed of 8-11 ml / min under the conditions that the atomization pressure is 1.2-1.8MPa, the air-induced frequency is 50HZ, the compressed air temperature is 52-60 DEG C, the air inlet temperature is 36-46 DEG C and the air outlet temperature is 22-25 DEG C to obtain a finished product. A compound polymer material sensitive to a pH value is a coating wall material, a bottom-spray fluidized bed coating process of coating after granulation is adopted and relatively ideal physical coating protection can be carried out on the multi-vitamin of a ruminant; and the ratio of the coating material and the core material is 6-8%, so that the rumen protection rate of a prepared multi-vitamin-coated product is greater than 70%, the release rate of a true stomach (abomasums) is greater than 60% and the economical benefit of a feeder can be improved.

Description

technical field [0001] The invention relates to the field of livestock and poultry vitamin production, in particular to a cow rumen protection compound vitamin coating process. Background technique [0002] Rumen protection technology is an important technology to improve the utilization rate of nutrients in ruminant diets. It is a special treatment of certain nutrients (such as protein, amino acid, fat, starch and vitamins, etc.) to protect them and reduce them. It is fermented and degraded in the rumen of ruminants, and then directly enters the abomasum and small intestine, and then is released for digestion and utilization. The use of rumen protection technology can reduce the degradation rate of nutrients in the rumen and increase the digestion and absorption of nutrients in the small intestine, thereby improving the utilization rate of digestion and absorption of nutrients in ruminants. For the rumen protection technology of ruminant vitamins, the coating process is ma...

Problems solved by technology

For the rumen protection technology of ruminant vitamins, the coating process is mainly used at present. The coating process that has been publicly reported mostly uses palm oil fat powder as the packaging material, and the process mostly uses stirring and mixing, and the coating quality and rumen protection effect are not ideal. , which reduces the economic benefit of the breeder
