Process for producing shellfish premix feed

Abstract

The invention discloses a process for producing a shellfish premix feed, which is characterized in that the shellfish premix feed is prepared by using attapulgite, flours, corn husks and the like as carrier raw materials through the steps of adding bioactive peptides into the carrier raw materials by a liquid adding device through using a high-pressure atomized spraying method; drying the obtained evenly-mixed materials by air flows, then carrying out ultra-micro pulverization on the materials, and adding fish oil into the materials in the process of pulverization; then adding feed decavitamin and composite trace elements into the materials, after evenly mixing the materials, adding bioactive peptides and immune polysaccharides into the mixed materials; drying the mixed materials by air flows until the moisture content of the mixed materials is 10 to 15 percent, sieving the obtained materials so as to ensure the materials can completely pass through a 90-mesh sieve to obtain the finished product of the premix feed. The process for producing the shellfish premix feed has the advantages that the process is more reasonable, and the premix feed is ensured to be environmental friendly and safe; the losses of vitamins, microelements and other active materials can be reduced; and oil-phase, solid-phase and aqueous-phase materials in the product are added simultaneously, after the materials are mixed and dried, an envelope can be formed on the surface of the product, thereby improving the product stability.

Description

technical field [0001] The invention relates to a production method of an animal feed additive, in particular to a production process of a crustacean feed premix. Background technique [0002] The scale and output of my country's aquaculture industry ranks first in the world. However, the hidden dangers of quality and safety in the development of the aquaculture industry are extremely serious. In 2004 alone, my country's aquatic products were detained by foreign countries for 308 times due to safety problems. Drug residues are the main source of aquatic product safety problems, and are closely related to the core formula premix of feed products and their processing technology. However, whether it is the formula design of the premix or the processing technology of the product, the technological content is generally not high. The research on the formula of premix at home and abroad, especially the research on the formula of special aquatic animals is not deep enough, and the...

Problems solved by technology

However, due to the different growth environments and nutritional requirements of aquatic animals and livestock and poultry animals, the water-soluble nutrients in the premix product are easily lost in the water environment, and the practice of adding drugs to the livestock and poultry premix for disease prevention and treatment , extremely unsuitable for aquafeed production

At present, there is still a lack of targeted green aquatic premix products in the domestic and foreign markets. At the same time, there are many problems in the processing of premix products. The problem of serious loss in the process of material solid powder processing has brought many tests for high-quality premix products
