Problems solved by technology

However, under the increasingly serious pollution of seawater in recent years, golden pomfret farming is often under the stress of water quality deterioration, bacterial proliferation, bad weather (typhoon) and other environments. The economic loss of households is serious, and the existing golden pomfret feed is affected by various factors (pH, temperature, osmotic pressure, water flow impact, chemical reaction, etc.) after entering the water, and various reactions, such as dissolution and swelling , breaking, powdering, peeling, etc., poor stability, easy to dissolve and lose nutrients, make water eutrophication, and reduce the effective intake of gold pomfret feed, which not only pollutes the water environment but also wastes feed, and Due to the unique characteristics of golden pomfret's living habits and physiological mechanism, there are high requirements on the crushing particle size, mixing uniformity, feed formability and water resistance of golden pomfret feed, while the existing golden pompano It is difficult for the feed to meet these requirements and the cost is high

preparation example Construction

[0017] The steps of the preparation method are: feeding→primary cleaning→primary mixing→iron removal→crushing→secondary mixing→conditioning→expanding→drying→grease spraying→cooling→packing;

[0018] In the production process, the steam pressure of the curing machine is at 7kg / cm 2 ~10kg / cm 2 The expansion coefficient of the product is between 1.7 and 2.0; the moisture content of the material after conditioning is 28% to 35%, and the temperature of the material is 100°C-120°C.

[0019] During the secondary mixing, the oil is added at the same time, and the steam water is added at the same time as the tempering, and the remaining steps adopt the existing conventional technology.

[0020] The prepared production line process is as follows: the feed ingredients are dried by the dryer, dusted by the pulse dust collector, passed through the feeding grid screen, entered into the feeding hopper, entered into the primary cleaning screen through the elevator, passed through the permane...

Abstract

The invention relates to a golden pompano immune promoting compound feed and a preparation method thereof. The feed comprises fish meal, flour, shrimp pulp, bean meal, corn protein powder, fish oil, meat meal, a plurality of vitamins, a plurality of mineral substances, immunopotentiator, bilineurine and dibastic sodium phosphate; and the preparation method comprises the following steps: batching, primary cleaning, primary mixing, iron removing, crushing, secondary mixing, conditioning, puffing, drying, grease spraying, cooling and packaging. The formula of the feed is scientific and reasonable, and the high-efficiency pollution-free immunopotentiator is added into the feed, which causes the feed to have high-quality crushing particle size, mixing uniformity, feed formability, water resistance, etc.; furthermore, the compound feed has the advantages of improving the absorption and utilization rates, satisfying the nutrition requirements of the golden pompano, improving disease resistance of the fish, and promoting the quick and sound growth of the fish; thus greatly shortening the breeding cycle, reducing the breeding cost and reducing the pollution to water body; and the preparation method is scientific and reasonable and has obvious economic benefit and environmental benefit.

Description

technical field [0001] The invention belongs to the technical field of fish feed, and more specifically relates to a golden pomfret immune growth-promoting compound feed and a preparation method thereof. Background technique [0002] The scientific name of golden pomfret is oval pomfret, and the local name is yellow waxed pomfret and golden pomfret. Hainan, Guangdong, Fujian and other places carry out large-scale breeding, and the annual seedling production is more than 200 million. However, under the increasingly serious pollution of seawater in recent years, golden pomfret farming is often under the stress of water quality deterioration, bacterial proliferation, bad weather (typhoon) and other environments. The economic loss of households is serious, and the existing golden pomfret feed is affected by various factors (pH, temperature, osmotic pressure, water flow impact, chemical reaction, etc.) after entering the water, and various reactions, such as dissolution and swel...
