High-economical-efficiency expanded sinking compound feed for penaeus vannamei boone and preparation method of expanded sinking compound feed

Abstract

The invention belongs to the technical field of aquatic feed, and particularly relates to a high-economical-efficiency expanded sinking compound feed for penaeus vannamei boone and a preparation method of the expanded sinking compound feed. By adding a plant extract enhancer, an animal extract enhancer and an enhancer sustained-release agent into the existing feed composition, the effect of obviously enhancing the disease resistance and immunity of the penaeus vannamei boone after the feed is applied is achieved. According to the preparation method, a straight cylinder type drying machine is adopted and structurally comprises a first heat preservation square cylinder, a drying square cylinder, a second heat preservation square cylinder, a height limiting material scraping plate, a scrapingfalling material collecting unit, an electric heating wire heater and a material returning plate unit, and has the beneficial effects that the heating drying structure is reasonable and effective, the heat utilization rate is high, the feed in all positions of the upper part and the lower part can be heated sufficiently, the discharging amount after drying is kept consistent, materials are not prone to leaking from a conveying belt after drying, falling materials before drying can be conveniently returned, dried and heated and all the feed can be output after being dried and heated.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to a high-economical extruded sinking compound feed for Penaeus vannamei and a preparation method thereof. Background technique [0002] Penaeus vannamei, belonging to the family Penaeidae, is a cultured shrimp species with high economic value, and its staple food is animal feed. On the other hand, extruded sinking compound feed refers to a multi-component compound feed that goes through the extruding process and sinks to the bottom of the water after being fed, and is eaten by benthic animals. Require. [0003] The existing feed for Penaeus vannamei mainly includes fish meal, soybean meal, fish oil, flour, vitamin additives, trace element additives and adhesives in its nutritional composition. There is an urgent need in the world for an improved special feed that can ensure the healthy and rapid growth of Penaeus vannamei, and the preparation method and equipment...

AI Technical Summary

Problems solved by technology

[0005] However, the Penaeus vannamei feed in this invention patent has the problem that the combination of additive components is not reasonable enough, which will eventually lead to the lack of self-immunity of Penaeus vannamei
