Abstract

The invention belongs to the technical field of aquatic feed, and particularly relates to expanded feed for penaeus vannamei boone and an expanding method of the expanded feed. By replacing existing expensive fish meal with a fish meal substitute and newly adding a phagostimulant and a stabilizer in water, the produced feed can well meet the growth requirements of the penaeus vannamei boone, and the feed is good in stability in water, sufficient in ingestion and not prone to waste. In addition, the expanding method has the advantages of being good in expanding effect and thorough in expanding,an improved double-screw expanding machine has the two flexible and selectable modes of direct discharging before expanding or steam-assisted hardening and tempering, the selection action of the twomodes is simple and efficient, residual feed powder is easily accumulated in the overall structure of a feeding pipe, a steam-assisted hardening and tempering structure is simple and reliable, and thefeeding pipe on the expanding machine has the advantages of being high in overall structural stability and convenient to disassemble, assemble and maintain.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to an extruded feed for Penaeus vannamei and an extruding 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 feed refers to a feed that has undergone an extruded process. The extruded feed has the advantages of easy absorption, stable structure, hygiene and safety. This feed can just meet the breeding requirements of Penaeus vannamei. [0003] The existing feed for Penaeus vannamei mainly includes fish meal, soybean meal, fish oil and flour, but the price of fish meal is relatively expensive, which will greatly increase the cost of feed. Therefore, an extruded feed produced with fish meal substitutes is urgently needed in the market , and it is necessary to ensure that the vannamei shrimp is suitable ...
