Prawn floating feed as well as preparation process and preparation device thereof

Abstract

The invention discloses a prawn floating feed formula. The feed comprises the following components in parts by weight: 10-15 parts of a multi-vitamin premix, 20-30 parts of a mineral element premix, 8-12 parts of taurine, 30-50 parts of carrier wheat flour, 20-25 parts of an adhesive, 5-10 parts of antibiotics, 10-13 parts of Sanhuang, 8-12 parts of andrographis paniculata, 20-28 parts of beet, 15-20 parts of sugarcane powder, 2-6 parts of saccharomycetes, and 10-13 parts of soya lecithin. Meanwhile, after the raw materials are mixed and puffed through a material mixing structure, the feed is flattened through a driving extrusion roller and a driven extrusion roller, integrated production is achieved, repeated manual carrying is avoided, meanwhile, in the flattening process, sectional type tabletting is achieved through grooves and protruding blocks, subsequent feed containing is facilitated, and the feed mixing speed is accelerated. Meanwhile, the nutrition degree of some fresh solid raw materials is kept through the arrangement of the crushing rollers, so that workers can directly process the fresh solid raw materials, and the use of the workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a floating feed for prawns, a preparation process and a preparation device thereof. Background technique [0002] Prawns are divided into Penaeus vannamei and Penaeus China. Penaeus vannamei does not have a very strict requirement for animal bait, as long as the ratio of protein in the bait ingredients accounts for more than 20%, it can grow normally. Native to the waters of the Pacific coast of South America, mainly distributed in the tropical waters of the western Pacific coast of the United States, from the Gulf of Mexico to the central part of Peru, and more concentrated in the waters near Ecuador, Chinese prawns, and sea-caught prawns. The yellowish prawns are male prawns, and the cyan prawns are female prawns. The sea-caught non-farmed Chinese prawns are generally 30 grams to 50 grams. The larger the size, the rarer it is; most of them are artificially cultured. [0003] Howe...

AI Technical Summary

Problems solved by technology

[0003] However, in the process of shrimp cultivation, whether it is South American shrimp or Chinese shrimp, most of the shrimp seedlings and adult shrimps will choose not to eat when the shrimp seedlings or adult shrimps appear sick during the cultivation period, which has resulted in the inability to use feed to treat shrimp. treatment, and the virus resistance of prawns cannot be improved through prawn feed in the existing feed;

[0004] And in the existing production of prawn floating feed, most of the floating feed is stored and released by flattening the floating feed, but in the existing preparation device, most of the feeding is turned manually, the mixing speed of the feed is relatively slow, and the turning of the machine is relatively slow. Most of the feeds are prepared and mixed together with some powder feeds that have been processed, which greatly reduces the nutritional level of some fresh solid feeds. Therefore, a floating feed for prawns and its preparation process and preparation device are proposed.
