Embodiment Construction

[0004] Take surimi processing factory leftovers as an example: take 1,000 kg of surimi processing factory leftovers for treatment, and treat fish head (gills removed), scales, skin, bones, fins, and tails as one category, and viscera as another. One type, after washing, crushing, rewashing and filtering, directly hydrolyze with neutral protease (PH6.5-7.5 molecular weight 30000-40000) at normal temperature and pressure without heating. In the fish oil solution, also under normal temperature and pressure, add modified graphite to absorb fish oil respectively in these two types of solutions, and then separate it by pressing to produce 25 kg of crude fish oil. The solution after degreasing is concentrated by multi-effect evaporation, and spray-dried to make 86 kg and 80 kg of edible (medical) and feed hydrolyzed protein powder respectively. The residue separated by filtration is combined with other organic matter to make 80 kg of organic biological fertilizer through crushing, hi...

Abstract

The present invention relates to the industrial processing of aqueous product, especially the comprehensive utilization of fish leftover. The fish leftover including fish internal organs, filtered solid matter, etc. are sorted, washed, minced, enzymolyzed and filtered to eliminate residue; fish oil in the filtrate is absorbed with modified graphite; the other part of the enzymolyzed protein solution is used as feed and food material; the filter residue is used for producing organic fertilizer; and all these constitute one comprehensive technological process.

Description

Technical field: [0001] The invention relates to the industrial processing of aquatic product fish, especially the treatment and comprehensive utilization of leftovers from fish deep processing plants. Background technique: [0002] During the processing of fresh fish as raw material, leftovers will inevitably be produced. In the initial stage of freezing fresh fish, the raw fish is subjected to primary form processing, gills are removed, viscera is removed, head and fins are removed, or two longitudinal pieces of fish meat are taken, and the rest are discarded. In the processing of salted and dried fish products, these solid wastes also exist, and the washing and other process waste liquids in the process have not been counted. In the meat harvesting process in the processing of surimi products, in order to avoid too much fish oil mixed into the surimi, the mechanical meat harvesting rate is usually controlled at about 35%, and the raw materials accounting for about 65% of...
