Crab shell enzymolysis device

Abstract

The invention discloses a crab shell enzymolysis device, which is characterized by comprising: an enzymolysis pool (1), a crab cage (2), a support bar (3), a slide cylinder (4), lifting bars (5), and a cleaning pool (6); the slide cylinder (4) is disposed on the support bar (3) and can slide on the support bar (3); the lifting bars (5) are disposed at two ends of the support bar (3); the crab cage (2) is hung below the slide cylinder (4); the enzymolysis pool (1) and the cleaning pool (6) which are parallelly arranged are disposed below the crab cage (2). The crab shell enzymolysis device provided by the invention removes mucous membranes and residual crab meat on crab shell surfaces in an enzymolysis mode. When the enzymolysis completes, the mucous membranes and residual crab meat are enzymolyzed and dissolved out effectively.

Description

technical field [0001] The invention relates to a crab shell enzymatic hydrolysis device, in particular to an enzymatic hydrolysis device for enzymolyzing the mucous membrane and residual meat on the surface of crab shells, belonging to the technical field of biological enzymatic hydrolysis equipment. Background technique [0002] my country is rich in crab resources, and the main processing of crabs is to collect large pieces of crab meat under the breast shell and in the claws to process canned crab meat, and some are processed into crab sauce, crab yellow sauce, crab oil and crab flavoring seasoning. and other products. While the crab is processed, a lot of leftovers are produced, including the small feet of the crab and a large amount of crab shells. Crab shell is the main raw material for the production of chitin. It is worth noting that crab legs and crab shells also contain a considerable portion of crab meat, and usually these residues must be removed before chitin ...

AI Technical Summary

Problems solved by technology

[0004] Although this method is simple and has strong applicability, it produces a large amount of wastewater and causes serious environmental pollution.

When the traditional process produces chitin, the process wastewater produced is characterized by four highs: high acid concentration, high alkali concentration, high inorganic salt (mainly calcium chloride, etc.) content and high organic matter (mainly soluble protein, pigment and fat etc.) content, resulting in serious pollution of chitin production process, while a lot of useful resources are wasted
