Crab shell swing-type enzymolysis device

Abstract

The invention discloses a crab shell swing-type enzymolysis device, which is characterized by comprising: an enzymolysis pool (1), a crab cage (2), hoisting devices (3) and a cleaning pool (4); two hoisting devices (3) are provided and are symmetrically arranged at two sides of the enzymolysis pool (1) and the cleaning pool (4); the hoisting device (3) comprises a support bar (5), a slide cylinder (6), and lifting rods (7); the lifting rods (7) are located at two ends of the support bar (5); the slide cylinder (6) is located on the support bar (5) and can slide on the support bar (5); a hanging ring of the crab cage (2) at the same side as the slide cylinder (6) is hung below the slide cylinder (6); the enzymolysis pool (1) and the cleaning pool (4) which are parallelly arranged are disposed below the crab cage (2). The crab shell swing-type enzymolysis device provided by the invention enables the crab cage to be in a swing-type motion state driven by the hoisting device, and thus has good dissolution effect on residual crab meat and mucous membranes, and short dissolution time.

Description

technical field [0001] The invention relates to a swing-type enzymolysis device for crab shells, in particular to a swing-type enzymolysis device for enzymolyzing the mucous membrane and residual meat on the surface of crab shells, and belongs to the technical field of biological enzymolysis 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

[0005] In addition, the traditional method of removing the residual meat and mucous membranes on the crab shell is generally a static method, that is, the soaking method. The hydrolyzate and the hydrolysis device are both in a static state. The static state does not use the dissolution of the decomposed residual meat and mucous membranes, resulting in hydrolysis. Long time, low hydrolysis efficiency
