A system and method for recycling crustacean solid waste

Abstract

The invention belongs to the related technical field of crustacean solid waste recycling, and discloses a crustacean solid waste recycling system and method. The system comprises a carapace pretreatment subsystem, a chitosan extraction subsystem and a protein extraction subsystem, wherein the chitosan extraction subsystem and the protein extraction subsystem are connected to the carapace pretreatment subsystem separately; the carapace pretreatment subsystem is used for performing two-stage smashing and solid-liquid separation on crustacean solid waste raw materials, thereby pretreating the crustacean solid waste raw materials into a solid substance and a liquid substance in a flowing state, and the solid substance and the liquid substance enter the chitosan extraction subsystem and the protein extraction subsystem; the chitosan extraction subsystem is used for treating the solid substance to obtain a chitosan product; the protein extraction subsystem is used for treating the liquid substance to obtain a protein product. The crustacean solid waste recycling system and method have the advantages that the extraction efficiency is higher, the operation is simple, and the production cost is low.

Description

technical field [0001] The invention belongs to the related technical field of crustacean solid waste recycling, and more specifically relates to a crustacean solid waste recycling system and method. Background technique [0002] With the rapid growth of consumption of shrimp and crab aquatic products in recent years, crustacean solid wastes such as shrimp shells and crab shells have piled up like mountains. According to incomplete statistics, at present, various crustacean solid wastes produced by the consumption of aquatic products in my country exceed 8.5×10 5 Ton. These wastes are usually directly discarded as domestic garbage, and huge natural resources are not only wasted in vain, but also cause serious pollution to the ecological environment. It is reported that currently only a very small part of the carapace has been recycled, such as the preliminary processing of shrimp and crab shells into shrimp and crab shell powder, which can be used as an additive for maricu...

Problems solved by technology

[0005] Aiming at the above defects or improvement needs of the prior art, the present invention provides a crustacean solid waste recycling system and method, which is based on the recycling characteristics of the existing crustacean solid waste, aiming at the recycling of crustacean solid waste The key components of the system, such as the shell pretreatment subsystem, the chitosan extraction subsystem and the protein extraction subsystem structure and the link relationship between the components, have been studied and designed, so that the system can simultaneously extract from crustacean solid waste Chitosan and protein products are extracted, which solves the problems of cumbersome process, low efficiency, energy waste and environmental pollution in the current recycling process of crustacean waste. It has the advantages of simple operation, low production cost, strong adaptability and high processing efficiency. advantage
