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 utilization, and more specifically, relates to a crustacean solid waste recycling system and method. Background technique [0002] With the rapid growth of the consumption of shrimp and crab aquatic products in recent years, solid crustaceans such as shrimp shells and crab shells have accumulated like mountains. According to incomplete statistics, the amount of solid crustacean waste generated by the consumption of aquatic products in my country exceeds 8.5×10 each year. 5 Ton. These wastes are usually thrown away directly as domestic garbage. Huge natural resources are not only wasted, but also cause serious pollution to the ecological environment. It is reported that only a very small part of the crustacean has been recycled. For example, shrimp shells and crab shells are initially processed into shrimp and crab shell powder to be used as additives for maricultur...
