Description

Technical Field

[0001] The utility model relates to the field of shrimp shell crushing devices, and more specifically to a shrimp shell crushing device used for chitosan extraction. Background Art

[0002] In the process of food processing and seafood processing, a large amount of shrimp shells, crab shells and other wastes are usually generated. These waste crustacean shells can be extracted and processed to obtain chitosan. Chitosan is widely used in the fields of medicine, food industry, cosmetics industry, etc. When extracting chitosan from shrimp shells, it is usually necessary to crush the shrimp shells. The main purpose of crushing the shrimp shells is to increase their surface area, which is beneficial to the subsequent extraction process and improves the extraction efficiency.

[0003] During the chitosan extraction process, shrimp shells need to be crushed. Existing shrimp shell crushing devices may have problems with insufficient stability during long-term operation and may be affected by vibrations, which may lead to poor crushing effects. After the shrimp shells are crushed, they need to be transported to subsequent processes for processing. However, the feed openings of some crushing devices are improperly designed, which limits the width of the conveying device and may cause uneven or wasted material after crushing, increasing the difficulty of material collection and affecting subsequent processing.
