Description

Technical Field

[0001] The utility model relates to the field of chitosan preparation, and more specifically to a ball milling device for preparing functional chitosan. Background Art

[0002] Chitosan, a product of the natural polysaccharide chitin with some acetyl groups removed, has a variety of functions, including antibacterial, anti-cancer, lipid-lowering, and immune-enhancing properties. Chitosan is typically produced from shrimp and crab shells. To better process the shells, they must be processed for subsequent processing. Existing chitosan production processes typically require crushing the shells, but existing crushing equipment often lacks sufficient crushing efficiency, often resulting in limited results due to limitations in these equipment.

[0003] A mechanical ball mill is a device that can effectively grind materials into powder. However, its application in the field of chitosan production is still limited. There is a lack of mechanical ball mills for shrimp and crab shells. Ball milling of shrimp and crab shells can break the shells from larger blocks into fine particles or powders, significantly reducing the size of the shells and providing more uniform raw materials for subsequent processing.

[0004] Existing ball mills present inconveniences during feeding and unloading, and some even require disassembly of components for operation, which not only increases operational difficulty but also prolongs work time. Some ball mills lack filtration systems or have ineffective filtration systems, making it impossible to promptly separate qualified and unqualified materials after crushing. This requires additional time and steps to process substandard materials, reducing overall production efficiency. Utility Model Content
