Technical Field
[0001] This utility model relates to the field of grinding device technology, specifically a pepper grinding device. Background Technology
[0002] A Sichuan pepper grinding device is a specialized piece of equipment for grinding and processing Sichuan peppercorns. Its main function is to physically grind dried Sichuan peppercorns into a fine powder or granules for use in food processing, seasoning, and medicine. Sichuan peppercorn powder is widely used in cooking, pharmaceuticals, cosmetics, spices, and some traditional medicines. Especially in Chinese cuisine, Sichuan peppercorn powder is an important seasoning in many dishes. However, an existing Sichuan peppercorn grinding device (publication number: CN221847294U) has the following drawbacks in use:
[0003] The traditional method directly feeds Sichuan peppercorns into a moving plate for stirring and heating. However, Sichuan peppercorns may contain impurities such as small stones and insects during storage. If not filtered, these impurities will enter the grinding system, affecting the grinding quality. Furthermore, Sichuan peppercorns tend to adhere to the grinding seat during grinding, and the residue on the surface of the grinding seat reduces the effective contact area for each grinding cycle, preventing the peppercorns from being fully ground. Therefore, this patent proposes a Sichuan peppercorn grinding device to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a pepper grinding device to solve the problems mentioned in the background art.
