Description

Technical Field

[0001] This utility model belongs to the field of Sichuan pepper processing technology, specifically relating to a device for removing impurities from Sichuan pepper. Background Technology

[0002] Sichuan peppercorns are an important seasoning widely used in food processing and cooking. After harvesting, Sichuan peppercorns often contain impurities such as leaves, stems, empty shells, and stones. These impurities not only affect the quality of the peppercorns but may also affect subsequent processing and use, therefore, it is necessary to remove impurities from the peppercorns.

[0003] Patent application (publication number: CN220879493U) discloses a Sichuan pepper impurity removal device for Sichuan pepper oil production, including a main body, a movable door, an inverted filter hopper, and a feed inlet. The feed inlet is located at the top of the main body, and the inverted filter hopper is located in the center of the main body, with sieve holes evenly distributed on it. Sichuan pepper is filtered through the sieve holes in the inverted filter hopper, while larger diameter impurities and broken leaves are intercepted and slide down the inclined surface of the inverted filter hopper to both sides of the main body. By opening the movable door, the locking block separates from the locking groove, allowing the impurities to be cleaned and discharged. The operation is convenient and quick.

[0004] In the aforementioned application, sieving and filtering are performed through the sieve holes on the inverted filter bucket. However, due to the steep incline of the inverted filter bucket, the peppercorns slide down the inverted filter bucket too quickly and have too short a contact time with the inverted filter bucket. Therefore, simply setting up an inverted filter bucket is insufficient to remove impurities from the peppercorns. Furthermore, in the aforementioned application, impurities and broken leaves slide to both sides of the main body of the impurity removal device, requiring manual opening of the door and manual cleaning, which affects efficiency.
