Description

Technical Field

[0001] The utility model relates to the technical field of pepper processing, and more specifically to a pepper primary screening device. Background Art

[0002] Sichuan pepper is a deciduous small tree of the Rutaceae family and the genus Zanthoxylum. After the Sichuan pepper matures, it needs to be dried and screened. Screening is to separate and screen the branches, leaves and seeds of the Sichuan pepper, which requires the use of a Sichuan pepper screening device.

[0003] For example, a Sichuan pepper screening device with announcement number CN214440940U includes a screening device body, the screening device body including a first housing, a first cavity defined within the first housing, a screening plate movably mounted within the first cavity, a fixing bar and a handle mounted on the top of the screening plate, and a vibration motor mounted on the bottom of the screening plate. The Sichuan pepper screening device installs an air blower within a second cavity to blow air away the dust and Sichuan pepper in the second cavity. The amount of air blown is insufficient to move the Sichuan pepper, and can only blow the dust to an ash chute, where it is discharged to the ground. At the same time, the Sichuan pepper, under the action of gravity, passes through the discharge port and reaches a storage box.

[0004] The Sichuan pepper screening device proposed in the above patent document lacks a structure for pre-treating the Sichuan pepper when actually used. Since some branches, leaves and skins of the Sichuan pepper need to be processed before the primary selection, the Sichuan pepper needs to be shelled and debranched. In addition, when screening the Sichuan pepper, some wet Sichuan pepper will be adsorbed on the surface of the screen and difficult to remove, so the Sichuan pepper needs to be dried and dehumidified.
