Background technique

Zanthoxylum bungeanum can not only be seasoned, preserved, dehumidified, but also used as medicine. Therefore, Zanthoxylum bungeanum has been favored by people since ancient times. Traditional Chinese pepper processing uses natural drying. This method has a long processing cycle and relatively low efficiency, and if it encounters rainy days, it is easy to cause mildew and other damage to the pepper. Later, people gradually adopted the method of mechanical drying. Compared with the traditional processing method, it has significantly improved the work efficiency, but there are still a series of problems such as uneven heating, high energy loss, inability to accurately control temperature, and secondary processing of pepper stems. question. For example, the Chinese patent ZL.03241937.6 uses a turntable drying rack to achieve the purpose of drying peppercorns, but the temperature change cannot be grasped during the drying process to achieve precise temperature control, thereby affecting the quality of the finished peppercorns; Chinese patent ZL.97239797.3 uses hot air pipes for heating, It can effectively adjust the air intake and exhaust volume and temperature, but the energy cannot be recycled. Therefore, pepper farmers are in urgent need of a dryer that can be processed on a large scale and has low energy loss and does not affect the quality of pepper after drying.
