Place the Lycium chinensis on the material tray and then put the tray into the drying room. You should adjust the temperature on the control panel and keep the inlet air temperature between 55°C-60°C. The return air temperature should be controlled between 40°C-45°C, the inlet air humidity should be controlled between 35-45%, and the wind speed. Should be controlled about 0.20-0.35m/s. The drying time should be last for 33-35 hours, then the Lycium chinensis can be dried completely.
