AI Technical Summary
Existing Rehmannia glutinosa drying equipment has the problem that when hot air flows from bottom to top, it can only contact the upper surface of one side of the Rehmannia glutinosa, resulting in slow drying speed of the lower layer and inconvenience of operation, especially for people of shorter stature, which reduces the efficiency of placement.
A device comprising a drying chamber, a rotating assembly, and a disc structure was designed. The rotation of the disc drives the screen cylinder to flip, achieving uniform drying of Rehmannia glutinosa. The disc is rotated by a motor driving a synchronous pulley and gear meshing, and heat is provided by heating strips to improve drying efficiency.
This method achieves uniform drying of Rehmannia glutinosa, shortens drying time, improves operational convenience, and is especially suitable for shorter individuals, thus enhancing processing efficiency.
