Description

The present invention relates to the field of pharmaceutical manufacturing, and specifically is a drying apparatus for the pharmaceutical and chemical industries.

Drying of medicines is necessary in the manufacture of medicines. Existing drug drying devices use a drying cylinder with a built-in stirring rod to dry the drug, but when the stirring rod rotates, the drug may be crushed and damaged. In addition, when the medicine rotates with the rotation of the drying cylinder, it may cause a decrease in the heat absorption rate in the furnace, waste of heat, and an extension of the drying time. Furthermore, simply by rotating the stirring rod or drying tube, the drying of the drug becomes non-uniform, which affects the properties of the drug. The present invention discloses a device capable of solving the above problems.
