Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical raw material processing, in particular to drying equipment for pharmaceutical raw materials. Background Art

[0002] Drugs are substances used to prevent, treat and diagnose diseases. In theory, any chemical substance that can affect the physiological functions of the body's organs and the metabolic activities of cells falls into the category of drugs. In the process of drug production, in order to ensure the purity of the raw materials and prevent the contamination of foreign matter after drug production, the drugs are generally cleaned before production and then dried using drying equipment.

[0003] When using drying equipment to dry pharmaceutical raw materials, a heating device is used to evaporate the moisture contained in the pharmaceutical raw materials. However, when the moisture turns into water vapor and escapes, the water vapor easily adheres to the inner wall of the drying box and accumulates into condensation beads, which drip onto the pharmaceutical raw materials, thereby affecting the drying effect of the equipment.
