Description

Technical Field

[0001] The utility model relates to the technical field of drying technology for removing liquid from solid materials or products, and specifically relates to a drying device for raw material drug processing. Background Art

[0002] A raw material drug refers to any substance or mixture of substances used in drug manufacturing. When used in pharmaceutical production, it becomes an active ingredient of a drug. It is prepared by chemical synthesis, plant extraction, or biotechnology, but it is a substance that patients cannot take directly. Generally, it needs to go through subsequent treatments such as adding excipients to become the final drug product.

[0003] In order to facilitate the subsequent processing of raw material drugs, a drying device is usually used for drying treatment. The drying device is divided into various forms such as vertical and horizontal. Among them, the bottom space of the horizontal drying device is larger, which makes the raw material drugs more dispersed, thereby increasing the contact area between the raw material drugs and hot air, and improving the drying efficiency of the raw material drugs. However, due to the larger bottom space of the horizontal drying device, the discharge port is relatively small, which makes the discharging process more troublesome, takes a longer time for discharging the horizontal drying device, and reduces the use efficiency of the horizontal drying device.
