Xuzhou Kangtai Biological Products Co., Ltd. is a high-tech enterprise specializing in the extraction of pharmacologically active substances from ginkgo biloba leaves, such as ginkgo flavones and ginkgolides. The company operates two GBE production lines, with an annual output of 60 tons of ginkgo flavones and 300 kg of ginkgolides. It serves as the front-end extraction workshop for Yangtze River Pharmaceutical Group, a leading company in China's traditional Chinese medicine pharmaceutical industry, supplying over 30 tons of ginkgo biloba extract to Yangtze River annually. The products have been tested and certified by China Pharmaceutical University, Shanghai Institute of Traditional Chinese Medicine, and Nanjing Institute of Botany, Chinese Academy of Sciences, with all indicators meeting international standards. Currently, the "Kangshouyuan" brand ginkgo biloba extract produced by the company is not only supplied to several major domestic pharmaceutical manufacturers but also exported to countries such as Japan, South Korea, the United States, and France, enjoying a high reputation in both domestic and international markets.

Pharmaceutical Intermediate Dryer:
Vacuum drying involves heating the material to be dried under vacuum conditions, while a vacuum pump extracts air and moisture to maintain the working chamber in a vacuum state. At the same time, the moisture evaporated from the material is drawn away by the vacuum pump, significantly accelerating the drying rate and saving energy. There is virtually no temperature difference between the upper and lower parts of the dryer, and the entire machine complies with GMP pharmaceutical production requirements.
Suitable for materials with unstable states and heat-sensitive properties.
Since the interior of the vacuum box is isolated from the outside, it is suitable for recovering solvents and drying in situations where toxic or irritating gases are emitted. The recovered solvent is collected through a condenser and a buffer tank.
It belongs to static drying, so the shape of the dried material will not be damaged.

The theory of pharmaceutical intermediate dryers indicates:
1. With a constant heating temperature, increasing the vacuum degree accelerates the rate.
2. When the vacuum degree is constant, increasing the heating temperature accelerates the rate.
3. Increasing both the vacuum level and the heating temperature will significantly accelerate the rate.
4. The heating medium can be hot water or steam (steam pressure between 0.40-0.50 Mpa).
5. The inner wall of the dryer adopts arc transitions to avoid sanitary dead corners and prevent solvent condensation droplets from falling into the **layer material tray** and contaminating the material flow.

Characteristics of Pharmaceutical Intermediate Dryers:
1. Under vacuum, the boiling point of the material solution decreases, which increases the heat transfer driving force of the evaporator. Therefore, for a given amount of heat transfer, the heat transfer area of the evaporator can be reduced.
2. The heat source for the evaporation operation can be low-pressure steam, waste heat steam, or hot water circulation.
3. Minimal heat loss from the evaporator.
4. Disinfection treatment can be carried out before drying, and no impurities are introduced during the drying process, meeting GMP requirements.
5. It is a static vacuum dryer, so the shape of the dried material will not be damaged.
