Traditional Chinese Medicine Powder Freeze Dryer

Freeze dryer manufacturers are here to sort out the traditional Chinese medicine powder freeze dryer. The process of Chinese medicine freeze-dried powder is that the Chinese medicine decoction (or Chinese medicine extract, Chinese medicine extract) is prepared and boiled to obtain the decoction, and then it is placed on a plate (it can also be freeze-dried in a vial), and then placed in a freeze dryer for low temperature. Freeze into solid ice crystals, freeze for about 3 to 8 hours at the crystallization temperature below -50°C or below -45°C, and then heat up to a safe sublimation temperature for low-temperature sublimation drying. The type of container and the monitored temperature and vacuum index of the freeze dryer are used to comprehensively judge the end point of sublimation drying. After the sublimation drying is completed, transfer to secondary drying. According to the characteristics of traditional Chinese medicine, the secondary drying is generally 0~40 degrees Celsius, and the time is usually more than 3 hours, usually 3~10 hours.

After the analysis and drying, the freeze dryer automatically enters the heat preservation stage, and the pressure rise test is performed before discharging to ensure that the freeze-drying effect is achieved. Finally, the freeze-dried Chinese medicine products with a water content of about 3% or 1% are obtained, and then the traditional Chinese medicine soup is obtained after low-temperature crushing. agent or ointment or extract lyophilized powder. The entire vacuum freeze-drying process is in a low temperature and vacuum environment, and it is in a safe temperature range that can be monitored, which can effectively ensure that the material will not be oxidized, degraded, or chemically reacted.
