The traditional Chinese medicine freeze-drying machine utilizesFDfreeze-drying technologyIn various traditional Chinese medicine vacuum freeze-drying processing equipment, it includes freeze-drying of various Chinese medicine extracts, Chinese medicine soup liquids, Chinese medicine preparations, Chinese medicine raw materials, etc. Among them, bear bile containsUrsodeoxycholic Acid、Cholic acid and deoxycholic acid, etcutensilIt has the functions of clearing heat, detoxifying, calming the liver, and improving visionclasseffect.At present, the SFD traditional Chinese medicine freeze-drying machine is used to process bear bile juice to obtain freeze-dried bear bile juice powder, which can effectively preserve the original molecular structure, pharmacological components, and microbial active ingredients without significant changes, solving the problems of drug component loss in traditional drying methods.

The traditional Chinese medicine freeze-drying machine uses the principle of sublimation to pre process bear bile and freeze it in situ at a low temperature of -50 ℃ for 180 minutes to crystallize. Then, the freeze-drying equipment undergoes a drying stage, with a drying temperature range of -30~10 ℃ and a vacuum degree controlled at 30PA ± 3. The heating rate is controlled (under the guidance of the engineer), and the drying time is 10-15 hours. In this stage, 90% of the flowing water is removed. After the completion of a drying stage, the process enters analytical drying. The temperature range for analytical drying is 10-40 ℃, and the vacuum degree is controlled at 25PA ± 3. The heating rate is controlled (under the guidance of the engineer), and the drying time is about 15 hours. Before the drying is completed, a pressure rise test is conducted to determine the drying effect. After completion, a freeze-dried powder of bear bile juice with a water content of about 1% is obtained. Due to the continuous operation and processing in low temperature and vacuum environment, the physical structure of substances and microorganisms in bear bile is not damaged or undergoes oxidation reactions. It has good rehydration properties and can be stored at room temperature for a long time after sealing.

Traditional Chinese Medicine Freeze Drying Machine EquipmentWith the technical advantages of vacuum freeze-drying to maintain the original nutritional components and properties of materials, it has been widely used in bear farms and bear bile processing enterprises, as well as in the processing of various Chinese medicinal materials such as crocodile blood freeze-drying, leech freeze-drying, deer antler freeze-drying, ginseng freeze-drying, cordyceps freeze-drying, etc.
