Application of freeze-drying technology in drying Dendrobium candidum
　　With the continuous development of vacuum freeze-drying technology, it has also been widely used in the field of Chinese medicinal materials. , Exert the health effects of Dendrobium officinale.
　　What is the promotion of the development of freeze-dried Dendrobium?
　　1, in terms of cost performance
　　The production type freeze dryer is expensive, and it is difficult for the growers of Dendrobium candidum to bear this part of the cost, and it is not conducive to the exploration of the technology of Dendrobium, which is not conducive to the promotion of vacuum freeze drying technology.
　　2, from the performance point of view
　　Compared with the traditional small laboratory freeze dryer, the small freeze dryer has a one-button freeze-drying function, which can get rid of the complicated manual operation of the freeze-drying process.
　　What are the benefits of vacuum freeze-drying technology in Dendrobium candidum drying?
　　1. Freeze-dried Dendrobium candidum is frozen at minus dozens of degrees and dried at low temperature under vacuum.
　　2. Freeze-dried Dendrobium candidum is a wall-breaking Dendrobium, and the active ingredients are easily dissolved.
　　3. Freeze-dried Dendrobium officinale completely breaks the wall without frying. It can be directly chewed, brewed with tea, beaten, and ground.
　　4. The quality of freeze-dried Dendrobium candidum is close to that of fresh Dendrobium candidum, the active ingredients are kept intact, and the active substances and volatile components are retained to the greatest extent.
　　5. Freeze-dried Dendrobium officinale can be directly chewed or soaked in water. Vacuum freezing kills bacteria and spores. It is safe and hygienic to take.
　　6. The moisture content of freeze-dried Dendrobium candidum can be stored for a long time without deterioration.
　　Comparison between lyophilized Dendrobium officinale and traditional dry Dendrobium:
　　1, from the appearance
　　Freeze-dried Dendrobium candidum: the appearance is lively and full, deducing the natural color, the diameter and thickness are consistent with fresh Dendrobium candidum.
　　Traditional dry Dendrobium: dried or dried Dendrobium candidum or iron maple bucket. During the drying process, the cells shrink with the evaporation of water and shrink.
　　2, from the perspective of protecting active ingredients
　　Freeze-dried Dendrobium candidum: The lyophilized Dendrobium candidum can retain white colloid, and retain its original ingredients to a great extent. Compared with ordinary traditional dried Dendrobium candidum, the content of active ingredients is 30% higher, which is close to that of fresh Dendrobium candidum.
　　Traditional dry Dendrobium: The traditional thermal method is the main method, which can easily cause the loss of biologically active substances in Dendrobium candidum and reduce the efficacy of Dendrobium candidum by 40%. The temperature during the drying process can easily destroy the active ingredients of Dendrobium candidum and affect the medicinal value and curative effect of Dendrobium candidum.
　　3. From the perspective of food safety
　　Freeze-dried Dendrobium candidum: Freeze-drying can freeze the bacteria and spores on Dendrobium candidum in the low temperature and vacuum of minus tens of degrees.
　　Traditional dry Dendrobium: It is directly dried after harvesting, and there are many pesticides and heavy metal residues. Making tea requires about 2 hours of cooking; directly powdered raw clothes, bacterial spores, pesticides and heavy metal residues are more.
