Dendrobium candidum has the unique effect of relieving depression. Especially in the summer, if you use Dendrobium to soak the water, you can not only regulate the stomach, strengthen the resistance, but also cool off.

Fresh dendrobium flowers can not be placed for a long time, it is easy to oxidize and turn red, resulting in a large loss of internal nutrients, which need to be dehydrated and dried in a short time.

Drying process of sarcophagus: conventional baking and drying, temperature and humidity are not easy to control, there will be a speed of evaporation of the internal moisture of the dry material to the surface less than the evaporation rate of the surface, then the water film forming the fluid boundary layer on the surface of the dried material will be When it is broken, local dry cracking will occur on the surface of the dried material, and then it will expand to the entire outer surface to form surface hardening. At the same time, the temperature and humidity control during the drying process is not good. It is easy to ferment the Dendrobium candidum. The internal anthocyanins, polysaccharides, and saponins will be lost to some extent, causing the flowers to turn orange.

The heat pump dryer is equipped with a box-type drying room, and the drying cycle is about 8~10h. The air source heat pump dryer controls the small temperature difference air supply mode through the intelligent control program, reduces the temperature and humidity climb gradient of the drying room, and can accurately control the temperature and humidity during the drying process. In the early stage, the low-temperature drying mode is adopted, the temperature is controlled at 30°C-50°C, and the humidity is controlled at 50%~60%, so that the humidity of the surface of the stone flower is not too low, and there is no local dry crack on the surface of the flower, resulting in surface hardening. phenomenon. At the same time, the temperature gradient of the inner and outer surfaces of the material should not be too large by reasonable temperature and temperature drainage. The solute inside the material has reverse osmosis during the drying process, so that the water as solvent can migrate the surface of the material alone to overcome the loss of solute. The phenomenon preserves the original fragrance of the material, and the color does not change color. In the low-temperature and wet drying process, local overheating does not occur, and surface moisture evaporation is uneven, resulting in shrinkage, which ensures the original shape of the flower. In the late drying stage, 70 ° C high temperature and low humidity baking is used to shape the flower, so that the dried flower can produce a unique fragrance during the hot water brewing process.
