Dendrobium freeze-dried powder is produced throughSFDTraditional Chinese Medicine Freeze Drying Machine EquipmentBy utilizing the principle of sublimation and following the processing requirements of Dendrobium freeze-dried powder, the hydrated Dendrobium raw slurry is subjected to low-temperature freezing and vacuum sublimation drying to remove moisture. It has the ability to preserve various nutritional components, pharmacological substances, and color, aroma, and taste of the original dendrobium without significant changes. It has good rehydration properties and can be stored for a long time at room temperature. The quality of Dendrobium freeze-dried powder has strict requirements for the processing technology of Dendrobium freeze-drying and the selection of traditional Chinese medicine freeze-drying machines.

Processing technology of Dendrobium freeze-dried powderThe entire processing process from fresh raw materials to freeze-dried powder is as follows:
1Screening fresh and high-quality dendrobium raw materials;

2, proceedRemoving impuritiesCleaning and organizing；
3Regarding Dendrobium officinale strips2cmLeft and right segmentation;

4Breaking, crushing, and pulping the dendrobium segments;

5Filter the dendrobium slurry to leave a clear liquid;

6Concentrate at room temperature through molecular sieves;

7Put the concentrated dendrobium solution into a tray:1cmAbout thickness;

8Vacuum freeze-drying（SFDTechnical requirements for freeze-drying process;

9Low temperature crushing and sieving;

10Obtain freeze-dried powder of Dendrobium officinale for testing, weighing and packaging.

According to the freeze-drying process flow and technical requirements of Dendrobium officinale freeze-dried powder, a traditional Chinese medicine freeze-drying machine is selected for processing and production. The equipment technology and functional requirements are as follows:
1Temperature control range of partition:-50~80℃；

2Extreme condensing temperature:-70~-75℃；

3Ultimate vacuum degree:2.6PA;

4At room temperature~-40Cooling time at ℃: ≤60min

5Box, partition, condenser material:304stainless steel;

6Capable of setting and modifying freeze-drying process data, as well as recording and storing freeze-drying data;

7Freeze drying curve query and password permission management function;

8Equipped with heating rate and vacuum fine adjustment control functions, as well as various freeze-drying protection functions;

9It has remote operation and monitoring functions, as well as a one click defrosting function.

The selection of traditional Chinese medicine freeze-drying machine needs to meet the freeze-drying process requirements of dendrobium freeze-dried powder, which is widely used in dendrobium planting bases and dendrobium processing enterprises for freeze-drying development and production. It is also suitable for freeze-drying various medicinal materials, such as Huangjing freeze-drying, Tianma freeze-drying, Lingzhi freeze-drying, ginseng freeze-drying, Rehmannia glutinosa freeze-drying, cordyceps freeze-drying and other processing and production.
