Freeze dryer is the abbreviation for vacuum freeze dryerIt is a device that uses the principle of sublimation to stabilize and dry various material samples. Widely used in the research and processing of biopharmaceutical freeze-drying, traditional Chinese medicine freeze-drying, food freeze-drying, enzyme product freeze-drying, strain freeze-drying, etc. withFDWith the development of technology, freeze-drying machines have been applied in the freeze-drying processing of Cistanche deserticola, commonly known as Cistanche deserticola freeze-drying machines in the industry, which have the ability to preserve the original alkaloids of Cistanche deserticolaAmino acids, cysteine, vitamins, and mineralswaitThe advantage of maintaining the same nutritional content and being able to store for a long time at room temperature.

The freeze-drying process of Cistanche deserticola requires prior selection, cleaning, slicing, sterilization, draining, and other technological processes of the materials. The water containing Cistanche deserticola is then processedTFThe freeze-drying machine is used for low-temperature freezing crystallization to form a solid state, which is then subjected to a drying and analytical drying operation through a vacuum system and a circulation system. The solid ice in Cistanche deserticola is directly sublimated into gas in a vacuum environment without undergoing liquid state removal, leaving behind a sponge like porous water containing substance2~5%The freeze-dried material of Cistanche deserticola is processed through electronic control throughout the entire freeze-drying processPLCThe system controls temperature, vacuum operation, and determines the end of freeze-drying. The entire freeze-drying process operates in a low temperature and high vacuum environment, protecting the nutritional components and microbial active substances of Cistanche deserticola. Enzyme growth and oxidation are almost impossible, and the volatile components, heat denatured nutritional components, and aromatic components in Cistanche deserticola are lost very little. Therefore, the material properties can be maximally maintained, and the nutritional components, color, aroma, taste, shape, etc. remain basically unchanged.

The application of freeze-drying machine in the freeze-drying processing of Cistanche deserticola can preserve the original nutritional components, color, body shape, etc., with good rehydration properties and minimal water content, and can be stored at room temperature1~3Year. Resolve the issues of preserving the medicinal and nutritional components of Cistanche deserticola, facilitating storage, circulation, and use. At present, it is widely used in the processing and production of Cordyceps sinensis freeze-drying, wild mushroom freeze-drying, edible mushroom freeze-drying, Ganoderma lucidum freeze-drying, Panax notoginseng freeze-drying, ginseng freeze-drying, etc.
