The application of freeze-drying machines in the Chinese herbal medicine industry has become an important technical means to promote the modernization of traditional Chinese medicine, and its core value is reflected in the following aspects:

1、 Efficient retention of thermosensitive active ingredients

Low temperature process protects active substances: The freeze-drying machine freezes medicinal materials in a low temperature environment below -40 ℃ and directly sublimates the water under vacuum conditions, avoiding the damage of high temperature to thermosensitive components such as ginsenosides, flavonoids, volatile oils, etc.

Significantly improving drug stability: Taking honeysuckle as an example, the traditional drying process reduces the content of chlorogenic acid to below 1.5%, while the freeze-drying process can increase its retention rate to over 2.8%, far exceeding the pharmacopoeia standard of 12. After freeze-drying treatment, the retention rate of salvianolic acid IIA in the compound increased by 35%, and the absorption rate in the human body accelerated by 1.5 times.

2、 Optimize product form and quality

Maintaining natural characteristics: After freeze-drying, traditional Chinese medicinal materials can retain their original color, aroma, and porous structure, and have rehydration properties.

Convenient for formulation production: Traditional Chinese medicine extract can be freeze-dried to make instant powder or block like substance, which facilitates subsequent crushing and formulation molding.

3、 Significantly extend shelf life and safety

Inhibition of microbial reproduction: Freeze drying reduces the moisture content of medicinal herbs to below 3%, achieving a super long shelf life of 2-3 years without the need for preservatives, far exceeding the traditional shelf life of 6-12 months for decoction pieces.

Reduce pollution risk: Low temperature operation throughout the process reduces the possibility of heavy metal residue.

4、 Expand high value-added application scenarios

Development of health care products: products such as cakes and traditional Chinese medicine health tea can not only retain active ingredients such as collagen and amino acids, but also solve the problem of burnt taste caused by traditional cooking, which meets the needs of modern health consumption25.

5、 Adapt to diverse production needs

Full chain coverage capability: From laboratory research and development (1L small-scale) to industrial mass production (900L batch), LYO series and other freeze-drying equipment can flexibly match different production capacity requirements.

Overall, freeze-drying machines are reshaping the paradigm of traditional Chinese medicine processing with their advantages of "zero thermal damage" and "ultra long preservation". With the upgrading of intelligence and cost optimization, this technology is expected to become the core driving force for breaking through quality barriers in the internationalization process of traditional Chinese medicine.
