Yingtai: Advantages of Using Freeze Dryers to Produce Freeze-Dried American Ginseng  

American ginseng, a precious medicinal herb with both culinary and therapeutic uses, is highly favored by consumers for its nourishing yet non-heating properties. In recent years, with the increasing demand for health products, the American ginseng market has continued to expand. However, traditional processing methods such as hot-air drying or sun-drying present several issues, including high drying temperatures and prolonged exposure to air, which can damage active and effective components, compromising the quality and efficacy of American ginseng. To address these problems, vacuum freeze-drying technology has been adopted to effectively preserve its beneficial constituents.  

A freeze dryer removes over 90% of moisture at low temperatures, enabling long-term storage without deterioration. For American ginseng, which is rich in heat-sensitive active ingredients such as ginsenosides, polysaccharides, and peptides, freeze-drying not only maximizes the retention of these valuable compounds but also enhances product quality and added value.  

Process flow for freeze-drying American ginseng using a freeze dryer:

Fresh raw material → Cleaning → Slicing → Spreading on trays → Freeze-drying → Packaging  

By employing vacuum freeze-drying technology for American ginseng processing, not only are its active ingredients and original form effectively preserved, but its shelf life is also extended, increasing its market value and better meeting consumer demand for high-quality health supplements.  

The SFD Pilot Freeze Dryer is not only suitable for processing freeze-dried American ginseng but can also be used for other medicinal herbs such as freeze-dried cordyceps, freeze-dried ginseng, and freeze-dried dendrobium.
