Freeze dryer are increasingly vital for preserving the active ingredients in traditional Chinese medicinal (TCM) herbs and have become a core driver in upgrading the industry. Among their functions, the moisture-capturing ability of a freeze dryer plays a crucial role. It not only impacts the internal quality of the herbs but also directly influences the market competitiveness of TCM products.
The efficacy of TCM herbs often depends on the purity and preservation of their active ingredients. For valuable herbs such as ginseng, cordyceps, and deer antlers, even minor quality differences can significantly affect their therapeutic effects. Therefore, protecting these active substances during processing has become a key challenge for the TCM industry. Freeze dryers, as a modern drying solution for TCM, offer a way to tackle this problem, with their moisture-capturing ability being the key factor.
Moisture-Capturing Ability: The Foundation of High-Quality Freeze-Dried TCM
· Preserve 20%-30% More Active Ingredients, Enhance Efficacy
Efficient moisture removal allows for rapid and uniform dehydration at low temperatures, protecting heat-sensitive components like polysaccharides and alkaloids. Studies show that freeze-dried TCM herbs retain 20%-30% more active ingredients compared to traditional drying methods, greatly enhancing their therapeutic effectiveness.
· Optimize Appearance and Texture, Prevent Shrinkage
Precise moisture control helps maintain the original color and shape of the herbs, preventing shrinkage and deformation during drying. For example, freeze-dried reishi mushrooms not only retain their vibrant color but also closely resemble fresh mushrooms when rehydrated, making them more appealing to consumers.
· Increase Stability and Shelf Life
Effective moisture-capturing technology significantly reduces the moisture content of TCM herbs, suppressing microbial growth and extending shelf life. Freeze-dried TCM herbs can last over three years, far exceeding the storage duration of other drying methods, facilitating easier storage and transportation.
BOTH Freeze Dryers adopt advanced refrigeration technology, either through single-unit mixed cooling or dual-machine cascade cooling, to ensure rapid cooling and low condenser temperatures, resulting in strong moisture-capturing capabilities. In early trials, a TCM research institution introduced BOTH freeze dryers for high-value herbs, improving the first-pass quality rate from 80% to over 95%. Additionally, freeze-dried cordyceps produced with BOTH freeze dryers showed a 25% increase in saponin content compared to traditional drying methods, demonstrating the direct impact of moisture-capturing on enhancing TCM herb quality.
The moisture-capturing ability of freeze dryers is not only a technical guarantee for producing high-quality TCM herbs but also a driving force behind the modernization and internationalization of the TCM industry. With continued innovation and application, freeze dryers will play a crucial role in ensuring TCM product quality, contributing to the advancement of human health.
