Tea culture has a long history in China, with a rich variety of teas including green tea, black tea, oolong tea, white tea, and more. With the evolution of times, tea appreciation has evolved beyond mere gustatory pleasure to embody a lifestyle and spiritual essence, while traditional tea practices have gradually extended into modern tea innovations—particularly tea powder and tea bag products. For fast-paced consumers, traditional tea-brewing methods are often cumbersome. Freeze-drying technology addresses this by producing freeze-dried tea powder that meets modern demands for convenience while preserving the aroma, flavor, and quality of tea.
As tea bases serve as the foundation for most beverages—such as milk tea, a widely popular example—the tea industry continues to innovate and expand. The production of freeze-dried tea powder begins with extracting and concentrating tea liquid, which is then frozen into a solid state. This freezing process locks in the concentrated tea's components. The frozen material is then placed into a freeze-dryer for vacuum freeze-drying. Under vacuum conditions, the solid water content sublimates directly into a gaseous state, bypassing the liquid phase. This is achieved by leveraging the triple-phase changes of water under low temperature and pressure: the boiling point of water is altered in a vacuum, allowing solid ice to sublimate into vapor with minimal heating.
The entire process occurs at low temperatures, ensuring that heat-sensitive compounds and nutrients in the concentrated tea remain intact. The resulting freeze-dried tea powder boasts excellent rehydration properties, dissolving effortlessly in both hot and cold water.
Compared to traditional hot-air-dried tea products, freeze-dried tea retains significantly higher levels of nutrients. Additionally, it maintains the original tea's quality and flavor over extended storage periods, providing robust support for the diversified development of tea products. This innovative approach not only meets contemporary consumer needs but also opens new avenues for tea's application in modern lifestyles.
