Pursuit of preservative-free! Collagen and beauty serums can be stored in a dry state!
We offer contract processing of materials (from liquid to solid) using the technology of "vacuum freeze-drying (FD)," which sublimates only the moisture while keeping the material in a frozen state and dries it in a vacuum. Since there is minimal structural change due to heat or oxidation, it is possible to keep changes in nutrients and other components to a minimum. Drying is performed while the material remains frozen, so it does not experience high temperatures like in thermal drying. Therefore, decomposition, alteration, and discoloration that can occur in conventional thermal drying are less likely, and changes in nutrients and other components due to heat are minimized. Additionally, there is no denaturation of proteins or loss of vitamins, allowing for the maintenance of nutrients and components. By pursuing preservative-free products, we provide users with reliable materials! This also differentiates us from conventional cosmetics! 【Features】 ■ Extremely low temperature of "-80℃" in the cold trap cooling process ■ Stability of product quality and high recoverability achieved by lowering to "-60℃" during pre-freezing *For more details, please download the PDF or feel free to contact us.

Company information
What is important in vacuum freeze-drying processing is not only the performance of the machine but also the appropriate preparation of the material and the settings and operation of the machine, in other words, "human skill." At Sien Co., Ltd., we perform contract processing of vacuum freeze-drying with "human skill" that maximizes the performance of the machine. Please feel free to consult us if you have any requests.
