シエン List of Products and Services

Our company offers contract processing for a technology called "vacuum freeze-drying," which sublimates only the moisture from materials (liquid to solid) while they are in a frozen state and dries them in a vacuum. By drying in a frozen state, we can preserve the natural tissue structure and prevent the denaturation of components. Typically, pre-freezing is done at temperatures around -50 to -40°C, but our company can lower the temperature to -60°C during pre-freezing, making it suitable for materials with a high content of polysaccharides. Especially in the food sector, we can dry while maintaining the state of "taste," "aroma," and "nutritional value," and since the drying progresses in a vacuum, we can keep the participation of the dried product to a minimum. 【Features】 ■ Extremely low temperature of "-80°C" in the cold trap cooling process ■ Stabilization of product quality and high reconstitution ability by lowering to "-60°C" during pre-freezing *For more details, please download the PDF or feel free to contact us.

We offer contract processing of materials (from liquid to solid) using the technology of "vacuum freeze-drying (FD)," which sublimates only the moisture while the material is in a frozen state and dries it in a vacuum. Compared to conventional thermal drying, the residual moisture is extremely low, making it less likely for spoilage due to moisture to occur. Since drying is performed in a vacuum, there is almost no bacterial contamination from air, allowing for long-term storage after drying. Additionally, the areas that evaporate become hollow, resulting in a porous dried product, which has excellent rehydration properties when water is added. 【Features】 ■ Extremely low temperature of “-80°C” during the cold trap cooling process ■ Stabilization of product quality and high rehydration properties by lowering the temperature to “-60°C” during pre-freezing *For more details, please download the PDF or feel free to contact us.

• Freeze Dryer

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.

• Vacuum Dryer
• Freeze Dryer

What is freeze-drying (lyophilization)? It is a technology that dries materials (from liquid to solid) by sublimating moisture while in a frozen state under vacuum, allowing for minimal changes in the structure due to heat or oxidation, thus keeping changes in nutritional components to a minimum. Additionally, because there is little residual moisture, spoilage is less likely to occur, enabling long-term storage without the need for preservatives. 【Features】 ■ The cold trap cooling process at an extremely low temperature of "-80°C" ■ Stabilization of product quality and high reconstitution ability by lowering to "-60°C" during pre-freezing 【Example: Cosmetics Field】 By applying vacuum freeze-drying treatment to liquid raw materials such as collagen and beauty serums, which have poor stability over time, products can be stored in a dried state, eliminating or reducing the need for preservatives. Therefore, by pursuing preservative-free products through vacuum freeze-drying processing, it strongly impresses users as a reliable product and allows for differentiation from conventional cosmetics. *For more details, please download the PDF or feel free to contact us.*
