"No preservatives or additives are needed anymore." Freeze-drying allows for the preservation of ingredients in their original state! We accept prototype requests!
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.*

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.
