What is freeze-drying?

Sublimating moisture while keeping it in a frozen state for drying! It is an excellent drying method with minimal color and component changes.

On this homepage, we introduce the drying method called "freeze-drying." Our product rapidly freezes the material at temperatures below -30°C, gradually reducing the pressure to create a vacuum state, and dries the material by sublimating the moisture while it remains in an ice state. This method is also known as vacuum freeze-drying. It is said to be an excellent drying method with minimal color and component changes. The drying time is also reported to be almost the same as that of hot air (warm air) dryers. Please take a look at our homepage. 【Features】 ■ Rapidly freezes the material at temperatures below -30°C ■ Gradually reduces pressure to create a vacuum state ■ A method that dries the material by sublimating the moisture while it remains in an ice state ■ Minimal color and component changes, making it an excellent drying method ■ Drying time is almost the same as that of hot air (warm air) dryers *For more details, please refer to the PDF document or feel free to contact us.
