What is freeze-drying?
Low-temperature drying is possible! It is useful for vegetables and fruits that lose nutrients starting around 40°C.
Freeze-drying, also known as vacuum freeze-drying, is the process of sublimating frozen materials under vacuum conditions. In freeze-drying, drying occurs in an environment of 10 to 100 Pa (1/10,000 of atmospheric pressure, which is approximately 1013 hPa or 101,300 Pa). Water cannot exist as a liquid at pressures below about 600 Pa, so drying under this pressure allows for sublimation. 【Features】 - The water originally present in the frozen material becomes ice. - When drying occurs under vacuum, the ice turns into water vapor (sublimation). - The ice disappears as it becomes water vapor, leaving holes where the ice was. - If the water returns to its original location, it can restore the material to its original state. *For more details, please refer to the PDF document or feel free to contact us.
