Vacuum freeze-drying
working principle:
Vacuum freeze-drying, also known as sublimation drying. The principle is to freeze the material so that the water contained in it becomes ice cubes, and then sublimate the ice under vacuum to achieve the purpose of drying.
Vacuum freeze-drying is referred to as freeze-drying, which freezes wet materials or solutions to a solid state at a relatively low temperature (﹣10 ° C ~ ﹣50 ° C), and then makes the water in it directly under liquid state without using liquid (1.3 ~ 13 Pa) Drying technology that sublimates into a gaseous state and dehydrates the material.
Application:
Use to dry various liquids or pastes, such as traditional and western medicine, food, biological products, chemicals, health foods, food additives, etc., especially suitable for dry materials, high viscosity, easy large-scale formation, or thermoplastic, Sensitivity, or non-drying / not suitable for spray drying of these materials, a vacuum belt dryer is a good choice.Compatible with other machine outputs such as color, solubility and storage time physical properties.
Equipment advantages:
1.Automatic, canalized, continuous, continuous feeding and discharging, drying, crushing under vacuum state, making vacuum state
2. Processing cost is 1/3 of traditional process, reducing labor cost
3.Adjustable water content
4. Good performance of heat sensitive materials, easy to clean
5. After 30-60mins continuous discharge, the collection rate reaches 99%
6.Overcome the difficulties of high viscosity and drying of various liquids and solids
7. Automatic cleaning (CIP), according to GMP requirements
