*Working principle

Supercritical CO2 fluid drying technology is a new type of drying method developed using the special properties of supercritical CO2 fluid. It has a remarkable feature in the drying process, that is, the process of removing water or other solvents. Establish a phase balance relationship between carbon dioxide and the material to be removed. There is no microstructure change (such as collapse of the pores) caused by the capillary surface tension on the dried material, so particles with small particle size and uniform distribution can be obtained.

*Features

1. Can be carried out under mild temperature conditions, especially suitable for the drying of heat-sensitive materials;
2. It can effectively dissolve and extract large molecular weight, high boiling point and difficult volatile substances;
3. The organic solvent can be easily removed from the solid material by changing the working conditions.

*Application

1. Material development and application areas: preparation of aerogels;
2. Pharmaceutical industry: drying of antibiotics;
3. Food industry: treatment of bacteria in raw materials.
