Supercritical dryer introduction

Supercritical dryer has two drying processes: CO2 fluid or ethanol liquid drying.

Drying method using the characteristics of supercritical fluid

It is a equipment that uses supercritical fluid to dry materials with the advantages of both gas and liquid properties.

Supercritical drying process

Supercritical drying technology is a new chemical technology that has developed rapidly in recent years. It is a new type of drying method developed by using the characteristics of supercritical fluids.

In the supercritical state, the medium fluid penetrates into the interior of the object to be dried, exchanges with solvent molecules gently and quickly, replaces the solvent, and then changes the operating parameters to change the fluid from the supercritical state to the gaseous state, from the raw material to be dried Released in the middle to achieve a drying effect.

Supercritical drying aerogel

Aerogel, as a typical product representative of supercritical drying, is an ultra-low-density porous solid material with nano-particles or polymer molecules as the skeleton. Used in aerospace, catalysis, adsorption and other fields.


  • The air/liquid interface of the dried medium disappears, and there is no liquid surface tension;
  • The drying process is gentle, and the damage to the material structure caused by the drying stress is avoided to a greater extent;
  • Because supercritical fluid has high diffusion coefficient characteristics, its drying speed is faster;
  • The drying and desolventizing processes are all carried out under high pressure, and the desolventizing process also has a sterilization effect.


  • It can be carried out under mild conditions, so it is especially suitable for drying heat-sensitive materials;
  • It can effectively dissolve and extract high molecular weight, high boiling point and hardly volatile substances;
  • The organic solvent can be easily removed from the solid material by changing the operating conditions.


Drying of silicon oxide, zirconium oxide, heat-sensitive animal and plant products.
