Vacuum freeze drying machine

• 
  SSFD series vacuum freeze dryer

  Freeze drying is to directly transform the moisture or other organic solvents in the material from a solid state into a gas through sublimation, thereby removing the moisture or other solvents in the material. Freeze drying must be frozen at low temperature and carried out in a vacuum state, so it is also called vacuum freeze drying. Sublimation refers to the process in which a solvent changes directly from a solid state (such as water, like dry ice) to a gaseous state without passing through the liquid state. The product obtained by freeze-drying is called lyophilisate. Traditional drying will cause the material to shrink and destroy cells, while the freeze-dried material structure will not be destroyed and can effectively retain the biological and active integrity of the product.

  SSYD series vacuum freeze dryer

  Freeze-drying is different from other drying methods. It directly converts the moisture or other organic solvents in the material from a solid state into a gas through sublimation, thereby achieving the purpose of removing moisture or other solvents.
