Freeze drying technology,also known as vacuum freeze drying,is a process in which the water in a material is frozen to a solid state under vacuum conditions and then sublimated directly without passing through the liquid phase.Since the solid component is partially supported by solid ice,the sublimation of the ice leaves pores in the dried residue.This helps to maintain the integrity of the biological and chemical structure of the product and its activity.We have 17 years of experience in lyophiliser manufacturing and have developed three product lines: Laboratory Freeze Dryer,Pilot Freeze Dryer and Custom Industrial Freeze Dryer.
