Vacuum freeze dryer machine and lyophilizer that can apply to biological, pharmaceutical, chemical and food as well as laboratory research and samples preservation.
Freeze drying also known as lyophilization, is a low temperaturedehydrate process typically use to preserve perishable materialsor make the material more convenient to storage.
Freeze drying removes water by freezing the material, and thenreduce its surrounding pressure, proper add heat to allow thefrozen water in the material to sublime directly from solid phaseto gas.
Because during the process, no liquid phase involves, andmaterials temperature always in minus. So, freeze drying has lessimpact on product physical and chemical properties. Which resultdried products maximum keep the original features.
Freeze drying works extremely well on almost all industries.
