A freeze dryer works in three phases with the first and most critical being the freezing phaseProper freeze drying can reduce drying times by 30.
A freeze dryer’s final phase is secondary drying adsorption during which the ionicallybound water molecules are removednbspBy raising the temperature higher than in the primary drying phase the bonds are broken between the material and the water moleculesnbspFreeze dried materials retain a porous structurenbspAfter the freeze dryer completes its process the vacuum can be broken with an inert gas before the material is sealednbspMost materials can be dried to 15 residual moisture.
A freeze dryer’s second phase is primary drying sublimation in which the pressure is lowered and heat is added to the material in order for the water to sublimateThe freeze dryer’s vacuum speeds sublimationThe freeze dryer’s cold condenser provides a surface for the water vapor to adhere and solidifyThe condenser also protects the vacuum pump from the water vapornbspAbout 95 of the water in the material is removed in this phasePrimary drying can be a slow processToo much heat can alter the structure of the material.

Freeze dryernbspandnbsplyophilizernbspare synonymous names for the same equipmentA freeze dryer executes a water removal process typically used to preserve perishable materials to extend shelf life or make the material more convenient for transportFreeze dryers work by freezing the material then reducing the pressure and adding heat to allow the frozen water in the material to sublimate.
Freeze dryers use various methods to freeze the productnbspFreezing can be done in a freezer a chilled bath shell freezer or on a shelf in the freeze dryerThe freeze dryer cools the material below its triple point to ensure that sublimation rather than melting will occurnbspThis preserves the material’s physical form.
