What Temperature Does A Freeze Dryer Work at Kay John blog

What Temperature Does A Freeze Dryer Work. When liquids other than water are present, the temperature and pressure are maintained below the eutectic point. The chart below shows the necessary pressure and temperature values of different phases of water. Freeze dryers work by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to change directly to a vapor (sublimate). Next, the freeze dryer pulls the air out of the chamber, and the trays are slightly heated. The first step in freeze drying is to freeze the product. Frozen material spread on the heated trays is subjected to drying by maintaining the temperature and pressure lower than the triple point of water (when only water is present) i.e., 0.0098°c and 4.58 mm of hg respectively.
