Basics of Freeze Drying
Refrigeration system : Refrigeration system freezes the product and cools the coil to trap the moisture released from the frozen food in the drying chamber Heating System : Heating system provides the necessary heat required for sublimation Vacuum System : Vacuum system reduces the pressure in the drying chamber to enable boiling of water at sub zero temperatures. Working of all the systems in harmony is required to remove the water from the product when it is in iced state and trapping that moisture on the vapor trap in the form of ice.
