  • Freeze Dryer Basics: What Is a Freeze Dryer and How

    2002-8-22 · ­ Freeze-drying, or lyophilization, is like 'suspended animation' for food. You can store a freeze-dried meal for years and years, and then, when you're finally ready to eat it, you can completely revitalize it with a little hot water. Even after all those years, the taste and texture will be pretty much the same. That's some trick!

    FREEZE DRYING PROCESS. Freeze drying is the drying of an already frozen product in a vacuum below the “triple point” (6.2 mbar = 4.6 torr). Here, water will only be present in two phases: ice and vapour. The vacuum allows the ice to turn directly into vapour without first passing through the water stage, in a sublimation process.
