What Is The Cold Trap Device Of The Freeze Dryer?

Apr 22, 2019 The cold trap is a device for capturing moisture in the freeze-drying process. Theoretically, the lower the temperature of the cold trap, the stronger the water trapping ability of the cold trap, but the lower the temperature of the cold trap, the higher the cooling requirement, the higher the machine cost and the running cost.

cold trap used to collect the moisture that leaves the frozen product. The collector condenses out all condensable gases, i.e; the water molecules, and the vacuum pump removes all non-condensable gases. The collecting system acts as a cold trap to collect moisture leaving the frozen product. It is important to understand that the vapor pressure
