A blower driven by the thermal edge flow was shown to promote the freeze-drying processes. First, the pressure rise due to the thermal edge flow was confirmed by using an accumulation unit and the pressure rise of 5Pa was obtained. Next, the effect of the blower for sublimation from frozen material was confirmed by using frozen sponges containing some amount of water. The necessary time for drying by using the blower was roughly half of that without the blower, and the efficiency of the sublimation was shown to depend on the combination of the effects of the blower and the surrounding vacuum pressure.
