A blower driven by the thermal edge flow was shown to be possible to use for freeze drying. First, the pressure rise by the thermal edge flow was confirmed by using an accumulation unit. The pressure rise of 5Pa was given. Next, the effect of the blower for sublimation from frozen material was confirmed by using frozen sponges containing some water. The necessary time for drying by using the blower was roughly half compared with a drying time by not using the blower and the effect of the blower for sublimation depended on the surrounding vacuum pressure.
