As shown in FIGS. 2 and 4, the dehumidifier 20 is disposed inside the housing 121 and at least one around the input port 122. In this embodiment, the dehumidifier 20 is placed both inside the housing 121 and around the input port 122. That is, the powder dissolving device 100 includes a plurality of dehumidifiers 20. Dehumidifier 20 contains silica gel. However, the dehumidifier 20 may be made of a material other than silica gel.

As shown in FIGS. 3 and 4, a portion of the dehumidifier 20 is held inside a holder 30 having air permeability. The holder 30 is housed together with the powder 10 inside the housing 121.

The holder 30 is made of, for example, a ball-shaped sponge. A space for accommodating the dehumidifier 20 is provided in the center of the holder 30. The holding body 30 has a size such that it does not get caught up in the screw 125. The holder 30 is not limited to a sponge, and may be a bag having air permeability and moisture resistance, such as a non-woven bag, a nylon plastic bag, or an aluminum bag. The holder 30 does not allow each of the powder 10 and the silica gel powder to pass through.

Since the holder 30 is housed together with the powder 10 inside the casing 121, when the movable part 126 stirs the powder 10, the holder 30 is also stirred together with the powder 10, so that the powder inside the casing 121 is 10 can be brought into contact with the holder 30.
