The inside of the heating plate is provided with a heating medium passageway through which a heating medium can flow. A heating medium tank is connected to the heating medium passageway through a heating medium feeding passageway and a circulating pump. Warm water or steam are fed to the heating medium passageway. The warm water or steam have the temperature which can volatilize a medium from the heating medium tank or can volatilize the injected solution. A vacuum pump is connected to the closed container.
