Zusammenfassung:	[Problem] To efficiently transport impurities in a dust collector to the outside. [Solution] A cleansing gas is supplied to an upper valve (52), after which the upper valve (52) is activated and an upper extraction device (51) and a tank (53) are connected. The upper extraction device (51) is activated and impurities in a dust collector (50) are transported to the tank (53), after which the upper extraction device (51) is stopped and the upper valve (52) is activated, closing the connection between the upper extraction device (51) and the tank (53), and the supply of cleansing gas to the upper valve (52) is stopped.
