Upon start-up, the two-position, two-way selector valve 115 is closed, and the pump unit 112 and heater 117 are turned on. The heater 117 heats the chemical in the solution tank 11, and the thermocouple 118 monitors and feeds back the temperature of the chemical in the solution tank 111 to maintain the chemical in the solution tank 111 at an appropriate temperature. The pump device 112 sucks the chemical liquid in the solution tank 111, and sends the chemical liquid to the conduit 3 between the relief valve 114 and the check valve 113 through the check valve 113, thereby increasing the pressure in the conduit 3 between the check valve 113 and the relief valve 114. The pressure transmitter monitors the pressure of the conduit 3 in the main machine 1, when the pressure exceeds the preset pressure, the overflow valve 114 is started, so that the liquid medicine flows back to the solution tank 111 through the overflow valve 114 to form unidirectional circulation of the liquid medicine.
