The pressure transmitter 46 arranged upstream of the flow meter 5 can monitor the pressure in the pipeline, and when the pressure in the material lifting pipe section 42 reaches a set value, the third control valve 93 is opened, and the material liquid flows through the material lifting pipe section 42 and is conveyed to the material feeding section 43.
