The output of the manual shut-off valve 17 is connected to a resistance thermometer 16. The output of the resistance thermometer 16 is connected to a filter 11. By setting up filters 2 and 11, the steam can be filtered. To reduce internal impurities in the steam and prevent contamination from entering the drying chamber 19 and drying chamber 214, the output end of filter 211 is connected to electric regulating valve 27, the output end of electric regulating valve 27 is connected to electric regulating valve 415, the output end of electric regulating valve 415 is connected to drying chamber 19, drying chamber 19 is connected to electric regulating valve 38 through a pipe, the output end of electric regulating valve 38 is connected to thermal resistor 16, the output end of thermal resistor 16 is connected to check valve 10, the output end of check valve 10 is connected to manual shut-off valve 25;

The output end of the temperature controller 13 is connected to the drying chamber 14.

[0017] There are six check valves 2 18, which are respectively connected to the secondary oven, tertiary oven, quaternary oven, quinary oven, sixth oven and seventh oven. The six check valves 2 18 are connected to the manual shut-off valve 3 17 through pipelines.

[0019] In use, steam enters the pipeline by opening the manual shut-off valve 1, then passes through the filter 2 and the electric shut-off valve 3, and then enters the drying chamber 14 through multiple electric regulating valves 4. After passing through the check valve 18, it then passes through the manual shut-off valve 17, the thermal resistor 16, the filter 11, the electric regulating valve 7, and the electric regulating valve 4 15 in sequence before entering the drying chamber 9 for use. Finally, it is discharged into the hot water tank 12 for collection through the electric regulating valve 8, the thermal resistor 6, and the manual shut-off valve 5 in sequence.
