During this time, spraying of the disinfectant solution is stopped, but the gas suction amount is set to 360 L / min.
The lid member 3 is raised to a predetermined height position and stopped, spraying of the disinfectant and suction of the gas are stopped, and one step is completed.
In addition, the process of (1)-(10) can be performed by an automatic driving | operation by a control mechanism (illustration omitted).
