Further, in the above-mentioned embodiment, it is assumed that the melting tank 2 is filled with a predetermined number of drums 1 ... However, the water temperature in the dissolution tank 2 may be raised in advance to a temperature exceeding the melting temperature of yellow phosphorus, and the drum can 1 may be carried into the dissolution tank 2 for processing. By doing so, the processing speed can be increased.

In this embodiment, the case where the drum can 1 is filled with yellow phosphorus has been described as an example. However, in addition, the filling material in the drum can 1 is taken out by the suction nozzle 72 and the drum can 1 is reused. It can be applied if not.
