The steam enters by the journals of theboiler, which can be tilted by a simple swivelarrangement in order to be easily emptied forcleaning purposes and for removing the cookedmass. The entrance of the steam, which takesplace through one of the journals, is so arranged MACHINES EMPLOYED IN FINISHING. 73 as to allow steam or water to enter at will —the steam to boil the mass, the water to cool it,whilst a mechanical agitator, placed above theapparatus, constantly stirs it.
