作が繰り返される。(1) Close the first stop valve, retract the piston in the horizontal cylinder, raise the piston in the vertical cylinder, and
Close the stop valve. (Fig. 3 (1)) (2) In this state, the first stop valve is opened for a certain period of time. Then,
A certain amount of powdery raw material falls from the hopper into the horizontal cylinder. Since the horizontal cylinder is cooled by the cooling means, the raw material in the horizontal cylinder is prevented from melting and remains in powder form. ((2) in FIG. 3) (3) Close the first stop valve and move the piston in the horizontal cylinder forward. Then, the raw material in the horizontal cylinder falls into the vertical cylinder in powder form. Since the vertical cylinder is heated by the heating means, the raw material dropped in the vertical cylinder is melted and liquefied. ((3) in FIG. 3) (4) The second stop valve is opened and the piston of the vertical cylinder is lowered. Then, the melted and soft creamy raw material in the vertical cylinder falls into the raw material melting machine without applying a large load to the driving means of the piston and without being fused to the inner surface of the vertical cylinder. ((4) in FIG. 3) (5) Subsequently, the state returns to the state of (1) above, and thereafter, the same operation is repeated.
