2. Description of the Related Art For environmental protection, the industry has refrained from producing and using molded articles for packaging from materials that are difficult to decompose, such as plastics and foams. Instead, molded products made of materials that are easy to decompose, such as pulp, and are environmentally friendly have come to be used.

As shown in FIG. 1, a pulp molding machine generally used for manufacturing a molded body for paper quality packaging is provided with a drivable pulp suction mold 73 in a machine body frame body 7. A plurality of molding members 731 are projected on the upper surface of the pulp suction mold 73, and below the pulp suction mold 73 is provided a pulp storage container 71 that can move up and down. A pulp raw material is stored in the pulp storage container 71, an upper die drive device 721 for vertically moving the upper die 72 is provided above the upper die 72, and a bottom portion of the upper die 72 is provided at the bottom of the upper die 72. A plurality of projecting molding members 722 are formed. A plurality of air holes are provided on the surface of the molding member 722,
The ingress and egress of air produces suction or thrust. A conveyor belt extending outward is provided on one side of the pulp suction mold 73 in the machine frame body 7. Such a pulp molding machine operates as follows: The pulp suction mold 73 is rotated so that the molding member 731 is on the lower surface, the pulp container 71 is raised, and the molding member 731 is immersed in the pulp raw material. . When an appropriate amount of pulp raw material is sucked onto the surface of the molding member 731, the pulp container 71
And the pulp suction mold 73 is inverted. Subsequently, the upper die driving device 721 drives the upper die 72 to lower it, and the molding member 722 is pressed against the molding member 731.
By this pressure contact, the pulp on the molding member 731 is molded, and then the molding member 722 sucks the pulp molding.
This pulp molded body is moved to the conveyor belt 74 by raising the upper mold 72 and moving in the horizontal direction, and the conveyor belt 74 performs the next step (drying in a dryer, air drying).
Be transported to.

A pulp molding is automatically processed by the pulp molding apparatus as described above. However, after the pulp molded body is molded, it is immediately heat-dried or air-dried. However, since the pulp molded body contains a large amount of water, it takes a long time to dry, and It has the drawback that the density of the fiber of the product is low and the production efficiency is poor.
