  • Patent number: 8876510
    Abstract: In a molded body production device, a release agent injection means applies a release agent onto an upper punch surface by injecting the release agent toward the upper punch surface in a state that an upper punch is located above an upper end surface of a molding die, and applies the release agent onto a lower punch surface and an inner circumferential surface exposing above the lower punch surface by injecting the release agent toward the lower punch surface in a state that the lower punch surface is located into the cavity and below the upper end surface of the molding die, before the molding material is filled into the cavity. This makes it possible to prevent the molding material from bonding to the upper punch surface, the lower punch surface and the inner circumferential surface defining the cavity.

Electrostatically charged powder is sprayed upwardly onto the interior surface of a mold surrounded by a mask. The mask includes a shield located adjacent to but spaced from the shear edge of the mold. Additionally, the mask includes a vacuum duct located beneath the shield. While air is drawn into the vacuum duct air is either blown through the slot defined between the shield and the mold shear edge or air is pulled into the slot so as to prevent oversprayed powder from coming into contact with and adhering to the shear edge of the mold. There is no enclosure surrounding the mold cavity other than the mask because rising heated air currents entrap and maintain the cloud of sprayed powder interiorly of the mold cavity and the surrounding mask. Any oversprayed material escaping from the cavity is caught in the vacuum duct and carried to a powder collector.

The surface of the product is treated with a fluid, which could be for coloring or flavoring purposes, but is advantageously e.g. an edible acid adapted to react with protein in the product to form a cohesive surface and enable the use of a separate skin to be avoided. The mold includes a permeable wall, for example of sintered stainless steel, through which the fluid can be introduced. In a preferred embodiment the wall is defined by a hollow cylinder disposed in a non permeable housing containing the fluid. An end cap closes one end of the cylinder and a plunger compresses the material to form the product. At the same time additional fluid is injected through a nozzle into the housing, to cause a corresponding quantity of fluid to pass through the cylinder wall and treat the surface of the product.
