  • Method and device for manufacturing biodegradable molded objects
    Patent number: 6136255
    Abstract: A voltage is applied to a feeder plate (29) from a power source section (2) including an alternating power source for dielectric heating, whereby an electric field in a direction crossing a direction in which a mold (8) is moved is applied to an incoming plate (28) which is not in contact with the feeder plate (29), so that molded object materials (9) are heated and expanded. By doing so, arc discharge caused by contact of the mold with an electrode is prevented from occurring during the heating and molding of a biodegradable molded object by dielectric heating.
    Type: Grant
    Filed: August 29, 1998
    Date of Patent: October 24, 2000
    Assignee: Nissei Kabushiki Kaisha
    Inventors: Sadamasa Ando, Taizo Karasawa, Toshitaka Haruta, Akio Ozasa, Takayuki Kurisaka, Tsutomu Oowada, Shinji Tanaka
  • Method of manufacturing molded baked snacks
    Patent number: 6063422
    Abstract: Using a metal mold (8) having an insulating section provided with vapor release sections, pressure outside the metal mold (8) is reduced, and heating is performed while releasing vapor produced thereby through the vapor release sections. This can prevent insulation breakdown caused by condensation of large amounts of vapor produced by ingredients during molding and heating of molded baked snacks by means of resistance heating, dielectric heating, etc.

  • Method for manufacturing biodegradable molded articles
    Patent number: 5639518
    Abstract: A raw material formed by a mixture of, for example, soybean protein and water, is extruded by an extruder. Then, high-frequency electroconductive heating is performed by placing the material between a pair of electrodes and applying a voltage between the electrodes. As a result, a biodegradable molded article is obtained. In this method, biodegradable molded articles having a uniform structure are manufactured in a short period of time without increasing the cost of equipment or adversely affecting the working environment.
