摘要: 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 materials during molding and heating of starch-based biodegradable molded objects by means of resistance heating, dielectric heating, etc.

摘要: 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.

摘要: A mixture in the form of slurry obtained from mixing a soybean protein, sugar and water is placed between a pair of electrodes. Then, an electroconductive heating process is applied to the mixture under an applied voltage between the electrodes for a predetermined time period, thereby obtaining the sheet-like biodegradable molded article. In this method, the biodegradable molded articles have a homogeneous structure and can be prepared in a short period of time without increasing the cost of equipment of creating unfavorable working conditions.
