  • Constitution Of High-Frequency Heating (AREA)

Abstract

PURPOSE: To prevent a preheating temperature from dropping in case of preheating a resin tablet in a microwave field, by spraying a cooling fluid on the tablet.
CONSTITUTION: A resin tablet 12 is placed on a pair of roller electrodes 11 and a high frequency is applied to between the electrodes 11 and an upper electrode 13 for pre-heating treatment. A cooling fluid P such as dry air is blown toward the tablet 12 to keep its external temperature lower than its internal temperature, which allows to raise the upper limit of preheating temperature by above 5 or more than 10°C compared with a conventional method.
