PURPOSE:To lessen temperature variability in a packed material, by equipping partially heating parts having wave guides irradiating different positions in the transfer direction making a packed material come close to before and behind an inverting part to invert a supporting material and in the direction perpendicular to the transfer direction with microwave. CONSTITUTION:A material to be sterilized by microwave is packed into a container or bag to give a packed material, which is stored in a supporting material A made of a material capable of transmitting microwave, irradiated with microwave by microwave oscillators 10A1-10A4, heated and sterilized while being transferred. Partial heating parts 1A1 and 1A2 having wave guides 11A1-11A4 to irradiate different positions in the transfer direction making the packed material come close to before and behind an inverting part 1B to invert the supporting material A and in the direction perpendicular to the transfer direction. Consequently, temperature variability in the packed material in microwave heating sterilization of continuous type can be lessened, deterioration of qualities by overheating is prevented and short-time uniform heating is made possible. |
