An interlocking mechanism 3 is provided in a machine frame 1 to transfer endless transport belts 2 and 2 in a predetermined direction with an appropriate gap A therebetween.
And the endless conveyor belts 2,
2, high frequency generators 12 and 1 as magnetic field line generators
The electromagnetic induction coils 4 and 4 connected to the electromagnetic induction coils 4 and 4 are disposed face-to-face with their respective working surfaces in contact with each other. And heat is generated by the action of lines of magnetic force generated by the electromagnetic induction coils 4, 4, and simultaneously heats both sides of the object B to be heated via the endless conveyor belts 2, 2. Further, reference numeral 6 denotes a transport port opened on one side of the machine body, 7 denotes a carry-out port, 8 denotes a take-out shooter that is hung obliquely below the carry-out port 7, and 9 denotes a take-out port, and a panel heater 11 is provided in a part thereof. The storage tray 13 is attached to prevent the temperature of the product to be heated and processed from being faded. In the case where a large number of objects to be heated are simultaneously heated, a large number of articles can be heated at a predetermined temperature in a space-saving manner by arranging the endless conveyor belts 2 in several rows in parallel. . The belt material at this time is not particularly limited, but particularly, by using a heat-resistant Teflon (registered trademark) material, the object to be heated can be easily separated from the belt without applying oil.

However, if a carbon plate is provided in place of the iron plate, the heat receiving surface is reduced due to the quality of the carbon plate. By making the temperature more uniform, the temperature of the entire heating surface can be made more uniform.

ル４，４を可動式にすることも好ましい。Instead of using the dielectric heating plates 5 and 5 as heating elements, the endless transport belts 2 and 2 are made of a material having a dielectric property, for example, a steel belt. The endless transport belts 2 and 2 themselves can be heated and processed by heating without preparing the endless transfer belts 5 and 5. The steel belt used at this time has a very thin shape, and the uniform distribution of heat is extremely difficult compared to the case of using a dielectric heating plate. Therefore, the electromagnetic induction coils 4 and 4 are movable to promote uniform distribution of temperature. Is also preferable.

The heated surfaces of the endless transport belts 2 and 4 can be clamped in the gap A between the endless conveyor belts 2 and 2 by using the magnetic force lines generated by the electromagnetic induction coils 4 and 4 and arranging the working surfaces in contact with each other. Since it is configured so that heating processing can be performed simultaneously on both sides while transferring the object B, it is possible to always and stably heat a large number of objects to be heated fully automatically without human intervention. It has a remarkable effect such as low heat loss, high heating efficiency, simple structure and universal operation by all. In particular, according to the present invention, the object to be heated B is sequentially heated while being held between the belts 2 and 2 at the same time as the transfer of the object to be heated.
