[0018]

According to the structure of the charging port of the carbonizing chamber or the carbonizing apparatus of the present invention, even when a large amount of flammable organic substances are packed in the carbonizing chamber having stirring blades therein, flammable organic substances are charged. There is no trouble that the stirring blade is locked by being pinched near the hole, and the combustible organic matter can be stably incinerated or carbonized. Further, the inner lid blocks heat in the carbonization chamber and hinders heat conduction to the outer lid, so that the outer lid does not become abnormally high and the opening and closing of the outer lid can be easily and safely performed. In addition, the trouble of ending the operation with no combustion or non-carbonization is reduced, and the fuel is not wasted. Further, since the stirrer blade is not locked by the combustible organic matter, there is no need to attach an indicator light, a buzzer or the like at the time of locking.

Further, if the inner lid is pressed against the outer lid via the inner lid pressing member, the gap between the carbonization chamber and the inner lid can be almost eliminated, and a tar-like or sticky material derived from a flammable organic substance can be obtained. The object is prevented from entering between the inner lid and the outer lid during the carbonization process. Therefore, when removing the lid of the coal outlet in order to take out the processed material (carbide) after the carbonization operation, the inner lid can be easily removed without being fixed to the mouth frame. In addition, the state where the combustible organic matter is boiled between the inner lid and the outer lid, or near the input port frame or the coal outlet port frame is less likely to occur.
