Carbonization treatment device (patent No. 10--0151694), vacuum carbonization means and gas combustion means for carbonizing and converting food waste into basic particles of soil improving agent in a closed space maintained at a constant temperature. Vacuum carbonization apparatus (No. 10-0231238) consisting of cleaning means, a heat generating portion for heating the carbonization furnace, and a heat insulation case constituting a heating chamber, which supplies electric energy as a heating pipe to heat the food waste dry type A carbonization device (Publication No. 10-2006-0086003) and the like are known, and as shown in FIG. 1 of the accompanying drawings, a drying furnace 3 is provided. The organic gas is dried and carbonized to the carbonization furnace 4, and the generated gas is introduced into the combustion furnace 5 through the discharge pipe.In the first ignition of the combustion furnace 5, fuel such as RPF fuel or ion economic oil is used. After that, the gas and steam generated in the drying furnace 3 and the carbonization furnace 4 and introduced into the combustion furnace 5 are used as fuels, and when the ignition furnace 5 is ignited, the temperature rises. Fuel is used, and combustion of harmful gases and steam generated during drying and carbonization of organic materials is used as fuel in the first and second combustion chambers of the combustion furnace 5, and the gas and steam are burned in the first and second combustion chambers. The high heat generated while being discharged to the communication tube (6) is a high temperature heating the inside of the carbonization furnace (4) by the communication tube (6) passing through the center of the carbonization furnace (4) to communicate the solids of the organic matter in the communication tube (6) Carbonization is also carried out by the heat released through Also known is a carbonization treatment apparatus (No. 10-0503490).

The cylinder 111 is made of a high-temperature stainless steel sheet of about 25 millimeters thick, the upper portion forms a porous plate, and preferably has a rail moving structure at the bottom as needed. The moving structure of the rail constitutes a rail on the bottom side of the carbonization processing chamber 110, and is formed of a cylinder 111 on which wheels are rolled, and detailed description thereof is omitted.

The handle 115 applies a kind of catch handle (catch, such as a submarine) as it is, has excellent sealing force, maintains considerable internal pressure, and has considerable durability.
