[0002]

2. Description of the Related Art Most of kitchen garbage, such as garbage, discharged from homes, restaurants, food factories, etc., contains a large amount of water, and therefore it requires a great deal of labor to carry and dispose of it. Moreover, especially in the summer, it decomposes in a short time and gives off a bad odor, which is a factor that significantly deteriorates the surrounding environment.

The most effective method for treating such troublesome kitchen waste is to directly heat and remove the contained water, whereby the kitchen waste is reduced in volume, weight and putrefaction. Can be achieved at the same time,
Some devices for performing such processing have already been proposed (Japanese Patent Publication No. 4-45401 and Japanese Patent Publication No. 4-401).
74120, etc.). In addition to such a drying treatment, there is also proposed a device for decomposing kitchen waste made of organic matter into harmless water and carbon dioxide by utilizing the power of biotechnology such as spoilage bacteria (Japanese Patent Laid-Open No. 4-238886). Japanese Patent Laid-Open No. 5-22
No. 0463).

And turn on the power to drive the blower dry indoor air is sucked out after being sucked into the blowing machine, sent to the heat exchange chamber side in the upper casing, where it is preheated through the heat exchange chamber After that, it is sent to the deodorization / heating chamber side , where it is burned and the organic components are decomposed and deodorized. afterwards,
This exhaust gas becomes combustion exhaust gas and is sent again to the heat exchange chamber side , and after exhaust gas from the drying chamber side sent later is preheated, it is released to the outside air. Therefore, the odorous gas exhausted from the drying chamber side is not released to the outside as it is, and the surrounding environment is not adversely affected. Further, when the air in the drying chamber is exhausted by the blower in this way, the negative pressure in the drying chamber causes the outside air to be sucked in from the air intake formed in the lower casing and pass through the frame, and through the air introduction pipe. after a is sent to the indoor deodorizing and heated, where it is heated warm air Te, it is sucked into the drying chamber, wherein after drying the garbage drying chamber, as described above again, is evacuated by the blower odorless Will be processed. On the other hand, the kitchen waste exposed to the warm air thus sent is dried after the water content is removed, and the volume is greatly reduced and reduced, and then appropriately discharged. At this time, the dried kitchen garbage has a considerable amount of heat, so before opening this, open the damper and open the bypass pipe, so that the outside air (cold air) taken into the frame will not change in pressure. It can pass through the low bypass pipe side and flow directly into the drying chamber to cool the kitchen garbage that is high in heat in a short time.
