率良く行われない課題があった。<Problem to be solved by the invention> However, generally, food waste produced from school lunch centers etc. has a very high moisture content of 80% to 90%, so food waste with a high moisture content is directly transferred to fermenters. When fermentation starts, the temperature of the food waste in the tank does not rise to the optimum fermentation temperature, even if you heat it with a heater from the outside and stir it, due to the high water content. There was an issue where fermentation was not carried out efficiently.

The hot air is installed so that it is in direct contact with the bottom of the storage tank, and a blower for blowing out the hot air into the storage tank is installed at the top of the storage tank, and the intake side of the blower is connected to the top of the heat generation furnace through a duct. A circulation duct is connected between the storage tank and the hot air generation furnace for returning the air in the storage tank to the hot air generation furnace, and a stirring mechanism is disposed within the storage tank.

熱源６には電気ヒータ或は燃焼バーナ等が使用される。Reference numeral 1 denotes a storage tank for storing organic waste, which has a curved bottom, and has an input hatch 2 at the top and a takeout hatch 3 at the bottom, which can be opened and closed. A hot air generating furnace 4 is provided below the bottom of the storage tank 1 in contact with the bottom of the storage tank 1. The hot air generating furnace 4 is formed by inserting a heating source 6 into a furnace body 5, and the heating source 6 is an electric heater, a combustion burner, or the like.
熱風発生炉４内の熱風が収容槽１の底に直接接するよう
に、つまり収容槽１の底壁が炉体５の上壁を兼ねるよう
にして取付けられる。It is installed so that the hot air in the hot air generating furnace 4 comes into direct contact with the bottom of the storage tank 1, that is, the bottom wall of the storage tank 1 also serves as the top wall of the furnace body 5.

In addition, since the heat R generation furnace 4 is arranged in contact with the bottom of the storage tank 1, the thermal conductivity to the storage tank 1 is good, and the storage tank 1 efficiently receives conductive heat from the hot air generation furnace 4. 7. A blower 7 for blowing hot air downward into the tank is attached to the upper side wall of the storage tank 1, and a duct 8 is connected to the intake side of the blower 7. is connected to the upper part of the hot air generating furnace 4. Further, an exhaust duct 15 for exhaust is provided at the upper part of the storage tank l.

Therefore, the hot air generated in the hot air generating furnace 4 is blown out from the upper part of the storage tank 1 downward into the tank by the action of the blower 7, and the air in the tank is returned to the hot air generating furnace 4 through the duct 9.

１３により回転駆動される。An organic waste stirring mechanism 10 is disposed inside the storage tank 1 . This stirring mechanism 10 is constructed by attaching a large number of stirring blades 12 around a rotating shaft 11 that is horizontally supported in a tank, and a sprocket 14 fixed to an end of the rotating shaft 11.
is connected to a motor 13 via a chain, and is rotationally driven by this motor 13.
次に、上記構成の有機廃棄物処理装置の動作を説明する
。Next, the operation of the organic waste treatment apparatus having the above configuration will be explained.

It is opened and put into the storage tank 1. And motor 13
is activated to rotate the stirring blades 12 of the stirring mechanism 10 to stir the organic waste. At the same time, the heating source 6 of the hot air generating furnace 4
is started to start heating, and the blower 7 is operated to blow hot air from the hot air generating furnace 4 downward into the storage tank 1, and the air in the tank is circulated between the hot air generating furnace 4 and the hot air generating furnace 4. .
これにより、槽内の有機廃棄物は攪拌されながら熱風を
受けて加熱されていく。また、熱風発生炉４が収容槽１

熱が良好に収容槽１の底部に伝導し、収容槽１はその伝
導熱によっても直接的に効果的に加熱される。このため
、有機廃棄物が含水率の非常に高い生ごみであっても、
比較的均一に効率良く加熱され、その含水率は、例えば
８０％から２０％前後にまで迅速に低下し、その体積も
５０％前後まで収縮し、生ごみは乾燥していく。As a result, the organic waste in the tank is stirred and heated by the hot air. In addition, the hot air generating furnace 4 is connected to the storage tank 1.
Since the heat source 6 is mounted in direct contact with the bottom of the storage tank 1, the heat of the heating source 6 is well conducted to the bottom of the storage tank 1, and the storage tank 1 is directly and effectively heated by the conducted heat. For this reason, even if the organic waste is food waste with a very high moisture content,
It is heated relatively uniformly and efficiently, its moisture content quickly decreases from, for example, 80% to around 20%, its volume also shrinks to around 50%, and the garbage dries.
生ごみ等の有機廃棄物を完全に乾燥処理する場合は、そ
のまま処理を続け、完全に乾燥した状態で、処理装置を
停止し、取出し用ハツチ３を開いて乾燥した有機廃棄物
を取出す。When organic waste such as food waste is to be completely dried, the treatment is continued, and when the waste is completely dry, the processing equipment is stopped, the removal hatch 3 is opened, and the dried organic waste is taken out.
また、有機廃棄物を発酵処理する場合は、含水率が適当
な値になったところで、処理装置の運転を停止し、昇温

し、別の発酵槽へ入れる。In addition, when fermenting organic waste, the operation of the processing equipment is stopped when the moisture content reaches an appropriate value, and the heated and appropriately dried organic waste is taken out from the storage tank 1. Pour into another fermenter.
なお、別の発酵槽を使用しない場合、上記のような乾燥
処理が終了した後、槽内に発酵菌を入れ、加熱源６の加
熱を調整して、槽内の温度を最適な発酵温度に維持しな
がら発酵を行うこともできる。In addition, if a separate fermentation tank is not used, after the drying process as described above is completed, put fermentation bacteria into the tank and adjust the heating of the heating source 6 to bring the temperature inside the tank to the optimal fermentation temperature. Fermentation can also be carried out while maintaining the temperature.

A blower for blowing out hot air into the storage tank is installed at the top of the storage tank, and the intake side of the blower is connected to the top of the hot air generating furnace via a duct. A circulation duct that returns the air to the hot air generating furnace is connected between the storage tank and the hot air generating furnace, and a stirring mechanism is installed inside the storage tank, so that the organic waste thrown into the tank is In addition to being heated by receiving hot air while being stirred, the hot air generator is installed in direct contact with the bottom of the storage tank, so the heat from the heating source is well transmitted to the bottom of the storage tank, and the storage tank absorbs the conducted heat. It is also heated effectively. Therefore, even if the organic waste is food waste with a very high moisture content, it can be quickly dried using hot air and direct heating from the bottom of the storage tank.
