- 処理槽に入れた生ごみを加熱手段により加熱する生ごみ処理方法であって、
前記加熱手段の加熱温度に最高加熱温度と最低加熱温度とを設定する処理と、
前記生ごみの処理開始により、前記加熱手段に最高加熱温度を設定して加熱処理を開始し、その最高加熱温度での加熱処理で前記生ごみの水分蒸発によって生じる前記処理槽内の処理温度の上昇及び下降の検知に基づき、前記処理温度のピーク値を検出する処理と、
前記最高加熱温度で加熱処理を維持し、前記ピーク値を経て前記処理温度が下降した後、前記処理温度にピーク値が生じた際に前記最高加熱温度より低い加熱温度に変更して加熱処理を維持し、ピーク値が生じる度に低い加熱温度に変更して前記加熱処理を行う処理と、
を含むことを特徴とする生ごみ処理方法。 - 前記加熱処理は、前記処理温度の下降レベルが所定値以内の場合には、前記加熱温度を所定温度だけ低い加熱温度に変更し又は前記加熱温度で維持し、前記処理温度の下降レベルを超えた場合には、現在の加熱温度を所定温度だけ高い加熱温度に変更させて加熱処理を行うことを特徴とする請求項1記載の生ごみ処理方法。
- 前記最低加熱温度に前記加熱温度が到達し、その加熱温度を維持させた際に、前記処理温度が前記ピーク値を超えて上昇したことが検知されたとき、前記乾燥処理を終了させることを特徴とする請求項1記載の生ごみ処理方法。
- 前記ピーク値の検出の際に用いられた前記処理温度の下限温度を基準値とし、この基準値から所定温度だけ上昇した処理温度を前記加熱処理の終了点に設定したことを特徴とする請求項1記載の生ごみ処理方法。
- 処理槽に入れた生ごみを加熱手段により加熱する生ごみ処理装置であって、
前記処理槽内の前記生ごみを加熱する前記加熱手段の加熱温度を検出する第1の温度検出手段と、
前記加熱手段で加熱される前記処理槽内の前記生ごみの処理温度を検出する第2の温度検出手段と、
前記加熱手段の加熱温度として最高加熱温度及び最低加熱温度とともに、これら最高加熱温度と最低加熱温度との間で所定温度だけ下降又は上昇させる加熱温度を設定し、前記生ごみの処理開始により前記加熱手段に最高加熱温度を設定して加熱処理を開始し、その最高加熱温度での加熱処理で前記生ごみの水分蒸発によって生じる前記処理槽内の処理温度の上昇及び下降の検知に基づき、前記処理温度のピーク値を検出し、該ピーク値の検出の後も前記最高加熱温度で加熱処理を維持し、前記ピーク値を経て前記処理温度が下降した後、前記処理温度にピーク値が生じた際に前記最高加熱温度より低い加熱温度に変更して加熱処理を維持し、ピーク値が生じる度に低い加熱温度に変更して加熱処理を行う制御手段と、
を備えたことを特徴とする生ごみ処理装置。
