Description

【０００１】
【発明の属する技術分野】
本発明は、厨芥等を乾燥処理するための厨芥処理装置に関するものである。
【０００２】
【従来の技術】
従来の厨芥処理装置としては、図２５に示されるものが一般的であった。以下同図を用いて説明する。
【０００３】
１は生ゴミ等の被処理物を収容する処理容器、２はシーズヒーター等からなる加熱手段、３は処理容器１内の雰囲気温度を検出するように生ゴミの処理容器１の底裏面に配設した温度センサー、加熱手段２は温度センサー３の出力に基づき制御手段（図示せず）により所定温度で加熱制御される。４は撹拌羽根で、駆動モータ５により駆動される。撹拌羽根４，駆動モータ５によって撹拌手段を構成し、被処理物を撹拌，粉砕することにより乾燥を促進する。６は装置および被処理物を冷却すると共に処理容器１内で発生したガス（水蒸気を含む）を排出するための吸引ファンである。７はガスを排出する排気部であり、８は処理容器１と排気部７の間の排気経路に配した触媒である。
【０００４】
上記構成による作用は以下の通りである。
【０００５】
乾燥処理時間を所定時間と定め、加熱手段２の温度を立上げる予備加熱工程、制御手段により加熱手段２の温度を温度センサー３の出力に基づき所定温度で加熱制御し、撹拌羽根４で被処理物を撹拌，粉砕すると共に、吸引ファン６によってガスを排出して加熱乾燥する乾燥処理工程、吸引ファン６によって装置と被処理物の冷却を行う冷却工程の順に、所定時間経過毎に工程を移行させて一連の処理を行う。処理中、処理容器１で発生するガス（水蒸気を含む）は触媒８を通過して臭い成分を除去され、排気部７より排出される。
【０００６】
【発明が解決しようとする課題】
ところがこの種の厨芥処理装置では、乾燥処理時間を加熱の所定時間と定めていた。このため、生ゴミの量が少ない場合は過乾燥になり焦げ付くし、反対に生ゴミの量が多い場合は未乾燥となり、処理容器内に投入された生ゴミの量によって、生ゴミの乾燥状態が異なるという問題があった。
【０００７】
また、自動的に乾燥終了を判定するものも知られているが、複数のセンサーを必要とするものや、単一のセンサーで構成が簡単で経済的なものであっても判定精度にバラツキがあるという問題があった。
【０００８】
本発明は、これらの問題を解消し、単一のセンサーで使用性の高い厨芥処理装置を提供することを課題とする。
【０００９】
【課題を解決するための手段】
上記課題を解決するために本発明は、主乾燥処理工程での温度センサーの出力の出力値や時間的な変化から主乾燥処理工程の終了時点の判定と、追加乾燥処理工程の時間と温度、さらに冷却工程の時間を自動的に設定することによって、単一のセンサーのみで構成できるため、簡単かつ経済的な効果があると共に、被処理物の量や質および装置の周囲温度や電源電圧等の動作条件にかかわらず、製品の個体間のバラツキがなく乾燥不足や焦げ付き等のない適正な乾燥処理をすることが可能となる。

【００４８】

上記構成による作用は以下の通りである。
【００６８】
制御手段２２では、主乾燥処理工程で加熱手段２をオンする以前の温度センサー３の出力の変化を検出して、装置の周囲温度を推定する。すなわち、加熱手段２がオンする以前の温度センサー３の出力が単位時間当たり、急激に下降する場合は、加熱開始以前に加熱乾燥処理を行っていたと判定できるため、追加乾燥処理時間Ｔｅを長くし、逆に加熱手段２がオンする以前の温度センサー３の出力が単位時間当たり、ほとんど変化しない場合は追加乾燥処理時間Ｔｅは別手段（図示せず）にて決定して、処理を行う（図１５参照）。
【００６９】

【００７８】
制御手段２４は、図１９に示すように撹拌手段２５の動作周期を主乾燥処理工程の動作周期に対して、追加乾燥処理工程における動作周期を短くするよう制御する。これにより、加熱乾燥開始初期は撹拌周期を長めにして過剰な粉砕を抑制し、加熱乾燥処理末期での水分の蒸発を促進してさらに乾燥率を高めることができる。

【００８６】
制御手段２６では、主乾燥処理工程の開始時から加熱手段２が所定回数オン，オフした後の温度センサー３の出力が上昇から下降に変化する際に現れる最も大きな温度センサー３の値をＶ１とし、その後加熱手段２のオン，オフを繰り返し、温度センサー３の出力が上昇から下降に変化する際に現れる最も大きな温度センサー３の値をＶｎ（図示せず）としたとき、ＶｎがＶ１に対して所定の値ΔＶ以上大きくなった時点、すなわちＶｎ≧Ｖ１＋ΔＶを主乾燥処理工程の終了時点と判断し、次工程に移行するように動作する（図２２参照）。
【００８７】
なお、ΔＶは固定値であっても、他の変数から導き出されるものであってもよい。
【００８８】

  The third timing means 20 measures the time Tg from the start of the main drying process step until the heating means 2 is turned off for the first time, and outputs it to the control means 19, and the initial temperature storage means 21 is the time when the main drying process step starts. The output of the temperature sensor 3 is stored, and the stored value is stored in the control means 19.
[0060]
  The operation of the above configuration is as follows.
[0061]
  The control means 19 determines the time Te of the additional drying process, which is the next process of the main drying process, in accordance with the output of the third timing means 20, that is, the heating means 2 first starts from the start of the main drying process. When the time Tg until turning off is long, it is determined that the amount of the object to be processed is large, and the additional drying treatment time Te is also increased in combination. After the additional drying treatment for the time of Te, The cooling process is completed (see FIG. 13).
[0062]
  Further, when the output of the initial temperature storage means 21 is higher than a predetermined temperature, the additional drying processing time Te is increased. That is, when the temperature is higher than a general ambient temperature of about 40 degrees C or less before the start of heating, even before the start of heating even if the time Tg from the start of the main drying process step until the heating means 2 is turned off for the first time is short. Since it can be determined that the heat drying process has been performed, the additional drying process time Te is lengthened to act as Te ′ (not shown).
[0063]
  In this embodiment, the time Te of the additional drying process is determined in accordance with the time Tg from the start of the main drying process until the heating means 2 is turned off for the first time. Or Te may be determined, or Te may be set to a value empirically set from Tg. Te ′ may be a constant value or may be uniquely determined from the output of the initial temperature storage means 21 and Tg.
[0064]
  Note that the third timing unit 20 and the initial temperature storage unit 21 may be configured inside the control unit 19.

[0067]
  The operation of the above configuration is as follows.
[0068]
  The control means 22 detects the change in the output of the temperature sensor 3 before turning on the heating means 2 in the main drying process, and estimates the ambient temperature of the apparatus. That is, when the output of the temperature sensor 3 before the heating unit 2 is turned on rapidly decreases per unit time, it can be determined that the heat drying process was performed before the start of heating, so the additional drying process time Te is increased. On the contrary, when the output of the temperature sensor 3 before the heating means 2 is turned on hardly changes per unit time, the additional drying processing time Te is determined by another means (not shown) to perform the processing (FIG. 15).

[0077]
  The operation of the above configuration is as follows.
[0078]
  As shown in FIG. 19, the control means 24 controls the operation cycle of the stirring means 25 to be shorter than the operation cycle of the main drying process step. As a result, it is possible to suppress the excessive pulverization by increasing the stirring cycle at the beginning of the heat drying, promote the evaporation of moisture at the end of the heat drying treatment, and further increase the drying rate.
