特許文献２の都市ごみ処理用真空攪拌乾燥装置において、運転開始時には大量の高温蒸気が流量計を通過するが、乾燥完了時には僅かな量の高温蒸気しか流量計を通過しない。つまり、高感度で、ダイナミックレンジが広い高価な流量計を排蒸気経路に介設する必要がありコストがかかる。また、炉内温度計および流量計を目視して、炉内温度および蒸気流量の経時変化を計測する必要があり、作業員を常駐させる必要がある。 In the vacuum agitation drying apparatus for municipal waste treatment of Patent Document 2, a large amount of high-temperature steam passes through the flow meter at the start of operation, but only a small amount of high-temperature steam passes through the flow meter when drying is completed. That is, it is necessary to install an expensive flow meter with high sensitivity and a wide dynamic range in the exhaust steam path, which is expensive. Further, it is necessary to visually observe the in-furnace thermometer and the flow meter to measure the temporal change in the in-furnace temperature and the steam flow rate, and it is necessary to make a worker resident.

特許文献３の都市ごみ処理用真空攪拌乾燥装置において、運転開始時には大量の高温蒸気が流量計を通過するが、乾燥完了時には僅かな量の高温蒸気しか流量計を通過しない。つまり、高感度で、ダイナミックレンジが広い高価な流量計をドレイン出口に設ける必要があり、被処理物の水分量評価にコストがかかる。また、排蒸気経路の温度を、温度計を目視して計測し、乾燥が所望に達した状態を感知する必要があり、作業員を常駐させておく必要がある。 In the vacuum agitation drying apparatus for municipal waste treatment of Patent Document 3, a large amount of high-temperature steam passes through the flow meter at the start of operation, but only a small amount of high-temperature steam passes through the flow meter when drying is completed. In other words, it is necessary to provide an expensive flow meter with high sensitivity and a wide dynamic range at the drain outlet, and it is expensive to evaluate the moisture content of the object to be processed. Moreover, it is necessary to measure the temperature of the exhaust steam path by visually observing a thermometer to sense a state in which the drying has reached a desired level, and it is necessary to keep a worker resident.

脚付きの処理槽は、中空円柱状を呈し、水平に配される。
減圧手段は、処理槽に連結した排気管と、この排気管に介設し、槽内空気を排気する真空ポンプとからなり、槽内を所定の真空度に保持して水の沸点を下げる。
加熱手段は、槽外で発生させた水蒸気の熱を処理槽に伝熱して槽内の粉砕生ごみを加熱する。
攪拌回転体は、気密性を保って処理槽の左右端面に回転軸の各軸端部を軸着している。この攪拌回転体は、回転して槽内の粉砕生ごみを掻き混ぜる。
減圧下の槽内で、粉砕生ごみを加熱しながら掻き混ぜると、粉砕生ごみから水分が抜け出て排気空気とともに槽外へ排出される。これにより、粉砕生ごみが、油分を保持して乾燥処理され、茶色の粉状に変化する。なお、乾燥処理が完了すると、粉砕生ごみから水分が抜け出なくなるので、重量の変化が略ゼロになる。
排気空気中には粉砕生ごみから抜け出た水分が含まれる。凝縮手段は、この水分を冷却して復水させる。 [About claim 1]
The treatment tank with legs has a hollow cylindrical shape and is arranged horizontally.
The decompression means includes an exhaust pipe connected to the treatment tank and a vacuum pump that is interposed in the exhaust pipe and exhausts the air in the tank, and maintains the inside of the tank at a predetermined degree of vacuum to lower the boiling point of water.
A heating means transfers the heat | fever of the water vapor | steam generated outside the tank to a processing tank, and heats the crushing garbage in a tank.
The stirring rotator is axially attached to the left and right end surfaces of the processing tank with the shaft end portions of the rotation shafts maintained airtight. The stirring rotator rotates to stir the crushed garbage in the tank.
When the pulverized garbage is stirred while being heated in a tank under reduced pressure, moisture escapes from the pulverized garbage and is discharged out of the tank together with the exhaust air. As a result, the ground garbage is dried while retaining the oil, and changes to a brown powder. When the drying process is completed, the moisture does not escape from the crushed garbage, and the change in weight becomes substantially zero.
The exhaust air contains moisture that has escaped from the crushed garbage. The condensing means cools the water and condenses it.

脚を上載して、攪拌回転体、粉砕生ごみ、および処理槽の合計荷重を受ける重量センサを複数個、配設している。
この生ごみ処理装置で粉砕生ごみを真空乾燥させる際には、処理槽の中空部内に粉砕生ごみを投入して密閉し、減圧手段により槽内を所定の真空度に保持するとともに、加熱手段で槽内を所定温度に加熱しながら攪拌回転体を低速回転させる。
乾燥処理の開始初期は、粉砕生ごみから水分が多く抜け出て排気空気とともに槽外へ排出されるので、重量の経時変化は大きい。
このため、乾燥評価手段は、各重量センサが検出するセンサ別重量を加算して合計重量を検出する重量測定を第１設定時間毎（例えば、６０分毎、３０分毎、１５分毎、５分毎）に行う。
乾燥処理が進行すると、粉砕生ごみから抜け出る水分量が少なくなるので、重量の経時変化が小さくなり、前回測定した重量との差が所定値を下回る。
重量差が所定値を下回ると、乾燥評価手段は、各重量センサが検出するセンサ別重量を加算して合計重量を検出する重量測定を、第１設定時間より短く設定した第２設定時間毎（例えば、５分毎、１分毎、３０秒毎）に行う。なお、重量差が所定値を下回る時間は、処理槽内へ投入された粉砕生ごみの量や粉砕生ごみの種類によって変化する。
乾燥評価手段は、各重量センサが検出するセンサ別重量を加算して合計重量を検出する重量測定を第１設定時間毎に行う。そして、前回測定した重量との差が所定値を下回ると、各重量センサが検出するセンサ別重量を加算して合計重量を検出する重量測定を、第１設定時間より短く設定した第２設定時間毎に行う。そして、この第２設定時間毎に行う重量測定の経時変化が略ゼロになると乾燥処理が完了したと判定する。 A plurality of weight sensors for receiving the total load of the rotating rotating body, the pulverized garbage, and the treatment tank are disposed on the legs.
When vacuum drying the crushed garbage with this garbage treatment device, the crushed garbage is put into the hollow part of the treatment tank and sealed, and the tank is maintained at a predetermined vacuum degree by the decompression means, and the heating means The stirring rotator is rotated at a low speed while the inside of the tank is heated to a predetermined temperature.
At the beginning of the drying process, a large amount of moisture escapes from the crushed garbage and is discharged out of the tank together with the exhaust air.
For this reason, the drying evaluation means performs weight measurement for detecting the total weight by adding the weights for each sensor detected by each weight sensor at every first set time (for example, every 60 minutes, every 30 minutes, every 15 minutes, 5 Every minute).
As the drying process proceeds, the amount of water that escapes from the crushed garbage is reduced, so that the change with time of the weight is reduced, and the difference from the previously measured weight is below a predetermined value.
When the weight difference falls below a predetermined value, the drying evaluation means adds a weight for each sensor detected by each weight sensor to detect a total weight for each second set time set shorter than the first set time ( For example, every 5 minutes, every 1 minute, every 30 seconds). Note that the time during which the weight difference is less than the predetermined value varies depending on the amount of crushed garbage put into the treatment tank and the type of crushed garbage.
The drying evaluation means performs weight measurement for detecting the total weight by adding the sensor-specific weights detected by the respective weight sensors at each first set time. Then, when the difference from the previously measured weight falls below a predetermined value, the second set time in which the weight measurement for detecting the total weight by adding the weight for each sensor detected by each weight sensor is set shorter than the first set time. Do it every time. And when the time-dependent change of the weight measurement performed for every this 2nd setting time becomes substantially zero, it determines with the drying process having been completed.

この生ごみ処理装置は、第１設定時間より短く設定した第２設定時間毎に行う重量測定の経時変化が略ゼロになると乾燥処理が完了したと乾燥評価手段が判定する構成である。このため、乾燥処理の開始初期における過剰な重量測定を防止できるとともに、処理槽内へ投入（複数回の投入可能）された粉砕生ごみの量や種類に関わらず、乾燥処理の完了時点を精度良く判定できる。 This garbage disposal apparatus has a configuration in which the drying evaluation unit determines that the drying process is completed when the time-dependent change in weight measurement performed every second set time set shorter than the first set time becomes substantially zero. Therefore, it is possible to prevent excessive weight measurement at the beginning of the drying process and to accurately determine the completion point of the drying process regardless of the amount and type of crushed garbage that has been thrown into the treatment tank. Can judge well.

この生ごみ処理装置は、有機物分解微生物を用いていないので、有機物分解微生物の維持管理および補充は不要である。
高温蒸気の流量を計測する流量計が不要である。また、槽内温度および蒸気流量の経時変化を、温度計および流量計を目視して監視する常駐作業員が不要である。 Since this garbage disposal apparatus does not use organic matter-decomposing microorganisms, it is not necessary to maintain and supplement organic matter-decomposing microorganisms.
A flow meter that measures the flow rate of high-temperature steam is not required. In addition, there is no need for a resident worker to visually monitor changes in the tank temperature and the steam flow rate by visual observation of the thermometer and the flow meter.

シャフトが、所定位置で回転軸と直交して放射状に貫設されるとともに、槽中央以外に位置する攪拌板が、シャフトの先端に、略ハの字状および略逆ハの字状に配設されているので、乾燥処理中の粉砕生ごみが処理槽の中央部内へ集められる。
生ごみ取出口を処理槽の中央下面に形成しているので、乾燥処理が完了したごみを搬出する作業を効率良く行える。また、乾燥処理が完了したごみが処理槽の中央部内へ集まるので生ごみ取出口から容易に取り出すことができる。
更に、乾燥処理中の粉砕生ごみが処理槽の中央部内へ集まり、端に偏らないので、重量センサによる合計荷重の経時変化を精度良く計測することができる。なお、攪拌回転体がダブルパドルであるので乾燥処理中の粉砕生ごみをバランス良く静かに掻き混ぜることができるので、重量センサによる合計荷重の計測を回転状態で行うことができる。 The shaft is radially pierced perpendicularly to the rotation axis at a predetermined position, and a stirring plate located at a position other than the center of the tank is disposed at the tip of the shaft in a substantially C shape or a substantially inverted C shape. Therefore, the crushed garbage during the drying process is collected in the central part of the treatment tank.
Since the garbage collection outlet is formed on the lower surface of the center of the treatment tank, the work of carrying out the garbage after the drying process can be carried out efficiently. Moreover, since the garbage which completed the drying process gathers in the center part of a processing tank, it can take out easily from a garbage collection outlet.
Furthermore, since the pulverized garbage during the drying process collects in the central portion of the processing tank and does not deviate toward the end, it is possible to accurately measure the temporal change of the total load by the weight sensor. In addition, since the stirring rotator is a double paddle, the crushed garbage during the drying process can be gently stirred in a well-balanced manner, so that the total load can be measured in a rotating state by the weight sensor.

処理槽には、槽外で発生させた水蒸気の熱を処理槽に伝熱するための蒸気導入管、生ごみ粉砕装置と生ごみ取出口とを接続するごみ投入管、および槽内空気を抜くための排気管が連結されている。
生ごみ処理装置は、各管（蒸気導入管、ごみ投入管、排気管）と処理槽とを柔軟に連結しているので、上記各管に処理槽の重量が殆どかからない。このため、攪拌回転体、粉砕生ごみ、および処理槽の大凡の合計荷重を、脚を上載した重量センサで受けることができ、乾燥評価手段が重量の経時変化を支障なく監視することができる。 [About claim 3]
In the treatment tank, a steam introduction pipe for transferring the heat of water vapor generated outside the tank to the treatment tank, a garbage input pipe connecting the garbage pulverizer and the garbage outlet, and the air in the tank are removed. An exhaust pipe for connecting is connected.
In the garbage disposal apparatus, each pipe (steam introduction pipe, garbage input pipe, exhaust pipe) and the treatment tank are flexibly connected to each other, so that the weight of the treatment tank is hardly applied to each pipe. For this reason, the approximate total load of the stirring rotator, the pulverized garbage, and the treatment tank can be received by the weight sensor on which the legs are mounted, and the drying evaluation means can monitor the change with time of the weight without any trouble.

異物を除去した生ごみ１１を上部開口２３から粉砕器２内へ投入し、高速回転している刃２２により生ごみ１１が粉砕され、粉砕生ごみ１２となる。
この粉砕生ごみ１２は、モーノポンプ２４により一定量づつ、フレキシブルの投入チューブ２５の基部へ移送される。
投入チューブ２５の基部へ移送された粉砕生ごみ１２は、圧送ポンプ２６により処理槽３の内側槽３３の中空部３０内へ圧送される。なお、圧送中は、開閉弁２７を開弁状態にする。
そして、所定量（例えば３４８ｋｇ相当）の粉砕生ごみ１２が、内側槽３３の中空部３０内へ投入されると、開閉弁２７を閉じる。 The garbage 11 from which foreign matter has been removed is put into the pulverizer 2 through the upper opening 23, and the garbage 11 is pulverized by the blade 22 rotating at high speed to become pulverized garbage 12.
The ground garbage 12 is transferred to the base of the flexible charging tube 25 by a constant amount by the MONO pump 24.
The pulverized garbage 12 transferred to the base of the charging tube 25 is pumped into the hollow portion 30 of the inner tank 33 of the processing tank 3 by the pressure pump 26. During the pressure feeding, the on-off valve 27 is opened.
When a predetermined amount (for example, 348 kg) of crushed garbage 12 is put into the hollow portion 30 of the inner tank 33, the on-off valve 27 is closed.

大気開放弁６４を閉じ、開閉弁６３を開弁状態にして真空ポンプ６０を作動させて、中空部３０内の槽内空気を吸引して中空部３０内を所定の真空度（−５０ｋＰａ〜−９０ｋＰａ）に維持する。

(Experimental example 1)
In Experimental Example 1 shown in FIG. 3 and Table 1, the weight of the crushed garbage 12 is 48 kg at the 12th hour of operation, 44 kg at the 13th hour of operation, and the weight difference is less than 5 kg (predetermined value) at the 13th hour of operation. It became a state. For this reason, after the 13th hour of operation, the weight measurement interval was shortened every 5 minutes.

実験例１では、実際の乾燥完了は運転１３時間目であるが、重量の経時変化が略ゼロなった時点を、制御器９のマイクロコンピュータが判別するのが運転１３時間５分目であるので、運転１３時間５分目の粉砕生ごみ１２の重量算出時に乾燥処理が完了したと判別して乾燥処理を終了する様にする。
なお、運転１３時間目以降、乾燥処理を継続しても、算出される粉砕生ごみ１２の重量は、４４ｋｇと略一定値を維持することを確認した。 In Experimental Example 1, the actual completion of drying is at the 13th hour of operation, but the microcomputer of the controller 9 discriminates when the change in weight with time is substantially zero at the 13th hour and 5 minutes of operation. Then, it is determined that the drying process is completed when calculating the weight of the pulverized garbage 12 at 13 hours and 5 minutes of operation, and the drying process is terminated.
Note that it was confirmed that the calculated weight of the crushed garbage 12 was maintained at a substantially constant value of 44 kg even if the drying process was continued after the 13th hour of operation.

運転１４時間目で粉砕生ごみ１２の重量が６９．０ｋｇとなり、運転１５時間目で６４．２ｋｇとなり、運転１５時間目で重量差が５ｋｇ（所定値）を下回る状態になった。このため、運転１５時間目以降、重量測定の間隔を５分毎に短縮した。 (Experimental example 2)
In Experimental Example 2 shown in FIG. 4, after the drying process was stopped at about 3 hours after operation, about 160 kg of pulverized garbage 12 was recharged, and after the charging, the drying process was resumed.
The weight of the pulverized garbage 12 was 69.0 kg at the 14th hour of operation, 64.2 kg at the 15th hour of operation, and the weight difference was less than 5 kg (predetermined value) at the 15th hour of operation. Therefore, after the 15th hour of operation, the weight measurement interval was shortened every 5 minutes.

実験例２では、実際の乾燥完了は運転１５時間目であるが、重量の経時変化が略ゼロなった時点を、制御器９のマイクロコンピュータが判別するのが運転１５時間５分目であるので、運転１５時間５分目の粉砕生ごみ１２の重量算出時に乾燥処理が完了したと判別して乾燥処理を終了する様にする。
なお、運転１５時間目以降、乾燥処理を継続しても、算出される粉砕生ごみ１２の重量は、６４．２ｋｇと略一定値を維持することを確認した。 In Experimental Example 2, the actual completion of drying is at the 15th hour of operation, but the microcomputer of the controller 9 discriminates the time point when the change with time of the weight becomes substantially zero at the 15th hour and 5 minutes of the operation. Then, it is determined that the drying process is completed when calculating the weight of the pulverized garbage 12 at 15 hours and 5 minutes of operation, and the drying process is terminated.
In addition, it confirmed that the weight of the calculated | required pulverized garbage 12 maintained the substantially constant value with 64.2 kg even if it continued the drying process after 15 hours of driving | operation.

（実験例３）
図５に示す実験例３では、運転２時間目に、乾燥処理停止を行った後に粉砕生ごみ１２を１１０ｋｇ程度、再投入し、投入後、乾燥処理を再開した。
更に、運転４時間目に、乾燥処理停止を行った後に粉砕生ごみ１２を８５ｋｇ程度、再投入し、投入後、乾燥処理を再開した。
運転１６時間目で粉砕生ごみ１２の重量が７０．０ｋｇとなり、運転１７時間目で６８．７ｋｇとなり、運転１７時間目で重量差が５ｋｇ（所定値）を下回る状態になった。このため、運転１７時間目以降、重量測定の間隔を５分毎に短縮した。 (Experimental example 3)
In Experimental Example 3 shown in FIG. 5, about 110 kg of crushed garbage 12 was recharged after stopping the drying process at the second hour of operation, and the drying process was resumed after the charging.
Further, after the drying process was stopped at the fourth hour after the operation, about 85 kg of crushed garbage 12 was recharged, and the drying process was resumed after the charging.
The weight of the crushed garbage 12 became 70.0 kg at 16 hours of operation, 68.7 kg at 17 hours of operation, and the weight difference became less than 5 kg (predetermined value) at 17 hours of operation. Therefore, after the 17th hour of operation, the weight measurement interval was shortened every 5 minutes.

実験例３では、実際の乾燥完了は運転１７時間目であるが、重量の経時変化が略ゼロになった時点を、制御器９のマイクロコンピュータが判別するのが運転１７時間５分目であるので、運転１７時間５分目の粉砕生ごみ１２の重量算出時に乾燥処理が完了したと判別して乾燥処理を終了する様にする。
なお、運転１７時間目以降、乾燥処理を継続しても、算出される粉砕生ごみ１２の重量は、６８．７ｋｇと略一定値を維持することを確認した。 In Experimental Example 3, the actual completion of drying is at the 17th hour of operation, but the microcomputer of the controller 9 discriminates the time point when the change in weight with time is substantially zero at the 17th hour and 5 minutes of operation. Therefore, it is determined that the drying process is completed when calculating the weight of the crushed garbage 12 at 17 hours and 5 minutes of operation, and the drying process is terminated.
In addition, it confirmed that the weight of the calculated | required grinding | pulverization garbage 12 maintained a substantially constant value with 68.7 kg even if it continued a drying process after 17 hours of driving | operation.

本実施例の生ごみ処理装置Ａは、以下の利点を有する。
生ごみ処理装置Ａの制御器９のマイクロコンピュータは、各重量センサ８が検出するセンサ別重量を合算して全重量を測定する重量測定を６０分毎に行い、この測定した全重量から空重量（脚部３１を含む処理槽３＋ダブルパドル４＋モータ４３＋プーリー＋チェーンの重量）を差し引いて粉砕生ごみ１２の重量を算出する構成である。そして、測定して算出された粉砕生ごみ１２の重量と、前回測定して算出された粉砕生ごみ１２の重量との差が５ｋｇを下回ると、上記重量測定を５分毎に変更し、重量の経時変化が略ゼロになると乾燥処理が完了したと判定する構成である。
このため、乾燥処理の開始初期における過剰な重量測定を防止できるとともに、処理槽３内へ投入（１回の投入〜複数回の投入）された粉砕生ごみ１２の量や種類に関わらず、乾燥処理の完了を精度良く判定できる。 The garbage disposal apparatus A of the present embodiment has the following advantages.
The microcomputer of the controller 9 of the garbage disposal apparatus A performs weight measurement for measuring the total weight by adding the weights for each sensor detected by the respective weight sensors 8 every 60 minutes, and from this measured total weight to the empty weight. The weight of the pulverized garbage 12 is calculated by subtracting (the weight of the processing tank 3 including the leg 31 + double paddle 4 + motor 43 + pulley + chain). And if the difference between the weight of the pulverized garbage 12 calculated by measurement and the weight of the pulverized garbage 12 calculated by the previous measurement is less than 5 kg, the weight measurement is changed every 5 minutes, and the weight This is a configuration in which it is determined that the drying process has been completed when the change with time of time becomes substantially zero.
For this reason, it is possible to prevent excessive weight measurement at the beginning of the drying process, and to dry regardless of the amount and type of the crushed garbage 12 fed into the treatment tank 3 (one charge to multiple charges). Completion of processing can be accurately determined.

生ごみ処理装置Ａは、有機物分解微生物を用いていないので、有機物分解微生物の維持管理および補充は不要である。
高温蒸気の流量の経時変化を監視する必要がないので、流量計は不要である。また、槽内温度および蒸気流量の経時変化を、温度計および流量計を目視して監視する常駐作業員も不要である。 Since the garbage disposal apparatus A does not use organic matter-decomposing microorganisms, maintenance and replenishment of organic matter-decomposing microorganisms is not necessary.
Since there is no need to monitor the change in the flow rate of the high-temperature steam over time, a flow meter is unnecessary. Further, there is no need for a resident worker who visually monitors the temperature change in the tank and the steam flow rate by visually monitoring the thermometer and the flow meter.

ダブルパドル４は、回転軸４０の長さを均等分する各位置で、端面側から見ると放射状になる様に、先端に攪拌板４２を配設したシャフト４１（七本）を回転軸４０に直交して貫設する構成であり、槽中央に位置する攪拌板４２は、回転軸４０に対して平行に配設され、図示槽左方・右方に位置する攪拌板４２は、シャフト４１の先端に、略逆ハの字状および略ハの字状に配設されている。このため、乾燥処理中の粉砕生ごみ１２が処理槽３の中央部内へ集まる。 The double paddle 4 is provided with shafts (seven shafts) each having a stirring plate 42 at the tip so that the rotary shaft 40 is radially viewed from the end face at each position that equally divides the length of the rotary shaft 40. The stirrer plate 42 is arranged in a perpendicular manner, and the stirrer plate 42 located in the center of the tank is disposed in parallel to the rotating shaft 40. At the tip, it is arranged in a substantially inverted C shape and a substantially C shape. For this reason, the pulverized garbage 12 during the drying process is collected in the central portion of the treatment tank 3.

生ごみ取出口３６を処理槽３の中央下面に形成しているので、乾燥処理が完了したごみを搬出する作業を効率良く行える。また、乾燥処理が完了したごみが処理槽３の中央部内へ集まるので生ごみ取出口３６から容易に取り出すことができる。
更に、乾燥処理中に処理槽３内の粉砕生ごみ１２が、槽端に偏ることを防止できるので、重量センサ８による重量の経時変化を精度良く計測することができる。なお、攪拌回転体としてダブルパドル４を用いているので、乾燥処理中の粉砕生ごみ１２をバランス良く静かに掻き混ぜることができるので、重量センサ８による重量計測を、ダブルパドル４の回転を止めずに行うことができる。 Since the garbage outlet 36 is formed in the lower surface of the center of the treatment tank 3, it is possible to efficiently carry out the work of carrying out the garbage after the drying process. Moreover, since the garbage which completed the drying process collects in the center part of the processing tank 3, it can take out easily from the garbage removal port 36. FIG.
Furthermore, since it is possible to prevent the pulverized garbage 12 in the treatment tank 3 from being biased toward the tank end during the drying process, it is possible to accurately measure a change in weight with time by the weight sensor 8. In addition, since the double paddle 4 is used as the stirring rotating body, the ground garbage 12 being dried can be gently agitated in a balanced manner, so that the weight measurement by the weight sensor 8 is stopped. Can be done without.

粉砕生ごみ１２を搬入する投入チューブ２５は柔軟性を有する管であり、蒸気導入管５の垂直部分にフレキシブルジョイント５２を配し、排気管６の垂直部分にフレキシブルジョイント６１を配している。
つまり、生ごみ処理装置Ａは、蒸気導入管５、投入チューブ２５、排気管６と処理槽３とを柔軟に連結しているので、投入チューブ２５や管５、６の重量が処理槽３に殆どかからない。このため、ダブルパドル４、粉砕生ごみ１２、および処理槽３の大凡の合計荷重を重量センサ８で受けることができ、重量の経時変化を支障なく監視することができる。 The input tube 25 for carrying the pulverized garbage 12 is a flexible tube. A flexible joint 52 is disposed in a vertical portion of the steam introduction tube 5, and a flexible joint 61 is disposed in a vertical portion of the exhaust pipe 6.
That is, the garbage processing apparatus A flexibly connects the steam introduction pipe 5, the input tube 25, the exhaust pipe 6 and the processing tank 3, so that the weight of the input tube 25 and the pipes 5, 6 is added to the processing tank 3. It hardly takes. For this reason, an approximate total load of the double paddle 4, the pulverized garbage 12, and the treatment tank 3 can be received by the weight sensor 8, and the change with time of the weight can be monitored without any trouble.

処理槽３内の真空度を、−５０ｋＰａ〜−９０ｋＰａに維持し、処理槽３内を７０℃〜８０℃に加熱する構成である。
このため、水の沸点が適度に下がり、粉砕生ごみ１２から効率良く水分が抜け出るとともに、油分は抜け出難い。 The vacuum degree in the processing tank 3 is maintained at −50 kPa to −90 kPa, and the processing tank 3 is heated to 70 ° C. to 80 ° C.
For this reason, the boiling point of water falls moderately, water | moisture content escapes efficiently from the grinding | pulverization garbage 12, and oil is hard to escape | omit.
