Description

本発明は、製造工程で発生する製造ロスによるパンの他、店頭で売れ残って廃棄されるパンや調理時に発生し或いは食べ残し等によって発生するパン屑などの廃棄パンを粉砕、乾燥して、家畜用飼料等に用いることができる粉粒体とする廃棄パンの処理方法及び処理装置に関する。  In addition to bread due to production loss generated in the production process, the present invention pulverizes and dries bread that is left unsold at a store and discarded, or bread that is generated during cooking or left over, etc. The present invention relates to a processing method and a processing apparatus for waste bread, which is a granular material that can be used for feed for food.

近年、外食産業の発達にしたがって企業から排出される食品ゴミの量が増加の一途を辿っており、この食品ゴミの増加を規制して地球環境を守るために、2001年5月から食品リサイクル法が施行され、リサイクル率を最低20%まで高めることが義務づけられている。  In recent years, the amount of food waste discharged from companies has been increasing with the development of the restaurant industry. In order to protect the global environment by regulating the increase in food waste, the Food Recycling Law has been in effect since May 2001. Is enforced and it is obliged to raise the recycling rate to at least 20%.

そして、日本人の食生活の変化に伴ってパンの消費量も年々増加しており、それに伴って、上記外食産業で提供される食べ残しのパン屑の他に、コンビニエンスストアなどで売れ残りにより廃棄されるパン、サンドイッチ等のパンを用いた商品を製造する際に発生するパン屑の廃棄量も年々増加の一途を辿っており、これら廃棄パンやパン屑の処分が問題となっている。  The consumption of bread has been increasing year by year due to changes in the Japanese diet. Along with this, in addition to the uneaten bread crumbs provided by the restaurant industry, it has been discarded due to unsold goods at convenience stores. The amount of crumb waste generated when producing products using bread such as baked bread and sandwiches has been increasing year by year, and disposal of these baked bread and crumbs has become a problem.

そこで、家庭から出る調理前後の生ゴミを粉砕処理してスラッジ状に飼料化又は肥料化するシステムが提案され、このシステムによると、生ゴミを粘稠なスラッジ状に粉砕し、このスラッジに凝集剤を添加した後、高圧圧送装置により高圧フィルタープレスに圧送して微粉砕状の粘稠な飼料とする生ゴミのリサイクルシステムが提案されている(例えば、特許文献1参照)。  Therefore, a system has been proposed that grinds raw garbage before and after cooking from households into feed or fertilizer in the form of sludge. According to this system, the raw garbage is crushed into viscous sludge and agglomerated in this sludge. There has been proposed a system for recycling garbage that is added to a high pressure filter press by a high pressure pumping device after adding the agent to form a finely ground viscous feed (for example, see Patent Document 1).

In addition, a rotating blade is provided on the upper surface of the mesh body to finely pulverize the bread granule carried into the vertical passage from the primary drying passage side into a powder having a predetermined diameter or less.

最後に、請求項8に記載の廃棄パンの処理装置は、請求項3乃至請求項7の何れか1項に記載の廃棄パンの処理装置において、二次乾燥通路内の中心部に中空回転軸を配設してこの中空回転軸内に二次乾燥通路外から熱風供給パイプを通じて熱風を送り込むことにより二次乾燥通路内を加熱するように構成していると共に、該中空回転軸の外周面に廃棄パンの粉粒体をこの二次乾燥通路の出口側に向かって送り出す複数枚の攪拌搬送板を長さ方向に間隔をとって突設していること特徴とする。  Finally, the waste pan processing apparatus according to claim 8 is the waste pan processing apparatus according to any one of claims 3 to 7, wherein a hollow rotary shaft is provided at a central portion in the secondary drying passage. And is configured to heat the inside of the secondary drying passage by sending hot air from the outside of the secondary drying passage through the hot air supply pipe into the hollow rotation shaft, and on the outer peripheral surface of the hollow rotation shaft. A plurality of agitation transport plates for sending the waste pan powder particles toward the outlet side of the secondary drying passage protrude from the lengthwise direction.

上記のように構成したので、投入ホッパを通じて一次乾燥通路の一端部内に廃棄パンを投入すると、廃棄パンは、一次乾燥通路内に設けた中空回転軸に突設している多数の破砕羽根からなる破砕手段によって細かく破砕されると共に一次乾燥通路内で加熱されて廃棄パンに含まれている水分が水蒸気となり、加熱空気の一部と共に一次乾燥通路外に排出される。上記破砕羽根によって廃棄パンを破砕する際に、廃棄パンは極めて軽量であるので、破砕羽根の回転力によって廃棄パンを破砕、分断しようとしても、廃棄パンは破砕羽根と共に回転して破砕することが困難となる。このため、破砕羽根に刃状部分を設けてパンを切断すると共に破砕羽根の先端面と一次乾燥通路の内面とによって廃棄パンを擦り潰して破砕するようにしている。  Since it comprised as mentioned above, when a waste pan is thrown in in the one end part of a primary drying channel | path through a charging hopper, a waste pan consists of many crushing blades protrudingly provided in the hollow rotating shaft provided in the primary drying channel | path. It is finely crushed by the crushing means and heated in the primary drying passage and the water contained in the waste pan becomes water vapor, and is discharged out of the primary drying passage together with part of the heated air. When the waste pan is crushed by the crushing blade, the waste pan is extremely lightweight. Therefore, even if the crushing blade is crushed and divided by the rotational force of the crushing blade, the waste pan may rotate and crush with the crushing blade. It becomes difficult. For this reason, the crushing blade is provided with a blade-like portion to cut the pan, and the waste pan is crushed and crushed by the front end surface of the crushing blade and the inner surface of the primary drying passage.

さらに、一次乾燥通路内の廃棄パンの収容量、即ち、通路内の空間に対する収容密度が小さいと、廃棄パンは殆ど擦り潰し処理されにくいので、一次乾燥通路内の一端部側、即ち、廃棄パンの搬送始端部側に通路を一次的に閉止する遮蔽板を設けておき、この遮蔽板を閉止することによって、該遮蔽板と投入ホッパの投入口間の通路内を投入ホッパから供給される廃棄パンの滞留室に形成し、多量の廃棄パンを一旦、この滞留室内に充満させた状態にして破砕羽根の回転によって攪拌しながらその攪拌による大形の廃棄パンの破砕処理と該破砕羽根の先端面と通路の底面とによる破砕処理とを繰り返し行う。  Furthermore, if the storage capacity of the waste pan in the primary drying passage, that is, the storage density in the space in the passage is small, the waste pan is hardly crushed, so one end side in the primary drying passage, ie, the waste pan. A shielding plate that temporarily closes the passage is provided on the transport start end side, and by closing this shielding plate, the inside of the passage between the shielding plate and the charging hopper is discarded from the charging hopper. A crushing process for a large waste pan by stirring and rotating the crushing blade while a large amount of waste pan is once filled in the dwelling chamber and the tip of the crushing blade is formed The crushing process by the surface and the bottom of the passage is repeated.

滞留室内での廃棄パンの破砕処理が所定時間行われたのち、遮蔽板を開放すると、処理された廃棄パンのパン片や大小の粉粒体は一次乾燥通路1内を他端に向かって搬送される。中空回転軸の外周面には、破砕されたパン片や粉粒体の送り出し方向に噴出口を向けている噴射ノズルを長さ方向に適宜間隔毎に突設しているので、この噴射ノズルから熱風を噴出させることによって既にある程度細かく破砕された軽量なパン片や粉粒体は一次乾燥通路内の他端排出口に向かって吹き飛ばされるように搬送させられる。さらに、上記破砕羽根における一次乾燥通路の排出口側に向けている面を搬送傾斜面に形成しておくことによって、廃棄パンのパン片や粉粒体を該破砕羽根の回転に従ってその搬送傾斜面で一次乾燥通路の排出口側に向かって搬送することができると共にその搬送途上においても該破砕羽根の刃状部分によりパンを切断すると共に該破砕羽根の先端面と通路の底面とにより廃棄パンの破砕処理を行う。  After the crushing process of the waste pan in the staying chamber is performed for a predetermined time, when the shielding plate is opened, the bread piece and the large and small powder particles of the processed waste pan are transported in the primary drying passage 1 toward the other end. Is done. On the outer peripheral surface of the hollow rotating shaft, there are provided injection nozzles that project the outlets in the direction of delivery of the crushed bread pieces and powder particles at appropriate intervals in the length direction. Light-weight bread pieces and powders already crushed to some extent by blowing hot air are conveyed so as to be blown off toward the other end discharge port in the primary drying passage. Furthermore, by forming a surface facing the discharge port side of the primary drying passage in the crushing blade on the conveying inclined surface, the bread inclined pieces and powder particles of the waste pan are rotated according to the rotation of the crushing blade. Can be transported toward the discharge port side of the primary drying passage, and even during the transportation, the pan is cut by the blade-shaped portion of the crushing blade and the waste pan is separated by the front end surface of the crushing blade and the bottom surface of the passage. A crushing process is performed.

また、一次乾燥通路内の加熱空気によって廃棄パンのパン片や粉粒体が加熱され、その内部に含まれている水分が一次乾燥通路内に蒸散して含水率を低下させる。その上、噴射ノズルから噴出する上記熱風によって廃棄パンのパン片や粉粒体がさらに加熱されると共に、その熱風が多孔質状態のパン片や粉粒体の微細な隙間を流通してこれらのパン片や粉粒体を内部からも加熱し、従って、含まれている水分の除去作用が一層効果的に行われて短時間で能率よく所定の含水率まで乾燥処理することができる。  In addition, the bread pieces and powders of the waste bread are heated by the heated air in the primary drying passage, and the moisture contained in the waste pans into the primary drying passage to reduce the moisture content. In addition, the hot air blown from the spray nozzle further heats the bread pieces and powders of the waste bread, and the hot air circulates through the fine gaps between the porous bread pieces and powders. The bread pieces and powders are also heated from the inside, so that the contained water can be removed more effectively and can be efficiently dried to a predetermined moisture content in a short time.

こうして、一次乾燥通路内で破砕処理され且つ含水率を低下させられたパン片や粉粒体は、一次乾燥通路の他端排出口から垂直通路を通じて二次乾燥通路の他端部内に送り込まれる。この際、垂直通路内に所定大きさのパンの粉粒体を通過させる一定大きさの多数の小孔を設けてなる網状体を張設しておくと共にこの網状体の上面に一次乾燥通路側からこの垂直通路内に搬入されたパンの粉粒体をさらに細かく粉砕する回転刃を設けておくことによって、一次乾燥通路側からこの垂直通路内に送り込まれたパン片や粉粒体は、全て、飼料として他の配合物に混合するのに適した均一な径の粉粒体とされて二次乾燥通路内の他端部内に投入される。  In this way, the bread pieces and powders that have been crushed in the primary drying passage and reduced in water content are fed from the other end discharge port of the primary drying passage into the other end of the secondary drying passage through the vertical passage. At this time, a mesh body provided with a large number of small holes of a predetermined size for allowing a bread granule of a predetermined size to pass through the vertical passage is stretched, and the primary drying passage side is provided on the upper surface of the mesh body. From the primary drying passage side, all the bread pieces and granules fed into the vertical passage are provided by providing a rotary blade for further finely pulverizing the bread granule carried into the vertical passage. Then, it is made into a granular material having a uniform diameter suitable for mixing with other blends as feed, and is put into the other end of the secondary drying passage.

この二次乾燥通路内にも上記一次乾燥通路と同様に中空回転軸が設けられてあり、この中空回転軸の外周面に廃棄パンの粉粒体を該二次乾燥通路の出口側に向かって送り出す複数枚の攪拌搬送板を長さ方向に適宜間隔毎に突設しているので、二次乾燥通路内に投入された廃棄パンの粉粒体をこの攪拌搬送板により所定の搬送速度でもって出口側に向かって搬送することができると共に、その間にヒータによって加熱されている二次乾燥通路の加熱壁面やこの二次乾燥通路内の加熱空気によって廃棄パンの粉粒体を、保存添加剤等を添加しなくても飼料として配合するまでの長期保存が可能な低い含水率の粉粒体となるように乾燥処理することができるものである。また、二次乾燥通路内の加熱によって廃棄パンの粉粒体の通路壁面への付着をも防止することができる。  A hollow rotary shaft is also provided in the secondary drying passage in the same manner as the primary drying passage, and the waste pan powder particles are placed on the outer peripheral surface of the hollow rotary shaft toward the outlet side of the secondary drying passage. Since a plurality of agitating and conveying plates to be sent out are provided at appropriate intervals in the length direction, the powder particles of the waste pan put into the secondary drying passage are brought to a predetermined conveying speed by this agitating and conveying plate. It can be transported toward the outlet side, and the powder of the waste pan is stored by the heating wall surface of the secondary drying passage heated by the heater in the meantime or the heated air in the secondary drying passage, preservative additives, etc. Even if it does not add, it can dry-process so that it may become a granular material of the low moisture content which can be preserve | saved for a long time until it mix | blends as a feed. In addition, the heating in the secondary drying passage can also prevent the waste pan powder particles from adhering to the passage wall surface.

以上のように本発明の廃棄パンの処理方法によれば、請求項1に記載したように、廃棄パンを一次乾燥通路内に供給してこの一次乾燥通路内に設けている破砕手段により細かく破砕すると共に破砕されたパンの粉粒体の含水率を低下させた後、二次乾燥通路内に供給して上記破砕されたパンの粉粒体の含水率を更に低下させることを特徴とするものであるから、一次乾燥通路内に供給された廃棄パンを破砕手段によって細かく破砕すると同時にこの一次乾燥通路内で加熱して含水率を低下させることができ、その上、一次乾燥通路から二次乾燥通路内を連続的に搬送通過させながら多量の廃棄パンを短時間で能率よく破砕、乾燥処理を行うことができる。  As described above, according to the disposal method of the waste pan of the present invention, as described in claim 1, the waste pan is supplied into the primary drying passage and finely crushed by the crushing means provided in the primary drying passage. The moisture content of the crushed bread powder is reduced and then supplied to the secondary drying passage to further reduce the moisture content of the crushed bread powder. Therefore, the waste pan supplied in the primary drying passage can be finely crushed by the crushing means and simultaneously heated in the primary drying passage to reduce the water content. In addition, the secondary drying can be performed from the primary drying passage. A large amount of waste bread can be efficiently crushed and dried in a short time while continuously passing through the passage.

さらに、請求項2に係る発明によれば、上記一次乾燥通路の出口から排出されたパンの粉粒体を二次乾燥通路内に連続的に送り込む途上で、さらに二次破砕するので、一次乾燥通路内で粗破砕処理された廃棄パンに混在するパン片や比較的大径の粉粒体を飼料用として配合可能な微細な粉粒体に確実に破砕することができ、粒度の安定化を図ることができるものである。  Furthermore, according to the invention which concerns on Claim 2, since the powdered bread | crumbs discharged | emitted from the exit of the said primary-drying channel | path are continuously sent in the secondary-drying channel | path, further secondary crushing is carried out. Bread pieces mixed with waste bread that has been roughly crushed in the passageway and relatively large-sized powder can be reliably broken into fine powder that can be blended for feed. It can be planned.

The crushing blades 2b are spaced apart in the length direction at three circumferential portions of the hollow rotary shaft 2a, that is, portions having a phase difference of 60 °. Preferably, the crushing blades 2b, 2b adjacent to each other are not provided on the same circumferential surface of the hollow rotary shaft 2a but are shifted on the virtual spiral line. ing.

各破砕羽根2bは図3〜図5に示すように、基端を中空回転軸2aの外周面に一体に固着して該外周面から突設している正面縦長長方形状の支持板2b1と、この支持板2b1の片面に固着しているカッタ板2b2とからなり、このカッタ板2b2の一側端縁部に形成している刃部2b2’を中空回転軸2aの回転方向に向かって支持板2b1の一側端から突出させていると共にこれらの支持板2b1とカッタ板2b2における中空回転軸2aからの突出先端面を上記通路部11の円弧状内面に対して僅かな隙間を存して対向した凸円弧状端面2cに形成して、この凸円弧状端面2cと通路部11の円弧状内面とによって廃棄パンAを擦り潰して細かく粉砕するように構成している。  As shown in FIGS. 3 to 5, each crushing blade 2 b is fixed to the outer peripheral surface of the hollow rotary shaft 2 a integrally with the base end, and has a vertically long rectangular support plate 2 b 1 protruding from the outer peripheral surface; The cutter plate 2b2 is fixed to one surface of the support plate 2b1, and the blade portion 2b2 ′ formed on one edge of the cutter plate 2b2 is moved toward the rotation direction of the hollow rotary shaft 2a. 2b1 is protruded from one side end of the support plate 2b1 and the cutter plate 2b2 so that the protruding tip surfaces from the hollow rotary shaft 2a are opposed to the arcuate inner surface of the passage portion 11 with a slight gap. It is formed on the convex arcuate end surface 2c, and the waste pan A is crushed and finely pulverized by the convex arcuate end surface 2c and the arcuate inner surface of the passage portion 11.

さらに、カッタ板2b2の刃部2b2’は、図5(イ)に示すように、支持板2b1の一側端から全長に亘って一定幅でもって外側方に突出している直状刃に形成されているものと、図5(ロ)に示すように、直状刃の先端部をさらに外方に突設した鎌状の刃部2b2’’に形成してなるものとがあり、この鎌状の刃部2b2’’を有するカッタ板2b2を上記投入ホッパ10の下方から後述する遮蔽板15の近傍部にかけての中空回転軸2aの一端部に突設して、投入ホッパ10から投入された廃棄パンAを引っ掛けて破砕すると共に廃棄パンAがホッパ10の内底部上に滞留するのを防止するようにしている一方、直状刃のみを設けているカッタ板2b2は、遮蔽板15の近傍部から以降の中空回転軸2aに突設した構造としている。  Further, as shown in FIG. 5 (a), the blade portion 2b2 ′ of the cutter plate 2b2 is formed as a straight blade projecting outward with a constant width from one side end of the support plate 2b1. As shown in FIG. 5 (b), there is a sickle-shaped blade portion 2b2 ″ in which the tip of the straight blade is further projected outward. A cutter plate 2b2 having a blade portion 2b2 '' is protruded from one end portion of the hollow rotary shaft 2a from the lower side of the input hopper 10 to the vicinity of a shielding plate 15 to be described later, and discarded from the input hopper 10 While the pan A is hooked and crushed and the waste pan A is prevented from staying on the inner bottom of the hopper 10, the cutter plate 2 b 2 provided with only a straight blade is the vicinity of the shielding plate 15. To the subsequent hollow rotary shaft 2a.

また、上記破砕羽根2bの支持板2b1における一次乾燥通路1の他端部側に向けた面を中空回転軸2aの回転方向に一側端から他側端に向かって緩やかに傾斜させた傾斜面2dに形成してこの傾斜面2dによって廃棄パンAの粉粒体aを一次乾燥通路1の他端側、即ち、排出口9側に送り出すように構成している。この一次乾燥通路1の投入ホッパ10側の端部(閉止板12a側)には、高圧エアーを噴出させて残存した廃棄パンAの粉粒体を排出口9側へ送り出して通路内を清掃する清掃用ブロワを設けておくこともできる。  Further, an inclined surface in which the surface of the support plate 2b1 of the crushing blade 2b facing the other end portion of the primary drying passage 1 is gently inclined from one end to the other end in the rotation direction of the hollow rotary shaft 2a.

To force it to 9 It is. In order to inject hot air having wind pressure from all of these injection nozzles 3a, a certain amount of pressurization is required, and when the pressurization is insufficient with only the hot air supply pipe 8 from one closing plate 12a side. Can also be configured so as to be pressurized from both sides by providing a hot air supply pipe communicating with the inside of the hollow rotary shaft 2a also from the other closing plate 12b side. The ejection port 3b of the ejection nozzle 3a is formed by bending the tip of the ejection nozzle 3a at a substantially right angle toward the feeding direction of the granular material a of the waste pan A.

また、一次乾燥通路1の上記蓋部材13の中央部には図1、図2に示すように廃棄パンAの粉粒体aの加熱によって該粉粒体a内から蒸散する水蒸気を一次乾燥通路1外に熱風の一部と共に排出するための水蒸気排出パイプ14が連結、連通してある。なお、この水蒸気排出パイプ14には排出量を調整するための開閉弁(図示せず)が設けられている。  Further, in the central part of the lid member 13 of the primary drying passage 1, as shown in FIGS. 1 and 2, water vapor evaporated from the inside of the granular material a by heating the granular material a of the waste pan A is supplied to the primary drying passage. A steam discharge pipe 14 for discharging together with a part of the hot air is connected and communicated to the outside. The water vapor discharge pipe 14 is provided with an on-off valve (not shown) for adjusting the discharge amount.

A shielding plate 15 that is primarily closed is disposed, and when the passage is blocked by the shielding plate 15, the inside of the passage portion between the shielding plate 15 and one end closing plate 12 a of the primary drying passage 1 is inserted into the feeding hopper 10. It forms so that it may form in the retention chamber 16 of the waste pan A supplied from.

詳しくは、上記遮蔽板15は図3示すように、その下半部の外周端面15aを一次乾燥通路1の内周面と同一形状に形成していると共に下端部における幅方向の中央部には下端面から一定長さ部分を切除してなる切欠部15bが形成されていて、遮蔽板15を閉止した時にこの切欠部15b内に中空回転軸2aを挿通状態に受け入れて下半部外周端面15aを一次乾燥通路1の内周面に密接させるように形成している。  Specifically, as shown in FIG. 3, the shielding plate 15 has an outer peripheral end surface 15a of the lower half formed in the same shape as the inner peripheral surface of the primary drying passage 1, and at the center in the width direction at the lower end. A notch 15b is formed by cutting out a portion of a certain length from the lower end surface. When the shielding plate 15 is closed, the hollow rotary shaft 2a is inserted into the notch 15b and the lower half outer peripheral end surface 15a is received. Is formed in close contact with the inner peripheral surface of the primary drying passage 1.

この遮蔽板15の上半部は一次乾燥通路1の蓋部材13に設けている通孔17を通じて上方に突出させてあり、その上端部と一次乾燥通路1の蓋部材13上に立設状態で固定しているシリンダ18のピストンロッド18aとを連結部材19によって一体に連結して、該ピストンロッド18aを伸縮させることにより、遮蔽板15を開閉させるようにしている。なお、図3は電動シリンダを用いた遮蔽装置の例を図示したものであるが、エアーシリンダを用いるとさらに小型化も可能であり好ましい。  The upper half of the shielding plate 15 protrudes upward through a through hole 17 provided in the lid member 13 of the primary drying passage 1, and stands on the upper end portion and the lid member 13 of the primary drying passage 1.

The inside of the tertiary drying passage 5 is heated by the hot air supplied into the hollow rotary shaft 54 through the shaft 44 to dry the granular material a of the waste pan A.

さらに、上記二次乾燥通路4と三次乾燥通路5との蓋部材43、53の長さ方向の中央部には、上記一次乾燥通路1と同様に、それぞれの通路内において廃棄パンAの粉粒体aから蒸散する水蒸気を外部に排出するための排出パイプ46、56が連結、連通してあり、これらの熱風排出パイプ46、56に開閉弁(図示せず)を介装している。  Further, in the central portion of the lid members 43 and 53 of the secondary drying passage 4 and the tertiary drying passage 5 in the length direction, as in the case of the primary drying passage 1, powder particles of the waste pan A in each passage. Discharge pipes 46 and 56 for discharging water vapor evaporated from the body a to the outside are connected and communicated with each other, and an open / close valve (not shown) is interposed in the hot air discharge pipes 46 and 56.

二次乾燥通路4の搬送終端部(一端部)と、この搬送終端部の下方に位置する三次乾燥通路5の蓋部材53の一端部間に、二次乾燥通路4内から三次乾燥通路5内に粉粒体aを送り込むための垂直な中間通路7’を連結、連通させていて、この中間通路7’に該中間通路7’内部の水分測定器30を装着していると共に、三次乾燥通路5の搬送終端部(他端部)側の下周部には下方に向けて開口した処理済粉粒体aの排出口9’を設けている。  In the tertiary drying passage 5 from the secondary drying passage 4 between the conveyance end portion (one end portion) of the secondary drying passage 4 and one end portion of the lid member 53 of the tertiary drying passage 5 located below the conveyance termination portion. A vertical intermediate passage 7 ′ for feeding the granular material a is connected and communicated, and a moisture measuring device 30 inside the intermediate passage 7 ′ is attached to the intermediate passage 7 ′, and a tertiary drying passage 5 is provided with a discharge port 9 ′ for the processed granular material a that opens downward.

上記一次乾燥通路1と二次乾燥通路4には、その筒状壁面に全長に亘ってシリコンラバーヒータ等のヒータ(図示せず)を巻き付けて一定の温度に加熱され、通路内を高温にして廃棄パンAを乾燥させるように構成している一方、三次乾燥通路5はその一半部、即ち上記中間通路7’から投入される粉粒体aが他端部に向かって移動する前半部の外周部にのみヒータが巻き付けられていてパンの粉粒体aの水分量が8%以下となるように加熱を行うように構成しているが、他半部の外周部にはヒータが設けられてなく、この三次乾燥通路5の筒状壁面の内底面上を放冷状態で排出口9’に向かってパンの粉粒体aを移動させ、パンの粉粒体aが排出口9’から排出された時に、水分を吸収しないように処理している。  In the primary drying passage 1 and the secondary drying passage 4, a heater (not shown) such as a silicon rubber heater is wound over the entire length of the cylindrical wall surface to be heated to a constant temperature. While the waste pan A is configured to dry, the tertiary drying passage 5 has one half thereof, that is, the outer periphery of the front half in which the granular material a introduced from the intermediate passage 7 'moves toward the other end. The heater is wound only on the part, and it is configured to heat so that the moisture content of the bread granule a is 8% or less, but the outer peripheral part of the other half is provided with a heater. In addition, the bread granule a is moved toward the discharge port 9 ′ in the cooled state on the inner bottom surface of the cylindrical wall surface of the tertiary drying passage 5, and the bread granule a is discharged from the discharge port 9 ′. When it is done, it is treated not to absorb moisture.

また、上記一次〜三次乾燥通路1、4、5内にそれぞれ配設している中空回転軸2a、44、54の回転手段としては、図2に示すように、これらの通路1、4、5の搬送終端側にモータ101、102、103をそれぞれ配設し、これらのモータ101〜103から適宜な減速機構を介して上記中空回転軸2a、44、54をそれぞれ一定の回転速度でもって回転させるようにしている。  Further, as the rotating means of the hollow rotary shafts 2a, 44, 54 disposed in the primary to tertiary drying passages 1, 4, 5, respectively, as shown in FIG. Motors 101, 102, and 103 are disposed on the conveyance end side of the motor, and the hollow rotating shafts 2a, 44, and 54 are rotated from these motors 101 to 103 at a constant rotational speed through an appropriate speed reduction mechanism. I am doing so.

さらに、上記一次〜三次乾燥通路1、4、5の中空回転軸2a、44、54に熱風を供給する熱風供給パイプ8としては、一次乾燥通路1側では、その一端部から突出している中空回転軸2aの一端にロータリージョイントを介して連結、連通しているパイプにヒータH1を設けた熱風供給パイプ8aからなり、二次乾燥通路2側では、その他端部から突出している中空回転軸44にロータリージョイントを介して連結、連通しているパイプにヒータH2を設けた熱風供給パイプ8bからなる。そして、三次乾燥通路5側では、上述したように、二次乾燥通路4内の中空回転軸44の一端部に連結、連通した連通管8cが該三次乾燥通路5内を加熱する熱風供給パイプとなる。  Furthermore, as the hot air supply pipe 8 for supplying hot air to the hollow rotary shafts 2a, 44, 54 of the primary to tertiary drying passages 1, 4, 5, the hollow rotation projecting from one end thereof on the primary drying passage 1 side. It consists of a hot air supply pipe 8a in which a heater H1 is connected to and connected to one end of the shaft 2a via a rotary joint, and on the secondary drying passage 2 side, a hollow rotating shaft 44 protruding from the other end is provided. It consists of a hot air supply pipe 8b in which a heater H2 is provided on a pipe connected and communicated via a rotary joint. On the side of the tertiary drying passage 5, as described above, the communication pipe 8 c connected to and communicated with one end of the hollow rotary shaft 44 in the secondary drying passage 4 is a hot air supply pipe for heating the inside of the tertiary drying passage 5. Become.

これらの熱風供給パイプ8a、8bにはそれぞれ減圧弁V1、V2が介装されてあり、一次乾燥通路2aの中空回転軸2aに連結、連通した熱風供給パイプ8aに設けている減圧弁V1は、二次乾燥通路4側の中空回転軸44に連通した熱風供給パイプ8bに設けている減圧弁V2よりも高い圧力の熱風を通過させることができるように調整している。また、これらの熱風供給パイプ8a、8bは図1に示すように、コンプレッサ(図示せず)からの圧縮空気供給管8’に連結、連通してこの圧縮空気を加熱するように構成している。なお、図1に示した装置では、熱風供給パイプ8によって一次〜三次乾燥通路1、4、5の中空回転軸2a、44、54内へ熱風を供給しているが、一次乾燥通路用と二次、三次乾燥通路用に別々の熱風供給パイプを設けてもよい。  These hot air supply pipes 8a and 8b are respectively provided with pressure reducing valves V1 and V2, and the pressure reducing valves V1 provided in the hot air supply pipe 8a connected to and communicated with the hollow rotary shaft 2a of the primary drying passage 2a are: It adjusts so that the hot air of a pressure higher than the pressure-reduction valve V2 provided in the hot air supply pipe 8b connected to the hollow rotating shaft 44 by the side of the secondary drying channel | path 4 can be passed. Further, as shown in FIG. 1, these hot air supply pipes 8a and 8b are connected to and communicated with a compressed air supply pipe 8 ′ from a compressor (not shown) to heat the compressed air. . In the apparatus shown in FIG. 1, hot air is supplied into the hollow rotary shafts 2a, 44, 54 of the primary to tertiary drying passages 1, 4, 5 by the hot air supply pipe 8, Next, a separate hot air supply pipe may be provided for the tertiary drying passage.

また、一次乾燥通路1内の中空回転軸2aには、該中空回転軸2aの内部に連通した多数本の熱風噴射ノズル3aを突設して中空回転軸2a内に供給された熱風を一次乾燥通路1内に噴射させるように構成しているので、この中空回転軸2aの他端側は閉止しておくか、或いは、絞り弁、開閉弁等によって流量を調整できるように構成しておいてもよいが、上述したように中空回転軸2aの両端側から熱風を該中空回転軸2a内に供給してこの中空回転軸2aに突設している全ての噴射ノズル3aから略均一な圧力でもって熱風を噴射させるようにしておいてもよい。なお、これらの中空回転軸2a、44、54内を流通した熱風は外気に排出してもよいが、再び、上記熱風供給パイプ8側に還流させて再利用するように構成しておくことが望ましい。  The hollow rotary shaft 2a in the primary drying passage 1 is provided with a plurality of hot air jet nozzles 3a communicating with the hollow rotary shaft 2a so that the hot air supplied into the hollow rotary shaft 2a is primarily dried. Since it is configured to be injected into the passage 1, the other end of the hollow rotary shaft 2a is closed, or the flow rate can be adjusted by a throttle valve, an on-off valve, or the like. However, as described above, hot air is supplied from both ends of the hollow rotary shaft 2a into the hollow rotary shaft 2a, and is supplied from all the injection nozzles 3a protruding from the hollow rotary shaft 2a with a substantially uniform pressure. Thus, hot air may be jetted. The hot air flowing through these hollow rotary shafts 2a, 44, 54 may be discharged to the outside air, but may be configured to be recirculated to the hot air supply pipe 8 and reused. desirable.

このように構成した廃棄パンAの処理装置によって廃棄パンを飼料の一部として配合させるに最適な径と低い含水率の粉粒体aに処理するには、まず、一次乾燥通路1と二次乾燥通路4及び三次乾燥通路5の内部に配設している中空回転軸2a、44、54を一定の回転速度でもって回転させると共に、これらの一次〜三次乾燥通路2a、44、54をその筒状壁面の外周面に設けているヒータによって加熱し、且つ熱風供給パイプ8(8a、8b)を通じて中空回転軸2a、44、54内に熱風を流通させることによって内部からも加熱する。  In order to process the powder pan a having the optimum diameter and low water content for mixing the waste pan as part of the feed by the processing device for the waste pan A configured as described above, first, the primary drying passage 1 and the secondary drying passage 1 The hollow rotary shafts 2a, 44, and 54 disposed inside the drying passage 4 and the tertiary drying passage 5 are rotated at a constant rotational speed, and the primary to tertiary drying passages 2a, 44, and 54 are arranged in their cylinders. It heats by the heater provided in the outer peripheral surface of the shape wall surface, and also heats from the inside by circulating hot air in the hollow rotary shafts 2a, 44, 54 through the hot air supply pipes 8 (8a, 8b).

この状態にして投入ホッパ10内に廃棄パンAを連続的に投入し、この投入ホッパ10を通じて一次乾燥通路1の一端部内に供給する。この際、一次乾燥通路1の一端部側に設けている遮蔽板15をシリンダ18の作動によって降下させてその切欠部15bを中空回転軸2aにおける破砕羽根2bや熱風噴射ノズル3aが設けられていない部分に跨がらせるように挿入し、遮蔽板15の下半部外周端面15aを一次乾燥通路1の内周面に密接させることによって、この遮蔽板15と一次乾燥通路の一端側閉止板12aとの間の通路部内を一次乾燥通路1の排出口9側の通路に対して遮断された滞留室16に形成する。  In this state, the waste pan A is continuously charged into the charging hopper 10 and supplied into one end of the primary drying passage 1 through the charging hopper 10. At this time, the shielding plate 15 provided on one end side of the primary drying passage 1 is lowered by the operation of the cylinder 18, and the cutout portion 15b is not provided with the crushing blade 2b or the hot air injection nozzle 3a in the hollow rotary shaft 2a. By inserting the lower half outer peripheral end surface 15a of the shielding plate 15 into close contact with the inner peripheral surface of the primary drying passage 1, the shielding plate 15 and one end side closing plate 12a of the primary drying passage Is formed in a staying chamber 16 that is blocked from the passage on the discharge port 9 side of the primary drying passage 1.

従って、投入ホッパ10から投入された多量の廃棄パンAは一次乾燥通路1内を排出口9側に移動することなくこの滞留室16内に充満した状態となり、中空回転軸2aの外周面に突設している破砕羽根2bの回転により攪拌され且つパン同士が擦り合って押しつぶされると共に、この破砕羽根2bの凸円弧状端面2cと通路部11の円弧状内面との隙間に食い込む廃棄パンAは擦り潰すようにして細かく破砕される。  Therefore, a large amount of the waste pan A fed from the feeding hopper 10 does not move to the discharge port 9 side in the primary drying passage 1 but fills the staying chamber 16 and projects into the outer peripheral surface of the hollow rotary shaft 2a. The waste pan A that is agitated by the rotation of the crushing blade 2b and is crushed and crushed, and the waste pan A that bites into the gap between the convex arc-shaped end surface 2c of the crushing blade 2b and the arc-shaped inner surface of the passage portion 11 is It is crushed finely by crushing.

さらに、滞留室16内の破砕羽根2bのカッタ板2B2は、直状刃の先端部を外方に突設してなる鎌状の刃部2b2’’に形成しているので、投入ホッパ10から投入された廃棄パンAをこの鎌状の刃部2b2’’で引っ掛けながら破砕すると共に廃棄パンAがホッパ10の内底部上に滞留するのを防止する。また、滞留室16内に密に充満している廃棄パンAは、破砕羽根2bの回転に対して抵抗し、従って、大形の廃棄パンAなどは破砕羽根2bの回転力によって分断、破砕される。  Further, the cutter plate 2B2 of the crushing blade 2b in the staying chamber 16 is formed into a sickle-shaped blade portion 2b2 ″ formed by projecting the tip portion of the straight blade outward. The thrown-out waste pan A is crushed while being hooked by the sickle-shaped blade portion 2b2 ″, and the waste pan A is prevented from staying on the inner bottom portion of the hopper 10. Further, the waste pan A that is densely filled in the staying chamber 16 resists the rotation of the crushing blade 2b. Therefore, the large waste pan A and the like are divided and crushed by the rotational force of the crushing blade 2b. The

また、熱風供給パイプ8を通じて中空回転軸2a内に供給されている熱風は、噴射ノズル3aから上記滞留室16を含む一次乾燥通路1内に流出し、ヒータによる加熱と共に一次乾燥通路1内の空気が乾燥した高温空気に変化している。従って、滞留室16内においては、廃棄パンAの内部に含まれている水分の一部が滞留室16内に蒸散し、含水率が低下させられる。  Moreover, the hot air supplied into the hollow rotary shaft 2a through the hot air supply pipe 8 flows out from the injection nozzle 3a into the primary drying passage 1 including the staying chamber 16, and is heated by the heater and air in the primary drying passage 1 Has changed to dry hot air. Therefore, in the staying chamber 16, a part of the water contained in the waste pan A is evaporated in the staying chamber 16, and the moisture content is lowered.

廃棄パンAは通常、35〜40%の含水率を有しており、このままでは含水率が高くで飼料として使用するまでに腐敗してしまうので、添加剤等を使用することなくそのまま飼料に配合するまでの保存を可能にするには8%以下の含水率にする必要がある。また、廃棄パンAの破砕片や粉粒体aが大形であったり、その大きさや粒径にバラツキがあると、他の飼料配合物との配合割合等を正確に設定することが困難となるので、全ての廃棄パンAを5mm以下の細かい粒径にまで粉砕する必要がある。  Waste bread A usually has a moisture content of 35-40%, and if it is left as it is, the moisture content is high and it will rot before use as feed, so it is blended directly into the feed without using any additives. It is necessary to make the water content 8% or less in order to enable the storage until it is done. In addition, if the crushed pieces and the powders a of the waste bread A are large, or if the size or particle size varies, it is difficult to accurately set the blending ratio with other feed blends. Therefore, it is necessary to grind all the waste pans A to a fine particle size of 5 mm or less.

このような条件を満たす廃棄パンAの粉粒体aは、上記滞留室16内での破砕羽根2bによる攪拌、破砕処理や噴射ノズル3aからの熱風供給による加熱処理だけでは、例え、長時間かけても得ることが困難である。従って、滞留室16内で廃棄パンAを比較的小さなパン片と大小径の粉粒体aとが混在した状態となるまで一次破砕処理を行ったのち、遮蔽板15を開放する。なお、遮蔽板15は大きく引き上げることなく、滞留室16の内底面から3cm位まで上昇させ、ある程度まで粉砕されたパン片をその空隙部から滞留室16外に通過させてもよい。  The granular material a of the waste pan A that satisfies such conditions can be applied for a long time only by stirring, crushing processing by the crushing blade 2b in the staying chamber 16 and heating processing by supplying hot air from the spray nozzle 3a. It is difficult to obtain. Therefore, after the waste crush A is subjected to the primary crushing process until the waste bread A is mixed with the relatively small bread pieces and the large and small powder particles a in the staying chamber 16, the shielding plate 15 is opened. The shielding plate 15 may be lifted up to about 3 cm from the inner bottom surface of the retention chamber 16 without pulling up greatly, and the bread pieces crushed to a certain extent may be passed outside the retention chamber 16 from the gap.

遮蔽板15が開放されると、上記破砕処理されたパン片と粉粒体aは、中空回転軸2aの外周面に突設している上記破砕羽根2bの傾斜面2dと、粉粒体送り出し方向に向けている噴射ノズル3aの噴出口3bから噴出する熱風とによって一次乾燥通路1の排出口9側に向かって搬送される。この搬送途上において、ヒータによって加熱されている一次乾燥通路1の周壁面との接触や該一次乾燥通路1内の高温空気によりパン片や粉粒体a内に含まれている水分が一次乾燥通路1内に水蒸気となって排出され、水蒸気排出パイプ14を通じて一部の高温空気(熱風)と共に一次乾燥通路外に排出される。  When the shielding plate 15 is opened, the crushed bread pieces and the granular material a are sent to the inclined surface 2d of the crushed blade 2b protruding from the outer peripheral surface of the hollow rotating shaft 2a, and the granular material is sent out. It is conveyed toward the discharge port 9 side of the primary drying passage 1 by hot air jetted from the jet outlet 3b of the jet nozzle 3a directed in the direction. In the course of this conveyance, the moisture contained in the bread pieces and the granular material a by the contact with the peripheral wall surface of the primary drying passage 1 heated by the heater and the high temperature air in the primary drying passage 1 is removed from the primary drying passage. 1 is discharged as water vapor, and is discharged out of the primary drying passage together with some high-temperature air (hot air) through the water vapor discharge pipe 14.

一次乾燥通路1内でのパン片や粉粒体aの排出口9側への搬送は、上記破砕羽根2bの傾斜面2dによる搬送作用や噴射ノズル3aから常時流出している低速の熱風だけでは不充分であり、円滑に行うことができない。そのため、一定時間毎、例えば10秒間毎に熱風供給パイプ8を通じて高圧加熱空気(熱風)を中空回転軸2a内に圧送し、排出口9側に向けている噴射ノズル3aの噴出口3bから瞬間的に噴発させてこの高速熱風流によりパン片や粉粒体aを排出口9側に向かって吹き飛ばすことにより、搬送速度を調整している。  In the primary drying passage 1, the bread pieces and the powder a are transported to the discharge port 9 side only by the transport action by the inclined surface 2d of the crushing blade 2b and the low-speed hot air always flowing out from the spray nozzle 3a. Insufficient and cannot be carried out smoothly. Therefore, high-pressure heated air (hot air) is pumped into the hollow rotary shaft 2a through the hot air supply pipe 8 every fixed time, for example, every 10 seconds, and instantaneously from the outlet 3b of the injection nozzle 3a directed to the outlet 9 side. The conveying speed is adjusted by blowing off the bread pieces and the granular material a toward the discharge port 9 by the high-speed hot air flow.

さらに、パン片や粉粒体aは多孔質であるから、噴射ノズル3aの噴出口3bから噴出するこの熱風が、これらのパン片や粉粒体内の微細な空隙を流通して内部からも加熱し、含まれている水分の除去作用が一層効果的に行われる。また、回転する破砕羽根2bの凸円弧状端面2cと一次乾燥通路1の通路部11の円弧状内面とによって、これらの面間に食い込む廃棄パンAを擦り潰すようにして細かく破砕する。  Furthermore, since the bread pieces and the granular material a are porous, this hot air discharged from the outlet 3b of the injection nozzle 3a circulates through the fine voids in the bread pieces and the granular material and is also heated from the inside. In addition, the action of removing contained moisture is more effectively performed. Further, the waste pan A that bites between these surfaces is crushed finely by the convex arcuate end surface 2c of the rotating crushing blade 2b and the arcuate inner surface of the passage portion 11 of the primary drying passage 1.

こうして、適度に乾燥及び破砕処理されたパン片や粉粒体aは、一次乾燥通路1の他端に達すると排出口9を通じて垂直通路7内に落下する。この垂直通路7内には有底筒状の網状体7aが配設されていると共に、該網状体7aの内底面上に回転軸21から放射状に突出している複数枚の回転刃20が設けられている。従って、網状体7a上に落下したパン片や粉粒体aにおいて、網状体7aの網目からなる多数の小孔7bよりも小径の微細な粉粒体aはそのまま網状体7aの底面や周壁面の小孔7bを通過して二次乾燥通路4の受入口45側に落下する一方、小孔7bよりも大径のパン片や粉粒体aは高速回転する回転刃20によって細かく分断される。  Thus, the bread pieces and the granular material a that have been appropriately dried and crushed fall into the vertical passage 7 through the discharge port 9 when reaching the other end of the primary drying passage 1. In the vertical passage 7, a bottomed cylindrical mesh body 7a is disposed, and a plurality of rotary blades 20 projecting radially from the rotary shaft 21 are provided on the inner bottom surface of the mesh body 7a. ing. Therefore, in the bread pieces and the granular material a that have fallen on the mesh body 7a, the fine powder particles a having a smaller diameter than the large number of small holes 7b made of the mesh of the mesh body 7a remain as they are. While passing through the small hole 7b and falling to the receiving port 45 side of the secondary drying passage 4, the bread pieces and the granular material a larger in diameter than the small hole 7b are finely divided by the rotary blade 20 that rotates at high speed. .

この際、回転軸21から突設している一枚の掻き上げ板22は、その回転方向側の下傾端縁が網状体7aの内底面に接するようにして回転して、網状体7aの小孔7bを通過できないパン片や粗い粉粒体aを掻き上げて目詰まりが生じないようにすると共に掻き上げられたパン片や粗い粉粒体aを高速回転する回転刃20の切断刃先縁20aによって細かく分断し、この分断作用を網状体7aの小孔7bに通過可能な小径の粉粒体aとなるまで繰り返し行って網状体7a内に落下する全ての廃棄パンAのパン片や粉粒体aを微細な粒子状粉粒体aに粉砕処理する。なお、網状体7aを通過する廃棄パンAのパン片や粉粒体aの単位時間当たりの処理量と、上記投入ホッパ10に投入する廃棄パンAの投入量とを略等しくして、一次乾燥通路1内から二次乾燥通路4、三次乾燥通路5内を粉粒体aが連続的に搬送されながら処理するように構成している。  At this time, the one scraping plate 22 protruding from the rotating shaft 21 rotates so that the downwardly inclined edge of the rotating direction side is in contact with the inner bottom surface of the mesh body 7a. The cutting edge of the rotary blade 20 that rakes up the bread pieces and coarse particles a that cannot pass through the small holes 7b to prevent clogging and rotates the bread pieces and coarse particles a that have been scraped up at a high speed. 20a, and this cutting action is repeated until it becomes a small-diameter granular material a that can pass through the small holes 7b of the mesh body 7a, and all pieces of bread and powder of waste bread A that fall into the mesh body 7a The granule a is pulverized into fine particulate powder a. It should be noted that the processing amount per unit time of the waste pieces A and the granular material a passing through the mesh body 7a and the input amount of the waste pan A to be input into the input hopper 10 are made substantially equal to each other and primary drying is performed. It is configured so that the granular material a is processed while being continuously conveyed from the passage 1 to the secondary drying passage 4 and the tertiary drying passage 5.

こうして、粉砕処理された微細な粒子状の小径粉粒体aは受入口45を通じて二次乾燥通路4の他端部内に排出されると、この二次乾燥通路4内には、長さ方向に適宜間隔毎に攪拌搬送手段6を構成している攪拌搬送板61を備えた中空回転軸44が配設されてあり、これらの攪拌搬送板61の先端面65を二次乾燥通路4の壁面の内周面に摺接又は近接させているので、該攪拌搬送板61の回転によって粉粒体aが二次乾燥通路4の周方向に攪拌されてヒータにより加熱されている二次乾燥通路4の壁面に均一に接触し、内部に含んでいる水分がさらに蒸散、除去されて含水率が低下する。  Thus, when the pulverized fine particulate small-diameter granular material a is discharged into the other end of the secondary drying passage 4 through the receiving port 45, the secondary drying passage 4 has a lengthwise direction. A hollow rotary shaft 44 provided with a stirring and conveying plate 61 that constitutes the stirring and conveying means 6 is disposed at appropriate intervals, and the tip surface 65 of these agitating and conveying plates 61 is connected to the wall surface of the secondary drying passage 4. Since the inner peripheral surface is in sliding contact with or close to the inner peripheral surface, the powder a is stirred in the circumferential direction of the secondary drying passage 4 by the rotation of the stirring and conveying plate 61 and heated by the heater. Evenly contacting the wall surface, the moisture contained inside is further evaporated and removed, and the moisture content decreases.

さらに、中空回転軸44内には熱風供給パイプ8bを通じて熱風が流通してあり、この熱風によって中空回転軸44、攪拌搬送板61が加熱されていると共に二次乾燥通路4内の空気も加熱されているので、粉粒体a内の水分の除去作用が一層促進される。その上、攪拌搬送板61は、中空回転軸44の長さ方向に長い横長長方形状に形成されていると共に粉粒体搬送面を中空回転軸44の回転方向に一端部側から他端部側に向かって緩やかに傾斜させた搬送傾斜面64に形成しているので、攪拌搬送板61の回転に従ってその搬送傾斜面64により二次乾燥通路4の出口側に搬送される粉粒体aの搬送速度が遅く、従って、二次乾燥通路4内での乾燥処理時間が長くなって粉粒体aが効果的に乾燥処理される。  Further, hot air is circulated through the hot air supply pipe 8b in the hollow rotary shaft 44. The hot rotary air heats the hollow rotary shaft 44 and the stirring and conveying plate 61 and also heats the air in the secondary drying passage 4. Therefore, the action of removing moisture in the granular material a is further promoted. In addition, the stirring and conveying plate 61 is formed in a horizontally long rectangular shape that is long in the length direction of the hollow rotary shaft 44, and the granular material conveying surface is moved from one end side to the other end side in the rotational direction of the hollow rotary shaft 44. Is formed on the conveyance inclined surface 64 which is gently inclined toward the surface, so that the granular material a conveyed by the conveyance inclined surface 64 to the outlet side of the secondary drying passage 4 according to the rotation of the agitation conveyance plate 61 is conveyed. The speed is low, and therefore, the drying process time in the secondary drying passage 4 is increased, and the granular material a is effectively dried.

このように粉粒体aが二次乾燥通路4内で乾燥されながら搬送されて該二次乾燥通路4の搬送終端部に達すると、垂直な中間通路7’内を通じて二次乾燥通路4の下方に配設している三次乾燥通路5の一端部内に落下する。この際、上記中間通路7’の装着している水分測定器30によって粉粒体aの水分量(中間通路7’内の水分量)を検出し、その水分量が8%以下となるように、三次乾燥通路5の前半部内の加熱の程度をそのヒータH2によって調整、制御するか、或いは、中空回転軸54の回転速度を変化させて粉粒体aの三次乾燥通路5内における滞留時間を調整して乾燥の度合いを制御する。  In this way, when the granular material a is conveyed while being dried in the secondary drying passage 4 and reaches the conveying terminal end of the secondary drying passage 4, the lower portion of the secondary drying passage 4 passes through the vertical intermediate passage 7 ′. It falls into one end part of the tertiary drying passage 5 arranged in the. At this time, the moisture measuring device 30 attached to the intermediate passage 7 ′ detects the moisture content of the granular material a (the moisture content in the intermediate passage 7 ′) so that the moisture content is 8% or less. The degree of heating in the first half of the tertiary drying passage 5 is adjusted and controlled by the heater H2, or the rotation speed of the hollow rotating shaft 54 is changed to change the residence time of the granular material a in the tertiary drying passage 5. Adjust to control the degree of drying.

そして、この三次乾燥通路5の前半部内を微細な粉粒体aが中空回転軸54に突設している攪拌搬送板61aによって攪拌されながら搬送傾斜面64aによってゆっくりと排出口9’に向かって搬送される間に、全ての粉粒体aを保存が可能な含水率8%以下の低含水率にまで乾燥処理したのち、ヒータH2が設けられていない後半部を通過中に熱がさまされて排出口9’から適宜な収納容器B等に投入、収納する。この三次乾燥通路5の後半部内でパンの粉粒体aの熱をさますのは、熱いまま三次乾燥通路5から取り出すと、水分を吸収して固まってしまうからである。なお、粉粒体aに含まれる水分は加熱によって水蒸気となって二次乾燥通路4内や三次乾燥通路5内に蒸散し、排出パイプ46、56を通じて外部に排出される。上記排出口9’には、一次乾燥通路1側の上記ホッパ10と同様に、ゲートシャッターを設けて不使用時におけるネズミ等の小動物や虫等の侵入を阻止しておくこともできる。  And in the front half part of this tertiary drying channel | path 5, while the fine granular material a is stirred by the stirring conveyance board 61a protrudingly provided in the hollow rotating shaft 54, it slowly goes to discharge port 9 'by the conveyance inclined surface 64a. While being transported, after drying all the granules a to a low moisture content of 8% or less, which can be stored, the heat is dissipated while passing through the latter half where the heater H2 is not provided. Then, it is charged and stored in an appropriate storage container B or the like from the discharge port 9 ′. The reason why the bread granule a is heated in the latter half of the tertiary drying passage 5 is that when it is taken out from the tertiary drying passage 5 while being hot, it absorbs moisture and solidifies. The moisture contained in the granular material a is converted into water vapor by heating, evaporates in the secondary drying passage 4 and the tertiary drying passage 5, and is discharged to the outside through the discharge pipes 46 and 56. Similarly to the hopper 10 on the primary drying passage 1 side, the discharge port 9 ′ may be provided with a gate shutter to prevent entry of small animals such as mice and insects when not in use.

本発明に係る廃棄パンの処理方法及び処理装置は、コンビニエンスストアや食品製造工場などから排出される廃棄パンを効率良く粉砕、乾燥させて、家畜用飼料等に混合するなどして用いることができるようにパンを粉体状に加工処理することができる。  The waste bread processing method and processing apparatus according to the present invention can be used by efficiently crushing and drying waste bread discharged from a convenience store, a food manufacturing factory, etc., and mixing it with livestock feed or the like. Thus, the bread can be processed into powder.
