Description

本発明は破砕機構を備える乾燥機を含む乾燥装置に関し、特に水分を含む有機性残渣を落下させながら乾燥させる乾燥機を含む乾燥装置に関する。   The present invention relates to a drying apparatus including a dryer having a crushing mechanism, and more particularly to a drying apparatus including a dryer that dries while dropping an organic residue containing moisture.
従来、食品や飼料、または各種工場から排出される有機性残渣等を乾燥させる乾燥機として筒型の乾燥機本体と、熱供給手段と、を備える乾燥機が知られている。例えば特許文献1には、乾燥機下方に向かって直径が小さくなる逆円錐型の乾燥機本体と、この乾燥機の内部を加熱する熱供給手段とを備える乾燥機が開示されている。   2. Description of the Related Art Conventionally, a dryer having a cylindrical dryer body and a heat supply means is known as a dryer for drying food and feed, or organic residues discharged from various factories. For example, Patent Document 1 discloses a dryer including an inverted conical dryer body whose diameter decreases toward the bottom of the dryer, and heat supply means for heating the inside of the dryer.
特許文献1に開示された乾燥機は、乾燥機本体内部に設けられた処理槽がジャケットに覆われ、処理槽とジャケットとの間に熱風等の加熱媒体が熱供給手段から供給されることで処理槽内が加熱され被処理物を乾燥させる間接加熱方式の乾燥機である。この乾燥機の処理槽内には、垂直方向に延びる回転軸と、この回転軸に固定された回転翼とが設けられている。   In the dryer disclosed in Patent Document 1, the treatment tank provided inside the dryer body is covered with a jacket, and a heating medium such as hot air is supplied from the heat supply means between the treatment tank and the jacket. This is an indirect heating type dryer that heats the inside of the treatment tank and dries the object to be treated. A rotating shaft extending in the vertical direction and a rotating blade fixed to the rotating shaft are provided in the treatment tank of the dryer.
上記乾燥機では、被処理物は乾燥機上部側から処理槽内に供給され、当該処理槽内を垂直方向に落下する間に加熱され、乾燥される。被処理物は乾燥機内部を落下する間に処理槽内部に設けられた回転翼により破砕されて砕片化するため、塊状で乾燥処理に供される被処理物であっても効率よく乾燥させることができる。   In the dryer, the object to be processed is supplied into the treatment tank from the upper side of the dryer, and is heated and dried while dropping in the treatment tank in the vertical direction. Since the material to be treated is crushed and broken into pieces by the rotary blades provided inside the treatment tank while falling inside the dryer, it is possible to efficiently dry even the material to be treated that is subjected to a drying process in a lump. Can do.
また、特許文献2には家庭から排出される生ゴミを含む一般廃棄物を乾燥させる装置として、略円筒状の乾燥機本体に熱風供給手段が接続された乾燥機と、前記乾燥機後段に設けられたサイクロンとを含む乾燥装置が開示されている。この乾燥装置の乾燥機内部には、回転軸に固定された打撃破砕鎖が設けられ、乾燥機の上部から投入された一般廃棄物が落下しながら打撃破砕されるとともに、熱風供給手段から供給される熱風により乾燥される。

しかし、特許文献1の乾燥機は間接加熱方式であり熱効率が悪い。また、加熱媒体がすり鉢状になった乾燥機本体の下部から供給されるため、被処理物が処理槽下部側で外壁に接して高温にさらされる。このため、被処理物が熱により容易に変性する物質を含む場合、被処理物の性状を変化させてしまう場合がある。さらに、被処理物が茶滓やおから等のように粒径が比較的小さく均一で付着性があるような場合、被処理物を破砕するために設けられた回転翼に被処理物が付着し、付着物の剥離に手間がかかる問題もある。   However, the dryer of patent document 1 is an indirect heating system, and its thermal efficiency is bad. Moreover, since a heating medium is supplied from the lower part of the dryer main body made into the shape of a mortar, the to-be-processed object is exposed to high temperature in contact with an outer wall at the process tank lower part side. For this reason, when a to-be-processed object contains the substance which denatures easily with a heat | fever, the property of a to-be-processed object may be changed. Furthermore, when the object to be processed is relatively small in particle size, such as teacup or okara, the object to be processed adheres to the rotor blades provided to crush the object to be processed. However, there is also a problem that it takes time to peel off the deposits.
一方、特許文献2の乾燥装置は一般廃棄物をゴミ袋に入った状態で投入して破砕乾燥させるものであり、打撃鎖により破砕された被処理物は略円筒状の乾燥機本体下部から吹き込まれる熱風により乾燥されるが、乾燥室内部での熱風の挙動がコントロールされていない。このため、被処理物が熱風と効率よく接触せずに乾燥が充分でなく、廃棄物を減量化することはできても、食品等として利用される物質を高い品質で乾燥させることは困難であった。   On the other hand, the drying device of Patent Document 2 is for throwing out general waste in a garbage bag and crushing and drying, and the object crushed by the striking chain is blown from the lower part of the substantially cylindrical dryer body. However, the behavior of hot air inside the drying chamber is not controlled. For this reason, it is difficult to dry a substance used as food or the like with high quality even though the object to be treated is not efficiently contacted with hot air and drying is not sufficient and waste can be reduced. there were.
本発明は上記課題を鑑みてなされ、被処理物の熱変性を防止して、被処理物を迅速かつ充分に乾燥させることができる乾燥機を備える乾燥装置を提供することを目的とする。   This invention is made | formed in view of the said subject, and it aims at providing the drying apparatus provided with the dryer which prevents the thermal denaturation of a to-be-processed object and can dry a to-be-processed object quickly and fully.
本発明は逆円錐型の乾燥室を備える乾燥機であって、乾燥室の内部を旋回して上昇する熱風を生じさせる熱風旋回手段と、好ましくはこの熱風と逆方向に回転する回転軸に固定したチェーンを備える乾燥機を含む乾燥装置を提供する。より具体的には本発明は以下を提供する。   The present invention is a dryer having an inverted conical drying chamber, which is fixed to a hot air swirling means for generating hot air that swirls and rises inside the drying chamber, and preferably a rotating shaft that rotates in a direction opposite to the hot air. A drying apparatus is provided that includes a dryer having a chain. More specifically, the present invention provides the following.
(1) 略円筒状で一端面を天井とし他端面を底とする乾燥室が内部に形成された乾燥機本体と、前記乾燥機本体の乾燥室に供給される熱風を発生させる熱風発生手段と、を備える乾燥機を含む乾燥装置であって、前記乾燥機は、前記乾燥室の内部において前記熱風を旋回させながら上昇させる熱風旋回手段をさらに備え、前記乾燥機本体は、前記乾燥室内部に設けられ底側から天井側に延びる回転軸と、一端が当該回転軸に固定されたチェーンと、前記回転軸を回転させる回転手段と、を備えることを特徴とする乾燥装置。   (1) A dryer body in which a drying chamber having a substantially cylindrical shape with one end face as a ceiling and the other end face as a bottom is formed, and hot air generating means for generating hot air supplied to the drying chamber of the dryer body. The dryer further includes hot air swirling means for raising the hot air while swirling the interior of the drying chamber, and the dryer body is disposed inside the drying chamber. A drying apparatus comprising: a rotary shaft that is provided and extends from the bottom side to the ceiling side; a chain having one end fixed to the rotary shaft; and a rotating means that rotates the rotary shaft.
本発明に係る乾燥機は、乾燥機本体内部に設けられた空間を乾燥室として、この乾燥室に熱風を吹き込むことにより乾燥室内を乾燥用雰囲気として乾燥処理を行う熱風乾燥式の乾燥機である。乾燥機本体の外形は特に限定されず、例えば円筒状容器の外側を任意の形状の保温材で覆ってもよい。   The dryer according to the present invention is a hot air drying type dryer in which a space provided in the inside of the dryer body is used as a drying chamber, and a drying process is performed with the drying chamber as a drying atmosphere by blowing hot air into the drying chamber. . The outer shape of the dryer main body is not particularly limited, and for example, the outside of the cylindrical container may be covered with a heat insulating material having an arbitrary shape.
乾燥室の形状は、乾燥機本体の設置面(地面)に対して垂直方向に長い略円形筒状であり、本明細書において「円筒形」には水平断面が略円状のものが含まれ、片側端縁が先端に向かって細くなる形状が含まれるものとする。円筒の片側端縁が先端に向かって細くなる形状としては、例えば略円錐形が挙げられる。   The shape of the drying chamber is a substantially circular cylindrical shape that is long in the direction perpendicular to the installation surface (ground) of the dryer body. In addition, a shape in which one side edge is narrowed toward the tip is included. Examples of the shape in which the one side edge of the cylinder becomes narrower toward the tip include a substantially conical shape.
乾燥機は乾燥室の互いに対向する端面の一方を天井、他方を底として設置され、乾燥室の天井側に設けられた供給口から供給された被処理物を乾燥室内で落下させながら熱風乾燥させる。供給口は乾燥室を構成する円筒の側壁の天井に近い側に設けてもよく、天井となる円筒端面に設けてもよい。一方、熱風口は乾燥室内を旋回して上昇する熱風(以下、「熱気流サイクロン」)を発生させやすくするため、円筒側壁の底部側に設けることが好ましい。   The dryer is installed with one of the opposite end faces of the drying chamber as the ceiling and the other as the bottom, and the processing object supplied from the supply port provided on the ceiling side of the drying chamber is dried with hot air while dropping in the drying chamber. . The supply port may be provided on the side close to the ceiling of the cylindrical side wall constituting the drying chamber, or may be provided on a cylindrical end surface serving as the ceiling. On the other hand, the hot air vent is preferably provided on the bottom side of the cylindrical side wall in order to easily generate hot air that swirls and rises in the drying chamber (hereinafter referred to as “hot air cyclone”).
乾燥室内の略中心には地面に対して略垂直な回転軸を設け、この回転軸にチェーンの一端を固定する。チェーンは回転軸の長さ方向の異なる位置に多段に設けることが好ましい。また、回転軸の長さ方向の同一位置において複数のチェーンを設けてもよく、この場合複数のチェーンは等間隔で固定することが好ましい。すなわち例えば同一位置に2本のチェーンを固定する場合は回転軸を挟んで対向する位置に設け、同一位置に3本のチェーンを設ける場合は120°間隔で設けることが好ましい。また、チェーンは回転軸から乾燥室の側壁までの長さより2〜15mm程度、特に5〜10mm程度短くし、回転軸の長手方向に沿って多段に設ける場合は5〜50cm間隔とすることが好ましい。   A rotation shaft substantially perpendicular to the ground is provided at the approximate center in the drying chamber, and one end of the chain is fixed to this rotation shaft. The chain is preferably provided in multiple stages at different positions in the length direction of the rotating shaft. Further, a plurality of chains may be provided at the same position in the length direction of the rotating shaft, and in this case, the plurality of chains are preferably fixed at equal intervals. That is, for example, when two chains are fixed at the same position, they are preferably provided at positions facing each other with the rotating shaft in between, and when three chains are provided at the same position, it is preferably provided at 120 ° intervals. In addition, the chain is preferably about 2 to 15 mm shorter than the length from the rotating shaft to the side wall of the drying chamber, particularly about 5 to 10 mm, and is preferably 5 to 50 cm when provided in multiple stages along the longitudinal direction of the rotating shaft. .
回転軸には、熱気流サイクロンの旋回方向と同方向、逆方向、または正逆切替可能にこの回転軸を回転させる回転手段を接続する。回転手段は特に、熱気流サイクロンの旋回方向と逆方向に回転軸を回転させるものであることが好ましく、例えばモータ等の駆動手段で構成できる。   The rotating shaft is connected to rotating means for rotating the rotating shaft so as to be switchable in the same direction, the reverse direction, or the forward / reverse direction with respect to the turning direction of the hot air current cyclone. In particular, the rotating means preferably rotates the rotating shaft in the direction opposite to the turning direction of the hot air cyclone, and can be constituted by a driving means such as a motor.
熱風旋回手段としては、乾燥室底部側の外周円の接線方向に延びるように接続された熱風供給管が挙げられる。   As the hot air swirl means, there is a hot air supply pipe connected so as to extend in the tangential direction of the outer peripheral circle on the drying chamber bottom side.
本発明によれば、乾燥機上部から供給される被処理物を、回転するチェーンで打撃破砕することにより砕片化するとともに、乾燥室の壁面に沿って旋回して乾燥室内部を上昇する熱気流サイクロンと接触させる。本発明では、熱風を乾燥室内部で旋回させているため、被処理物がチェーンにより砕片化されやすく、また、熱風との接触効率も高い。したがって本発明によれば、被処理物を短時間で効率よく乾燥させることができる。   According to the present invention, the hot air stream which is broken up by hitting and crushing the workpiece supplied from the upper part of the dryer with a rotating chain and swirling along the wall surface of the drying chamber and rising inside the drying chamber. Contact with cyclone. In the present invention, since the hot air is swirled in the drying chamber, the object to be processed is easily broken into pieces by the chain, and the contact efficiency with the hot air is high. Therefore, according to this invention, a to-be-processed object can be dried efficiently in a short time.
チェーンは板状の回転翼に比して回転させやすく、高速回転が可能であるため、被処理物を短時間で砕片化できる。また、回転軸の回転を停止させればチェーンは回転軸に沿って垂下するため、回転軸に洗浄液を流しかけることで回転軸とともに洗浄できるため、回転翼を設ける場合のように複数の回転翼をそれぞれ洗浄する手間が不要となる。   Since the chain is easier to rotate than a plate-like rotary blade and can be rotated at a high speed, the workpiece can be broken into pieces in a short time. Also, if the rotation of the rotating shaft is stopped, the chain hangs along the rotating shaft, so that it can be cleaned together with the rotating shaft by pouring a cleaning liquid on the rotating shaft. The need to wash each of them becomes unnecessary.
さらに本発明では、被処理物は乾燥機上部から供給されて乾燥室内で砕片化されて落下するため、水分を含んだ状態で砕片化された被処理物は乾燥室下部から供給された高温の熱風と接触して短時間で乾燥されるとともに、熱風の温度を低下させる。一方、乾燥されて比重が低下した被処理物は熱気流サイクロンにより乾燥室上部に吹き上げられ、乾燥室上部で2〜30分程度、滞留する間により確実に乾燥される。ここで、乾燥室上部側の熱風は温度が低下しているため、被処理物が高温の熱風に長時間さらされて熱変性することが防止される。したがって、本発明は、被処理物として再利用に供される茶滓、おから、および焼酎の絞り滓といった有機性残渣の乾燥に特に好適に使用できる。   Furthermore, in the present invention, the object to be processed is supplied from the upper part of the dryer and is fragmented and dropped in the drying chamber, so that the object to be processed fragmented in a moisture-containing state has a high temperature supplied from the lower part of the drying chamber. It is dried in a short time in contact with hot air, and the temperature of the hot air is lowered. On the other hand, the object to be processed, which has been dried and has a reduced specific gravity, is blown up to the upper part of the drying chamber by a hot air cyclone, and is reliably dried while staying in the upper part of the drying chamber for about 2 to 30 minutes. Here, since the temperature of the hot air on the upper side of the drying chamber is lowered, the object to be processed is prevented from being thermally denatured by being exposed to the hot air for a long time. Therefore, the present invention can be particularly suitably used for drying organic residues such as teacups, okara, and shochu squeezed rice cakes that are reused as objects to be processed.
ここで本明細書において「有機性残渣」とは、茶滓、コーヒー豆滓、焼酎の絞り滓、酒粕等の飲料製造残渣、おからや野菜屑といった食品残渣等、飼料や工業原料として再利用可能な有機性廃棄物を意味するものとする。本発明は特に有機性残渣を再利用するために乾燥させることに適しているが、被処理物は上記有機性残渣に限定されず、食品、飼料および医薬品等の原料を乾燥させることもでき、生ゴミや排水の生物処理により生じる有機性汚泥等の有機性廃棄物、底泥等の無機性廃棄物を被処理物として乾燥させることは排除されない。   In this specification, “organic residue” means reused as feed or industrial raw materials such as tea residue, coffee bean cake, shochu rice cake, beverage manufacturing residue such as sake lees, food residue such as okara and vegetable waste, etc. It shall mean possible organic waste. The present invention is particularly suitable for drying to recycle the organic residue, but the object to be treated is not limited to the above organic residue, and raw materials such as food, feed and medicine can be dried, It is not excluded to dry organic waste such as organic sludge generated by biological treatment of raw garbage and wastewater, and inorganic waste such as bottom mud as the object to be treated.
(2) 前記乾燥室は、円筒の底側端縁が絞られた逆円錐状であることを特徴とする(1)に記載の乾燥装置。   (2) The drying apparatus according to (1), wherein the drying chamber has an inverted conical shape in which a bottom end edge of a cylinder is narrowed.
本発明によれば、乾燥室の形状を熱風が吹き込まれる底部側に向かって細くなる逆円錐形とするため、底側から上昇する熱気流サイクロンを容易に作り出すことができる。   According to the present invention, since the shape of the drying chamber is an inverted conical shape that narrows toward the bottom side into which hot air is blown, a hot airflow cyclone rising from the bottom side can be easily created.
(3) 前記乾燥室は、天井側に設けられ被処理物が供給される供給口と、天井に設けられ当該乾燥室内の気体を排出する排気口と、側壁の底側に設けられ前記熱風発生手段から供給される熱風が吹き込まれる熱風口と、を備え、前記熱風旋回手段は、前記熱風発生手段と前記乾燥室の熱風口とに接続され前記乾燥機本体の略円形になった外縁の接線方向に延びる熱風供給管である(1)または(2)に記載の乾燥装置。   (3) The drying chamber is provided on the ceiling side and supplied with an object to be processed, an exhaust port that is provided on the ceiling and discharges gas in the drying chamber, and the hot air generation is provided on the bottom side of the side wall. A hot air outlet through which hot air supplied from the means is blown, and the hot air swirling means is connected to the hot air generating means and the hot air outlet of the drying chamber, and is tangent to the outer edge of the dryer main body that is substantially circular The drying apparatus according to (1) or (2), which is a hot air supply pipe extending in a direction.
(3)記載の発明では熱風供給管が乾燥機本体の略円形の外縁の接線方向に延びる。すなわち、本発明では熱風供給管が略円形の水平断面を有する乾燥室に対して偏心した状態で取り付けられることにより、熱風が略円形の乾燥室の外壁に沿って旋回して上昇する。このため本発明によれば乾燥機本体や乾燥室の内部に回転手段を設けることなく、乾燥機の構成を簡素化して熱気流サイクロンを発生させることができる。特に、乾燥室の形状を上方に向かって直径が広くなる略円錐状とすると、旋回する熱気流が上昇し易いため、好ましい。   In the invention described in (3), the hot air supply pipe extends in the tangential direction of the substantially circular outer edge of the dryer main body. That is, in the present invention, the hot air supply pipe is attached in an eccentric state with respect to the drying chamber having a substantially circular horizontal cross section, so that the hot air swirls and rises along the outer wall of the substantially circular drying chamber. Therefore, according to the present invention, it is possible to simplify the configuration of the dryer and generate a hot air current cyclone without providing a rotating means inside the dryer body or the drying chamber. In particular, it is preferable that the shape of the drying chamber is a substantially conical shape whose diameter increases toward the upper side, because the swirling hot air flow is likely to rise.
(4) 前記回転手段は、前記回転軸の回転速度を変化させる速度切替機構を備えることを特徴とする(1)から(3)のいずれかに記載の乾燥装置。   (4) The drying device according to any one of (1) to (3), wherein the rotation unit includes a speed switching mechanism that changes a rotation speed of the rotation shaft.
速度切替機構は、運転速度を2段階以上に変化させることができることが好ましい。回転軸の回転速度は、通常処理時は300〜600rpmの高速回転とし、乾燥室の側壁に付着した被処理物を剥離させる場合等は30〜100rpmの緩速運転とすることが好ましい。このように速度切替機構を設けることにより、回転軸を緩速回転させて回転するチェーンの先端の高さを変えることができるため乾燥室側壁に付着した付着物を容易に剥離することができる。   The speed switching mechanism is preferably capable of changing the operating speed in two or more stages. The rotation speed of the rotating shaft is preferably set to a high speed rotation of 300 to 600 rpm during normal processing, and a slow operation of 30 to 100 rpm is preferable when the object to be processed attached to the side wall of the drying chamber is peeled off. By providing the speed switching mechanism in this manner, the height of the tip of the rotating chain can be changed by rotating the rotating shaft at a slow speed, so that the deposits attached to the side wall of the drying chamber can be easily peeled off.
また、回転手段は熱気流サイクロンの旋回方向と逆方向に回転軸を回転させるものであることが好ましく、さらに回転軸の回転方向を正逆切替できることが好ましい。回転軸を熱気流サイクロンの旋回方向と反対に回転させることにより、熱気流サイクロンの流れに乗って流動する被処理物と、この熱気流サイクロンに対向して回転するチェーンとの接触効率が高くなり、被処理物をより迅速に乾燥させることができる。   The rotating means preferably rotates the rotating shaft in the direction opposite to the turning direction of the hot air cyclone, and it is preferable that the rotating direction of the rotating shaft can be switched between forward and reverse. By rotating the rotating shaft in the direction opposite to the swirling direction of the hot-air cyclone, the contact efficiency between the workpiece flowing along the hot-air cyclone flow and the chain rotating opposite the hot-air cyclone increases. The to-be-processed object can be dried more rapidly.

The upper rotor blade is preferably rotated in the same direction as the rotation axis, particularly in the direction opposite to the swirling direction of the hot air cyclone, so as to generate a discharge air swirling in the direction opposite to the hot air cyclone. In addition, in the upper part of the drying chamber, in order to efficiently suck and discharge the discharged airflow with dust, an umbrella-shaped hood that opens downward and opens in the drying chamber and an exhaust pipe that is connected to this hood and extends to the outside through the exhaust port Are preferably provided.
(6) 前記回転手段は、前記回転軸の底側端部に固定された下側回転翼を備えることを特徴とする(1)から(5)のいずれかに記載の乾燥装置。   (6) The drying apparatus according to any one of (1) to (5), wherein the rotating unit includes a lower rotary blade fixed to a bottom side end of the rotating shaft.
さらに回転軸には乾燥室の底部側に下側回転翼を設けることが好ましい。下側回転翼は乾燥機の運転が停止する等して乾燥室の底部に被処理物が堆積したような場合に回転させ、塊状になった被処理物を破砕するとともに上昇気流を発生させることにより、乾燥室底部に堆積した被処理物を舞い上がらせる。下側回転翼は、乾燥室の底部に堆積物が堆積した場合のみ、回転させられればよく、熱気流サイクロンの流れを阻害しないよう、回転軸とは連動せずに動くように構成することが好ましい。   Furthermore, it is preferable to provide a lower rotating blade on the bottom side of the drying chamber on the rotating shaft. The lower rotor blade is rotated when the object to be processed accumulates at the bottom of the drying chamber due to the operation of the dryer being stopped, etc., to crush the aggregated object to be processed and generate an upward air flow Thus, the object to be processed deposited on the bottom of the drying chamber is raised. The lower rotor blade only needs to be rotated when deposits are deposited on the bottom of the drying chamber, and may be configured to move without interlocking with the rotating shaft so as not to hinder the flow of the hot air cyclone. preferable.
(7) 前記乾燥室は、天井側に設けられ被処理物が供給される供給口と、天井に設けられ当該乾燥室内の気体を排出する排気口と、側壁の底側に設けられ前記熱風発生手段から供給される熱風が吹き込まれる熱風口と、を備え、前記乾燥室の供給口に接続され被処理物を脱水して前記乾燥室に供給する脱水機をさらに備えることを特徴とする(1)から(6)のいずれかに記載の乾燥装置。   (7) The drying chamber is provided on the ceiling side and supplied with an object to be processed; an exhaust port provided on the ceiling for exhausting gas in the drying chamber; and a hot air generation provided on the bottom side of the side wall And a dehydrator connected to the supply port of the drying chamber and dehydrated to be processed and supplied to the drying chamber (1). ) To (6).
被処理物は乾燥機に供給する前に脱水して含水率を低下させておくことが好ましく、(7)記載の発明では乾燥機の前段に脱水機を設けて脱水機出口と乾燥室の供給口とを接続する。脱水機で圧搾脱水された被処理物は塊状になって乾燥機の供給口から乾燥室内部に供給されるが、本発明では乾燥室内部に高速回転するチェーンが設けられているため、塊状の被処理物は速やかに砕片化される。   It is preferable that the material to be treated is dehydrated before being supplied to the dryer to reduce the water content. In the invention described in (7), a dehydrator is provided upstream of the dryer to supply the outlet of the dehydrator and the drying chamber. Connect the mouth. The object to be processed, which has been squeezed and dehydrated by the dehydrator, is agglomerated and supplied from the supply port of the dryer to the inside of the drying chamber.

乾燥機からは水分を含んだ排出気体とともに被処理物が乾燥されて得られる乾燥処理物が粉塵として排出されるため、乾燥機後段には粉塵分離機を設け、粉塵と気体とを分離することが好ましい。粉塵分離機は、排出気体が分離室内部を旋回して下降するサイクロン分離機で構成することができる。サイクロン分離機は、気体と粉塵とが分離される分離室を備える本体と、本体下部側に連結され乾燥処理物が集積される集積槽と、本体上部側に接続され粉塵が除去された含湿気体を排出する含湿気体管と、を備えることが好ましい。   Since the dried processed product obtained by drying the object to be processed together with the exhaust gas containing moisture is discharged as dust from the dryer, a dust separator is provided at the subsequent stage of the dryer to separate dust and gas. Is preferred. The dust separator can be composed of a cyclone separator in which exhaust gas swirls and descends in the separation chamber. The cyclone separator is composed of a main body having a separation chamber in which gas and dust are separated, a collecting tank connected to the lower part of the main body to accumulate dried processed products, and a moisture-containing air connected to the upper part of the main body to remove dust. It is preferable to provide a moisture-containing gas pipe for discharging the body.
(9) 前記粉塵分離手段の後段に設けられて前記含湿気体を冷却して除湿して乾燥気体を得る除湿機をさらに備え、前記除湿機と前記熱風発生手段とは、前記除湿機から排出される乾燥気体を前記熱風発生手段に循環させる気体循環配管で接続されていることを特徴とする(8)に記載の乾燥装置。   (9) The apparatus further comprises a dehumidifier provided downstream of the dust separation means to obtain a dry gas by cooling and dehumidifying the moisture-containing gas, and the dehumidifier and the hot air generating means are discharged from the dehumidifier The drying apparatus according to (8), wherein the drying apparatus is connected by a gas circulation pipe for circulating the dried gas to the hot air generating means.
(9)記載の発明では、粉塵分離機の後段に含湿気体から水分を除去する除湿機を設けるとともに、この除湿機で除湿された乾燥気体の大部分を熱風発生手段に循環させる。すなわち、乾燥気体の一部は乾燥装置の系外へ排出するとともに熱風発生手段には外気の一部を新たに供給するようにしてもよいが、除湿された乾燥気体の大部分(例えば90〜99容量%)は熱風発生手段に循環させることが好ましい。このような循環は特に、空気や熱で酸化劣化する成分を含有する場合に有効である。   In the invention described in (9), a dehumidifier for removing moisture from the moisture-containing gas is provided at the subsequent stage of the dust separator, and most of the dry gas dehumidified by the dehumidifier is circulated to the hot air generating means. That is, a part of the dry gas may be discharged out of the system of the drying apparatus and a part of the external air may be newly supplied to the hot air generating means, but most of the dehumidified dry gas (for example, 90 to 90%). 99% by volume) is preferably circulated to the hot air generating means. Such circulation is particularly effective when it contains components that are oxidized and deteriorated by air or heat.
このように乾燥装置を略閉鎖系として乾燥機で使用される気体を乾燥装置内で循環させることにより、乾燥機に供給される気体の酸素含有量を低下させ、被処理物の酸化を防止できる。また、外気の温度や湿度の変化に係らず、年間を通してほぼ一定の温度および湿度の気体を熱風発生手段に供給できるため、熱風発生手段で気体を加熱するために必要なエネルギー量を低下させることができる。さらに、熱風発生手段から供給される熱風の温度および湿度が年間を通じて安定するため、被処理物の性状が安定する。また、微細な粉塵が排出されることなく、作業環境も良好となる。   As described above, the gas used in the dryer is circulated in the dryer using the drying device as a substantially closed system, thereby reducing the oxygen content of the gas supplied to the dryer and preventing oxidation of the workpiece. . In addition, since the gas with a constant temperature and humidity can be supplied to the hot air generating means throughout the year regardless of changes in the temperature and humidity of the outside air, the amount of energy required to heat the gas with the hot air generating means must be reduced. Can do. Furthermore, since the temperature and humidity of the hot air supplied from the hot air generating means are stable throughout the year, the properties of the workpiece are stabilized. Also, the working environment is improved without discharging fine dust.

FIG. 1 is a schematic view of a drying apparatus 1 according to an embodiment of the present invention. The drying apparatus 1 includes a dehydrator 12, a dryer 14, a dust separator 16, and a dehumidifier 18 connected in this order. As shown in FIG. 1, the dryer 14 has a drying chamber 151 formed in a substantially conical shape by constricting one end of the cylinder. The dryer 14 is an inverted cone type that is installed in a state where the cone is inverted with the one side end portion side of the drying chamber 151 being the bottom side. Hereinafter, terms indicating directions such as up, down, left, and right are used for convenience on the basis of the case where the dryer 14 is installed in this state. Moreover, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted or simplified.
脱水機12はホッパ121と、このホッパ121と接続され内部にスクリュウ126を備える脱水機本体122と、を有する。ホッパ121にはベルトコンベア等で構成される供給機構125から茶飲料製造過程で発生する茶滓等が被処理物として供給される。ホッパ121に供給された被処理物は自然落下またはホッパ121内に設けられたスクリュウ(図示せず)等により所定量ずつ、脱水機本体122に送られる。   The dehydrator 12 includes a hopper 121 and a dehydrator main body 122 that is connected to the hopper 121 and includes a screw 126 inside. The hopper 121 is supplied with teacups and the like generated during the tea beverage production process as a processing object from a supply mechanism 125 constituted by a belt conveyor or the like. The object to be processed supplied to the hopper 121 is sent to the dehydrator main body 122 by a predetermined amount by natural dropping or a screw (not shown) provided in the hopper 121.
脱水機本体122は本実施形態では水平方向に延びる略円筒形の内部空間を備え、この内部空間に設けられたスクリュウ126がモータ等の駆動手段127と接続されている。脱水機本体122に供給された被処理物は、スクリュウ126が駆動手段127で回転されることにより、被処理物を一端側から他端側に移動させながら圧搾脱水される。本実施形態では脱水機12はスクリュウプレス型脱水機として構成されているが、脱水機12はこれに限定されず、例えば遠心濾過型および遠心沈降型の遠心脱水機、ベルトプレス型脱水機、並びにフィルタープレス型等、任意の脱水機を用いることができる。   In the present embodiment, the dehydrator main body 122 includes a substantially cylindrical inner space extending in the horizontal direction, and a screw 126 provided in the inner space is connected to driving means 127 such as a motor. The object to be processed supplied to the dehydrator main body 122 is squeezed and dehydrated while the object to be processed is moved from one end side to the other end side when the screw 126 is rotated by the driving means 127. In this embodiment, the dehydrator 12 is configured as a screw press type dehydrator. However, the dehydrator 12 is not limited to this, and for example, centrifugal filtration type and centrifugal sedimentation type centrifugal dehydrators, belt press type dehydrators, and Any dehydrator such as a filter press mold can be used.
スクリュウ126の下部には網状体128が設けられ、被処理物から脱水された脱水濾液は網状体128を通過して排水口129から排出される。一方、脱水された被処理物は塊状で乾燥機14に供給される。   A mesh body 128 is provided below the screw 126, and the dehydrated filtrate dehydrated from the object to be processed passes through the mesh body 128 and is discharged from the drain outlet 129. On the other hand, the dehydrated material is supplied in a lump form to the dryer 14.
図2は乾燥機14の内部構成を示す斜視図である。乾燥機14は乾燥機本体142と、この乾燥機本体142に接続される熱風発生手段141と、熱風旋回手段としての熱風供給管143と、を備える。乾燥機本体142の内部には、略円筒形の上部乾燥室151aおよび略円錐形の下部乾燥室151bとから構成される乾燥室151が形成されている。熱風発生手段141は、気体を間接加熱する加熱器131と、加熱器で加熱された熱風を乾燥室151に送る送風器であるファン132と、で構成されている。   FIG. 2 is a perspective view showing the internal configuration of the dryer 14. The dryer 14 includes a dryer main body 142, hot air generating means 141 connected to the dryer main body 142, and hot air supply pipes 143 as hot air swirling means. Inside the dryer main body 142 is formed a drying chamber 151 composed of a substantially cylindrical upper drying chamber 151a and a substantially conical lower drying chamber 151b. The hot air generating means 141 includes a heater 131 that indirectly heats a gas, and a fan 132 that is a blower that sends hot air heated by the heater to the drying chamber 151.
熱風発生手段141は加熱器131を挟んでファン132と反対側に位置する熱風供給管143と接続されており、加熱器131で加熱された熱風はファン132により乾燥室151に吹き込まれる。熱風供給管143は本実施形態ではすり鉢状になった下部乾燥室151bの最下部近傍において、乾燥機本体142の略円形の外縁の接線方向に延びる。すなわち熱風供給管143は、乾燥室151の垂直方向中心線より壁側に偏った位置に熱風を供給するように接続されている。   The hot air generating means 141 is connected to a hot air supply pipe 143 located on the opposite side of the fan 132 with the heater 131 interposed therebetween, and the hot air heated by the heater 131 is blown into the drying chamber 151 by the fan 132. The hot air supply pipe 143 extends in the tangential direction of the substantially circular outer edge of the dryer main body 142 in the vicinity of the lowermost portion of the lower drying chamber 151b which is shaped like a mortar in this embodiment. That is, the hot air supply pipe 143 is connected to supply hot air to a position that is biased toward the wall side from the vertical center line of the drying chamber 151.
乾燥室151には水平断面積が大きくなった側(天井側)の側壁に供給口155、水平断面積が狭くなった側(底部側)の側壁に熱風口157、および天井となる端面に排気口159が形成されている。供給口155は脱水機12の出口と接続され、熱風口157は熱風供給管143を介して熱風発生手段141と接続されている。また、排気口159からは後述する排気管172が延びて乾燥機14と粉塵分離機16とが接続されている。   The drying chamber 151 has a supply port 155 on the side wall on the side with the larger horizontal cross-sectional area (ceiling side), a hot air port 157 on the side wall on the side with the smaller horizontal cross-sectional area (bottom side), and an exhaust on the end surface that becomes the ceiling. A mouth 159 is formed. The supply port 155 is connected to the outlet of the dehydrator 12, and the hot air port 157 is connected to the hot air generating means 141 via the hot air supply pipe 143. Further, an exhaust pipe 172 described later extends from the exhaust port 159, and the dryer 14 and the dust separator 16 are connected.
乾燥機本体142は、乾燥室151内の略中心に設けられ略垂直方向に延びる回転軸152と、この回転軸を回転させる回転手段と153と、前記回転軸152に一端縁が固定された複数のチェーン154と、を備える。チェーン154の長さは、回転軸152から乾燥室151側壁までの距離より5〜10mm程度短く、本実施形態では乾燥室151は底部側に向かって先が細くなっているため、回転軸152の異なる高さ位置に固定された複数のチェーン154の長さは互いに異なり、具体的には底部側に向かって短くなる。   The dryer main body 142 includes a rotating shaft 152 provided substantially at the center in the drying chamber 151 and extending in a substantially vertical direction, a rotating unit 153 for rotating the rotating shaft, and a plurality of end edges fixed to the rotating shaft 152. The chain 154 is provided. The length of the chain 154 is about 5 to 10 mm shorter than the distance from the rotating shaft 152 to the side wall of the drying chamber 151. In this embodiment, the drying chamber 151 is tapered toward the bottom side. The lengths of the plurality of chains 154 fixed at different height positions are different from each other, specifically, become shorter toward the bottom side.
回転軸152の両端部側にはそれぞれ、下側回転翼133と上側回転翼135とが設けられ、これらの回転翼133、135はどちらも4枚の羽が約90°の角度で取り付けられた構成である。各羽は、いずれも同じ方向、具体的には上側回転翼133側端縁に向かって傾斜するように回転軸152の軸が延びる方向に対して45°程度の角度で取り付けられている。   A lower rotary blade 133 and an upper rotary blade 135 are provided on both ends of the rotary shaft 152, respectively. Each of these rotary blades 133 and 135 has four blades attached at an angle of about 90 °. It is a configuration. Each wing is attached at an angle of about 45 ° with respect to the direction in which the axis of the rotary shaft 152 extends so as to incline toward the edge in the same direction, specifically the upper rotor blade 133 side.
回転軸152は上側回転翼135が設けられた側を上側(天井側)として乾燥室151内部に取り付けられ、両回転翼133、135はどちらも乾燥室151内に上向流を発生させる。回転軸152は等間隔で取り付けられた3枚の軸受板158で支持されている。軸受板158は、乾燥室151内部の気流の流れを阻害しないように、回転軸152に軸が延びる方向に対して30〜60°、例えば本実施形態では45°程度傾いて斜めになった状態で乾燥室151の側壁に取り付けられている。   The rotating shaft 152 is attached to the inside of the drying chamber 151 with the side on which the upper rotating blades 135 are provided as the upper side (ceiling side), and both the rotating blades 133 and 135 generate an upward flow in the drying chamber 151. The rotating shaft 152 is supported by three bearing plates 158 attached at equal intervals. The bearing plate 158 is inclined at an angle of 30 to 60 °, for example, about 45 ° in this embodiment, with respect to the direction in which the shaft extends to the rotation shaft 152 so as not to hinder the flow of the airflow inside the drying chamber 151. And attached to the side wall of the drying chamber 151.
なお乾燥機12を稼動させて乾燥処理を行なう際は、回転軸152は後述する熱気流サイクロンの旋回方向と逆に回転させることから、下側回転翼133は回転軸152とは独立に回転されるよう、構成することが好ましい。すなわち、通常の乾燥処理の際には下側回転翼133は回転させないことが好ましい。   When the dryer 12 is operated to perform the drying process, the rotating shaft 152 is rotated in the direction opposite to the swirling direction of the hot air cyclone described later, so that the lower rotary blade 133 is rotated independently of the rotating shaft 152. It is preferable to configure so that. That is, it is preferable not to rotate the lower rotary blade 133 during a normal drying process.
このためには、例えば回転軸152を覆う略円筒状の管体152bを設けて回転軸152の一部を二重構造とし、この管体152bに下側回転翼133を固定すればよい。また、管体152bには回転軸152と逆方向にこの管体152bを回転させる駆動手段(図示せず)を回転手段153とは別に接続してもよい。このように管体152bに駆動手段を設けて下側回転翼133を回転軸152と逆方向に回転させる場合、下側回転翼133は回転軸152と逆方向に旋回する熱気流サイクロンを形成するため下側回転翼133と、管体152bと、駆動手段とで熱風旋回手段を構成することもできる。   For this purpose, for example, a substantially cylindrical tube body 152b that covers the rotation shaft 152 is provided, a part of the rotation shaft 152 has a double structure, and the lower rotary blade 133 is fixed to the tube body 152b. Further, a driving means (not shown) for rotating the tube body 152b in the direction opposite to the rotation shaft 152 may be connected to the tube body 152b separately from the rotation means 153. In this way, when the driving means is provided in the tube body 152b and the lower rotary blade 133 is rotated in the direction opposite to the rotary shaft 152, the lower rotary blade 133 forms a hot air current cyclone that rotates in the direction opposite to the rotary shaft 152. Therefore, the hot air swirling means can be constituted by the lower rotary blade 133, the tube body 152b, and the driving means.
回転手段153はモータ等の駆動手段で構成され、本発明では熱風発生手段141のファン132と連動して回転軸152の回転速度をインバータ制御する制御機能を備える速度切替機構(図示せず)がモータに取り付けられた構成となっている。本実施形態では、回転手段153はインバータ制御により、回転軸152の回転速度を任意に変更できるように構成されているが、回転速度は少なくとも2段階で変化させられればよい。   The rotating means 153 is composed of a driving means such as a motor. In the present invention, a speed switching mechanism (not shown) having a control function for controlling the rotational speed of the rotating shaft 152 in conjunction with the fan 132 of the hot air generating means 141 is provided. The configuration is attached to the motor. In the present embodiment, the rotation means 153 is configured to be able to arbitrarily change the rotation speed of the rotating shaft 152 by inverter control, but the rotation speed may be changed in at least two stages.
乾燥室151内部にはまた、先端に向かって広がったフード171が一端に接続された排気管172が延びている。排気管172は排気口159から乾燥室151外部に延伸して、他端側が粉塵分離機16に接続されている。粉塵分離機16は乾燥機14と同様に下部側が次第に細くなったすり鉢状の底部を備える分離室161が設けられた分離機本体162と、分離機本体162の下部に設けられた集積槽163と、分離機本体162上部から延伸する含湿気体管164と、を備える。   An exhaust pipe 172 connected to one end of a hood 171 that spreads toward the front end also extends inside the drying chamber 151. The exhaust pipe 172 extends from the exhaust port 159 to the outside of the drying chamber 151, and the other end is connected to the dust separator 16. The dust separator 16 has a separator main body 162 provided with a separation chamber 161 having a mortar-shaped bottom portion that gradually becomes thinner like the dryer 14, and a collecting tank 163 provided at the lower part of the separator main body 162. And a humidified gas pipe 164 extending from the upper part of the separator main body 162.
排気管172は分離室161の上部側側壁に接続され、含湿気体管164は分離室161の天井に接続され、排気管172から供給され粉塵を含む気体は、分離室161内を旋回しながら下降する。気体の風速は下方に向かって低下し、気体とともに乾燥機14から排出された乾燥処理物と分離され、除塵された気体(含湿気体)は水分を含んだ状態であり、含湿気体管164から除湿機18に送られる。   The exhaust pipe 172 is connected to the upper side wall of the separation chamber 161, the moisture-containing gas pipe 164 is connected to the ceiling of the separation chamber 161, and the gas containing dust supplied from the exhaust pipe 172 swirls in the separation chamber 161. Descend. The wind speed of the gas decreases downward, is separated from the dried processed product discharged from the dryer 14 together with the gas, and the dust-removed gas (humid gas) is in a state containing moisture. To the dehumidifier 18.
除湿機18は冷却機構を備える熱交換器であり、含湿気体が冷却されることにより水分が除去された乾燥気体が得られる。除湿機18により含湿気体が冷却されて得られる凝縮水は排水管から排出し、乾燥された気体は気体循環配管19から熱風発生手段141に循環させる。   The dehumidifier 18 is a heat exchanger having a cooling mechanism, and a dry gas from which moisture has been removed is obtained by cooling the moisture-containing gas. Condensed water obtained by cooling the moisture-containing gas by the dehumidifier 18 is discharged from the drain pipe, and the dried gas is circulated from the gas circulation pipe 19 to the hot air generating means 141.
以下、本実施形態に係る乾燥装置1を用いて、被処理物として茶滓を乾燥させる乾燥方法について説明する。まず、茶飲料の製造過程から排出される茶滓(含水率70〜85%程度)を供給機構125からホッパ121に送り、ホッパ121から所定量ずつ、脱水機本体122内部に導入する。脱水機12内部では、茶滓は駆動手段127で回転されるスクリュウ126の回転に伴って図1の右側方向に送られる過程で圧搾脱水される。脱水濾液は網状体128から落下して排水口129から排出される。一方、茶滓は含水率75%程度に脱水され、直径2〜10cm程度の塊状となって供給口155から乾燥機14の乾燥室151内に入る。   Hereinafter, the drying method which dries a teacup as a to-be-processed object using the drying apparatus 1 which concerns on this embodiment is demonstrated. First, teacups (water content of about 70 to 85%) discharged from the tea beverage production process are sent from the supply mechanism 125 to the hopper 121 and introduced into the dehydrator main body 122 from the hopper 121 by a predetermined amount. Inside the dehydrator 12, the tea bowl is squeezed and dehydrated in the process of being sent in the right direction in FIG. 1 as the screw 126 rotated by the driving means 127 rotates. The dehydrated filtrate falls from the mesh body 128 and is discharged from the drain outlet 129. On the other hand, the tea bowl is dehydrated to a moisture content of about 75% and becomes a lump with a diameter of about 2 to 10 cm and enters the drying chamber 151 of the dryer 14 from the supply port 155.
乾燥室151には熱風供給管143から熱風が供給されるとともに、回転軸152が回転されることでチェーン154が回転して塊状の茶滓は打撃破砕されて砕片化しながら乾燥室151を落下する。ここで、熱風供給管143は乾燥機本体142の底部側壁において、水平断面が略円形となった乾燥室内部に接線方向から熱風を供給するように設けられている。このため、熱風供給管143から送り込まれた熱風は、熱風口157近傍で乾燥室151側壁に接して旋回流となって乾燥室151内を上昇する。本実施形態では下部乾燥室151bは上方に向かって広くなる略円錐形であるため、熱風供給管143を乾燥機本体142の接線方向に延びるように取り付けることで、熱風は容易に旋回する上昇気流(熱気流サイクロン)となる。   Hot air is supplied to the drying chamber 151 from the hot air supply pipe 143, and the rotating shaft 152 is rotated, whereby the chain 154 is rotated, and the lump-shaped teacup is blown and crushed and falls into the drying chamber 151 while being crushed. . Here, the hot air supply pipe 143 is provided on the bottom side wall of the dryer main body 142 so as to supply hot air from the tangential direction to the inside of the drying chamber having a substantially circular horizontal cross section. For this reason, the hot air sent from the hot air supply pipe 143 comes into contact with the side wall of the drying chamber 151 in the vicinity of the hot air outlet 157 and turns up in the drying chamber 151. In this embodiment, the lower drying chamber 151b has a substantially conical shape that widens upward, so that the hot air can be easily swirled by attaching the hot air supply pipe 143 so as to extend in the tangential direction of the dryer main body 142. (Hot air cyclone).
本実施形態では、熱風供給管143は乾燥室151の垂直方向中心から右側に偏った位置に熱風を供給するように接続されており、ファン132から送られた熱風は、図中、矢印で示すように左回りに旋回して上昇する熱気流サイクロンとなる。一方、回転軸152は右回りに回転され、チェーン154は右回りに回って熱気流サイクロンと対向する。乾燥室151内に供給された茶滓は熱気流サイクロンに乗って左回りに旋回しながら右回りに回転するチェーン154と接触する。このため、本実施形態の乾燥装置1では茶滓とチェーンとの接触頻度が多く、茶滓が迅速に砕片化される。   In the present embodiment, the hot air supply pipe 143 is connected so as to supply hot air to a position biased to the right side from the vertical center of the drying chamber 151, and the hot air sent from the fan 132 is indicated by an arrow in the figure. Thus, it becomes a hot air current cyclone that turns counterclockwise and rises. On the other hand, the rotating shaft 152 is rotated clockwise, and the chain 154 rotates clockwise to face the hot air cyclone. The tea bowl supplied into the drying chamber 151 contacts a chain 154 that rotates clockwise while turning counterclockwise on a hot air current cyclone. For this reason, in the drying apparatus 1 of this embodiment, the contact frequency of the teacup and the chain is high, and the teacup is quickly broken into pieces.
砕片化された茶滓は表面から乾燥され、乾燥が進んで粉末状になった茶滓は熱気流サイクロンに巻き上げられて乾燥室151上部に浮上して略円筒状の上部乾燥室151aに2〜30分程度、滞留する。一方、水分を含んだ塊状の茶滓は下部乾燥室151bの下方に落下して破砕されながら高温の熱気流サイクロンと接触することで水分が蒸発して乾燥されるとともに熱風の温度を95℃程度に低下させる。   The crushed teacup is dried from the surface, and the dried teacup is pulverized into a hot air current cyclone and floats on the upper portion of the drying chamber 151 to enter a substantially cylindrical upper drying chamber 151a. It stays for about 30 minutes. On the other hand, the massive teacup containing water drops below the lower drying chamber 151b and is crushed while coming into contact with a high-temperature hot-air cyclone to evaporate the water and dry the hot-air temperature at about 95 ° C. To lower.
このように、本発明では水分を多く含む茶滓は乾燥室151の底部側で高温(例えば150〜250℃程度)の熱風と接触して瞬時に乾燥される一方、乾燥された茶滓は粉塵となって上部乾燥室151a側に舞い上がり、比較的低温(例えば80〜95℃程度)の熱気流サイクロンでさらに乾燥される。本実施形態では、下部乾燥室151bの垂直方向の高さは2〜5mであり、上部乾燥室151aの高さは1〜2mで、上部乾燥室151a側に舞い上げられた乾燥処理物は上部乾燥室151aで確実に乾燥される。このため、本発明によれば茶滓を短時間で確実に乾燥させ、しかも熱風によるカテキン等の分解を抑制することができる。   As described above, in the present invention, a teacup containing a lot of water is dried on the bottom side of the drying chamber 151 in contact with hot air of high temperature (for example, about 150 to 250 ° C.), while the dried teacup is dusty. Then, it rises to the upper drying chamber 151a side, and is further dried by a relatively low temperature (for example, about 80 to 95 ° C.) hot air current cyclone. In the present embodiment, the height of the lower drying chamber 151b in the vertical direction is 2 to 5 m, the height of the upper drying chamber 151a is 1 to 2 m, and the dried processed product raised to the upper drying chamber 151a side is the upper portion. It is surely dried in the drying chamber 151a. For this reason, according to this invention, a teacup can be dried reliably in a short time, and also decomposition | disassembly of catechin etc. by a hot air can be suppressed.
上部乾燥室151aは熱気流サイクロンの風速が低いため、上部乾燥室151aを浮遊する乾燥処理物はフード171下方に設けられた上側回転翼135に発生される排出気流に乗って排気管172から排出される。上側回転翼135は熱気流サイクロンとは逆向きの排出気流を生じることにより、上側回転翼135付近を浮遊する乾燥処理物を吸い込みながら排気管172に送る。ここで、乾燥室151は外縁付近ほど、風速が速く、中心部は風速が低くなっていることから、上部乾燥室151aの中心付近の気流は弱く、乾燥が進んで軽くなった粉塵が選択的に排気管172に吸い込まれることになる。このため、本発明によれば排気管172から排出される乾燥処理物の品質を均質化できる。   Since the upper drying chamber 151 a has a low wind speed of the hot air flow cyclone, the dried product floating in the upper drying chamber 151 a is discharged from the exhaust pipe 172 on the exhaust air flow generated in the upper rotor blade 135 provided below the hood 171. Is done. The upper rotor blade 135 generates a discharge airflow opposite to that of the thermal airflow cyclone, so that the dried processed material floating in the vicinity of the upper rotor blade 135 is sucked and sent to the exhaust pipe 172. Here, since the wind speed in the drying chamber 151 is higher near the outer edge and the wind speed is lower in the center, the airflow near the center of the upper drying chamber 151a is weak, and the dust that has become lighter as the drying progresses is selective. Into the exhaust pipe 172. For this reason, according to this invention, the quality of the dried processed material discharged | emitted from the exhaust pipe 172 can be homogenized.
排気管172から粉塵分離機16に入った乾燥処理物は、粉塵分離機16内を旋回して下降する気流の勢いが弱まるとともに自然落下して集積槽163に堆積する。一方、乾燥処理物と分離され除塵された気体は水分を含んでおり、含湿気体管164から排出されファン165を介して除湿機18に供給される。除湿機18では冷却水等の冷却媒体を用いて含湿気体を間接冷却することにより、含湿気体に含まれる水分を凝縮させて、水分を凝縮水として系外へ排出し、水分が除去されて温度40〜60℃程度、湿度20〜50%程度になった乾燥気体を得る。   The dried processed material that has entered the dust separator 16 from the exhaust pipe 172 weakens the momentum of the airflow swirling and descending in the dust separator 16 and spontaneously falls and accumulates in the accumulation tank 163. On the other hand, the gas that has been separated from the dried product and dedusted contains moisture, and is discharged from the moisture-containing gas pipe 164 and supplied to the dehumidifier 18 via the fan 165. In the dehumidifier 18, the moisture-containing gas is indirectly cooled using a cooling medium such as cooling water to condense the moisture contained in the moisture-containing gas, and the moisture is discharged out of the system as condensed water, and the moisture is removed. Thus, a dry gas having a temperature of about 40 to 60 ° C. and a humidity of about 20 to 50% is obtained.
本実施形態では、除湿機18と熱風発生手段141とは気体循環配管19を介して接続されており、除湿機18で得られた乾燥気体はほとんどが熱風発生手段141に送られ、加熱されて熱風として乾燥室151内に循環供給される。本発明では乾燥用の気体が循環利用されるため、熱風発生手段141に供給される気体の温度および湿度が年間を通して上記範囲内でほぼ一定となる。このため、気体加熱用のエネルギー消費を低減できるとともに、乾燥室151内の処理条件を安定化させることができる。また、循環される気体は酸素含有量が低いため、茶滓等の被処理物の酸化を抑制できる。このため、本発明によれば乾燥処理物の品質を安定させ、品質劣化を抑制することができる。なお、被処理物の酸化が問題とならない場合は、除湿機18を用いることなく直接排出する方が有利である。   In the present embodiment, the dehumidifier 18 and the hot air generating means 141 are connected via the gas circulation pipe 19, and most of the dry gas obtained by the dehumidifier 18 is sent to the hot air generating means 141 and heated. It is circulated and supplied into the drying chamber 151 as hot air. In the present invention, since the drying gas is circulated and used, the temperature and humidity of the gas supplied to the hot air generating means 141 are substantially constant within the above range throughout the year. For this reason, energy consumption for gas heating can be reduced, and the processing conditions in the drying chamber 151 can be stabilized. In addition, since the circulated gas has a low oxygen content, oxidation of an object to be processed such as teacups can be suppressed. For this reason, according to this invention, the quality of a dried processed material can be stabilized and quality deterioration can be suppressed. In addition, when the oxidation of a to-be-processed object does not become a problem, it is advantageous to discharge | emit directly, without using the dehumidifier 18. FIG.
本実施形態では被処理物として茶滓を用いるが、茶滓は粒径が比較的均一で種々の含有成分を含むため、乾燥室151内に付着しやすい。特に、多段に設けられたチェーン154同士の間に位置する乾燥室151の壁面には茶滓が付着した塊が成長する場合がある。本発明ではかかる場合に、回転軸152の回転速度を緩速運転に切替ることでチェーン154の遊離端が回転する高さを変化させて壁面に付着した茶滓の塊を落下させる。   In the present embodiment, a teacup is used as an object to be processed, but the teacup has a relatively uniform particle size and includes various components, and thus tends to adhere to the drying chamber 151. In particular, a lump with teacups may grow on the wall surface of the drying chamber 151 located between the chains 154 provided in multiple stages. In such a case, the present invention changes the height at which the free end of the chain 154 rotates by switching the rotational speed of the rotating shaft 152 to a slow speed operation, and drops the bowl of teacups attached to the wall surface.
図3は緩速運転を行っている状態の乾燥機14の断面模式図である。図3に示すように緩速運転を行っている際には、回転軸152の回転速度を低下させてチェーン154と回転軸152との角度を30〜50°程度にすることにより、チェーンの154の先端が位置する高さを変化させている。乾燥室151の側壁には、通常の乾燥処理の際にチェーン154の先端が位置する高さにある側壁部分を除き、茶滓20が付着しているが、緩速運転を行うことにより、この茶滓20とチェーン154とが接触して茶滓20の塊が破砕される。   FIG. 3 is a schematic cross-sectional view of the dryer 14 in a state where a slow speed operation is performed. As shown in FIG. 3, when performing a slow speed operation, the rotational speed of the rotating shaft 152 is decreased to make the angle between the chain 154 and the rotating shaft 152 be about 30 to 50 °, so that the chain 154 The height where the tip of is located is changed. On the side wall of the drying chamber 151, the teacup 20 is attached except for the side wall portion at the height where the tip of the chain 154 is positioned in the normal drying process. The bowl 20 and the chain 154 come into contact with each other and the lump of the bowl 20 is crushed.
また、回転軸152の回転を停止するとチェーン154は回転軸152に沿って垂下するため、回転軸152にと乾燥室151の側壁とを洗浄液で洗浄すれば、乾燥室151内とチェーン154および回転軸152とを同時に洗浄できる。   Further, when the rotation of the rotating shaft 152 is stopped, the chain 154 hangs down along the rotating shaft 152. Therefore, if the rotating shaft 152 and the side wall of the drying chamber 151 are washed with the cleaning liquid, the inside of the drying chamber 151, the chain 154, and the rotation The shaft 152 can be cleaned at the same time.
なお、停電等により乾燥機14が停止して運転を再開する場合等、乾燥室151の底部に茶滓が塊状に堆積しているような場合、下側回転翼133を回転させる。これにより、堆積物を砕片化するとともに上昇気流により茶滓を乾燥室151上部側へ巻き上げる。下側回転翼133は熱気流サイクロンの動きを阻害しないよう、回転軸152から独立して回転することが好ましいが、熱風の吹き込み量を調整する等して下側回転翼133を動かしながら熱気流サイクロンを作り出して乾燥処理を行なうことも排除されない。   When the dryer 14 is stopped due to a power failure or the like and the operation is restarted, such as when the bowl is accumulated in the bottom of the drying chamber 151, the lower rotary blade 133 is rotated. As a result, the deposit is broken up and the teacup is wound up to the upper side of the drying chamber 151 by the rising airflow. The lower rotor 133 preferably rotates independently from the rotary shaft 152 so as not to hinder the movement of the hot air cyclone, but the hot air current is adjusted while moving the lower rotor 133 by adjusting the amount of hot air blown in. It is not excluded to create a cyclone and perform a drying process.
