Description

本発明は、茶葉を焙煎する装置に関するものである。   The present invention relates to an apparatus for roasting tea leaves.

製茶加工された茶葉は、その後、火入れや選別などの仕上げ加工を行なう。煎茶の場合は、茶葉温度が１００度前後になるように２０〜３０分程度加熱し、火入れを行なう。仕上げ加工には、煎茶を強く火入れして、番茶や焙じ茶とするものがある。番茶の場合は煎茶より少し高温で加熱し、焙じ茶の場合は２００〜３００度くらいの高温で、焙じ香が生成するまで（約１分程度）加熱する。これを焙煎という。高温で焙煎するためには、品質管理に経験と優れた感を有する。   The tea leaves that have been made are then subjected to finishing processing such as burning and sorting. In the case of sencha, the tea leaves are heated for about 20 to 30 minutes so that the temperature of the tea leaves is around 100 degrees and then fired. In finishing processing, Sencha is ignited strongly to make bancha or roasted tea. In the case of bancha, it is heated at a slightly higher temperature than sencha, and in the case of roasted tea, it is heated at a high temperature of about 200 to 300 degrees until roasting incense is formed (about 1 minute). This is called roasting. In order to roast at high temperature, it has experience and excellent feeling in quality control.

一般的な火入れ機では、設定できる温度が低く（１００度前後）、低い温度で長時間加熱しても焙煎を良好に行なうことはできないため、通常、焙煎は特許文献１、２のような焙煎専用の装置で行なっていた。   In general fire-extinguishing machines, the temperature that can be set is low (around 100 degrees), and roasting cannot be performed well even when heated at a low temperature for a long time. It was done with a device dedicated to roasting.

特許文献１の装置に遠赤外線発生器が設置されていない装置の場合、金属製の円筒形の処理ドラムを外側から加熱する方法は茶葉にとっては間接加熱であり、処理ドラムばかりではなく、周囲も加熱の影響を受けるので加熱ロスが多く、所定温度に達するまでの時間的ロスもあった。   In the case where the far-infrared generator is not installed in the apparatus of Patent Document 1, the method of heating the metal cylindrical processing drum from the outside is indirect heating for tea leaves, and not only the processing drum but also the surroundings. Due to the influence of heating, there were many heating losses, and there was also a time loss until reaching a predetermined temperature.

そのため、特許文献２のような装置も考案されているが、遠赤外線発生体が高価だったり、処理ドラムの内部に遠赤外線発生体を設置するために邪魔だったりしていた。   For this reason, an apparatus such as Patent Document 2 has been devised, but the far-infrared ray generator is expensive, or it is obstructive to install the far-infrared ray generator inside the processing drum.

また、いずれの場合も茶葉から蒸散する水分を外部に排出するために換気ファンを回しており、この設備や電力が必要だった。   In both cases, the ventilation fan was turned on to discharge the water transpiration from the tea leaves to the outside, and this equipment and power were necessary.

本発明は、上記の問題を解決するため、熱効率がよい茶葉焙煎機を提供することを課題としている。   In order to solve the above problems, an object of the present invention is to provide a tea leaf roasting machine having high thermal efficiency.

本発明の第１手段の茶葉焙煎機は、一方を茶葉投入口、他方を茶葉排出口とする円筒形の処理ドラムと、該処理ドラムの内側に備えて茶葉を拡散するための茶葉拡散突起と、前記処理ドラムを回転させる駆動手段と、前記処理ドラムを外側から加熱する熱源とより構成するとともに、前記処理ドラムの少なくとも一部を通気性部材で形成し、熱源の熱が前記処理ドラム内の茶葉に当たるように茶葉を焙煎する。第２手段は、前記第１手段において、前記処理ドラムの温度と処理中の茶葉温度を計測する温度計測手段を設ける。第３手段は、前記第１または２手段において、前記処理ドラムの傾斜角を任意に調節するための角度調節手段を設ける。第４手段は、前記第１、２または３手段において、前記茶葉投入口の上方に定量供給装置を設ける。   The tea leaf roasting machine of the first means of the present invention comprises a cylindrical processing drum having one tea leaf inlet and the other tea leaf outlet, and a tea leaf diffusion protrusion for diffusing tea leaves provided inside the processing drum. And a driving means for rotating the processing drum, and a heat source for heating the processing drum from the outside, and at least a part of the processing drum is formed of a gas permeable member, and the heat of the heat source is generated in the processing drum. Roast tea leaves to hit the tea leaves. The second means includes temperature measuring means for measuring the temperature of the processing drum and the temperature of the tea leaf being processed in the first means. The third means includes an angle adjusting means for arbitrarily adjusting an inclination angle of the processing drum in the first or second means. A 4th means provides a fixed_quantity | feed_rate supply apparatus above the said tea leaf slot in the said 1st, 2nd, or 3rd means.

本発明の装置により、熱源の熱が直接処理ドラムの中の茶葉に当たり、直火に近い加熱とすることができ、熱効率が向上する。また、熱が処理ドラム内に入ることにより、所定温度に加熱処理される茶葉から蒸発する水分は、この熱の加熱位置との温度差により上昇気流を発生することになり、排出効果を利用して機外へ換気することができるので、換気ファンが不要になり、換気死角がなく、効率が高く、製品品質も向上する。貴重なエネルギーを節約することで、地球温暖化を防止することにもつながり、軽量化も図られる。構造が簡略化され、コストがかからず、安価で、省エネ効果の高い製品を提供する。   According to the apparatus of the present invention, the heat of the heat source directly hits the tea leaves in the processing drum, so that the heating can be made close to an open fire, and the thermal efficiency is improved. In addition, moisture that evaporates from the tea leaves that are heat-treated to a predetermined temperature due to heat entering the processing drum generates an upward airflow due to a temperature difference from the heating position of this heat, and uses the discharge effect. This makes it possible to ventilate outside the machine, eliminating the need for a ventilation fan, eliminating blind spots, increasing efficiency, and improving product quality. Saving valuable energy will help prevent global warming and reduce weight. Provide a product with simplified structure, low cost, low cost and high energy saving effect.

本発明の茶葉焙煎機について、説明する。円筒形の処理ドラム１は一方を茶葉投入口２、他方を茶葉排出口３としており、この処理ドラム１の少なくとも一部を通気性部材で構成している。図２においては処理ドラムの一部が通気性部材であり、図５においては略全部が通気性部材である。通気性部材は、本実施例では金網４を用いているが、金網の他にも耐熱温度が高い合成樹脂のネット、パンチングメタルなど、茶葉が落ちない大きさの開孔で、耐熱温度が高く、加熱により変形や変質をしない部材であればよい。スプロケット６やチェーン７を用いてモータ５の出力によりコロ８を回転させ、そのコロ８を介して処理ドラム１を回転させる。処理ドラム１の内部には茶葉を拡散するための茶葉拡散突起９が備えられており、本実施例では処理ドラム１の前半（９Ａ）と後半（９Ｂ）で茶葉拡散突起９の取付位置をずらしている。熱源は、処理ドラム１の外側に設置してあり、本実施例では電熱ヒータ１０を利用しているが、処理ドラム１の外周を均一に加熱していくことができれば、ガスバーナなどでもよい。   The tea leaf roasting machine of the present invention will be described. One of the cylindrical processing drums 1 is a tea leaf inlet 2 and the other is a tea leaf outlet 3, and at least a part of the processing drum 1 is formed of a breathable member. In FIG. 2, a part of the processing drum is a breathable member, and in FIG. As the air-permeable member, a metal mesh 4 is used in this embodiment, but in addition to the metal mesh, a synthetic resin net having a high heat resistance temperature, a punching metal, etc. are used for opening the tea leaves so that the heat resistance temperature is high. Any member that is not deformed or altered by heating may be used. The roller 8 is rotated by the output of the motor 5 using the sprocket 6 or the chain 7, and the processing drum 1 is rotated through the roller 8. The processing drum 1 is provided with a tea leaf diffusion protrusion 9 for diffusing tea leaves. In this embodiment, the mounting position of the tea leaf diffusion protrusion 9 is shifted between the first half (9A) and the second half (9B) of the processing drum 1. ing. The heat source is installed outside the processing drum 1 and uses the electric heater 10 in this embodiment. However, a gas burner or the like may be used as long as the outer periphery of the processing drum 1 can be heated uniformly.

本実施例では処理ドラム１の外周で熱源の影響を直接受けない場所に、温度計測手段を設ける。本実施例では放射温度計１１を設けているが、他のタイプの温度計測手段でもよく、また作業者が熟練者であれば温度計測手段を設けなくてもよい。   In this embodiment, a temperature measuring means is provided at a place where the influence of the heat source is not directly received on the outer periphery of the processing drum 1. Although the radiation thermometer 11 is provided in the present embodiment, other types of temperature measuring means may be used, and if the operator is an expert, the temperature measuring means may not be provided.

本実施例では、処理ドラム１、コロ８、スプロケット６、モータ５、電熱ヒータ１０などを支持する機体枠１２に角度調節手段を設ける。一端側に角度調節軸１３を設け、他端側に角度調節レバー１４を設け、この角度調節レバー１４を上下することで、角度調節軸１３を中心として、処理ドラム１を傾斜させる。角度調節レバー１４を一番上にすると処理ドラム１が水平になり、角度調節レバー１４を徐々に下げると、茶葉排出口３側が徐々に下がる。本実施例では、連続して茶葉を投入して、連続して茶葉を取り出すために、処理ドラム１の傾斜が必要であるが、処理ドラム１の傾斜が不要であれば、角度調節手段は不要である。   In this embodiment, an angle adjusting means is provided on the machine body frame 12 that supports the processing drum 1, the roller 8, the sprocket 6, the motor 5, the electric heater 10, and the like. An angle adjusting shaft 13 is provided on one end side, an angle adjusting lever 14 is provided on the other end side, and the processing drum 1 is tilted about the angle adjusting shaft 13 by moving the angle adjusting lever 14 up and down. When the angle adjustment lever 14 is at the top, the processing drum 1 becomes horizontal, and when the angle adjustment lever 14 is gradually lowered, the tea leaf discharge port 3 side is gradually lowered. In this embodiment, in order to continuously input tea leaves and continuously take out tea leaves, it is necessary to incline the processing drum 1. However, if the inclination of the processing drum 1 is not required, the angle adjusting means is not required. It is.

処理ドラム１の茶葉投入口２へ茶葉２０を投入しやすいよう、茶葉投入シュート２１を設ける。本実施例では、この茶葉投入シュート２１の上方に定量供給装置としてスクリューコンベヤ２２を設ける。茶葉を定量的に供給することができれば、スクリューコンベヤ２２ではなく、トラフコンベヤ、ベルトコンベヤなどの他の搬送装置でもよく、また、装置ではなく、作業者が定量的に供給してもよい。本実施例のスクリューコンベヤ２２の場合、モータ２４によってスクリュー２３を回転させ、ストックホッパ２５内の茶葉を搬送していく。このスクリューコンベヤ２２は上部にカバー２６をしており、処理ドラム１の上方にあるために、熱がこもりやすいため、換気ファン２７を取り付け、スクリューコンベヤ２２２５内の換気をよくしている。ここで熱がこもり、換気が行われない場合は、ストックホッパ２５内の投入待機中の茶葉が変質してしまう恐れがある。   A tea leaf feeding chute 21 is provided so that the tea leaf 20 can be easily fed into the tea leaf inlet 2 of the processing drum 1. In the present embodiment, a screw conveyor 22 is provided above the tea leaf charging chute 21 as a quantitative supply device. As long as tea leaves can be supplied quantitatively, other conveying devices such as a trough conveyor and a belt conveyor may be used instead of the screw conveyor 22, and the operator may supply quantitatively instead of the device. In the case of the screw conveyor 22 of the present embodiment, the screw 23 is rotated by the motor 24 and the tea leaves in the stock hopper 25 are conveyed. Since this screw conveyor 22 has a cover 26 at the top and is above the processing drum 1, heat is easily trapped, so a ventilation fan 27 is attached to improve the ventilation inside the screw conveyor 2225. Here, when heat is accumulated and ventilation is not performed, there is a possibility that the tea leaves in the stock hopper 25 that are waiting to be put in are deteriorated.

茶葉排出口３側には、排気筒３１を設ける。排気筒３１の下部は茶葉２０を取り出すための茶葉取出シュート３２になっている。排気筒３１の上部にはシャッタ３３が備えられており、加熱中には熱の排出を防ぐためにシャッタ３３を閉じ、排気時にはシャッタ３３を開けることにより、排気筒３１の上から蒸発した水分を含んだ空気を排気することができる。茶葉取出シュート３２から取り出された茶葉は、容器３４へ入れられる。   An exhaust pipe 31 is provided on the tea leaf outlet 3 side. A lower portion of the exhaust cylinder 31 is a tea leaf takeout chute 32 for taking out the tea leaf 20. A shutter 33 is provided in the upper part of the exhaust cylinder 31. The shutter 33 is closed during heating to prevent the heat from being exhausted, and when the exhaust is exhausted, the shutter 33 is opened to contain moisture evaporated from above the exhaust cylinder 31. The air can be exhausted. The tea leaves taken out from the tea leaf takeout chute 32 are put into a container 34.

処理ドラム１、コロ８、スプロケット６、モータ５、電熱ヒータ１０などを支持している機体枠１２には保温カバー１５を備え、更にこの保温カバー１５の外面または内面に断熱材１６を取り付け、外側の機体枠１７には熱が伝わりにくいよう、安全性を保っている。   The body frame 12 supporting the processing drum 1, the roller 8, the sprocket 6, the motor 5, the electric heater 10 and the like is provided with a heat insulating cover 15, and a heat insulating material 16 is attached to the outer surface or the inner surface of the heat insulating cover 15, The body frame 17 is kept safe so that heat is not easily transmitted.

上記のような装置を起動した場合の動きを説明する。ブレーカスイッチ４１を操作してブレーカを入れ、処理ドラムスイッチ４２を操作して処理ドラム１のモータ５の電源を入れることで、モータ５が回転し、処理ドラム１が回転する。次に、熱源である電熱ヒータスイッチ４３を操作して電熱ヒータ１０の電源を入れ、電熱ヒータ１０により処理ドラム１を均一に加熱していく。このとき、排気筒３１のシャッタ３３は閉じ、熱の排出を防ぐ。電熱ヒータ１０の熱は、周囲の空気温度の上昇から浮力を得て、金網４から処理ドラム１内に入っていく。放射温度計１１により処理ドラム１の周囲の温度を計測しながら所定温度まで加熱する。処理ドラム１が所定温度に達した場合、スクリューコンベヤスイッチ４４を操作してスクリューコンベヤ２２のモータ２４の電源を入れ、モータ２４を回転させ、スクリュー２３を回転させ、ストックホッパ２５にためた茶葉を定量的に茶葉投入シュート２１へ供給する。そして、茶葉を茶葉投入口２より定量的に処理ドラム１へ供給する。   The operation when the above apparatus is activated will be described. By operating the breaker switch 41 to turn on the breaker and operating the processing drum switch 42 to turn on the motor 5 of the processing drum 1, the motor 5 rotates and the processing drum 1 rotates. Next, the electric heater switch 43 as a heat source is operated to turn on the electric heater 10, and the processing drum 1 is uniformly heated by the electric heater 10. At this time, the shutter 33 of the exhaust cylinder 31 is closed to prevent heat from being discharged. The heat of the electric heater 10 gains buoyancy from the rise in ambient air temperature and enters the processing drum 1 from the wire mesh 4. The radiation thermometer 11 is heated to a predetermined temperature while measuring the temperature around the processing drum 1. When the processing drum 1 reaches a predetermined temperature, the screw conveyor switch 44 is operated to turn on the motor 24 of the screw conveyor 22, the motor 24 is rotated, the screw 23 is rotated, and the tea leaves accumulated in the stock hopper 25 are removed. The tea leaves are quantitatively supplied to the chute 21. Then, the tea leaves are quantitatively supplied to the processing drum 1 from the tea leaf inlet 2.

処理ドラム１内へ投入された茶葉は、電熱ヒータ１０からの熱を効率よく受け、茶葉拡散突起９により拡散されながら水分を放出しつつ、所定の焙煎度合いに加熱処理される。蒸発した水分を含む空気は、金網４から保温カバー１５との空間を通過、あるいは処理ドラム１内の処理中の茶葉との空間を通過し、シャッタ３３の開き度によって排気筒３１から排気される。このように、温度差と位置的ドラフト効果により機外に排出される場合、水分の排出が効果的に行なわれ、いわゆる水分によるムレを防ぎ、すっきりとした香気と味に仕上がる。そして、処理ドラム１内で焙煎された茶葉は、茶葉排出口３から取り出され、容器３４内へ収容される。   The tea leaves put into the processing drum 1 receive heat from the electric heater 10 efficiently and are heated to a predetermined roasting degree while releasing moisture while being diffused by the tea leaf diffusion protrusions 9. The air containing the evaporated water passes through the space between the wire mesh 4 and the heat insulating cover 15 or passes through the space between the processing drum 1 and the tea leaf being processed, and is exhausted from the exhaust cylinder 31 depending on the degree of opening of the shutter 33. . In this way, when discharged to the outside due to the temperature difference and the positional draft effect, moisture is effectively discharged, so-called stuffiness due to moisture is prevented, and a clean aroma and taste are achieved. Then, the tea leaves roasted in the processing drum 1 are taken out from the tea leaf discharge port 3 and accommodated in the container 34.

茶葉の焙煎度合いは、茶葉の投入量を増やしたり、減じたりすることにより、処理ドラム１を通過する茶葉の通過時間を調節する。あるいは、茶葉投入量は一定に保持したまま、処理ドラム１の傾斜角度を調節することにより通過時間の調節をする。この時、処理ドラム１が略水平な状態から茶葉排出口３が約７度下がる程度まで調節する。通常、煎茶の火入れ程度であれば、茶葉温度が１００度前後になるように処理ドラム１を加熱し、通過時間を調整しながら火入れ具合を所望するよう調節するが、ほうじ茶の場合は、処理ドラム１を２５０度前後まで加熱し、茶葉から煙が出る程度まで加熱処理する。   The degree of roasting of the tea leaves adjusts the passage time of the tea leaves that pass through the processing drum 1 by increasing or decreasing the input amount of the tea leaves. Alternatively, the passage time is adjusted by adjusting the inclination angle of the processing drum 1 while keeping the tea leaf input amount constant. At this time, the processing drum 1 is adjusted from a substantially horizontal state until the tea leaf outlet 3 is lowered by about 7 degrees. Normally, if it is about the temperature of sencha, the processing drum 1 is heated so that the tea leaf temperature is around 100 degrees and adjusted to the desired condition while adjusting the passage time. 1 is heated to around 250 ° C. and heat-treated until smoke comes out from the tea leaves.

次に、茶葉を連続的に処理しない場合を説明する。この場合、定量供給装置や傾斜角度調節手段は不要である。ある程度の量の茶葉を茶葉投入シュート２１により処理ドラム１へ投入し、所望の焙煎度合いになるまで加熱する。所望の焙煎度合いになったら、処理ドラム１内の茶葉すべてを茶葉排出口３から取り出す。   Next, a case where tea leaves are not processed continuously will be described. In this case, a fixed amount supply device and an inclination angle adjusting means are unnecessary. A certain amount of tea leaves are put into the processing drum 1 by the tea leaf feeding chute 21 and heated until a desired roasting degree is reached. When the desired roasting degree is reached, all the tea leaves in the processing drum 1 are taken out from the tea leaf outlet 3.
