Description

本発明は、茶葉を無端輸送帯上にて乾燥する製茶乾燥機に関するものである。   The present invention relates to a tea dryer that dries tea leaves on an endless transport zone.

従来の一般的な製茶法で用いる製茶乾燥機は、水分が少ない茶葉（１０〜１５％Ｄ．Ｂ．）を乾燥する。この場合、特許文献１に記載されているように、製茶乾燥機の１段目に投入するところへ撹拌装置（逆転）を設ければ、無端輸送帯の上へ茶葉が薄く広がる。茶葉の水分が少ないため、茶葉と茶葉がくっついてしまうことはない。２段目、３段目の無端輸送帯へ落下するときにも、茶葉が重なることなくそのまま薄く広がる。   A tea dryer used in a conventional general tea manufacturing method dries tea leaves (10 to 15% DB) with low water content. In this case, as described in Patent Document 1, if a stirring device (reverse rotation) is provided at the first stage of the tea dryer, the tea leaves spread thinly over the endless transport zone. Tea leaves and tea leaves do not stick together because of the low water content of tea leaves. Even when falling to the second and third stage endless transport zones, the tea leaves spread thinly without overlapping.

近年、製茶法が多様になり、水分が多い茶葉（８０％Ｄ．Ｂ．以上）を乾燥することがある。水分が多い茶葉は、水分が少ない時と比べて、茶葉と茶葉が重なり、塊となってしまう。塊になると、茶葉の塊の表面だけが乾燥し、内側が乾燥しない。無端輸送帯の２段目、３段目へ落下するときに、塊がほぐれたとしても、同じ位置に落下するため、無端輸送帯上では重なり、塊の時と同様に、表面だけが乾燥し、内側が乾燥しない。   In recent years, tea manufacturing methods have been diversified, and tea leaves with a high water content (80% DB or more) may be dried. The tea leaves with a lot of moisture are overlapped with each other and become a lump compared to when the moisture is low. When it becomes a lump, only the surface of the lump of tea leaves is dried and the inside is not dried. Even if the lump is loosened when falling to the 2nd or 3rd stage of the endless transport zone, it falls to the same position, so it overlaps on the endless transport zone and only the surface dries like the lump. , The inside does not dry.

このような状況が続くと、いつまでも茶葉の内側が乾燥せず、茶葉の色を落とす原因となり、処理能力が下がってしまうという問題があった。   If such a situation continues, the inside of the tea leaves will not dry forever, causing the color of the tea leaves to drop, resulting in a decrease in processing capacity.

乾燥室２へ茶葉を定量ずつ供給するために給葉機２１を設ける。前の工程から搬送された茶葉は給葉機２１へ入れられ、給葉機２１に設けたかきならし装置２２で茶葉がならされ、投入シュート２３を通って乾燥室２へ供給される。乾燥室２で乾燥が終了した茶葉は、取出部に設けたロータリーバルブ１１により取出コンベヤ２６上へ取り出され、次の工程へ搬送される。   A leaf feeder 21 is provided to supply tea leaves to the drying chamber 2 in a fixed amount. The tea leaves transported from the previous process are put into the leaf feeder 21, tea leaves are smoothed by the straining device 22 provided in the leaf feeder 21, and supplied to the drying chamber 2 through the charging chute 23. The tea leaves that have been dried in the drying chamber 2 are taken out onto the take-out conveyor 26 by the rotary valve 11 provided in the take-out section, and conveyed to the next step.

乾燥室２の底面の多孔板３は茶葉の進行方向に対して平行の長孔となっている。この長孔を熱風が通り抜ける。この多孔板３の上には、多孔板３上を移動する仕切板７を設ける。一対のスプロケット１０の間を張られた無端帯６にこの仕切板７の軸が取り付けられており、多孔板３上では仕切板７がほぼ垂直となり、多孔板３と仕切板７は接触しない程度に接近して設けられている。   The perforated plate 3 on the bottom surface of the drying chamber 2 is a long hole parallel to the traveling direction of the tea leaves. Hot air passes through this long hole. A partition plate 7 that moves on the porous plate 3 is provided on the porous plate 3. A shaft of the partition plate 7 is attached to an endless belt 6 stretched between a pair of sprockets 10. The partition plate 7 is almost vertical on the porous plate 3, and the porous plate 3 and the partition plate 7 are not in contact with each other. It is provided close to.

この無端帯６の上面では仕切板７が水平に配置されるような構造となっており、茶葉をのせて搬送することができる無端輸送帯１７Ｃとなる。仕切板７に複数の孔を開孔することで、無端輸送帯１７Ｃは通気性となり、無端輸送帯１７Ｃ上で茶葉を乾燥することができる。本実施例では、上段に更に１組の無端輸送帯１７を設ける。この無端輸送帯１７は上面、下面共に無端輸送帯１７Ａ、１７Ｂとなっており、下段の無端輸送帯１７Ｃや多孔板３を通過した多量の熱風を再利用し、予備乾燥とすることができる。本実施例では、１〜３段目の無端輸送帯１７Ａ、１７Ｂ、１７Ｃが静置式乾燥部、４段目の多孔板３が流動層乾燥部となる。   On the upper surface of the endless belt 6, the partition plate 7 is structured to be horizontally arranged, and an endless transport belt 17 </ b> C capable of carrying tea leaves is provided. By opening a plurality of holes in the partition plate 7, the endless transport zone 17C becomes air permeable and the tea leaves can be dried on the endless transport zone 17C. In this embodiment, a pair of endless transport zones 17 are further provided on the upper stage. The endless transport zone 17 has endless transport zones 17A and 17B on the upper and lower surfaces, and a large amount of hot air that has passed through the lower endless transport zone 17C and the perforated plate 3 can be reused for preliminary drying. In this embodiment, the first to third stage endless transport zones 17A, 17B, and 17C serve as a stationary drying unit, and the fourth stage perforated plate 3 serves as a fluidized bed drying unit.

本実施例では、２段目の無端輸送帯１７Ｂ上に、まず正転の撹拌装置３１を設け、次に逆転の撹拌装置３６を設ける。正転の撹拌装置３１は撹拌軸３４と撹拌羽根３５がほぼ接触しているが、逆転の撹拌装置３６は撹拌軸３９と撹拌羽根４０との間に空間を設けるように取り付けてある。正転の撹拌装置３１により茶葉を送り込み、逆転の撹拌装置３６により茶葉を戻すことで、撹拌装置３１と撹拌装置３６との間で、茶葉は撹拌されて塊はほぐされ、無端輸送帯１７Ｂと撹拌羽根４０との間を通る茶葉のみ均一な高さで進んでいく。大きくて通れない茶葉は、撹拌羽根４０によって戻され、再び撹拌される。撹拌装置３１、３６はそれぞれ高さ調整機構３３、３８を設け、それぞれの高さを調整している。本実施例では、製茶乾燥機１に固定した取付具１８と撹拌装置３１、３６とをネジ３３Ａ、３８Ａで接続し、ネジ３３Ａ、３８Ａを回すことで高さを調整する。本実施例では、２段目の無端輸送帯１７Ｂ上に撹拌装置３１、３６を設けたが、２段目ではなく３段目、または２段目と３段目の両方に設けてもよい。また、１段目の途中〜後半に設けてもよい。また、無端輸送帯１７の本数によってはこの限りではない。   In the present embodiment, the forward stirring device 31 is first provided on the second endless transport zone 17B, and then the reverse stirring device 36 is provided. The forward stirring device 31 is substantially in contact with the stirring shaft 34 and the stirring blade 35, but the reverse stirring device 36 is attached so as to provide a space between the stirring shaft 39 and the stirring blade 40. By feeding the tea leaves with the forward stirring device 31 and returning the tea leaves with the reverse stirring device 36, the tea leaves are stirred and the lump is loosened between the stirring device 31 and the stirring device 36, and the endless transport zone 17B Only the tea leaves passing between the stirring blades 40 proceed at a uniform height. Tea leaves that are too large to pass through are returned by the stirring blade 40 and stirred again. The stirrers 31 and 36 are provided with height adjusting mechanisms 33 and 38, respectively, to adjust the respective heights. In the present embodiment, the fixture 18 fixed to the tea dryer 1 and the stirring devices 31 and 36 are connected by screws 33A and 38A, and the height is adjusted by turning the screws 33A and 38A. In the present embodiment, the stirring devices 31 and 36 are provided on the second-stage endless transport zone 17B, but they may be provided not on the second stage but on the third stage, or both the second and third stages. Further, it may be provided in the middle to the latter half of the first stage. Further, this is not limited depending on the number of endless transport zones 17.

本実施例では、多孔板３には茶葉Ｔの進行方向に対して平行のφ１×２０の長孔を１０ミリピッチで開いている。長孔が大きすぎると茶葉Ｔが長孔から落下し、長孔が小さすぎると透気量が減って、茶葉Ｔが浮遊しないので乾燥しない。茶葉Ｔが落下せず、茶葉Ｔが浮遊して乾燥する大きさを選定するとよい。また、単なる丸形状にすると茶葉の茎が孔に刺さるので、単なる丸形状より長形状にすることで、茶葉Ｔの浮遊が良好である。   In this embodiment, φ1 × 20 long holes parallel to the traveling direction of the tea leaves T are opened in the perforated plate 3 at a pitch of 10 mm. If the long hole is too large, the tea leaf T falls from the long hole, and if the long hole is too small, the air permeability decreases and the tea leaf T does not float and does not dry. It is preferable to select a size at which the tea leaves T do not fall and the tea leaves T float and dry. Moreover, since the stem of a tea leaf will pierce a hole if it is made into a simple round shape, the floating of the tea leaf T will be favorable by making it into a shape longer than a simple round shape.

多孔板３上の仕切板７は軸により無端帯６に軸着されており、略垂直に配置されている。これにより、多孔板３を通過した熱風は仕切板７に沿って多孔板３上を通過する。また、仕切板７は熱風により浮遊中の茶葉を始端側（図１においては右）から終端側（図１においては左）へ押し、進行方向を誘導する機能も有する。   The partition plate 7 on the perforated plate 3 is pivotally attached to the endless belt 6 by a shaft, and is arranged substantially vertically. Thereby, the hot air that has passed through the porous plate 3 passes along the partition plate 7 over the porous plate 3. The partition plate 7 also has a function of pushing the tea leaves that are floating with hot air from the start side (right in FIG. 1) to the end side (left in FIG. 1) to guide the traveling direction.

茶葉を給葉機２１に投入すると、かきならし装置２２により幅全体に広げられ、乾燥室２へ投入する。無端輸送帯１７Ａ上では下方からの熱風により乾燥される。水分が多い茶葉（８０％Ｄ．Ｂ．以上）の場合、茶葉が塊のまま搬送され、塊の表面のみ熱風により乾燥される。１段目の無端輸送帯１７Ａの終端（図１においては乾燥室２の右端）で２段目の無端輸送帯１７Ｂへ茶葉Ｔを落下させ、２段目の無端輸送帯１７Ｂでも同様に搬送しながら乾燥する。この時、茶葉Ｔの塊は表面が乾燥しても塊のまま落下する。表面のみ乾燥し、内側は水分が多いままである。この茶葉Ｔの塊を撹拌羽根３５により撹拌装置３１の先へ送り込む。この時茶葉Ｔの塊に撹拌羽根３５が当たることで、茶葉Ｔの塊はほぐれる。撹拌装置３６の撹拌羽根４０により茶葉Ｔを撹拌装置３１へ向けて戻す。撹拌羽根３５と撹拌羽根４０の両方で撹拌されることで茶葉Ｔの塊はほぐれ、撹拌羽根４０と無端輸送帯１７Ｂとの間より小さくなった茶葉Ｔが搬送されていく。この時、撹拌装置３１、３６の高さは、搬送時間、搬送速度、搬送量、茶葉Ｔの水分量などにより調整するが、撹拌装置３１と撹拌装置３６との間に茶葉Ｔがいっぱいになってしまった場合、撹拌装置３６の撹拌軸３９と撹拌羽根４０の間から茶葉Ｔをオーバーフローさせる。ほぐれた茶葉Ｔは無端輸送帯１７Ｂ上で乾燥され、搬送される。   When the tea leaves are put into the feeder 21, the tea leaves are spread over the entire width by the stirring device 22 and put into the drying chamber 2. It is dried on the endless transport zone 17A by hot air from below. In the case of tea leaves with a high water content (80% DB or more), the tea leaves are transported as a lump, and only the surface of the lump is dried with hot air. At the end of the first stage endless transport zone 17A (the right end of the drying chamber 2 in FIG. 1), the tea leaves T are dropped to the second stage endless transport zone 17B, and are transported in the same manner in the second stage endless transport zone 17B. Dry while. At this time, the lump of tea leaves T falls as a lump even if the surface is dried. Only the surface is dry and the inside remains moist. The lump of tea leaves T is sent to the tip of the stirring device 31 by the stirring blade 35. At this time, when the stirring blade 35 hits the lump of tea leaves T, the lump of tea leaves T is loosened. The tea leaves T are returned toward the stirring device 31 by the stirring blade 40 of the stirring device 36. By stirring with both the stirring blade 35 and the stirring blade 40, the lump of the tea leaf T is loosened, and the tea leaf T that is smaller than between the stirring blade 40 and the endless transport zone 17B is conveyed. At this time, the height of the stirring devices 31 and 36 is adjusted by the transport time, the transport speed, the transport amount, the moisture content of the tea leaf T, etc., but the tea leaf T is filled between the stirring device 31 and the stirring device 36. If this happens, the tea leaves T are caused to overflow from between the stirring shaft 39 and the stirring blade 40 of the stirring device 36. The loose tea leaves T are dried and transported on the endless transport zone 17B.

２段目の無端輸送帯１７Ｂの終端（図１においては乾燥室２の左端）で３段目の無端輸送帯１７Ｃへ茶葉を落下させ、３段目の無端輸送帯１７Ｃでも同様に搬送しながら乾燥する。３段目の無端輸送帯１７Ｃの終端（図１においては乾燥室２の右端）で多孔板３上へ落下させ、多孔板３上では茶葉を浮遊させ、熱風を少し進行方向へ向けて供給し、仕切板７にて押しながら、乾燥する。多孔板３上では大きく浮遊することで、乾燥効率がよくなる。多孔板３上で乾燥した茶葉Ｔは取出部（図１においては乾燥室２の左端）のロータリーバルブ１１から取出コンベヤ２６へ取り出される。   Tea leaves are dropped onto the third endless transport zone 17C at the end of the second endless transport zone 17B (the left end of the drying chamber 2 in FIG. 1), and the third stage endless transport zone 17C is transported in the same manner. dry. Dropped onto the perforated plate 3 at the end of the third-stage endless transport zone 17C (the right end of the drying chamber 2 in FIG. 1), floats the tea leaves on the perforated plate 3, and supplies hot air slightly in the direction of travel. Then, press the partition plate 7 to dry it. A large floating on the perforated plate 3 improves the drying efficiency. The tea leaves T dried on the perforated plate 3 are taken out from the rotary valve 11 of the takeout part (the left end of the drying chamber 2 in FIG. 1) to the takeout conveyor 26.

熱風発生装置４では、静置式の製茶乾燥機の約３〜７倍程度の熱風を発生させて供給する。本実施例の装置へ約２２０％Ｄ．Ｂ．の茶葉を投入すると、投入から取出まで３４分間乾燥し、約３％Ｄ．Ｂ．の茶葉が取り出される。投入する茶葉の水分が少なければ、熱風の供給量を減らしたり、乾燥時間を短くしたりすることができる。   The hot air generator 4 generates and supplies hot air about 3 to 7 times that of a stationary tea-making dryer. About 220% D.V. B. When the tea leaves are added, they are dried for 34 minutes from the input to the extraction, and about 3% D.D. B. Tea leaves are taken out. If the water content of the tea leaves to be introduced is small, the amount of hot air supplied can be reduced or the drying time can be shortened.

多量の熱風を供給するため、供給した量の熱風を排気することができる排気手段５が必要である。   In order to supply a large amount of hot air, the exhaust means 5 that can exhaust the supplied amount of hot air is required.

茶葉が大きいと乾燥しにくいため、製茶乾燥機１へ投入する前に、茶葉を小さく加工することもある。例えば、紅茶の加工によく使用されるＣＴＣ加工機などにより茶葉を小さくする。   Since the tea leaves are difficult to dry if they are large, the tea leaves may be processed smaller before being put into the tea dryer 1. For example, the tea leaves are reduced by a CTC processing machine often used for processing black tea.

製茶乾燥機１の他の実施例として、乾燥室２のすべてが無端輸送帯１７による静置乾燥部であるものを図６に示す。無端輸送帯１７上の適宜な場所に、撹拌装置３１と撹拌装置３６を設ける。   FIG. 6 shows another example of the tea dryer 1 in which the drying chamber 2 is a stationary drying unit with an endless transport zone 17. A stirrer 31 and a stirrer 36 are provided at appropriate locations on the endless transport zone 17.

本発明の無端輸送帯１７は、例えば、複数の多孔板によるものやネットによるもの等がある。本発明のような構成で、茶葉の水分を下げることができるようなものであれば、本発明の製茶乾燥機に含まれる。   The endless transport zone 17 of the present invention includes, for example, a plurality of perforated plates and a net. Any tea-drying machine according to the present invention can be used as long as it can reduce the water content of the tea leaves.
