Description

本発明は、荒茶を製造する固定胴型製茶機の熱風発生器に関するものである。   TECHNICAL FIELD The present invention relates to a hot air generator of a fixed barrel type tea making machine for producing rough tea.

製茶ラインは、おおまかに、蒸機、粗揉機、揉捻機、中揉機、精揉機、乾燥機などの製茶機によって構成されている。蒸機により蒸熱された茶葉は、良質な荒茶ができるよう、粗揉機以降の製茶機により適正な速度で乾燥される。そのために、製茶中には、様々な熱風供給の制御が行なわれている（例えば、特許文献１）。通常、加熱乾燥手段としては、粗揉機および中揉機、乾燥機では熱風乾燥、精揉機では伝熱乾燥が行われている。きわめて水分の高い茶生葉（約４００％Ｄ．Ｂ．）からほぼ絶乾状態の茶（約５％Ｄ．Ｂ．）まで乾燥させるため、使用する熱エネルギーは非常に大きい。   The tea making line is roughly composed of tea making machines such as a steamer, a rough kneading machine, a kneading machine, a middle kneading machine, a kneading machine, and a dryer. The tea leaves steamed by the steamer are dried at an appropriate speed by a tea making machine after the rough kneader so that high quality rough tea can be produced. Therefore, various control of hot air supply is performed during tea making (for example, Patent Document 1). Usually, as a heating and drying means, a rough kneader and a middle kneader, a dryer and hot air drying, and a fine kneader are heat transfer drying. The heat energy used is very large because it is used to dry tea leaves with extremely high water content (about 400% DB) to almost dry tea (about 5% DB).

一般的に朝から夕方に茶生葉の摘採を行ない、製茶工場ではそれに合わせて茶生葉の受入を行ない、昼過ぎから翌日の朝にかけて製茶を行なう。製茶の準備のため、昼頃に製茶機の電源を入れると、翌日の朝に終了するまで製茶機の電源を切らず、入れっぱなしになる。つまり、茶葉が投入される前に、製茶機を温めて、準備を完了していなければならず、早めに電源を入れておく。   In general, fresh tea leaves are plucked from morning to evening, and fresh tea leaves are accepted at tea factories accordingly, and tea is made from early afternoon to the next morning. If you turn on the tea making machine around noon to prepare for tea making, the tea making machine will not be turned off and will be left on until the end of the next morning. That is, the tea making machine must be warmed up and ready before the tea leaves are put in, and the power is turned on early.

茶葉が投入されている製茶機は、製茶に最適な熱風の温度と風量が制御され、茶葉が排出されたあとの空の製茶機は、次の茶葉の投入に備えて投入時の設定値になるように熱風の温度と風量が制御されている。各製茶機の時間はスムーズに製茶が行なわれるように設定してあり、茶葉の水分を基に制御している場合は、茶葉の水分等の状態により設定時間より早く排出されることがある。また、製茶ラインは茶葉が滞留すると困るため、少し余裕を持って配置してある。よって、常時、全ての製茶機に茶葉が入って製茶しているとは限らず、次の茶葉が投入されるのを待機している空の製茶機が存在する。この時も、製茶機は熱風の温度と風量を投入時の設定値になるように制御し、バーナを燃焼しており、常に大きな熱エネルギーが使用されていた。   The tea making machine that supplies tea leaves controls the temperature and volume of the hot air that is optimal for making tea, and the empty tea making machine after the tea leaves are discharged is set to the set value at the time of preparation for the next tea making. The temperature and volume of hot air are controlled so that The time of each tea making machine is set so that tea can be smoothly produced, and when it is controlled based on the water content of the tea leaves, it may be discharged earlier than the set time depending on the water content of the tea leaves. In addition, the tea-making line is arranged with a little extra space because it is difficult for the tea leaves to accumulate. Therefore, not all tea making machines always contain tea leaves and make tea, and there are empty tea making machines waiting for the next tea leaves to be introduced. At this time as well, the tea making machine controlled the temperature and volume of the hot air to the set values at the time of introduction, burned the burner, and always used a large amount of heat energy.

そのため、省エネルギー化を図ろうと、近年、特許文献２のような製茶機が発明されていた。   Therefore, in order to save energy, a tea making machine as disclosed in Patent Document 2 has been invented in recent years.

特開昭６０−７５２３５号公報JP-A-60-75235 特開２０１２−３４５９０号公報JP, 2012-34590, A

特許文献２の固定胴型製茶機の熱風発生器は熱交換をするタイプのものであり、空気をあたためるためには時間がかかった。そのため、茶葉を投入するよりも前にバーナを起動させなければならず、また、バーナを停止した後も熱風発生器内が熱く、送風ファンを停止させることはできない等の、問題をかかえていた。   The hot air generator of the fixed-body type tea making machine of Patent Document 2 is of a type that performs heat exchange, and it took time to warm the air. Therefore, the burner had to be started before the tea leaves were fed, and even after the burner was stopped, the inside of the hot air generator was hot and the blower fan could not be stopped. .

本発明は、このような問題を解決し、一層、燃料や電気の使用を削減することを課題としている。   An object of the present invention is to solve such a problem and further reduce the use of fuel and electricity.

本発明の第１手段は、固定胴型製茶機において、送風ファンによる空気の送風経路にバーナを設けて、該バーナで直接加熱した熱風を前記送風ファンで送風して、乾燥室内へ供給することを特徴とする固定胴型製茶機の熱風発生器。
本発明の第２手段は、前記第１手段において、前記バーナの燃料はガスとする。
本発明の第３手段は、前記第１または２手段において、前記熱風の温度を測定し、あらかじめ設定した温度になるようにバーナの燃焼量を比例制御する。
本発明の第４手段は、前記第１、２または３手段において、前記乾燥室から茶葉を取り出したときに前記バーナを停止させ、前記乾燥室へ茶葉を投入したときに前記バーナを燃焼させる。
本発明の第５手段は、前記第４手段において、前記バーナの燃焼とともに、前記送風ファンを設定風量にし、前記バーナの停止とともに、前記送風ファンを最低風量または停止する。
本発明の第６手段は、前記第４手段において、前記バーナの燃焼とともに、前記送風ファンを設定風量にし、前記バーナの停止時には、あらかじめ定めた時間の後に前記送風ファンを最低風量または停止する。 A first means of the present invention is, in a fixed-body type tea making machine, a burner is provided in an air blowing path of a blower fan, and hot air directly heated by the burner is blown by the blower fan to be supplied into a drying chamber. A hot-air generator for a fixed-body type tea making machine.
According to a second aspect of the present invention, in the first aspect, the fuel of the burner is gas.
In a third means of the present invention, in the first or second means, the temperature of the hot air is measured and the burner combustion amount is proportionally controlled so as to reach a preset temperature.

According to a sixth aspect of the present invention, in the fourth means, the blower fan is set to a set airflow rate along with the combustion of the burner, and when the burner is stopped, the blower fan is stopped at the minimum airflow rate or stopped after a predetermined time.

本発明の第１、２、３手段により、熱交換することなく熱風を供給するので、燃料の消費を抑えることができ、第３手段により、安定した熱風を供給できる。本発明の第４、５、６手段により、固定胴型製茶機へ供給することが必要な時のみ熱風を発生させるため、燃料の消費を抑えることができる。第６手段により、熱風発生器の熱を送風ファンの送風により取り除くので、熱風発生器の損傷を防ぐことができる。   By the first, second and third means of the present invention, hot air is supplied without heat exchange, so fuel consumption can be suppressed, and by the third means, stable hot air can be supplied. By the fourth, fifth and sixth means of the present invention, the hot air is generated only when it is necessary to supply the fixed barrel type tea making machine, so that the fuel consumption can be suppressed. By the sixth means, the heat of the hot air generator is removed by the air blow of the blower fan, so that the hot air generator can be prevented from being damaged.

The tea making line is composed of a rough kneading machine 1, a rough kneading machine 2, a kneading machine 3, a middle kneading machine 4, a middle kneading machine 5, a carrier machine 6 and the like (there is a steamer before this, and a fine kneading machine and a drying machine after this). Machine, etc., but not described in this embodiment). The rough kneading machines 1 and 2 are fixed-body type tea making machines. Each of these tea making machines 1 to 5 is provided with a control means (coarse kneading machine control device 1A, 2A, kneading machine control device 3A, middle kneading machine control device 4A, 5A), and controls the operating status. The carrier 6 includes a carrier control device 6A, and controls the plurality of carrier 6 as a whole. A measuring device 7 is installed in front of the rough kneader 1, and the measured value of the measuring device 7 is set by the measuring device control device 7A. These control devices 1A to 7A are connected by a network, and the line control device 8A controls the operating conditions of the control devices 1A to 7A as a whole. FIG. 1 is merely an example of a tea making line, and the types of tea making machines, the number of each tea making machine, and the arrangement are not limited to this.

図２〜５は粗揉機１である。粗揉機１は主に半円筒形の固定胴の乾燥室１１であり、加熱乾燥手段である熱風発生器１６を設ける。本実施例では熱風発生器１６を２セット備えているが、熱風発生器１６の数はこの限りではない。乾燥室１１内には回転する主軸１２に装着した揉手１３、葉浚い手１４を備え、熱風発生器１６にはバーナ１７と送風ファン１８を備えている。乾燥室１１内では、熱風発生器１６による熱風をダクト２０により送風し、茶葉を乾燥する。ダクト２０内に整流板（図示しない）を設けることにより、乾燥室１１へ供給する熱風を調整することができる。熱風発生器１６では、送風ファン１８によって送られた空気を、燃料にガスを用いたバーナ１７により加熱し、この加熱された空気を送風ファン１８により送風し、ダクト２０を通って乾燥室１１内へ供給している。従来、製茶機の燃料には重油を用いることが多かったが、重油の臭いが茶葉へ付着するのを防ぐため、ガスの方が良好である。送風ファン１８にはインバータ（図示しない）が接続されており、風量を無段階に調節できる。乾燥室１１内には温度測定手段（図示しない）を設け、熱風発生器１６により送風される熱風の温度を測っている。熱風の温度が設定した温度になるように、バーナ１７を比例制御する。比例制御でなくてもよいが、比例制御をすることにより熱風の温度が安定する。   2 to 5 show a rough kneader 1. The rough kneader 1 is a semi-cylindrical fixed-cylinder drying chamber 11 and is provided with a hot air generator 16 which is a heating and drying means. In this embodiment, two sets of hot air generators 16 are provided, but the number of hot air generators 16 is not limited to this. The drying chamber 11 is provided with a rubbing hand 13 attached to a rotating main shaft 12 and a dredging hand 14, and a hot air generator 16 is provided with a burner 17 and a blower fan 18. In the drying chamber 11, hot air from the hot air generator 16 is blown through the duct 20 to dry the tea leaves. By providing a current plate (not shown) in the duct 20, the hot air supplied to the drying chamber 11 can be adjusted. In the hot air generator 16, the air sent by the blower fan 18 is heated by the burner 17 using gas as fuel, the heated air is blown by the blower fan 18, and the inside of the drying chamber 11 passes through the duct 20. Supply to. In the past, heavy oil was often used as fuel for tea making machines, but gas is preferable in order to prevent the smell of heavy oil from adhering to tea leaves. An inverter (not shown) is connected to the blower fan 18 so that the air volume can be adjusted steplessly. Temperature measuring means (not shown) is provided in the drying chamber 11 to measure the temperature of the hot air blown by the hot air generator 16. The burner 17 is proportionally controlled so that the temperature of the hot air reaches the set temperature. Although the proportional control is not required, the temperature of the hot air is stabilized by performing the proportional control.

茶葉は、搬送機６によって乾燥室１１の上方の投入口２１より投入され、製茶が完了すると、下部の取出扉２２が開いて、搬送機６上に排出される。粗揉機制御装置１Ａは、粗揉機１の主軸１２の駆動、バーナ１７および送風ファン１８、温度センサや、茶葉の水分を計測するための水分計（図示しない）の制御等を行なう。   The tea leaves are introduced by the carrier 6 from the upper inlet 21 of the drying chamber 11, and when the tea making is completed, the lower take-out door 22 is opened and the tea leaves are discharged onto the carrier 6. The rough kneader control device 1A controls the main shaft 12 of the rough kneader 1, the burner 17, the blower fan 18, a temperature sensor, a moisture meter (not shown) for measuring the moisture content of tea leaves, and the like.

本発明の制御に関する基本的な流れについて、図６を参照して説明する。粗揉機制御盤１Ａの電源を入れ、粗揉機１を起動して、バーナ１７と送風ファン１８の電源を入れると、バーナ１７と送風ファン１８の待機が始まり、バーナ１７は停止、送風ファン１８は最低風量となって、茶葉が粗揉機１へ投入された信号を待つ。最低風量は、本実施例では送風ファンの能力の２０％とするが、１５％でも２５％でも３０％でもよく、バーナ１７の周囲が室温程度になれば停止してもよく、その場合最低風量は０％となる。茶葉が粗揉機１へ投入された信号が来ると、バーナ１７を燃焼させ、送風ファン１８の送風を設定値にし、供給する熱風を設定値になるように制御する。設定した熱風温度より計測した熱風温度が高くなればバーナ１７の燃焼を弱くし、設定した熱風温度より計測した熱風温度が低くなればバーナ１７の燃焼を強くする。製茶中は、設定値になるように、熱風の温度と風量を制御する。設定した温度と風量の熱風により、茶葉は製茶がおこなわれる。あらかじめ設定した時間または水分になると、茶葉は粗揉機１から取り出される。この茶葉が取り出されたときの信号または粗揉機１の中が空であることを検知すると、バーナ１７が停止し、送風ファン１８は最低風量とする。この送風ファン１８を最低風量にするタイミングは、バーナ１７を停止させると同時、またはバーナ１７を停止させてから一定時間経過後のどちらでもよい。次に再び茶葉が粗揉機１へ投入された信号が来るまで、この待機状態を保つ。再び茶葉が粗揉機１へ投入されると、バーナ１７が燃焼し、送風ファンを設定風量にして、１〜２分の短い時間で熱風温度を設定値（茶期や茶葉の性状によって異なるが、８０〜１００℃程度）にする。なお、乾燥室１１内が空になるとほぼ同時に茶葉が投入され、乾燥室１１内が空にならない場合は、製茶のための制御が再びおこなわれる。茶葉の投入、取出の信号は、粗揉機１に備えられた茶葉検知手段による信号、搬送制御盤６Ａによる信号、ライン制御盤８Ａによる信号のいずれでもよい。   A basic flow relating to the control of the present invention will be described with reference to FIG. When the power of the roughing machine control panel 1A is turned on, the roughing machine 1 is started, and the burner 17 and the blower fan 18 are turned on, the burner 17 and the blower fan 18 start to stand by, the burner 17 is stopped, and the blower fan 18 is The minimum air volume is reached, and waits for a signal that tea leaves have been put into the rough kneader 1. The minimum air volume is 20% of the capacity of the blower fan in this embodiment, but may be 15%, 25%, or 30%, and may be stopped when the area around the burner 17 reaches about room temperature, in which case the minimum air volume. Is 0%. When a signal indicating that tea leaves have been put into the rough kneader 1 is burned, the burner 17 is burned, and the blowing air of the blowing fan 18 is set to a set value, and the hot air supplied is controlled to be the set value. When the measured hot air temperature is higher than the set hot air temperature, the combustion of the burner 17 is weakened, and when the measured hot air temperature is lower than the set hot air temperature, the combustion of the burner 17 is strengthened. During tea making, the temperature and volume of hot air are controlled so as to reach the set values. Tea leaves are produced by the hot air having the set temperature and air volume. At a preset time or when the water content is reached, the tea leaves are taken out from the coarse kneader 1. When the signal when the tea leaves are taken out or when it is detected that the inside of the rough kneader 1 is empty, the burner 17 is stopped and the blower fan 18 is set to the minimum air volume. The timing at which the blower fan 18 is set to the minimum air volume may be at the same time when the burner 17 is stopped, or after a certain time has elapsed since the burner 17 was stopped. Next, this standby state is maintained until the signal that tea leaves are thrown into the rough kneader 1 again comes. When the tea leaves are again fed into the coarse kneader 1, the burner 17 is burned, the blower fan is set to the set air volume, and the hot air temperature is set to a set value in a short time of 1 to 2 minutes (depending on the tea season and the characteristics of the tea leaves, 80 to 100 ° C.). When the inside of the drying chamber 11 is emptied, tea leaves are introduced almost at the same time, and when the inside of the drying chamber 11 is not emptied, the control for tea making is performed again. The signals for introducing and removing tea leaves may be any of the signals from the tea leaf detecting means provided in the rough kneader 1, the signals from the transport control board 6A, and the signals from the line control board 8A.

本実施例における省エネルギー率は約２０％と高い。本実施例の装置は、省スペースともなり、製茶工場内で作業スペースや通路を確保することができる。   The energy saving rate in this embodiment is as high as about 20%. The apparatus of the present embodiment also saves space and can secure a working space and passage in the tea factory.
