【考案の詳細な説明】 ［産業上の利用分野］ この考案は、緑茶製造機械へ熱風を供給する熱風発生器
のうち、特にガスバーナーを燃焼させて、その燃焼ガス
を直接熱風として利用するものに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hot air generator for supplying hot air to a green tea manufacturing machine, in particular, a gas burner that is burned and the combustion gas is directly used as hot air. Regarding
［従来の技術］ このような、ガスバーナーによる熱風の発生方法は、主
として、中揉工程で行われている。[Prior Art] Such a method of generating hot air by a gas burner is mainly performed in a middle kneading process.
中揉機は、揉室を形成する回転胴の片側面に吸引ファン
を設け、回転胴の他側面に熱気吸込口を設け、この吸込
口付近で、ガスバーナーを燃焼させて、燃焼ガスをその
まま外気と共に吸引させて、熱風として利用しているも
のが多い。The middle kneader has a suction fan on one side of the rotary cylinder that forms the kneading chamber, and a hot air inlet on the other side of the rotary cylinder.The gas burner is burned near this inlet to burn the combustion gas to the outside air. Many of them are sucked together and used as hot air.
一部に実願昭50−29873号のように熱風送り込みのファ
ンを設けたものもある。Some of them have a fan for sending hot air, as in Japanese Utility Model Application No. 50-29873.
［考案が解決しようとする課題］ 従来のように外気吸込口でガスバーナーを燃焼させるだ
けでは、外気と燃焼ガスが十分に混合しない。この為非
常に熱い空気と、冷たい空気がそのまま機内に入り乾燥
ムラが発生する。[Problems to be Solved by the Invention] Just by burning the gas burner at the outside air inlet as in the past, the outside air and the combustion gas are not sufficiently mixed. Therefore, very hot air and cold air flow into the machine as they are, causing uneven drying.
高温の燃焼ガスと空気がよく混合していないので、温度
センサーで熱風温度を測定することが困難であり、熱風
の温度を制御することができない。Since the hot combustion gas and air are not mixed well, it is difficult to measure the hot air temperature with a temperature sensor, and the hot air temperature cannot be controlled.
特に、中揉工程では、原葉の状態により熱風量を大きく
変化させる必要があり、実願昭50−29873号のように、
バーナー及び燃焼室が横置であると、熱風量を下げた場
合、燃焼ガスが上側に逃げる為、安定した熱風が得られ
ない。In particular, in the middle kneading process, it is necessary to greatly change the amount of hot air depending on the state of the raw leaves.
When the burner and the combustion chamber are placed horizontally, when the amount of hot air is reduced, the combustion gas escapes to the upper side, and stable hot air cannot be obtained.
本考案は、製茶機械の運転状態に影響を受けることなく
常に安定した均一な熱風を製茶機械に供給することを目
的とする。An object of the present invention is to always supply stable and uniform hot air to a tea making machine without being affected by the operating state of the tea making machine.
［課題を解決する為の手段］ 本考案では、単にガスバーナーによる燃焼ガスを本機の
吸引ファンで外気と共に吸い込ませるのではなく、本機
の吸引ファンとは別に吸込口に送風ファンを設け、更
に、この送風ファンの空気吸込口を下向きにし、その下
方にガスバーナーを上向きに設置することを特徴として
いる。[Means for Solving the Problems] In the present invention, instead of simply sucking the combustion gas by the gas burner together with the outside air with the suction fan of this machine, a blower fan is provided at the suction port separately from the suction fan of this machine, Further, it is characterized in that the air suction port of the blower fan is directed downward and the gas burner is installed downward below it.
［作用］ ガスバーナーによる燃焼ガスは空気と共に吸引され、送
風ファンを通ることにより、高温の燃焼ガスと空気が混
合し、均一な温度の熱風となる。[Operation] Combustion gas from the gas burner is sucked together with air, and by passing through a blower fan, the high-temperature combustion gas and air are mixed to form hot air of uniform temperature.
ガスバーナーによる高温の燃焼ガスは、空気の対流によ
り自然に上昇する。ガスバーナー上部に送風ファンの吸
込口があるので、どのような熱風量の状態でも燃焼ガス
は外部へ逃げることなく、そのまま送風ファンへ吸引さ
れる。The hot combustion gas from the gas burner naturally rises due to air convection. Since the blower fan has a suction port at the upper part of the gas burner, the combustion gas is sucked into the blower fan as it is without escaping to the outside regardless of the amount of hot air.
［実施例］ 本考案を製茶中揉機に実施した場合について説明する。[Example] A case where the present invention is applied to a tea making and kneading machine will be described.
中揉機は、回転胴７を挟んで一端に吸引ファン13があ
り、他端から熱風を吸引して回転胴７内の茶葉を揉乾す
る。The middle kneader has a suction fan 13 at one end across the rotary drum 7, and sucks hot air from the other end to dry the tea leaves in the rotary drum 7.
本考案の熱風発生器Ａは熱風供給側へ装着する。１は送
風ファンであり、空気吸込口を下に向け、その下方にガ
スバーナー９を上向きに設ける。10はファイヤーブリッ
ジである。これらの周囲はカバー12で覆う。The hot air generator A of the present invention is installed on the hot air supply side. A blower fan 1 has an air suction port facing downward, and a gas burner 9 provided upward below the air suction port. 10 is a fire bridge. The periphery of these is covered with a cover 12.
中揉機の熱風供給側は手前側が作業者の操作面になるの
で、送風ファン１は後側へ設け、送風ファンからの熱風
をダクト３で熱風供給口２へ誘導する、ダクト３は間隙
イを保ってダクト４で囲い、ダクト４は熱風供給口２へ
接続する。Since the front side of the hot air supply side of the middle kneader is the operator's operation surface, the blower fan 1 is provided on the rear side, and the hot air from the blower fan is guided to the hot air supply port 2 by the duct 3. The duct 3 has a gap b. It is kept and surrounded by a duct 4, and the duct 4 is connected to the hot air supply port 2.
ガスバーナー９の炎はファイヤーブリッジ10を加熱し、
ガスの燃焼をより完全にする。高温の燃焼ガスは、空気
と共にファン１の下側から吸引され、ファンローターの
回転により混合されて、ダクト３により、熱風供給口２
へ向って吹き出され、中揉機の吸引ファン13により、回
転胴７内へ吸引される。The flame of the gas burner 9 heats the fire bridge 10,
Make the gas combustion more complete. The hot combustion gas is sucked together with air from the lower side of the fan 1 and mixed by the rotation of the fan rotor, and the hot air supply port 2 is supplied by the duct 3.
It is blown out toward and is sucked into the rotary drum 7 by the suction fan 13 of the central kneading machine.
吸引ファン13の風量より、送風ファン１の風量をわずか
に少なくしておけば、その差の分の空気が間隙イを通っ
て、中揉機内へ吸引される。If the air volume of the blower fan 1 is set to be slightly smaller than the air volume of the suction fan 13, the air corresponding to the difference is sucked into the inside kneader through the gap i.
熱風供給口２には温度センサー５が設けてあり、設定温
度になるようにガスバーナー９の燃焼を自動的に調節す
る。The hot air supply port 2 is provided with a temperature sensor 5, which automatically adjusts the combustion of the gas burner 9 to reach a set temperature.
［考案の効果］ 本考案は、ガスバーナーによる燃焼ガスを送風ファンで
空気と混合して均一な温度の熱風を供給するので、茶葉
が高温の燃焼ガスに触れてこげたり、乾燥ムラを生じり
することがなく、温度センサーによる熱風温度の制御も
正確に行うことができる。[Advantage of the Invention] In the present invention, the combustion gas from the gas burner is mixed with the air by the blower fan to supply the hot air with a uniform temperature, so that the tea leaves touch the high-temperature combustion gas and burn, and uneven drying occurs. Without doing so, the hot air temperature can be accurately controlled by the temperature sensor.
吸引ファンだけで熱風の供給を受ける場合は、中揉機内
の茶葉の量や、状態で吸引力が変わり熱風の状態が変動
するが、本考案では送風ファンにより強制的に熱風を送
り込むので常に安定した熱風を供給でき、製品の品質と
製茶の能率を上げることができる。When the hot air is supplied only by the suction fan, the suction force changes depending on the amount and condition of the tea leaves in the middle kneader and the state of the hot air fluctuates, but in the present invention, the hot air is forcibly sent by the blower fan, so it is always stable. The hot air can be supplied to improve the product quality and tea production efficiency.
送風ファンの空気吸入口を下に向け、その下方にガスバ
ーナーがあるので、どのような風量のときでも燃焼ガス
は上に上がり、自然に送風ファンに吸い込まれるので、
完全な燃焼を行うことができる。With the air inlet of the blower fan facing down and the gas burner underneath it, the combustion gas rises upward at any air volume and is naturally sucked into the blower fan.
Complete combustion can be performed.
実施例では、送風ファンを後側に設けてあるので、前面
が空き、作業者がバーナーの熱を受けることなく安全か
つ容易に作業を行うことができる。In the embodiment, since the blower fan is provided on the rear side, the front surface is open and the worker can safely and easily perform the work without receiving the heat of the burner.
又、熱風ダクト３の外をダクト４で囲ってあるので、作
業者は高温のダクト３に直接触れることがないので安全
である。ダクト３の保温効果もあり、間隙イから吸入さ
れる空気の予熱効果も期待できて、熱効率を良好にする
ことができる。Also, since the outside of the hot air duct 3 is surrounded by the duct 4, the worker does not touch the hot duct 3 directly, which is safe. There is also a heat retaining effect on the duct 3, and a preheating effect of the air sucked through the gap B can be expected, and thermal efficiency can be improved.
