DRYER

To provide a dryer capable of making the temperature distribution of drying gas in a drying zone uniform, and of effectively utilizing heat of drying gas.SOLUTION: A dryer 10 according to an embodiment of the present invention dries a drying object W by ejecting drying gas onto the drying object W being conveyed. The dryer 10 comprises: a combustor 20A that generates drying gas for drying the drying object W, drying zones 61A, 61B, 61C, 61D disposed in a direction of conveying the drying object W to dry the drying object W by allowing it to stay therein for a specified period of time, a plurality of drying gas ejection nozzles 100 attached to each of the drying zones 61A, 61B, 61C, 61D to eject drying gas generated by the combustor 20A onto the drying object W, and suction zones 62A, 62B, 62C each disposed between the corresponding drying zones and provided with a suction port 63 to suck and return drying gas ejected into the drying zones 61A, 61B, 61C, 61D to the combustor 20A.SELECTED DRAWING: Figure 1 【課題】乾燥ゾーンにおける乾燥用ガスの温度分布の均一化が図れるとともに、乾燥用ガスの熱量を有効に利用することができる乾燥装置を提供する。【解決手段】実施形態の乾燥装置１０は、搬送される被乾燥物Ｗに乾燥用ガスを噴出して被乾燥物Ｗを乾燥させる。乾燥装置１０は、被乾燥物Ｗを乾燥させる乾燥用ガスを生成する燃焼器２０Ａと、被乾燥物Ｗの搬送方向に設けられ、被乾燥物Ｗを所定時間留めて乾燥させる乾燥ゾーン６１Ａ、６１Ｂ、６１Ｃ、６１Ｄと、各乾燥ゾーン６１Ａ、６１Ｂ、６１Ｃ、６１Ｄに設けられ、燃焼器２０Ａで生成された乾燥用ガスを被乾燥物Ｗに向けて噴出する乾燥用ガス噴出ノズル１００と、乾燥ゾーン間に設けられ、乾燥ゾーン６１Ａ、６１Ｂ、６１Ｃ、６１Ｄに噴出された乾燥用ガスを燃焼器２０Ａに戻すために吸い込む吸込み口６３を有する吸込みゾーン６２Ａ、６２Ｂ、６２Ｃとを備える。【選択図】図１
