【考案の詳細な説明】 本考案は薪、木材などの固形燃料を主体とし補助的に灯
油、重油などの石油燃料を使用する混合燃料を自動的に
調節し得る熱風乾燥装置を提供するものである。[Detailed description of the invention] The present invention provides a hot air drying device that can automatically adjust the mixed fuel that mainly uses solid fuel such as firewood and wood and supplementary petroleum fuel such as kerosene and heavy oil. be.

従来前と石油との混焼に関しては衆知のところであるが
、薪、木材などの固形燃料を補給する時期を逸すること
が多く、更に燃焼か′悪く、待ち炉内奥の燃料が焼遅れ
る傾向にあり、又炭化されて積層し、燃料の補給にも困
惑し、燃焼熱が低下する結果、燃焼途中石油に切換るこ
とか多く専ら石油燃料に依存する傾向にあった。It is well known that conventional mixed combustion with petroleum is a common problem, but the timing of replenishing solid fuels such as firewood and wood is often missed, which makes the combustion worse, and the fuel in the back of the waiting furnace tends to be delayed. However, as fuel is carbonized and piled up, it is difficult to replenish fuel, and as a result of the reduction in combustion heat, there has been a tendency to rely exclusively on petroleum fuel, often switching to petroleum during combustion.

本案は固形燃料の燃焼熱の効率を計るべく送風機の先端
を燃焼炉床面に沿わしめて多孔管として炉奥端まで挿入

灰化される装置の送風機とバーナーの石油燃料とを自動
制御させ、固形燃料の消失の予告と高温危険信号のブザ
ーを鳴らす如く装置せしめるものである。In order to measure the efficiency of combustion heat of solid fuel, the tip of the blower is placed along the surface of the combustion hearth and inserted into the deep end of the furnace as a perforated tube, and outside air is blown out in the form of a jet to supply air, which is then ashed through complete combustion. This system automatically controls the blower and petroleum fuel in the burner of the device, and makes the device sound a buzzer to warn of the disappearance of solid fuel and to signal a high temperature danger signal.

点式温度調節器の働きによりバーナー３を停止させ、な
お上昇し温度が５０℃になれば送風機６を停止する。In this example of shiitake mushroom drying, the purpose is to maintain the drying temperature at 49 to 51°C, and solid fuel is put into the combustion furnace 4.
Burner is assisted by burner 3 and blower 6, and when the temperature reaches 45℃ by thermostat 10 in the drying box, 4
The burner 3 is stopped by the action of the spot temperature regulator, and if the temperature continues to rise and reaches 50°C, the blower 6 is stopped.

少にとどまらしめ省エネルギーに寄与するところ大であ
る。During this period of combustion, if the blower 6 drops below 50°C, it is energized, and when the air blowing into the combustion furnace is restarted from the perforated pipe, the temperature rises, and the air blown from the perforated pipe is blown in the form of a jet over the entire inside of the furnace. It is easy to replenish the solid fuel with a small amount of residue in the furnace because it is completely combusted and ashed, and there is almost no burner assistance that reduces combustion efficiency. It is possible to maintain the temperature at approximately ~51°C and to achieve the highest quality, while minimizing petroleum resources, which greatly contributes to energy conservation.
