藉由設計與實驗，改變噴嘴的空氣流道的幾何形狀，尋求構造佈局簡單，氣體噴流均勻的噴嘴流道，應用於乾燥爐噴嘴的空氣流道。乾燥爐於生產運作時，空氣噴嘴出口的空氣流速平均，被加熱物體所接收的熱量均勻，減少因為噴嘴出口的空氣流速不平均所造成的能源損失，以達到提高熱能使用效率，降低設備製造成本與提昇使用者生產效率的目的。
設計活動式漸縮導流板於空氣流道內作角度的調整，藉著調整這片導流板的角度，改變漸縮空氣流道的漸縮尺寸。於噴嘴的漸縮位置每50mm配置導流板、配置兩片導流板與沒有導流板。實驗以三種不同的空氣壓力條件，調整空氣噴嘴內漸縮導流板全開、半開、全閉等三種不同的位置，作噴嘴口風速與空氣流道空氣壓力的量測，以觀察於供應不同的空氣壓力與不同的流道漸縮角度，對每50mm配置導流板、配置兩片導流板與沒有導流板等三種空氣噴嘴的噴嘴口風速與空氣流道空氣壓力影響。

By designing and experiment, change air duct geometric form , simple to seek structure, gas is it flow speed even air nozzle to gush out, apply to the air nozzle of the dry oven . When the dry oven is in production operation, the velocity of flow of air that the air nozzle exports is average, it is even to heat the heat absorbed of object, in order to reach and improve heat energy service efficiency, achieve and reduce the manufacturing cost of the equipment and purpose to raise user’s production efficiency . Design the activity type and draw back the air diversion board and make the adjustment of the angle in the air duct, make use of adjust the angle of draw back the air diversion board, is it contract air shed to contract size more and more dish gradually to change. Every 50mm position gradually and disposing the air diversion board in nozzle, disposes two slices of air diversion boards and there is no air diversion board. With three different air pressure terms, and air diversion board adjust for turn on, not half-open all, all close three kinds of different positions at the experiment, quantity examines the wind speed of the nozzle, the air pressure in one that quantity examines the air and air duct. Observe the wind speed of the nozzle and air pressure in the air duct under the influence, about the three kinds of air nozzle that every 50mm position gradually and disposing the air diversion board in nozzle, disposes two slices of air diversion boards and there is no air diversion board in nozzle, on different air pressure of supplying with different angle gradually of air duct.
