本研究目的係選用三種不同市售噴嘴並建立其量測系統來模擬測試當進行生物菌絲體液態接種應用時之實驗量測結果,於不同高度施以不同壓力與時間,來觀察測試其噴灑之角度、寬度、面積與流量變化,以及噴霧之均勻程度與平均粒徑大小等。噴嘴試驗條件分別設定入口壓力為0.2 MPa、0.3 MPa、0.4 MPa、0.5 MPa,噴霧時間為0.2 s、0.4 s、0.6 s、0.8 s,噴嘴高度變化係以1 cm、2 cm、3 cm來進行觀察測試。另外,本研究以高速攝影機來拍攝並記錄噴嘴之噴霧變化情形,每張照片拍攝時間間隔約為0.04 s,藉以觀察噴嘴從出口到噴霧面的噴霧情況。流量部分是用量筒來測量噴嘴在特定的時間內(0.2 s、0.4 s、0.6 s、0.8 s)流量之變化。綜合上列研究結果,可用來比較噴嘴的適用性,選定較適合之噴嘴以供農業生技業者在做液態生物菌絲體噴嘴系統與自動化接菌機機台設計時之參考。 關鍵字:噴嘴、噴霧、液態接種,生物菌絲體。
The purpose of this study was the choice of three different commercially available nozzles and establish its measurement system to simulate the test results when performing the experimental measurements of biological applications when inoculated with mycelium of liquid at different heights subjected to different pressures and time, to observe the testing of its spray the angle, width, area and the flow rate changes, and uniformity of the spray with the average particle size. Test conditions were set nozzle inlet pressure of 0.2 MPa, 0.3 MPa, 0.4 MPa, 0.5 MPa, the spray time was 0.2 s, 0.4 s, 0.6 s, 0.8 s, nozzle height change lines to 1 cm, 2 cm, 3 cm to observe the test. In addition, this study high-speed cameras to capture and record the variations of spray nozzles, each photo shoot time interval is approximately 0.04 s, in order to observe the spray nozzle from the surface of the spray outlet to the situation. Flow part is a graduated cylinder to measure the nozzle within a specific period of time (0.2 s, 0.4 s, 0.6 s, 0.8 s) changes in flows. Comprehensive above findings can be used to compare the suitability of the nozzle, the nozzle selected more suitable for agricultural biotechnology industry in a reference liquid bio mycelium inoculation nozzle system with automated machine when the machine design. Keywords: a nozzle, spray, liquid inoculation biological mycelium.
