省能省時塑膠粒乾燥機之研發

THE R&D on Energy and Time Saving Plastic Resin Dryer

指導教授 : 黃景良

摘要


本文針對塑膠粒傳統熱風乾燥機耗能耗時的缺失,尋求新型快速乾燥方法和設備的研究。 本研究發現紅外線(IR)乾燥機雖可省時,但IR無法穿透2cm以上厚度的塑膠粒層,因而單位時間總乾燥量不足,且耗電量過大,不符合實際需求及成本效益。 本研究研發之新型微波乾燥機,對塑膠粒乾燥以達到含水率低於0.02%之國際標準時,對省時以及省電上均有明顯效果: (1)乾燥溫度比熱風乾燥機降低13℃以上,比除濕乾燥機降低12℃以上。 (2)乾燥時間比熱風乾燥機和除濕乾燥機均節省200%以上。 (3)耗電量比熱風乾燥機節省142%以上,比除濕乾燥機可節省488%以上。

This thesis develops a new method and its relative equipment of fast drying for plastic resin to eliminate the shortages of traditional heating air dryers that will waste time and energy. In this study, we found that although the IR dryer can save time, but IR cannot penetrate the plastic resin layer with the thickness more than 2cm; thus it is not good for the total dry weight per unit time, and the power consumption is too high as well. Therefore, the IR dryer cannot match the practical requirements and obtain the cost benefits. The present developed new dryer performs effectively in saving energy and time for the dry plastic resin under the international standard of moisture content reaching below 0.02%: (1) Its drying temperature lower than that of heating air dryer over 13℃ and that of dehumidifying dryer over 12℃. (2) Its drying time is lower than that of heating dryer and that of dehumidifying dryer over 200%. (3) Its drying power consumption is lower than that of heating dryer over 142% and that of dehumidifying dryer over 488%.
