簡介
隧道干燥機是一種利用熱能降低物料水分的機械設備,用于對物體進行干燥操作。干燥機通過加熱使物料中的濕分(一般指水分或其他可揮發性液體成分)汽化逸出,以獲得規定濕含量的固體物料。干燥的目的是為了物料使用或進一步加工的需要。
1原理
干燥過程需要消耗大量熱能,為了節省能量,某些濕含量高的物料、含有固體物質的懸浮液或溶液一般先經機械脫水或加熱蒸發,再在干燥機內干燥,以得到干的固體。
在干燥過程中需要同時完成熱量和質量(濕分)的傳遞,保證物料表面濕分蒸汽分壓(濃度)高于外部空間中的濕分蒸汽分壓,保證熱源溫度高于物料溫度。
熱量從高溫熱源以各種方式傳遞給濕物料,使物料表面濕分汽化并逸散到外部空間,從而在物料表面和內部出現濕含量的差別。內部濕分向表面擴散并汽化,使物料濕含量不斷降低,逐步完成物料整體的干燥。
物料的干燥速率取決于表面汽化速率和內部濕分的擴散速率。通常干燥前期的干燥速率受表面汽化速率控制;而后,只要干燥的外部條件不變,物料的干燥速率和表面溫度即保持穩定,這個階段稱為恒速干燥階段;當物料濕含量降低到某一程度,內部濕分向表面的擴散速率降低,并小于表面汽化速率時,干燥速率即主要由內部擴散速率決定,并隨濕含量的降低而不斷降低,這個階段稱為降速干燥階段。
