 您對真空冷凍干燥機了解多少?

 

 

真空冷凍干燥機又稱冷凍干燥機,通常其工作原理簡單地理解為:在真空低溫環境下,將物料中的水分冷凍成固體,再轉化為氣體升華,從而得到凍干物料。

  根據熱力學相平衡理論,水的三相點(汽、液、固共存)的溫度為0.0098℃,水三相點壓力為609.3pa(4.57mm/mg)。在水的相變過程中,當壓力低于水三相點的壓力時,固體冰可以直接轉化為氣態水蒸氣,即冰晶升華。本產品是對含有大量水的物料進行預凍,使物料中的游離水結晶凝固成固體,然后在真空條件下使物料中的冰晶升華,冰晶升華后除去物料中的部分吸附水,后得到凍干材料。一般情況下,95-99%的水分可以通過冷凍干燥去除。

  真空冷凍干燥機的主要組成部分都有哪些呢?

  1、干燥倉

  它是一種具有抽真空和加熱干燥功能的密封容器。物料的升華干燥過程在干燥倉中完成。材料放在干燥室架子上的不銹鋼托盤中。每個貨架上都有一個測量物料溫度的探頭,用于監控物料在整個凍干過程中的溫度。

  2、捕水器(冷井)

  它是一個用于冷凝和升華水蒸氣的封閉裝置,通常位于干燥箱的后部。內部有大面積的金屬吸附表面。干燥倉內物料升華后的水蒸氣可在金屬表面凝結吸附。吸附表面的工作溫度可達-45℃℃~-65℃、冷凝器的形狀為不銹鋼或鐵制成的圓筒,內部有冷凝管,分別與制冷機組相連,形成制冷循環系統。

  3、供暖系統

  凍干機加熱系統的作用是對干燥倉內的物料進行加熱,使物料不斷加熱升華,達到規定的含水率要求。凍干機加熱系統的加熱方式主要分為接觸加熱和輻射加熱。

  接觸加熱采用循環介質加熱方式。加熱系統工作時,首先對循環液體進行加熱,液體溫度由液箱控制調節器選定的溫度自動控制。管道泵啟動后,循環液進入干燥箱中的擱板加熱擱板,再返回液箱進行加熱循環。當循環介質為硅油時,膜片的高溫可達(+60~+70)℃、

  4、真空系統

  真空系統由真空泵和羅茨真空泵組成。羅茨泵是增壓泵,不能單獨使用。須先啟動真空泵,使其工作一段時間。當系統真空度達到1kPa以下時,羅茨泵自動啟動。真空泵和羅茨泵的結構如說明書所示。真空系統的真空計可采用電接點真空計,根據預先選定的真空值自動控制羅茨泵的啟動。

  5、制冷系統

  真空冷凍干燥機的制冷系統由制冷壓縮機組、R22或R404A制冷劑組成。一般來說,速凍制冷系統和凍干設備的捕水器制冷系統共用一個制冷系統。當系統工作時,貨架溫度可以降低到-35℃在接觸加熱模式下。制冷系統工作時,冷凝盤管表面溫度可達-35~-65℃、根據用戶需要,可采用低溫螺桿式或兩級活塞式制冷壓縮機組。一般來說,兩級活塞式壓縮機具有較好的制冷效果和較低的制冷溫度。
