閃蒸干燥機用于從離心蛋糕或粉末干燥殘留水分。

干燥過程是通過用熱空氣在高的速度行駛的粉末接觸。用于干燥的熱空氣氣動輸送的粉末的分離在旋風分離器或袋式過濾器。一個產品分類，確保只有的干粉離開干燥室。

修改后的版本的閃蒸干燥機是一個環(huán)形干燥機，采用了離心式分級機，使用導流葉片的選擇和分類的基礎上，其密度空氣中的顆粒。由于離心力作用的結果，行為及多雨顆粒按照環(huán)管周更加緊密和再循環(huán)回到，而細的干燥材料與排氣的空氣被收集在旋風分離器或袋式過濾器是在洗滌之前離開干燥器文丘里洗滌器。

A flash dryer is used to dry residual moisture from centrifuged cakes or powders.

Drying process is accomplished by contacting the powder with hot air travelling at high velocity. The heat is used for drying and the air pneumatically conveys the powder for separation in a cyclone or a bag filter. A product classifier ensures only dry powder leaving the drying chamber.

A modified version of a flash dryer is a Ring Dryer and incorporates a centrifugal classifier that uses deflector blades to select and classify air borne particles on the basis of their densities. As a result of centrifugal action, the behavior and wetter particles follow the ring duct periphery more closely and are recycled back, while the fine dried material leaves the dryer with the exhaust air to be collected in the cyclone or bag filter before being scrubbed in a venturi scrubber.
