GEA Barr-Rosin氣流干燥機是一種氣動系統，主要用于干燥產品，需要去除游離水分的。干燥發生在幾秒鐘的事。濕材料被分散到一個流的熱空氣（或氣體），把它傳送通過一個干燥管。
從氣流中使用的熱，因為它被輸送的材料干燥。產品采用旋風分離和/或袋式過濾器。通常情況下，旋風分離器隨后通過洗滌器或袋式過濾器作^后清洗的廢氣，以滿足目前的排放要求。
因為閃爍熄滅，即刻的表面水分的干燥氣體進行冷卻，而不明顯地增加了產品的溫度，升高干燥溫度，可用于許多產品。
對于更大的熱效率和惰性需要的地方，回收廢氣的都可以使用。這可以實現我們所有的氣流干燥系統和翻新改造，對客戶現有的干燥作業。
許多在世界上^大的氣流干燥機- 一些在單個系統中的水分蒸發量每小時超過20噸。進氣口溫度范圍從200 - 1400°F（100℃ - 650℃），而氣流可以超過12萬立方英尺（200000立方米）。
氣流干燥機已用于干燥產品在許多行業中，包括食品，化工，礦物和聚合物。一個廣泛的范圍內的進料，包括粉劑，蛋糕，顆粒，薄片，糊劑，凝膠，淤漿可以被處理。對于泥漿，糊劑，或粘性物料，返混的濕飼料干燥產品的部分，以產生一個合適的空調材料是必需的。
這種技術也可以用于冷卻應用。
GEA Barr-Rosin研究與發展中心配備了中試規模的氣流干燥機進行試驗。
The GEA Barr-Rosin Flash Dryer is a pneumatic system primarily used to dry products requiring the removal of free moisture. Drying takes place in a matter of seconds. Wet material is dispersed into a stream of heated air (or gas) which conveys it through a drying duct.
Using the heat from the airstream, the material dries as it is conveyed. Product is separated using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.
Elevated drying temperatures can be used with many products since the flashing off of surface moisture instantly cools the drying gas without appreciably increasing the product temperature.
For even greater thermal efficiency and where inertisation is required, recycling of exhaust gases can be used. This can be implemented on all our airstream drying systems and retrofitted on customer's existing drying operations.
Many of the largest dryers in the world are flash dryers - some exceeding 20 tons of water evaporation per hour in a single system. Inlet air temperature ranges from 200- 1400°F (100oC -650oC) while airflows can exceed 120,000 cfm (200,000 m3/hr).
Flash dryers have been used to dry products in many industries including food, chemical, mineral and polymer. A broad range of feed materials including powders, cakes, granules, flakes, pastes, gels, and slurries can be processed. For slurries, pastes, or sticky materials, backmixing of the wet feed with a portion of dry product to produce a suitable conditioned material is required.
This technology can also be used for cooling applications.
The GEA Barr-Rosin Research and Development Center is equipped with a pilot scale flash dryer for conducting trials.
