The Guedu vertical dryers (photo) offer benefits for drying powders in the chemical process industries, including cosmetics and food applications. The vertical dryers operate differently than hot-air and tray dryers. Powder is stirred under vacuum, which shortens the drying time by a factor 2 to 10 compared to tray dryers. Also, by reducing the necessary handling, a similar shortening of the total cycle time is achieved, says the manufacturer. The improved heat transfer during drying leads to a reduction in utilities costs. Mechanical mixing during drying leads to an improved product homogeneity, and the product emerges with residual moisture values below 0.1% where required, says the company. — De Dietrich Process Systems, Niederbronn Cedex, France
