Advantageous alternative technology in vertical dryer

A new solution from De Dietrich Process Systems has added benefits for the drying of powders in process industries, cosmetics and food. The Guedu vertical dryers have been installed by several manufacturers, and resulted in productivity improvements. The short cycle times have also reduced handling.

The vertical dryer is unlike hot air dryers and tray dryers. The powder is stirred under vacuum, that allows an improvement of the drying time by a factor 2-10 compared to tray dryers, and a total cycle time reduction by a similar ratio (by reducing the necessary handling).

In fact, the vacuum drying technology allows savings due to the total cycle time reduction (a single pan dryer can replace several tray dryers) and also savings from the improved heat transfer during drying (reducing utilities costs).

The mechanical mixing during drying improves product homogeneity. Therefore, at the end of the cycle, the product comes out perfect evenly dried, with residual moistures below 0.1% where required.

De Dietrich Process Systems provides not only the appropriate drying technology, but also designs and supplies the peripheral equipment, support structure as well as the automation and control systems.
