The Vertical Screw Belt Dryer mixing the sticky liquid from the bottom to upside and then dropped from top. During this process, the entire equipment cavity maintains a constant temperature.The contact area of the material with heat area increases, thereby accelerating the drying speed. Furthermore, the screw belt itself is heated and sheared, not simply stirring. This makes it ideal for heat-sensitive, viscous materials.
However, the Horizontal Screw Belt Dryer has dead corners, and viscous materials will clog the wall of the equipment and ultimately cannot be dried.
Vertical dryers were developed to address the shortcomings of horizontal dryers, offering superior performance in all aspects, so the price is slightly higher.Vertical screw belt dryer is also commonly used in the pharmaceutical field and is a slightly more advanced device.This will also save you significant R&D costs and time.
