Lödige shovel dryers are batch vacuum dryers. The mixing elements are frequency-controlled for ideal adaptation to the process. Special rotating mixing elements, installed in a cylindrical drum equipped with a temperature control jacket, create a three-dimensional product movement . The resulting contact frequency of the particles with the heat exchange surface leads to incredibly short drying times. The intelligent product movement ensures intense contact of individual product particles with the heated container wall while also providing very gentle product treatment. The chopper rotating at high speeds is used to disperse the product during transition between phases. Product surfaces are opened up during this process. This leads to a significant increase in drying capacity and prevents moisture and temperature gradients. Fine particles pulled along by solvent vapours are separated in the filter and returned to the product bed through pneumatic filter cleaning.

In addition to filtration, compressed-air drying contributes significantly to an increase in process reliability. Humidity in compressed-air systems causes corrosion, and promotes the growth of micro-organisms. In individual cases, condensate emerges at the point of use - an ongoing danger for the operational flow, for example because of failing pneumatic controls, increased wear and tear or because of other disturbances in the production process. With considerably enhanced process reliability, the DRYPOINT dryer technology offers decisive advantages for every field of application. The BEKO TECHNOLOGIES portfolio comprises application-optimised refrigeration, adsorption and membrane dryers for volumes up to 1,500 m³/h. This range of dryers is completed by heat-regenerated EVERDRY adsorption dryers which are designed for large volume flows up to 20,000 m³/h.

Each of us has faced the problem of drying towels in the kitchen, especially during the cold season. If the towels do not get dry quickly, they get an unpleasant odor and become dirty very quickly. The solution to this problem is an infrared towel dryer
