VetterTec Flash and Ring Dryers
VetterTec s r e y r D g n i R d n a h s a l F VetterTec VetterTec Flash and Ring Dryers VetterTec has an established reputation, with proven designs and competitive solutions for flash and ring dryer applications. VetterTec flash and ring dryers are ideal for drying filter cakes, fibrous materials, sludges and slurries. Advantages Simple, economic design High reliability Uniform co-current drying, giving gentle treatment of the material and improved product quality Short residence time ideal for heat sensitive products Easy maintenance Options for direct and indirect heating configurations Self-inertising options available Can incorporate odour destruction through incineration ec.de www.vettert Industries Starch Ethanol Food Dairy Chemicals Pharmaceuticals Minerals „successful drying systems“ s r e y r D g n i R d n a h s a l F VetterTec VetterTec Dryers – for high quality powders VetterTec flash dryers are used to produce fine granular or powdered material when short residence times are required. A stream of turbulent hot air dries the product whilst it is being conveyed co-currently in a continuous process. Rapid evaporation ensures that the product temperature is maintained as low as possible, ideal for heat sensitive materials. VetterTec ring dryers are flash type dryers which incorporate a centrifugal classifier to increase the residence time selectively for the wetter and larger material. Within the classifier, drier and finer particles are separated out from larger and moister particles. Adjustable blades in the classifier allow the degree of separation to be set to optimise dryer performance. Larger particles are recirculated through the dryer, normally through a disintegrator, that provides size reduction, and this extended residence time allows efficient drying of many different products that cannot be flash dried. Flash Dryer VetterTec flash and ring dryers can be supplied in open circuit, partially closed circuit and fully closed circuit operation. A partially closed circuit allows drying efficiency to be increased by recirculating a majority of exhaust gases back into the dryer, thus minimising heat release in exhaust air and providing self-inertisation. Fully closed circuit systems enable operation at higher wet bulb temperatures and maximize energy recovery in the evaporator. Ancillary equipment supplied with VetterTec plants include back-mixers, special feeders, wet scrubbers, solvent recovery systems and bag filters. A VetterTec pilot plant is available for carrying out tests on a variety of products. ec.de www.vettert VetterTec Ltd 154 High Street Sevenoaks. Kent TN13 1XE.
