VetterTec TECHNOLOGIES

Ring and Flash Dryers

The VetterTec Ring and Flash Dryer technologies are pneumatic type drying systems well-known for their reliability and drying efficiency. Our Ring and Flash Dryer systems are suitable for drying a range of products from wet cakes to wet pastes.

Optimal wet product preparation is part of our specially designed and easily cleanable wet product feed system forming an integral part of our dryers. Based on our extensive experience, VetterTec carefully selects each part of our drying systems, including, for example, upstream mechanical dewatering and downstream Milling and Cooling to suit each specific application.

As a leading supplier, VetterTec builds on its proven, innovative solutions to ensure that all our drying systems meet our customers’ changing needs while continuously delivering optimal product quality.

The Flash Dryer – Principle of Operation

The Flash dryer is a single-pass, pneumatic type drying system which offers gentle drying due to its short residence time. The dryer can be either indirectly heated (steam, thermal oil, waste heat or natural / biogas) or directly heated (waste heat or natural / biogas). Depending on product and / or emission requirements, either single or multi-stage cyclones (with option for special suction discharge), cyclone and bag filter combination or bag filter only can be used for product collection.

The Full Ring Dryer – Principle of Operation

The Full Ring Dryer is a multi-pass, pneumatic type drying system with a multi or single stage classifier for selectable particle residence time which offers gentle drying due to its overall short residence time. The dryer can be either indirectly heated (steam, thermal oil, waste heat or natural / biogas) or directly heated (waste heat or natural / biogas). Depending on product and / or emission requirements either single or multi-stage cyclones (with option for special suction discharge), cyclone and bag filter combination or bag filter only can be used for product collection.
