Drying process

Dryer technology

Keller various solutions ensure energy-saving and gentle drying of the products. Thanks to our K-Matic process control system, we always guarantee reliable control of the drying process, an optimum overview, repeatability and extensive process evaluation options.

Our various dryer types, such as tunnel and chamber dryers, ensure energy-saving and gentle drying of your products. Thanks to our K-Matic process control system, we always guarantee reliable control of the drying process, an optimum overview, repeatability and extensive process evaluation options.

If very individual drying times and drying curves are required, these can be ideally realized with the Keller chamber dryers. With consistent drying conditions, Keller tunnel dryers offer the best conditions for energy-efficient drying with high throughputs and first-class product quality.

Heat recovery

Energy recovery is crucial to increasing energy efficiency. This involves extracting energy from exhaust gas flows and feeding it back into the process.

This happens, for example, with:
  • a recovery of wet air energy at the dryer
  • coupled with the use of heat pumps
  • the use of heat exchangers in the flue gas made of metal and polymer

Engineering

Energy consumption during drying and firing is directly related to heat transfer and flow conditions.
CFD calculations help to find thermodynamically and fluid-dynamically optimized solutions in advance. This is why we use them.
