You are interested in using a heat pump dryer in your industrial drying process, but are not sure how to proceed?
Heat pump-assisted drying systems are highly energy-efficient alternatives to conventional thermal dryers. They are therefore increasingly attractive for industrial applications. Several companies are already demonstrating its effective use. See the case studies compiled by the Annex 59 project team for the food, feed, ceramics and biomass sectors. By recovering and...
