Towards energy-efficient spray drying: Geometric optimization of an ACLR nozzle for atomizing concentrated feeds
Abstract
Spray drying is a key method for large-scale production of food powders but remains among the most energy-intensive processes in the food industry. Increasing the solids content of liquid feeds can lower thermal energy demand; however, higher viscosities complicate atomization. The Air-Core-Liquid-Ring (ACLR) nozzle presents a promising approach, as it enables atomization of viscous feeds at low pressures (
