An electrostatic spray chilling system is configured to rapidly cool foodstuffs. A conveyor traverses foodstuffs through a chilling tunnel. A chilled primary airflow is provided to the chilling tunnel to cool the foodstuffs. As the foodstuff is traversed through the chilling tunnel, spray modules generate and apply sprays of electrostatically charged fluid onto the foodstuff. The charged fluid droplets are attracted to the grounded foodstuff. The charged fluid droplets can be guided onto the foodstuff by secondary fans, configured to generate subflows of the chilled primary air, and by air guiding baffles.
