TODAY'S PATENT - ELECTROSTATIC SPRAY CHILLING OF FOODSTUFFS

Food can be quickly cooled with an electrostatic spray chilling system. Food moves on a conveyor through a tunnel that is cold. For the chilling tunnel to cool the food, the primary airflow is cooled. As the food goes through the chilling tunnel, spray modules create sprays of electrostatically charged fluid and apply them to the food. The charged droplets of liquid are drawn to the ground food. The charged fluid droplets can be guided onto the food by secondary fans and air-guiding baffles. The secondary fans are set up to create sub-flows of the chilled primary air.
