Abstract
An impingement cooler or freezer includes at least one impingement section, having a plurality of channeling means defining apertures enabling cooling fluid impingement flow toward and onto objects on a conveyor and defining a channel through which the cooling fluid from the objects flows into a duct which carries the fluid to a unit that chills the fluid, and includes passage means which receives cooling fluid from said apertures and lets it enter the duct after having flowed toward and onto said objects, the fluid being impinged and recirculated by a fan.
