Abstract (en)
[origin: WO2009130206A2] A cooling tunnel comprises an insertion gate (23) for inserting articles to be cooled which are preferably stacked on pallets, an exit gate (24) for exiting articles, a plurality of subsequent treatment positions (21.1 to 21.x) for impinging the articles to be cooled with a cooling medium, especially cooling air, and a conveying device (30) for transporting the articles to be cooled from the insertion gate (23) to the exit gate (24), the conveying device (30) leading through the individual treatment positions (21.1 to 21.x). The conveying device (30) comprises a first section (31) which runs through a plurality of treatment positions and which extends from the insertion gate (23) to a position of return (33), a second section (32) which runs through a plurality of treatment positions and which extends from the point of return (33) to the exit gate (24), and a return section (34) which is arranged upstream of the exit gate (24) and which connects an exit-side region of the second section (32) to an insertion-side region of the first section (31) to optionally exit articles or continue cooling them. The cooling tunnel according to the invention allows a high throughput at variable set cooling times and while maintaining the same in a narrow tolerance range. The invention also relates to a method for operating a cooling tunnel or a pallet cooling system.
