A method for freezing a commodity includes a plurality of boxes arranged in two rows with a space formed therebetween. A plenum is formed between the two rows of boxes with the plurality of boxes being positioned side-by-side. Air is pulled through and/or around the plurality of boxes and through ventilation holes in the boxes and/or through spacers positioned underneath adjacent boxes and along a length of the space formed between the two rows. The air may be discharged upwardly, horizontally or downwardly therefrom. In addition, the air may be forced through the plenum, along the length of the space formed between the two rows and through ventilation holes in the boxes and/or through spacers positioned underneath adjacent boxes for evenly freezing a commodity positioned in the boxes.
