Abstract

L'invention concerne des procédés et des systèmes associés à l'emballage alimentaire. Un plateau d'emballage d'aliments peut comprendre une couche de support façonnée pour former une pluralité de compartiments interconnectés. Chaque compartiment peut comprendre une pluralité de surfaces différentes configurées pour entrer en contact avec différentes surfaces d'un produit alimentaire lorsqu'elles sont placées à l'intérieur de chaque compartiment. Le plateau peut également comprendre une couche d'absorption d'énergie ayant un matériau différent de celui de la couche de support. La couche d'absorption d'énergie peut être couplée à une partie de la couche de support formant l'intérieur d'un ou plusieurs compartiments de la pluralité de compartiments interconnectés. La couche d'absorption d'énergie peut transférer de la chaleur directement vers l'extérieur du produit alimentaire. Chaque compartiment peut être séparé d'un compartiment adjacent par au moins une partie de la couche d'absorption d'énergie de telle sorte que des surfaces adjacentes de produits alimentaires adjacents reçoivent de la chaleur transférée depuis la couche d'absorption d'énergie.
