Abstract

Selon l'invention, un plateau comprenant des saillies peut stocker un produit, tel que de la viande. Les saillies peuvent s'étendre vers le haut ou vers le bas par rapport au plateau. Les saillies peuvent permettre au plateau d'être décalé par rapport à un autre plateau ou une autre surface. Les saillies peuvent permettre un écoulement d'air et, par conséquent, un écoulement d'oxygène à travers un film du plateau et dans le produit stocké à l'intérieur.
