Abstract

La présente invention concerne un congélateur pour la surfusion d'un objet contenu dans un emballage, le congélateur étant caractérisé en ce qu'il comprend : un corps comprenant une chambre de refroidissement ayant une pluralité d'étagères installées sur celle-ci, des objets contenus dans un emballage placés sur les étagères, et une porte pour ouvrir/fermer une surface latérale de la chambre de refroidissement ; un évaporateur disposé sur la partie supérieure de la chambre de refroidissement pour refroidir l'air à l'intérieur de la chambre de refroidissement ; un conduit de refroidissement destiné à contenir l'évaporateur ; un ventilateur de circulation d'air positionné en face de l'évaporateur dans le conduit de refroidissement pour fournir de l'air de la chambre de refroidissement à l'évaporateur ; un conduit d'alimentation en air froid relié au conduit de refroidissement pour entraîner l'air, qui a été refroidi au moyen de l'évaporateur à l'intérieur du conduit de refroidissement, vers le bas de la chambre de refroidissement ; une pluralité de conduits d'extension faisant saillie à partir du conduit d'alimentation en air froid à une pluralité d'emplacements dans la direction dans laquelle est positionnée la porte, permettant ainsi de fournir de l'air froid au-dessus des objets contenus dans un emballage placés sur les étagères, respectivement ; et un conduit inférieur s'étendant à partir d'une extrémité du conduit d'alimentation en air froid de façon à recouvrir le bas de la chambre de refroidissement, permettant ainsi de fournir une partie d'air froid, qui est fourni par le conduit d'alimentation en air froid, à un objet contenu dans un emballage placé sur sa partie supérieure. Par conséquent, l'installation du conduit inférieur et des conduits d'extension, qui évacuent de façon uniforme de l'air froid jusqu'à la partie avant sur laquelle est installée la porte du congélateur, maintient la température interne du congélateur de façon uniforme, permettant ainsi la surfusion des objets contenus dans un emballage de façon uniforme, et l'alimentation en air froid directement au-dessus des objets contenus dans un emballage au moyen des conduits d'extension raccourcit le temps nécessaire pour fournir de l'air froid, permettant ainsi d'améliorer l'efficacité de surfusion.
