Abstract
(EN)
The invention allows cool rooms or sea containers designed for frozen goods to handle produce requiring more precisely controlled temperatures and conditions, e.g. vegetables and fruits requiring temperatures in the chilling range and often also needing control or modification of the atmosphere. Each load of produce (100) (e.g. of pallet size) is held in the sea container or cool room but is sealed from the air of the refrigerated environment by, for example, a plastics bag (56). The atmosphere within the bag is then circulated by a fan (12) (or by convection currents from a heating element) so as to pass through the load and around it via ducts (30) provided adjacent the bag (56). Heat exchange (50) between the circulating gas and the refrigerated environment, via the plastics film, serves to cool the load. However if cooling is excessive a heating element can be used to raise the temperature of the circulating atmosphere. Gas composition of the atmosphere can be controlled by scrubbing, flushing, etc. via pipes from a central unit or at each load individually or by choosing semi-permeable plastic for the sealing bags.

La présente invention permet à des chambres froides ou à des conteneurs maritimes conçus pour les marchandises surgelées d'être utilisés pour des produits alimentaires nécessitant un contrôle plus précis des conditions de température et d'ambiance. C'est le cas, par exemple des fruits et légumes qui exigent des températures dans la plage de températures de réfrigération et un contrôle ou une modification de l'atmosphère. Chaque chargement de produit alimentaire (100), de la taille d'une palette par exemple, est conservé dans le conteneur maritime ou la chambre froide, mais est isolé de l'air ambiant réfrigéré, par exemple, au moyen d'un sac de plastique (56). L'atmosphère est mise en mouvement à l'intérieur du sac au moyen d'un ventilateur (12), ou grâce aux courants de convection créés par un élément chauffant, de façon à passer au travers et autour du chargement grâce à des conduits (30) adjacents au sac (56). L'échange thermique (50) via la pellicule plastique entre le gaz en circulation et l'air ambiant réfrigéré, permet de refroidir le chargement. Toutefois, si le refroidissement est excessif, il est possible de mettre en service un élément chauffant pour relever la température de l'atmosphère en circulation. Le contrôle de la composition du gaz de l'atmosphère peut se faire par lavage, rinçage, etc. au moyen de tuyaux provenant d'un organe central, ou bien individuellement au niveau de chaque chargement, ou bien encore en choisissant un plastique semi-perméable pour les sacs d'isolement étanche.
