La présente invention concerne un dispositif de refroidissement rapide des aliments emballés sous vide, par immersion dans de 11 eau glacée. The present invention relates to a device for rapidly cooling vacuum-packed food by immersion in ice water.

Les méthodes modernes de préparation des aliments permettent la cuisson sous emballages passés au vide de plats cuisinés ou préparés à l'avance. Modern methods of food preparation allow cooking in vacuum-packed packages of dishes cooked or prepared in advance.

Aussi longtemps que les techniques de cuisson alimentaires ne permettaient pas la cuisson sous vide, le refroidissement des aliments ne pouvait autre réalisé que par contact avec de l'air froid fortement ventilé ou-non : procédé de convection air, ou en posant le produit sur une plaque, procédé de conduction. As long as food cooking techniques did not allow cooking under vacuum, the cooling of food could not be achieved other than by contact with cold air, strongly ventilated or not: air convection process, or by placing the product on a plate, conduction process.

Tous ces procédés sont de rendement moyen et sans aucune comparaison possible avec la conduction pat l'eau ou un autre liquide. La chaleur massique de l'eau étant nettement plus importante que celle de l1air, la quantité de fluide refroidisseur nécessaire est moins importante. All these processes are of average yield and without any possible comparison with conduction by water or another liquid. Since the specific heat of water is much higher than that of air, the quantity of coolant required is less.

Afin de respecter les normes d'hygiène et de securite' en vigueur, la chûte de temperature aliments préparés cuits à l'avance, doit être réalisée dans un délai un tres court. Le mode de cuisson sous vide permet de réaliser cette chute de temperature par immersion dans de leau glaces ctest à dire voisinant le point de congelatione Le fait de plonger un produit chaud dans un liquide froid a pour consé- quence immediate par conduction d'augmenter lo température du liquide en abaissant la température du produite
Les problèmes poses par le refroidissement par immersion de produits alimentaires emballés sous vide sont les suivants
- réaliser la chute de température d'un produit sortant directement de cuisson, ctest à dire 70 à 100 , à une tem pérature à coeur égale ou inférieure à a80 dans le temps légal,
- le maintien de la température de lteau à un degré voisin du point de congélation sans l'atteindre afin d'éviter la congélation mdme en surface des produits à refroidir,
- le maintien de l'homogénéité de la température de leau dans tout le volume du liquide,
- le mode de mise en mouvement de la masse d'eau liquide,
- la non détérioration des emballages alimentaires.
In order to comply with the hygiene and safety standards in force, the temperature drop of prepared foods cooked in advance must be achieved within a very short time. The vacuum cooking mode makes it possible to achieve this temperature drop by immersion in ice water, that is to say near the freezing point. Immersing a hot product in cold liquid has the immediate consequence of conduction to increase lo liquid temperature by lowering the product temperature
The problems with immersion cooling of vacuum packed food products are as follows
- achieve a temperature drop for a product that comes directly from cooking, ie 70 to 100, at a core temperature equal to or less than a80 in legal time,
- maintaining the temperature of the water at a level close to the freezing point without reaching it in order to avoid even freezing on the surface of the products to be cooled,
- maintaining the homogeneity of the water temperature throughout the volume of the liquid,
- the mode of setting in motion of the mass of liquid water,
- non-deterioration of food packaging.

Le dispositif selon llinvention permet de résoudre la totalité des problèmes ci-dessus posés. The device according to the invention solves all of the above problems.
