Title (EN) COOLING PROCESS AND APPARATUS
(FR) PROCEDE ET APPAREIL DE REFROIDISSEMENT
Abstract:
(EN) Material to be frozen is subjected to a cooling process which involves the application of sound waves, such as ultrasound. The invention has particular application in the frozen food products as margarine, chocolate and ice cream but may also be applied to freeze drying and cryopreservation processes. The material being frozen may also be subjected to a cooling regimen which efficiently removes the latent heat of freezing, for example by increasing the heat extraction rate when the latent heat of freezing is being given up. The invention may permit shorter freezing times and/or improved viability of the frozen or solid product.
(FR) On soumet un matériau devant être congelé à un procédé de refroidissement qui consiste à appliquer des ondes sonores, telles que des ultrasons. L'invention s'applique notamment aux produits alimentaires congelés tels que la margarine, le chocolat et les glaces, mais peut également s'appliquer aux procédés de lyophilisation et de cryoconservation. On peut également soumettre le matériau en cours de congélation à un régime de refroidissement qui élimine efficacement la chaleur latente de congélation, par exemple en augmentant la vitesse de l'extraction de chaleur lorsque la chaleur latente de congélation se libère. L'invention peut permettre des temps de congélation réduits et/ou une viabilité améliorée du produit congelé ou solide.
