Title (EN) CRYOGENIC EXHAUST CONTROL SYSTEM AND FREEZER HAVING SAME
(FR) SYSTÈME DE RÉGULATION D’ÉCHAPPEMENT CRYOGÉNIQUE ET CONGÉLATEUR COMPORTANT CELUI-CI
Abstract:
(EN) A freezer for a food product, includes a housing having an internal space with a processing atmosphere for reducing a temperature of the food product; and a pressure balance apparatus in communication with the processing atmosphere to restrict atmosphere external to the freezer from reaching the internal space, the pressure balance apparatus comprising at least one sensor exposed to the processing atmosphere for generating a first signal indicating an amount of oxygen (O2) sensed at the internal space, and a blower disposed to direct a pressurized flow of the processing atmosphere to the internal space responsive to the first signal. A related method is also provided.
(FR) Selon la présente invention, un congélateur pour un produit alimentaire comprend un boîtier ayant un espace interne avec une atmosphère de traitement pour réduire une température du produit alimentaire ; et un appareil d'équilibrage de pression en communication avec l'atmosphère de traitement pour limiter l’entrée de l'atmosphère externe au congélateur dans l'espace interne, l'appareil d'équilibrage de pression comprenant au moins un capteur exposé à l'atmosphère de traitement pour générer un premier signal indiquant une quantité d'oxygène (O2) détectée au niveau de l'espace interne, et une soufflante disposée de façon à diriger un écoulement sous pression de l'atmosphère de traitement vers l'espace interne en réponse au premier signal. L’invention concerne en outre un procédé associé.
