Title
(EN) APPARATUS COMPRISING A HYGIENIC COOLING SYSTEM AND METHOD
(FR) APPAREIL COMPRENANT UN SYSTÈME DE REFROIDISSEMENT HYGIÉNIQUE ET PROCÉDÉ
Abstract
(EN) An apparatus for mixing a liquid or pasty product. The apparatus comprises a first housing part (11) and a second housing part (12) assembled together. The assembly of the first housing part (11) and the second housing (12) part forms • - a housing inner space (17) between an inlet (4) and an outlet (5), • - a cooling jacket (7) for circulation of a coolant fluid around the housing inner space (17), and • - a buffer jacket (9) for circulation of a clean fluid, the buffer jacket (9) being formed between the cooling jacket (7) and the housing inner space (17). The buffer jacket protects the mixed product from contamination by the coolant fluid. It also facilitates detection of leakage between the housing inner space and the buffer jacket. The invention also relates to a corresponding method.
(FR) L'invention concerne un appareil pour mélanger un produit liquide ou pâteux. L'appareil comprend une première partie de boîtier (11) et une seconde partie de boîtier (12) assemblées l'une à l'autre. L'ensemble de la première partie de boîtier (11) et le seconde partie du boîtier (12) forme • - un espace intérieur de logement (17) entre une entrée (4) et une sortie (5), • - une chemise de refroidissement (7) pour la circulation d'un fluide de refroidissement autour de l'espace interne du boîtier (17), et • - une chemise tampon (9) pour la circulation d'un fluide propre, la chemise tampon (9) étant formée entre la chemise de refroidissement (7) et l'espace intérieur de boîtier (17). La chemise tampon protège le produit mélangé contre la contamination par le fluide de refroidissement. Il facilite également la détection de fuite entre l'espace interne du boîtier et la chemise tampon. L'invention se rapporte également à un procédé correspondant.
