An apparatus for the continuous cold sterilization of a fluid (4) comprising at least one ultraviolet radiation source (2) and at least one duct (3) permeable to such radiation in which the fluid flows. The duct has a portion with helical shape (3a) around the ultraviolet radiation source (2) which is arranged in a chamber (1a) with walls having reflective surfaces. The distance between the walls and the helical portion is sufficient to allow an adequate circulation of air between them, whereby an excessive heating of the fluid is avoided. Moreover, at least the helical portion of the duct has an elliptical- shaped passage section (5) with major axis perpendicular to the irradiation direction to reduce the thickness of the fluid exposed to radiation and thus increase the treatment efficiency.

L'invention concerne un appareil destiné à la stérilisation continue à froid d'un fluide (4). L'appareil comprend au moins une source de rayonnement ultraviolet (2) et au moins une conduite (3) perméable audit rayonnement et dans laquelle le fluide s'écoule. La conduite comprend une partie de forme hélicoïdale (3a) disposée autour de la source de rayonnement ultraviolet (2) et ménagée dans une chambre (1a) dont les parois présentent des surfaces réfléchissantes. La distance entre les parois et la partie hélicoïdale est suffisante pour y assurer une circulation adéquate de l'air, ce qui évite un chauffage excessif du fluide. De plus, au moins la partie hélicoïdale de la conduite comporte une section de passage de forme elliptique (5) présentant un axe principal perpendiculaire au sens de l'irradiation, qui sert à réduire l'épaisseur du fluide exposée au rayonnement et à augmenter ainsi l'efficacité du traitement.
