Title
(EN) SPRAY-TYPE STERILIZER APPARATUS AND STERILIZING METHOD
(FR) STERILISATEUR A PULVERISATION ET PROCEDE DE STERILISATION
Abstract
(EN)
A spray-type sterilizer apparatus and a sterilizing method for keeping a high sanitary level of products, minimizing dead space and simplifying the peripheral structure. Stacks of trays (2) placed horizontally are contained in a rotary container (3) rotatably supported in a sterilizer tank (1) (Fig.7(a)). After a medium supplying opening (42a) is tightly joined to an inlet opening (25), hot water is supplied to the inlet opening (25) and sprayed through a spray nozzle (23) to heat-sterilize products on the trays (2). Then, cool water is sprayed from the spray nozzle (23) to cool the products before the rotary container (3) is turned until an inclination angle of the trays exceeds 90°. The rotary container (3) is then reversely turned to be restored to the vertical position (Fig. 7(b)). After that, a hot air supplying opening (37a) is tightly joined to the inlet opening (25) above, the hot air is supplied to dry the products.
(FR)
L'invention concerne un stérilisateur à pulvérisation et un procédé de stérilisation permettant de maintenir des produits à un haut niveau de pureté, tout en minimisant l'espace mort et en simplifiant la structure périphérique. Des piles de plateaux (2) placés horizontalement sont contenues dans un caisson (3) monté rotatif dans un réservoir (1) de stérilisation (figure 7(a)). Après raccordement d'un orifice d'alimentation (42a) et d'un orifice d'admission (25), de l'eau chaude est conduite jusqu'audit orifice d'admission (25) et pulvérisée par l'intermédiaire d'une buse de pulvérisation (23) pour stériliser par la chaleur des produits se trouvant sur les plateaux (2). Ensuite, de l'eau froide est pulvérisée par l'intermédiaire de ladite buse de pulvérisation (23) pour refroidir les produits avant que le caisson (3) rotatif ait tourné jusqu'à ce que l'angle d'inclinaison des plateaux dépassent 90°. Le caisson rotatif (3) est ensuite soumis à une rotation en sens inverse pour revenir à la position verticale (figure 7(b)). Ensuite, un orifice (37a) d'alimentation en air chaud est raccordé, de façon étanche, à l'orifice d'admission (25) susmentionné, et de l'air chaud est amené jusqu'au caisson pour sécher les produits s'y trouvant.
