Title
(EN) METHOD AND APPARATUS FOR THE PASTEURIZATION OF A CONTINUOUS LINE OF PRODUCTS
(FR) PROCEDE ET APPAREIL DE PASTEURISATION D'UNE CHAINE CONTINUE DE PRODUITS
Abstract
(EN)
The object of the method and the apparatus according to the invention is to reduce pumping effect as well as thermal energy during regeneration of heat between the individual zones (Z1, Z2, ..., Zn) in a tunnel pasteurizer, respectively to simplify the apparatus to the extent possible. This is accomplished in an apparatus of the kind, which makes use of at least a pair of conveyors (T1, T2), in that the pair of conveyors (T1, T2) are of equal length and extend in opposite directions, and that the water, which is sprinkled down over the products in a given zone of the cooling area (Z1 to Z3) of one conveyor (T1), continues sprinkling over the products which pass through the zone of the heating area (Z1-Z3) positioned adjacent to and at the same distance and the same direction from the center of the pasteurization area (Z4, Z5) of the other conveyor (T2). The products are heated respectively cooled by water which is sprinkled over the products and is recirculated, and the regeneration of heat is accomplished by a cross exchange crosswise of the apparatus by placing the two conveyors (T1, T2) one (T1) above the other (T2) and by having the water sprinkle down directly from the top conveyor (T1) to the bottom conveyor (T2).

L'objet du procédé, et l'appareil, de l'invention est de réduire l'effet de pompage ainsi que l'énergie thermique pendant la régénération de chaleur entre des zones individuelles (Z1, Z2, ..., Zn) dans un pasteurisateur à tunnel, respectivement, afin de simplifier autant que possible l'appareil. L'on a atteint cet objectif dans un appareil du type utilisant au moins une paire de convoyeurs (T1, T2) caractérisé en ce que la paire de convoyeurs (T1, T2) est d'une longueur égale et s'étend dans des directions opposées, et en ce que l'eau destinée à l'arrosage des produits dans une zone donnée de la partie de refroidissement (Z1, Z3) du convoyeur (T1) continue de se répandre sur les produits passant dans la zone de la partie de chauffage (Z1-Z3) adjacente au centre de la partie de pasteurisation (Z4, Z5) de l'autre convoyeur (T2), à une distance identique de celui-ci et dans la même direction. Les produits sont respectivement chauffés puis refroidis par de l'eau, laquelle est répandue sur les produits et est recirculée, la régénération de chaleur s'effectue par un échange croisé transversalement à l'appareil par mise en place des deux convoyeurs (T1, T2), un (T1) au dessus de l'autre (T2), et par aspersion d'eau vers le bas directement à partir du convoyeur supérieur (T1) sur le convoyeur inférieur (T2).
