  • the products are pasteurized in a regular progressing movement from an in- let to an outlet.

  • tunnel pasteurizers comprise a heating and a cooling area
  • a gradual heating and a gradual cooling is effected in order to avoid breakage of the containers of the products, these being normally glass bottles, at abrupt changes of temperature, and thereby at the same time a heat exchange between the heating and the cooling areas is utilized for regeneration of heat energy.
  • the heat transfer for contained products is normally carried out by spraying the containers with a heated fluid, preferably water, as the products are carried forward through the apparatus on a conveyor, the sprinkling water passing through the conveyor.

  • the temperature of the sprinkling water in the individual zone is adapted carefully according to the products, the lengths of the zones in the apparatus and the speed of the conveyor belt in order to ensure that the products receive the prescribed degree of pasteurization.

  • the water in the individual zones has a temperature, which depends on the distance of the individual zone from the center of the apparatus constituting the pasteurization area in the form of the zones Z4 and Z5 and so that the temperature in a zone is always lower than the temperature in a zone, which is located closer to the pasteurization area.
  • zones Z4 and Z5 as explained above are supplied with warm water having a tem ⁇ perature which corresponds to the temperature of pasteurization, the warm water being sprinkled down over the products on the bottom conveyor T2.

  • the sprinkling water in zone Z6 has thus during a heat exchange between the products on the two conveyors become cooled upon joining the colder products on the top con ⁇ veyor Tl.
  • the increased temperature for the products on the bottom conveyor T2 in the zones Zl to Z3 is correspondingly the result of the sprinkling water in these zones having been sprinkled over the warm products on the top conveyor Tl.
  • the source of heat which heats the water in the zones Z4 and Z4 as well as the remaining zones in the event of an imbalance is preferably a central source of heat.
  • imbalance will here refer to a condition during operation when the progression of temperature in one or more zones for some reason does not progress as planned, as a result of which warm or cold water must be supplied to the products in question.
  • the method in which the conveyors move in opposite directions with two conveyors, will require a new design for the feeding conveyors, which in some cases may appear to be a complication and in other cases to be a simplification, depending upon the layout of the lines of the external conveyors.

Abstract

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).
