  • the counter pressure required is increased with a higher filling temperature dec, ie the necessary filling pressure of the finished beverage correlates with the filling temperature resulting from the respective manufacturing or processing process.

  • the mixture of degassed water and syrup is usually cooled before its subsequent carbonation, since otherwise the latter would have to be operated with a relatively high pressure or energy input in the case of cooling after the carbonation. Since energy is introduced into the beverage during carbonation, which is ultimately reflected in the beverage by an increase in temperature, the mixture of degassed water and syrup is cooled to a temperature which is about 2 ° C. below the filling temperature.

With the two-stage cooling, the prerequisite for energetically favorable carbonation is created in the first stage and then in the second stage the carbonated finished beverage is specifically cooled to its filling temperature.

Abstract

L'invention concerne un procédé permettant de refroidir des boissons gazéifiées jusqu'à leur température de mise en contenants, selon lequel on mélange, selon un rapport de mélange prédéterminé, de l'eau dégazée (W) et du sirop (S), le mélange (W+S) est traité par gazéification (C) pour donner une boisson finie (G), et le mélange (W + S) ou au moins l'eau dégazée (W) sont refroidis. Ce procédé doit permettre d'obtenir, en ce qui concerne la capacité calorifique à installer, une solution plus économique que celle obtenue avec les procédés connus jusqu'ici. Cet objectif est atteint par le fait que, dans le cadre d'un transfert de chaleur en deux étapes (1; 1a, 1b) et à l'aide d'un seul agent frigorifique (K) ayant la même efficacité pour les deux étapes, l'eau dégazée (W) est, d'abord, au cours de la première étape (1a), refroidie jusqu'à une température intermédiaire ( theta WA) qui est supérieure à la température de mise en contenants ( theta GA) et, au cours de la seconde étape (1b) la boisson finie (G) est refroidie jusqu'à sa température de mise en contenants ( theta GA). Le dispositif permettant la mise en oeuvre du procédé présenté comporte, à cet effet, entre autres, un échangeur de chaleur à faisceaux de tubes (1) avec vaporisation directe d'un agent frigorifique (K), qui présente deux paquets de faisceaux de tubes (1a, 1b) séparés l'un de l'autre et contenus dans une enveloppe (1c) commune, et dans lequel le premier paquet de faisceaux de tubes (1a) est destiné à recevoir l'eau dégazée (W) et le second paquet de faisceaux de tubes (1b) est destiné à recevoir la boisson finie (G).
