Embodiment Construction

[0037] exist figure 1 , 2 The sterilization apparatus 10 is shown in and 3, as described at the outset, before the tube is formed, filled and transversely sealed, a roll 12 of packaging material (only in figure 1 and 2 shown in) through the sterilization device 10 to be sterilized. A roll 12 from a roll of packaging material (not shown) enters the apparatus 10 at an inlet 14 and exits the apparatus at an outlet 16 to enter a dryer (not shown).

[0038] The apparatus 10 includes a lower buffer tank 18 and an upper bath 20 . The upper edge of the side wall 22 of the surge tank 18 is connected to the left edge of the bottom wall 24 of the bath 20, forming a direct transition between the surge tank and the bath. The bottom wall 24 of the tub 20 is not disposed perpendicular to the side wall 22 of the tub, but instead slopes gradually downward to the side wall 22 for reasons that will become apparent from the ensuing description. The interior 26 of the buffer tank is substanti...

Abstract

An apparatus (10) and method for sterilizing rolls (12) of packaging material are provided. The apparatus includes a bath (20) through which the roll passes and a transfer system for transferring a germicidal fluid from a germicidal fluid supply (30) to the bath. The device is characterized in that the transfer system comprises a buffer tank (18) to which the sterilizing fluid is transferred from the supply source and a movable volume adjustment element (34) for transferring the sterilizing fluid from the buffer tank to the bath. At least a portion (36) of the volume adjustment element is arranged to be received in the surge tank and to act on the sterilizing fluid in the surge tank, whereby the volume of the sterilizing fluid in the bath is a function of the position of the volume adjustment element in the surge tank .

Description

technical field [0001] The present invention relates to an apparatus for sterilizing rolls of packaging material comprising a bath through which the rolls are to pass and a transfer system for delivering a sterilizing fluid from a sterilizing fluid supply to the bath. The invention also relates to a method for sterilizing a roll of packaging material comprising conveying a sterilizing fluid from a sterilizing fluid supply to a bath and passing the roll through the bath. Background technique [0002] In packaging technology, packages have long been used for packaging and transporting beverages, such as milk, fruit juices and other pourable products. Most of these packages are made of laminated packaging material comprising a core layer such as paper or cardboard, and a liquid-tight seal of thermoplastic material disposed at least on the side of the core layer forming the inside of the package. outer cladding. Sometimes the material also includes a gas barrier layer, for exa...
