    摘要： The present invention relates to a device (1) in a filling machine, said filling machine comprising a filling pipe for supplying liquid food to the tube (27) of packaging material, a pipe (20) for supplying pressurized sterile air to the tube (27) of packaging material, and a gasket (26) for sealing against the tube (27) of packaging material and any pipes (20) inside the tube (27), for creating an overpressure in said tube (27). The device (1) further comprises a first pressure gauge (22) for measuring a first pressure (
    p
    1 ) inside the pipe (20) at a location upstream from the tube (27), means (22, 23; 28) for determining an air mass flow (
    m
    f ) in said pipe (20), and a control unit (30) for receiving the measured parameters (
    p
    1
    , m
    f ), where said control unit (30) is adapted to calculate the pressure (
    p
    t ) in said tube (27) based on the air mass flow (mf) and the first pressure (
    p
    1 ), according to a first pre-established relationship (R1).The invention also relates to a method being implemented by the device (1).

    摘要： The present invention relates to a sterilization chamber (1) for sterilizing a web (3) of packaging material passing through the sterilization chamber (1), comprising an air-distribution system and heating elements (13a, 13b) arranged to heat the web (3), and a fan (11a, 11b) is provided at an end of the sterilization chamber (1), for driving a circulating flow therein, and where a heater (13a, 13b) is arranged at the outlet of said fan (11a, 11b). A method of operating the sterilization chamber is also disclosed, comprising the steps of a) feeding a packaging material web (3) through a sterilizing agent bath, and then into a sterilization chamber (1), b) driving a gas flow inside said chamber (1) with a fan (11a; 11b), c) heating the air leaving the outlet of the fan (11a; 11b) with a heater (13a; 13b), and d) directing the flow from the outlet of the fan (11a; 11b) towards the packaging material web (3) and on towards the inlet of the fan (11a; 11b).
