Abstract
The aseptic packaging installation comprises a bench under a ceiling, a line of machines mounted on the bench in a packaging zone subjected to a sterile laminar flow traveling vertically from the ceiling at a rate adapted to establish a first pressure in the packaging zone that is higher than a surrounding pressure, an intervention zone adjacent to the packaging zone, and subjected to a one-way flow of clean air travelling vertically from the ceiling of the intervention zone at a rate that is adapted to establish a second pressure in the intervention zone that is lower than the first pressure but higher than the surrounding pressure.

An aseptic packaging installation comprising a bench under a ceiling and a line of machines mounted on the bench in a packaging zone subjected to a sterile laminar flow of filtered air traveling vertically from the ceiling at a rate adapted to establish a first pressure in the packaging zone that is higher than a surrounding pressure, and an intervention zone extending on at least one side of the packaging zone, the intervention zone being subjected to an one-way flow of filtered air travelling vertically from the ceiling of the intervention zone at a rate that is adapted to establish a second pressure in the intervention zone that is lower than the first pressure but higher than the surrounding pressure and is at a temperature permitting access to the packaging zone without interrupting operation of the installation.
An aseptic packaging installation comprising a bench under a ceiling and a line of machines mounted on the bench in a packaging zone subjected to a sterile laminar flow of filtered air traveling vertically from the ceiling at a rate adapted to establish a first pressure in the packaging zone that is higher than a surrounding pressure, an intervention zone extending on at least one side of the packaging zone, the intervention zone being subjected to a one-way flow of filtered air travelling vertically from the ceiling of the intervention zone at a rate that is adapted to establish a second pressure in the intervention zone that is lower than the first pressure but higher than the surrounding pressure and is at a temperature permitting access to the packaging zone without interrupting operation of the installation;
- wherein ready access to the packaging zone is provided without interrupting operation of the aseptic packaging installation with direct, uninterrupted physical access being provided from ambient environment to the packaging zone.
An aseptic packaging installation comprising a bench under a ceiling and a line of machines mounted on the bench in a packaging zone subjected to a sterile laminar flow of filtered air traveling vertically from the ceiling at a rate adapted to establish a first pressure in the packaging zone that is higher than a surrounding pressure, an intervention zone extending on at least one side of the packaging zone, the intervention zone being subjected to a one-way flow of filtered air travelling vertically from the ceiling of the intervention zone at a rate that is adapted to establish a second pressure in the intervention zone that is lower than the first pressure but higher than the surrounding pressure and is at a temperature permitting access to the packaging zone without interrupting operation of the aseptic packaging installation;
- wherein ready access to the packaging zone is provided without interrupting operation with an operator being able to touch within the packaging zone while remaining outside the aseptic packaging installation.
