Aseptic packaging installation having aseptic buffer zones

Abstract

An aseptic packaging installation in individual containers, comprising a stand on which there is mounted an enclosure ( 3 ) that has a floor ( 4 ) with an overhead ceiling ( 6 ) and that receives at least one rotatable platform ( 7 ) in a packaging zone (Z 1 ) subjected to a sterile laminar stream flowing vertically from the ceiling of the packaging zone at a rate that is adapted to establish in the packaging zone a first pressure (P 1 ) that is greater than the surrounding pressure, the installation being characterized in that the enclosure is provided with laminar stream exhaust means for removing the laminar stream from the packaging zone via a buffer zone extending between the packaging zone and the floor.
