(54) | A process for the vacuumized brimfilling of cans fashioned from aluminium alloy, tinned metal strip or other easily buckled material, and a device for the implementation of such a process |
(57) The process and the device relate to the art field of brim-filling cans in a vacuum,
with a liquid such as oil, in order to preserve perishable foodstuffs. The can (15)
is positioned in a sealed chamber (1) with its inside totally isolated so that different
negative pressure levels can be created at once in the can and in the chamber; the
vacuum generated in the chamber, which is of a lesser degree than that maintained
in the can, prevents the material of the can itself from buckling under pressure and
ensures aseptic filling conditions. |
