ABSTRACT:
The different compartments of the preserving vessel are sequentially supplied with a controlled atmosphere by means of a first permeator providing a controlled atmosphere with an oxygen content of about 2% for the step of loading the compartment, then by means of an another separator providing a controlled atmosphere with an oxygen content which does not exceed 1% for a phase of extended conservation. The separators are typically of the type with a membrane and are supplied through a group of common compression, and the oxygen contents of the gases which are provided are controlled by means of flow limiters located downstream.
