Process and apparatus for producing a controlled atmosphere in a partitioned container for preserving fresh vegetable food products.

摘要

The various compartments (2a-2c) of the preserving container are fed with controlled atmosphere sequentially by a first permeator (81, 82) supplying a controlled atmosphere with an oxygen content of approximately 2% for the phase of charging the compartment, then by another separator (6) supplying a controlled atmosphere with an oxygen content not exceeding 1% for a long-term preserving phase. The separators are typically of the type with a membrane and are fed by a common compression set (9), and the oxygen contents of the gases supplied are regulated by downstream flow restrictors (12, 13).
