The invention relates to a method for conditioning the atmosphere in a storage chamber for organic harvested produce, characterized in that the storage chamber is allowed to form part of a system composed of the relevant storage chamber (1), at least two, and preferably three, gas separation modules (2), (3) and (4), which are located downstream of one another and are provided with N2/O2 separation membranes, at least one compressor (5) and at least one control valve (6), the compressor drawing in three streams (F1), (F2) and (F3), the first separation module yielding a permeate, which is removed from the system as stream (F4), and a retentate, which is fed to the second separation module, the second separation module yielding a retentate, which is fed to the third separation module, and a permeate, which is fed together with the permeate from the third separation module as stream to the compressor, and the retentate from the third separation module is fed via the control valve to the storage cheer.

A method for conditioning the atmosphere in a storage chamber containing organic harvested produce comprising the steps of: (a) storing organic harvested produce in a storage chamber under a first atmospheric condition; (b) drawing an atmospheric stream from the storage chamber; (c) drawing an air stream; (d) mixing said atmospheric stream and said air stream to provide a mixed stream; (e) feeding said mixed stream to a first separation module; (f) separating said mixed stream in said first separation module into a first permeate stream and a first retentate stream; (g) feeding said first retentate stream to a second separation module; (h) separating said first retentate stream in said second separation module into a second permeate stream and a second retentate stream; (i) feeding said second retentate stream to a third separation module; (j) separating said second retentate stream into a third permeate and a third retentate stream; and (k) passing said third retentate stream to said storage chamber so as to modify the first atmospheric condition.
