A produce-ripening room (1) has a pallet rack (8) designed to support one or more modular pairs of two loaded pallets (11) juxtaposed side-by-side with a select space between them for central distribution of conditioned atmosphere under pressure throughout produce crates (12) positioned on the pallets (11). The modular pairs of two loaded pallets (11) can be one-to-three tiers high, up to twelve tiers deep and as many tiers wide as desired stacked bin boxes may be substituted for the pallets. A top horizontal baffle (22) is positioned vertically above and extended from end-to-end over depth of the select space between the modular pairs of two loaded pallets (11) and seals (26, 27, 36, 37) are positioned on four sides of the select space to provide a central high-pressure plenum (25, 34) for a first embodiment. For a second embodiment, the top horizontal baffle (22) is extended over the entire pallet rack and valves (50) can be positioned at sides to create a chamber high-pressure central plenum (47) throughout the space occupied by stacked produce crates (12) in addition to central high-pressure plenums. A third embodiment omits the central high-pressure plenums and employs central pressure supply throughout the chamber plenum for a form of low-temperature pressure-processing of all types of produce in all types of crates. A closed-circuit color-television camera or optical sensor (58) and instrumentation (59) can provide remote observation and control.
