Abstract: A produce chamber (1) is provided to subject produce in a crate (7) to a controlled atmosphere. The chamber (1) has at least one inflatable/deflatable balloon seal structure (15) for sealingly engaging with a side wall of a produce crate (7) which has at least one opening (13) in a side wall (11) thereof. The balloon seal structure (15) has at least one discharge opening (19) that aligns with the at least one crate opening (13). Crates (7) with produce therein can be loaded in the chamber (1) with the balloon seal structure (15) deflated. The balloon seal structure (15) can then be inflated and controlled atmosphere allowed to circulate through the balloon seal structure (15) and discharged from the opening (19) and through the crate opening (13) to expose the produce to a controlled atmosphere.

Abstract: An air handling heat exchanger humidifying apparatus (1) is provided with a humidifying cell (13) of a self supporting sheet like body with closely spaced air openings therein. Air is moved through the apparatus (1) so it passes through the openings in the humidifying cell (13). A humidifying liquid is deposited onto the body surfaces of the cell between adjacent openings. As the air moves through the openings it collects the humidifying liquid from the surfaces of the cell (13). The humidifying liquid can be cooled. The air then exits the apparatus (1) and can be used for cooling produce or other product. The cell (13) can be an expanded mesh with the openings having a somewhat diamond shape. The cell (13) body can be corrugated to assist in humidifying liquid retention.
