    means for forming a partial vacuum in said chamber;

    means in said chamber for discharging water onto said produce to minimize water infiltration onto said produce and to allow said water to flow downwardly over said produce;

    means for cooling and condensing water vapor in said chamber;

    means for collecting condensed water vapor and for preventing said condensed water vapor from flowing directly onto said produce;

    means for subjecting said condensed water vapor to at least one member from the group consisting of ozone, peroxide and UV radiation to remove a majority of the biological contaminants from said condensed water vapor; and

    means for releasing said partial vacuum within said chamber to minimize damage to said produce and to minimize water dispersion onto said produce during said releasing.
