Definitions

  • the subject invention relates to the controlled ripening of fresh produce, in general, and to the forced-air or pressure cooling of bananas, in particular.
  • the same devices and methods can also be successfully applied to other foods and non-food items which might benefit by controlled air and temperature applications.
  • Background Art It is a well-known fact to those involved in the industry of produce management that the market life of produce is a function of time and temperature; the degree of ripening and subsequent deterioration of fruits and vegetables is related directly to the duration and intensity of heat exposure. Thus, effective protection of the produce is dependant upon efficient means of temperature control from harvest through final distribution.
  • special ripening rooms, or chambers as they are sometimes referred, must be constructed.
  • several designs have been suggested, each having in common a floor, ceiling and front, rear and side walls. These rooms are of suitable dimensions to enclose two spaced rows of the palletized produce containers which, in some instances, are stacked in two or more tiers to maximize space.
  • U.S. Patent No. 4,824,685 to Bianco, issued April 25, 1989, teaches one such design.
  • a two-tiered chamber whereby the two rows are spaced apart from one another to define an interstitial volume between the rows which substantially forms a low-pressure plenum.
  • This is a commonly used configuration and is further provided with an interior false wall structure arranged within the chamber which supports an air- handling unit closely adjacent the ceiling of the chamber to provide a source of controlled pressurized air flow and a plurality of high performance exhaust blowers to draw air out of the low pressure plenum. In this manner, the above- described air pressure differential is created.
  • the fans are essentially a point source of air pressurization, given the larger dimensions of the room compared to the spacing of each individual fan within the air-handling unit. Accordingly, prior art designs with such air-handling units provide an uneven air flow through the palletized boxes which is dependent on a location of a particular palletized box in relation to the air-handling unit.
  • the pressure drop across the outside of the palletized boxes and the formed interstitial area, referred to as the low-pressure plenum would vary as a function of the distance of a particular box from the air-handling unit.
  • the subject invention more specifically relates to a substantially improved method for controlling the ripening environment of produce, such as fruits and vegetables and the like.
  • the disclosed invention provides a significant improvement by using a plurality of pressure-inducing fans placed around the peripheral area of the ripening room.
  • the present invention describes a structure which provides improved air flow sealing to provide a constant pressure differential as measured across the width of the palletized produce boxes.
  • the present invention substantially increases the control over the ripening process for a given amount of produce.
  • the ripening system of the invention generally comprises a cooling chamber having a floor and ceiling and front, rear and side walls being of suitable dimensions to enclose at least one multiple-tiered rows of unitized and palletized produce, such as fruits and vegetables.
  • unitized and palletized produce such as fruits and vegetables.
  • the two rows of palletized produce are spaced apart from one another to define an interstitial volume between the rows which substantially forms a low-pressure plenum. There is sufficient space within this low-pressure plenum to allow inspection and access of the produce by a worker.
  • the temperature control within the ripening room utilizes an air-handling unit which may be placed more liberally than those found in the prior art because of the lack of need of the interior false wall.
  • air-handling units which are situated along the longitudinal axis of the ripening room may be used, allowing for more even temperature distribution.
  • the air-handling unit is utilized to provide temperature control and, pursuant to the various different embodiments available, because of the improvements in the disclosed room, the air-handling unit may be placed at the end of the room in a singular location or distributed about the room either down the longitudinal axis or in other combinations, as will be more fully described in the detailed description to follow.
  • a further improvement in the disclosed invention is the incorporation of floating sealing strips used in conjunction with the shelf unit containing the plurality of pressurizing fans.
  • gasket material provides for greater improved uniformity of air flow through the produce. Sealing strips are also used in a vertical fashion to provide for sealing between the stacks of palletized boxes resulting in a reduction in air pressure loss between the pressure plenums which would otherwise occur due to leakage between the boxes containing the produce, as opposed to directing the desired air flow through the boxes themselves.
  • a substantially sealed plenum is formed which provides for more uniform and more carefully-controlled air flow through the produce boxes.
  • the present invention allows a non-uniform number of pallets to be stacked on either side of the longitudinal axis of the ripening room without loss of effectiveness. For example, it would be possible to stack a longer length, and therefore larger number of pallets, on one side of the ripening room disclosed while having only one or two pallets on the opposite side and still provide for an even pressurization of the two outer high-pressure plenums.
  • the enclosed disclosure illustrates a slidable sealing door to be used to seal off the high-pressure plenum at any point desired, thereby creating what is essentially a floating end wall for the high-pressure plenum area.
  • the present disclosure also provides for a multi-tiered stack system which allows the same invention to be used with a multiple layer of two or more stacked pallets. Also, because of the unique design disclosed, it is not necessary that any air-handling unit be affixed to a false wall pursuant to the disclosures found in the prior art. Therefore, it is possible to use air-handling units that provide cooling or heating coils down the longitudinal axis of the room, preferably on the top of the room, providing for a more even temperature distribution throughout the room.

  • the room is conventional in its shape and design in that is it formed by a ceiling, floor and four walls.
  • the front wall is a slidable door panel.
  • the walls, front panel and ceiling are insulated to form a generally gas-tight chamber for the treatment of various produce, such as fruits and vegetables.
  • the overall dimensions of the ripening room are suitable to house one, two, or more one or multi-tiered rows of palletized produce and may be, by way of example only, approximately a height of 12 feet, a width of 12 feet, and a length of 42 feet.
  • the palletized produce 8 comprises a plurality of protective boxes 32 to unitize and protect the produce.
  • Protective boxes 32 are stacked on pallets 30 for easy handling during the insertion and removal of the produce load to and from the ripening room 2.
  • Each pallet 30 may be 40" x 48", with 48 protective boxes 32 stacked thereon.
  • each of the protective boxes 32 include side openings 34 which line up with the similar openings in the adjacent boxes on a particular palletized stack 8.
  • the openings 34 facilitate air flow through the boxes 32 in that the commonality of location of openings 34 and boxes 32 provide for continuity from the side of pallet stack 8 adjacent to an outer wall to the inner space defined between two rows of palletized produce, as will be more fully described.
  • the two rows of pallet stacks 8 form an interstitial volume between the two rows of the palletized stack 8.
  • the high-pressure air space 16 can be seen in FIG. 3 to be formed by an area defined by side wall 40 and one edge of pallet stack 8.
  • the lower boundary of the high-pressure air space 16 is defined by curb 28 and the upper end is defined by the peripheral fan shelf 12.
  • fans 10 by operating in a direction providing for an increase in pressure from top to bottom which provides air flow into space 16, there would be a pressure gradient from the ambient room area, defined as the low-pressure plenum or space 18, and air space 16.
  • the fluid within this high-pressure area 16 would normally seek to equalize its pressure by flowing to a lower pressure area 18 if it is provided unrestricted flow.
  • such pressure equalization path is across the stack 8 through the box side openings 34 located on boxes 32.
  • the fluid air in the preferred embodiment
  • the fluid moving as described would eventually communicate with fan 10 at the intake or low pressure end, and be recirculated by continuously moving from the high- pressure space 16 to low-pressure space 18, thereby allowing a continuous flow of air through the protective boxes 32.
  • high- and low-pressure spaces creating pressure gradients across the stacked boxes containing produce have been developed, but in a non-uniform fashion.
  • a point-source pressurization system usually a series of fans at the end of one room attached to a false wall, the high- and low-pressure spaces created did not provide for uniform air flow across the length of the stacks of produce.
  • a variation of the disclosed invention provides a technique for allowing more uniform flow of air volume through produce boxes by varying the size of the plenums formed by the rows of stacked produce. Resistance to air flow in a returned closed-circuit air circulation system is related to the dimensions of the plenum introducing the air to and from the pressurizing fan system.
  • the fluid pressure across the protective boxes may be adjusted so as to equalize the air flow through the palletized boxes located at the opposite end of the point source fans, as opposed to the air flow closer to the fan location in which a wider plenum described by angled stacks of pallets provide for a slightly reduced pressure differential across the boxes located therein, ultimately allowing for an equal air flow volume through the palletized boxes located at the far end of a ripening room when compared to boxes located close in to the fans providing the pressurizing sources.
  • vent stripes to existing tarp covers and louvers in air handlers to increase the isolation between the high- pressure areas and low-pressure areas within the ripening rooms. Air leakage and back flow through both the air-handling fans and tarps used in the existing art can be minimized through the use of the methods disclosed in the present invention.
  • This method of ripening room configuration is beneficial in retrofitting existing rooms. It can be appreciated that the air flow would be in reverse of that shown in FIG. 16 in ripening rooms of the existing art in that the fan within the air handler shown would be supplying air flow in the opposite direction.
  • seal 24 provides a means to improve the air flow through the boxes 32, as well as prevent air flow leakage from the high- to low-pressure areas.
  • seal 24 is a continuous strip of pliable pvc material running the length of room 2, affixed at the top to shelf 12. It can be seen from FIGS. 11 and 12 that seal 24 prevents air flow from traveling over the boxes 32 since the top of the pallet stack 8 does not normally reach the height of shelf 12.
  • seal 24 is held firmly against box 32 located at the top of stack 8 immediately adjacent to seal 24. It is important to note that seal 24 should extend downward from shelf 12 only to the extent necessary to cover the side of the top boxes on stack 8, as shown in FIGS. 11 and 12, so that the side openings 34 within the top box are sealed from air flow. This is to prevent the low resistance air flow path presented by the openings in the top boxes from exhausting a large volume of air, thereby reducing the pressure within space 16 enough to provide an uneven air flow across the lower boxes in stack 8.
  • the sealing means for the top area of top boxes can be of an adjustable type so as to roll or unroll the horizontal gasket air seal 24 to allow adjustment as to the number of box openings which are covered by the seal.
  • vertical and removable seal 26 is illustrated in detail in FIGS. 10 and 11. This removable strip is used to seal the vertical end of the high pressure air space 16 which is present in the preferred embodiment of room 2. As can be seen from the figures, the vertical seal 26 fits snugly between shelf 12 and curb 28. Further, the longitudinal ends of seal 26 fit between the outer wall of room 2 and the edge of the stack 8. Since a tight air seal requires a snug fit providing for little or no fluid leakage, it will be appreciated that a gasket-like material must be applied about the peripheral of seal 26.
  • seal 26 may be force-fitted and friction-held in the area provided such as to cause a pressure seal at the end of air space 16. It can be seen that the slidable seal 26 fits on the outer edge of horizontal gasket air seal 24, thereby assuring a firm and proper fit between protective boxes 32 located in pallet stack 8. In the normal course of operation, the protective boxes 32 do not always fit vertically or sit square or true on the pallet 30.
  • the friction-fit seal 26 is pliable enough to cause the gasket edging to fit within any irregularities in the size or location of boxes 32 in stack 8. It will also be appreciated that the gasket material deforms in an outward direction when pressure is applied to the handle shown in FIG. 10 and 11 attached to the face of seal 26. An inward, normally and firmly applied force to seal 26 in its intended resting location will cause the gasket material to be bowed in the outward direction, thereby causing a hysteresis effect in the force necessary to withdraw the seal 26. Accordingly, seal 26 is fairly effortless to install in position, but requires considerable force to withdraw, thereby assuring that the pressurization of area 16 does not cause a blow-out of seal 26.
  • FIG. 12 it can be appreciated that the frame-like rack shown parallel to stack 8 can be adjusted by running along the longitudinal axis of room 2 on the track.
  • the seal 26, which pivots upon a heel affixing it to an upper and lower track located at the curb 28, seal 26 can be rotated to be friction-fit against boxes 32 on stack 8.
  • the frame would be wider than required to simply fill the space between the outer wall and the pallet stack 8. In such a fashion, the frame seal 26 would be open in the inward direction, away from the direction of the free end of high pressure space 16.
  • seal 26 attempts to expand, thereby pressing the edge of seal 26 in contact with pallet stack 8 causing a firm fit.
  • the frame-like device used for seal 26 shown in FIG. 12 is likewise covered with pvc material affixed in a bow-like fashion along the peripheral edge of seal 26 allowing a firm fit where it contacts the boxes 32.
  • the frame is likewise located on the outer edge of horizontal seal 24, thereby assuring that the fit against the top box 32 is equally firm and fluid tight.
  • the ripening room 2 may be configured such that air handler 4 can be used to introduce fluid pressurization into high pressure area 16 through manifold 20.
  • the manifold 20 may consist of a singular manifold on each side of room 2 which would pressurize the entire length of area 16.
  • manifold 20 it is possible to develop manifold 20 in a fashion which would allow it to be divided into two or more ducts, thereby introducing pressurized fluid in area 16 at more than one location in each of the high pressure air spaces 16.
  • the present advantage is that it is possible to utilize the improvement disclosed by the present invention by retro-fitting existing rooms that may have air-handling units which can be adapted to provide for the air flow in the ripening process such as described earlier.
  • the basic configuration in general, provides for introduction of pressurized fluid within air space 16 regardless of the source of the pressurization. Pressurization may be by use of peripheral fans as earlier disclosed or the introduction of pressurized fluid through a pressurization source external of the fan shelf 12 as shown in the earlier figures. Though not disclosed specifically in the figures, one could appreciate that it is possible to integrate the air-handling units, particularly as configured in FIGS.
  • the ripening room can be configured such that there are multiple high pressure air spaces and that they may consist or be configured in the middle of a multi-isled ripening room allowing for at least three, and ultimately an indefinite number, of pallet stacks 8 to be located in a particular room.
  • a large, warehouse-like ripening room may conceivably be comprised of many rows of stacks 8 situated between areas 16 formed in multiple parallel rows. Even as disclosed in FIG.
  • FIG. 19 Yet another improvement for the sealing means utilized in the present invention are shown in FIG. 19.
  • the horizontal gasket air seal 24 shown in the earlier figures can be modified to allow for an adjustable seal which contains a rolling mechanism to be drawn down across the appropriate edge of protective box 32 such as to function as an effective air seal with an adjustable length.
  • the construction of rolling seal 50 is much like that of a vertical rolling blind commonly found in window treatments. Rolling seal end weight 54 allows the seal 50 to remain in position even though it is not fixed to protective box 32.
  • seal 50 As in the earlier-described invention, the air flow through the boxes creates pressure against the seal 50 holding it firmly in position. It is also possible to use seal 50 in conventional ripening room design since weight 54 can be sufficient enough to maintain the position of rolling seal 50, even though the air flow is reversed as traveling from the center of the room toward the outer peripheral walls. In like fashion, the existing designs of ripening rooms may be improved utilizing top seal flap 52. It would be appreciated from FIG. 19 that seal 52 may be affixed to shelf 12 or any other convenient location such as to allow a seal to be created which takes the place of exiting tarp designs in the existing art.
