Process and equipment for the direct aging of fresh produce

The ripening room for directional maturation of the crop includes a chamber defined by a ceiling, a socket and a number of sides that connect the ceiling to the substrate. The chamber can accommodate a crop of two spaced-apart boxes, thus defining an intermediate air space. Each row of boxes is positioned adjacent to the wall to create a side space.

The ripening room also includes an air control system between the side air space and the intermediate air space for air transfer and temperature control of the transmitted air. The side air space and the intermediate airspace are generally closed, \ t

to prevent airflow between them, except for the airflow through the air control system and the box openings. The air control system directs air from the intermediate air space to the side air space over a period of time to create a low pressure space in the intermediate air space and a high pressure space in the side air space, such as the difference between low and high pressure airflow through the box openings from the side space to the intermediate air space into the intermediate air space. forces. The air control system is capable of reversing the direction of air flow in another time period to reduce the temperature change between the crops.

Process and equipment for the direct aging of fresh produce

Field of the Invention

The present invention relates to fresh fruits, in particular fresh fruit, e.g. Process and apparatus for guided banana aging.

Current state of the art

Bananas and other fresh produce are transported from the place of production to the processing unit, where they are placed in specially designed ripening rooms. These ripening rooms are equipped with insulated, gas-proof side and roof panels and include an air control unit to control the circulation and temperature of the air in the ripening room. In this way, the ripening of the fresh crop can be controlled according to a predetermined schedule so that the fruit is sufficiently mature when scheduled for direct sale to the seller. In the ripening rooms, ethylene gas can be sprayed at specified intervals to allow further control of the ripening of the crop. The use of ripening rooms thus facilitates the delivery of the crop to the direct seller, without the need for delivery time, which would be required by the natural ripening process of the fruit.

The use of ripening rooms eliminates the need for ripening or aging. slowing down problems that may arise due to changing conditions during crop transportation. U.S. Patent Nos. 4,824,685 and 5,373,780 disclose matrices in which the crop is packed in uniform conveying units, which are made up of separate protective boxes and are stacked on pallets. The pallet-placed crop is placed in ripening rooms that consist of a suitably sized socket (floor), roof (ceiling), front, rear and side walls to accommodate two rows of spaced pallets. The two rows are positioned so that there is a defined airspace between the rows. Sufficient space is provided for the crop and ceiling on the pallet. between the chamber wall to create an airspace above and beside the crop. The end of the space between and above the two rows of pallets is sealed so that the intermediate airspace is completely insulated from the air above and next to the crop. At the opposite end of the space between the rows, fans are disposed to extract air from the intermediate air space, thereby creating a differential pressure between the insulated intermediate air space and the air space above and next to the crop.

Air is fed into the air by an air handling unit. Due to the pressure difference between the airspace and the intermediate air space, the air is forced to flow through the opening on the side of the boxes, so that it circulates between the crops placed therein and passes into the low-pressure intermediate space from which the fans are driven out. In this way, forced airflow within the crop is created in the chamber. The temperature and flow rate of air introduced into the chamber can be varied by means of the air handling unit to direct the ripening of the crop.

Object and essence of the invention

It is an object of the present invention to provide a temperature controlled airflow in the ripening room, which generally comprises: · · · · ·.

it keeps at a constant temperature, which means that as a result of the temperature-controlled air flow, the temperature change in the whole crop is reduced to a minimum.

Another object of the present invention is that the maturing space, whether fully or partially filled, can rapidly and easily seal the air spaces contained therein so that it is large or large. create a low-pressure airspace to facilitate air flow within the crop load.

Another object of the invention is to provide a maturing room that can be easily ventilated by periodically replacing the air used in the room.

This can be accomplished with a ripening room that includes a chamber defined by a roof, a socket, a plurality of sidewalls connecting the roof to the socket. The chamber is designed to accommodate two rows of boxed crops where the rows are spaced apart to define an intermediate airspace. Each row is at a certain distance from one wall to define a side airspace. The ripening room has an air control system that transmits air between the intermediate and the side airspace and controls the air temperature. The side airspace and the intermediate airspace are generally closed to avoid airflow between them, except that provided by the air control system and the openings on the sides of the boxes. The air control system transmits air from the intermediate airspace to the side airspace, causing low pressure in the intermediate airspace over a period of time, high pressure in the airspace of the side, so that due to the difference between high and low pressure the air is forced to the page flows from the airspace to the intermediate air space through the openings of the boxes.

It is important for the invention that the air control system can turn the air flow in the opposite direction in another time period to reduce the temperature change in the crop • · · · · · · · · ·. In reverse airflow, the air control system transfers air from the side airspace to the intermediate air space, creating high pressure in the intermediate airspace, with low air pressure in the side air, causing the air to be forced into the air by the difference between high and low pressure. from the intermediate airspace to the side air through the openings of the boxes. By periodically changing the air flow, the temperature change within the crop can be virtually eliminated by the temperature-controlled air flow.

The ripening room includes two movable partitions, which can be independently positioned along the length of the ripening room to seal the front of the side airspace. The movable partition allows the side airspace to be sealed at the right place, depending on whether the matrix is fully or partially filled.

The ripening room is equipped with a ventilation system to ventilate it at the desired time.

Detailed Description (Example)

A mattress 10 according to the invention (Figures 1, 2, 3A and 3B) comprises a socket 12, a rear wall 14, a ceiling 16, two side walls 18, 20 and a front wall 22. The front panel 22 is provided with a pair of doors (not shown) that can be opened to allow access to the products in the mat. The sockets, walls, doors, and ceilings 12, 14, 16, 18, 20, and 22 are insulated and form a general · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · according to.

The ripening room 10 can optionally be placed on wheels (not shown) and used as a movable unit. Alternatively, it can be implemented as a fixed unit. The crop can be introduced into the chamber of the ripening room through the door of the front wall 22. from there on separate pallets. Each pallet contains a plurality of protective boxes 26, which are a unit and protects the crop. The protective boxes 26 are arranged on the pallets 28 in a bellows to facilitate loading and unloading into the mat. Each of the 28 pallets can be of standard size (40x48 inches) with a total of forty-eight protective boxes placed tightly adjacent to each other and placed over each other. Each of the protective boxes 26 has a side opening 30 which coincides with a similar opening of the adjacent protective box 26 to facilitate air flow through the protective boxes 26. The matrix according to the invention can be adjusted to different sizes depending on the desired maximum load capacity. The mattresses shown in the drawings 10 are sized so that (when fully loaded) two rows of pallets can be loaded with ten pallets in each row. The chamber of the ripening room is 2.85 m high, 2.82 m wide and 13 m long. As will be described below, the maturing room 10 does not need to be fully filled for operation, it can be operated with partial filling without any difficulty.

The matrix 10 is provided with five air control units 32 which are attached to the center of the ceiling between the side walls 18, 20. Each of the air control units 32 includes an air heater 34, which controls the air temperature, and a fan 36 centrally positioned to direct the air flow. If the ripening room is designed as a movable unit, instead of an electric motor, use a hydraulic motor to control the fans. Hydraulic motors emit less heat and require less space than electric motors. Each fan 36 of an air control unit 32 is arranged to provide air circulation for loads on two pallets 24. Each of the air control units 32 is connected to two chimneys 38 located between the opposite side walls 18, 20. On the ceiling 16, a lamp 40 is positioned between adjacent air control units 32 to provide light in the mattress if necessary. The length of the upper part of the chamber extends along two fixed flanks 42 (flue pipes), each parallel and adjacent to one of the side walls 18, 20. The side passages 42 are directed downwards from the ceiling 16 and are approximately 87.5 cm high. Approx. 20 cm. This gap forms part of the side air space 44 and, as described below, forms a large or low pressure space to aid airflow in the chamber. Each of the chimneys 38 out of the air control unit 32 is connected to an opening of one of the passageways 42 to allow air flow between the side air space 44 and the air control unit 32. In addition, the side compartments 44 are sealed by the outer sides of the crop placed on the pallets 24 on the two rows. As shown in FIG. and 3B. 1 to 3, the crop on the pallet 24 is arranged to fit the lower edge of the passage 42. The crop placed on the pallet 24 also fits into the metal bar 46 formed in the corner of the side wall of the matrix 10. (Metal pads 46 are used in the movable mats rather than in the concrete 46 rather in fixed mats.) The rear side of the crop at the back of the chamber is placed on the 24 pallets to the rear wall of the mat. To close the first ends of the 44 air space (later described in detail in · · · ·

4 to 10, two movable partitions 48 are provided. Thus, the side space is defined by the flights 42, the outside of the crop placed on the pallet 24, the pad 46, the side walls 18, 20, the rear wall 14 and the movable partition 48. As shown in FIG. and 3B. Fig. 10 shows that the crop of the two rows of pallets in the mattress room 10 is spaced apart. The space defines an intermediate space 50 between the two rows of pallets and directly above them. As will be explained below, the intermediate airspace 50 is a large or large space. forms a low-pressure airspace to facilitate air flow in the chamber.

During operation, the fans 36 of the air control unit 32 transmit the airflow in a controlled proportion between the intermediate air space 50 and the side air space 44. The fans 36 can transmit air in two directions, i.e., can be operated, as shown in Figure 3A, in one of the time periods from the intermediate airspace 50 to the side air space 44, and in the next period as described in FIG. Fig. 4a shows that air is supplied to the intermediate air space 50 from the side air space 44 in reverse. 3A. 1, the fans extract the air from the intermediate air space 50, thereby creating a low pressure therein and blowing air into the side air space 44, where high pressure is generated. This differential pressure causes the air from the air space 44 to pass through the openings 30 of the protective boxes 26 into the intermediate space between the two rows of crop placed on the pallet so that the fans 36 are then blown out again.

The side passage 42, the movable partition 48 and the pad 46 locks the sidewall 44 to allow air to flow through the openings 30 on the side of the protective boxes 26 and, consequently, between the boxes in the boxes.

· · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·

The differential pressure can thus be effectively utilized so that the air flow is uniform throughout the load. The flow of air allows the temperature of the crop to be controlled by controlling the air flow temperature with the help of the air control unit 32. At the same time, the flow of air allows the crop to be treated with ethylene or other gas in the ripening process. (A ethylene generator 52 is placed in the chamber of the ripening room to spray the ethylene gas at specific intervals.) If the cooler operates to cool cold air between the crop, the air flowing through the crop due to the difference between cold air and crop temperature warms up input and output port.

Thus, FIG. 1 and 2, the temperature of the crop placed near the side air space 44 will be lower than that of the intermediate airspace 50.

According to the present invention, this temperature difference can be reduced by periodically changing the direction of the air flow as shown in Fig. 3B by rotating the blades of the fans 36 in the opposite direction. In operation as shown in Fig. 3B, the fans 36 extract air from the side air space 44, thereby generating low pressure and blowing air into the intermediate space 50 where high pressure is generated. Due to the differential pressure, the air from the intermediate air space 50 flows through the protective boxes 26 into the side air space 44 to then be blown out again by the fans.

In this way, varying the direction of the air flow periodically, the crop can be kept at a generally uniform temperature.

If the matrix 10 is only partially saturated, the air control unit 32 must be operated only in the part where the crop is.

Thus, if a separate air control unit 32 is placed over the crops placed on the pallets 24, it can be switched off to reduce energy consumption.

Refer to 4-7. Figs. 4 and 6 show one of the movable partitions 48 which generally insulates the front of the side air space 24. Each of the movable partitions 48 includes an elongated (extended) rigid member 54. The edges of the closure 54 are flexible, with elastic strips or the like. 56 is provided with insulating flanges, so that it is generally insulated to the side walls 18, 20 and boxes 26 to prevent air flow along the sides of the partitions 48. Preferably, the closure 54 is aluminum, and the insulating flange 56 is preferably a neoprene sealant.

Each of the partitions 48 includes a wheel alignment 56 '(shown in detail in Figures 5A and 5B) rotatably connected to the upper edge of the closure 54. The wheel attachment 56 'is provided with four wheels 58 which can be moved along a rail 60 which is attached to the ceiling 16 of the mat. (The front view of the rail 60 is shown in FIG. 6.) The lower edge of each of the locking elements 54 extends a pin 62 which can be slid in a guide rail 64 located in the bar 46. Thus, the partition 48 becomes easily movable along the length of the matrix 10. The movable partitions 48 allow the front of the side air space 44 to be sealed quickly and easily in the full or partial saturation state of the mat. For example, in Figure 1, one row is placed on a fully saturated pallet, while the other is partially. The movable partition 48 can optionally be adjusted to the first member of the crop placed on the pallets 24 to seal any of the side space 44. 8A, 8B. and 8C. Figs. The partition 70 comprises a generally rigid closure 72 and an insulating flange 74 surrounding the wall 72. The flange 74 can be adjusted between a stretched and folded condition. In the stretch position, the flange 74 extends relative to the closure 72 to block the side air space 44 in isolation. In the collapsed state, the flange 74 moves inwardly relative to the closure 72 so that the partition 70 can be easily positioned along the length of the matrix 10.

The insulating flange 72 can be adjusted by means of a locking device between the stretched and folded condition which can be actuated manually. The locking device comprises a handle 76 which is pivotally rotatable at the center of the closure 72, a disc 78 secured to the handle 76, and four pegs 80 are pivotally secured to the disc 78. The other end of each of the connecting rods 80 is secured to one end of four bars 82. Each of the rods 82 may be slidable in nests 84 attached to the closure 72. The ends of the rods 82, which are remote from the center, are connected to one side of the closure 72 with a portion of the flange 74. 8A. Fig. 74 shows the flange 74 in a stretched state. The flange 74 can be folded so that the partition 70 can be moved so that the handle 76 is rotated counterclockwise as shown in FIG. 8B. and 8C. Fig. 1 is a graph. By rotating the handle 76, the rods 82 move toward the center of the closure 72, eliminating the tension of the flange 74. Thus, with manual operation, the flange 74 can be adjusted to the stretched and folded state.

Figures 9 and 10 show a further partition wall 90. The partition wall 90 is similar to FIG. 8A-C. Fig. 70 illustrates a partition wall 70 shown in FIG.

The locking device 92 (illustrated in detail in FIG. 10) comprises a handle, rotatably disposed at the center of the closure 72, two connectors 96 fixed to the handle 94 and four longitudinal bars 98, which are pivotally connected to the ends of the connectors 96. The other end of the bars 98 moves in a nest 84 in the middle of the edge of the closure 72 and is in communication with the flange 74.

The other adjacent ends of the bars 98, which are connected to the connectors 96, are eccentric with respect to the closure 72, so that when the handle 94 is rotated (clockwise in the figure), the ends of the bars 98 are adjacent to the wall. and the insulating flange 74 extends relative to the closure 72. When the handle 94 is rotated in the opposite direction, the adjacent ends of the bars 98 extend away from the center of the wall and the flange 74 closes. The locking device 92 thus allows the flange 74 to be adjusted to a stretched or folded position by hand operation.

During the operation of the 10 maturation rooms, the chamber gradually develops ethylene, carbondioxide and other gases. Accordingly, a venting system is provided in the chamber to occasionally replace the air in the room with fresh air. For long periods of operation, the ventilation system is operated twice a day for half an hour to provide adequate ventilation.

11-13. Figure 1 shows a ventilation system according to the invention which is particularly suitable for movable mats. The ventilation system comprises two channels, each along the length of the ripening room 10 in the hollow metal 46 located in the corners of the base and side wall of the matrix 10. One end of the channel is a perforated outlet 68 (FIG. 4) which opens into the intermediate air space 50. As illustrated in detail in FIG. 13, the other end of the channel extends into a vent aperture 110 on the rear wall 14 that opens to the open air. Another ventilation aperture 112 may also be placed on the rear wall 14, which allows airflow between the side air space 44 and the rear air. The ventilation openings 110 and 112 have a spring valve 114 (schematic drawing a

Fig. 13), which is closed when the 10 mattresses are used normally. but it can be opened to allow air flow through the ventilation openings 110, 112.

When the fans 36 of the matrix 10 are of the type 3A. Figure 2 shows a high pressure space in each side air space and low pressure in the intermediate air space. Accordingly, as shown in FIGS. Figure 110 shows that when the vents 110, 112 are open, the opening 112 functions as an inlet opening, allowing fresh air to be drawn into the intermediate low pressure space 50 (indicating airflow 116) and the opening 110 acts as an outlet opening to allow high pressure We release the air from the 44 side airspace (118 airflow).

When the fans 36 are operating in the matrix 10 in reverse i3B. Figure 110 shows the direction of the airflow) and the openings 110, 112 are open, the opening 110 is the input, the opening 112 is the outlet. 14 and 15 illustrate a matrix 120 with a ventilation system version that can be used in particular for a fixed matrix. The ventilation system is provided by an inlet vent 122, which is positioned on the ceiling 16 at the front of the mattress 120 and allows fresh air to flow into the chamber. when the ventilation opening 122 is open. There is also an outlet aperture 124 which is located at the back of the mattress 120 at the ceiling 16. The output silo opening 124 is provided with a fan 126 to be discharged at the end of the circuit.

Although the erlelotem shown in the drawings shows only single row pallet placement, the method of the present invention can be applied to multi-storey pallet placement. In multi-storey pallets, such as those described in U.S. Patent Nos. 5,373,780 and 4,824,685, a support frame or grid is provided to accommodate two or more rows of palletized crop, i.e. the amount of crop to be treated on a given floor area It can be increased. The support frame structure allows the crop placed on the pallet to be placed in two rows separated by space, and one or more pallets in the vertical direction. We leave space between the pallets placed vertically on each other to facilitate loading and unloading. A passageway similar to the passage 42 extends along the frame structure to insulate the spacing (line spacing) between the stacked pallets. This prevents direct air flow through the side airspace and the intermediate airspace through the vertical spacing

Although the present invention has been described with specific implementation conditions, numerous modifications and modifications may be proposed to one skilled in the art. The present invention is intended to encompass these changes and modifications and are within the scope of the claims.
