[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an agricultural and marine product processing system, specifically, a shelf having a plurality of storage units capable of storing containers capable of ventilation from the front part to the back part is provided in a refrigerator,
A curtain-shaped body is provided to be openable and closable on the front opening of the storage unit,
In the curtain-like body, in its closed state, a ventilation opening is formed opposite to the front surface of the container stored in the storage portion,
Ventilation means for supplying adjusted air to the front surface area of the curtain-shaped body in the refrigerator, and for sucking air from the back side of each shelf of the storage unit is provided, and the adjusted air is supplied from a vent of the curtain-shaped body. The present invention relates to an agricultural and marine product processing system configured to pass through each of the storage units and process a processed product in a container stored in each of the storage units.
[0002]
[Prior art]
Such an agricultural and marine product processing system is provided with a curtain-shaped body openably and closably provided at a front opening of a storage unit, and a ventilation port provided in the curtain-shaped body in a closed state and opposed to a front surface of a container stored in the storage unit. With the curtain-shaped body closed, the adjustment air in the front surface area of the shelf is sucked into the storage portion so as to be concentrated on the front surface of the storage container from the ventilation port, and as many adjustments as possible The air is made to pass through the container to improve the processing efficiency of the processed material in the container.
Conventionally, the curtain-shaped member is provided so as to always contact the front surface of the container stored in the storage portion when the curtain-shaped member is closed (for example, see Japanese Patent Application Laid-Open No. 8-2009).
When the curtain is closed, the gap between the curtain and the front of the container is eliminated by removing the gap between the curtain and the front of the container. Thus, the flow rate of the processed material inside the container is further improved by suppressing the flow of the processed material inside the container.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional system, although the regulated air can be prevented from flowing around the container around the gap between the curtain-shaped body and the front surface of the container, the regulated air is opened and closed. Sometimes, since the curtain-shaped body is in contact with the front of the container, there is a problem that the curtain-shaped body cannot be opened and closed smoothly.
[0004]
The present invention has been made in view of the above circumstances, and an object of the present invention is to suppress the regulated air from flowing around the container around the gap between the curtain-shaped body and the front surface of the container. Another object of the present invention is to improve the operability of the opening / closing operation of the curtain-like body while further improving the processing efficiency of the processed material in the container.
[0005]
[Means for Solving the Problems]
According to the characteristic configuration of the first aspect, when the ventilation means is in the ventilation stop state and the curtain-shaped body is opened and closed, a gap is provided between the curtain-shaped body and the front surface of the container. The body can be opened and closed smoothly. Then, when the ventilation means is set to the ventilation operation state in a state in which the curtain-shaped body is closed, the curtain-shaped body is drawn to the shelf side and adheres to the front surface of the container by the adjusted air passing through the storage portion.
Therefore, while suppressing the regulated air from flowing around the container through the gap between the curtain-shaped body and the front surface of the container to further improve the processing efficiency of the processed material in the container, The operability of opening and closing the curtain-shaped body can be improved.
Further, the processing capacity of the system can be further improved by improving the processing efficiency of the processed material in the container.
[0006]
Incidentally, the opening / closing operation of the curtain-shaped body is performed, for example, for putting a container into and out of the storage unit. When the curtain-shaped body is opened / closed, there is no need to allow adjustment air to pass through the storage unit, and Since the ventilation is stopped, the space is opened between the curtain and the front surface of the container. On the other hand, when processing the processed material in the container stored in the storage unit by passing the adjusted air through the storage unit, the curtain is closed, so that the curtain is placed on the front of the container. It will adhere.
Therefore, even if the characteristic configuration described in claim 1 is adopted, there is no adverse effect on the processing of the original processed product.
[0007]
According to the characteristic configuration of the second aspect, when the container is stored in the storage unit, the range of movement of the container toward the back of the storage unit is determined by the stopper. In other words, with a simple operation of merely storing the container in the storage portion while being positioned by the stopper, the space between the curtain-shaped body in the ventilation stopped state and the front surface of the container is changed to the curtain-shaped body when the ventilation operation state is established. It can be set to an appropriate value to allow it to be drawn to the shelf side and adhere to the front of the container.
Therefore, the storage operation for storing the container in the proper position of the storage unit can be efficiently performed, and the synergistic effect of the efficiency of the storage operation and the improvement of the processing efficiency of the processed material in the container is achieved. As a result, the processing capacity of the system can be further improved.
[0008]
According to the characteristic configuration of the third aspect, the vent hole is formed such that the portion facing the center portion of the front surface of the container allows air to flow more easily than the portion facing the peripheral portion of the front surface of the container. Is formed.
That is, since the ventilation resistance in the front-rear direction of the container is higher at the central portion than at the peripheral portion, the ventilation port is formed so that the portion facing the central portion of the front surface of the container is larger than the portion facing the peripheral portion of the front surface of the container. Also, by making the air easier to flow, the variation in the amount of air flow due to the location of the conditioned air flowing in the container is suppressed.
Therefore, the uniform processing property of the processed material in the container can be further improved.
[0009]
According to the characteristic configuration of the fourth aspect, since the curtain-shaped body is divided for each frontage of the plurality of storage units arranged in the horizontal direction, the curtain-shaped body is divided in the ventilation operation state of the ventilation means. Each drawn curtain portion is drawn to the shelf side, so that it is easily drawn to the shelf side and closely adheres to the front surface of the container.
Therefore, in the ventilation operation state of the ventilation means, the curtain-shaped body is drawn to the shelf side and can be in close contact with the front surface of the container. Can be made as wide as possible.
As a result, when the curtain-shaped body is opened and closed, the curtain-shaped body can be more reliably prevented from coming into contact with the container, so that the operability of the curtain-shaped body opening and closing operation can be further improved. Was.
[0010]
According to the characteristic configuration of the fifth aspect, the regulated air is blown out and supplied from the air supply guide path in a state of being diffused to the front surface area of the curtain-like body in the storage, and the air is sucked through the suction chamber by the suction fan. This allows the conditioned air to pass through each of the storage sections from the ventilation opening of the curtain.
Therefore, a difference in the amount of adjusted air ventilation between the storage units can be suppressed, so that a variation in the processing quality of the storage processing object depending on the storage unit position on the shelf can be suppressed, and the uniform processing performance of the system for the processing object. Can be further improved.
[0011]
According to the sixth aspect of the present invention, the suction chamber and the suction fan for sucking air from the back side of the shelf into the storage section are separately provided for each of the plurality of storage sections in the shelf, and these individual suction sections are provided. Since air is independently suctioned into each storage unit by the chamber and the suction fan, even if there is a slight difference in the ventilation resistance of these storage units (mainly, the ventilation resistance due to the storage processing object), the suction fan is caused by the resistance difference. Is concentrated on the storage sections with smaller airflow resistance, and the difference in the adjusted air flow from the shelf front area in each storage section can be more effectively suppressed.
[0012]
In addition, the air suctioned by the individual suction chambers and the suction fan is guided to the air conditioner in a merged state by the return air guide passage, adjusted by the air conditioner, and the adjusted air is sent to the supply air guide passage. The suction air from the chamber and the suction fan (that is, the used adjusted air) is short-circuited into each of the storage units in a state where there is a quantitative difference depending on the storage unit position on the shelf due to diffusion in the storage, and the intake air of each of the storage units. A quality difference can be reliably prevented by the return air guide passage.
Therefore, from these facts, it is possible to more effectively suppress the variation in the processing quality of the stored processed product due to the storage unit position on the shelf, and it is possible to further improve the uniform processing performance of the system for the processed product.
[0013]
Moreover, as a basic configuration of the system, the air adjusted by the air conditioning means is blown out and supplied from the air supply duct to the front area of the shelf, and the adjusted air is sucked from the front area of the shelf into each storage section of the shelf. The system configuration can be simplified in terms of the air path configuration and the system cost can be reduced compared to the case where the adjustment air supply duct is directly connected to each storage section of the shelf individually and directly. Can be.
[0014]

Are provided with dehumidifiers 16 and 17 for dehumidifying the room air in the machine room 13 as air conditioning means.
[0020]
Outside the processing chamber 1, two combustion-type hot air fans 19 are provided as air heating means for heating the outside air and supplying the heated outside air OA to the respective machine rooms 13 through the hot air duct 18 separately. In this air-conditioning configuration, the room air in each machine room 13 is sent out from one end of each machine room 13 to each air supply duct 7 by the air supply fan 20 from one end of each machine room 13 as processing adjustment air SA. The processed material W in the container 5 stored in each storage section 2a of the shelf 2 is dried in the above-described processing mode.
[0021]
That is, basically, the air RA (that is, used adjusted air) sucked by the individual suction chambers 8 and the suction fans 9 from the respective storage portions 2a of the processing shelf 2 is returned to the return air chamber 10 as a return air guide passage. The air is guided to the machine room 13 in a merged state via the air conditioner, adjusted by dehumidifiers 16 and 17 as air conditioning means, and the adjusted air SA is sent out to the air supply duct 7 as an air supply and air introduction path.

[0025]
That is, with this communication port configuration, while reducing the required processing air volume of the auto-roll type dust filter 21 as the air purifying means, the dust RA in the return air chamber 10 is used to reduce the inflow air RA into the machine chamber 13. The dust removal process is performed efficiently, and the amount of air flowing into the machine room 13 (that is, the amount of air circulating between the machine room 13 and the shelf 2) is ensured by the upper and lower communication ports 11 and 12.
[0026]
Further, a part of the receiving air RA of each return air chamber 10 is also discharged to the outside of the processing chamber 1 by the exhaust fan 24 through the exhaust duct 23 serving as a dust exhaust passage, also serving as ventilation in the chamber. The exhaust and the dust removal by the dust filter 21 keep the concentration of dust in the processing chamber 1 at an allowable level with respect to the generation of dust from the stored processing object W.
[0027]
The container 5 for accommodating the processing objects W in an accumulated state has a ventilation structure in which four surfaces (five surfaces including a bottom surface in some cases) of a front surface, a back surface, and both lateral surfaces are formed of a mesh so as to allow the adjusted air SA to pass therethrough.

The supply / discharge switching device 41 is switched to the air supply state by opening the on-off valve V1 and the on-off valve V4 and closing the on-off valve V2 and the on-off valve V3, and switches the on-off valve V1 and the on-off valve V4. The exhaust state is switched by closing the valve and opening the on-off valve V2 and the on-off valve V3.
[0033]
Furthermore, on the front surface of each storage shelf 2, a curtain-like body 28 that can be opened and closed to close the front opening of each storage part 2 a is provided, and in this curtain-like body 28, the container 5 is attached to each storage part 2 a. A vent hole 29 having a porous structure is formed so as to be opposed to the front surface of each container 5 in a state where the container 28 is stored and the curtain 28 is closed.
[0034]
As shown in FIG. 6, when the curtain 28 is closed, as shown in FIG. 6, when ventilation is stopped by the ventilation unit T, the curtain 28 is opened so as to be spaced apart from the front surface of the container 5 stored in the storage section 2a. As shown in (2), when the ventilation means T is in the ventilation operation state, the ventilation means T is provided so as to be drawn toward the shelf side and closely contact the front surface of the container 5. When the curtain-shaped body 28 is provided so as to be spaced apart from the front surface of the container 5 when the ventilation is stopped and to be brought into close contact with the front side of the container 5 in the ventilation operation state, the curtain-shaped body 28 in the ventilation stopped state is provided. The distance between the container 28 and the front surface of the container 5 is set based on the flow rate and flow rate of the adjusted air SA, but is preferably set to, for example, about 50 mm.
[0035]
As shown in FIG. 11, the ventilation holes 29 are formed in a slit shape along the vertical direction, and five of the slit-shaped ventilation holes 29 are formed side by side so as to face the front surface of each container 5. . Further, of the five slit-shaped vents 29, the one facing the central part of the front surface of the container 5 has its width larger than the width of the one facing the peripheral part of the front surface of the container 5. Thus, the air is made to flow more easily than the one facing the peripheral portion.
[0036]
As shown in FIG. 10, with respect to the curtain 28, the horizontal core members 30 are attached to the main sheet member 28a (the sheet member having the ventilation holes 29) at appropriate intervals in the closed state. Then, the opening / closing operation cordage 31 is connected to the lowermost core material 30 through a guide ring 32 attached to each core material 30, and this cordage 31 is connected to the power take-up device 33 at the upper part of the processing shelf. As shown in FIG. 10 (b), the curtain-like body 28 is opened in a folded state in which the core material becomes a fold, and is stored in the upper end of the processing shelf 2 in the folded state. In this open state, the operation of loading / unloading the processing object storage container 5 with respect to each storage section 2a of the processing shelf 2 is performed.
[0037]
When the work container 5 is put into and taken out of each storage section 2a of the processing shelf 2, the suction fan 8, the air supply fan 20, the communication port fan 22, the exhaust fan 24, and the like are stopped to stop the ventilation, The curtain 28 is opened and operated. At this time, as shown in FIG. 6, the curtain 28 hangs down by its own weight, and a space is provided between the curtain 28 and the container 5. 5, so that the curtain 28 can be opened smoothly. Then, with the curtain-shaped body 28 opened, the transported machine 6 sequentially removes the processed containers 5 from the storage sections 2a as described above, and sequentially transfers the unprocessed containers 5 to the empty storage sections 2a. Entry / exit work to be stored in a state of contact with is repeatedly performed. Then, when the unprocessed container 5 to be processed is stored, the curtain 28 is closed and the ventilation is stopped. At this time, the space between the curtain 28 and the container 5 is opened. Since the curtain 28 does not catch on the processing shelf 2 or the container 5, the curtain 28 can be closed smoothly.
[0038]
When the curtain 28 is closed, the supply / discharge switching device 41 is switched to the air supply state, and the sealing fan 42 is operated. Then, as shown in FIG. 7, the four expansion / contraction sections 27 of each storage section 2a expand, so that the gap between the back surface of the container 5 stored in each storage section 2a and the rim of the suction port 8a is The four expansion / contraction portions 27 are closed by expansion.
Then, the suction fan 8, the air supply fan 20, the communication port fan 22, the exhaust fan 24, and the like are operated so as to be in the ventilation operation state, and the processing of the stored product W with the adjusted air SA is performed as described above.
As shown in FIG. 7, the curtain-like body 28 is drawn toward the shelf by the flow of the conditioned air SA, and is brought into close contact with the front surface of the container 5.
In a state where the curtain 28 is in close contact with the front surface of the container 5, the adjusted air SA supplied to the front surface area of the shelf is sucked from the ventilation holes 29 into the respective storage portions 2a so as to concentrate on the front surface of the container 5.
Therefore, since the curtain 28 is in close contact with the front surface of the container 5, the adjusted air SA flows through the gap between the curtain 28 and the front surface of the container 5, bypassing the periphery of the container 5. Is prevented.
Further, since the gap between the back surface of the container 5 stored in each storage section 2a and the rim of the suction port 8a is closed by the expansion of the four expansion / contraction sections 27, the adjusted air SA is The suction chamber 8 is prevented from being sucked into the suction chamber 8 from the gap between the back surface of the container 5 and the rim of the suction port 8a while bypassing the surroundings.
Furthermore, since the width of the slit-shaped ventilation port 29 facing the center portion of the front surface of the container 5 is larger than the width of the ventilation port 29 facing the peripheral portion of the front surface of the container 5, Although the ventilation resistance in the front-rear direction of the container 5 is higher in the central part than in the peripheral part, variation due to the location of the conditioned air SA flowing in the container 5 is suppressed.
[0039]
When the predetermined processing by the ventilation of the adjusted air SA is completed, the suction fan 8, the air supply fan 20, the communication port fan 22, the exhaust fan 24, and the like are stopped to stop the ventilation, and the supply / discharge switching device 41 is operated. The state is switched to the exhaust state. Then, as shown in FIG. 6, the curtain-shaped body 28 hangs away from the front surface of the container 5 with its own weight, leaving a space between the curtain-shaped body 28 and the front surface of the container 5. Shrink.
Then, the curtain-shaped member 28 is opened and operated. However, as described above, since the space is provided between the curtain-shaped member 28 and the container 5, the curtain-shaped member 28 can be opened smoothly.
[0040]
In other words, while the high processing efficiency is ensured by the forced ventilation of the adjusted air SA, the functions of the expansion / contraction section 27 and the curtain member 28 forming the ventilation port form the suction chamber 8 and the suction fan 9 for each storage section 2a individually. In combination with the arrangement, and also by preventing the used conditioning air RA from diffusing inside the refrigerator by the air guide by the return air chamber 10, the processing object W in the processing shelf 1 can be uniformly processed.
[0041]
Further, the suction air RA from each suction chamber 8 and the suction fan 9 is discharged downward into the return air chamber 10 by an elbow duct 34 connected to the discharge side of each suction fan 9, whereby the partition 14 by the discharge air is generated. In addition to preventing flapping, it suppresses the soaring of dust contained in the discharge wind.
[0042]
[Another embodiment]
Next, another embodiment will be described.
(A) The specific configuration of the vent 29 formed in the curtain 28 is not limited to the configuration exemplified in the above embodiment.
For example, a plurality of slit-shaped vents 29 extending along the horizontal direction may be provided in the vertical direction so as to face the front surface of each container 5.
Alternatively, one spiral vent 29 may be provided such that the center is located at the center of the front surface of each container 5.
Alternatively, one rectangular or circular vent 29 may be provided at the front of each container 5 so as to face the container.
[0043]
The vent hole 29 is not limited to a porous structure such as a net structure, and may be a simple opening.
[0044]
The vent hole 29 has a specific configuration for allowing air to flow more easily at a portion facing the center portion of the front surface of the container 5 than at a portion facing the peripheral edge portion of the front surface of the container 5. In the porous structure forming 29, the opening ratio of the portion facing the central portion of the front surface of the container 5 is larger than the opening ratio of the portion facing the peripheral portion of the front surface of the container 5. Is also good.
[0045]
(B) In the above embodiment, the case where the curtain-like body 28 is formed as a single-sheet structure over the entire surface of the shelf front portion in the closed state is illustrated, but instead, as shown in FIG. It is also possible to adopt a structure in which the front part of the storage part 2a is divided for each frontage, and each of the divided curtain portions can be opened and closed individually.
In this case, in the ventilation operation state, the curtain 28 is drawn to the shelf side for each divided curtain portion, so that it is easily drawn to the shelf side and closely adheres to the front surface of the container 5. Therefore, in the ventilation operation state, the curtain-shaped body 28 is drawn to the shelf side and can be in close contact with the front surface of the container 5, and the gap between the curtain-shaped body 28 and the front surface of the container 5 in the ventilation stopped state. The spacing can be made as wide as possible.
Further, since only the curtain portion corresponding to the area where the container 5 to be taken in and out is stored can be opened and closed, the opening and closing operation can be performed quickly. In addition, since the curtain portion corresponding to the area where the container 5 not to be taken in and out is stored is not unnecessarily opened, it is possible to suppress a change in the atmosphere in that area.
[0046]
Alternatively, the curtain-shaped body 28 may be divided at each frontage of the storage section 2a, and all the divided curtain portions may be simultaneously opened and closed.
Further, a structure may be employed in which only the main sheet material 28a is divided for each frontage of the storage section 2a.
[0047]
(C) Instead of the structure in which the curtain-like body 28 is opened by being pulled upward as in the above-described embodiment, a structure in which the curtain-like body 28 is moved in the lateral direction and opened may be used.
[0048]
(D) When the container 5 is stored in the storage section 2a by the transfer device 6, even if the storage posture of the container 5 and the storage position in the front-back direction are slightly varied, the container 5 is stored in the storage section 2a in the ventilation stop state. In a state where the space is opened between the front surface of the container 5 and the curtain-shaped body 28, in the ventilation operation state, the curtain-shaped body 28 can be drawn toward the shelf side and can be in close contact with the front surface of the container 5. Further, the gap between the back surface of the container 5 and the rim of the suction port 8a can be closed by the expansion state of the expansion / contraction section 27 and the flexibility of the sponge-like rubber 38. Therefore, the stopper 35 is omitted in the above embodiment. You may. In this case, the cost can be reduced.
[0049]
(E) It is preferable to provide an actuator such as a cylinder for moving the stopper 35 in the front-rear direction, since operability for setting the range of movement of the container 5 to the back of the storage section can be improved.
When the container 5 having a common length in the front-rear direction is used, it is preferable that the stopper 35 be fixedly provided at a predetermined position because cost can be reduced.
[0050]
(F) The specific configuration for closing the gap between the back surface of the container 5 stored in the storage section 2a and the edge of the suction port 8a for sucking air from the storage section 2a by the suction chamber 8 is as described in the above embodiment. In place of the expansion / contraction portion 27 as shown in FIG. 13, for example, as shown in FIG. 13, the rear portion of the container 5 is brought into contact with the storage of the container 5 so that the space between the container rear portion and the edge of the suction port 8a is airtight. An elastic packing 43 made of rubber or the like may be attached to the edge of the suction port 8a.
Further, as shown in FIG. 14, the expandable and contractible sealing joint duct 44 attached to the edge of the suction port 8a is extended by a suitable driving means 45 such as a cylinder, and the packing of the sealing joint duct 44 is performed. A structure in which the lip portion is pressed against the back surface of the storage container 5 may be employed.
[0051]
(G) In the above-described embodiment, the case where the suction chamber 8 and the suction fan 9 are separately provided in each storage unit 2a is illustrated. However, the arrangement of the suction chamber 8 and the suction fan 9 in each storage unit 2a. Can be variously changed.
For example, a common suction chamber 8 and a common suction fan 9 may be provided for all the storage units 2a in one vertical line of the processing shelf 2 or all the storage units 2a in one horizontal line of the processing rack 2, A common suction chamber 8 and a common suction fan 9 may be provided for all the storage sections 2a of the individual processing shelves 2.
[0052]
(H) The specific configuration of the ventilation means T that supplies the adjustment air to the front area of the curtain 28 in the processing chamber and sucks air from the back side of each shelf of the storage section 2a is exemplified in the above embodiment. It is not limited to the configuration.
For example, the suction chamber 8 may be omitted and air may be sucked by the suction fan 9 through the opening on the back surface of each storage section 2a.
[0053]
(I) When the adjusted air SA is forcibly passed from the front side of the container to the inside of the storage container 5 (container storing the processing object W) in each storage unit 2a of the processing shelf 2 by the individual suction chamber 8 and the suction fan 9. In addition, the upper surface of the group of processed objects in these containers 5 is covered with a drop lid-like wind shield made of a sheet material, a plate material, or the like, so that the adjusted air suction from the front surface of the container into the inside of the container is more accurately performed. The efficiency and uniformity of the processing may be further improved.
[0054]
(G) The processed product W may be any agricultural or marine product such as onion, potato, fruit, or seaweed or seafood, and the processing content of the processed product W is not limited to drying. Cooling, heating or humidification, or a combination thereof. The air-conditioning means for adjusting the suction air RA guided in the merged state by the return air guide passage is not limited to a dehumidifier, but may be an air cooler, an air heater, a humidifier, or a combination thereof. What is necessary is just to select according to the processing content of W.
[0055]
(V) In implementing the invention described in each claim, various structural changes can be made in terms of structure and method within the scope described in each claim.
