DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural and marine product processing system, and more particularly, to a shelf provided with a plurality of storage sections capable of storing a ventilable container extending from a front portion to a rear portion in a storage, A curtain-shaped body is provided to be openable and closable at a front opening of the storage part, and the curtain-shaped body is formed with a ventilation opening facing the front surface of the container stored in the storage part in a closed state thereof. And a ventilation means for supplying adjusted air to the front area of the curtain-shaped body in the refrigerator and for sucking air from the back side of each of the shelves of the storage section, so that the adjusted air is ventilated through the curtain-shaped body. The present invention relates to an agricultural and marine product processing system configured to process a processed product in a container stored in each of the storage sections by passing the storage section through each of the storage sections from a mouth.

[0002]

2. Description of the Related Art In such an agricultural and marine product processing system, a curtain is provided at the front opening of a storage section so as to be openable and closable, and the curtain is placed on the front of a container stored in the storage section in a closed state. By forming the opposed vents, in a state where the curtain-shaped body is closed, the adjusted air in the front surface area of the shelf is sucked from the vents into the storage portion so as to be concentrated on the front surface of the storage container. A large amount of conditioned air is allowed to pass through the inside of the container to improve the processing efficiency of the processed material in the container. Traditionally, curtains
In its closed state, it is provided so as to always contact the front surface of the container stored in the storage section (see, for example, 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 eliminating the gap between the curtain and the front of the container. In this case, the flow rate of the processed material in the container is further improved by suppressing the flow through the container around the periphery of the container.

[0003]

However, in the above-described conventional system, it is possible to prevent the conditioned air from flowing around the container around the gap between the curtain-shaped body and the front surface of the container. However, when the curtain-shaped body is opened and closed, there is a problem that the curtain-shaped body cannot be opened and closed smoothly because the curtain-shaped body is in contact with the front surface of the container.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to adjust air to flow around a container around a gap between a curtain-shaped body and the front of a container. The 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 processing object in the container by suppressing the above.

[0005]

According to the first aspect of the present invention, when the ventilation means is in a ventilation stopped state and the curtain-shaped body is opened and closed, the space between the curtain-shaped body and the front surface of the container is provided. Since the spaces are wide, the curtain can be opened and closed smoothly. Then, when the ventilation means is set in a ventilation operation state in a state where 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 conditioned air from flowing around the container by passing through the gap between the curtain-shaped body and the front surface of the container, the curtain-shaped The operability of opening and closing the body can be improved. Further, by improving the processing efficiency of the processed material in the container, the processing capacity of the system can be further improved.

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, it is necessary to allow air for adjustment to pass through the storage unit. Instead, since the ventilation means is in the ventilation stop state, at that time, there is an interval between the curtain-like body and the front surface of the container. On the other hand, when the processed air in the container stored in the storage unit is processed by passing the adjusted air through the storage unit, the curtain is closed. 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.

According to the second aspect of the present invention, 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 simply storing the container in the storage section with the container positioned by the stopper, the space between the curtain-shaped body and the front surface of the container in the ventilation stopped state,
In the ventilation operation state, the curtain-shaped body can be set to an appropriate value to allow the curtain-shaped body to be drawn to the shelf side and adhere to the front surface of the container. Therefore, it is possible to efficiently perform the storing operation for storing the container at an appropriate position in the storing section, and to achieve a synergistic effect of improving the efficiency of the storing operation and improving the processing efficiency of the processed material in the container. As a result, the processing capacity of the system can be further improved.

According to the third aspect of the present invention, in the vent, air flows more easily at the portion facing the center of the front surface of the container than at the portion facing the peripheral portion of the front surface of the container. It is formed so that it becomes. In other words, the ventilation resistance in the front-rear direction of the container is higher at the central portion than at the peripheral portion, 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 forming the air to be easy 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.

According to the fourth aspect of the present invention, since the curtain-shaped body is divided for each frontage of a plurality of storage portions arranged in a horizontal direction, the ventilation means is in a ventilation operation state.
Since the curtain-shaped body is drawn to the shelf side for each divided curtain portion, 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, it is possible to more reliably prevent the curtain-shaped body from contacting 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 duct in a state of being diffused to the front surface area of the curtain-like body in the refrigerator, and is sucked by the suction fan through the suction chamber. By the air suction, the conditioned air passes through each of the storage portions from the vent 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 system can uniformly process the processing object. Can be further improved.

According to the characteristic configuration of the present invention, a suction chamber and a 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. Since the air is suctioned independently for each storage unit by the individual suction chamber and 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 difference in the resistance is due to the difference. As a result, the suction action of the suction fan is concentrated on the storage sections having a small airflow resistance, so that the difference in the amount of regulated air from the front surface of the shelf in each storage section can be more effectively suppressed. .

Further, the air sucked by the individual suction chambers and the suction fan is guided to the air conditioner in a merged state by the return air guide path, adjusted by the air conditioner, and sent out to the supply air guide path. Thus, the suction air from the suction chamber and the suction fan (i.e., the used adjusted air) is short-circuited into the respective storage units in a state in which there is a quantitative difference depending on the position of the storage unit on the shelf due to diffusion in the storage, and the respective storage units It is possible to reliably prevent a difference in the quality of the intake air from being generated by the air guide 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 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.

Further, as a basic configuration of the system, the air adjusted by the air-conditioning means is blown out and supplied from the air supply guide to the front area of the shelf, and the adjusted air is supplied from the front area of the shelf to each of the shelves. The system is simpler in terms of air path configuration, and the system cost is lower than in the case where the adjusted air supply duct is directly connected individually to each storage section of the shelf, because the system takes the form of inhalation into the storage section. Can be

Further, on the front face of each storage shelf 2, there is provided a curtain-like body 28 which can be opened and closed to close the front opening of each storage part 2a. A ventilation port 29 having a porous structure is formed so as to be positioned opposite to the front surface of each container 5 in a state where the curtain-shaped body 28 is housed in the section 2a and closed.

As shown in FIG. 6, in the closed state of the curtain 28, when the ventilation means T stops the ventilation, the curtain-like body 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 FIG. 7, 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. The curtain 28
When the ventilation is stopped, the space between the front surface of the container 5 and the curtain-shaped body 28 in the ventilation stopped state is set to be close to the front surface of the container 5 by being drawn toward the shelf side in the ventilation operation state. Is set based on the flow rate and flow rate of the conditioned air SA,
For example, it is preferable to set it to about 50 mm.

As shown in FIG. 11, the ventilation port 29 has a slit shape extending in the vertical direction.
9 are formed side by side so as to face the front surface of each container 5. Further, of the five slit-shaped vent holes 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.

As shown in FIG. 10, in the closed state, the curtain-like body 28a is provided on the main sheet material 28a (the sheet material having the ventilation holes 29) spread over the entire front surface of the shelf at appropriate intervals in the vertical direction. Then, a cable 31 for opening and closing operation is connected to the lowermost core member 30 through a guide ring 32 attached to each core member 30. As shown in FIG. 10 (b), the curtain-shaped body 28 is opened in a folded state in which the core material becomes a fold by winding it upward by the take-up machine 33.
In the folded state, it is stored at the upper end of the processing shelf 2, and in this open state, the work for loading and unloading the processing object storage container 5 into and from each storage section 2 a of the processing shelf 2 is performed.

When the processing object storage container 5 is inserted into or removed from 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. Then, the curtain 28 is opened and operated. At this time, as shown in FIG.
Since the curtain 28 hangs down by its own weight and the space between the curtain 28 and the container 5 is wide, the curtain 28 does not catch on the processing shelf 2 or the container 5. 28 can be opened smoothly. Then, with the curtain-shaped body 28 opened,
As described above, the transfer machine 6 sequentially takes out the processed containers 5 in the respective storage sections 2a and sequentially stores the unprocessed containers 5 in the empty storage sections 2a in contact with the stoppers 35. Is repeatedly performed.
Then, when the unprocessed container 5 to be processed is stored, the curtain 28 is closed and operated.
Since the ventilation is stopped and there is a gap between the curtain 28 and the container 5, the curtain 28 does not catch on the processing shelf 2 or the container 5, so that the curtain 28 is closed smoothly. be able to.

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 portions 27 of each storage portion 2a expand, so that the gap between the back surface of the container 5 stored in each storage portion 2a and the rim of the suction port 8a is Four expansion / contraction portions 27
Is closed by the expansion of. 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 a ventilation operation state, and the processing of the housed 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. With the curtain-shaped body 28 in close contact with the front surface of the container 5, the adjusted air SA supplied to the front surface area of the shelf 5 is condensed from the ventilation port 29 to the front surface of the container 5 so as to concentrate on each storage unit 2.
a. 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 portion 2a and the rim of the suction port 8a is closed by the expansion of the four expansion / contraction portions 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 vent 29 facing the center of the front surface of the container 5 is larger than the width of the vent 29 facing the peripheral portion of the front 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, the variation due to the location of the conditioned air SA flowing in the container 5 is suppressed.

When the predetermined processing by the ventilation of the conditioned 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 is performed. The device 41 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 by its own weight in a state where an interval is provided between the curtain-shaped body 28 and the front surface of the container 5, and the expansion / contraction portion 27 of each storage portion 2a 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.

In other words, while the high processing efficiency is ensured by the forced ventilation of the conditioned air SA, these expansion and contraction sections 2
7. Due to the function of the vent-formed curtain 28, combined with the individual arrangement of the suction chamber 8 and the suction fan 9 for each storage section 2a, and the diffusion of the used conditioned air RA in the compartment by the air guide by the return air chamber 10. Is prevented, and the processing object W stored in the processing shelf 1 can be uniformly processed.

Each suction chamber 8 and suction fan 9
Is discharged downward into the return air chamber 10 by the elbow duct 34 connected to the discharge side of each suction fan 9, thereby preventing the partition 14 from flapping due to the discharge air and being included in the discharge air. Suppress the rising of dust.

[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 ventilation holes 29 extending along the horizontal direction may be provided in the vertical direction so as to face the front surface of each container 5.

A structure in which the lip portion is pressed against the back surface of the storage container 5 may be employed.

(G) In the above-described embodiment, the case where the suction chamber 8 and the suction fan 9 are individually provided for each storage section 2a has been exemplified. However, the suction chamber 8 and the suction fan 9 for each storage section 2a are provided. Can be variously changed. For example, a common suction chamber 8 and 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 are provided for all the storage units 2 a of the processing shelves 2.
May be provided.

(H) Curtain-like body 2 in processing chamber
The specific configuration of the ventilation means T that supplies the adjusted air to the front area of the storage unit 8 and suctions air from the back side of each shelf of the storage unit 2a is not limited to the configuration illustrated in the above embodiment. 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.

(I) The regulated air SA is forcibly passed from the front side of the container into the storage container 5 (container for storing the processed material W) in each storage section 2a of the processing shelf 2 by the individual suction chamber 8 and the suction fan 9. For this purpose, 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 regulated air can be further sucked into the inside of the container from the container front portion. It is also possible to achieve more efficient and uniform processing by appropriately.

(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 limited to drying. Instead, cooling, heating or humidification, or a combination thereof may be used. 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 the dehumidifier, but may be an air cooler, an air heater, a humidifier, or a combination thereof.
