TECHNICAL FIELD OF THE INVENTION
The present invention relates to an agricultural and marine product processing system, and more specifically, blows out and supplies conditioned air to a front surface area of a shelf having a plurality of storage sections in a refrigerator in a state of being diffused from an air supply and ventilation path, and each of the storage sections. The present invention relates to an agricultural and marine product processing system for processing regulated products in each of the storage sections by sucking air from the storage section to the rear side of the shelf with a suction fan, thereby passing regulated air through each of the storage sections.
[0002]
[Prior art]
Conventionally, in this type of processing system, air is suctioned from each storage section of the shelf by a suction fan through a suction chamber provided on the rear side of the shelf, whereas the suction air (ie, used adjusted air) is suctioned. The air was released into the refrigerator by the fan function. In addition, as for the regulated air to be blown out in a state of being diffused from the air supply guideway to the front area of the shelf in the refrigerator, an air conditioner that adjusts the intake air by sucking air around the body in the refrigerator. The air conditioner is provided in the air conditioner, and the air-conditioner is connected to the base end of the air supply and air guide path, so that the air conditioned by the air conditioner is sent to the air supply and air guide path.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned conventional system, the air intake from the vicinity of the airframe in the refrigerator is adjusted by the air conditioner, and the adjusted air is sent out to the air supply and air duct connected to the air conditioner. The air volume of the conditioned air that is blown out from the air path and diffused to the front area of the shelf is limited to the permissible passing air volume of the air conditioner. It was difficult to supply conditioned air uniformly.
[0004]
Further, in this situation, since the used adjusted air sucked from each storage unit to the shelf rear side by the suction fan is released into the refrigerator, the used adjusted air is diffused in the refrigerator after the release, and the used air is released from the shelf. In a state where there is a quantitative difference depending on the position of the storage section, it is short-circuited into each storage section together with the adjusted air in the front area of the shelf, so that there is a qualitative difference in the intake air from the front area of the shelf in each storage section. As a result, there is a problem in that the processing quality of the storage processing object varies among the storage units on the shelf.
[0005]
In view of this situation, a main problem of the present invention is to solve the above problem effectively by rationalizing the wind guide configuration while adopting a simple system configuration as a whole.
[0006]
[Means for Solving the Problems]
[1] According to the first aspect of the present invention, the air sucked from each storage section of the shelf to the rear side of the shelf by the suction fan is guided to the air conditioning means by the return air guide passage, adjusted by the air conditioning means, and returned. A part of the suction air guided by the air guide passage is bypassed to the air conditioning means by the bypass air passage, and a mixture of the air adjusted by the air conditioning means and the bypass air by the bypass air passage is supplied as processing adjustment air. Since the air is sent to the air guide path, the suction air from the storage units by the suction fan (that is, the used adjusted air) is short-circuited to 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. It is possible to reliably prevent the quality of the intake air in each of the storage sections from being qualitatively inhaled by the air being guided by the return air guide passage.
[0007]
Then, in a state in which a large amount of air to be sent to the air supply guide air path is secured by the bypass by the bypass air path without being restricted by the allowable air flow amount in the air conditioner, and in a mixed state to the air supply air guide path. In a state where the delivered air is homogenized by the air delivery, a uniform and large air volume of the process adjusted air consisting of a mixture of the adjusted air by the air conditioning means and the bypass air by the bypass air passage is supplied from the supply air guide passage to the shelf. It can be blown out and supplied in a state where it is diffused to the front area, and as a result, compared with the conventional system, it is possible to effectively prevent the processing quality of the stored processed material from being varied among the storage units on the shelf, and the system can be effectively prevented. Can greatly improve the uniform processing property for the processed material.
[0008]
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 supplied from the front area of the shelf to each storage section of the shelf. Since the suction type is adopted, the system configuration can be simplified in terms of the air path configuration, and the system cost can be reduced compared to another type in which the adjustment air supply duct is directly connected individually to each storage section of the shelf. can do.
Further, a machine room for receiving the air sucked from each of the storage units by the suction fan in a merged state through the return air guide passage is formed in the compartment, and the machine room is provided with the air conditioning means as the air conditioning means. An air conditioner for adjusting the room air is provided, and in this configuration, the room air of the machine room is supplied and guided by the air in a state where the machine room is also used as the air guide path for the air conditioning means and the bypass air path. Since the air is sent to the path, the system configuration can be further simplified in terms of the air path configuration as compared with the case where the air guide path and the bypass air path for the air conditioning means are formed by dedicated ducts.
Further, since the air sucked by the suction fan from each of the storage units is received and processed in the machine room in a merged state via the return air guide passage, the plurality of storage units on the shelf are provided with an air conditioner as air conditioning means. , And a machine room for forming a partition in the compartment is shared, which makes it possible to further simplify the system configuration in terms of the arrangement of the air-conditioning means and the partition forming surface of the machine room in the compartment. Can be further reduced, and maintenance of the system (particularly, inspection and maintenance of the air conditioner) can be facilitated.
[0009]
[2] According to the second aspect of the present invention, in adopting a configuration in which air is sucked by a suction fan from each of the storage sections in the shelf via a suction chamber provided on the rear side of the shelf, the suction chamber and the suction fan are stored in the shelf. Since the air is independently suctioned into each storage unit by the individual suction chambers and the suction fans, the airflow resistance of these storage units (mainly the airflow resistance due to the storage processing object) is slightly increased. Even if there is a difference, due to the difference in resistance, the suction action of the suction fan is concentrated on the storage section having a small ventilation resistance, and the adjusted air flow from the front surface area of the shelf in each storage section. Large difference can be effectively suppressed, and thereby, the uniform processing performance of the system with respect to the processing object can be more effectively improved.
[0012]
[ 3 ] In the invention as set forth in claim 3 , a return air chamber for merging air sucked from each of the storage units by a suction fan by the suction fan is provided on the rear side of the shelf adjacent to the machine room. And a communication port for allowing air to flow from the return air chamber to the machine chamber is formed as a partition between the two chambers, and air for purifying air passing through the communication port is formed in the communication port. Since the purifying means is provided, the air purification by the air purifying means can improve the environment in the storage against dust and the like generated from the stored material in the storage unit, and can prevent dust from adhering to the air conditioner disposed in the machine room. The trouble caused can be effectively prevented.
[0013]
In addition, a return air chamber for joining the air sucked from each of the storage sections by the suction fan is formed on the shelf rear side in the compartment, and the suction air is merged from the return air chamber to the machine room through the communication port. In the configuration where the air is sucked in from each storage section of the shelf by individual suction fans, the air sucked by the suction fans is introduced into the machine room through a separate return air guide path such as a duct structure. The system configuration can be further simplified in terms of the air path configuration.
[0014]
[ 4 ] In the invention according to claim 4 , as the communication port, a lower communication port formed near the floor and an upper communication port formed near the ceiling are provided, and only the lower communication port among these communication ports is provided. Since air purifying means is provided, the air purifying means is reduced in size by reducing the required processing air volume of the air purifying means. By this means, the air can be efficiently purified, and the amount of air flowing into the machine room (that is, the amount of circulating air between the machine room and the shelf) can be largely secured by the upper and lower communication ports.
[0015]
[ 5 ] In the invention as set forth in claim 5 , since a dust guide path for discharging a part of the air received into the return air chamber to the outside of the refrigerator is provided, the air discharge by the dust guide path is provided. With the accompanying dust discharge, and by efficient dust discharge from the return air chamber where the dust concentration is highest in the air circulation system, and further by ventilation in the refrigerator by this air discharge, air purification by the air purifying means can be performed. Together, the interior environment can be more effectively improved.
[0016]
[ 6 ] In the invention according to claim 6 , since a transfer device is provided which moves between the loading / unloading section of the processing object storage container and the shelf and automatically puts the processing object storage container into and out of each of the storage sections. By using this transfer machine, containers can be easily put in and taken out of each of the storage sections of shelves, and the efficiency can increase the processing capacity of the system per unit period.
[0017]
In addition, the carrying-in part and the carrying-out part of the processing object storage container are arranged in a form close to each other, or in a form arranged apart from each other, or the carrying-in part and the carrying-out part are one carrying-in / out part. Any of the forms that also serve as the functions may be adopted.
[0018]
[ 7 ] In the invention according to claim 7 , since the air conditioning means is configured to be capable of dehumidifying the air guided by the return air guide passage, the air dehumidified by the air conditioning means passes through each storage section of the shelf. In this way, the stored processed product can be efficiently dried, and in this drying process, the processed product can be uniformly dried by exhibiting the high uniform processability as described above.
[0019]
[ 8 ] In the invention according to claim 8 , air heating means for heating the outside air is provided, and a mixture of the outside air heated by the air heating means, the air dehumidified by the air conditioning means, and the bypass air by the bypass air passage, Since the processing air is sent out to the air supply duct as processing air, the processing air is converted into dry warm air by mixing the heated outside air and the dehumidified air, and the dried warm air is used to further improve the efficiency of drying the stored products. Can do well.
[0020]
In addition, since the outside air is heated and mixed into the processing air, the inside air can be ventilated by introducing the outside air, and a function of improving the environment inside the room can be obtained.

The unloading container 5 is transferred to the processing shelf 2 by the transfer machine 6 and stored in the empty storage section 2a of the processing shelf 2 to automatically carry out the loading and unloading work. Repeatedly and alternately.
[0025]
Regarding the processing of the container-accommodated processed material W on the processing shelf 2, the adjusted air SA is blown out from a plurality of air outlets 7 a formed side by side in the shelf width direction toward a transfer machine path between the processing shelves 2, so that each processing is performed. An air supply duct 7 serving as an air supply duct for supplying the adjusted air SA to the front area of the processing shelves 2 (in this example, the transfer device moving space between the processing shelves 2) is provided in each processing shelf 2. The suction chamber 8 and the suction fan 9 are arranged below, and the suction chamber 8 and the suction fan 9 are configured to suction air from the storage section 2a of each processing shelf 2 through the suction chamber 8 provided on the rear side of the shelf. Each of the storage sections 2a in the shelf 2 is separately provided, whereby the suction air of the individual suction fan 9 causes the storage section 2a of each processing shelf 2 to suck the adjusted air SA from the front area of the shelf. Forced air SA By causing, for processing the stored treated in these housing portions 2a W (i.e. accommodation processing of storage container 5).
[0026]
On the back side of each processing shelf 2 in the processing cabinet 1, on the back side of each processing shelf 2, return air guide air that receives and merges the air RA sucked by the individual suction chamber 8 and the suction fan 9 from each storage section 2a of the corresponding processing shelf 2 A return air chamber 10 as a path and a machine room 13 which is disposed outside the air return chamber 10 and in which air flows in from the return air chamber 10 through the communication ports 11 and 12 are formed by partitions 14 and 15. Are provided with dehumidifiers 16 and 17 for dehumidifying the room air in the machine room 13 as air conditioning means.
[0027]
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 product W stored in each storage section 2a of the shelf 2 is dried in the above-described processing mode.
[0028]
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.
[0029]
In this processing system, the suction air RA by the individual suction chamber 8 and the suction fan 9 is guided to the machine room 13 in a merged state via the return air chamber 10 as a return air guide passage. The air guide path 13A for guiding the air RA from the return air chamber 10 to the dehumidifiers 16 and 17 as air conditioning means, and a part of the air RA from the return air chamber 10 to the dehumidifiers 16 and 17 The air that has been dehumidified by the dehumidifiers 16 and 17 is also used as a bypass air passage 13B to be bypassed, and is also used as a mixing chamber for the heated outside air OA supplied from the combustion type hot air blower 19 as the air heating means. A mixture of the bypass air from the bypass air passage 13B and the outside air OA heated by the combustion type hot air blower 19 is sent to the air supply duct 7 as the air supply air passage as the processing adjustment air SA.
[0030]
Two types of dehumidifiers are provided in the machine room 13; an integrated dehumidifier 16 that does not require an outdoor unit, and a separate dehumidifier 17 that requires a refrigerant pipe connection to an outdoor unit 17a disposed outside the refrigerator. The integrated dehumidifier 16 cools and dehumidifies the air taken into the machine from the periphery of the machine by a refrigerant evaporating coil, and subsequently reheats the cooled dehumidified air by a refrigerant condensing coil and sends it out of the machine. On the other hand, in the separate type dehumidifier 17, the air taken into the inside of the machine (indoor unit) from the periphery of the machine is cooled and dehumidified by the refrigerant evaporation coil, and subsequently, the cooled dehumidified air is reheated by the refrigerant condensing coil and sent out of the machine. In doing so, the amount of reheat can be adjusted by adjusting the amount of heat released outside the refrigerator by the refrigerant condensing coil of the outdoor unit 17a.
[0031]
As for the inflow of air from the return air chamber 10 to the machine room 13, the partition 14 between the return air chamber 10 and the machine room 13 has a lower communication port 11 formed near the floor and an upper portion formed near the ceiling. A communication port 12 is provided. The lower communication port 11 is provided with an auto-roll type dust filter 21 as air purifying means for purifying the passing air RA in the lower communication port 11. A communication port fan 22 that functions as an air circulation fan together with the suction fan 9 and the air supply fan 20 is provided in the unit 12.
[0032]
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.
[0033]
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.
[0034]
The container 5 accommodating the processing objects W in an accumulated state is provided with two surfaces, a front surface and a back surface (four surfaces including both lateral surfaces in some cases and a bottom surface in some cases) so as to allow the conditioned air SA to pass therethrough. 4), the processing air is sucked into the storage section 2a from the front surface area of the shelf, and the processing air is sucked into the storage section 2a. In order to prevent the flow to the storage section 2a, the storage sections 2a adjacent vertically and horizontally are separated by wind shield walls 25 and 26.
[0035]
Further, in order to prevent the suction-adjusted air SA from being sucked into the suction chamber 8 from the gap between the container rear surface and the rim of the suction chamber 8 while bypassing the storage container 5, As a sealing means for closing the gap in the storage portion 2a, the back portion of the container 5 is brought into contact with the storage of the container 5 so that the space between the back portion of the container and the edge of the suction chamber 8 is elastically airtight. An elastic packing 27 made of rubber or the like is attached to the edge of the suction chamber 8.
[0036]
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. When the curtain-like body 28 is closed and the curtain-like body 28 is closed, a ventilation hole 29 having a porous structure is formed to face the front surface of each container 5. The SA is sucked into each storage section 2a from the vent hole 29 so as to concentrate on the front surface of each storage container 5.
[0037]
In other words, while the high processing efficiency is ensured by the forced ventilation of the regulated air SA, the functions of the wind shield walls 25 and 26, the elastic packing 27, and the curtain member 28 with the ventilation port form the suction chamber 8 for each storage section 2a. In combination with the individual arrangement of the suction fan 9 and the prevention of diffusion of the used adjusted air RA in 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. It is.
[0038]
As shown in FIG. 6, with respect to the curtain 28, in the closed state, the horizontal core members 30 are attached to the main sheet member 28a (the sheet member having the ventilation holes 29) to be spread over the entire front surface of the shelf at appropriate vertical intervals. 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. 6 (b), the curtain-like body 28 is opened in a folded state where the core material becomes a fold, and 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 content 5 from / to each storage section 2a of the processing shelf 2 is performed.
[0039]
Further, the suction air RA by each suction chamber 8 and the 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 forming the partition 14 by the discharge air. It prevents flapping and suppresses the soaring of dust contained in the discharge wind.
[0040]
[Another embodiment]
Next, another embodiment will be described.
[0041]
The supply air guide path which blows out and supplies the adjusted air SA to the shelf front area in a state of being diffused may be a chamber structure instead of the duct structure (air supply duct 7) as in the above-described embodiment. Instead of being arranged at the lower part of the shelf 2, it may be arranged at the side or upper part of the corresponding shelf 2, the upper and lower middle part of the corresponding shelf 2, or the front facing portion of the corresponding shelf 2. Further, the number, shape, and structure of the outlet 7a for blowing out the adjusted air SA can be variously changed.
[0042]
The return air guide passage that guides the suction air RA from the suction fan 9 to the air conditioning means may be replaced with the partition chamber structure (return air chamber 10) as in the above-described embodiment, and may have a duct structure or a box chamber structure in some cases. .
[0044]
In the case where the return air chamber 10 and the machine room 13 are partitioned and formed in the refrigerator as in the above-described embodiment, the relative arrangement relationship between the return air chamber 10 and the machine room 13 formed on the back side of the shelf can be variously changed. For example, as shown in FIG. 7, the return air chamber 10 is formed on each of the back sides of the two processing shelves 2, whereas one machine chamber 13 is formed at one end of the processing shelves 2 in the shelf width direction. It may be formed so as to extend over both return air chambers 10.
[0045]
When air purifying means is provided at a communication port through which air flows from the return air chamber 10 into the machine chamber 13, the air purifying means is not limited to the dust filter 21, and various purifying methods such as an electric dust collector can be adopted. Instead of purifying only a part of the air RA flowing into the machine room 13 from the return air chamber 10 by the air purifying means, the entire amount of the air RA flowing into the machine chamber 13 may be purified by the air purifying means. .
[0046]
The individual suction chambers 8 and the suction fans 9 force the adjusted air SA from the front side of the container into the storage containers 5 (containers storing the processing objects W) in the respective storage sections 2a of the processing shelves 2. 5, the upper surface of the group of articles to be processed is covered with a cover-like wind shield made of a sheet material, a plate material, etc., so that the regulated air suction from the front of the container into the container can be more accurately performed. May be made more efficient.
[0047]
In addition, instead of causing the suction chamber 8 to function as an air suction for substantially the entire back surface of the storage container 5, suction is performed on a portion of the rear surface of the storage container 5 between the upper edge and a certain dimension downward. The chamber 8 is structured so as not to perform the suction function, so that even if the container 5 has a small storage capacity of the processing object W and an empty space is generated above the group of processing objects inside the container, adjustment is made via this empty space. The air SA may be prevented from being sucked into the suction chamber 8 in a short-circuit manner, so that efficient and uniform processing of the processing object W may be maintained.
[0048]
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. Heating or humidification, or a combination thereof may be used. The air-conditioning means for adjusting the suction air RA guided by the return air duct and the air-conditioner provided in the machine room 13 as the air-conditioning means are not limited to dehumidifiers, but may be air coolers, air heaters or humidifiers. What is necessary is just to select according to the processing content of the processing object W, such as a machine or a combination thereof.
[0049]
In addition, 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.
