Description

  The present invention relates to a drying warehouse provided with a drying device for drying a processed product at a drying temperature, and a storage warehouse provided with a storage device for storing the dried processed product at a storage temperature lower than the drying temperature. And a dry storage facility.

  As a conventional technique related to such a dry storage facility, a drying facility provided with a drying warehouse for drying a harvested product such as potato or onion harvested in a field is described in Patent Document 1, and fresh food, chemical products, etc. Patent Document 2 discloses a refrigeration facility provided with a refrigerated warehouse for refrigerated storage at a low temperature. In order to improve the capacity of such facilities, in general, the processing capacity is improved by increasing the scale of the facilities, such as increasing the size or the number of warehouses.

Japanese Patent No. 3555673 JP 2004-299800 A

By the way, the dry warehouse of patent document 1 and the refrigerated warehouse of patent document 2 are warehouses which perform independent processing with respect to the processed material, respectively. For example, when refrigerated storage of harvested potatoes and onions, In order to maintain, the excess moisture is once dried before refrigerated storage and then refrigerated for storage, so two different warehouses, a drying warehouse and a refrigerated warehouse, are required.
As described above, if a dry storage facility having both a drying function and a refrigerated storage function is configured using a conventional drying warehouse or refrigerated warehouse, a warehouse is provided for each function. Will become larger. In particular, when trying to construct a dry storage facility with high drying processing capacity and refrigerated storage capacity, the problem of increasing the size of the equipment is prominent because each of the drying warehouses and refrigerated warehouses will be dealt with by increasing the size and number of them. It becomes.
In particular, when harvesting harvested by natural cultivation, such as potatoes and onions, is the target of processing, a large amount of harvest is concentrated during the harvesting period. The quality of the harvest cannot be maintained. Therefore, a dry storage facility with a high drying processing capacity is preferable so that many harvested products can be dried at a time in preparation for the harvest time.
On the other hand, in order to continuously and stably supply harvests such as potatoes and onions other than the harvest time to the market, it is necessary to preserve as many harvests as possible. Therefore, from the viewpoint of stable supply of processed products, a large-scale dry storage facility with high storage capacity is preferable.
As described above, when a high drying capacity required for harvesting time and a high storage capacity required for stable supply are realized by using a conventional drying warehouse or refrigerated warehouse, the drying storage equipment becomes larger.

  Therefore, a dry storage facility that can increase both the drying processing capacity and the storage capacity of the harvested product while avoiding an increase in the size of the equipment is desired.

The characteristic configuration of the dry storage facility according to the present invention includes a drying warehouse equipped with a drying device for drying a processed product at a drying temperature, and storing the dried processed product at a storage temperature lower than the drying temperature. A dry storage facility having a storage warehouse with a storage device to perform,
At least a part of the drying warehouse is a dry storage combined warehouse equipped with the storage device, and the dry storage combined warehouse stores a processed product by a drying operation for drying the processed product by the drying device and the storage device. The point is that it can be switched to a storage operation.

According to this characteristic configuration, the amount of water adhering to or contained in the processed product is dried to an amount suitable for storage by drying the processed product in a drying warehouse at a drying temperature, and then processed in the storage warehouse. The product can be stored at a storage temperature lower than the drying temperature. Thereby, a processed material can be preserve | saved in a favorable preservation | save state.
And if there are many processed items to be dried in the drying warehouse, the drying processing capacity of the equipment will be increased if the drying storage warehouse is operated for drying, so that the generated processed products are dried with a relatively high capacity. be able to. On the other hand, if there is little occurrence of processed material to be dried in the dry warehouse, the storage capacity of the equipment will be increased if the dry storage combined warehouse is operated, so even if there are many processed products that have been dried so far, Those processed products can be appropriately stored.
For this reason, when there is a peak demand for drying treatment, such as drying processing for potatoes, etc., which concentrates on the harvesting season, the dry storage warehouse is operated for drying at the peak demand for the drying treatment. When the peak time has passed, the dry storage combined warehouse is stored and operated, so that the drying warehouse capacity required at the peak time of the drying process request and the storage request after the peak time of the drying process request have passed. Compared to a dry storage facility that simply has a dry warehouse and a storage warehouse according to these capacities, while having both of the capabilities of a storage warehouse, both functions can be performed even in the same storage space. The size of the equipment can be suppressed by the amount that it bears.
Thus, it is possible to increase both the drying processing capacity and the storage capacity of the harvested product while avoiding an increase in the size of the equipment.

  Here, the processed product is a crop harvested from a field, and further includes a long-term storage warehouse including a long-term storage device for storing at a long-term storage temperature lower than the storage temperature. The storage warehouse stores the harvested product cooled from the drying temperature to the storage temperature at the storage warehouse at the long-term storage temperature, and at least a part of the long-term storage warehouse includes the storage device. It is preferable that the dual-purpose storage warehouse is configured to be switchable between a storage operation for storing the processed material by the storage device and a long-term storage operation for storing the processed material for a long time by the long-term storage device. It is.

According to this configuration, since the processed product is a harvested product such as potato or onion harvested from the field, when the product is stored for a long period of time, it is stored in a state where deterioration of the quality of the product does not proceed as much as possible. Is preferred. When storing fresh products for a long period of time, ice temperature storage (storage near 0 degrees Celsius) is generally performed, but in the case of harvested products, the drying process is performed before storage, so the harvested products become relatively hot, If the ice temperature is suddenly preserved from that state, a sudden temperature change occurs, resulting in damage to the harvest, and there is a problem in terms of quality maintenance. In that respect, according to the above configuration, the harvested product after the drying treatment is once cooled in the storage warehouse from the drying temperature to the storage temperature before being stored in the long-term storage warehouse, and then stored in the long-term storage warehouse. Saved. Therefore, since the temperature change generated in the dried crop can be moderated, damage to the harvest can be reduced. In this way, high quality preservation of the harvest is possible.
Moreover, since a part of the long-term storage warehouse can be used as a storage warehouse that is necessary for alleviating the temperature change of the harvest as described above, the amount of harvest stored is relatively low, such as at the beginning of the harvest period. Since it is possible to effectively use a long-term storage warehouse that is not used when there are few, it is possible to suppress the number of storage warehouses installed and avoid an increase in the size of the equipment.
Therefore, it is possible to preserve the harvested product with high quality while avoiding the enlargement of the equipment.

  In addition, when storing the processed product by the storage device, the storage warehouse separates the processed product dried by the drying warehouse from the processed product before being dried by the drying warehouse. It is preferable to store in the area.

  For example, when the processed product waiting for drying processing and the processed product after drying are stored in the same storage warehouse, if water vapor generated from the processed product before drying diffuses into the storage area of the processed product after drying, the precious drying process is performed. This may reduce the quality of the processed product after drying. In this regard, according to this configuration, by forming different storage areas that are partitioned by providing a partition body or the like, diffusion of water vapor between these two storage areas is prevented, and the two storage areas Even if there is a difference in humidity, it is possible to prevent the humidity from being balanced between the two storage areas. In other words, when the processed product before drying and the processed product after drying are stored in the same storage warehouse, the processed product after drying should not be affected as much as possible by the water vapor generated from the processed product before drying. it can. Therefore, it is possible to maintain the quality of the processed product while avoiding the enlargement of the storage warehouse.

  A further characteristic configuration of the dry storage facility according to the present invention includes a transport device that performs a loading / unloading process on a storage shelf in which each of the dry warehouse, the storage warehouse, and the long-term storage warehouse stores a processed product. It is constituted by an automatic warehouse, and is characterized in that there is provided a communication conveying device that can convey a processed material between the conveying devices for each of the drying warehouse, the storage warehouse, and the long-term storage warehouse. .

  According to this feature configuration, the loading / unloading work is performed by the transfer device in each of the dry warehouse, the storage warehouse, and the long-term storage warehouse, and the processed material that is loaded / unloaded in each warehouse is transferred by the communication transfer device. Therefore, when performing a series of processes such as drying, storage, and long-term storage of the processed material, the load of the work transfer operation by the operator is reduced, and the dry storage facility is easy to use.

  The long-term storage temperature is preferably set in a range of −0.5 degrees Celsius to 0.5 degrees Celsius, and the storage temperature is preferably set in a range of 5 degrees Celsius to 15 degrees Celsius.

  According to this characteristic configuration, the harvest can be stored for a long period of time in an ice temperature storage state where deterioration of the quality of the harvest does not proceed as much as possible. Moreover, since the dried crop is acclimatized at a storage temperature set in the range of 5 to 15 degrees Celsius, it is possible to prevent a sudden temperature change from occurring in the dried crop. The damage done can be reduced. Therefore, the quality of the processed product can be appropriately maintained.

Outline of Equipment The dry storage equipment 100 of this embodiment is a drying warehouse A for drying a processed product by a dry air conditioner 11 (equivalent to the “drying apparatus” of the present invention), a low temperature air conditioner 12 (“storage apparatus” of the present invention). A storage warehouse B for storing the processed material at a low temperature, and a long-term storage warehouse C for storing the processed material at an ice temperature by the ice temperature air conditioner 13 (corresponding to the “long-term storage device” of the present invention). When a harvested product (for example, potato) harvested in the field is carried in as a processed product, the dry storage facility 100 has a temperature for drying until the moisture content in the drying warehouse A is suitable for storing the processed product. After drying for a predetermined drying time (for example, about 30 hours) in an air-conditioning environment at 30 ° C., a predetermined pre-cooling time (for example, for example) in an air-conditioning environment at about 10 ° C., which is a storage temperature, until the storage warehouse B adapts to a low temperature. Refrigerated for about 24 hours), and then stored in the long-term storage warehouse C in an air-conditioned environment at about 0 ° C., which is a temperature for long-term storage that is lower than the temperature for storage.

It has. Note that an air conditioner having both functions of the low temperature air conditioner 12 and the ice temperature air conditioner 13 may be used.

In the third warehouse 3, either the low temperature air conditioner 12 or the ice temperature air conditioner 13 is selectively activated when the operator performs a setting command operation on a command operation unit (not shown). When the storage operation command is instructed and the low-temperature air conditioner 12 is activated, the storage operation for storing the processed material is performed at the storage temperature, the long-term storage operation command is instructed, and the ice temperature air conditioner 13 is activated. A long-term storage operation for storing the processed material at a temperature for long-term storage lower than the temperature is executed.
In the present embodiment, the storage temperature in the third warehouse 3 is set in the range of 5 degrees to 15 degrees Celsius, and preferably 10 degrees Celsius, similar to the storage temperatures in the first warehouse 1 and the second warehouse 2. Set to The long-term storage temperature in the third warehouse 3 is set in a range of −0.5 degrees Celsius to 0.5 degrees Celsius, and preferably set to 0 degrees Celsius.

  As described above, the third warehouse 3 is a combined storage warehouse including the low-temperature air conditioner 12 and the ice temperature air-conditioner 13, and stores the processed object by the low-temperature air conditioner 12 that stores the processed object at the storage temperature. It is configured to be switchable between a storage operation and a long-term storage operation for storing the processed product by the ice temperature air conditioner 13 that stores the processed product at a long-term storage temperature lower than the storage temperature.

  The third warehouse space SS3 of the third warehouse 3 is partitioned by a partition 15 provided at an intermediate position in the warehouse longitudinal direction of the storage shelf 3a, and two different storage areas are adjacent to each other. The partition 15 includes a partition panel 15a that closes from the floor to the ceiling at each of the partition points of the pair of shelves constituting the storage shelf 3a, and a partition door 15b that closes the conveyance passage from the floor to the ceiling at the partition.

When the third warehouse 3 is stored and operated, the two storage areas formed in the third warehouse space SS3 are selectively used so as to store the processed products in different processing stages. That is, of the two storage areas formed in the third warehouse space SS3, the area close to the unloading space ST2 is such that the processed material carried into the dry storage facility 100 exceeds the drying processing capacity in the drying warehouse A. When a processed product waiting for the drying process is generated, it is a storage area before drying in which the processed product before the drying process is stored. On the other hand, the region far from the cargo handling space ST2 is a storage region before and after drying in which the processed material after drying processing in the drying warehouse A is stored.

  As described above, the third warehouse 3 which is a combined storage warehouse, when storing the processed product by the low temperature air conditioner 12, the processed product dried by the drying warehouse A and the harvest before being dried by the drying warehouse A. Store objects in different storage areas. By the way, in the present embodiment, the processed product stored in the third warehouse 3 is automatically distributed and stored into two storage areas by the transfer device 3b based on the processing progress information of the processed product. Of course, the worker may specify a storage area to which the processing object to be received corresponds.

  When the third warehouse 3 is stored and operated, the third warehouse space SS3 stores the processed product waiting for the drying process and the processed product after drying. In this case, the generated product is generated from the processed product before drying. If the water vapor to be diffused in the storage area of the processed product after drying, the effect of the pre-drying processing may be reduced, leading to deterioration of the quality of the processed product after drying. Therefore, by providing the partition 15, the diffusion of water vapor is prevented between the two storage areas of the pre-drying storage area and the pre-drying storage area, and even if there is a humidity difference between the two storage areas, The humidity is not balanced between the two storage areas.

  In addition, since the generation | occurrence | production degree of the processed material waiting for a drying process changes with the generation amount of the processed material in the drying process cycle in a harvest time, and the storage capacity of the drying warehouse A, the installation position of the partition 15 in the warehouse longitudinal direction is It is preferable to determine based on the amount of processed material generated in the drying process cycle at the harvest time and the storage capacity of the drying warehouse A.

  The fourth warehouse 4 includes an ice temperature air conditioner 13. Although detailed illustration is omitted, in the ice temperature air conditioner 13, a plurality of indoor units (not shown) provided on the ceiling of the fourth warehouse space SS4 and a refrigerant are circulated and connected to each of the plurality of indoor units. And a plurality of refrigerant supply pipes. In the fourth warehouse 4, the ice temperature air conditioner 13 is activated when the operator performs a setting command operation on a command operation unit (not shown). When a long-term storage operation command is instructed and the ice temperature air conditioner 13 is activated, a long-term storage operation for storing the processed material at a long-term storage temperature lower than the storage temperature is executed.

  Thus, the 4th warehouse 4 is equipped with the ice temperature air conditioner 13, and is comprised so that long-term storage operation which preserve | saves a processed material at the temperature for long-term storage lower than the temperature for storage may be performed. In the present embodiment, the long-term storage temperature in the fourth warehouse 4 is set in the range of −0.5 degrees Celsius to 0.5 degrees Celsius, similarly to the long-term storage temperature in the third warehouse 3, preferably , Set to 0 degrees Celsius.

5. Facility operation The dry storage facility 100 switches the operation mode of the second warehouse, which is a dry storage warehouse, and the third warehouse, which is a dual storage warehouse, depending on the time, and changes the quantity of the processing object to be dried and stores it at ice temperature. Corresponds to the quantity fluctuation of the target processed product.

  First, the operation of the dry preservation facility 100 in the harvest time (for example, from June to July) of the harvest that is the processed product will be described. During the harvesting period, it is necessary to sequentially dry the crops that are successively brought from the producer to the processed product dry storage facility 100. Therefore, as shown in FIG. 6, the harvesting period is such that both the first warehouse 1 and the second warehouse 2 of the dry storage combined warehouse are operated in the dry mode, and as shown in FIG. 2, the first warehouse 1 and the second warehouse 2 are operated. Both warehouses 2 and 2 are designated as dry warehouse A. The harvested product after the drying process in the first warehouse 1 and the second warehouse 2 is temporarily stored at the storage temperature in the third warehouse 3 in order to adjust to the low temperature. Therefore, the third warehouse 3 is operated in the storage mode as shown in FIG.

  In the present embodiment, when the third warehouse 3 is operated in the storage mode, the harvested product before drying and the harvested product after drying are sorted and stored in each of the two storage areas separated by the partition 15. For this reason, the pair of partition doors 15b in the partition 15 is normally closed. This prevents the movement of water vapor between both storage areas. In addition, when the stacker crane which is the transport device 3b travels to the storage area on the far side of the warehouse (the far side from the cargo handling space Z2) for loading and unloading the processed material after drying, the pair of partition doors 15b is in an open state ( It automatically switches to (see FIG. 3), and the stacker crane is allowed to travel at the partition.

  Next, the operation of the dry preservation facility 100 in the period after harvesting of the processed potato (for example, from August to March) will be described. In the post-harvest period, the processed product is not brought into the processed product dry storage facility 100 from the producer. Therefore, the dried product may be processed by drying the processed product to be shipped as described later. The drying processing capacity of the storage facility 100 can be reduced. Therefore, at the time after harvesting, as shown in FIG. 7, only the first warehouse 1 among the dry storage warehouses is operated in the dry mode, and the second warehouse 2 is operated in the storage operation mode. As a result, as shown in FIG. 3, the first warehouse 1 becomes the dry warehouse A, and the second warehouse becomes the storage warehouse B. Among the periods after harvesting, immediately after the harvesting period, the stock of processed products harvested at the harvesting time is the largest, so the capacity of the long-term storage warehouse C is increased as much as possible to preserve these processed products on ice. . Accordingly, the third warehouse 3 is operated in the long-term storage mode as shown in FIG.

  In the present embodiment, when the third warehouse 3 is operated in the long-term storage mode, the pair of partition doors 15b in the partition 15 are always open as shown in FIG. Similarly to the case, the closed state may be normally set, and when the stacker crane of the transfer device 3b needs to pass, it may be automatically switched to the open state temporarily.

  Hereinafter, the processing content of the processed material in the harvest time and the time after harvest will be described with reference to FIGS. 4 and 5.

  As described above, as shown in FIG. 4, the harvesting time is such that the first warehouse 1 and the second warehouse 2 are drying and both are drying warehouses A, and the third warehouse 3 is storing and operating. The fourth warehouse 4 is operated for long-term storage and becomes a long-term storage warehouse C. The arrows S1 to S3 in FIG. 4 indicate the movement of the harvested products, and are specifically processed by the transport cart 9 and the transport devices 1b to 4b in each warehouse.

  When the harvest is carried in, if the drying warehouse A can accept the harvest to be dried, the harvest is received in the drying warehouse A (arrows S1 and S1m) and the drying process is performed. If the available capacity of the dry warehouse A has decreased due to the drying process of the preceding harvest that has already been received in the dry warehouse A, and if some or all of the harvest that has been carried in this time cannot be accepted, accept it Unacceptable crops are temporarily stored in the storage area before storage in storage warehouse B (arrows S1 and S1s) and stored at low temperature until there is an empty space in drying warehouse A. The goods are taken out from the previous storage area and are put into the dry warehouse A (arrows S1 and S1m). Thereby, it can prevent as much as possible that quality deteriorates during the period of waiting for a drying process.

  When the drying process in the drying warehouse A is completed, the cargo is discharged from the drying warehouse A and is stored in the storage area after drying in the storage warehouse B (arrow S2). After storing in the storage warehouse B only for the pre-cooling period, the storage warehouse B gets used to the storage temperature, and then leaves the storage warehouse B and enters the long-term storage warehouse C (arrow S3). Although the shipment is carried out even at the harvest time, the harvested product from the long-term storage warehouse C may be shipped, but the harvested product from the dry warehouse A is used as it is or in the storage warehouse B. The harvested product may be taken out from the storage area after drying and used as a harvested product for shipping.

  As described above, the shipping time is as follows. As shown in FIG. 5, the first warehouse 1 is dried and operated as a dry warehouse A, the second warehouse 2 is stored and operated as a stored warehouse B, and the third warehouse. Both the third and fourth warehouses 4 are operated for long-term storage and become long-term storage warehouse C. Then, the amount of the harvest according to the shipping request is delivered from the long-term storage warehouse C, and the harvest that has been cooled to 0 ° C by storage at ice temperature is stored in the drying warehouse A rather than suddenly warming to the drying temperature. Enter warehouse B (arrow R1) and adjust to storage temperature. If it preserve | saves only for the pre-cooling period for shipping in the preservation | save warehouse B, it will take out from the preservation | save warehouse B, and will enter into the dry warehouse A in order to remove condensation (arrow R2). When the drying period for shipping has elapsed after entering the drying warehouse A, the harvested goods are delivered from the drying warehouse A (arrow R3) and shipped.
