The container k is taken in and out by the container transport device 22 provided for the above.

  The racks 21a to 21d of the present embodiment are provided with partition plates S every two rows, and form rack chambers D1 to D4, respectively. Between the racks 21a to 21d provided in each of the rack chambers D1 to D4, container transfer devices 22a to 22d for putting the container k in and out of the rack 21 are provided. The container transfer devices 22a to 22d are configured to be movable by stacking containers k in the horizontal direction and the vertical direction between the opposing racks 21 and placing or removing the containers k on the rack 21.

The rack chambers D1 to D4 are respectively provided with air conditioners 23a to 23d for controlling the temperature and humidity in the rack chamber, and one rack chamber D4 is provided with a dehumidifying device 24.
The dehumidifying device 24 in the rack chamber D4 includes a suction fan 24a and a suction pipe 24b, and the suction pipe 24b is connected to each container k placed at the lowest stage of the rack 21d through a switching valve 24c as shown in FIG. It is configured.

  The conveyance start end sides of the container conveyance devices 22a to 22d are configured to be connected to a container transfer conveyor 25 for transferring the container k between the container conveyance devices 22a to 22d. The container transfer conveyor 25 changes the direction of the container k and relays it to the container transfer devices 22a to 22d, and transfers the container k from the container relay portion 25a to another rack transfer devices 22a to 22d. Part 25b. Reference numeral 26 denotes a loading / unloading conveyor for loading and unloading the container k. 27 is a cover member that covers the container transfer conveyor 25 and the loading / unloading conveyor 26, and 28 is a blower fan that returns the room temperature to normal temperature by blowing normal temperature into the cover member 27 and taking it out of the rack chamber D. It is.

  The air conditioning control in the rack chambers D1 to D4 will be described. The rack chambers D1 to D4 adjust the air conditioners 23a to 23d so that the brown rice is stored at a temperature (for example, 15 ° C.) and humidity (50 to 60%) for a long period of time. is doing.

  The grain storage facility of the present embodiment is a facility that mainly prepares and stores the brown rice brought by the producer, but temporarily stores the dried rice cake until it becomes semi-dry (for example, about 18%) moisture. A case will be described in which the present equipment is used when it is stored or finish-dried to finish moisture (for example, 14.5%).

  After drying to moisture in a semi-dry state (for example, about 18%) from another drying facility (not shown), the soot stored in the low temperature storage chamber (not shown) is transferred and stored in the container k. Then, the container transport device 22d is placed at the drying rack position r1 at the bottom of the rack 21d in the rack chamber D4. When the suction fan 24a of the dehumidifying device 24 is driven to open the switching valve 24c, the suction pipe 24b communicates with the suction pipe connecting portion (not shown) of the container k containing the semi-drying cake, so that it is semi-dry. The straw is sucked and dried to finish moisture.

With this configuration, the rack 21 can be used not only as a storage rack for storing brown rice, but also as a drying rack that dries to a finish moisture that can be crushed with semi-dried rice cake before the brewing process.
Further, the dehumidifying device 24 does not need to be provided in all the rack chambers D. Further, by adopting a configuration that can be used for a part of the containers k in the rack chamber D, a compact dehumidifier can be used, and finishing with inexpensive equipment is possible. A drying process can be performed.

  In addition, the rice bran having a low grain temperature cannot immediately perform the hulling operation, and the rice taken out from the low-temperature storage chamber (not shown) takes time to reach room temperature. Since the grain temperature can be returned to room temperature while finishing and drying, the semi-dry rice cake taken out from a low-temperature storage chamber (not shown) can be made into a rice cake that can be crushed in a short time.

  The dehumidifying device 24 according to the present embodiment is configured to be able to communicate with the container k placed at the lowermost stage of the rack 21d. However, the dehumidifying apparatus 24 may be configured to communicate with the uppermost container of the rack 21d or other specific container. good.

Next, a process of gradually drying the semi-dry rice cake to the finished moisture over several days using the equipment of the present embodiment will be described.
The container k containing the semi-dry cake is transported to the rack chamber D4 and placed at the drying rack position r1 where the container transport device 22d performs dehumidification drying with the dehumidifying device 24. Then, the suction pipe 24b and the container k are set to communicate with each other, and the switching valve 24c is opened.

  The dehumidifying device 24 is activated, and the dehumidifying and drying operation is performed until the suction air from the suction fan 24a acts on the semi-drying cake in the container k and becomes near the finished moisture (for example, 15.2%). The detection of whether or not it is near the finishing moisture is performed by removing the container k from the rack 21d by the rack transport device 22d and transporting it by the container transfer conveyor 25 at a set time, and inverting the container k by the reversing device 30. Is put into the temporary hopper 31, is weighed by the temporary weighing machine 32, is again put into the container k, and is transported to the base drying rack position r1.

  Moisture is measured with the moisture meter 33 during the period from when the container k is inverted and the soot is discharged to when the soot is put into the container k again. When the measured moisture reaches near the set finishing moisture (for example, 15.2%), the container k is transported from the drying rack position r1 to the storage rack position r2 by the container transport device 22d.

  At this time, the value of the weigh scale is detected at the time of high moisture at the initial stage of dehumidification drying, and the moisture value of the semi-dry rice cake is determined based on the difference from the previous measurement value. It is good also as a structure. When the measured moisture reaches the set moisture, the container k is transported from the drying rack position r1 to the storage rack position r2 or the rack 21 of another rack chamber D by the container transport device 22d.

  In other words, it is difficult to calculate the moisture with a moisture meter because of the large variation of moisture at high moisture, so it is detected by weight, and when the finished moisture is low, the variation of moisture becomes small, so the measurement accuracy with the moisture meter increases. It is used.

  When the dehumidifying and drying operation is finished, the container k is transported to the storage rack position r2 by the container transport device 22d and placed on the storage rack position r2, and is naturally finished by the air conditioning control of the air conditioner 23d (for example, 14.5%) is gradually air-dried.

  A container k containing the next semi-dry cake is placed on the empty drying rack position r1 and dehumidified and dried. The semi-drying cake in the container k can be prevented from being over-dried by first dehumidifying and drying the semi-drying cake and then naturally ventilating and reducing the variation in moisture during finishing. it can. Further, when the finishing moisture is reached, the grain temperature can be brought to a state close to room temperature, and the hulling operation can be performed immediately when necessary.

  Alternatively, the container k of the bag that has reached the finish moisture may be moved to the rack chamber D that is adjusted to another storage temperature and humidity for storage. That is, in this case, the rack chamber D4 adjusts the air conditioner 23d to a temperature and humidity that can be dried (for example, about 60% humidity at 20 ° C to 25 ° C), and the air conditioners in the rack chambers D1 to D3 to store the grains. Adjust the temperature and humidity (about 70% humidity at 15 ° C).

Next, a method for entering and leaving the container k in the rack 21 will be described.
In the grain storage facility according to the present embodiment, data of stored grains (variety / rank / moisture) for each container at the time of warehousing is input. It is set as the structure which leaves. Usually, a slightly larger amount (for example, 1080 kg) than the displayed weight (for example, 1000 kg) is accommodated in the container k to prevent moisture from being reduced to an amount smaller than the displayed weight. By giving priority to the advanced items, it is possible to prevent troubles that are smaller than the displayed amount at the time of delivery.

  In this embodiment, the dehumidifying device 24 is provided as a device for drying the soot, but it may be a heating device.
