Description

[Detailed description of the invention] This invention is an unpackaged brown rice storage system that can store a large amount of brown rice that has been harvested from each field, dried, and hulled for a long period of time without being affected by variations in its moisture content. It provides facilities.

First, an embodiment of the present invention will be described based on the drawings. Figure 1 shows the outline of the unpackaged brown rice storage facility.
Reference numeral 1 denotes an elevator that feeds unwrapped (bulk) brown rice sent from a hulling plant (not shown) into a rough sorter 2, and 3 a weighing machine that weighs the unwrapped brown rice discharged from the rough sorter 2. The unwrapped brown rice that has come out of the weighing machine 3 passes through a water content sorting process A newly established according to the present invention, and then is transported by an elevator 4 to a plurality of brown rice storage tanks 6A, 6B, 6C, and 6D installed in a cold room 5. ，
It will be carried into 6E, 6F, 6G, and 6H. Low temperature room 5
The temperature and humidity inside the tank are controlled by an air conditioner (not shown) to the optimum conditions for long-term storage of brown rice. It is made breathable so that natural circulation (or forced circulation) can occur.

7 stores unwrapped brown rice in any brown rice storage tank 6A
- Brown rice storage tank 6A so that it can be put into 6H
A carry-in conveyor is arranged above the 6H group so as to be rotatable around the starting end of the conveyance, and 8 is a brown rice storage tank 6A to 6H so that stored brown rice can be taken out from any brown rice storage tank 6A to 6H. An unloading conveyor is disposed at the bottom of the group so as to be rotatable around the conveyance end. 9 is an unloading conveyor 8
A relay conveyor that conveys the unwrapped brown rice from the conveyance terminal end to the sorting machine loading elevator 10 installed outside the cold room 5, 11 is the sorting machine, 12 is the weighing machine, 13 is the unwrapped brown rice after weighing, and is shipped. Place and loading conveyor 7
This is an elevator that can be selectively transported toward the return elevator 14.

The water content sorting process A is configured as follows. That is, as shown in Fig. 2, continuous moisture measurement is carried out in which unpackaged brown rice is sampled and its moisture content is measured during the transfer route of the unpackaged brown rice after passing through a coarse sorter 2 and a weighing machine 3 to an elevator 4. A device 15 and a moisture sorting device 16 for sorting unpackaged brown rice by moisture content based on the measurement results are provided, and only unpackaged brown rice whose moisture content is below a specified value is stored via the elevator 4. Carry into tanks 6A to 6H,
This device is configured to transport brown rice whose moisture content exceeds a specified value to a drying room (not shown).

The illustrated moisture sorting device 1 includes a mobile conveyor 17 that can freely move back and forth in the conveyance direction and change the conveyance direction by switching the rotation direction forward and backward, and selectively separates unwrapped brown rice by this mobile conveyor 17. A plurality of tanks 18A, 18B, 18 to be put into
C, and a discharge conveyor 19 which is disposed below these tanks 18A, 18B, and 18C and whose conveyance direction can be switched.

Further, the continuous moisture measuring device 15 samples the brown rice taken out from the weighing machine 3 and measures the moisture content, performs this measurement a predetermined number of times within the time set by the timer, and calculates the moisture content using the calculator 20. The system calculates the total moisture content and calculates the average value. Then, this average value is taken as the moisture content of the batch, and if the average value is less than the set value, the mobile conveyor 17 transports the unwrapped brown rice to the left in FIG. 2 and puts it into the tank 18A. When 18A is full, the entire mobile conveyor 17 is transferred to the second
Move to the right in the figure and put it into the tank 18B. When the average value exceeds the set value, the conveyance direction of the mobile conveyor 17 is switched, and unwrapped brown rice whose moisture content exceeds the specified value is put into the tank 18C.

The discharge conveyor 19 carries each tank 18A to 18.
When one of the shutters provided at the bottom of C is opened, it rotates in a predetermined direction, and the shutter and the mobile conveyor 1
7, a control circuit is installed to prevent unwrapped brown rice from being put into the tank which is being discharged by opening the shutter.

Since the present invention has the above configuration, even if there is variation in the moisture content of brown rice, brown rice with moisture content exceeding the specified value is automatically removed, and only brown rice with moisture content below the specified value is stored in the brown rice storage tank. This allows for long-term storage without loss of quality.

Furthermore, brown rice with a moisture content exceeding the specified value can be stored in the same way by passing it through a separate drying process and then returning it to the unwrapped brown rice transfer path of the proposed facility.
