Abstract

PURPOSE:To make it possible to blend unhulled rice according to the needs of a customer and, at the same time, improve the feasibility of laying out a unhulled rice storage hopper and other relating devices. CONSTITUTION:A common transport pipe 10 is arranged on a rice hulling device 3 in a control chamber 2 consisting of a rice hulling device 3, a rice polishing device 4 and a stone extraction device 12 so that the unhulled rice is fed from external unhulled rice storage hoppers 1a to 1d and the received unhulled rice is transported. The feed of the unhulled rice from the storage hopper is controlled by a designation signal such as blended grade and quantity from a control part 8. Thus, the process to hull the blended unhulled rice, extract stone and polish the rice is performed continuously.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hulled rice polishing apparatus and is used by being installed in a rice grain store or a large-scale retail store.

[0002]

2. Description of the Related Art A form is known in which a plurality of types of brown rice are blended to be refined.
However, regarding the form of blending the paddy, there is a form of treating the same grade and taste in addition to the same type, but the blended paddy is not supplied according to the customer's request.

[0003]

In view of the above, the present invention has been made in view of the above.
At the paddy stage, rice blending was carried out according to the customer's request, and the following technical measures were taken. That is, at least the hulling device 3 and the rice polishing device 4 are arranged in the machine room 2, and a common transfer pipe 10 for feeding the hulls from the plurality of hull storage hoppers 1a to 1d and transferring the hulls to the hulling device 3. In the above, a structure of a hulled rice polishing apparatus in which each discharge port of the plurality of paddy storage hoppers is seen.

The transfer pipe 10 is made of a flexible material.

[0005]

The function and effect of the present invention Since the paddy blending can be carried out according to the customer's request and the rice polishing process can be performed as it is, the customer can confirm the paddy state and set the blending ratio and the like. In addition, inside the machine room 2 and a plurality of storage hoppers 1a ...
1d is connected by a transfer pipe 10 to convey air,
Since this is made of a flexible material, the layout of the storage hopper with respect to the machine room 2 can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The rice hulling and rice polishing device includes a plurality of storage hoppers 1a to 1d, a rice hulling device 3 and a rice polishing device 4 installed in the machine room 2, a rice hull cyclone 6 and a bran cyclone 7, which are provided in the dust treatment chamber 5.
And a control unit 8 and the like.

The above-mentioned storage hoppers 1a to 1d are provided so as to be able to store paddy for different types of products, and a feeding valve 9a is provided below each of them.
9d are provided and communicated with the supply hopper 11 of the hulling device 3 via the flexible transfer pipe 10. The hulling device 3 employs a known impeller type. A stone removing machine 12 is arranged below the hulling device 3, and the debrowned brown rice is configured to pass through the stone removing machine 12 and then collected in a transport hopper 13. The rice polishing device is adjacent via a transfer pipe 14. It is configured so that it can be supplied to four.

The air transfer fans 15 and 16 to be transferred in the transfer pipes 10 and 14 are installed in the lower space of the rice polishing apparatus 4. The rice polishing apparatus 4 has a configuration in which a vertical polishing roller (not shown) is arranged on the vertical axis to process the brown rice supplied into the polishing chamber from the upper side and discharge it from the lower side. A switching chute 17 is connected to the discharging portion, and is switched between an unpolished rice reducing path for returning to the transport hopper 13 and an extracting path for regularly taking out the polished rice. Reference numeral 18 is a weighing hopper provided at the polished rice outlet, and 19 is a weighing machine. The weighing hopper 18 is connected to the white rice outlet 20 and can be taken out of the machine.

The rice husk cyclone 6 and the bran cyclone 7 are connected to the rice hulling device 3 and the rice polishing device 4, respectively, and are air-transferred by the suction fans 21 and 22 through the transfer pipes 23 and 24. 25 is a rice husk collection bag, 26 is a bran collection bag. Two
Reference numerals 7 and 27 are filters. Operation CRT2 for control unit 8
8 is provided, and various selection items displayed on the screen can be operated by a direct touch operation on the screen. That is, it is possible to select the paddy in the storage hoppers 1a to 1d and the amount thereof (which can be set depending on the number of rotations of the feeding valve), and to calculate the charge statement corresponding to it and output it to the printer.

A door 29 having a transparent glass 28 fitted therein is provided in the machine room 2 for accommodating the hulling device 3, the stone removing device 11 or the rice polishing device 4. On the other hand, the dust processing chamber 5 is also provided with a similar door 30. The operation of the above example will be described. Raw material rice is put in advance in the storage hoppers 1a and 1b for each different type. The customer inputs the required product type on the screen. When blending multiple types, enter the type and weight. The feeding valve of the corresponding product is rotated to feed a predetermined amount of paddy, and the paddy is sent to the paddy huller 3 through the transfer pipe 10. When the amount of paddy to be blended is different, blended paddy with a predetermined ratio is obtained by changing the feeding valve rotation time or the valve rotation speed.

When the paddy hulling device 3 is activated and the paddy is supplied from the feed hopper 11 into the device, the paddy that flows down sequentially from the feed hopper 11 is removed. The unpolished brown rice flows down to the stone removing machine 12. Here, it is possible to separate and take out unimportant foreign matters such as stones mixed with brown rice supplied to the surface of the sorting board in the specific gravity sorting mode. The brown rice is collected in the transport hopper 13 and sent to the rice polishing apparatus 4 by air transport. Since the first small amount cannot be completely polished in the polishing chamber, the switching chute 17 is switched to the side of the unpolished rice reducing passage until the predetermined time elapses after the operation is started, and the one in the polishing chamber is once returned to the transport hopper 13. After the lapse of the predetermined time, the switching chute 17 is switched to the regular takeout route side, and the white rice hopper 20
Collect it in a white rice bag that is prepared as appropriate.

The rice husk discharged from the rice hulling device 3 and the rice husk discharged from the rice polishing device 4 are captured by cyclones 6 and 7, respectively, and collected in the rice husk collecting bag 25 and the rice bran collecting bag 26. Regarding the installation configuration of the machine room 2, the dust treatment chamber 5, the control unit 8, and the storage hoppers 1a to 1d, the storage hoppers 1a to 1
d and the machine room 2 have a connecting portion of the transfer pipe 10,
Since the transfer pipe 10 is configured to be flexible, the position with respect to the machine room 2 is not limited and the layout property can be expanded.
The same applies to the relationship between the machine room 2 and the dust processing room 5. The same effect can be obtained by forming the transport pipes 23 and 24 with a flexible material.
