Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a grain milling device for polishing brown rice in a grain milling section provided in a grain milling room.

(Prior art) A rice polishing machine equipped with a resistance adjustment device is placed under the hulling machine in a series process to enable dehulling and polishing. There is a known configuration in which a hopper is provided, which constitutes a grain feeding port that can feed grain directly to a rice milling machine, and can be used for three purposes: dehulling rice, dehulling, and rice polishing (Jikkosho).
37-27550).

(Problem to be solved by the invention) However, in the above-mentioned form, when the grain to be fed is paddy, a hopper for paddy is used, and when brown rice is fed, a dedicated hopper is used, so it is difficult to use the raw material. It is necessary to determine the type of grain and then switch to feed it to a predetermined hopper, requiring a separate switching means for each, or a relationship in which the hopper section is configured between the upper husking machine and the lower rice milling machine. This leads to an increase in bulk.

(Means for Solving the Problems) This invention attempts to eliminate the above-mentioned drawbacks and takes the following technical measures. That is, in the grain miller 1, there are provided a hulling section 2, a grain milling section 3, and a grain supply section 5 which is provided with a discrimination sensor 4 for discriminating between paddy and brown rice. When the grains are determined to be paddy, the grains are hulled between the pair of dehulling rolls 15 and 16 of the hulling section 2, and then transported to the grain milling section 3; when the grains are determined to be brown rice, the pair of dehulling rolls 15, 16, the gap is enlarged and the grains are conveyed to the grain milling section 3 without hulling.

(Function) The grains supplied to the grain supply section are detected by the discrimination sensor 4.
It is determined whether it is paddy or brown rice. In the case of paddy, the paddy is sent to the hulling section 2 and a pair of dehulling rolls 1
While passing through the grains 5 and 16, the grains are subjected to a hulling treatment, and then supplied to the grain milling section 3 where they are milled. on the other hand,
If it is determined to be brown rice, use the above-mentioned depu roll 1.
The interval between the grains 5 and 16 is widened, and the brown rice passes through the space, passes the hulling process, and is supplied to the grain milling section 3, where it undergoes the grain milling process.

(Effect) Regardless of whether the grains supplied are paddy or brown rice, the grain milling section 3 can perform grain milling mainly for brown rice with less paddy, so the grain milling section 3 is not clogged. Good grain milling work is possible. In addition, in the case of brown rice, the path is the same as in the case of paddy, but a pair of dehulling rolls 15, 1 in the hulling section 2 is used.
6 By widening the spacing, the hull processing is not performed, so there is no need to configure separate supply hoppers or supply routes, simplifying the configuration. By passing the brown rice through it, dust mixed in the brown rice can be removed and it is effective to prevent clogging of the bran removal screen.

(Example) Hereinafter, an example of this invention will be described in detail based on the drawings.

First, to explain its structure, the grain miller 6
is a box-shaped shed with a rectangular plan view and a horizontal partition wall 7 near the center in the longitudinal direction. A working room 8 and a machine room 9 are formed by the partition wall 7, and each room 8, 9 is provided with doors 10, 11 which can be accessed from outside. The machine room 9 includes a grain polishing cylinder 12 projecting through the partition wall 7 to the working chamber 8 side, a grain polishing trochanter 13 rotatably installed in the grain polishing cylinder 12, and a grain polishing trochanter 13 rotatably installed inside the grain polishing cylinder 12. A grain milling section 3 is provided which is equipped with a bran removal net 14 and the like provided on the outer periphery.

In addition, in the machine room 9, a hulling section is provided with a pair of dehulling rolls 15 and 16 rotatably installed in the upper part and a winnowing chamber 18 having a rotatably installed fan 17 in the lower part. 2 are provided. In addition,
The peeling roll 16 is provided with a roll gap that can be adjusted with a motor 23 with respect to the other rolls 15. That is, when the discrimination sensor 4 discriminates that the rice is paddy, the gap between the rolls is narrowed, and when the discrimination sensor 4 discriminates that the rice is brown rice, the gap between the rolls is opened so that the rice cannot be hulled. Further, a grain supply section 5 is provided close to the inner wall of the grain mill 1 on the side of the machine room 9, and a discrimination sensor 4 capable of discriminating between paddy and brown rice is provided on the bottom surface. The discrimination sensor 4 is an optical sensor that includes a light emitting element (e.g., a light emitting diode) and a light receiving element (e.g., a phototransistor). It is configured to make a determination. The lower end of the grain supply section 5 communicates with a grain lifting device 20 that communicates with a hopper 19 provided at the top of the hulling section 2.

Reference numeral 21 denotes the grain milling section 3 for the grain milling section 3 in which the grain rice is sent by a rice grain helix 32 installed at the bottom of the wind sorting chamber 18.
This is a rice thrower for hoisting grain into a grain hopper 22 provided at the top of the rice bowl.

There are two discharge ports 25 and 26 on the lower side of the grain polishing section 3.
In addition to providing a separate discharge funnel 24,
The motor 3 in relation to the discrimination result of the discrimination sensor 4
A switching valve 27 that can switch the discharge direction at zero is provided so as to be switchable and adjustable. Note that the motor 30
The driving of the motor 23 is instructed by a microcomputer (not shown). Below each of the discharge ports 25 and 26, a take-out device (in this embodiment, it is a spiral) 2 having a plurality of take-out ports is provided.
8 and 29 are provided.

31 is a collection funnel for collecting the finished rice discharged from the grain milling cylinder 12 to the working chamber 8 side, and 33 is a rice husk collection box.

Next, its effect will be explained. First, when grains are supplied to the grain supply section 5, the discrimination sensor 4 determines whether the grains are paddy or brown rice. If the grains are determined to be paddy, the grains are fried by the grain frying device 20 and supplied into the hopper 19, and then removed from the paddy by the shredding rolls 15 and 16 of the hulling section 2. After being rubbed, it falls into the wind selection room 18 and the fallen rice helix 32
will be collected. At this time, remove rice husks and foreign objects using fan 1.
7 and sent into the rice husk collection box 33, the fallen rice collected by the fallen rice helix 32 is sent to one side, and then fried by the thrower 21 and fed into the hopper 22. . The grains then fall into the grain polishing cylinder 12 of the grain milling section 3, where they undergo a milling process with the rotating grain milling rolls 13, and then are discharged into the collection funnel 31. On the other hand, the bran and some of the rice husks discharged from the rice bran removal net 14 to the outside of the grain milling barrel 12 enter the take-out device 29 through the discharge funnel 24 and the discharge port 26.
It is collected into a collection bag from each outlet.

Next, if it is determined that it is brown rice, the motor 2 receives a drive command signal from the microcomputer.
3 is driven to move the dehulling roll 16 to a place where hulling processing cannot be performed, and the motor 30, which similarly receives a drive command signal from the microcomputer, is driven to switch the switching valve 27. Therefore, the brown rice fed into the hopper 19 via the grain frying device 20 passes between the dehulling rolls 15 and 16 and falls into the wind selection chamber 18, where it is subjected to wind selection action and then removed. Collected by Rakumai Rasen 32. And Slowa 21
The grains are then fed into the hopper 22 and fall into the grain polishing tube 12, where they are subjected to grain milling treatment with grain milling rolls 13 and then collected with a collection funnel 31.

On the other hand, the bran discharged from the bran removal net 14 to the outside of the grain polishing barrel 12 enters the takeout device 28 from the discharge funnel 24 through the discharge port 25, and is collected into the collection bag from each discharge port.

In this way, the grains subjected to grain processing are mixed with rice husks and some rice husks due to paddy/brown rice, and bran with some rice husks mixed in.
It can be collected separately in bran. In addition, since the hulling process is not performed in the grain milling section 3, clogging of the bran removal net 14 can be prevented. Furthermore, since unhusked rice is not hulled, it is possible to prevent shell cracking and damage, and when the rice passes through the hulling section 2, dirt and dust can be sorted out in the wind selection chamber 18, so that the bran removal screen 14 can prevent clogging and improve grain milling performance.
