Description

[Detailed Description of the Invention] The present invention is to mill brown rice and remove minute amounts of shoulder lines etc. attached to the surface of the milled white rice to easily obtain glossy polished rice with high whiteness. This relates to a one-time rice polishing machine that can be used for one pass.

That is, this invention corresponds to the rice polishing outlet of the milling chamber,
Its gist is the structure of a single-pass rice polishing machine, which is characterized by having a rice bran removal case with a large number of small holes drilled on its circumference, and a rotatable impeller installed inside the case. be.

The present invention will be explained with reference to an illustrated embodiment. Reference numeral 1 denotes a brown rice hopper for storing brown rice, and is provided at the upper part of a box.

The bottom of the brown rice hopper 1 is formed in the shape of a funnel, and a milling chamber 2 is connected to the opening at the tip so as to allow free circulation.

The milling chamber 2 is of a conventionally used and known type, and is provided with a cylindrical bran removal screen, the tip of which is open as a milled rice discharge port 3.

Further, a resistive lid 4 is press-fitted to the polished rice discharge port 3 so as to be able to swing freely.

A pumping roll 5 is rotatably inserted into the pumping chamber 2.

The central axis 6 of the pumping roll 5 is extended long in the front and back.
The rear end is interlocked with an electric motor via a pulley and a belt, and the tip penetrates the center of the resistance lid 4 and projects forward.

Reference numeral 7 designates a rice bran removing case having a large number of small holes 8 for removing rice bran on its circumferential surface, and is provided corresponding to the rice polishing outlet 3.

Reference numeral 9 denotes an impeller, which is provided at the tip of the central shaft 6 so as to freely rotate within the bran removing case 7.

That is, the impeller 9 is provided by the boss 10 at the tip of the central shaft 6 so as to be slidable in the front-rear direction but fixed in the rotational direction.

In addition, two parts of the circumferential surface of the bran removal case 7 are cut out and a spout opening 11 is formed.
If this is done, the polished rice put into the case 7 will be thrown out of the case 7 by the impeller 90 revolutions.

An adjustment knob 12 is provided on the outer surface of the bran removal case 7.

This knob 12 is rotatably screwed into the case 7 so as to move back and forth by rotating left and right, and its tip abuts against the boss 10 of the impeller 9.

Further, a spring 13 is provided between the boss 10 and the resistance lid 4.

Through this boss 10 and spring 13, the adjustment knob 12
This makes it possible to easily adjust the degree of pressure of the resistance lid 4 against the rice polishing outlet 3.

In this embodiment, the impeller 9 is configured to rotate around the central shaft 6, but it may be rotated by other means regardless of the central shaft 6.

Further, 14 is a polished rice container, and 15 is a rice bran box.

Since this invention is configured as described above, brown rice is put into the brown rice hopper 1, and the central shaft 6 is used to roll rice into the milled rice roll 5.
When the impeller 9 is rotated, the brown rice is milled in the milling chamber 2 to become polished rice, and the polished rice is passed through the resistance lid 4 of the milled rice outlet 3.
is pushed outward and discharged into the bran removal case 7.

The discharged white rice is removed from the rice bran removal case 7 by rotating the impeller 90 times.
The shoulder lines on the surface of the polished rice are removed from the bran by rubbing against the inner surface of the case I, and the removed shoulder lines are passed through the small holes 8, 8 on the circumference of the case 7 for removing the bran. As a result, polished rice with high whiteness and gloss can be obtained.

Furthermore, if the bran removal case 9 is provided with a spout 11, the polished rice will be discharged to the outside of the case 9 and stored in the polished rice container 14.

As described above, according to the present invention, the polishing of brown rice and the removal of the shoulder line of the polished white rice are performed consistently, and it has the practical benefit of easily obtaining glossy white rice with high white discoloration. It is.
