Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention is a grain milling machine for producing white rice from brown rice, for example,
This relates to a bran-removal barrel that surrounds the milling trochanter and forms a milling chamber.

(b) Conventional technology As mentioned above, in a grain milling machine, the configuration of the bran removal cylinder which also surrounds the milling trochanter and forms a milling chamber is known as a conventional technique, for example, as disclosed in Japanese Utility Model Publication No. 40-3101. The ones shown in are known.

That is, the bran removal holes formed on the circumference of the rice bran removal tube shown in this publication are cut out in the shape of a cedar arbor to promote the movement and reversal of the grains in the chishima spermatozoa to improve agitation. Therefore, it is intended to uniformly separate the grains into four grains.

However, with this rice bran polishing cylinder, the friction between the grains in the island spermatozoa was not sufficient and it became difficult to polish the rice in a short period of time.

(c) Problems to be solved by the invention As described above, with the conventional bran removal miller, it is possible to give uniform Ushijima action to the grains, and evenly milling can be achieved, but the friction between the grains Therefore, it was difficult to obtain milled grains in a short time because the action was not sufficient, so the present invention aims to increase the friction between the grains in the milling chamber, and at the same time, to This invention was created with the aim of obtaining refined grains in a short time by also aiming at the movement and reversal of the grains. In order to achieve the purpose described in (c), a protrusion that protrudes into the chamfering chamber is provided on the inner circumferential surface of the bran-refining barrel that surrounds the four-island spermatozoa and forms the chamfering chamber. By appropriately arranging them, they constitute a bran removal cylinder in a grain milling machine.

(E) Function With this configuration, the number of grains supplied into the sperm extraction chamber is 4
Due to the frictional effect caused by the rotation of the sperm trochanter, the grains are moved and reversed in the milling chamber, and are then separated into four islets. The grains collide with the protrusions arranged on the inner circumferential surface of the grain milling cylinder and irregularly invade the inside of the milling chamber, increasing the degree of friction between the grains and, due to this penetration, causing damage to other grains. The grains inside the seminal chamber are forced to move and turn over, and are subjected to the action of four islets.

The bran produced by this milling action is sequentially discharged from around the bran removal barrel, and the bran is separated to obtain refined grains.

(f) Example Hereinafter, the present invention will be explained in detail based on embodiment figures.

The grain milling machine shown in this example diagram is a small vertical friction type rice milling machine.
As shown in Fig. 11, the key point of its construction is that a clay part cylinder (2) and an inverted R-shaped lower cylinder (3) are placed upright inside a frame (1), and the upper part A brown rice tank (4) is mounted, supported by a cylindrical body (2) and a frame body (1). (4), the grain feeding chamber (6) and the bird sperm chamber (7) are continuously formed vertically, and the grain feeding chamber (7) is connected to the grain feeding chamber (7).
), followed by the Rice Research Room (8).

There is a rice bran discharge chamber (9) between the polishing chamber (7) and the lower cylinder (3), and a rice bran passageway 00 between the rice polishing chamber (8) and the lower cylinder (3). are formed respectively, and this bran passage 0
0 is a rice bran discharge fan (lit) at the bottom of the lower cylinder (3).
A fan with a built-in fan communicates between the chamber aZ and the rice bran discharge chamber (9).

α is the vertical rotation axis that connects the above-mentioned grain feeding chamber (6) and milling chamber (7).
The storage area of the grain feeding room (6) has a spiral round shape, and the storage area of the pounding room (7) has a grain storage area that can be rotated freely. Wings αS are formed to form a milling trochanter (a), and a rice polishing member aS is attached to the storage part of the rice polishing room (8).

(17) is from the lower part of the frame (1) to the lower cylinder (3)
A drive shaft is protruded inward and rotatably installed, and a cylindrical body σS is fitted and fixed to the upper part of the drive shaft α, and the bran discharge fan σD is attached to the lower part of the cylindrical body. The lower end of the rotating shaft αl is fitted and fixed to the upper part.

Further, a polished rice outlet tpi is opened on the negative side of the rice polishing chamber (8), and this polished rice outlet [+! J is equipped with a pressure regulating valve Q11 that is automatically energized by the bullet ■0. In the figure, the symbol indicates the supply or stop of brown rice from the brown rice tank (4) to the grain feeding room (6). shutter, G is white rice exit [
This is the gutter where white rice overflows from +9.

The above is an outline of the configuration, and the brown rice that is sequentially supplied from the brown rice tank (4) through the supply port (5) into the grain feeding chamber (6) when the shutter ■ is opened is integrated with the drive shaft [171]. The grain is transferred downward in the grain feeding chamber (6) by the grain feeding helix U4 of the rotating shaft a3 that rotates, and enters the one-island sperm chamber (7).
Here, the four-island spermatozoon (a) undergoes a four-island sperm effect due to the friction caused by stirring and the mutual frictional action of the brown rice. The rice bran produced by these four islands is separated from the white rice and placed in the rice bran discharge chamber (9).
The discharged white rice flows into the rice polishing chamber (8), is polished by the rice polishing member stop, and is overflowed from the white rice outlet σ9 by pushing open the pressure regulating valves Q and D, and is received in a predetermined container from the outlet gutter.

Further, the bran discharged from the above-mentioned bran discharge chamber (c+j VC) flows into the fan chamber (13K) from the bran passage 01 and is discharged by the bran discharge fan σV.

Next, to explain the main part of the present invention, the above-mentioned milling chamber (7) is formed by a bran removal cylinder (b) that surrounds the milling trochanter (a) forming the milling wing tya. However, as shown in Figures 1 and 2, and Figures 5 and 6, this bran removal barrel (b) has a left half part (
b) and the right half (b2) are joined and integrated into a cylindrical shape, and the inner circumferential surfaces thereof are marked with the markings shown in Figs. 3 and 4, and Figs. 7 and 8. As shown in the developed view, the hemispherical protrusions (c) shown in Fig. 10 are placed at appropriate intervals both vertically and horizontally.
are made to protrude into the extraction chamber (7), and between the vertical rows of these protrusions (c) and on both sides, there are cedar-shaped bran removal holes (d). In arranging the above protrusion (Cl), for example, the lower ends of the adjacent bran removal holes (dl) and (d2) and the wire removal holes (d2) and (d3
) is also located between the upper end of each of the positions σ.

In addition, cl! 4) and mother are the flange parts that were formed into a semi-cylindrical shape on the left half (bl) and then welded to the upper and lower edges, and ■ and punishment are the flange parts that were similarly welded to the right half part (b2). It is.

Therefore, in the Hitsujijima spermatic chamber (7), the spermatozoa (a)
The brown rice, which is subjected to the four-island fertilization effect due to the rotation of , collides with the protrusion (c) and irregularly enters the inner side of the milling chamber (7), increasing the degree of friction between the brown rice and other brown rice. It will also force you to move and flip.

In addition, with the rotation of the four-island spermatozoa (a), the spermatozoa (7)
The brown rice moving inside has a cedar-shaped hole for removing bran (d)
For example, the brown rice that has moved as shown by the arrow in Figure 4 changes its direction by the protrusion (C) and moves as shown by the arrow (B), repeating reversals during that time. While doing so, it begins to receive the effects of ejaculation.

(G) Effects of the Invention As described in detail above, the present invention includes a method in which a protrusion that projects into the milling chamber is appropriately arranged on the inner peripheral surface of the bran-refining barrel that returns the milling trochanter to form the milling chamber. Since the grains are moved within the spermatozoa due to the rotation of the four-island trochanter, they collide with the protrusions and enter the irregular Vc4J and into the spermatozoa. This increases the degree of friction between the grains, and this invasion forces other grains to move and turn over, so the four-island fertilization is further promoted and refined grains can be obtained in a short time. Furthermore, it has the feature of moving and inverting the grains, making it possible to mill evenly and uniformly.
