Description

[Detailed description of the invention] The present invention relates to an improvement of a bran removal device in a circulating r^rice manner.

As for rice milling for home use in rural areas, since the rice milling structure in Japan is dualized between large concentrated rice milling factories in cities and small rice milling machines in depopulated rural areas, each household in rural areas is able to produce their own polished rice. The iJ3 has become a custom, and we need to rationalize it.

Traditionally, two types of rice milling methods have been used for this household use, one of which is that brown rice passes through the same milling chamber once (as shown in Figure 1). !11 This is a horizontal rice milling machine with a bran removal type, and the rice milling machine is almost sufficient to remove the bran, but the drawback is that when the milling part wears out, the rice cannot be milled in one pass.The other type is milled as shown in Figure 2. The chamber is part of the circulation process connected to the tank, and the milling process continues until the whiteness reaches the specified level by passing through the chamber several times.4) In the type 1 shield ring rice milling machine, the milling part is worn out. Even if the efficiency decreases, there is no limit to the milling time, so the process will continue until the desired level of white melon is obtained.
If you put it in place, there is a convenient ease in which you can finally achieve your goals. However, in this case, the rice grains flow continuously in a circular manner during the circulation process, and the structure of the milling room lacks the bran removal effect, so the sticky rice grains are mixed with rice grains. Dirty, filthy white rice that cannot be removed and has no shelf life is unavoidably used regularly. Although it is a small-scale and easy-to-handle operation, it is a simple circulation type, but the defect of insufficient bran removal is fatal.

Next, even with a vertical type circulating rice mill, the defects due to incomplete bran removal are larger than those with a horizontal type, and almost no effect on bran removal can be expected, so there are no examples of successful implementation.

Figure 3 is an example of (a), in which the rice grains being sent down the milling section are discharged in a flow-like manner around the circumference and flow down the sloped surface of the conical wire mesh in a slightly floating state (), so that the rice grains are (a) It is almost impossible to remove the sugar that has settled, and it is difficult to remove the M wire that falls under the screen to the outside of the tank. There is.

In the present invention, rice grain bundles are pressed against the porous wall surface by stirring pieces forming a milling trochanter in the milling section, and the rice grains separated from the surface of the rice grains are stirred by the centrifugal force caused by the revolving flow and the wind blown out by the trochanter. Due to the porous wall 1), the rice is ejected out of the tank and suctioned through the bran removal channel and discharged to the outside of the machine from the JJI bran mouth, so the rice can be thoroughly removed and finished by taking advantage of the vertical circulation rice milling machine that does not have a mackerel box. It is possible to mill the beautiful polished rice that has been milled, and the rice becomes even brighter when a strong wind is emitted from the blast hole of the milling trochanter, or when the rice bran is forcibly sucked out by connecting the rice bran removal channel to an exhaust fan. It was carried out in
Moreover, the main shaft of the vertical electric motor used in the transmission WJ device is used for removing rice bran.
It is an ideal vertical circulating rice mill that is simple and light, and is located on the axis of JI Building 11.

The present invention provides a small-sized vertical shaft WJI rice milling machine with sufficient bran removal action, and eliminates only 1! 17 for removing the bran if a @ machine is used.
By integrating the main shaft of 1 river 1 shaft and the main shaft of JIA (electronic rf that transmits the rice milling machine), it promotes the stirring friction action of the porous wall and the stirring piece which is the polishing trochanter, and the peeling action of adhering rice bran, which is essential for circulating rice milling JXI. The effectiveness of the new I7), which made it possible to mill and refine beautiful milled rice using the circulation milling machine, which was considered superior to conventional rice milling machines, was to fully demonstrate its bran removal effect.

In particular, when strong wind is sent into the hollow air passage of the vertical shaft by a blower and is blown into the milling trochanter along with the stirring action of the milling part r from the blast hole, the bran removal effect is further promoted (σ1 polishing effect Song Increased.

In the polishing trochanter of the present invention, if the rice grains are pushed against the porous wall (= I), which is effective for stirring friction, it is convenient to use a blade-shaped stirring body on the instep, and it is also convenient to use a blade-shaped stirring body on the instep. In order to facilitate the circulation of rice grains in the mortar-shaped container, a downward spiral trochanter is inserted in the upper part, and a lower spiral trochanter is inserted in the lower part to facilitate the circulation of rice grains in the mortar-shaped container.

Also, the 8 mortar-shaped holes for circulation! Several resistance protrusions are installed in the bran removing part (), and the resistance force of each protrusion adjusts the suppressing frictional force between the rice grains pushed out laterally from the milling part (9), thereby controlling the milling capacity. There is a device that can be increased or decreased.

Embodiments of the present invention will be described with reference to FIGS. 4 and 5. A perforated wall rice bran removing part 4 is provided in the low circumference of a circulating mortar-shaped container 3 containing a milling part 2 mounted on a vertical shaft 1. ), the outer periphery of which is covered by a mantle wall 5 to form a bran removal path 6, an IJI bran lower is opened in the main part of the bran removal path 6, and the electric motor connects the bran removal lower to the vertical shaft 1 by a belt 8. A vertical shaft circulating rice milling I is equipped with an N ton 10 mounted on the shaft end of the shaft 11 (11 is an air intake [112]), and the hollow part 1 of the vertical shaft 1 is equipped with a milling trochanter 2.

A lower downward spiral trochanter 19 is mounted on the upper part of the milling trochanter 2, and a downward spiral trochanter 20 of the F section is mounted on the F section of the milling section T-2.
A 3 IC is installed in the container 3, which acts as a propulsion force for smooth circulation of grains, and is an important trochanter for a vertical circulation rice mill that has a bran removal effect. Reference numeral 21 denotes a resistance protrusion located on the bran removing portion 4 of the porous wall of the container 3.
