Description

Milling device

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rice flour mill for removing rice hulls and processing rice.

Generally, rice flour is a device for removing rice hulls and processing them into rice. In recent years, small appliances have been developed which are capable of adjusting or selecting a portion of a grain such as brown rice or white rice according to consumer's preferences in a general household. The 'grain' of the grains represents the degree of ripening from the brown rice to the white rice state.

Conventional small planters feed rice into the cage and remove the rice hull by the rotating shaft in the cage, and at the same time, grind the surface of the rice husked rice and process it into rice suitable for the rice. The rice flour and rice bran produced in the process are separated by a suction duct, and rice is collected in a collection box.

The shaft according to the related art has an example in which a pair of protrusions extending in the longitudinal direction are coupled to a circular cross-section of a rod. However, in the case of the above-mentioned example, the balls may crack or break due to the impact of the projections on the balls. Further, when the protrusions are separately manufactured and bonded to the barrel, the manufacturing process can be troublesome.

On the other hand, conventionally, the cage is generally formed in a shape having a circular cross section hollow. In this case, since the inner circumferential surface of the cage is formed of a circular curved surface, the rice between the cage and the shaft during the rotation operation of the shaft has a relatively large degree of sliding along the inner circumferential surface of the cage. As a result, the yielding efficiency may be lowered. In addition, since the interval between the inner circumferential surface of the cage and the outer circumferential surface of the shaft is constant, mixing efficiency of the rice between the cage and the shaft can be deteriorated during the rotation operation of the shaft.

Fig.

1 to 5, the stirrer 100 includes a hopper 110, a transfer tube 120, a cage 130, and a shaft 140. The hopper 110 feeds the stationary object to the feed port 121 of the feed pipe 120. Here, the object to be roasted may be cereal having a shell, such as rice (1).

The conveyance pipe 120 provides a passage through which the rice 1 supplied through the hopper 110 is conveyed to the cage 130. The transfer pipe 120 may have a shape having a supply port 121 at an upper portion thereof and both ends thereof opened. The passage of the transfer pipe 120 may have a circular cross section or may have the same shape as the hollow of the cage 130.

The cage 130 includes the cage body portion 131 and the passages 132. The cage body 131 is made of a polyhedron having a hollow polygonal cross section. For example, the cage body portion 131 may be a hexagonal column having a hexagonal cross-section hollow. The hollow of the hexagonal cross section can be extended to a certain size along the longitudinal direction of the cage main body 131. The thickness of the cage body portion 131 between the inner wall and the outer wall may be constant. Of course, the cage body portion 131 may have various shapes in the category having a hollow having a polygonal cross-section such as a hollow having a rectangular cross-section.

When the cage body portion 131 has a hollow having a polygonal cross section, the inner peripheral surface of the cage body portion 131 is formed into a polygonal shape. Therefore, the rice 1 between the cage body portion 131 and the shaft 140 during the rotation operation of the shaft 140 has a low degree of sliding along the inner peripheral surface of the cage body portion 131, have. Since the distance between the inner circumferential surface of the cage body portion 131 and the shaft 140 varies during the rotation operation of the shaft 140, the mixing efficiency of the rice 1 between the cage body portion 130 and the shaft 140 Can be increased. Even if the pressing portion 141 of the shaft 140 has a circular cross section.

Both end portions of the cage body portion 131 are opened. One end of the cage body 131 is connected to the conveyance pipe 120 to receive the rice 1 from the conveyance pipe 120. The opposite end of the cage body 131 mainly discharges the rice in the transfer pipe 120. The opposite end of the cage body 131 can be opened or closed by the shutter 150 of the controller.

The through-holes 132 are formed in a plurality of through holes on each side of the cage body 131. The cylinder pockets (132) discharge the rice husks or rice bran peeled off from the rice (1) in the cage body portion (131) during the rolling process. The through-holes 132 are inclined at the same angle with respect to the longitudinal direction of the cage body 131 on the respective surfaces of the cage body 131, respectively. For example, the through holes 132 may be inclined at an angle of an arbitrary value in a range of 20 DEG to 25 DEG with respect to the longitudinal direction of the cage body portion 131. [

The through-hole 132 can be inclined toward the inclined direction of the screw groove 143a of the conveying screw portion 143, which will be described later. Therefore, when the rice 1 is moved by the feeding screw portion 143 while rotating in a spiral manner in the cage body portion 131, the rice husks or rice bran peeled off from the rice 1 in the cage body portion 131 132). &Lt; / RTI >

The through-hole 132 can be extended with a constant width. The cylinder block 132 may be rounded at both ends. The through holes 132 may be arranged at regular intervals along the longitudinal direction of the cage main body 131 in two or more rows. The through holes 132 are illustrated as being arranged side by side, but they may be alternately arranged.

The shaft 140 is inserted into the cage 130, that is, the cage body portion 131, and presses the rice (1) in the cage body portion 131 to contact the inner wall of the cage body portion 131 (141). The pressing portion 141 is formed such that the three pressing surfaces 142 are arranged along the circumferential direction and are connected and the connecting portions 141a of the pressing surfaces 142 are chamfered or rounded. Each of the pressing surfaces 142 has a concave groove 142a formed continuously from one end to the opposite end along the longitudinal direction at a central portion along the width direction.

Each of the pressing surfaces 142 may have a constant width and a predetermined length. In addition, the pressing surfaces 142 may be of the same size and shape. The concave groove 142a may have a predetermined curvature along the width direction of the pressing surface 142 and may be formed continuously along the longitudinal direction. Of course, the concave groove 142a may be formed in various shapes in the U-shaped category.

In addition, the concave groove 142a may be formed to be connected to the chamfered portion 142b by a predetermined interval in the longitudinal direction from the chamfered or rounded portion 141a. Therefore, the concave groove 142a can be smoothly connected by the chamfered or rounded portion 141a and the intermediate portion 142b. The width of the intermediate portion 142b may be chamfered or set narrower than the width of the rounded portion 141a. The intermediate portion 142b may be convexly curved or may be formed in a plane.

The aforementioned pressing portion 141 pivots the rice 1 transferred to the cage 130, that is, the cage body portion 131, while rotating it to the inner wall of the cage body portion 131 by rotating operation. In this process, the rice (1) rubs against the inner wall of the cage body portion (131) or rubs against each other, and thereby the rice husk of the rice (1) is peeled off and the surface of the rice husked grain is ground, It can be processed into rice.

At this time, during one rotation of the pressing portion 141, the rice 1 is moved toward the inner wall of the cage body portion 131 three times by the three pressing surfaces 142, so that the cutting efficiency can be increased . Since each pressing surface 142 is in contact with the rice 1 in the cage body portion 131 by the concave groove 142a, the pressure of the rice to be moved toward the inner wall of the cage body portion 131 1 can be increased to increase the cutting efficiency and the effect of mixing the rice 1 in the cage body portion 131 can be enhanced. In addition, since the inner circumferential surface of the cage body portion 131 is formed in the shape of a polygonal surface, it is possible to further improve the shaping and mixing efficiency as described above.

Further, since the pressing surfaces 142 are chamfered or rounded, the contact portions 141a are smoothly contacted with the rice balls 1, thereby preventing cracks or breakage of the grains. In addition, the pressing portion 141 can be chamfered or rounded at the leading end circumferential portion 141b inserted most deeply into the cage body portion 131, thereby preventing damage to the grains during rolling. The shaft 140 can be simply manufactured without requiring that the projections are formed by welding or the like, unlike the conventional shaft.

Meanwhile, the shaft 140 may further include a conveying screw portion 143 for conveying the rice 1 into the cage 130 in a rotating operation. The conveying screw portion 143 has a structure in which a screw groove 143a is formed with respect to a central axis along the longitudinal direction. The conveying screw portion 143 may be connected to the rear end of the pressing portion 141 and disposed in the conveying pipe 120. The rice 1 supplied into the feed pipe 120 is fed into the screw groove 143a of the feed screw part 143 while the feed screw part 143 rotates in the spiral direction of the screw groove 143a And then can be transferred into the cage 130 along the thread groove 143a by the rotation of the feed screw section 143. [

The conveying screw portion 143 may be integrally formed with the pressing portion 141 or may be processed separately from the pressing portion 141 and coupled to the pressing portion 141. [ The shaft 140 may have a rotation shaft 144 connected to the rotation driving mechanism at the rear end of the feed screw 143. The rotation shaft portion 144 receives the rotational force from the rotation drive mechanism and allows the shaft 140 to rotate.

Alternatively, as shown in FIG. 6, the concave groove 142a 'may be formed continuously from one end to the opposite end along the longitudinal direction of the pressing surface 142' in a V-shape.

7 and 8, the pressing portion 241 of the shaft 240 according to another example has three pressing surfaces 242 arranged and connected along the circumferential direction, (241a) may be chamfered or rounded, but may have a twisted shape with respect to a central axis along the longitudinal direction. The pressing surfaces 242 may have a constant width and a predetermined length before being twisted. Also, the pressing surfaces 242 may be of the same size and shape. The pressing portion 241 may be twisted at a tip of about 120 degrees with respect to the rear end, with respect to the feeding direction of the rice 1.

The pressing portion 241 according to the present embodiment is configured such that the rice 1 is pressed three times by the three pressing surfaces 242 for one rotation in the same manner as the pressing portion 141 according to the above- 131), so that the drawing efficiency can be increased. When the pressing portion 241 rotates in the twist direction, the rice 1 in the cage body portion 131 can be evenly processed while being evenly mixed by the twisted pressing surfaces 242. In addition, since the inner circumferential surface of the cage body portion 131 is formed in the shape of a polygonal surface, it is possible to further improve the shaping and mixing efficiency as described above.

Since the pressing surfaces 242 are chamfered or rounded, the portions 241a connected to the pressing surfaces 242 are smoothly contacted with the rice balls 1, so that cracks or breakage of the grain can be prevented. In addition, the pressing portion 241 can be chamfered or rounded at the tip peripheral portion 241b as in the pressing portion 141 of the above-described example, thereby preventing damage to the grain during rolling.

Each of the pressing surfaces 242 has curved surfaces 242a and 242b concavely curved on both sides in the longitudinal direction and curved surfaces 242a and 242b having both side portions concave with respect to the center portion along the longitudinal direction It can be twisted in a finished state. Here, each of the pressing surfaces 242 has a structure in which a central portion 242c between the curved surfaces 242a and 242b is protruded. The central portion of the pressing portion 241 can be rounded. The curved surfaces 242a and 242b of the pressing surface 242 may be bent in a curved shape with a certain curvature in both lateral directions before being twisted. Of course, the curved surfaces 242a and 242b of the pressing surface 242 may be formed in various shapes in a U-shaped form before they are twisted. The pressing surfaces 242 may be of the same size and shape.

As described above, the pressing portion 241 is formed with two curved surfaces 242a and 242b on the respective pressing surfaces 242 with respect to the center portion along the longitudinal direction, and the curved surfaces 242a and 242b A protrusion 242c protrudes from the protrusion 242c. As a result, the area of contact of the pressing surfaces 242 with the rice 1 in the cage body portion 131 is increased by the two curved surfaces 242a and 242b, It is possible to increase the amount of the rice 1 that is moved to the side of the rice paddy 1, thereby improving the yielding efficiency. Also, the effect of mixing the rice (1) in the cage body portion (131) can be enhanced. Although not shown, each of the pressing surfaces 242 may be formed as a flat surface or a curved surface before being twisted.

The twist direction of the pressing portion 241 may be set to be the same as the spiral direction of the screw groove 143a of the feed screw portion 143. [ When the screw groove 143a is in the clockwise direction, the twist direction of the pressing portion 241 can be set to the clockwise direction. When the spiral direction of the thread groove 143a is counterclockwise, the twist direction of the pressing portion 241 can be set to the counterclockwise direction. The rice 1 transferred to the pressing portion 241 along the thread groove 143a of the feed screw portion 143 during the rotation operation of the shaft 240 is rotated in the same direction by the twisted pressing surfaces 242 Lt; / RTI >
