Description

Whole rice pearling mill

The present invention relates to an apparatus for culturing an embryo from a brown rice to a white rice so as not to cause a loss of rice eyes.

If brown rice is cooked with white rice, there is an advantage of removing rice bran which has a bad influence on the taste, but there is a problem that rice is also removed with low nutritional value.

The embryo removes rice bran in the process and leaves more than 80% of the rice husk, making it rice with good taste and high nutritional value.

Conventionally, a part of the produced embryo is made into 9 ~ 8 minutes and the quality is not uniform. In addition, most of the produced embryos are removed from the horny layer covering the rice husk, There is also a drawback that it is easy.

The apparatus disclosed in the following patent document 1 has a structure in which a metal mesh which rubs a rice grain is provided with a portion which is opposite to the traveling direction of the rice for each hole formed in an oblique slanting direction in the longitudinal direction , The embryo survival rate is 70%, and the embryo survival rate of the embryo is decreased by taking the structure that can relieve the impact generated when the grapple collides with the hole, It is said that a embryo having a retention ratio of 90% or more is obtained.

Further, the embroidery processing apparatus disclosed in Patent Document 2 has a structure in which brown rice is forcibly rotated while being forcedly rotated between a rotating body at the center of the inside thereof and a mesh network surrounding the rotating body, wherein the brown rice is rotated and driven, The cutting tool is cut by the embroidery between at least one auxiliary cutting member provided in the cutting tool.

The following patent document 3 discloses an apparatus for manufacturing an embroidery microbe using a method in which a surface of a brown rice is finely and smoothly polished using a primary grinding blade coated with diamond particles of fine size and a secondary grinding blade made of a tungsten brush, Is obtained.

In the conventional embryo screening apparatus described above, generally, brown rice is horizontally fed and fed in a horizontal direction, or is fed upward, and upward embryos are discharged upward. When the brown rice is examined, the space between the rotating body of the center and the surrounding metal net surrounds and moves horizontally or upward, thereby causing friction by rotation.

However, since the distance between the surface of the rotating body at the center and the mesh is wider than the diameter of the brown rice in the bread making apparatus, the brown rice is irregularly rotated between them.

On the other hand, the appearance of brown rice has a long axis forming an elongated ellipse and a short axis orthogonal to this long axis. Since the rice grain is attached to one end of the long axis, when the long axis rotates horizontally at the stage of turning, It is peeled off in contact with the surrounding netting or the chunks covering the surface of the chunks are scraped off so that the embryo can not be obtained.

Therefore, it is expected that if the long axis is rotated vertically when the brown rice passes between the center of the grinding stone and the net, by improving the structure of the rice gruel, the rice gruel will not come into contact with the grinding stone or the net.

It is also preferable to adopt a downward type rinse machine which feeds the brown rice upward and recovers the rice from the bottom.

Korean Patent No. 10-0599555, Figure 6A Korean Patent No. 10-0776625, Figure 13 Korean Patent Publication No. 10-2013-0104499, Fig. 3A

It is an object of the present invention to provide an embryo clarifying apparatus having a structure in which brown rice is fed vertically up and down in a vertical direction so as to obtain a chick embryo free of damage to rice hulls and preserved to a horny layer.

In order to realize the above-mentioned object, the present invention is characterized in that the present invention includes a conventional down-feed type nib forming part such as a hopper for supplying brown rice, a grinding stone for grinding brown rice, and a net surrounding the grinding stone, And a plurality of slits are arranged at the bottom of the hopper so as to coincide with the pattern of grooves formed on the upper surface of the abrasive stone so that the attitude of the brown rice to be fed is adjusted such that the long axis extends in the longitudinal direction And at least one stirring rod is disposed on the outer peripheral surface of the upper end of the grinding stone so as to allow the bottom of the hopper to be scanned while rotating to mix the brown rice which has not passed through the slit, So that the brown rice is smoothly supplied to the grooves.

Further, in the embryo grinding apparatus according to the present invention, a plurality of grooves formed on the upper surface of the grinding stone are arranged so as to be inclined at a predetermined circumferential angle with respect to the upper end of the center of the grinding stone so that the area occupied by the grooves on the upper surface of the grinding stone is maximized You may.

Further, in the above-described configuration, the depth of the groove is formed so as to become deeper from the upper surface to the outer circumference of the abrasive stone, and the groove depth at the outer peripheral edge is formed in the range of 0.6 to 0.8 in the average long axis length of the brown rice. So that the brown rice moving along the groove can not be released to the outside at the time of changing the direction at the outer peripheral edge of the abrasive stone.

Further, in the embryo determination apparatus according to the present invention, the diamond layer may be coated on the inner circumferential surface of the groove in the above-described configuration to improve the cutting efficiency.

In the present invention, only the brown rice fed to the hopper on the upper side takes a certain posture through the slit at the bottom, and is selectively guided into the upper groove of the grinding stone. When the guided rice moves along the groove and descends around the grinding stone Since the long axis is rotated and rubbed against the net, it does not come into contact with the grinding stone or its surrounding metal in the process of making the rice, so that the raw rice is preserved at the level of white rice. In addition, since the horny layer covering the rice husks is preserved without any damage, there is an advantage that the acidosis of the rice husks does not occur even after storage for a long time after the rolling.

In addition, since the grooves are arranged in an inclined manner at a predetermined circumferential angle with respect to the upper end of the center of the grinding stone, the area occupied by the grooves is increased, thereby improving the supply efficiency of the brown rice.

Further, by setting the depth of the groove at the peripheral edge of the grinding stone to be in the range of 0.6 to 0.8 in the average long axis length of the brown rice, the brown rice moving from the upper surface to the outer peripheral side of the grinding stone is not released to the outside .

In addition, the diamond layer coated on the inner circumferential surface of the groove improves the yield of the brown rice.

Hereinafter, the present invention will be described in detail as a preferred embodiment with reference to the accompanying drawings.

As shown in Fig. 1, the apparatus of the present invention comprises a hopper 2 for supplying brown rice as a basic constitution, a grinding stone 4 arranged at the center of the lower side of the hopper 2, A grinding wheel 6 surrounding the periphery of the grinding stone 4 and a motor 8 for rotating the grinding stone 4, and the like.

The brown rice not shown in the figure is introduced into the hopper 2 and rubbed against the net 6 while dropping along the periphery of the grinding stone 4 and collected through a collection port 10 provided at the lower side, In addition, the rice bran peeled off from the brown rice in the course of the ripening is discharged to the outside through the exhaust port 12 surrounding the outside of the metal net 6.

The grinding stone 4 is driven by the rotational force of the motor 8 through the belt 12, but the grinding stone 4 can be directly driven by the motor 8 In this case, since the size of the apparatus can be greatly reduced, it can be suitably used for the purpose of the household embryo shaping apparatus.

In the apparatus of the present invention, the grinding stone 4 has grooves 40 that are engraved in the longitudinal direction on the outer circumferential surface, and the upper end 42 of the center is disposed so as to protrude through the bottom of the hopper 2, On the outer peripheral surface of the upper end portion 42, at least one or more stirring rods 44 are provided.

2 is an enlarged view showing the bottom of the hopper 2 and the upper structure of the grinding stone 4. The stirring rod 44 extends from the upper end portion 42 to the upper surface of the hopper 2, The grooves 40 formed on the outer periphery of the grinding stone 4 are arranged in a radial shape extending around the upper end portion 42 of the grinding stone 4 and at the bottom of the hopper 2, 20 are formed in a large number of through holes.

3, the slit 20 is placed in the hopper 2 so that the long axis of the brown rice W is aligned with the longitudinal direction of the groove 40 Only the brown rice is selectively passed, and the brown rice passed is led to the upper surface groove 40 of the grinding stone 4.

The slits 20 are arranged so as to coincide with the radiation pattern formed by the grooves 40 around the upper end portion 42 of the grinding stone 4. [ In this embodiment, the radiation patterns of the slits 20 and the grooves 40 are arranged in a twisted direction at a certain circumferential angle with respect to the center upper end 42 so that the occupied area of the slits 20 and the grooves 40 is the maximum The amount of brown rice to be supplied to the grinding stone 4 at one time is maximized.

The stirring rod 44 placed above the slit 20 rotates together with the grinding stone 4 to sweep the bottom of the hopper 2. [ 4, the stirring rod 44 interferes with and interferes with the brown rice W during the rotation, thereby promoting the change in the attitude of the brown rice W which does not pass through the slit 20 and is horizontally stretched, The feeding efficiency of the brown rice W through the slits 20 is improved.

In the structure in which the grooves 40 are vertically arranged on the outer periphery as in the case of the grindstone 4 shown in this embodiment, the contact time of the brown rice W with the metal mesh 6 is minimized and the grinding efficiency can be lowered . In this case, if the angle of extension of the grooves 40 on the outer periphery of the grinding stone 4 is inclined at a predetermined angle in the circumferential direction with respect to the central axis 14, the brown rice W is descended along the outer periphery of the grinding stone 4 As a result, the time for coming into contact with the metal mesh 6 becomes longer, and the galling efficiency can be improved.

The grooves 40 may be formed in a pattern gradually deeper toward the outer circumferential direction of the grinding stone 4 around the upper end portion 42. The depth of the grooves 40 on the outer circumference of the grinding stone 4 may be, More preferably in a range of 0.6 to 0.8.

When the depth of the grooves 40 is limited by the above dimensions, both sides of the grooves 40 act as walls when the brown rice rides on the outer circumferential surface at the upper part of the grinding stone 4, Thereby preventing the brown rice W from bouncing to the outside.

 In the embryo screening apparatus of the present invention, the brown rice W falls down by its own weight when its long axis coincides with the slit 20 in a parallel manner, and the dropped brown rice W is fed to the grooves 4 of the grinding stone 4 And is moved toward the outer periphery by the action of the centrifugal force due to the rotation of the grinding stone 4 and is lowered while rubbing against the grinding wheel 6.

If the diamond layer is coated on the inner circumferential surface of the groove 40, the yield of the brown rice W can be increased.

When the upper and lower ends of the groove 40 are chamfered with an inclined surface, the inclined surface serves to guide the dropped brown rice W into the groove 40.

The brown rice W transferred into the groove 40 moves to the groove 40 formed on the outer peripheral surface of the grinding stone 4 and descends as shown in Figure 6A, ). This makes it possible to obtain a complete embryo without contacting the grain of the rice with the metal mesh 6.

Even if the brown rice W is lowered and rotated in the opposite direction to that shown in Fig. 6A, that is, as shown in Fig. 6B by 180 degrees, the rice grain portion still contacts with both side walls forming the grooves 6 and grooves 40 This results in a complete quality embryo.

As described above, in the embryo grinder of the present invention, the brown rice supplied to the grindstone is fed and grooved so that the long axis thereof is placed in the vertical direction in guiding the brown rice between the grindstone and the gauze to perform friction grinding The rice husk area of brown rice does not cause contact with the surrounding structures, but is made into a complete embryo.
