DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

First, a process of removing foreign matter mixed or attached to the raw material is performed. This is done in a grain eliminator 10 that automatically removes various foreign substances contained in a raw material (denoting various kinds of grain such as wheat, rye, corn, barley, etc.) as shown in FIG. Thus, the foreign object removing device 10 removes foreign matter (straw, heavy grab, etc.) mixed or attached to the grain. The raw material is introduced into the grain eliminator 10 through the bucket conveyor.

The grains dirt remover (10) is provided with an enclosure capable of vibrating through a spring on the frame, and an air blower is installed in the enclosure for introducing wind pressure together with a turning view rotated by a driving motor. A hollow swash plate in concave form to select soil, sand and stone mixed in the grains, a swinging device for oscillating the swash plate, a control device for adjusting the inclination angle of the swash plate, a support for reducing the impact of the swash plate, And a blower blowing the air.

Therefore, in the grain remover 10, the raw material is injected into the circulation tower, and then sequentially exits the circulation network and passes through the screen network in a stepwise manner. At this time, a light foreign substance is discharged to the cyclone 1 through the blower 7 due to the wind pressure, and the grains mixed with the stones at the middle portion of the hoop plate having a certain shape of the groove are laid down shallowly on the inclined plate, The stone having a larger specific gravity and smaller size moves to the lower side of the grain layer due to the vibration of the steel plate and enters into the recessed surface groove and the grain is larger than the groove of the recessed surface to not completely enter into the groove, The grains slightly float because of the buoyancy due to the air current. In this state, when the vibration is continued by the swinging device, the grains slide down to the lower end of the swash plate, and the large friction stones rise to the upper end of the uneven surface and are separated.

The removal process of the grain foreign material is followed by the washing process.

The washing process is performed in the washing machine 12 as shown in FIG. The washing machine (12) floats the grains with the rotating impeller at the lower end of the hopper, discharges floating matters and debris, separates heavy materials (stones) heavier than grains from the lower part secondarily using the difference in specific gravity, So that the washed grain is passed through the rotary dehydrating drum and the rinse water is sprayed to remove the residual material and simultaneously dehydrate.

Following the washing process, the specific gravity separation process is performed.

The specific gravity separation process is performed by the specific gravity separator 14. The specific gravity separator 14 causes grains to flow on the slope screen and blow air under the slope to slightly float the grains while flowing, so that the foreign matter is sorted by the specific gravity difference. At this time, the swash plate moves forward and backward by swinging motion. When the specific gravity separation process is performed as described above, not only the remaining foreign substances adhered to the grain (raw material), but also the impurities mixed together are removed.

Following the specific gravity separation process, the degassing process is performed.

The removing process is carried out by the removing device 16 as shown in FIG. The degasifier 16 is a device for obtaining grains of grains by peeling the husks of grains. The degasifier 16 may be composed of a hopper having a grain inlet at the top, a rotor rotationally driven below the outlet side of the hopper, and a frictional cylinder surrounding the rotor. Therefore, in the hopper 16, the grains are fed through the hopper into the friction cylindrical body and the rotor, and friction occurs in the grain skin due to the rotation of the rotor, so that the grain can be quickly removed.

As shown in Fig. 1, there is a step of sequentially pulverizing the grain grains, which are peeled off after the peeling step, into at least four first to fourth grinders (21, 22, 23, 24).

At this time, the first to fourth crushers 21, 22, 23, 24 include a pair of crushing rollers 21a, 21b each having the same diameter. It is preferable that the crushing rollers 21a and 21b have teeth T1 and T2 gradually becoming smaller in accordance with the order of the first to fourth crushers 21 and 22, Do.

For example, as shown in FIG. 2, when a pair of crushing rollers 21a and 21b are shown, teeth T1 and T2 are formed in opposite directions to each other, and axes X1 and X2 of the crushing rollers 21a and 21b are opposite Thereby generating friction with the grain grains and pulverizing and pulverizing them. More preferably, the teeth of the pair of crushing rollers 21a and 21a have mutually different twist angles (A DEG, B DEG). For example, a twist angle of 13 [deg.]: 15 [deg.].

On the other hand, in the present system, powdered pulverized powder is collected through a total of three first to third body type detectors (31, 32, 33) installed between the first to fourth pulverizers (21, 22, From which grains can be further sieved to sieve roughly ground grains, powdered grains, and the like. Therefore, the first to third body-shake detectors 31, 32, and 33 have different sights.

The three body type separators 31, 32, and 33 have the same structure, and any one of them will be described with reference to FIG. 3 to FIG.

As shown in Figs. 3 to 6, any one of the body gauges 31 includes a selector frame 301 having a plurality of support legs 301a and a pair of pivotal support plates 302b stably installed thereon, (302) having an upper end inserted into a pair of bar support plates (302b) and a lower end disposed nearer to the bottom of the selector frame (301) and arranged at least in four places, A mesh box lower pedestal 303 suspended horizontally and arranged horizontally and a mesh box upper pedestal 305 fixedly disposed at a predetermined height from the mesh box lower pedestal 303 via a connecting bar 304, A mesh box 306 for constituting a plurality of grains which is layered and stacked so as to be taken out between the mesh box lower pedestal 303 and the mesh box upper pedestal 305, A vibration motor 307, A horizontal vibration eccentric rotation body 308 which is rotatably installed at the center of the lower bottom surface of the mesh box lower pedestal 303 and rotates by receiving the rotation force of the horizontal vibration motor 307 by the belt 307a, An upper and lower vibration motor 309 fixedly disposed at the center of the upper surface of the box upper pedestal 305, an up and down vibration eccentric rotation body 310 eccentrically connected to the rotary shaft of the up and down vibration motor 309, And upper and lower vibration springs 311 and 312 which are inserted into upper and lower portions of the mesh box 306 for constituting the grain to allow the vertical vibration of the grain box 306 to be constantly displaced and to support the mesh box 306 by an elastic force.

The support legs 301a are composed of four, but the number is not limited to this. The support legs 301a may be connected to each other through a cross bar or the like which is not shown but installed in a horizontal or diagonal direction.

The vibrating bar 302 is made of a long steel having a circular cross section. The vibrating bar 302 may be disposed at least at four positions in at least one position, with the upper end inserted into the pair of bar support plates 302b and the lower end positioned near the bottom of the selector frame 301. [ In the present embodiment, the pivoting rods 302 are installed in one pair at one location, and a total of eight pivoting rods 302 are installed.

Therefore, when the horizontal vibration motor 307 and the vertical vibration motor 309 are driven to rotate at the same time, a plurality of layered grain boxes 306 for constituting a grain are horizontally (in the H direction) and vertically (in the V direction) . As a result, the pulverized raw material fed into the mesh box 306 for constituting the uppermost grain is sifted downward sequentially in the grain box 306 for sifting the grain.

When the horizontal vibration motor 307 is rotationally driven, the horizontal vibration eccentric rotation body 308 rotates away from the center of the rotation axis of the mesh box lower pedestal 303, so that the mesh box lower pedestal 303 rotates in the horizontal plane . This causes the mesh box 306 for constituting a plurality of layers to be layered between the mesh box lower pedestal 303 and the mesh box upper pedestal 305 to rotate in a horizontal plane. At this time, the vibration bar 302 serves to support the mesh box 306 on the selector frame 301 at the time of vibration of the plurality of grain boxes 306 including the mesh box lower pedestal 303 and the mesh box upper pedestal 305 .

At the same time, the center of gravity of the up-and-down vibration eccentric rotation body 310 is repeatedly moved up and down so that the upper and lower vibration springs 311 and 312 are stretched and contracted, A plurality of mesh boxes 30 for constituting grains layered one on another between the mesh box lower pedestal 303 and the mesh box upper pedestal 305 are vertically horizontally oscillated .

Here, the mesh box 306 for constituting the grain is constituted by a lower netting 3100 and an upper netting 3200 disposed on the upper portion of the lower netting 3100 as shown in FIG. The lower mesh body 3100 includes a lower mesh reinforcement frame 3101 having a rectangular cross section and a rectangular band shape, a split partition plate 3102 for dividing the inner area of the lower mesh reinforcement frame 3101 into a plurality of portions, And a lower net 3103 provided on the inner bottom surface of the lower panel 3101. The upper net member 3200 includes an upper mesh reinforcement frame 3201 having a rectangular cross section and a rectangular band shape and an upper net 3202 provided on an inner bottom surface of the upper mesh reinforcement frame 3201.

Therefore, the raw material of the grain is sieved in the upper netting 3202 of the upper netting 3200 and the secondary netting 3103 of the lower netting 3100 after the primary sieving.

6 and 7A, the lower net member 3100 is provided with a plurality of vibration balls 3300 which are positioned in the respective divided regions divided by the partition plate 3102 and perform free rolling and vertical vibration motion in the corresponding region desirable. For example, two or three vibration balls 3300 may be installed in one partition. The vibrating ball 3300 may be made of rigid metal material or metal or hard plastic that does not break well into a spherical shape.

Therefore, when the vibrating ball 3300 is installed, the vibrating ball 3300 vibrates up and down together with the vertical vibration (V direction) of the mesh box 306 for constituting the grain as shown in FIGS. 7A and 7B, It is possible to increase the constitutional effect by eliminating clogging of the mesh eye by repeatedly hitting it.

1, the step of separating and removing the impurities contained in the pulverized product by using the first centrifugal adsorption separator 18 provided between the first body separator 31 and the second pulverizer 22 Can be added.

Finally, a step of separating and removing the impurities contained in the pulverized product using the second centrifugal adsorption separator 19 may be added between the first body separator 31 and the third pulverizer 23.

Here, the first centrifugal adsorption separator 18 and the second centrifugal adsorption separator 19 have the same configuration. Accordingly, when a centrifugal airflow is formed by a swirl in the inside of a centrifugal adsorption separator 18, a light material (grain shell, dust, and other impurities that receive low gravity) is discharged under centrifugal force, Only the granular material of the material is descended by heavy gravity.

Reference numerals 1 to 6 and 9 denote "cyclone", reference numerals 7, 8, 9a and 9b denote blowers, and reference numeral 305a denotes a pulverized water inlet.

As described above, according to the present invention, the body type separator receives the vertical vibration together with the horizontal rotational vibration, and the constitution ability of the grain particles ground through the crushing roller is improved and the particles are efficiently separated. In addition, since the vibrating balls are included in the body type separator, clogging of the eyes is eliminated and productivity is improved.
