Description

[Detailed description of the invention] The present invention relates to improvements in pigeon wheat milling equipment.

Conventional wheat milling is based on the principle of using a grinding-type grain miller to mill the wheat grains that have been removed through the gaps between the rolls of a roll-type miller. In pigeon wheat, which has irregular grains and a hard husk, during the above-mentioned de-processing process, there is frequent shedding of spots due to the pressure difference that each grain receives, and a large amount of broken grains, damaged grains, etc. are produced due to the forced grinding process. This has the disadvantage of significantly lowering the quality of refined barley grains.

In order to eliminate the above-mentioned drawbacks, the present invention provides a specific gravity sorting device consisting of a porous wall sorting plate with a wavy surface formed by a large number of mountain veins in the downstream stage of an impact type desorting device. By forming an integrated process with a water-addition friction type grain milling device,
The centrifugal shedding effect minimizes shedding during the shedding process, and the specific gravity shaking sorting effect eliminates damaged grains, immature grains, broken grains, and other incomplete grains to make the processed pigeon wheat uniform. By removing grains with added moisture and polishing them completely into beautiful white grains using frictional whitening, we can reliably, smoothly and quickly produce carefully selected pigeon barley that is high in protein and high in fat and is a high quality health food. The aim is to develop and provide high-precision equipment for mass production.

Next, the porous wall sorting plate 43 will be explained with reference to FIG. The sorting plate 43 has a porous wall plate provided with countless through holes 59 formed into a wavy surface F by a large number of chevron-shaped veins 60, and one side of the longitudinal plate edge of the veins 60 of the sorting plate is open. A discharge port H is provided, and a side wall 61 surrounding the other three-directional plate edge is provided, and the discharge port H is provided with a grain size discharge port 62, a mixed grain discharge port 63, and a damaged grain discharge port 64. It is joined to the sorting plate and integrally formed into the sorting frame G.

Because of the above-mentioned configuration, the supply hopper 2 of the removal section D provided in the impact-type removal sorting device A for raw pigeon wheat.
1 and starts the device, the pigeon oats flow down onto the rotating disk 24 that rotates at high speed, and are injected laterally by the centrifugal injection blades 25 arranged radially on the surface of the plate 24. It collides with the surface of the annular shock absorbing plate 26, and the hard hull of the pigeon wheat bursts and escapes due to the impact force. It is carried into the supply port 29 of the wind selection section E through the filter. In the machine box 28 of the wind sorting section E, the grains are sorted by the wind flowing in the direction of the arrow in the figure through the sorting air passage 36, and the shattered and unshelved grains are sent to the mixed grain receiving trough 37, and the immature grains are sent to the immature grain receiving trough. 3
The grains in the mixed grain receiving trough 37 are carried out by the screw conveyor, and
The grains are fried by the elevator 40 to the supply hopper 41 on the side of the specific gravity sorter B, and the immature grains in the immature grain receiving trough 38 are discharged outside the machine, and the lightweight wheat husks are provided at the end of the sorting air path 36. The dust is conveyed in flight from the dust exhaust port 31 via the exhaust fan 32 to the dust collector 34, where it is separated and collected. Then, while the grains fried in the supply hopper 41 of the specific gravity sorter B flow down the air sorting chamber 58, lightweight impurities are re-sorted and removed, and the re-sorted wheat grains are placed in the airtight machine frame. It flows down to the sorting frame G in 42 and is supplied. And the wheat grain is porous wall sorting board 4
A flat grain layer is formed as it flows down the slanted wavy surface F of No. 3, and damaged grains with low specific gravity (including crushed grains, etc.) are deposited on the upper surface of the grain layer by the blast action from the porous wall surface. At the same time, the grains with high specific gravity gather on the bottom surface of the grain layer and
Due to the longitudinal vibration of the wavy surface F, the grains on the bottom surface of the grain layer are pushed up to the front and higher side and drift laterally to form a grain size flux P. The floating damaged grains drift laterally while sliding backward on the upper surface of the sized grain to the damaged grain flux R.
A mixed grain flux Q of sorted grains and damaged grains is formed between each of the fluxes P and R, and each flows out to the discharge port H in the final stroke of the sorting plate, and a mixed grain flux Q is formed between the fluxes P and R. Grain sorting outlet 62, mixed grain outlet 63, damaged grain outlet 64
The sorted particles of each flux P, Q, and R flow down to the supply hopper 20 of the grain milling device C in the next stage for grading.
The mixed grains are returned to the wind sorting section of the de-sorting device A, and the damaged grains are returned to the removing section D of the de-sorting device A. In the water-friction type grain milling device C, the sized grains (de-malted grains) in the supply hopper 20 flow into the milling chamber 4 by the rotation of the tube shaft 3. The water flowing out from the air pipe 18 is turned into ultrafine water particles by the compressed air flowing from the blast pipe 18, and flows into the chamber 4 through the ventilation holes 8 of the tube shaft 3 and the slots 7 of the friction type whitening trochanter 2. The wheat grain is sprayed onto the grains, and the moment the hard wheat grain surface is softened by adding an appropriate amount of moisture, the wheat grain epidermis is peeled off, and at that moment, the bran powder generated by ventilation is transferred to the outside of the whitening chamber 4 with the porous wall of the whitening cylinder. While removing and polishing the grains, the grains are milled into beautiful white grains, which are then discharged from the machine through the rice discharge port 6 and handed over to the next line. FIG. 4 is a diagram showing a second embodiment of the present invention, and in the polishing of grains whose outer cortex has aromatic properties, a grinding device is used between the grain polishing device C and the specific gravity sorting device B. After peeling off and separating the outer cortex in a non-humidified state through the grinding action of the grain milling machine J, the surface of the particles is subjected to a friction-type grain milling machine C that adds water.
The grains are polished with water and milled into beautiful white grains.

As described above, the pigeon wheat grain milling device of the present invention is provided with a specific gravity sorting device consisting of a porous wall sorting plate formed on a wavy surface by a large number of mountain veins in the downstream stage of the impact type de-sorting device, and By installing a water-friction type grain milling device in the process to form an integrated process,
Cocoon wheat with a relatively large particle size, uneven grain size, and hard hull is injected by the centrifugal injection blade of the high-speed rotating disk of the impact-type de-sorting device, and collides with the de-impact wall. Compared to conventional derolling with a fixed gap, which uses compression friction, the crushing force is increased and the hard shell can be easily removed, and it is not affected by irregularity in particle size. In addition, damaged grains, broken grains, etc. are removed, carefully selected, and the grains are sized by the specific gravity swinging sorting action of the porous wall sorting plate on the wavy surface of the specific gravity sorting device. It is possible to improve the quality of processed pigeon wheat by supplying it to the grain milling process to make the processed pigeon grain uniform, and also to inject ultrafine water particles onto the grain surface in the milling chamber of the water-friction type grain milling device, which requires less forcing force. Because it is refined by frictional whitening,
The hard wheat grain surface is softened by adding an appropriate amount of water, and the wheat grain skin layer is peeled off at the moment, and at that moment, each grain surface is polished while removing the generated bran powder through the porous wall and out of the polishing cylinder through ventilation. The present invention is capable of completely milling beautiful whitened barley grains, and has remarkable effects such as always reliably and smoothly mass-producing carefully selected pigeon barley as a high-quality nutritional food.
