Description

Grain stripping method and its stripping device with excellent milling yield

The present invention relates to a grain stripping method and a stripping device having excellent milling yield. Specifically, only grains (rice and rice stripped grains) which have not been stripped by using a brown rice sorting means (color sorter or brown rice color sorter) are returned to the brown rice. This is to improve the processing and degreasing performance of the brown rice and to reduce the breakage of grain, thereby significantly improving the mill yield and quality.

In general, the stripping or milling process is essential for processing grains such as rice. For example, in the case of rice, the rice husks are removed using a brown rice machine, then the brown rice of the good is separated by a brown rice separator, and then transferred to a subsequent line (following process) to be processed and weighed into white rice.

1 is a block diagram of a conventional grain peeling apparatus 1, and a stone separator 2 for removing stones and foreign substances contained in a raw material (rice) to be introduced, and a rice husk (shell) of rice from which stones and foreign substances have been removed. Brown rice grinder (3) to make, rice husks to remove chaff from rice, brown rice, and chaff introduced from the brown rice machine (3), and brown rice separator for sorting brown rice from which rice husks have been removed and unsepared rice (5) ), A chungcheong separator (6) for removing unrefined brown rice (blue tooth) contained in the brown rice separated and separated by the brown rice separator (5), and a brown rice erection machine for separating and removing stones and foreign matters in the chungcheok selected brown rice ( 7), the rice polisher 8 which peels off the bran layer (surface) of brown rice by rubbing and / or grinding method, and turns it into white rice, and the rice grinder 9 which removes the rice bran and the foreign material, etc. of the polished rice surface. And a vibrating separator 10 for removing rice lumps and foreign matters contained in white rice and different colors from white rice. It includes a color sorting and foreign matter sorter 11 for separating (selecting) and removing foreign matters, colored grains, and damaged grains, and an automatic weighing packing machine 12 for packaging while weighing the selected white rice at a predetermined capacity.

FIG. 2 illustrates a process of returning the brown rice and the undegreased rice separated by the brown rice separator 5 back to the brown rice machine 3 to detach the rice. The precipitated rice is the first conveyor C1. The rice bran is stripped and then removed by the chaff bulge (4), and the rice bran is stripped through the hopper (H1) and the rice bran stripped brown rice and rice stripped rice (rice husk remaining in a portion of brown rice) Is put into the brown rice separator (5) via the second conveyor (C2) and the hopper (H2) to separate the brown rice and rice stripped rice, and the brown rice of the separated good is transferred to the subsequent line, processed and weighed into white rice .

On the other hand, in the brown rice separated by the brown rice separator (5) there is a large amount of rice stripped rice is mixed, so de-aerated is required to return to the brown rice (3) via the third conveyor (C3) and the hopper (H1) again. (Secondary) The disassembly process will take place.

That is, a large number of brown rice to be transferred to the subsequent line is being returned to the brown rice (3), which is desirable to ensure that the rice hull in the brown rice separator (5) to return only the rice stripped rice, but it is impossible to separate only the rice In the sorting plate of the brown rice separator (5), both the rice and the brown rice are mixed in a certain section. At this time, the amount returned is 20 to 30% of the total amount separated by the brown rice separator (5), 85 to 95% of the amount returned to the brown rice (3) is brown rice with rice hulls detached, unriceped rice Is 15 ~ 5%, which corresponds to a small amount, resulting in the following problems.

First, the quality of brown rice is greatly degraded. That is, the brown rice separator 5 cannot separate only grains which are not detached by the sorting plate, and separates the sections in which the shells are detached from the grains separated by the sorting plate and the sections in which the grains are not detached. Since all the mixed sections are returned to the brown rice (3), the already removed shelled rice passes through the roller (ROLLER) of the brown rice (3) in double and triple, and the wound and cracks are generated by pressure and twist. Brown rice breaks or cuts in post-processing, resulting in lower yields and significant economic losses.

For example, 85% to 95% of the brown rice returned to the brown rice machine 3 receives damage (pressure) while passing unnecessarily through the high-pressure stripping roller, and the yield is greatly reduced while the rate of cutting off is significantly increased. In addition, since cracking occurs in brown rice, it is changed to cutting or wrapping in the post-process which is subjected to pressure such as rice milling, so that the milling yield and quality (quality) are greatly reduced. For example, when producing about 7 tonnes of brown rice per hour, about 2.3 tonnes of brown rice and undegreased rice are being returned to the brown rice machine (3), which greatly reduces the milling yield and quality.

Second, brown rice production is reduced by 20-30% due to the large amount of unneeded reversion. For example, when producing about 7 tons of brown rice per hour, the yield of about 2.2 tons per hour is reduced and the road yield is greatly reduced.

Third, there is a problem in that energy (power) is wasted unnecessarily by the return stripping.

The present invention, by using only the brown rice sorting means (color sorter or brown rice color sorter) to return only the undegreased rice (a small amount of rice) to the brown rice so that the complete detachment to increase the processing capacity and detachment performance of the brown rice and reduce the breakage of grain An object of the present invention is to provide a method for stripping grains and a stripping device having excellent milling yield, or a high yield and good quality.

Grain stripping method of the present invention comprises the steps of: a) detaching the husks of rice using brown rice, b) removing the husks stripped with chaff, and c) separating and separating rice and brown rice with a brown rice separator. And d) screening the primary color by mixing the rice and brown rice with a color sorter, and e) sorting the second color by returning the defective color screened to the color sorter, and f) sorting the second color. The defective product may be returned to the brown rice and the good brown rice is returned to the color sorter to sort again, and g) transferring the first and second color-selected good brown rice to the subsequent line.

Grain stripping method of the present invention, a) step of removing the husks (rice husk) of rice using brown rice, b) removing the husks (chaff) stripped with chaff, c) rice (or rice without rice) ) Separating and browning rice, and d) Determining a mixture of rice (or rice and rice) and brown rice, but transfer the brown rice of the good to the subsequent line and transfer rice (or rice and rice) and brown rice. The mixed product is transferred to a color sorter (or brown rice color sorter), which is a means of brown rice sorting, e) a step of sorting brown rice with a color sorter, and a step of sorting a rice and brown rice blend with a color sorter, f) color The rice and brown rice mixed product is sorted by a sorter, but if it is a defective product containing rice and rice without rice by sorting, the rice is returned to the brown rice so that the rice and undeparted rice are detached and transferred to the subsequent line if the rice is not defective. After processing processing It may include the step.

Grain stripping method of the present invention, A) step of removing the husks (rice husk) of rice using a brown rice, B) removing the husks stripped with chaff, C) separating and separating rice and brown rice, D ) Judging the mixed product mixed with rice and brown rice to determine that the good brown rice is transferred to the subsequent line, E) screening the brown rice by color sorter, F) screening the first stage by color sorter, G) color sorter 2 stages of screening, H) 3 stages of screening with color sorter, I) Determination of rice and devital rice and good brown rice, return rice and devital rice to brown rice and good quality brown rice to be transferred to the next line J) transferring the good quality brown rice to a subsequent line.

In the grain stripping method of the present invention, in the grain stripping method of removing and removing rice husks of rice using a brown rice machine and then screening rice and brown rice with a brown rice separator; A color sorter may be installed at the rear end of the brown rice separator to select rice and rice without rice and brown rice selected by the brown rice separator, but only rice and rice without rice are returned to the brown rice so that they can be completely detached.

The precipitated rice is transferred to the rice mill 3 via the first conveyor C1 and the hopper H1. The rice husks are thrown away and then removed by the rice husks (4). The rice and rice stripped rice husks are introduced into the brown rice separator (5) via the second conveyor (C2) and the hopper (H2). Wawa rice stripped rice is separated, the brown rice of the good separated by the brown rice separator (5) is transferred to the subsequent line through the eighth conveyor (C8), processed and weighed into white rice, containing rice and rice stripped rice The brown rice is transferred to the color sorter (13) and sorted again, 7 It is returned to the brown rice machine (3) via the conveyor (C7) and the hopper (H1), completely dismounted, and then transferred to the subsequent line through the chaff bulge (4) and brown rice separator (5). Rice and brown rice are returned to the color sorter 13 firstly via the sixth conveyor C6 and are sorted secondly. Rice and brown rice not sorted out of the unleaded rice are sorted out via the fifth conveyor C5. (13) is returned to the second stage and the third screening, the final good brown rice is transferred to the subsequent line through the eighth conveyor (C8) and is unsaturated contained in the brown rice of the good by the post-process, for example, the clarifier 6 Brown rice (blue tooth) is removed, stones and foreign matters in the brown rice selected for clarification by the brown rice crusher (7) are separated, and a layer of the brown rice (surface) that is precipitated by friction and / or polishing by the rice mill (8). White rice coated with white rice while being stripped) The rice bran and foreign matters on the surface are removed, and the rice lumps and foreign matters contained in the white rice are removed by the vibrating separator 10, and the foreign matters and colored granules different from the white rice and color by the color sorter and the foreign matter sorter 11 are removed. Damaged grains and the like are separated (selected), and the white rice, which is color-selected by the automatic weighing packing machine 12, is automatically packaged while being weighed at a predetermined capacity.

Reference numeral V1 (V2) is a direction switching valve, G is a gate provided under the hopper (H1) (H2).

The present invention is to remove the rice and the rice unseparated by the color sorter 13 only to return to the brown rice (3) via the seventh conveyor (C7) and the hopper (H1) again (second) detaching process As it is completely dismounted during the process, the milling yield is greatly improved and quality deterioration is prevented.

In other words, the brown rice and rice (nude or rice stripped rice) are completely separated by the color sorter 13, and the brown rice of the separated and sorted good products is transferred directly to the subsequent line without being returned to the brown rice machine 3 to undergo a post-process. Only about 5 ~ 15% of rice and non-thick rice are returned to the brown rice machine (3) and completely removed so that the milling yield (productivity) is greatly improved, and cracking, cutting, and wrapping do not occur. ) Is largely shaped, and energy, cost and time are saved as the amount of return is reduced.

In the present invention, the yield is increased by increasing the quality of brown rice. In other words, by eliminating brown rice return, the brown rice yield is increased, and the white rice yield is increased due to the reduction of envelopment. For example, in the case of a line producing 7 tons of brown rice per hour, only about 70 to 310 kg of rice is returned per hour, so that no return of about 2 tons of brown rice is produced. Accordingly, there is an advantage in that the production yield, for example, the mill yield is greatly improved, the amount of return is reduced and the energy (power) consumption is reduced.

The present invention is intended for the sake of convenience of description, but can be applied to the stripping process of all grains including 'rice'.
