Description

Rice processing system with brown rice separator omitted and its processing method}

The present invention relates to a comprehensive rice processing system and a processing method thereof, in which a brown rice separator is omitted, and in detail, a color sorter (or brown rice color sorter) is installed instead of the brown rice separator installed immediately after the rice hull fan to remove the grain (rice Alternatively, only uncut rice, etc.) can be color-selected, and then returned to a brown rice machine so that it is completely detached, thereby greatly improving the processing power and removal performance of brown rice, and reducing the damage of grains, thereby greatly improving the milling yield and quality of rice.

In general, in the process of processing grains such as rice, a peeling or reproducing (brown rice production) process is essential. For example, in the case of rice, rice hull, which is the husk of rice, is removed using a brown rice machine, and then the rice hull is removed with a rice hull pan, and a brown rice separator is installed at the rear end of the rice hull pan to return the undisassembled rice to the brown rice machine.

The brown rice separator separates mixed brown rice and uncut rice by shaking the sorting plate in order to sort the uncut rice (or rice), but cuts a certain section where the uncut rice is collected using the sorting plate and returns it to the brown rice machine. At this time, about 75-85% of the amount returned to the brown rice machine is already stripped brown rice. At this time, as the returned brown rice is removed again by the microscopy machine, wounds and cracks occur due to pressure and torsion, and the damaged brown rice is broken or cut off in the post process, leading to a decrease in yield, resulting in considerable economic loss.

In addition, when the husk of rice is removed, the surface of brown rice is relatively smoother than the outer surface of the rice. The principle of the brown rice separator is to shake the uneven-shaped sorting plate to spread the brown rice mixed with rice flat on the sorting plate to separate the rice with different surface roughness to one side. At this time, it is impossible to separate 100% of only uncut rice, and about 75-85% of uncut brown rice is included in the section with uncut rice.

On the other hand, in the case of the rice hull processing plant, the process of removing rice (reproduction process) consists of (arrangement) one brown rice and one rice husk on one line, or constructing one rice husk on two rice hulls on one line. It is common. Of course, in the case of configuring two brown rice machines, a type of rice husk punggu with a large throughput is selected, and the production of brown rice is generally about 3.5 to 7 tons per hour. At this time, a model with an appropriate processing capacity is selected according to the processing amount of the brown rice separator.

In this way, all grain peeling processes cannot achieve 100% peeling at a time using a brown rice machine, so the unshattered rice is returned to the brown rice by using a brown rice separator and re-dispatched, resulting in a decrease in yield and quality degradation. All of the grain stripping processes are operated in the same way as described above, so the amount of grain lost is truly enormous.

1 is a block diagram of a conventional rice processing system 1 installed in a rice processing plant, a stone removal machine 2 for removing stones and foreign substances contained in an input raw material (rice), and rice husks (shell ), the rice hull punggu (4) that removes the rice husk from the rice, brown rice, and rice husk discharged from the brown rice machine (3), and the brown rice from which the rice hull has been removed, and the rice hull that has not been removed from the rice husk. A brown rice separator (5) that sorts and returns some of it to a brown rice machine (3), and a cheongchi sorter (6) that removes unripe brown rice (blue rice) contained in the brown rice separated and sorted by the brown rice separator (5). , A brown rice stone erection machine (7) that separates and removes stones and foreign substances from the selected brown rice, and a rice milling machine (8) that peels off the bran layer (surface) of the brown rice by rubbing and/or polishing the precipitated brown rice and polishes it into white rice. , A tailing machine (9) that removes rice bran and foreign substances from the surface of polished rice, a vibrating separator (10) that removes rice lumps and foreign substances contained in the polished rice, and foreign substances and colored particles different in color from the polished rice. It includes a color sorting and foreign matter sorting machine 11 for selectively removing the etc., and an automatic weighing and packaging machine 12 for weighing and packaging the color-selected white rice in a predetermined capacity.

FIG. 2 is a diagram showing a process of removing the brown rice separated by the brown rice separator 5 and the rice stripped again by returning the rice to the brown rice machine 3 to remove the rice from the first conveyor (C1) The rice hull is peeled by entering the brown rice machine (3) via a hopper (H1), and then removed by the rice husk fan (4), and the second conveyor (C2) and hopper ( H2) is put into the brown rice separator (5) to separate the brown rice and uncut rice, and the separated good-quality brown rice is transferred to the post process to be processed and weighed and packaged into white rice.

On the other hand, among the brown rice separated by the brown rice separator 5, uncut rice is mixed in a large amount, so it is necessary to remove the rice, so it is returned to the brown rice machine 3 via the third conveyor (C3) and the hopper (H1). (Secondary) You will go through the process of dismounting.

That is, a significant number of brown rice to be transferred to the subsequent line is being returned to the brown rice machine (3), which is desirable to select and return only the undismounted rice that has not been stripped in the brown rice separator (5), but only the rice is sorted and separated. Since it is impossible to do so, all of the predetermined section in which rice (nu) and brown rice are mixed is returned in the sorting and separating plate of the brown rice separator (5). At this time, the amount of water returned to the brown rice machine (3) amounts to 20-30% of the total volume separated by the brown rice separator (5), and 85-95% of the volume returned to the brown rice machine (3) is brown rice from which rice husk has been removed. And, the amount of unpicked rice is 15 to 5%, which is a small amount, and the following problems occur accordingly.

First, the quality of brown rice is greatly reduced. That is, the brown rice separator (5) cannot separate only the grains that have not been removed by the screening plate, and the section where the uncut grains are mixed by separating the grain section with the peeled off and the section in which the unsplit grains are mixed on the screening plate can be separated. All of them are returned to the brown rice machine (3), so the brown rice from which the skin has already been removed passes through the rollers of the brown rice machine (3) in double and triple, causing scratches and cracks due to pressure and torsion. Breaking, cutting rice, and wedges are generated in the post-process, leading to a decrease in yield, resulting in considerable economic loss. For example, 85-95% of brown rice returned to the brown rice machine 3 is damaged (pressure) while passing through a high-pressure stripping roller unnecessarily, resulting in a significant increase in the generation rate of rice harvesting and wedges, resulting in a significant decrease in yield. In addition, as cracks occur in the brown rice, it changes into rice-saving rice and serrata in a post-process under pressure such as rice milling, so the yield and quality (quality) of milling are greatly reduced. For example, in the case of producing about 7 tons of brown rice per hour, about 2.3 tons of brown rice and uncut rice are returned to the brown rice machine (3), so the milling yield and quality are greatly reduced.

Second, the production of brown rice is reduced by 20-30% due to the unnecessary return of a large amount of brown rice. For example, in the case of producing about 7 tons of brown rice per hour, the production yield of about 2.2 tons per hour is reduced, and the yield of milling is greatly reduced.

Third, there have been several problems such as unnecessary waste of energy (power) due to reversal escape.

7 is a configuration diagram of the main parts of the grain peeling device shown as an example of the present invention, a mixture of uncut rice and brown rice milled by a brown rice machine 3 is color-selected with a color sorter 13, and then the brown rice of a good product is a subsequent line. It shows the process of transporting and removing the uncut rice by returning it to the microfluidic machine (3), and the precipitated rice is passed through the first conveyor (C1) and the hopper (H1) through the microfluidic machine (3). After the rice husk is peeled from the rice husk, the peeled rice husk is removed by the rice husk fan (4), and the brown rice and rice peeled rice from which the rice husk has been peeled is passed through a second conveyor (C2) and a hopper (H2), and a color sorter (13). ), the brown rice and uncut rice are color-selected, and the selected brown rice is transferred to a subsequent line through the 7th conveyor (C7) to be processed and weighed and packaged into white rice. It is returned to the microscope (3) via the conveyor (C6) and the hopper (H1), completely removed, and then transferred to the next line through the rice husk fan (4), the color sorter (13) and the seventh conveyor (C7), Uncut rice and brown rice that could not be sorted during the sorting process are first returned to the color sorter (13) via the fifth conveyor (C5) and hopper (H2), and are secondarily sorted. The and brown rice are secondarily returned to the color sorter 13 via the second conveyor (C2) to be screened for the third time. The unripe brown rice (cheongchi) contained in the fine brown rice is removed by the sorting machine 6, stones and foreign matters in the brown rice sorted by the brown rice stone erection machine 7 are separated and removed, and the rice milling machine 8 removes them. The bran layer (surface) of the brown rice precipitated by friction and/or polishing is peeled off and polished to white rice, the rice bran and foreign matters on the polished rice surface are removed by the polishing machine 9, and the vibration separator 10 Rice lumps and foreign substances contained in the white rice are removed, foreign substances different in color from the white rice, colored grains and damaged grains are separated (sorted) and removed by a color sorting and foreign matter sorting machine (11), and automatic weighing and packaging machine (12) The white rice selected by color is automatically packaged while being weighed in a predetermined amount.

Non-explanatory symbols (V1) and (V2) are directional valves.

In the present invention, only the uncut rice, which has been color-selected by the color sorter 13, is returned to the microscope 3 via the sixth conveyor (C6) and the hopper (H1), and re-disassembling (secondary) while going through the process. Since it is completely detached, the milling yield is greatly improved and quality deterioration is prevented.

In other words, brown rice and rice (nu or uncut rice) are completely separated by color sorting by the color sorter 13, and the separated and sorted brown rice is transferred directly to the next line without returning to the brown rice machine 3. After going through the process, only about 5 to 15% of uncut rice is returned to the brown rice machine (3) and completely detached, thereby greatly improving the milling yield (productivity). Quality) is greatly improved, and energy, cost, and time are saved as the amount of returned goods decreases.

Instead of omitting the brown rice separator, the present invention uses a color sorter (or brown rice color sorter) 13 to select only rice and unsplit rice and return it to the brown rice machine 3 so that it is completely stripped, thereby improving the quality of brown rice. The processing capacity and detachment performance of the group (3) are greatly improved, and profits are generated by increasing the yield.

In other words, by eliminating the return of brown rice, the yield of brown rice increases, and the yield of white rice increases due to the decrease in the occurrence of white rice, which improves the quality of the rice, the production volume is greatly increased, the milling yield is greatly improved, and the amount of return is reduced, resulting in energy (power) consumption. There are advantages such as being reduced.

In the present invention, since the configuration of the brown rice separator installed immediately after the rice hull fan and its subsidiary equipment (bucket conveyor, electrical equipment, etc.) is omitted, equipment cost, construction cost, maintenance cost, operation cost, etc. are greatly reduced, and installation space is also reduced. There is an advantage to be taken.

Although the present invention has been aimed at'rice' for convenience of explanation, it goes without saying that it can be applied to the peeling process of all grains including'rice'.
