Description

  The present invention relates to a germ separation and recovery apparatus for taking out germ from rice bran generated during a rice milling process.

Conventionally, a configuration in which a pair of mesh filters are arranged in series in a suction air passage of a blower and an electric dust collector is provided between the filters arranged in series is well known (Patent Document 1). .

Since the known example is configured to remove the koji adhering to the brown rice that has already been separated from the koji in the rice milling process, the powdered germ is separated from the koji of the powder adhering to the brown rice. However, there is a problem that it is not possible to obtain “grain germ” with high commercial value.
In other words, the rice bran produced during the rice milling process is approximately 10% of the weight of brown rice, so if “1 屯” brown rice is milled, the rice bran is produced in units of “approximately 100 kg”, and germs are produced from this large amount of rice bran. In the sorting, there is a problem that the working efficiency is very low in the configuration of sorting using a known example filter and dust collector.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a germ separation and recovery device. Although not shown in the drawings, germs in rice bran generated in the rice milling process of one or more rice milling devices arranged in parallel to polished rice In addition to sorting and separating the rice, it is discovered that sizing that should not be mixed in the rice bran in the milling process is found.
In the milling process, when brown rice is refined, there are two types: one that is crushed into a powder and mixed into the koji, and one that is separated from the brown rice grains in the form of granules. It separates and separates the mixed granule grains.
Therefore, the composition of the rice milling process is arbitrary. Originally, germs in the shape of granules are mixed in the rice bran, but the germ parts in the shape of granules from the brown rice grains are positively mixed in the rice bran. If constituted, the efficiency of germ collection is improved, which is preferable.
Strictly speaking, powder wrinkles are formed by particles and are included in the granules. In this application, wrinkles that cannot be recognized at a glance by the naked eye are used as powders, and germ particles that can be recognized as particles by the naked eye. It is a granule.

In the germ separation and recovery apparatus 1, a terminal end of a straw transporting supply cylinder 3 to which the straw discharged from the one or a plurality of rice mills is supplied is connected to an upper part of a square box-like case (frame) 2.
In case 2, there is a primary sorting device (powder granule sorting device) that separates the powdered koji, and the sized particles (G) and small rice (C, including crushed particles) and germ particles (H) mixed in the koji. ) 5 is provided. The primary sorting device 5 performs suction sorting between the soot supply port 6 of the case 2 connected to the soot conveyance supply cylinder 3 and the soot suction discharge port 7 provided so as to face the opposite side of the soot supply port 6. An air passage (primary sorting air passage) F is formed, and in the suction sorting air passage F, powdery cocoons, granule sizing and small rice and germ grains are primarily sorted.
Reference numeral 8 denotes a transfer conveyor provided in the basket transfer supply cylinder 3.

The primary sorting device 5 is formed by a primary sorting dropping port 10 that drops sized grains in rice cake, small rice, and germ grains using falling in descending order by specific gravity, and the primary sorting dropping port 10 is sucked and sorted. It is formed in the air path F.
The primary sorting and dropping port 10 opens to the upper part of the primary guide rod 14 formed by the left and right side plates 9 of the case 2, the front falling plate 12 fixed to the left and right side plates 9, and the rear flowing plate 13. Is optional.
The side close to the cocoon supply port 6 below the primary sorting and dropping port 10 is a sized particle dropping flow channel 15, and the cocoon suction and discharging port 7 side is a germ falling channel 16, and the sized particle dropping channel 15 and the embryo falling flow are In the middle of the path 16 is a small rice broken rice falling flow path 17, which not only sorts powder and granules, but also sizing particles that fall on the side close to the soot supply port 6 and falls to the soot suction discharge port 7 side. Expected to be separated into germs that fall and small rice / crushed rice that falls between them.

In addition, the front-side falling plate 12 and the rear-side falling plate 13 are also formed so that the distance between the front-side falling plate 12 and the rear-side falling plate 13 becomes narrower as it goes down, expecting the action of collecting the dropped germ grains. Is not a requirement.
Moreover, the partition plate 18 which divides each flow path is provided between the sized particle fall flow path 15 and the small rice-crushed rice fall flow path 17 and the small rice-crushed rice so that the germ separated at the primary sorting drop opening 10 does not mix with others. Providing each between the drop channel 17 and the germ drop channel 16 is preferable because the sorting accuracy is further improved.

Accordingly, a guide inclined plate 20 for guiding the supplied soot to the primary sorting and dropping port 10 is provided in the case 2 facing the soot supply port 6.
That is, the soot suction discharge port 7 is provided at a relatively low position with respect to the soot supply port 6 so that the suction sorting air passage F can be blown obliquely downward in the case 2 to efficiently perform the wind selection of the germ particles. In this manner, a predetermined interval is provided between the soot supply port 6 and the front flow-down plate 12 of the primary sorting drop port 10, and a guide inclined plate 20 is provided above the front flow-down plate 12.

The guide inclined plate 20 adjusts the inclination angle of the guide inclined plate 20 according to the conditions such as the amount of soot supplied and the mixing ratio of the granules, thereby improving the wind selection efficiency.
The inclination angle adjustment of the guide inclined plate 20 is arbitrary, but in the embodiment, the horizontal shaft 21 is fixed to the base of the guide inclined plate 20, and the horizontal shaft 21 is attached to the case 2 so as to be freely rotatable. Is rotated by an arbitrary means (method) so that the tip of the guide inclined plate 20 rotates about the horizontal axis 21.
In this case, when one of the left and right side plates 9 of the case 2 is formed of a transparent member, the state of the germ particles falling from the primary sorting dropping port 10 can be visually recognized, and the inclination angle adjustment of the guide inclined plate 20 and the air volume adjustment described later are performed. This is preferable because it is easy to operate.

Thus, the soot that does not fall into the primary sorting and dropping port 10 is discharged from the soot suction and discharging port 7, but in order to make the soot discharged well, the rear falling plate of the soot suction and discharging port 7 and the primary sorting and dropping port 10. 13 is provided with an inclined plate 25, and suction means K is connected to the heel suction / discharge port 7.
The configuration of the suction means K is arbitrary, but one end of the suction transport cylinder 26 is connected to the soot suction discharge port 7, and the suction port 28 of the blower 27 is connected to the middle part of the suction transport cylinder 26 to perform suction. A cyclone 29 is connected to the other end of the transfer cylinder 26 and the cyclone 29 separates the conveying wind and the soot. Reference numeral 30 denotes a suction pressure control valve.

  Therefore, the germ separation and recovery apparatus 1 primarily sorts the particles of the powdered wrinkles, the sized particles, the germ particles, and the like with the inclination of the guide inclined plate 20 and the suction air from the wrinkle suction / discharge port 7, and will be described later. The sorting device 31 is configured to sort the sized and germ particles from the granules.

Thus, the secondary sorting device 31 is provided with a sized sorting body 33 formed by a mesh body having a mesh size smaller than the sized grain, below the discharge port 32 below the primary guide rod 14, and sized sorting. The body 33 sorts and collects the sized particles, finds the sizing leakage in the rice milling process, and then provides and configures a secondary wind sorting section 34 that sorts the germ and small rice.
The secondary wind sorting unit 34 provides a germ sorting body 35 formed by a mesh body having a mesh size smaller than that of germ and small rice at a predetermined interval below the sized sorting sort 33, and ends the germ sorting body 35. (Lower end) Below the secondary sorting air path S of the air volume in which the small rice and the germ fall by their own weight, the secondary sorting air path S is configured to further sort the specific gravity of the small rice and the germ.

  The secondary sorting air path S is configured by providing a blower port 36 below the terminal end (lower end) of the germ sorting body 35, and a blower hose 37 of a blower (not shown) is connected to the blower port 36. A secondary sorting drop port 38 is provided below the secondary sorting air passage S. The secondary sorting drop port 38 is formed in the upper part of the secondary guide rod 39, and the blower hose 37 is attached to the upper part of the secondary guide rod 39 or the lower surface of the germ sorter 35.

In the secondary sorting air passage S, the sorting wind is applied from the blower opening 36 to the germ and the small rice that fall from the germ sorting body 35 to the secondary sorting dropping port 38, and the small specific rice is dropped to the near side, and the germ having a light specific gravity is dropped. To the second order by skipping.
Therefore, if the one end of the sized particle sorting body 33 and the embryo sorting body 35 is inclined at a high end and the other end is inclined low, the sized particle sorting body 33 and the embryo sorting body 35 can be selected during the flow, which is suitable for continuous operation. is there.

In addition, if the sized sorting body 33 and the germ sorting body 35 are always finely vibrated by the vibration motor 40 or the like, the fall of the germ and the cocoon from the sized sorting body 33 and the embryo sorting body 35 becomes good, Is preferred.
The shape of the secondary guide rod 39 is arbitrary, but a small rice drop channel 41 and a germ drop channel 42 are formed in the secondary guide rod 39, and the small rice recovery channel 41 is disposed below the small rice drop channel 41. A chute 43 is provided, and a germ collection chute 44 is provided below the germ drop channel 42.
Further, the secondary guide rod 39 is provided with a partition plate 45 for partitioning each flow path so that the small rice is not mixed with the germ separated at the secondary sorting drop opening 38, and the small rice drop flow path 41 and the germ fall flow path 42. If it is provided in between, the sorting accuracy is further improved, which is preferable.

Therefore, in order to provide the primary sorting device 5 in the suction sorting air passage F, in the embodiment, the case 2 is configured to be a substantially sealed space, and the case 2 has a predetermined position for adjusting the pressure in the case. A plurality of in-case pressure control valves 46 are provided at appropriate positions.
Further, since the secondary sorting device 31 sorts and separates the small rice and the germ by blowing a slight breeze from the secondary sorting air passage S of the secondary wind sorting section 34, it is not necessarily installed in the case 2. It is not necessary to do this, but it is preferable to install it in a case in order to prevent contamination.
Reference numeral 51 denotes a sizing collection chute facing the terminal end of the sizing selector 33.

(Operation of Example)
The rice milling device is driven to whiten the brown rice, separate the white rice from the rice bran, convey the rice cake discharged from the rice milling device, and supply it from the rice bran conveyance supply cylinder 3 into the case 2 of the germ separation and recovery device 1.
On one side of the case 2, a heel supply port 6 for supplying the heel of the heel conveyance supply cylinder 3 is formed, and on the other side of the case 2, a heel suction discharge port 7 for sucking the inside of the case 2 is formed. The powdered soot passes between the mouth 6 and the soot suction discharge port 7, but the germ particles of the granules form a suction sorting air passage F having an air volume that falls by its own weight. The primary sorting device 5 for sorting and separating the soot is provided, so that the soot that is sucked and supplied from the soot supply port 6 is blown off by the suction sorting wind and passes through the primary sorting and dropping port 10 and remains as it is. After being discharged from the suction discharge port 7, the powdered cocoons pass through the suction conveyance cylinder 26 and are separated from the conveying air by the cyclone 29 and collected. The body naturally falls by its own weight into the primary sorting and dropping port 10 of the primary sorting device 5.

Therefore, the primary sorting device 5 separates the wrinkles that are powder from the sized and germ particles that are granulated.
Further, the suction sorting air path F is provided with a guide inclined plate 20 for guiding the object to be processed supplied from the straw supply port 6, and the guide inclined plate 20 is configured to be adjustable in inclination angle. Can be adjusted into the primary sorting dropping port 10 and the inclination angle of the guide inclined plate 20 can be adjusted so that the cocoon can be sucked from the sputum suction / discharge port 7, thereby further improving the efficiency of sorting the germ particles.

That is, the sized granules mainly fall on the side of the primary sorting drop 10 on the side of the straw supply port 6 and the germ particles fall mainly on the side of the primary sorting drop 10 on the side of the straw suction outlet 7. When the inclination angle of the guide inclined plate 20 is adjusted based on the drop of the grains, the efficiency of selecting the germ grains is further improved.
In this case, the case 2 is provided with a plurality of in-case pressure control valves 46 at appropriate locations, so that the amount of air in the suction sorting air passage F, the wind force, and the like are controlled by the in-case pressure control valve 46 and the suction pressure control valve 30. Since it can be adjusted, it is adjusted to the optimum sorting state in combination with the inclination angle adjustment of the guide inclined plate 20.

Thus, the sized particles out of the particles separated from the powder by the primary sorting device 5 flow down to the side of the primary sorting dropping port 10 on the side of the soot supply port 6, and the side of the primary sorting dropping port 10 on the side of the soot suction discharge port 7. In the middle primary sorting drop 10, small rice / crushed rice flows down, but some of the small sized rice and broken rice are mixed in the falling sized and germinated grains.
Therefore, the germ particles are selected from the particles by the secondary selection device 31.
Since the secondary sorting device 31 is provided with a sized sorting body 33 having a predetermined length below the discharge port 32 of the primary sorting device 5, the sized particles, germ grains, small rice, etc. supplied from the discharge port 32. Of these grains, small rice and germ grains are dropped from the sized sorter 33, and the sized particles are dropped from the sized sorter 33 without being dropped from the sized sorter 33, and separated and collected. Recover to 51.

  In the milling process, milled white rice (sized rice) and rice bran are originally collected separately, so even if the granulated particles are mixed in the rice bran due to partial damage of the rice milling machine, etc. In the present application, the sized particles collected in the candy can be easily collected by the sized particle sorting body 33. Therefore, the sized particle collection receptacle 51 is inspected every predetermined time (period). Then, it can be found that the sized particles are mixed in the rice bran due to a malfunction of the rice mill and the rice milling process can be immediately maintained.

In this case, since the sized particle sorter 33 is formed of a mesh having a mesh size smaller than the sized particle, the small rice and the germ in the granule are dropped, but the sized particle flows down on the sized particle sorter 33. Therefore, continuous work is possible and the work efficiency is improved.
Thus, when the germ and the small rice fall from the sized sorting body 33 onto the embryo sorting body 35 and flow down on the inclined germ sorting body 35, the wrinkles adhering to the germ and the small rice are germ sorting. The germ and small rice that fall from the body 35 and do not fall from the germ sorter 35 fall from the lower end of the germ sorter 35 to the secondary sort drop port 38.

Since the secondary wind selection unit 34 is provided below the lower end of the germ sorting body 35, the germ and the small rice dropped from the sized sorting body 33 are subjected to specific gravity sorting by the secondary wind sorting unit 34, and the germ particles are separated. Since the mixed small rice is removed by the secondary wind selection unit 34, the selection accuracy of germ grains can be further improved.
In this case, the secondary wind sorting unit 34 provides a germ sorting body germ sorting body 35 formed by a mesh body having a mesh size smaller than that of germ and small rice at a predetermined interval below the granulated sorting body 33. Since the secondary sorting drop port 38 is formed below the lower end of the sorting body 35 and the air blowing port 36 for blowing air toward the secondary sorting drop port 38 is provided, the secondary sorting drop port 38 Among the falling germ and small rice, the small rice with the higher specific gravity falls to the front, and the lighter specific germ is blown away and subjected to secondary selection.

Therefore, even small rice and germs, which are difficult to sort by particle size, are sorted by specific gravity sorting by wind separation, so the sorting accuracy is improved and continuous operation is possible without clogging, improving work efficiency. Let
As described above, since the primary sorting device 5 and the secondary sorting device 31 perform wind selection in two stages, even small rice and germ that are difficult to sort by particle size can be sorted with high accuracy.

  Thus, the secondary sorting drop port 38 is formed on the upper part of the secondary guide rod 39 for guiding the germ and the small rice falling from the secondary sort drop port 38, and the secondary guide rod 39 has a small rice drop channel 41 and A small rice recovery chute 43 is provided below the small rice drop flow channel 41, and an embryo recovery chute 44 is provided below the germ drop flow channel 42. It is recovered from the path 41 through the small rice recovery chute 43 and the germ is recovered from the germ drop channel 42 through the germ recovery chute 44.

  In this case, in the secondary guide rod 39, the small rice drops in the small rice drop channel 41 on the side close to the lower end of the embryo sorter 35, and the germ particles in the germ fall channel 42 on the far side of the lower end of the embryo sorter 35. Therefore, if the partition plate 45 is provided between the small rice drop channel 41 and the germ drop channel 42 of the secondary guide rod 39, the sorting accuracy is further improved.

In addition, it is preferable that the sized sorting body 33 and the germ sorting body 35 are finely vibrated during sorting by the vibration motor 40 and the like, because the fall of the germ from the sized sorting body 33 becomes good.
Moreover, the partition plate 18 which divides each flow path is provided between the sized particle fall flow path 15 and the small rice-crushed rice fall flow path 17 and the small rice-crushed rice so that the germ separated at the primary sorting drop opening 10 does not mix with others. It is preferable that the secondary sorting device 31 is provided between the drop channel 17 and the germ drop channel 16 and the secondary sorting device 31 is provided below each discharge port so that the sorting accuracy is improved.
In this case, in the embodiment, three secondary sorting devices 31 having the same configuration are provided, but the sized sorter 33 may be partially omitted.
