Description

[0001]
BACKGROUND OF THE INVENTION
The present invention removes grains of grains such as brown rice, white rice, wheat, buckwheat, etc. (those separated from grains among germs, straw layers and starch layers, or fine powder mixed with seed coats, etc.) by a dry structure. The present invention relates to a grain processing apparatus such as a rice mill for home use.
[0002]
[Prior art]
By rotating the stirring tool in the separation basket accommodated in the treatment container, the rice cake separated from the brown rice in the separation basket is passed through a number of separation holes formed in the separation basket and separated from the treatment container. In the rice milling machine that discharges into the gap between the container and the container, as shown in Japanese Patent Application Laid-Open No. 11-333306, a box-shaped paddy container is provided outside the container in communication with the bottom of the container, and the processing container There is known a rice milling machine that is arranged between the bottom wall of the separation basket and the bottom wall of the separation basket and is rotated with a stirring tool so that the rice cake in the processing container can be collected and discharged to the storage container as the fan rotates. ing.
[0003]
Thus, the rice bran storage container of the rice mill which can forcibly discharge the rice bran has a substantially closed and sealed structure, and communicates with the inside of the processing vessel through a single rice cake discharge passage. Therefore, even if the soot in the processing container is subjected to a discharging action through the soot discharge passage to the soot storage container due to centrifugal force and wind pressure accompanying the rotation of the fan, it simply passes through the soot discharge passage and passes through the soot storage container. It is difficult to generate an airflow that tends to return from the culvert reservoir to the processing container. For this reason, the soot in the processing container may not be discharged into the soaking container. In particular, if the amount of milled rice is large and the load applied to the stirrer increases, the rotation of the stirrer and fan decreases and the discharge action also decreases. In addition, the amount of soot discharged from the separation basket into the processing container increases. For this reason, it becomes easy to cause a discharge failure to the culvert container.
[0004]
In order to improve this point, it was also considered to increase the fan's blowing power by enlarging the fan. However, in this case, the soot that flows in a strong air current flows into the soot discharge passage and the soot storage container. It is easy to leak to the outside through a minute gap of the part that is fitted with each other, and when a small amount of rice is milled, a strong air current soars the rice in the separation basket more than necessary, and it is easy to cause cracking and chipping of the rice Become. Therefore, this measure is not practically preferable.
[0005]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to obtain a grain processing apparatus capable of improving the discharging performance of the koji separated in the processing container into the culm storage container.
[0006]
[Means for Solving the Problems]
According to the present invention, by rotating a stirring tool in a separation basket accommodated in a processing container, the straw separated from the grains in the separation basket is passed through a number of separation holes formed in the separation basket. It is discharged into the gap between the processing container and the separation basket, and the discharged soot is disposed between the bottom wall of the processing container and the bottom wall of the separation basket, and the rotation of the fan that rotates together with the stirring tool, A grain processing apparatus that communicates with a processing container and discharges it to a storage container provided outside the container is assumed.
[0007]
  And in order to solve the said subject, the invention which concerns on Claim 1 WHEREIN: The interposition ring which has the spear exit which connects the said processing container and the said sump reservoir | retainer is installed between the said processing container and the said cover body. Arranged to be detachable,Dredging exitA soot discharge passage provided on the upstream side in the rotational direction of the air flow formed in the processing container with the rotation of the fan with respect to the soot storage container, and communicating the processing container and the soot storage container; and An airflow return passage that is provided independently of the soot discharge passage on the downstream side in the rotational direction of the airflow with respect to the soot storage container and that communicates the processing container and the soot storage container, and a partition wall that partitions these passages It is characterized by providing.
[0008]
  In this invention and each of the following inventions, the processing container provided in the apparatus main body may be provided integrally with the apparatus main body, or is separate from the apparatus main body and is detachable from the apparatus main body.It may be attached. In the present invention and each of the following inventions,Even if it can be attached to and detached from the processing container, it may not be removed, for example, it may be provided integrally. However, the former case is excellent in that it can be easily handled, such as cleaning up the accumulated ridges. In the present invention and each of the following inventions, the lid body may or may not have a vent hole, and the stirring tool only needs to be able to stir the grains in the separation basket. The blade described in the form is not necessarily required.
[0009]
In the first aspect of the invention, when the fan is rotated together with the stirring tool, the soot discharged from the separation basket into the processing container is conveyed by the centrifugal force and the wind pressure accompanying the rotation of the fan, and the processing container It can be discharged into the outside tub container. In this case, the airflow generated by the fan and transporting the soot while rotating along the inner peripheral surface of the processing container passes through the soot discharge passage located upstream in the rotational direction of the airflow with respect to the soot storage container. Then, it flows into the soot storage container, changes the flow direction in the container, and returns to the processing container through the air flow return passage located downstream in the rotational direction of the air flow. By separating the inlet and outlet of the soot conveying airflow from the soot storage container in this way, the soot transporting airflow in the processing container can be circulated through the inside of the soot storage container. As the soot-conveying air flow containing soot changes direction within the soot storage container, soot on the air flow is separated and the soot is stored in the soot storage container.
[0012]
  Furthermore, the invention of claim 1An intervening ring having a soot outlet connecting the processing container and the soot storage container is detachably disposed between the processing container and the lid, and the soot discharge passage and the air flow return are disposed in the soot outlet. Partitions that form passages and partition these passagesProvided.
[0013]
  Therefore, the invention of claim 1In this case, after the soot conveying air flow generated by the fan at the bottom of the processing container rises while swirling the gap between the inner peripheral surface of the processing container and the outer peripheral surface of the separation container, the processing container It is discharged into the soot storage container through the soot discharge passage of the soot outlet of the interposed ring sandwiched between the lid and the lid. The airflow thus discharged changes the flow direction in the soot storage container, and returns to the processing container through the airflow return passage of the soot outlet. Therefore, it is not necessary to form a soot discharge passage and an air flow return passage in the processing container, and air flow circulation over both the processing container and the soot storage container can be realized.
  In the invention of claim 2, a passage wall portion located on the downstream side in the rotational direction of the airflow among the passage walls of the interstitial ring forming the soot discharge passage is located in the processing container as viewed from above. It has the introduction guide which protrudes.
  In this invention, by the introduction guide arranged so as to prevent the soot conveying airflow that is generated by the fan and flows through the gap between the processing container and the separation basket, the airflow is smoothly introduced into the soot discharge port, Air flow circulation with the above-described soot separation in the soot storage container can be realized.
[0014]
  The invention according to claim 3Claim 1 or 2The saddle outlet according to the invention has both end walls extending substantially parallel to the radial direction of the interposed ring, and protrudes outward in a laterally elongated shape extending in the circumferential direction of the interposed ring. The opening width of the outlet of the soot discharge passage is made larger than the opening width of the inlet of the airflow return passage.
[0015]
In the present invention, when the air flow including soot passes through the soot discharge passage, a vortex is easily formed on the inner surface side of one end wall facing this soot discharge passage. A part of the cocoon is attached and grows. However, since the opening width of the exit facing the soot storage container of the soot discharge passage is formed wide in advance, even if this opening width narrows with the adhesion, the soot exit has a limited size. It is possible to suppress the narrowing of the opening width of the inlet facing the culvert reservoir in the airflow return passage that is back-to-back with the discharge passage. Accordingly, it is possible to prevent the actual flow cross-sectional area of the soot discharge passage from becoming smaller than the flow cross-sectional area of the air flow return passage, thereby reducing the air flow circulation over both the processing container and the soot storage container.
[0016]

First, the fan 71 is accommodated in the processing container 21 placed on the apparatus body 1 or detached from the apparatus body 1 through the opening at the upper end thereof, and the fan 71 is accommodated in the drive shaft portion 27 a of the rotating shaft 27. After fitting and mounting, the interposing ring 81 with the seal ring 82 is fitted in an appropriate posture so that the installation step portion 83 is placed on the upper end opening edge 21c of the processing vessel 21, Place on the processing vessel 21. Next, the separation car 31 is accommodated in the processing container 21 until the overhanging flange 34 of the car 31 is hooked on the interposed ring 81 from above. As the separation car 31 is accommodated, the drive shaft portion 27 a of the rotating shaft 27 is inserted into the central cylindrical body 33.
[0048]
Thus, in a state where the fan 71 and the separation basket 31 are accommodated in the processing container 21, the car bottom wall 32b of the car main body 32 is disposed away from the inner surface of the bottom wall 21b of the processing container 21, as shown in FIG. A bottom gap BG is formed between the bottom walls 32b and 21b, and the car peripheral wall 32a of the car body 32 is disposed away from the inner peripheral surface of the peripheral wall 21a of the processing vessel 21, and between the side walls 32a and 21a. Is formed with a circumferential gap SG having a ring shape in plan view. The lower end of the circumferential gap SG is communicated with the bottom gap BG. The fan 71 is disposed in the bottom gap BG communicating with the inside of the car body 32 through a number of separation holes (not shown) formed in the car bottom wall 32b.
[0049]
The upper end of the circumferential space SG communicated into the car body 32 through a number of separation holes (not shown) opened in the car peripheral wall 32a is substantially closed by an inward flange 84 approaching the car peripheral wall 32a. The lower part of the rib 93 of the interposing ring 81 is inserted and arranged above the gap SG. In this arrangement state, the rib base 93a of the rib 93 is brought close to the upper outer peripheral surface of the car peripheral wall 32a, and the upper portion 93bu of the introduction guide 93b of the rib 93 is viewed from above as shown in FIG. It protrudes into SG. In other words, the upper part 93bu is arranged so as to prevent the flow of the airflow that tries to rotate in the circumferential direction along the upper part of the peripheral gap SG. In addition, in the arrangement state, the peripheral gap SG is communicated with the inlet of the soot discharge passage 91 of the soot outlet 86 and the outlet of the air flow return passage 92 inside the interposing ring 81, and these passages 91, The air flow entering and exiting the 92 is prevented from being mixed by the upper portion 93bu.
[0050]
Next, the stirring tool 41 is accommodated in the separation car 31 through its upper end opening, and the central cylinder part 42 a is fitted and attached to the drive shaft part 27 a of the rotary shaft 27. Thereafter, a desired amount of brown rice is accommodated in the separation basket 31. Further, until this state is reached, or after brown rice is stored in the separation basket 31, the container body 62 of the paddle storage container 61 is attached to the outside of the processing container 21 by fitting with the paddle outlet 86. The main body 62 is covered with a lid 63.
[0051]
Next, the lid 51 is attached on the intervening ring 81 using the handle 23 and the spout 24 of the processing container 21 by the mounting procedure described above. Thereby, the upper end opening of the separation basket 31 is closed, and the interposed ring 81 with the seal ring 82 is sandwiched between the lid 51 and the upper end opening edge 21c of the processing vessel 21, and this cage The overhanging flange 34 of 31 is also sandwiched between the interposed ring 81 and the pressing rib 56 of the lid 51. By such a lid, the spout hook portion 53 of the lid 51 is hooked on the spout 24 of the processing container 21 covered with the projection (not shown) of the overhanging flange 34. The ring 81 is prevented from rotating in the circumferential direction, and the seal ring 82 seals between the processing vessel 21 and the interposition ring 81 and between the ring 81 and the lid 51.
[0052]
The attachment 20 assembled in the above procedure is attached to the apparatus main body 1. In this case, even when the processing container 21 is previously placed on the processing container placing portion 3 of the apparatus main body 1 or when the attachment 20 is assembled in a state of being detached from the apparatus main body 1, the attachment is initially performed. 20, the reservoir container 61 is located on the opposite side of the top cover 1c of the apparatus main body 1, and the switch operation convex part 54 of the lid 51 is located on the front side of the switch protrusion 17 of the apparatus main body 1. After mounting on the processing container mounting part 3 in the posture, the attachment 20 is attached to the apparatus main body 1 by rotating the entire attachment 20 in the direction of arrow C in FIG. In this attached state, the driving side coupling 9 and the driven side coupling 28 are meshed with each other to be connected to a state in which power can be transmitted from the apparatus main body 1 side to the stirrer 41, and within the recess 3a. The convex portion projecting from the peripheral surface and the concave portion provided on the outer peripheral surface of the processing vessel base 22 are caught and the processing vessel 21 is prevented from coming out above the processing vessel mounting portion 3. Further, the switch operation convex portion 54 of the lid 51 enters the opening 17a of the switch convex portion 17, and a safety switch (not shown) is held in the ON state.
[0053]
Then, after the above set is completed, by setting the time of the milled rice switch, that is, the timer switch 14, according to the amount of brown rice put into the separation basket 31, the separation of rice bran by the following dry structure, In other words, rice milling (graining) or rice polishing (graining) is carried out.
[0054]
That is, the drive mechanism 10 in the apparatus main body 1 is operated, and the rotation of the output shaft 8 is transmitted to the rotation shaft 27 through the couplings 9 and 28, and the stirring tool 41 is moved together with the shaft 27 in the separation basket 31. It is rotated (the direction of rotation is indicated by a dotted arrow D in FIG. 3). Therefore, the brown rice in the separation basket 31 is pushed toward the car peripheral wall 32a while receiving the rotational force by the pair of blades 44 of the stirring tool 41. Thereby, the brown rice moves toward the upper side of the inner peripheral surface of the car peripheral wall 32a while rotating while being pressed against the inner peripheral surface of the car peripheral wall 32a of the separated car 31 by the action of centrifugal force, Since it is moved in the direction of the car bottom wall 32b on the center side of the separation basket 31 by gravity, the rice in the separation basket 31 is swirled evenly while convection in the vertical direction.
[0055]
By the rubbing of the brown rice accompanying such stirring, and the rubbing of the brown rice with the separation basket 31 and the stirring tool 41, the polished rice from which the straw layer of the brown rice is first removed is performed, and then the polished rice ( The rice bran (ken rice) is performed on white rice. At the same time, the generated basket passes through the separation holes of the car peripheral wall 32a and the car bottom wall 32b and is discharged to the peripheral gap SG and the bottom gap BG. Inside is the rice from which the rice cake has been removed.
[0056]
At the time of the above rice milling, the fan 71 connected to the rotating shaft 27 is rotated together with the rotating shaft 27 in the bottom gap BG, so that the fan 71 blows air by its blades 74. By this blowing, the upper side of the fan 71 becomes the suction side, and the outer peripheral side of the fan 71 becomes the exhaust side.
[0057]
Therefore, outside air is sucked from the air holes 55 of the lid body 51, passes through the brown rice layer (cereal layer) in the separation basket 31, reaches the bottom gap BG through the separation hole of the basket bottom wall 32b, After passing through the fan 71 from the bottom gap BG, it rises while turning the peripheral gap SG. On the side of the intervening ring 81, the air flow can be changed upward by the introduction guide 93b of the ring 81, and the inclined surface 90a of the partition wall 90 of the soot outlet 86 that is flush with the upper part 93bu and the upper part 93bu. Is introduced into the soot discharge passage 91. Then, the airflow flows through the soot discharge passage 91 and reaches the inside of the soot storage container 61, hits the inner surface of the container 61, changes the flow direction toward the processing container 21, and then adjoins the passage 91. It returns to the lower side of the inward flange 84 of the interposition ring 81 through the matching air flow return passage 92. The airflow thus returned flows downward along the lower surface of the tapered portion 84a of the inward flange 84 connected to the outlet of the passage 92, is returned to the peripheral space SG, and the car facing this space SG. It returns to the separation basket 31 through the separation hole at the top of the peripheral wall 32a. The swirling airflow and the airflow passing through the eaves outlet 86 are indicated by solid lines and two-dot chain arrows in FIGS. 3 and 4.
[0058]
For this reason, the soot discharged | emitted from the separation hole of the car bottom wall 32b and the car surrounding wall 32a can be carried on the above-mentioned airflow from the side discharged | emitted by the said space | gap BG and SG. The soot thus transported is separated from the airflow as the airflow strikes the inner surface of the soot storage container 61 except for the connection portion with the soot outlet 86 and is turned as described above. Is stored in the lower part of the container 61. By automatically carrying out such rice cake, the rice cake separated from the brown rice is not collected in the bottom gap BG, and this rice cake can be discharged and collected in the rice cake container 61 having a low temperature condition outside the processing vessel 21.
[0059]
In the soot treatment described above, the soot discharge passage 91 and the air flow return passage 92 are separated via the partition wall 90 as described above. In other words, the entrance and exit of the soot conveying air flow to the soot storage container 61 are provided. By being divided, the airflow that flows from the processing container 21 side into the soot storage container 61 does not hinder the flow of the airflow that tries to return from the soot storage container 61 to the processing container 21 side. Therefore, the soot conveying airflow generated in the processing container 21 can be smoothly circulated through the inside of the soot storage container 61, and the soot that is riding on the soot conveying airflow can be easily and reliably removed. It can be carried into the reservoir 61 and separated and stored there.
[0060]
The partition wall 90 that divides the soot discharge passage 91 is provided with an upper part 93bu of the continuous introduction guide 93b. This upper part 93bu is generated by the fan 71 and is formed between the inner surface of the processing vessel 21 and the separation basket 31. Since it is arranged so as to prevent the soot conveying airflow flowing while turning around the peripheral space SG, the airflow can be smoothly introduced into the soot discharge passage 91 by the upper portion 93bu of this introduction guide 93b. In addition, in the present embodiment, the air flow can be prevented from being blown into the air flow return passage 92 adjacent to the soot discharge passage 91 by the upper portion 93bu. Therefore, the air circulation with the soot separation described above in the soot storage container 61 can be realized smoothly and reliably.
[0061]
In addition, in the present embodiment, since the upper portion 93bu is inclined, the airflow is less disturbed, and the airflow can be introduced into the culvert container 61 more smoothly. In addition, since the airflow swirling in the peripheral space SB is guided to the rib 93 having the upper portion 93bu and introduced into the soot discharge passage 91 as described above, compared to the case where there is no such rib 93, Of course, the air stream containing soot can be introduced more easily.
[0062]
Further, the rod outlet 86 has both end walls 86a and 86b extending substantially parallel to the radial direction of the interposed ring 81, and protrudes outward in a horizontally long shape extending in the circumferential direction of the interposed ring 81. Therefore, the attachment / detachment of the soot storage container 61 to the soot outlet 86 can be easily performed by inserting / removing from the outside in the radial direction of the processing heat 21. On the other hand, when the air flow including soot passes through the soot discharge passage 91, a vortex is formed on the inner surface side of the end wall 86a facing this soot discharge passage 91. Therefore, a part of the soot contained in the airflow adheres and grows on the inner surface of the end wall 86a. In addition, since the inclined surface 90a of the partition wall 90 facing the soot discharge passage 91 is along the flow direction of the airflow passing through the soot discharge passage 91 as described above, the soot adhesion to the soot is almost negligible. Few.
[0063]
However, since the opening width A of the outlet facing the soot storage container 61 of the soot outlet 86 of the soot outlet 86 is formed larger than the opening width B of the inlet facing the soot storage container 61 of the air flow return path 92, Even if the substantial opening width of the outlet of the soot discharge passage 91 becomes narrower due to the adhesion, it can be suppressed that the opening width is narrower than the opening width B of the inlet of the air flow return passage 92. As a result, the actual cross-sectional area of the soot discharge passage 91 is smaller than the cross-sectional area of the air flow return passage 92, thereby preventing the air flow circulation across both the processing vessel 21 and the soot reservoir 61 from being lowered. it can. Therefore, the air flow circulation with the above-described soot separation in the soot storage container 61 can be reliably maintained. The partition wall 90 facing the soot discharge passage 91 as the inclined surface 90 a is effective for making a difference in the sizes of the opening widths A and B at the soot outlet 86.
[0064]
Since the rice cake separated from the rice is discharged to the rice cake storage container 61 outside the processing container 21 by the circulating air flow as described above, it is substantially the case that the rice cake remains in the processing container 21 even when the amount of polished rice is large. Can be eliminated. Therefore, as in the case where the soot accumulates in the inner bottom portion of the processing container 21, the soot does not stick to the inner bottom portion of the processing container 21 with the temperature rise of the soot and remains in the processing container 21 after use. Can be easily cleaned. In addition, since the soot storage container 61 is outside the processing container 21 and exposed to the outside air, the temperature of the soot discharged inside the container does not increase, and the soot does not become sticky. By removing from the container 21, the soot stored in the soot storage container 62 can be taken out easily. Therefore, this rice mill is easy to use because it is easy to process rice bran as described above.
[0065]
Since the soot can be automatically discharged into the container 61 as described above, the peripheral space SB is narrowed, that is, even if the processing container 21 has a small diameter and the peripheral wall 21a approaches the car peripheral wall 32a, it is discharged from the separation basket 31. The clogged clogging does not clog the peripheral space SB and clog the separation hole of the separation basket 31. Therefore, the processing vessel 21 can be made small.
[0066]
The air flow circulation between the processing container 21 and the inside of the paddy container 61 described above is performed in the same manner even if the amount of polished rice is large and the rotation of the fan 71 is decreased. Therefore, despite the increase in the amount of soot, it is possible to prevent defective discharge into the soot storage container 61. Accordingly, it is not necessary to increase the fan 71 to increase the blowing power in order to prevent the defective discharge of the bag, so that not only does the size increase due to the height of the attachment 20 increase, Excessive wind pressure due to the improvement of the blowing force is applied to the fitting portion between the soot outlet 86 and the soot storage container 61 and the fitting portion between the container main body 62 and the lid 63, and the soot is brought outside through these fitting portions. The risk of leakage can also be prevented.
[0067]
Further, in the above rice milling operation, since the outside air is introduced through the lid 51 as described above, not only the brown rice that has been stirred and generating frictional heat, but also the parts that are in contact with the air flow (brate 44, separation basket). 31 etc.) can be actively cooled. Therefore, it is possible to effectively suppress the temperature rise of the brown rice being stirred and the separated rice bran. Therefore, the dryness of the rice accompanying the above-mentioned polished rice can be reduced, and it is effective in reducing the crack of the rice at the time of cooking rice and improving the taste.
[0068]
In addition, the rice mill of this embodiment can perform the rice washing (grain washing) after the said rice polishing. In this washing, the white rice in the separation basket 31 removed from the processing container 21 is lightly wetted with water and drained, and then the separation basket 31 is set in the processing container 21 again, and the assembly procedure described above is performed. This is done by assembling the attachment 20 and setting it in the apparatus body 1.
[0069]
In this rice washing operation, the timer switch 14 is not used, and the drive motor 4 is intermittently operated by momentarily pushing the rice washing switch 15 several times according to the amount of white rice in the separation basket 31. Thereby, the stirrer 41 stirs the white rice without substantially excessively shaving, and the rice washing is performed. After this, according to the above-described removal procedure, the separated basket 31 is taken out together with the white rice, and with the separated basket 31 immersed in water, the stirring tool 41 is removed from the separated basket 31, and the white rice is rinsed lightly. Washing the rice is completed by washing. In this rice washing operation, draining is not sufficient, and it is conceivable that excessive water drops from the separation basket 31 into the processing container 21 while being set in the processing container 21. However, since the soot outlet 86 is provided on the upper end opening edge 21 c side without the bottom of the processing vessel 21, there is no possibility that the excess water flows out into the soot reservoir 61 through the soot outlet 86.
[0070]
According to the rice treatment as described above, the rice bran is separated from the rice in the polished rice or the polished rice, so even when washing the rice manually without using the rice washing operation using the rice mill, Even when the rice washing operation is performed using the rice mill as described above, since the amount of rice bran contained in the rinsing water is extremely small, the rice sucks the water containing the rice bran dissolved in the rice washing, and the rice becomes odorous. This can be suppressed. Therefore, rice can be cooked deliciously by the rice cooking after this.
[0071]
Further, as described above, the interstitial ring 81 having the soot outlet 86 is disposed between the processing vessel 21 and the lid 51 and used, so that the soot discharge passage 91 and the air flow return passage are provided in the processing vessel 21. 92 need not be provided. Therefore, for example, even if the attachment 20 having the above-described configuration is attached to a new food processor having a switch that can switch the number of revolutions of the existing motor or the drive motor between cooking and rice milling, the above-described rice milling and milling can be performed. In this case, the versatility of the food processor can be improved, and the processing vessel 21 can be shared for the rice milling and the food processor.
[0072]
In the rice mill, a bag made of vinyl, paper, or the like prepared separately in place of the culvert container 61 can be attached to the culm outlet 86 to receive the culm discharged as described above. In this case, the bag can be easily handled, such as simply discarding the bag.
[0073]
In addition, this invention is not restrict | limited to the said embodiment, It is possible to implement the refined grain or grain which performs the process similar to polished rice with respect to grains other than rice, and the rice washing switch 15 May be omitted.
[0074]

  According to the first aspect of the present invention, the soot-conveying airflow in the processing container is passed through the processing container and the soot-storing container on the outside of the processing container through the mutually independent soot discharge passage and the air flow return path. So that it can be circulated smoothly and without any measures to increase the possibility that the soot leaks to the outside, such as increasing the blowing power of the fan, and so on, the soot separated into the processing container can be discharged into the soot storage container. Improve performanceit can. In addition, since the intervening ring having the soot outlet in which the soot discharge passage and the air flow return passage are formed is detachably disposed between the processing container and the lid, the soot discharge passage and the air flow return passage are formed in the processing container. It is possible to solve the problems of the present invention by realizing air flow circulation with separation of soot in the soot storage container as well as in both the processing container and the soot storage container.A grain processing apparatus can be provided.
