Description

  The present invention relates to a polishing apparatus for further removing wrinkles from white rice grains.

  Conventionally, as this kind of research machine, as disclosed in JP-A-59-47471, JP-A-55-102944, JP-A-59-92032, JP-A-8-10372 In addition, there has been known one provided with a removal cylinder (perforated cylinder) having a number of falling holes, and a screw roll that is rotationally driven in the polishing cylinder and has a spiral brush planted on a roll shaft. The white rice grains put into the dehuller are scraped off by the rotation of the spiral brush, and the rice cakes are dropped and discharged through the hole, and the polished rice grains are transferred to the outlet side and discharged. .

  This spiral brush has a polishing function for scraping rice cake from white rice and a screw conveyor function for transferring the white rice to the outlet side. In order to exhibit the screw conveyor function, stiff brush bristles are required, but the sharp brush bristles rub against the surface of the white rice grains by point contact, so the polishing function is not improved. When soft brush bristles are used, the screw conveyor function is lowered, and the bristles are bent with a bended tip, so the polishing function is slightly improved.

In order to solve this problem, the present applicant has disclosed a rice mill equipped with a screw roll having both stiff brush bristles and soft bristles according to Japanese Patent Application Laid-Open No. 2004-298801.
JP 59-47471 A Japanese Utility Model Publication No. 55-102944 JP 59-92032 A Japanese Utility Model Publication No. 8-10372 JP 2004-298801 A

  However, even with a brush that has both hard and soft bristle, basically, the tip of the bristle only scratches the surface of the white rice grains by point contact, so it turns out that the polishing performance does not improve as much as the left did.

  Therefore, in view of the above problems, an object of the present invention is to provide a rice polishing apparatus with greatly improved rice polishing performance.

  The invention according to claim 1 is a polishing cylinder having a white rice dropping opening on the upper end side and a polishing rice discharge opening on the lower end side, and a polishing machine which is rotationally driven in the removal cylinder and has a polishing material on the outer peripheral surface. A rice polishing apparatus comprising a rice roll is characterized in that the polishing material is composed of a number of flexible loops.

  A large number of flexible loops bend along the surface of the white rice grains against the white rice grains dropped into the gap between the dehulling cylinder and the rotating polishing rice roll from the white rice dropping mouth, and scrape the rice cake with the loop area. Because of scraping, sharpening performance is greatly improved.

  Here, it is desirable that the loop rows of a large number of flexible loops constituting the polished rice are oriented in the circumferential direction of the polished rice roll. The white rice grains dropped by the rotating polishing rice roll are subjected to a circumferential force, but if the loop row is oriented in the circumferential direction of the polishing rice roll, the white rice grains are more circumferentially aligned. Since the number of rounds of white rice grains increases as it rotates, the number of loops that boil the surface of the white rice grains increases, which greatly improves the polishing performance.

  In addition, it is desirable that a large number of flexible loops constituting the polished rice material have opposite ends whose tips are inclined in the rotating direction of the polished rice roll. The dropped white rice grains are sent in the circumferential direction by the flexible loop of the reverse eye, the number of rounds of the white rice grain increases, and the pressing action against the white rice grain is strengthened by the reverse eye, so the polishing performance Is greatly improved.

  It is desirable that a large number of flexible loops constituting the polished rice material are formed on a cushion layer covering the outer peripheral surface of the core cylinder. Since the portion of the loop that hits the white rice grains is recessed, the range of padding with the loop for the white rice grains is widened, improving the polishing performance.

  Commercially available loop hook-and-loop fasteners are suitable for providing a large number of flexible loops. It is inexpensive and has excellent durability. Moreover, since it is a hook-and-loop fastener, it can be easily equipped on the Kenmai roll in the sticking process.

  According to a sixth aspect of the present invention, there is provided a polishing cylinder having a white rice dropping opening on the upper end side and a polishing rice discharge opening on the lower end side, and a polishing machine which is rotationally driven in the removal cylinder and has a polishing material on the outer peripheral surface. A rice polishing apparatus comprising a rice roll, wherein the rice polishing roll is detachable from the stripping cylinder, a core cylinder, a cushion layer covering an outer peripheral surface of the core cylinder, and the core A pair of elongated holes provided along a generatrix having a positional relationship of about 180 ° with respect to the center of rotation of the cylinder and the cushion layer, an endless loop loop fastener surrounding the cushion layer, and the endless loop Elastic means for pulling and urging a pair of curved margin portions of the surface fastener into the inner space of the core cylinder through the pair of elongated holes, and the polished material is made of a number of flexible loop surface fasteners. It is a sex loop.

  As mentioned above, because it is a large number of flexible loops of loop hook-and-loop fasteners as a polished rice material, a large number of white rice grains dropped into the gap between the dehulling cylinder and the rotating polishing rice roll from the white rice drop mouth Since the flexible loop bends following the surface of the white rice grains and scrapes and scrapes off the straw in the loop area, the polishing performance is greatly improved. If the polishing process is performed for a certain period of time, wrinkles also adhere to the loop surface fastener, and the polishing ability is deteriorated or the loop surface fastener deteriorates. Therefore, it is necessary to replace the loop surface fastener. At the time of this replacement, the pair of curved margin portions are removed from the long holes through the cushion layer by simply pulling out the polishing roll from the removal cylinder and removing the elastic means in the inner space of the core cylinder from the pair of curved margin portions. Since the endless belt-shaped loop surface fastener can be easily removed from the roll, the endless belt-shaped loop surface fastener can be cleaned or cleaned. When installing an endless belt loop fastener that has been cleaned or washed or a new endless belt loop fastener to an abrasive roll, insert the abrasive roll into the endless loop fastener and lengthen the curved margin. By inserting into the inner space through the hole and connecting the pair of curved margin portions with elastic means, an endless belt-like loop surface fastener can be brought into close contact with the cushion layer. The cushion layer also serves to prevent the slippage of the endless loop loop fastener.

  The invention according to claim 7 has a white rice dropping port on the upper end side and a polishing rice discharge port on the lower end side, respectively, and the first polishing material and the lower half peripheral surface are removed on the upper half peripheral surface of the peripheral surfaces. A rice polishing apparatus comprising: a tilting removal cylinder having a hole and a polishing roll having a second polishing material on the outer peripheral surface thereof, which is rotationally driven in the removal cylinder. The first and second polishing materials are characterized by comprising a large number of flexible loops. According to the present invention, in contrast to the invention according to claim 1, the first polishing material is also provided on the upper half peripheral surface of the peripheral surface of the stripping cylinder. It consists of a flexible loop. For this reason, the polishing effect on white rice grains is enhanced.

  It is desirable that the loop rows of the multiple flexible loops constituting the first polished rice material are oriented in the circumferential direction of the upper half circumferential surface. Since the white rice grains are further rotated along the circumferential direction and the number of rounds of the white rice grains is increased, the number of loops for boiling the surface of the white rice grains is increased, so that the polishing performance is greatly improved. Moreover, it is desirable that the multiple flexible loops constituting the first polished rice material have opposite ends whose tips are inclined in the rotating direction of the polished rice roll. The dropped white rice grains are sent in the circumferential direction by the flexible loop of the reverse eye, the number of rounds of the white rice grain increases, and the pressing action against the white rice grain is strengthened by the reverse eye, so the polishing performance Is greatly improved.

  The white rice dropping opening is desirably provided near the boundary between the upper half circumferential surface and the lower half circumferential surface at the upper end surface of the dehuller tube. This is because the white rice grains from the white rice dropping mouth easily enter the gap between the dehuller and the polishing rice roll. Moreover, it is desirable that the polished rice roll rotates in the direction from the upper half circumferential surface to the lower half circumferential surface at the white rice dropping opening. There are no many flexible loops on the lower half of the surface of the dehuller, and gravity acts on the white rice grains from the white rice dropper. It is because it becomes easy to enter.

  The invention according to claim 13 has a white rice dropping port on the upper end side and a polished rice discharge port on the lower end side, respectively, and the first half of the inner circumferential surface is removed on the upper half circumferential surface and the lower half circumferential surface is removed. A rice milling apparatus comprising: a sludge removing cylinder having a steep hole, and a rice polishing roll that is rotationally driven in the removing cylinder and has a second polishing material on the outer peripheral surface, The stripping cylinder is provided along a polished rice sheet in which a loop surface fastener is bonded to a flexible plastic sheet, and both side end generatrix directions of the upper half circumferential surface, for guiding both edges of the polished rice sheet A pair of guide grooves, and the polished rice material is composed of a number of flexible loops of the loop surface fastener.

  After a certain period of polishing, the loop hook-and-loop fastener, which is the first polishing material, will also become wrinkled, reducing the polishing ability or deteriorating the loop hook-and-loop fastener. It becomes. At the time of this replacement, the polished rice sheet can be pulled out from the pair of guide grooves, so that the loop surface fastener on the flexible plastic sheet can be cleaned or washed. When a polished or new polished rice sheet or a new polished rice sheet is attached to the scouring cylinder, the edges of the polished rice sheet are bent into a tunnel shape and the edges are inserted into a pair of guide grooves. The rice sheet is brought into close contact with the upper half circumferential surface of the removal cylinder by its elastic restoring force.

  The invention according to claim 14 uses a loop hook-and-loop fastener having a plurality of flexible loops on the surface as the polishing material in the polishing apparatus provided with the polishing material for removing wrinkles from the white rice grains. It is characterized by comprising. Because it is a large number of flexible loops of loop hook-and-loop fasteners as a polished rice material, a large number of flexible loops bend along the surface of the white rice grains against the white rice grains, and scrape by scraping and scoring the rice cake with the loop area. The sharpening performance is greatly improved.

  Since the polished rice is a large number of flexible loops, it can bend following the surface of the white rice grains, and can be scraped and scraped off with the loop area, which greatly improves the polished rice performance.

  The rice milling machine of this example is a stand-alone type to be installed in the next stage of a rice milling machine (not shown), the rice milling machine main body 1, and the cerealing device 2 erected adjacent to one side of the rear surface thereof, A white rice introduction device 3 for introducing the white rice discharged from the exit mill (not shown) of the rice mill into the lower receiving part 2a of the cerealing device 2;

Here, as shown in FIGS. 1 to 3, the white rice introduction device 3 includes a first pyramid-shaped hopper receiver 3 a that is installed with a lower end portion that can be inserted into the receiving port A of the lower receiving portion 2 a, and FIGS. As shown in FIG. 6, a receiving height changing member 3b provided with a joint pipe B that can be fitted into the receiving port A of the lower receiving portion 2a is provided instead of the first conical hopper receiving 3a. The receiving height changing member 3b includes a second conical hopper receiver C on the upper end side, a support shaft D provided on the back side of the cerealing device 2 on the center line of the circular receiving port A, and the support shaft D. Is connected to the horizontal arm E that can be turned around the turning center, the 45 ° elbow pipe F that is fitted to the hanging portion of the second conical hopper receiver C, and the lower end of the elbow pipe F. The inclined extended pipe G, the inverted 45 ° elbow pipe H connected to the lower end of the inclined extended pipe G, and the joint pipe connected to the lower end of the inverted 45 ° elbow pipe H and rotatable in the receiving port A. B. Horizontal arm E includes a clamping wheel d ₂ for fixing the hanging portion of the second cone-shaped receiving hopper C and consuming wheel d ₁ loosely fitting the support shaft D at one end thereof to the other end. The support shaft D is supported upright by a support fitting I fixed to the cerealing device 2.

Here, when the exit rice bran of the rice mill is at a lower position than the floor surface, as shown in FIGS. 1 and 2, the first pyramid-shaped hopper receptacle is received at the receptacle A of the lower receptacle 2a of the cerealing device 2. 3a can be installed to receive white rice. When the exit mill of the rice milling machine is at a high position with respect to the floor surface, the receiving height changing member 3b is used instead of the first pyramidal hopper receiver 3a. The hanging ring d ₁ is fitted onto the support shaft D, and the joint pipe B is fitted into the receiving port A. Since the hanging ring d ₁ is rotatable with respect to the support shaft D and the joint pipe B is also rotatable within the receiving port A, the second conical hopper receiver C is as shown in FIGS. , About 180 ° rotation with respect to the support shaft D is possible. For this reason, although various types of rice milling machines have different arrangements of outlet culverts, the second cone-shaped hopper receiver C can be swiveled and arranged directly under the outlet culm, and the white rice discharged from the outlet culm It can be introduced to the lower receiving portion 2a through the conical hopper receiver C and the tendency extension pipe G.

  The cerealing device 2 is a bucket conveyance device, and after transferring the white rice introduced into the lower receiving portion 2a to the upper portion of the rice polishing machine main body 1, a third is arranged on the top of the rice polishing machine main body 1 from the discharge portion 2b. Drop into the pyramid-shaped hopper receiver 10 (see FIGS. 7 and 8). In addition, 2c is a motor which drives the cerealing apparatus 2.

  The main body 1 has a triangular roof-shaped flip-up door body (hood) 11 protruding forward at the upper front. This flip-up type door body 11 covers the protruding part from the side frame 13 of the inclined rice polishing part 20, an operation panel 11 a is provided on the upper inclined surface, and a discharge basket is provided below the lower inclined surface. 11b protrudes. When the latch (not shown) is released, the flip-up door body (hood) 11 is flipped upward by the restoring force of the gas spring 11c to open the door. A lid plate 12 that closes the inspection window is screwed to the top surface of the main body 1 of the rice polishing machine.

  7 and 8 show a state where the outer cylinder of the main body 1 is removed. During the polishing operation, the polishing unit 20 is inclined. At the time of maintenance or the like, the polishing unit 20 can change its posture to the horizontal posture shown in FIG. The polished rice portion 20 can be roughly divided into a box-shaped polished rice frame 30 and a polished rice assembly 40 that can be inserted and removed through a lower opening therein. A pair of gripping members 16 and 16 are fixed to the top frame 14 of the main body 1 of the grind machine 1 so as to pass through and support the horizontal support shaft 15. Both end sides are loosely fitted to bearing plates 31 a and 31 a provided on the upper frames 31 and 31 of the polished rice frame 30. For this reason, the polished rice section 20 can turn (tilt) about the horizontal support shaft 15 as a turning center.

  On the other hand, between the lower frame 32 of the polishing rice frame 30 and the beam frame 17 of the polishing machine main body 1, a four-joint double lever link mechanism is configured with a connecting link 18 and a hook link 19. Yes. The polished portion 20 corresponds to the first hook link since it is a pair of turns with respect to the horizontal support shaft 15 as a fixed joint, and the hook link 19 is a pair of turns around the beam frame 17 which is a fixed joint. It corresponds to a 梃 link. One end side of the connecting link 18 turns around the lower frame 32, and the other end side turns around the beam link 17. For this reason, as shown in FIG. 11, the polished portion 20 indicated by the solid line can tilt to the horizontal position indicated by the two-dot chain line through the hanging attitude of the one-dot chain line, and can also tilt in the opposite direction. It has become.

  Here, as a mechanism for maintaining the polished portion 20 in an inclined posture indicated by a solid line and a horizontal posture indicated by a two-dot chain line, a hook that locks the relative movement of both the connecting link 18 and the saddle link 19 is used. A stop mechanism, a notch 19a formed at one end of the saddle link, an engagement pin 18a pushed and urged by a coil spring (not shown) on the connecting link 18, and a side surface of the polished rice frame 30 An unlocking wire W for pulling the engaging pin 18a against the biasing force of the coil spring is provided. The distal end side of the wire W is passed through a guide sleeve S provided on the polished rice frame 30. In addition, a wire bending guide V is provided on the polished rice frame 30 in the vicinity of the pair of joints between the connecting link 18 and the polished rice frame 30.

  In the inclined posture state of the polished rice portion 20 shown by the solid line in FIG. 11, the engaging pin 18a is engaged with the notch 19a, and the relative movement between the connecting link 18 and the flange link 19 is locked. Therefore, the articulated link 18 and the saddle link 19 are supported as a single bar, so that they do not tilt to the dangling line. Here, when the tip end of the wire W is pulled in the direction of the arrow α shown in the figure, the engaging pin 18a is separated from the notch 19a against the urging force of the coil spring, and the connection link 18 and the hook link 19 are integrated. Since it is cancelled | released, the polished rice part 20 naturally tilts to the hanging state of the dashed-dotted line of illustration. In this state, the engaging pin 18a is pushed out by the urging force of the coil spring. When the bottom side of the polished portion 20 is lifted from the state of the one-dot chain line to a horizontal posture, the connecting link 18 and the saddle link 19 overlap, so that the tip of the engaging pin 19a is connected to the curved guide edge 19b near the notch 19a. The articulated link 18 and the saddle link 19 are supported as a single bar, and the polished rice portion 20 is held in a horizontal position of a two-dot chain line. When the wire W is pulled in the direction of the arrow β shown in the figure, the engagement between the notch 19a and the engagement pin 18a is released, and the polished rice portion 20 is tilted to the hanging state of the one-dot chain line. Is pushed further toward the rear side of the main body 1 and the notch 19a and the engaging pin 18a are engaged, and the polished portion 20 is held in the inclined posture shown by the solid line.

  A driven bevel gear 33 of a roll shaft (driven shaft) 33 a protrudes from the back side of the polished rice frame 30. As shown in FIG. 8, the inclined gear 33 meshes with the drive inclined gear 6 fixed to the drive shaft 5 of the rice polishing motor 4 provided in the rice polishing machine body 1 in the inclined posture of the rice polishing apparatus 20. Further, the polished rice frame 30 is hinged to the lower ends of the folding rectangular plates 35 and 35 and the opening rectangular frame 36 for preventing the polished rice assembly 40 from being rotated, and is attached to the upper ends by two knob bolts 37. And an assembly presser 38 to be fastened.

  The polishing rice assembly 40 includes a dehulling cylinder 50 that fits in the polishing hose 30, a polishing rice roll 60 that fits in the dehulling cylinder 50, and an end lid 70 that closes the opening of the dehulling cylinder 50. The dehulling cylinder 50 has a cylindrical body 52 whose lower half is a dehulling net 51, a white rice dropping port 53a for introducing white rice from the third pyramid-shaped hopper receiver 10 into the cylindrical body 52, and a roll shaft 33a. An octagonal end plate 53 having a bearing 53 b and an octagonal opening frame 54 provided around the lower opening of the cylindrical body 52 are provided. The white rice dropping opening 53 a is provided on the outer peripheral side of the end plate 53 in the vicinity of the boundary between the dehiding net 51 of the cylindrical body 52 and the non-hulled portion 51 a of the upper half circumference. A driven bevel gear 33 is fixed to a roll shaft 33 a that protrudes outward from the end plate 53. In the state where the polishing roll 60 is removed from the inside of the removal cylinder 50, the roll shaft 33a is cantilevered by a bearing 53b. On the bearing 53b side of the roll shaft 33a, a pin joint X for rotating and driving the polishing roll 60 in the cylindrical body 52 is fixed through.

  As shown in FIG. 17, the polishing roll 60 has a cylindrical roll body 61, an end cover 62 having a groove joint Y that engages with the pin joint X, and an end having a sleeve 63a into which the tip of the roll shaft 33a is fitted. And a lid 63. The roll body 61 includes a core cylinder 61a, a cushion layer 61b such as a sponge that is externally fitted or bonded to the core cylinder 61a, and a loop surface fastener 61c that is externally fitted or bonded to the cushion layer 61b. . As is well known, the loop surface fastener 61c is a surface fastener having a large number of flexible loops R that are hooked on a hook fastener or a mushroom fastener. As shown in FIG. A large number of flexible loops R are woven on the surface of a support (woven fabric) U. The arrangement direction of the loop R is substantially oriented in the circumferential direction of the polishing rice roll 60. Further, as shown in FIG. 18B, it is desirable that the loop R in the plan view of the loop row and the loop R in the plan view of the adjacent loop row intersect at an obtuse angle φ of 120 °, for example.

  The end lid 70 has an octagonal shape and includes a bearing 71 that rotatably receives the sleeve 63a. A bow-shaped polished rice discharge port 72 is formed at the lower portion of the end lid 70 to communicate with the discharge rod 11b.

  After the grinding roll 60 is slid into the removal cylinder 50 to engage the pin joint X and the groove joint Y and the tip of the roll shaft 33a is fitted into the sleeve 63a, the end lid 70 is attached to the removal cylinder 50. Fix to the opening frame 54. In this state, the roll shaft 33a is supported at both ends by bearings 53b and 71. The assembly presser 38 is closed so as to straddle the end lid 70, and fastened with two knob bolts 37. Then the posture of the polished rice unit 20 is changed from the horizontal posture to the inclined posture, and the flip-up type door body is closed.

  In this state, when the motor 2c of the cerealing device 2 and the motor 4 for polishing rice are activated by the operation of the operation panel 11a, the white rice is removed through the third pyramidal hopper receiver 10 and the dropping port 53a. It is dropped into the gap between the 50 cylindrical body 52 and the rotating polishing roll 60. Here, the white rice dropping opening 53a is formed at the boundary between the dehulling net 51 and the non-hulling part 51a, and the polishing rice roll 60 rotates in the direction from the non-hulling part 51a to the dehulling net 51 at the white rice dropping hole 53a. Therefore, it becomes easy for white rice to enter the gap. As shown in FIG. 18 (A), the charged white rice grains Z are wiped off by the loop R of the loop surface fastener 61c, and are removed by centrifugal force while receiving a circumferential force and rotating spirally. While being rubbed against the net 51, the polished rice is discharged from the discharge rod 11b through the polished rice discharge port 72.

  The loop hook-and-loop fastener 61c is more durable than the brush, and the bristles of the brush are polished so that the surface of the white rice is scratched linearly, whereas many loops R of the loop hook-and-loop fastener 61c are the surface of the white rice grain Z. As the rice bran is scraped off in a loop area, the removal area of the rice cake adhering to the surface of the white rice grains Z is enlarged, and the rice polishing performance is greatly improved. In addition, as shown in FIG. 18B, when the loop R in the plan view of the loop row and the loop R in the plan view of the adjacent loop row intersect at an obtuse angle φ, Capturing can be performed between the two loop rows, and a polishing function and a circumferential feed function can be exhibited. The number of rounds of white rice grains in the dehuller 50 is improved, and the polishing performance is greatly improved. Further, since a relatively thick cushion layer 61b exists as a lower layer of the loop surface fastener 61c, the cushion layer 61b sinks at the position of the white rice grain Z, and the white rice grain Z is used for boiling by a number of loops R. The sharpening performance is greatly improved. The soot adhering to the loop R is screened out by vibrations generated in the apparatus and discharged from the dehiding net 51.

In this example, as shown in FIG. 9, the inclination angle θ of the axis L ₁ of the polished rice section 20 from the vertical line L ₂ is set to 45 °. If the inclination angle θ is too large, the horizontal posture is approached, so that the number of times white rice circulates in the dehuller tube 50 increases, the residence time is long, the rice polishing process time is prolonged, and it is more likely to be over-polished rice. On the other hand, if the inclination angle θ is too small, it approaches a vertical posture, so the falling speed of white rice is fast, the number of laps is reduced, and it is easy to be in an unpolished state. It was found that the inclination angle θ is preferably in the range of 35 ° to 55 °. Desirably, 40 ° to 50 ° is preferable, but in this example, the angle is set to 45 ° in order to eliminate the trouble of designing the rice polishing machine.

  In addition, you may provide a loop hook-and-loop fastener also in the non-removal part 51a which is the upper half circumference of the fixed side removal cylinder 50. FIG. As a result, the white rice grains can be wiped off almost simultaneously with a large number of loops, and the polishing performance is further improved.

  FIG. 19 is a perspective view showing a polished rice roll according to Example 2, FIG. 20 is a front view showing the end of the polished rice roll, FIG. 21 is an exploded perspective view of the polished rice roll, and FIG. It is a perspective view which shows the removal aspect of the polished rice sheet | seat provided in the non-removal part of a pipe | tube.

  The difference from the first embodiment in this example is in the polishing rice roll 80 and the polished rice sheet 90 provided in the non-removal portion 51a of the dehulling cylinder 50, and the other points are the same as in the first embodiment. The description is omitted.

  The polishing roll 80 includes a cylindrical roll body 81, an end cover 62 having a groove joint Y that engages with the pin joint X, and an end cover 63 having a sleeve 63a into which the tip of the roll shaft 33a is fitted. The roll body 81 includes a core cylinder 81a, a cushion layer 81b such as a sponge bonded to the core cylinder 81a, and a loop surface fastener 81c that is in close contact with the periphery of the cushion layer 81b. A pair of long holes 82 are formed in the core cylinder 81a and the cushion layer 81b along a generatrix having a positional relationship of about 180 ° with respect to the center of rotation. The single loop hook-and-loop fastener 81c has an endless belt shape in which both ends are connected. After the endless belt-like loop fastener 81c covers the cushion layer 81b, the curved margin portion M of the loop hook-and-loop fastener 81c is long. The loop surface fastener is placed on the cushion layer 81b so as to be pushed into the cylindrical space through the holes 82, and the mandrel N is inserted inside the curved margin portions M, and the coil spring 83 is hooked on both mandrels N so as to approach each other. 81c is stuck. As shown in an enlarged view in FIG. 20, the loop row of the flexible loop R of the loop surface fastener 81 c is oriented in the roll rotation direction, but many flexible loops R are inverted with their tips inclined in the roll rotation direction. It has become an eye. FIG. 20 shows the coil spring 83 on the end lid 63 side, but a similar coil spring is also used on the end lid 62 side.

  When the rice polishing process is performed for a certain period, wrinkles also adhere to the loop surface fastener 81c, and the polishing ability is deteriorated or the loop surface fastener deteriorates. Therefore, it is necessary to replace the loop surface fastener 81c. At the time of the replacement, the curved roll margin can be obtained simply by pulling out the polishing roll 80 from the removal cylinder 50, removing the coil spring 83 in the inner space of the core cylinder 81a from the spindle N, and pulling out the spindle N from the curved margin portion M. The portion M can be pulled out of the cushion layer 81b from the long hole 82, and the endless belt-like loop surface fastener 81c can be easily removed from the polished rice roll. For this reason, it becomes possible to clean or clean only the loop surface fastener 81c as a polished rice material. When attaching an endless belt-like loop surface fastener 81c after cleaning or washing or a new endless belt-like loop surface fastener 81c to the polishing rice roll, a curved margin is provided after the polishing roll is placed in the endless belt-like loop fastening fastener 81c. The loop surface fastener 81c is brought into close contact with the cushion layer 81b by inserting the portion M into the inner space through the long hole 82, inserting the mandrel N into the curved margin portion M, and hooking the coil spring 83 on the mandrel N. Can do. The cushion layer 81b also serves to prevent the loop surface fastener 81c from slipping.

  On the other hand, as shown in FIG. 22, a pair of guide grooves 51c (only one is shown) is provided with a guide frame Q at the boundary between the removal net 51 and the non-removal portion 51a of the removal cylinder 50. . These guide grooves 51c are inserted with both edges of the polished rice sheet 90 bent in a tunnel shape so that the polished rice sheet 90 can be slid and moved to the inner side of the removal cylinder 50. It is in close contact with the non-removal portion 51a. As shown in FIG. 23A, the polished rice sheet 90 has a flat plate shape in which a loop surface fastener 92 is pasted on one side of a rectangular flexible plastic sheet 91 and the edges are sewn together. As shown, it can be easily bent into a tunnel. The loop rows of the flexible loops R of the loop surface fastener 92 are oriented in the roll rotation direction, but many of the flexible loops R have opposite ends with their tips inclined in the roll rotation direction.

  If the polishing process is performed for a certain period of time, wrinkles also adhere to the loop surface fastener 92 and the polishing ability is reduced or the loop surface fastener 92 is deteriorated. Therefore, the loop surface fastener 92 needs to be replaced. At the time of this replacement, if the assembly presser 38 is removed, the polished rice sheet 90 attached to the non-removal portion 51a can be pulled out while sliding forward from the guide groove 51c. For this reason, the loop surface fastener 92 on the flexible plastic sheet 91 can be cleaned or cleaned. When the cleaned or washed polished rice sheet 90 or a new polished rice sheet 90 is mounted on the dehuller, the edges of the polished rice sheet 90 are inserted into the pair of guide grooves 51c in the state of being bent in a tunnel shape, toward the back. When the hand is slid and released, the polished rice sheet 90 can be loaded in close contact with the non-thickened portion 51a by its elastic restoring force.

  Since the guide frame Q covers both edges of the loop surface fastener 92 on both ends of the polished sheet 90, it is possible to prevent the peeling operation of the loop surface fastener 92 from the flexible plastic sheet 91 accompanying the roll rotation.
