Description

  The present invention relates to a coin rice milling machine that processes brown rice brought by the user according to the input of a usage fee, and more specifically, a dry-type non-washing rice processing machine is disposed in the subsequent process of the rice milling machine, The present invention relates to a coin rice mill that can be processed into both non-washed rice or ordinary rice that has not been subjected to no-wash rice processing, depending on the choice of the user.

  In recent years, it is not necessary to sharpen rice before cooking rice, and washing-free rice that can be cooked as it is has come to be used. However, non-washed rice is sold only at supermarkets and rice grain stores, and a coin-milling machine that can be washed-free according to the choice of customers is desired for coin milling machines that are increasingly used by general consumers. ing. For this reason, Patent Document 1 discloses an example of a coin rice mill that enables processing of unpolished brown rice into washing-free rice. This is a non-washing rice processing machine arranged in the post-process of the rice milling machine, making it possible to easily wash the brown rice with the same operation method as a conventional coin rice milling machine, The specific method for producing no-wash rice was not specified.

  There are three conventional washing-free rice production methods: a water-polished rice finishing method, a special processing finishing method, and a dry polishing rice finishing method. The water-polished rice finishing method is a method in which polished white rice is washed with water to wash away the rice bran layer remaining on the surface of the white rice, and immediately after that, dehydrated and dried to remove moisture from the white rice and finish it into non-washed rice. . The special processing finish method is to slightly add water to the polished white rice, soften the surface of the white rice surface, make it easy to peel, mix and stir a special rice bran adhesive, This is a method in which, after adsorbing to the koji adhering agent, the white rice and the koji adhering agent are separated and selected to finish washing-free rice. The dry-type polished rice finishing method is a method in which the surface of polished white rice is polished with a brush or the like to remove the cocoon layer and finish to wash-free rice.

The equipment for the hydrofinishing and special finishing methods uses a large amount of water in the hydrofinishing finishing method and uses a koji adhering agent in the special finishing method. together for greater burden on the maintenance, to the built-in within the building of the coin rice mill of the limited space, it is impossible. On the other hand, if it is a dry-type polished rice finishing system, water is not used, so the size of the system can be reduced, and it can be stored in the coin milling machine, and the cost is lower than the above two systems, and maintenance is also possible. The above burden can be reduced.
Japanese Patent Laid-Open No. 2003-24804

  In the dry-type polished rice finishing system, the rice bran that has not been completely removed during the rice polishing process, which is the previous process, is removed by polishing it with a brush. Is discharged. This koji has finer particles than the koji produced during the rice milling process and is called skin koji.

  In the conventional coin milling machine, the slag generated in the rice milling process is sucked by a fan for removing rice and then separated from the air by a cyclone separator connected to the discharge-side tip of the fan for removing the iron. Collected in flexible container bags and mansion rooms. However, skin flesh is fine and close to a light powder, so the cyclone separator used in the rice milling process cannot completely separate flesh and air. Will be scattered outside, and the surroundings will be soiled. For this reason, it is common to use a dust collector or the like with an excellent collection function as a suction means. However, if it is built in the coin mill of a limited space, the installation space will not be enough, and other equipment There are problems that maintenance is not possible and costs are high.

  Therefore, the present invention has been made based on the above circumstances, and occurs in the rice milling process in addition to being able to treat the brown rice brought by the user to both ordinary rice or non-washed rice by the user's selection. An object of the present invention is to provide a coin rice milling machine that can completely recover the koji and the skin koji generated in the non-washing rice treatment, and incorporates a non-washing rice processing machine that realizes space saving and low cost of mechanical equipment.

In order to achieve the above object, the invention according to claim 1 of the present invention divides a building into a guest room and a machine room with a partition wall, and the machine room is provided with machined brown rice introduced from the brown rice inlet of the guest room. Generated from a rice mill, a conveyor device to be taken into the room, a stone remover, an elevator, a rice mill, a dry-type washing-free rice processing machine, a discharge means for discharging the washing-free rice into a white rice tank on the guest room side And a cyclone separator for recovering skin scum generated from a dry-type washing-free rice processing machine, and a rice mill with a rice cake recovery duct and a rice flow path at the outlet side at least with the white rice tank side There is a flow path switching means for switching to the washing-free rice processing machine side, the dry washing-free rice processing machine has a skin recovery duct, and on the suction side of the dehulling fan connected to the discharge side a cyclone separator, Connect the wrinkle recovery duct and the skin wrinkle recovery duct respectively. And Hadanuka can be sucked at the same time, after rice treated rice mill brown rice, when pre-washed rice treated with pre-washed rice processor, after the rice processing completion, bran removing fan is stopped, then rice mill a certain time After running empty, discharging residual white rice and supplying it to the washing-free rice processing machine, it stops, and when washing-free rice processing is completed, the washing-free rice processing machine runs idle, and at the same time, the dehuller fan is restarted and washing-free rice The washing machine is characterized in that the washing machine and the dehulling fan are stopped after the treating machine has been idle for a certain period of time to discharge the washed rice to the white rice tank .

  Here, the dry-type non-washing rice processing machine is a concept that includes all adopting the dry-type polished rice finishing method as the manufacturing method of the non-washed rice, and the configuration and the like are not particularly limited. The flow path switching means is a concept including all means for switching the rice flow path processed by the rice milling machine between the white rice tank side and the dry-type non-washed rice processing machine side, for example, using the natural flow of rice It may be a device that switches the flow path, may be a device that has a transfer function in addition to the flow path switching function, may be configured from a single device, or may be configured by combining multiple devices. May be. Further, the discharging means is a concept including all means for discharging the white rice treated with the dry-type non-washing rice processing machine into the white rice tank, for example, having a conveyance function such as a pipeline or an elevator. Can be mentioned.

The invention according to claim 2 of the present invention is an adjustment valve for adjusting the suction force on either the heel recovery duct side or the heel recovery duct side at the connection part of the heel recovery duct and the heel recovery duct Is provided. Here, as an adjustment valve, the valve etc. which change the cross-sectional area (opening area) of each duct are mentioned, for example.

According to the first aspect of the present invention, a dry-type non-washing rice processing machine is provided on the outlet side of the rice milling machine via the flow path switching means, so that one rice milling machine can perform the same processing as normal rice processing. It can be used for both rice-washing treatments, and since it does not use a large amount of water or special organic substances when performing rice-free rice treatment, it reduces the burden on hygiene and maintenance, as well as machinery and equipment. This makes it possible to save space and to incorporate a dry-type non-washing rice treatment machine at a low cost without greatly modifying the conventional coin milling machine. In addition, the specific gravity inside the dehuller fan is reduced by simultaneously sucking the relatively high specific gravity of the rice cake generated from the rice mill and the lighter skin with low specific gravity generated from the dry-type non-washing rice processing machine. Different folds and skin folds are mixed moderately, and the cyclone separator can completely separate the folds, skin folds, and air. As a result, the skin folds are scattered to the outside along with the exhaust of the cyclone separator. It is possible to reliably prevent the soiling. In addition, since a separate dust collector for the skin mill is not required in the coin milling machine, the machine equipment can be saved in space and sufficient space is secured in the coin milling machine. In addition, the cost of the mechanical equipment can be reduced. In addition, by restarting the dehulling fan, it is possible to clean the dehulling stains built in the rice milling machine and the wrinkles and skin wrinkles attached to the dehulling wire mesh built in the non-washing rice processing machine, thereby reducing maintenance.

According to the second aspect of the present invention, the connecting portion between the wrinkle recovery duct and the skin wrinkle recovery duct is for adjusting the suction force on either the wrinkle recovery duct side or the skin wrinkle recovery duct side. Since the adjustment valve is provided, it is possible to adjust the mixing ratio of the rice bran from the rice milling machine and the skin koji from the non-washing rice processing machine when sucking.

  Hereinafter, an embodiment of a coin milling machine incorporating a dry type non-washing rice processing machine of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the coin milling machine of the present invention is installed in a building 4 that is partitioned into a guest room 1 and a machine room 2 by a partition wall 3. It has a brown rice inlet (brown rice input hopper) 5 for introducing the brown rice brought in, a white rice tank 6, and an operation panel 7. The machine room 2 has a brown rice intake conveyor 8, a first elevator 9, a stone remover 10, and a second elevator. 11. Consists of a rice mill 12, a flow path switching device 13, a dry-type non-washing rice treatment machine (anhydrous rice treatment machine) 14, and a collecting cyclone 15 for storing rice straw generated from the rice mill 12 and the anhydrous rice washing machine 14. Has been.

  The brown rice input hopper 5 has a brown rice intake conveyor 8 disposed in the lateral direction at the bottom. The brown rice take-in conveyor 8 rotates the screw shaft 17 with a motor in a case 16 connected to the brown rice charging hopper 5. The case 16 has a U-shaped cross section on the upstream side and a cylindrical shape on the downstream side. The brown rice taken from the upstream side is sent to the downstream side by the rotation of the screw shaft 17, and the first is passed through the pipe line K1 by the height difference. Pour into the lower entrance of the elevator 9.

  The first elevator 9 is a bucket conveyor that pulls up brown rice, and a large number of buckets 20 for pumping brown rice are attached to a belt 19 spanned between upper and lower pulleys 18 and 18 at intervals. The bucket 20 that has drawn the brown rice rotates along the upper pulley 18 when turning from rising to lowering, thereby throwing the brown rice into the pipe K2.

  The stone remover 10 has a hopper 21 at the upper portion thereof, and a sorting plate 22 inclined in the height direction is supported on the lower end side of the hopper 21 so as to be swingable. A fan 23 is located below the sorting plate 22. It is arranged. The sorting plate 22 has a large number of holes (not shown) over the entire circumferential surface. When the wind from the fan 23 blows from the bottom to the top of the sorting plate 22 while swinging in a state where the sorting plate 22 is tilted, the stone waste sinks due to the specific gravity difference between the stone waste and the brown rice, and the sorting plate 22 The rock waste gathers above the sorting plate 22 due to the swinging of the rice, and it is detected that the brown rice to which the brown rice detection sensor (not shown) provided at the back side of the brown rice throwing hopper 5 is thrown out disappears. When the stone gate 24 provided above the sorting plate 22 is opened, the stone waste falls and is collected in the collection box 26 through the first switching valve 25 and the pipe line K3. Then, when the first switching valve 25 is switched after the debris is dropped, a small amount of brown rice (residual brown rice) remaining on the sorting plate 22 from which the debris has been removed is sent to the receiving port of the second elevator 11 via the pipe K4. It is done. On the other hand, the brown rice is slightly lifted on the sorting plate 22 by the wind, is pushed by the brown rice supplied later, is sent downstream along the inclination of the sorting plate 22 and falls. The fallen brown rice is sent to the receiving port at the lower part of the second elevator 11 through the pipe K5 provided at the outlet 27.

  The second elevator 11 has substantially the same structure as the first elevator 9, and the brown rice sent from the stone removing machine 10 is taken into the receiving port of the second elevator 11 and pulled up by the second elevator 11, and the pipeline It is sent to the hopper 28 of the rice mill 12 through K6.

As shown in FIG. 3, the rice mill 12 has a hopper 28 at the top, and a milling chamber 29 is connected below the hopper 28. The milling chamber 29 is provided with a milling roll 30 and a scouring net 31. While the brown rice is fed by the milling roll 30 rotating in the milling chamber 29, the resistance plate 33 pressurizes the outlet 32 of the milling chamber 29. However, in the closed state, the white rice and rice bran are separated by rubbing between the unpolished rice and rubbing on the mesh of the dehulled net 31. Below the pearling chamber 29 connects the front portion of the bran collecting ducts 34, in the middle of the room bran collecting duct 34 are a built is Jonuka fan 35, turning the bran removing fan 35 by the motor, bran removing As a result of the suction action of the fan 35, the soot passes through the mesh of the soot 31 and is collected in the collecting cyclone 15 connected to the end of the soot collecting duct 34. On the other hand, the remaining white rice goes to the exit 32 of the scouring chamber 29, but the resistance plate 33 closes the exit 32 using the elasticity of the spring 36, and the white rice fed by the scouring roll 30 blocks the resistance plate 33. It pushes against the elastic force to open the outlet 32, and the white rice that has passed through the outlet 32 is sent to the case outlet 37. The case discharge port 37 provided with the second changeover valve 38, and conduit K7 leading to white rice tank 6, to a conduit K9 leading to conduit K8 anhydride RICE processor 14 leading to the receiving port of the second elevator 11 It branches off to the flow path switching device 13 for switching the flow path. The flow path switching device 13 is used to switch the open state of the pipe K9 leading to the anhydrous rice washing machine 14 to send the polished white rice to the anhydrous rice washing machine 14, and at the start and end stages of the rice polishing. Is used to circulate brown rice by switching to a state where the pipe K8 leading to the receiving port of the second elevator 11 is opened. A rice milling sensor 39 is provided at the lower part of the hopper 28. When the rice milling sensor 39 detects brown rice, the milling roll 30 is rotated to mill the rice. Otherwise, the milling roll 30 stops rotating. Further, an overflow sensor 40 is provided at the upper part of the hopper 28. When the overflow sensor 40 detects brown rice, the control of the operation panel 7 stops the driving of the brown rice intake conveyor 8, and the overflow sensor 40 turns the brown rice. Is not detected, the brown rice intake conveyor 8 continues to rotate.

  The opening / closing structure of the resistance plate 33 will be described in more detail. In order to adjust the degree of whitening and to discharge the brown rice, the arm 41 is supported in the vicinity of the exit 32 of the milling chamber 29 so as to be able to swing around its center, and one end of the arm 41 can be pressed and released by the pressing means 42. A resistance plate 33 provided at the other end of the arm 41 is provided so as to be able to open and close the outlet 32 by utilizing the pressing and releasing thereof.

  The pressing means 42 changes the degree of compression of the spring 36 and opens and closes the outlet 32. A resistance motor 43 is disposed outside the squeezing chamber 29, and a screw shaft 44 is directly connected to the resistance motor 43. The nut 45 and one end of the arm 41 are screwed at an interval, and a spring 36 passed through the screw shaft 44 is interposed between the nut 45 and one end of the arm 41 so that the nut 45 is not rotatable in the circumferential direction. Thus, the nut 45 can be moved forward and backward as the screw shaft 44 rotates forward or backward. Therefore, the compression degree of the spring 36 is changed by rotating the resistance motor 43 based on the operation signal of the operation panel 7 and moving the nut 45 forward and backward as the screw shaft 44 rotates. For this control, a convex portion 46 is provided at the end of the screw shaft 44 and a convex portion detection sensor 47 is provided around the end, and the number of rotations of the resistance motor 43 is controlled based on information obtained from the sensor 47. . Further, in order to determine the minimum and maximum degree of compression of the spring 36, the detected object 48 protrudes from the nut 45, and the detected object 48 is opposed to the forward limit switch 49 and the backward limit switch 50 made up of limit switches. The movement range is regulated. When the degree of compression of the spring 36 is minimum, the spring 36 is not expanded or contracted at all, and the nut 45 is in the retreat limit position, the pressing force of the spring 36 is released, and the resistance plate 33 is opened. A gap is formed between the outlet 32 and the brown rice is discharged as it is from the gap. Then, by moving the nut 45 forward with the position of the retreat limit as the origin, the degree of compression of the spring 36, and consequently the pressing force applied in the direction in which the resistance plate 33 closes the outlet 32 is increased, and the whitening is performed according to the pressing force. The degree is determined.

  As shown in FIG. 4, the flow path switching device 13 has a rotating shaft 52 provided in a horizontally oriented cylindrical case 51 so that the rotating shaft 52 can rotate forward and backward. The rotating shaft 52 is a motor 53 provided outside the cylindrical case 51. To rotate. The rotating shaft 52 is provided with a spiral body 54 having a lead for conveying brown rice or white rice to one end side or the other end side of the rotating shaft 52. The cylindrical case 51 has a loading port 55 at the longitudinal center portion thereof, and drop ports 56a and 56b are provided on the left and right sides of the cylindrical case 51, respectively, and the conduit K8 leading to the receiving port of the second elevator 11 and the anhydrous rice cleaning process. Each is connected to a pipeline K9 leading to the machine 14. Brown rice or white rice is conveyed by a thrust action generated by the rotation of the spiral body 54. When the rotating shaft 52 is rotated forward by the motor 53, the brown rice or white rice is moved to the pipe K 8 side leading to the receiving port of the second elevator 11. When the brown rice is conveyed and dropped from the dropping port 56a and the motor 53 is reversed, the white rice is transferred to the side of the conduit K9 leading to the anhydrous rice washing machine 14 and dropped from the dropping port 56b.

The anhydrous rice-washing processing machine 14 is configured such that a dry-type non-washing rice production apparatus previously filed by the present inventor (Japanese Patent Application No. 2003-376509) can be installed in a coin rice mill, as shown in FIG. The rotary shaft 58 is rotatably provided in the longitudinal direction in the body case 57, a motor 59 is installed in the vicinity thereof, and the rotary shaft 58 is rotationally driven via the conduction means 60 provided at the lower end of the rotary shaft 58. A lifted rice helix 61 for transferring white rice upward is provided on the lower side of the rotating shaft 58, and a short brush helix 62 having a lead for transferring white rice upward and a resin brush (brush diameter: Polishing brush formed in a substantially cylindrical shape by flocking 0.05 mm to 0.5 mm (preferably 0.2 mm to 0.3 mm) and brush length: 3 mm to 30 mm (preferably 11 mm to 13 mm) at high density. A plurality of 63 are mounted alternately. Further above that, a discharge spiral 64 for transferring the white rice upward is provided. A cylindrical rice milling cylinder 65 is provided on the outer periphery of the rice milling spiral 61 with an appropriate gap, and an opening 67 communicating with a hopper 66 outside the machine body case 57 is provided on the lower end side thereof. A cylindrical discharge cylinder 68 is also provided on the outer periphery of 64, and an outlet 69 provided thereabove is provided with a pipe line K 10 that leads to the white rice tank 6. In addition, a cylindrical metal mesh 70 made of a slit-shaped porous member is provided between the raised rice cylinder 65 and the discharge cylinder 68 with a gap slightly wider than the outer circumference of the polishing brush 63 and the thickness of the rice grains. A plurality of convex resistors (not shown) are provided at equal intervals on the inner surface of the wire mesh 70 so as to be orthogonal to the rotation direction of the polishing brush 63. A body removal chamber 71 surrounded by a partition wall is formed inside the machine body case 57 corresponding to the outer peripheral portion of the wire removal wire mesh 70, and a front portion of the skin recovery duct 72 is connected to the lower side of the removal chamber 71. The end of the soot recovery duct 72 is connected to the soot recovery duct 34 (see FIGS. 1 and 3) connected to the rice mill 12 on the intake side of the soot removal fan 35. The fine skin husk removed from the surface of the white rice passes through the mesh of the wiping wire mesh 70 and is collected by the collecting cyclone 15 connected to the end of the cocoon collecting duct 34 while being mixed with the husk from the rice mill 12. The An air hole (not shown) for taking outside air is formed in the outer periphery of the removal chamber 71 at a position opposed to the skin recovery duct 72, and an air flow is generated along the outer periphery of the removal metal mesh 70. Skin wrinkles that easily adhere to the outer periphery of the wire mesh 70 are also completely recovered.
Here, an adjustment valve for adjusting the suction force of either the wrinkle collection duct 34 side or the skin wrinkle collection duct 72 side is provided at a connection portion between the wrinkle collection duct 34 and the skin wrinkle collection duct 72, for example, each duct 34. , 72 may be provided with a valve or the like that changes the cross-sectional area (opening area), so that the mixing ratio of the rice bran from the rice milling machine 12 and the skin koji from the anhydrous rice processing machine 14 during suction can be adjusted. .

  The white rice supplied to the hopper 66 of the anhydrous rice washing machine 14 flows into the raised rice cylinder 65 and is sent upward by the raised rice helix 61 in the order of the brush helix 62 and the polishing brush 63. The polishing brush 63 itself has almost no function of fried rice because resin brushes are planted at high density. Therefore, around the polishing brush 63, the moving speed in the rice lifting direction decreases, and the surface of the white rice is easily subjected to the polishing action of the polishing brush 63. For this reason, the brushing effect by the polishing brush 63 is increased due to a large speed difference from the polishing brush 63 rotating at high speed. In addition, the density of white rice is increased around the polishing brush 63. Therefore, the white rice itself repeatedly revolves around the polishing brush 63 due to the collision between the white rice, and the back and front surfaces of the white rice are uniformly polished by the polishing brush 63. Will receive. However, even if the moving speed in the frying rice direction decreases around the polishing brush 63, if the polishing brush 63 is swung and the white rice also swirls on the inner surface of the demetalization wire net 70, the polishing by the polishing brush 63 is sufficient. It becomes difficult to receive. Therefore, a convex resistor is provided on the inner surface of the metal strip 70 so as to be orthogonal to the rotation direction of the polishing brush 63, thereby preventing the polishing brush 63 from being hardly subjected to polishing. That is, the white rice that is about to be rolled while being swung by the brush spiral 62 and the polishing brush 63 is first decelerated by the polishing brush 63 in the moving direction in the rice lifting direction. Therefore, the turning speed in the turning direction can be suppressed, so that the polishing by the polishing brush 63 can be sufficiently received. In addition, since a plurality of polishing brushes 63 are arranged on the rotating shaft 58, the above-described brushing is repeated for the number of the polishing brushes 63 arranged. By the time it passes through 63, the wrinkles on the surface of the white rice are completely removed, resulting in a high quality non-washed rice.

  As shown in FIGS. 6 and 7, the operation panel 7 has an operation panel 73 on the front surface and an administrator panel 74 on the back surface, and has a control device (not shown) composed of a microcomputer inside. Based on the operation of the operation panel 73 or the administrator panel 74, the control device outputs a control signal to the motors 43, 53, 59, the switching valves 25, 38, the flow path switching device 13, etc. of each part, or sets the set values of each part. Or change it.

  As shown in FIG. 6, the operation panel 73 selects an operating lamp 75, a malfunctioning lamp 76, a coin insertion slot 77, a charge indicator lamp (100-yen coin insertion number) 78, a no-wash rice switch 79, and a degree of milling. Three whiteness switches 80, a rice milling indicator lamp 81, and a fee shortage indicator lamp 82 are installed.

  The administrator panel 74 opens and operates the operation panel 7 supported by a hinge or the like so that it can be opened and closed. As shown in FIG. 7, in addition to a switch for setting the whitening degree (whitening degree setting switch) 83, A usage fee collection switch 84, an ordinary rice transfer amount setting switch 85, a no-wash rice transfer amount setting switch 86, an unwashed rice use counter 87, and the like are installed.

  Next, the operation of the coin rice mill of the present invention will be described. This coin-milling machine can process brown rice brought by a user into either normal rice or non-washed rice according to the user's selection. First, the operation of subjecting brown rice to normal rice polishing will be described. This coin mill is provided with two switching valves 25, 38, a flow switching device 13, and a stone removal gate 24. In the initial state, the first switching valve 25 opens the pipe K3, and the second switching valve. 38 is set so that rice flows to the flow path switching device 13 side and the flow path switching device 13 to the second elevator 11 side, respectively, and the stone removal gate 24 is closed.

  When the business indicator lamp 75 is lit, when the user inserts a coin into the coin insertion slot 77 according to the amount of brown rice to be processed, the coin number is displayed in the charge indicator lamp 78, and at the same time there is nothing. The rice-washing switch 79 and the three whiteness switches 80 are blinked and are ready to accept. In response to this, the user puts the brown rice into the brown rice throwing hopper 5 and presses the desired whiteness switch 80. Then, the milled rice indicating lamp 81 is turned on, and the brown rice intake conveyor 8, the first elevator 9, the stone remover 10, and the second elevator 11 are driven. The rice milling machine 12 rotates the resistance motor 43 in response to the whiteness switch 80 to change the compression degree of the spring 36 to determine the closing state of the resistance plate 33, and the second switching valve 38 at the outlet of the rice milling machine 12 is The flow path switching device 13 side is held in an open state, and the flow path switching device 13 rotates the motor 53 so as to convey it to the conduit K8 toward the second elevator 11 to remove brown rice and unpolished rice in the second elevator. The operation starts so as to circulate between 11 and the rice mill 12.

  When the brown rice is supplied to the hopper 28 of the rice mill 12 and the rice milling sensor 39 detects the brown rice, the control device starts timer counts T1 and T2, and after T1, the milling roll 30 and the dehulling fan 35 are turned on. To drive. Along with this, the rice milling process is started, but brown rice and unmilled rice at the early stage of milling return to the hopper 28 of the rice mill 12 again from the second elevator 11 via the second switching valve 38 and the flow path switching device 13. When the timer count T2 ends, the second switching valve 38 at the exit of the rice mill 12 is switched so as to open the white rice tank 6 side, and the white rice is discharged into the white rice tank 6 through the pipe K7. When the overflow sensor 40 of the hopper 28 of the rice mill 12 outputs a full signal, the drive of the brown rice intake conveyor 8 is stopped. When the overflow sensor 40 outputs a non-full signal, the drive of the brown rice intake conveyor 8 is stopped. To resume. The rice milling process is continued until all of the brown rice loaded by the brown rice taking conveyor 8 is taken up.

  When the amount of brown rice in the hopper 28 of the rice milling machine 12 decreases and the rice milling sensor 39 no longer detects brown rice, the second switching valve 38 is switched again to open the flow path switching device 13 side. Residual brown rice in the hopper 28 or the rice mill 12 is returned to the second elevator 11 via the flow path switching device 13 and the pipe K8, and is supplied again to the hopper 28 of the rice mill 12 so that the second elevator 11 and the rice mill 12 Start circulating rice milling in between. This is because when the subsequent rice to the rice milling machine 12 disappears, the pressure in the rice milling machine 12 decreases, so that brown rice and unmilled white rice at the end of the rice milling process are discharged into the white rice tank 6, This is to prevent the remaining brown rice from being mixed with the white rice, and the residual brown rice is processed into white rice by circulating between the second elevator 11 and the rice mill 12 for a certain period of time. After the completion of the circular milling, the second switching valve 38 is switched again so that the white rice tank 6 side opens, and at the same time the white rice is discharged into the white rice tank 6, the resistance motor 43 rotates in the reverse direction, and the nut 45 is in the 0 point (origin) direction. The movement is started, the compression of the spring 36 is released, and the resistance plate 33 is opened. When the object to be detected 48 of the nut 45 turns the backward limit switch 50 to “ON”, the rotation of the resistance motor 43 stops and the fan removal fan 35 stops. When the removal fan 35 stops, the suction action disappears, so that the white rice remaining in the mesh of the removal residue 31 is easily discharged, and the rice mill 12 is tilted forward as a whole. The remaining white rice can be completely discharged into the white rice tank 6 by idling for a predetermined time. Residual white rice in the rice milling machine 12 is completely discharged into the white rice tank 6 and the idle operation of the rice milling machine 12 is terminated, whereby the operation of the coin rice milling machine is completed.

  Here, since the brown rice intake conveyor 8 rotates by the amount charged, brown rice remaining in the brown rice input hopper 5 remains when brown rice larger than the input fee is put into the brown rice input hopper 5. This is detected by a brown rice sensor (not shown) attached to the brown rice charging hopper 5, and the charge shortage indicator lamp 82 is turned on.

  Next, the operation | movement which carries out the washing-free process of the brown rice is demonstrated. Here, only the operation different from that in the case of ordinary rice processing will be described. When a coin is inserted into the coin insertion slot 77, the no-wash rice switch 79 and the three whiteness switches 80 blink to be ready for acceptance. In response to this, the user puts brown rice into the brown rice throwing hopper 5 and pushes the no-wash rice switch 79. Then, the indicator light 81 in the milled rice is turned on, and the brown rice intake conveyor 8, the first elevator 9, the stone remover 10, the second elevator 11, and the rice mill 12 are driven.

  Here, if the usage fee collection switch 84 of the administrator panel 74 is set to “permitted”, for example, if the usage fee per washing-free rice processing is set to 100 yen in addition to the ordinary rice processing, After waiting for 200 yen or more, the no-wash rice switch 79 blinks and is ready to accept. That is, only the whiteness switch 80 is in an acceptable state when only 100 yen is inserted, and the no-wash rice switch 79 is in an unacceptable state. After confirming the input of 200 yen or more, the no-wash rice switch 79 is lit, and when the no-wash rice switch 79 is pressed, a charge subtracting the charge per use from the charge is displayed on the charge indicator lamp 78, and the displayed charge The brown rice is taken into the machine by the brown rice take-in conveyor 8 and washed without washing. The usage fee per time may be set in advance, or the administrator panel 74 is provided with a usage fee setting switch, for example, a digital switch equivalent to the transport amount setting switches 85 and 86, and the administrator arbitrarily sets it. It may be possible.

  Upon receiving the signal from the non-washing rice switch 79, the rice mill 12 rotates the resistance motor 43 to a preset resistance value and closes the resistance plate 33 to a predetermined position, as in the case of ordinary rice processing. The second switching valve 38 is switched and the motor 53 of the flow path switching device 13 is rotated forward so that the brown rice and unmilled rice circulate between the second elevator 11 and the rice mill 12 for a certain period of time. The resistance value set in advance is equivalent to the upper whiteness or standard milling degree in the case of ordinary milled rice, and if the resistance value is set below the standard of milling degree, a lot of rice cake remains on the polished rice surface after the milling process. Thus, even if the washing-free rice treatment is performed in that state, the wrinkles are not completely removed from the surface of the white rice, and the washed rice with a reduced quality is finished. The degree of compression of the spring 36 is set in advance, but a whiteness setting switch dedicated for washing-free rice processing may be provided on the administrator panel 74 so that the administrator of the coin rice mill can arbitrarily set it.

  When the brown rice is supplied to the hopper 28 of the rice mill 12 and the rice milling sensor 39 detects the brown rice, the control device starts timer counts T1 and T2, and after T1, the milling roll 30 and the dehulling fan 35 are turned on. Simultaneously with the driving, the anhydrous rice treating machine 14 starts operation. When the timer count T2 ends, the rotation direction of the motor 53 of the flow path switching device 13 is reversed, and the white rice is conveyed to the side of the line K9 leading to the anhydrous rice washing machine 14. Then, the white rice that has been washed with no water by the anhydrous rice treatment machine 14 is discharged to the white rice tank 6 through the pipe K10. Here, the path connecting the anhydrous rice treatment apparatus 14 and the white rice tank 6 is not necessarily limited to the pipe line K10, and a conveying means such as an elevator may be provided between the anhydrous rice treatment apparatus 14 and the white rice tank 6. Good.

The rice milling process is continued until the brown rice taking conveyor 8 takes in all the brown rice for the input fee, and the rice milling sensor 39 of the hopper 28 of the rice milling machine 12 no longer detects the brown rice. When the amount of brown rice in the hopper 28 of the rice milling machine 12 decreases and the rice milling sensor 39 no longer detects brown rice, the rotation direction of the motor 53 of the flow path switching device 13 is returned to the normal rotation, and the residual in the rice milling machine 12 The brown rice is returned to the second elevator 11 via the pipe K8, and the circular rice milling between the second elevator 11 and the rice mill 12 is started. This is a control for preventing the brown rice and unmilled white rice at the end of the rice polishing from being supplied to the anhydrous washing rice processing machine 14 as in the case of the normal rice processing. When the circulation rice milling for a certain period of time is completed, the rotation direction of the motor 53 of the flow path switching device 13 is reversed again, the circulation rice milled white rice is supplied to the anhydrous rice washing machine 14, and the unwashed rice is further treated with the white rice tank 6. To discharge. At the same time, the resistance motor 43 rotates in the reverse direction and the nut 45 starts to move in the 0 point (origin) direction, and finally the rotation of the resistance motor 43 is stopped and the fan 35 is removed as in the ordinary rice milling process. Stops. Then, in order to completely discharge the residual white rice from the rice mill 12 and supply it to the anhydrous rice washing machine 14, the rice mill 12 is idled for a certain period of time, and then the operation of the rice mill 12 is stopped. After the operation of the rice mill 12 is stopped, the anhydrous rice washing machine 14 is idled, and the completely washed rice is discharged from the anhydrous rice treating machine 14 to the white rice tank 6 and the anhydrous rice washing machine 14 is idled. By ending, the operation of the coin milling machine is completed. In addition, at the same time as the anhydrous rice washing machine 14 started the empty operation, it was stopped for the purpose of cleaning the wrinkle residue 31 of the rice milling machine 12 and the wrinkles and skin wrinkles adhering to the periphery of the dehiding wire net 70 of the anhydrous rice washing machine 14. the bran-removing fan 35 Ru is operating again.
