  FIG. 1 is a schematic front view of a rice mill showing an embodiment of the present invention, and FIG. 2 is a partially cutaway schematic side view showing an internal structure of the rice mill. 1 and 2, a rice mill 1 of the present embodiment is provided with a plurality of moving casters 2 on a bottom surface, and on a gantry 5 on which a mounting table 4 of a refined product container 3 (paper bag) is projected at an intermediate position. A rice mill main body 6 of a horizontal axis type is placed on top of a raw material supply cylinder 7 of the rice mill main body 6, and a temporary storage hopper 8 for temporarily storing raw materials and a suction type graining machine 9 are stacked. It is characterized by having been provided.

  The rice milling machine main body 6 (see FIG. 2) includes a milling section 11 provided in the cover body 10 and a resistance provided at a rice grain discharge port side of the milling section 11 to apply resistance to a rice grain outlet by a spring bias. A control unit 12; a refined product discharge gutter 13 for guiding the refined products flowing out against the resistance control unit 12 to the outside of the machine; A main part is formed from the raw material supply cylinder 7 provided on the raw material supply side of the milling unit 11 and the motor 15 for rotating the milling roll and the grain feeding screw of the milling unit 11.

  The milling unit 11 is provided with a perforated wall bran refining cylinder 16 laid horizontally in the cover body 10, a main shaft 17 rotatably provided in the perforated wall bran refining cylinder 16, and mounted on the main shaft 17. A grain feeding screw 18 and a milling roll 19, a milling chamber 20 formed between the perforated-wall dehulling milling cylinder 16 and the milling roll 19, and a bran-removing unit formed outside the perforated-wall milling roll 16 And a chamber 21.

  The polishing chamber 20 has one end connected to a rice grain supply port 22 and the other end connected to a rice grain discharge port 23. The resistance adjuster 12 provided on the rice grain discharge port 23 side includes a resistance plate 24 for closing the rice grain discharge port 23, a spring member 25 for applying a resistance spring pressure to the resistance plate 24, and a spring pressure of the spring member 25. And a dial 26 for adjusting the distance. With this configuration, when the dial 26 is turned, the spring pressure of the resistance plate 24 is adjusted, and the whiteness of the polished rice can be set stepwise.

  A drive pulley 27 is mounted on an end of the main shaft 17, while a motor pulley 28 is mounted on a motor shaft of the motor 15, and a belt 29 is wound between the motor pulley 28 and the drive pulley 27. Have been. Thus, by driving the motor 15, the grain feeding screw 18 and the milling roll 19, which are mounted on the main shaft 17, are rotated, and the brown rice supplied to the rice grain supply port 22 passes through the milling unit 11. It is polished and refined. On the other hand, the bran peeled off from the brown rice leaks out of the perforated wall bran refining cylinder 16 and is collected in the bran collecting container (paper bag) 30 through the bran removing chamber 21 and the bran discharge gutter 14.

  The polished rice is discharged outside the machine against the resistance plate 24 closing the rice grain discharge port 23, and is collected in the refined product container 3 (paper bag) via the refined product discharge gutter 13.

  Next, the detailed structures of the temporary storage hopper 8 and the suction type fryer 9 which are provided on the upper part of the rice polishing machine main body 6 will be described with reference to FIG. FIG. 3 is a longitudinal sectional view showing the main parts of the temporary storage hopper and the suction type fryer.

  As shown in FIG. 3, a funnel-shaped temporary storage hopper 8 is laid on the upper part of the raw material supply cylinder 7 of the rice milling machine main body 6, and a suction type fryer 9 is laid on top of the temporary storage hopper 8. Is established.

  The suction type graining machine 9 includes a suction mechanism A having a suction machine 35 and a rice grain separation passage 36, a rice grain collection hopper 38 and an opening / closing lid opening / closing mechanism 40, and supplies the collected rice grains to the temporary storage hopper 8. The main part is constituted by the rice grain supply mechanism B and the suction hose part C.

  The suction mechanism A includes a vertical suction cylinder portion 34 having an air intake port 32 and an exhaust port 33 provided in the center of the housing 31A, a suction device 35 including a motor and a suction fan provided in the suction cylinder portion 34, Further, a rice grain separation passage 36 is formed on the outer peripheral side of the suction cylinder 34 and separates the rice grains from the air while rotating the rice grains.

  The rice grain supply mechanism B is housed in the housing 31B, communicates with the rice grain separation passage 36, and turns the rice grain. The rice grain swirl passage 37, and the rice grain collection hopper that collects the rice grains separated from the rice grain swirl path 37. 38, and a lid opening / closing mechanism 40 that opens and closes the lid 39 when the suction device 35 is in operation, and opens the lid 39 when not operating (normally). The rice grain supply mechanism B is separable from the suction mechanism A. For example, the rice grain supply mechanism B is provided with protrusions 45 on both side walls of the housing 31A, while the projections 45 are provided on the housing 31B side. A simple type of patchon key 46 may be attached to both side walls.

  Further, the suction hose portion C is provided with a suction nozzle 42 (see FIG. 1 or FIG. 2) which can be inserted into a container (rice bag for 30 kg) 41 packed with raw brown rice, and a length connected to the suction nozzle 42. It is provided with a long suction hose 43 and an insertion port 44 through which the base end side of the suction hose 43 can communicate with the rice grain separation passage 36.

  Next, the structure of the lid opening / closing mechanism 40 of the rice grain supply mechanism B will be described. One end of the opening / closing lid 39 forming the lid opening / closing mechanism 40 is rotatably mounted on a rotating shaft 47, and the other end is formed as a free end. As a result, the rice grain discharge port 48 of the rice grain collecting hopper 38 is opened in a state where the lid 39 hangs down due to its own weight (solid line position in FIG. 3). On the other hand, when the suction device 35 is operated, suction is performed from the air suction port 32 to the air discharge port 33, so that the inside of the rice grain collection hopper 38 becomes a negative pressure, and the opening / closing lid 39 causes the rice grain discharge port to resist its own weight. 48 is closed (the position indicated by the two-dot chain line in FIG. 3). When the suction device 35 is continuously operated in this state, the rice grains in the container (rice bag for 30 kg) 41 are sucked from the suction nozzle 42 of the suction hose section C and are fried, and the rice grains are inserted into the rice grain separation passage 36 from the insertion port 44. Is supplied.

  When comparing the processing capacity of milling of the rice milling machine main body 6 with the processing capacity of milling of the suction type milling machine 9, the suction type milling machine 9 has at least the minimum milling processing capacity of the rice milling machine main body 6. In order to carry out the above-mentioned milling, it is necessary to adopt a milling material having a milling processing capacity higher than the minimum milling processing capacity.

For example, assuming that the processing capacity of the milling of the rice milling machine main body 6 is 20 kg / h at the minimum and 40 kg / h at the maximum, the processing capacity of the milling of the suction type milling machine 9 is as follows. Desirably, the capacity is about 10 times 200 kg / h to 400 kg / h. However, if the graining capacity of the rice grains is excessive, there is a danger of overflow, overflow, and clogging phenomenon with respect to the rice milling machine 6, the temporary storage tank 8, and the suction-type graining machine 9. This problem does not occur if the intermittent lifting operation with the timer is repeated. Further, it the AgeKoku operation by the timer, when formed into an electrical control for stopping the AgeKoku operation by detecting the full amount of the temporary storage tank 8, and can be automated on-off start-up of the intermittent AgeKoku operation . Therefore, just below lid 39 of the lid closing mechanism 40 (see FIG. 3) is, per whether sump amount of rice grains full amount of the temporary storage hopper 8 performs detection and determination of the presence or absence of rice grains A photo sensor 49 may be provided. That is, when the amount of accumulation in the temporary storage tank 8 is L1 (the two-dot chain line in FIG. 3), it is in a sufficient state even when the grain lifting operation is continued, but the amount of accumulation is L2 (the two-dot chain line in FIG. 3). In this case, if the further frying operation is continued, the control may be performed to stop the frying operation on the assumption that a danger such as overflow, overflow, or clogging occurs. Control may be performed so that the frying operation is restarted when the accumulated amount decreases to L1.

  Next, an electrical control configuration of the suction type fryer 9 will be described with reference to FIGS. As shown in FIG. 1, the suction hose 43 of the suction-type fryer 9 is provided with an operation handle 50 for performing an operation of inserting the suction nozzle 42 into the container 41, and is operated on the operation handle 50. Push button switch 51 is provided. The push button switch 51 includes three types, an automatic button 53, a manual button 54, and a stop button 55, which are arranged on an operation panel board 52.

  Then, as shown in FIG. 4, manual ON / OFF control of the suction device 35 by operating the push button switch 51, timer control of the suction device 35, and automatic ON / OFF of the suction device 35 by detection of the photo sensor 49. A control unit 56 for performing control is located at the center. That is, the control unit 56 is provided with a timer circuit 57, the motor 35a of the suction device 35 is electrically connected to the control unit 56 via the AC power supply 58, and the photo sensor 49 is electrically connected to the control unit 56. , And the push button switch 51 is electrically connected to the control unit 56. Reference numeral 59 denotes a power lamp that lights red when the power is supplied, and reference numeral 60 denotes an operation lamp that lights green when the suction motor 35a is driven and in operation. Is electrically connected to

  FIG. 5 is a flowchart showing a control flow of the suction-type fryer. 5 will be described later, when the automatic button 53 on the operation panel substrate 52 is pressed, the photo sensor 49 and the timer circuit 57 are associated with each other to intermittently lift the suction type grain mill 9. Automation of the on / off start of the grain operation is realized, and when the manual button 54 on the operation panel board 52 is pressed, the amount of the grain of the suction type grain mill 9 by the timer circuit 57 is limited by the timer.

  FIG. 6 is a cross-sectional view showing the internal structure of the suction nozzle 42 of FIG. 1. FIG. 6A is a cross-sectional view of the suction nozzle 42 of FIG. 7) is a vertical cross-sectional view taken along the line BB in FIG.

  As shown in FIGS. 1, 6 (a) and 6 (b), the suction nozzle 42 can eliminate the clogging phenomenon due to suction by providing an air storage chamber 65 near the nozzle tip of the hollow cylindrical portion 61. You can do it.

  That is, the suction nozzle 42 includes a long hollow cylindrical portion 61 and a partition wall 62 that vertically divides the inside of the hollow cylindrical portion 61 into upper and lower portions, and the hollow cylindrical portion 61 partitioned by the partition wall 62. Is formed as a rice grain suction passage 63, and the other space is formed in an air storage chamber 64 for generating a suction wind.

  The suction passage 63 has a semicircular rice grain main suction port 65 at the tip of the hollow cylindrical portion 61, and a rice grain sub suction port 66 at one cylindrical side wall 61 a of the hollow cylindrical portion 61. ing.

  The air storage chamber 64 has a porous first air intake portion 67 formed on the other cylindrical side wall portion 61 b of the hollow cylindrical portion 61, and a porous second air intake portion 67 formed on the tip of the hollow cylindrical portion 61. The space is surrounded by the air intake section 68 and the partition wall 62. Reference numeral 69 denotes a communication port that communicates the suction passage 63 with the air storage chamber 64. When the air is sucked from the suction passage 63, the air in the air storage chamber 64 is sucked through the communication port 69. Therefore, if the air storage chamber 64 is not provided, the intake air is extremely small and the air is blocked. However, if the air storage chamber 64 is provided, the suction air can be generated by the presence of the intake air.

  Next, an example of the operation in the above configuration will be described based on FIG. 2, FIG. 3, FIG. 5, and FIG.

  First, a worker such as a farmer takes out one bag of the brown rice container (rice bag for 30 kg) 41 (see FIG. 2) stored in a brown rice cooler or the like, moves it to the vicinity of the gantry 5, and opens it. . Then, the open end of the rice polishing container (paper bag) 3 is supported by the container opening end support metal fitting 70 and set on the mounting table 4, and the bran collection container (paper bag) 30 is set on the gantry 5. In addition, the suction nozzle 42 is inserted into the container (rice bag for 30 kg) 41 to start the rice polishing operation.

  Next, the operator turns the dial 26 of the resistance adjusting unit 12 of the rice milling machine body 6 to appropriately set the whiteness of the milled rice, and drives the motor 15 to rotationally drive the grain feeding screw 18 and the milling roll 19. deep. In this state, the suction-type fryer 9 is driven to fry the raw brown rice.

  That is, referring to FIG. 5, when the operator presses the automatic button 53 of the suction type fryer 9, the controller 56 determines which button has been pressed (S1 in FIG. 5), and Is pressed (S2 in FIG. 5), the photo sensor 49 checks whether or not rice grains are accumulated in the temporary storage hopper 8 (S3 in FIG. 5). When it is confirmed that no rice grains accumulate on the photosensor 49, the suction device 35 is driven (S4 in FIG. 5).

  When the suction device 35 is driven, suction is performed from the air suction port 32 toward the air discharge port 33 (see FIG. 3), so that the inside of the rice grain collecting hopper 38 becomes a negative pressure, and the opening and closing cover 39 is sucked. As a result, the rice grain outlet 48 is closed (see the position indicated by the two-dot chain line indicated by the reference numeral 39 in FIG. 3). If the suction device 35 continues to be operated in this state, the rice grains in the container 41 are sucked from the suction nozzle 42 and are then fried.

  In the container 41, since the rice grains are compressed and densely packed, no air layer is formed. However, if the suction nozzle 42 provided with the air storage chamber 65 shown in FIG. 6 is inserted into the container 41, the air in the air storage chamber 64 is sucked into the suction passage 63, and the suction wind is generated, and together with the suction wind, The rice grains can be fried (see FIG. 7).

  The rice grains sucked from the suction nozzle 42 flow into the rice grain separation passage 36 via the suction hose 43 and the insertion port 44. The rice grains flowing into the rice grain separation passage 36 are swirled through the rice grain swirling passage 37 to be separated into solid and air, and the rice grains settle and accumulate in the rice grain collection hopper 38.

  The driving time of the suction device 35 is controlled by the timer circuit 57 so as to be driven for a predetermined time (about 25 seconds) (S4 in FIG. 5). Therefore, the accumulated amount in the rice grain collecting hopper 38 is L3 ( It is deposited up to the position indicated by the two-dot chain line in FIG. Next, the driving of the suction device 35 is stopped for a predetermined time (about 10 seconds) (S5 in FIG. 5). At this time, since the negative pressure in the rice grain collecting hopper 38 is released, the opening / closing lid 39 is rotated downward by its own weight, and the rice grain discharge port 48 is opened (the position indicated by the solid line 39 in FIG. 3). reference). As a result, the rice grains flow out of the rice grain collection hopper 38 and are supplied to the next temporary storage hopper 8 (the amount of accumulation is L2 (two-dot chain line in FIG. 3)).

  When the accumulated amount of rice grains reaches the position L2, the rice milling machine main body 6 is in operation, and the accumulated amount gradually decreases from the position L2 to the position L1 (see FIG. 3). Then, whether or not rice grains are accumulated in the temporary storage hopper 8 is checked again by the photo sensor 49 (S6 in FIG. 5). If the accumulated amount is at the position L1, the photosensor 49 determines that there is no rice grain, and considers that the first frying operation (one frying amount is 10 kg of raw brown rice) is completed. , To the step 7 in FIG. 5 (S7 in FIG. 5). Here, the count is incremented, and then it is determined whether the count value is 3 or more (S8 in FIG. 5). If the count value is less than 3, the process returns to step S4 of FIG. 5 so as to perform the second and subsequent frying operations. If the count value is 3 or more, it is considered that the 30 kg of raw brown rice in the container (rice bag for 30 kg) 41 has been completely fried and the operation is completed.

  If it is determined in step S6 in FIG. 5 that the accumulated amount remains at the position of L2 and the photosensor 49 also has rice grains, the presence or absence of the rice grains is checked again by the photosensor 49 after a while (see FIG. 5). Step S9). Also in step S9, if it is determined that there is a rice grain, the presence or absence of the rice grain is further confirmed by the photo sensor 49 after a while (step S10). If it is still determined that there are rice grains, the process is terminated because there is a possibility of a malfunction such as the rice milling machine main body 6 being stopped.

  If the operator presses the manual button 54 of the suction-type fryer 9, it is determined which button has been pressed (S1 in FIG. 5), and if it is confirmed that the manual button 54 has been pressed (FIG. 5). 5 S11), it is confirmed by the photo sensor 49 whether or not rice grains are accumulated in the temporary storage hopper 8 (S12 in FIG. 5). When it is confirmed that no rice grains accumulate on the photosensor 49, the suction device 35 is driven (S13 in FIG. 5). The driving time of the suction device 35 is controlled by the timer circuit 57 to be driven for a predetermined time (about 30 seconds), and it is determined whether or not the predetermined time has elapsed (S14 in FIG. 5). If a predetermined time has elapsed, it is determined that the frying operation has been completed, and the suction device 35 is stopped (S15 in FIG. 5), and the process ends.

  As described above, according to the present embodiment, the rice polishing machine main body 6 is mounted on the gantry 5 and the temporary storage hopper 8 for temporarily storing the raw brown rice is provided above the rice polishing machine main body 6. The upper part of the hopper 8 is provided with a suction type frying machine 9 capable of directly sucking the raw brown rice from the container 41 filled with the raw brown rice and frying the raw brown rice to the temporary storage hopper 8, so that the raw brown rice is packed. The raw brown rice is sucked directly from the container 41 and the raw brown rice to be supplied to the rice milling machine body 6 is temporarily stored in the temporary storage hopper 8 for temporarily storing the raw brown rice. Therefore, the raw brown rice packed in the container 41 is supplied to the supply hopper. The work of stuffing is no longer necessary, and the work of stuffing the brown rice and the discharge of the polished rice is not required at all times. Further, after finishing the rice polishing operation, there is also an advantage that the raw brown rice scattered on the floor surface of a work place such as a barn can be sucked and the floor surface can be cleaned.
