  In addition, a discharge cover 22 for guiding the white rice and water discharged from the discharge port 11a to the dewatering unit is disposed at the lower portion of the rice washing cylinder unit 11.

  As shown in FIGS. 5 to 7, the pouring / dehydrating unit 30 is disposed below the rice washing unit 10, and also includes a white rice supply pipe 31 and a white rice supply pipe 31 disposed below the discharge port 11 a of the rice washing cylinder unit 11. A dewatering screw 32 having a cylindrical wall portion 32a disposed in the vertical direction and two blade portions 32b disposed around the wall portion 32a, and a tubular shape disposed around the dewatering screw 32 A dehydrated basket 33, a white rice passage 35 disposed around the dehydrated basket 33 and dropping the white rice conveyed by the dehydration screw 32, a white rice scraping portion 36 disposed below the white rice passage 35, and a white rice scraping portion 36, and a drive unit 40 that drives the dewatering screw 32, the dehydrated basket 33, and the white rice raking unit 36.

  The dehydrating screw 32 forms the wall portion 32a in a net shape, thereby pouring fresh water supplied from a fresh water supply pipe 37 piped from above into the wall portion 32a onto the blade portion 32b through the net-like wall portion 32a. In addition, the white rice fed on the two blade portions 32b can be fed from below to above. A dewatering screw plate 38 that closes the cylindrical interior of the dewatering screw 32 is disposed below the dewatering screw 32 to receive the white rice dropped from the white rice supply pipe 31 and from the top of the dewatering screw plate 38, two blade portions 32b. Move white rice up. Further, the dehydrating screw plate 38 is connected to a screw drive shaft 42 extending from the driving unit 40, and is thereby disposed so as to be rotatable with the dehydrating screw 32 in the axial direction. In addition, the net part of the wall part 32a is formed with the hole diameter of the grade which does not let white rice pass even if it lets fresh water pass.

  The dewatering basket 33 includes a net-like inner wall portion 33a arranged so as to surround the outer peripheral surface of the blade portion 32b of the dehydrating screw 32, and a plurality of drainage blade portions 33b arranged radially around the inner wall portion 33a with respect to the axis. The fresh water poured into the dehydration screw 32 and the water blown off by the rotation of the white rice are sent to the drain outlet. In addition, a gap is formed between the inner peripheral surface of the inner wall portion 33a of the dewatering basket 33 and the outer peripheral surface of the dewatering screw blade portion 32b so that white rice does not pass through the net portion of the inner wall portion 33a. Is also formed with a pore size that does not allow white rice to pass through.

  The white rice passage 35 is formed in a drum shape by forming a passage 35c between the inner ring 35a and the outer ring 35b formed over the entire circumference so as to be connected to the white rice scraping portion 36 from the upper part of the dehydrating screw 32. The space between the white rice scraping portion 36 is open.

A plurality of scraper scrapers 36c are arranged radially between the inner ring 36a and the outer ring 36b, and are fixed to a scraper support plate 39 connected to a scraper drive shaft 54 described later. A discharge port 34c for discharging the white rice and a chute 34a connected to the discharge port 34c are disposed in a part of the white rice scraping portion 36, and the fresh water is drained from the drain pipe 34b.

  As shown in FIG. 7, the drive unit 40 rotates and drives the gear case 41 supported by the main body case 1 (see FIG. 1) below the dewatering screw 32, the dewatering screw 32, the dewatering basket 33, and the scraping scraper 36c. It has a gear set and two drive motors.

  The main drive motor 43 has a first gear 45 fixed to a connection shaft 44 connected to the output shaft 43a via a key member, and a second gear fixed to the screw drive shaft 42 connected to the dehydrating screw 32 with a key. Thus, the rotational output from the drive motor 43 is transmitted to the dehydrating screw 32 via the screw drive shaft 42.

  Around the screw drive shaft 42, a dewatering car drive shaft 47 is connected to a connecting plate 50 fixed to the inner wall 33a of the dewatering car 33 and the lower end of the drainage blade 33b, and is concentric with the drive shaft 42. Is arranged. A third gear 48 is disposed above the first gear 45 via a key member on the connecting shaft 44 connected to the output shaft 43a of the main drive motor 42, and the dewatering basket drive shaft 47 via the key member. It is in mesh with the arranged fourth gear 49. As a result, the rotational output of the main drive motor 43 is transmitted to the dewatering car 33 via the dewatering car drive shaft 47. A collar 51 that supports inner rings of bearings disposed at both upper and lower ends of the dewatering car drive shaft 47 is interposed around the dewatering car drive shaft 47.

  By changing the number of teeth of the first gear 45 and the third gear 48, the gear ratio that meshes from the first gear 45 to the second gear 46, and the teeth from the third gear 48 to the fourth gear 49. If the gear ratio to be combined is different, the rotation of the dehydrating screw 32 can be made faster than the rotation of the dehydrating basket 33, and the centrifugal force can be increased to improve the drainage of water due to dehydration.

  Around the dewatering car drive shaft 47, a bearing case 53 holding a bearing is disposed so as to be rotatable with respect to the dewatering car drive shaft 47. Further, around the bearing case 53, a scraper drive shaft 54 is attached to the bearing case 53. It is arranged so that it can rotate freely.

  On the other hand, a sub drive motor 55 is disposed at one end of the gear box 41, and is connected to a fifth gear 56 connected to the output shaft 55a of the sub drive motor 55 by a key member and to the scraper drive shaft 54 by a key member. The sixth gear 57 and the sixth gear 57 are in mesh with each other, whereby the rotation output of the sub drive motor 55 is transmitted to the scraping scraper 36c.

  Accordingly, the main drive motor 53 rotates the dehydrating screw 32 and the dehydrating basket 33, and the sub drive motor 55 rotates the scraping scraper 36c.

  The drying unit 60 is disposed below the main body case 1, and is disposed below the chute 34 a connected to the discharge port of the pouring / dehydrating unit 30 (not shown) and below the rice washing unit 10. A rotary table 61 that receives the discharged white rice, and a heater 62 that is arranged in the main body case 1 and applies hot air to the white rice on the rotary table 61 are provided. The rotary table 61 is rotationally driven by a motor 63, and the heater 62 is disposed above the rotary table 61.

  Next, the operation of the washing-free rice manufacturing apparatus M configured as described above will be described.

  When the white rice is supplied from the supply hopper 5, the supplied white rice is conveyed to the supply pipe 7 while being stirred by the screw feeder 6, and the white rice conveyed to the supply pipe 7 falls in the supply pipe 7 and is washed in the rice washing section. 10 is supplied.

  Before the white rice is supplied to the rice washing unit 10, fresh water is supplied from the water supply port 15, and the discharge port 11a is blocked by the valve portion 14c of the pressure regulating valve 14, thereby filling the inside of the rice washing cylinder unit 11 with fresh water. ing. And while new fresh water is hydrated, fresh water continues draining from the drain port 11c. When white rice is supplied from the white rice supply section 3 into the fully washed rice cylinder section 11, the white rice is difficult to enter into the washed rice cylinder section 11, but is always drained from the drain port 11c. From the supply unit 3, the rice-washing cylinder unit 11 sequentially enters.

  Since the rice washing screw 12 is rotated in one direction by the motor 13 in the rice washing cylinder portion 11, the white rice is conveyed toward the discharge port 11 a by the blade portion 12 b of the rice washing screw 12. At this time, in the state where water is added in the rice-washing cylinder portion 11, white rice accumulated in the blade portion 12 b of the rice-washing screw 12 rotates together with the blade portion 12 b and becomes clogged. The stirring pin 21 that protrudes from the inner peripheral surface stirs the clogged white rice, so that the white rice is conveyed toward the discharge port 11 a while being stirred in the rice washing cylinder portion 11 by the rotation of the rice washing screw 12. As a result, the white rice is washed.

  In addition, since the conveyed white rice presses the pressure regulating plate 14a of the pressure regulating valve 14 against the urging force of the coil spring 14d, the degree of stagnation between the white rice is adjusted by adjusting the pressure of the coil spring 14d. It will be. For example, in the case of Koshihikari made in Niigata, since the sticking of the wrinkles is relatively small, the urging force of the coil spring 14d is reduced to reduce the pressure of the stagnation. On the contrary, in the case of Kirara produced in Hokkaido, the urging force of the coil spring 14d is increased to increase the pressure of the stagnation.

  The white rice discharged from the discharge port 14 a of the rice washing unit 10 is poured through the white rice supply pipe 31 and supplied to the dewatering unit 30.

  The white rice that has passed through the white rice supply pipe 31 passes through the dehydration screw 32 and falls onto the dehydration screw plate 38. Since the dehydrating screw plate 38 is rotationally driven by the main drive motor 43 of the driving unit 40, the white rice on the dehydrating screw plate 38 moves on the blade portion 32b of the dehydrating screw 32 by centrifugal force. The white rice that has moved to the blade portion 32 b of the dehydrating screw 32 is sent upward by the rotation of the dehydrating screw 32.

  The dehydrating screw 32 is rotated by the main drive motor 43 via the first gear 45, the second gear 46, and the screw driving shaft 42, and the dewatering basket 33 is rotated by the main driving shaft 43 to the third gear 48 and the second gear. 4 is rotated through a gear 49 and a dewatering basket drive shaft 47. By setting the number of teeth of the first gear 45 to be larger than the number of teeth of the third gear 48, the gear ratio for rotating the dewatering screw 32 and the dewatering basket 33 is made different so that the dewatering screw 32 is dewatered. I try to rotate faster.

  While the white rice rises on the spirally formed dewatering screw blade 32b by the rotation of the dewatering screw 32 and is conveyed from the lower end portion to the upper end portion of the dewatering screw 32, fresh water is supplied to the fresh water supply pipe. It is poured from the inside of the dehydrating screw 32 into the white rice that is fed from the inside of the dewatering screw 32 and conveyed.

  The fresh water poured into the white rice is discharged to the outside of the dehydrated basket 33 through the net portion of the inner wall 33a of the dehydrated basket 33. The water discharged to the outside is drained from the drain pipe 34b by the wind pressure generated in the dewatering basket 33 by the rotation of the drain blade 33b. Then, the water is drained from the drain pipe 34b to the outside of the pouring / dehydrating unit 30. On the other hand, the white rice is further washed by supplying fresh water after removing rice cakes, dust and the like adhering in the washing unit 10. As described above, since the dewatering screw 32 rotates faster than the dewatering basket 33, the water adhering to the white rice is blown off by the centrifugal force of the dewatering screw 32, and the net of the inner wall portion 33a of the dewatering basket 33 is again. It goes out of the dehydration basket 33 through the section. Then, the water discharged to the outside is transported to the drain pipe 34b by the drainage blade section 33b and drained from the drain pipe 34b to the outside of the pouring / dehydrating section 30.

  When the drained white rice reaches the upper end of the dewatering screw 32, it enters into the white rice passage 35 from the dehydrating screw 32 by the centrifugal force generated by the rotation of the dewatering screw 32 and the dewatering basket 33 and is supplied into the white rice scraping portion 36. It becomes.

  In the white rice scraping portion 36, the scraping scraper 36 c is rotationally driven by the auxiliary drive motor 55 via the fifth gear 56, the sixth gear 57, and the scraper drive shaft 54. Therefore, the white rice supplied to the white rice scraping unit 36 is transported to the discharge port by the scraping scraper 36c, and is transported from the discharge port to the drying unit 60 through the chute 34a.

  A rotating table 61 is gently rotated by the motor 63 on the drying unit 60, and air warmed from the heater 62 is blown onto the rotating table 61 as warm air. Accordingly, the white rice that has flowed onto the rotary table 61 through the chute 34a is dried while rotating on the rotary table 61, and when the dried white rice is discharged from the discharge port, the rice is washed without washing. It will be packed in a bag.

  As described above, the washing-free rice manufacturing apparatus M according to the embodiment arranges the rice washing screw 12 arranged in the rice washing unit 10 so as to be inclined downward with respect to the horizontal direction, and discharges the tip of the rice washing cylinder unit 11. Since the upper end of the pouring / dehydrating unit 30 is arranged below 11a and the drying unit 60 is arranged below the pouring / dehydrating unit 30, the entire area of the apparatus M is lengthened in the vertical direction. Is made smaller. Therefore, a compact washing-free rice production apparatus can be provided.

  Moreover, since the pressure regulating valve 14 is arrange | positioned at the front-end | tip of the rice-washing cylinder part 11 in the rice-washing part 10, and it is comprised so that the pressure of the kneading condition of the white rice to be supplied can be adjusted, it is the production area, a kind, It is possible to adjust the degree of washed rice (turbidity accuracy) depending on the production year.

  In addition, in the pouring / dehydrating unit 30, white rice that has been subjected to water washing and scum washing by the rice washing unit 10 is further poured and washed to improve the washing degree of non-washed rice so that it can meet the revised turbidity standard. Yes.

  Further, the dehydration screw 32 and the dehydration basket 33 are driven by the main drive motor 43, and the dehydration screw 32 is driven faster than the dehydration basket 33, thereby improving drainage from white rice and improving the dehydration capacity. can do. In addition, since the drive unit 40 of the pouring / dehydrating unit 30 is configured by a gear set surrounded by a gear case 41, it can be configured compactly. In addition, since the belts that have been used in the past can be abolished, durability can be improved and maintenance such as belt replacement can be eliminated without causing drive transmission failure due to belt extension or damage to the drive shaft due to the belt. it can.

  In addition, the dehydrating apparatus in the non-washed granular grain production apparatus of the present invention is not limited to the above-described form. For example, the non-washed granular material is a granular grain other than rice as described in the field of the invention. Also good.
