  The rice washing device 1 includes a rice washing device body 11 that performs water washing by water pressure when washing rice, and a rice sending pipe that sends the rice after washing rice together with water (water for washing rice) from the rice washing device body 11 to the filling machine 2 when sending rice. It is provided with 12 and a return pipe (overflow pipe) 13 for returning water from the filling machine 2 toward the rice washing device body 11 at the time of sending rice.

  The rice washing apparatus body 11 has a water supply tank 16 which is an outer tank, and a rice washing tank 17 arranged in the water supply tank 16. The rice washing tank 17 has a large number of holes through which water does not pass and only water passes, which is formed on the surface in contact with the inside of the water supply tank 16.

  Then, the rice before washing is supplied into the rice washing tank 17 from a rice storage (not shown). Further, in the water supply tank 16, clean water is supplied as washing water (water for washing rice) when washing rice, and as washing water (water for washing inside pipe) when washing the inside of the pipe. It The cleaning water is warm water, for example, heated to a temperature of 40 ° C. or higher so as to easily remove dirt. The cleaning water may contain a detergent and be effective for removing adhered matters such as bran. Further, at the bottom of the water supply tank 16, although not shown, a drain port into which an overflow pipe can be inserted is provided.

  The rice sending pipe 12 is provided from the rice washing device body 11 to the filling machine 2. The upstream end of the rice transfer pipe 12 (the end on the side of the rice-washing device body 11) is connected to the bottom of the rice-washing tank 17 of the rice-washing device body 11. A discharge side of a pump 21, which is a pumping means for sucking the water (washing water, washing water) in the water supply tank 16 into a high pressure and discharging the water, is connected to the upstream end portion. A diffuser for sucking the rice in the rice washing tank 17 is provided in the upstream end.

  The downstream end (end on the filling machine 2 side) of the rice transfer pipe 12 is located in the upper portion of the dipping tank 3 of the filling machine 2. A rice washing pipe 24 is connected to an intermediate portion of the rice feeding pipe 12 via a direction switching valve 23 having a switching lever portion 22, and a downstream end of the rice washing pipe 24 is located above the rice washing tank 17. There is.

  The return pipe 13 is provided from the filling machine 2 to the rice washing device body 11. The upstream end of the return pipe 13 (the end on the filling machine 2 side) is located in the upper part of the dipping tank 3 of the filling machine 2. The downstream end of the return pipe 13 (the end on the side of the rice-washing device body 11) is located in the upper part of the water supply tank 16 of the rice-washing device body 11.

  Then, as shown in FIG. 1, when cleaning the inside of the rice sending pipe 12 and the inside of the return pipe 13 by using washing water (when cleaning inside the pipe), each inner peripheral surface of the rice sending pipe 12 and the return pipe 13 A filter (26) for capturing the adhered matter (dirt) removed from the return pipe (13) is detachably attached to the downstream end of the return pipe (13).

  A ball valve 28, which is a valve for adjusting the flow rate, is provided in the middle of the return pipe 13, that is, in the vicinity of, for example, the downstream end, which has an operating portion 27 that is rotated by an operator. That is, a ball valve 28, which is a flow rate adjusting valve manually operated by an operator, is provided on the downstream end side of the return pipe 13.

  Here, the return pipe 13 is located in order from the filling machine 2 toward the rice washing machine body 11, and has a first horizontal pipe member 31, a first vertical pipe member 32, a second horizontal pipe member 33, and a second vertical pipe member 34. The ball valve 28 is provided at the lower end side of the second vertical pipe member 34.

  Then, the first horizontal pipe member 31 forming the upstream end of the return pipe 13 is discharged at a predetermined height position on the side surface of the immersion tank 3 of the filling machine 2, that is, so that the water in the immersion tank 3 does not overflow. It is fixed in a position that allows it. Further, a replenishing port 29 for replenishing the cleaning water is formed at the upper end of the first vertical pipe member 32, and the replenishing port 29 is closed by an opening / closing lid 30 so as to be opened and closed.

  Further, as shown in FIG. 1, the rice washing apparatus 1 is a dipping tank of the filling machine 2 for the washing water at the time of washing for washing the inside of the rice sending pipe 12 and the inside of the return pipe 13 with the washing water (when washing inside the pipe). A connection pipe 41 is detachably connected between the rice sending pipe 12 and the return pipe 13 without flowing out into the inside 3. That is, for example, the rice washing apparatus 1 is connected between the rice sending pipe 12 and the return pipe 13 at the time of washing the inside of the pipe, but is disconnected from the rice sending pipe 12 and the return pipe 13 at the time of sending the rice. have.

  The connecting pipe 41 is composed of, for example, a single L-shaped tubular member, the upstream end of which is detachably connected to the downstream end of the rice sending pipe 12, and the downstream end of which is the return pipe 13. It is detachably connected to the upstream end. That is, the connecting pipe 41 is connected to the rice sending pipe 12 and the return pipe 13 in a sealed state so that the washing water does not leak from the connecting portion.

  The inner diameter of the return pipe 13 is larger than the inner diameter of the rice transport pipe 12. That is, for example, the return pipe 13 does not return only the washing water sent together with the rice into the dipping tank 3 by the rice sending pipe 12 at the time of sending the rice, but from the water supply pipe (not shown) into the dipping tank 3. Since the supplied water is also returned, the inner diameter of the return pipe 13 is made larger than the inner diameter of the rice feeding pipe 12 to allow a sufficient amount of drainage from the immersion tank 3.

  Therefore, on the inner peripheral surface of the return pipe 13, there is a portion (for example, the upper portion of the inner peripheral surface of the horizontal pipe members 31 and 33 located along the horizontal direction) that the water returning to the rice washing apparatus body 11 does not touch when sending rice. In particular, stains are likely to adhere to that portion, and repeated repetitions tend to cause sticking and solidification.

  Next, the operation and the like of the rice washing apparatus 1 will be described.

  First, when washing rice, as shown in FIG. 2, the operator removes the connecting pipe 41 and the filter 26. Further, the operator switches the switching lever portion 22 of the direction switching valve 23 to the rice washing position (the position indicated by the chain double-dashed line in FIG. 2) and operates the operation portion 27 to set the ball valve 28 to the open state. deep.

  Then, after a predetermined amount of water is supplied into the water supply tank 16 and a predetermined amount (for example, 7 kg) of unwashed rice is supplied into the rice wash tank 17, the pump 21 is operated.

  Then, the rice and water circulate through the rice sending pipe 12 and the rice washing pipe 24, and as a result, rice is washed by the water pressure of the washing water in the rice washing tank 17 of the hydraulic type rice washing apparatus body 11.

  Then, when the rice washing is completed and the rice after the rice washing is sent to the next process, the operator switches the switching lever portion 22 of the direction switching valve 23 to the rice sending position (the position shown by the solid line in FIG. 2).

  Then, the washed rice is supplied together with water into the dipping tank 3 of the filling machine 2 through the rice feeding pipe 12, and is dipped in the dipping tank 3 for a predetermined time. The rice after soaking for a predetermined time is put into the rice cooker 4 by a predetermined amount by the measuring means 5.

  On the other hand, when rice and water are supplied into the dipping tank 3 by the rice sending pipe 12, the amount of the water in the dipping tank 3 increases. Through it, it is returned to the water supply tank 16 of the rice washing apparatus body 11.

  In this way, the water circulates through the inside of the rice sending pipe 12 and the inside of the return pipe 13, and rice is sent by this circulating water. Then, when all the rice in the rice washing tank 17 is exhausted and the rice transfer is completed, the pump 21 is stopped to stop the water circulation.

  Here, when the rice washing device 1 is repeatedly used as described above, deposits (dirt) such as bran adhere to the inner peripheral surface of the rice sending pipe 12 and the inner peripheral surface of the return pipe 13. Further, there is a risk that the dirt, which has been stuck to the inside of the tube due to repeated adhesion and solidified, is suddenly peeled off and mixed with the rice into the next step. For this reason, in order to remove the deposits adhering to the insides of the rice sending pipe 12 and the return pipe 13, it is necessary to perform in-pipe cleaning for cleaning the inside of the rice sending pipe 12 and the inside of the return pipe 13.

  At the time of cleaning the inside of the pipe, as shown in FIG. 1, the worker connects the connecting pipe 41 between the downstream end of the rice sending pipe 12 and the upstream end of the return pipe 13 in a sealed state, and returns the filter 26. Attached to the downstream end of tube 13. The switching lever portion 22 is set to the rice feeding position, and the ball valve 28 is set to the open state.

  Then, after a predetermined amount of washing water (for example, warm water) is supplied into the water supply tank 16, the pump 21 is operated, and the washing water does not flow into the immersion tank 3 of the filling machine 2 and the rice is sent. The washing water circulates through the pipe 12, the connection pipe 41, and the return pipe 13, and the circulating washing water performs the pipe washing for both the rice sending pipe 12 and the return pipe 13.

  At this time, the operator controls the opening degree by operating the operation portion 27 of the ball valve 28 to discharge the air staying in the return pipe 13. That is, the opening of the ball valve 28 in the open state is adjusted to increase the water pressure of the washing water in the return pipe 13 which is larger than the inner diameter of the rice feeding pipe 12, thereby bleeding the air in the return pipe 13.

  Next, when the pipe cleaning by circulating such cleaning water is completed, the operator stops the pump 21 and operates the operation unit 27 to switch the ball valve 28 from the open state to the closed state.

  Then, the circulation of the wash water is stopped and the wash water is at least accumulated in the return pipe 13.

  At this time, if air remains in the return pipe 13 (for example, if the operator did not bleed air, or if the air bleeding was insufficient), the operator should open the open / close lid 30. It is removed to open the refill port 29, and the return pipe 13 is replenished with wash water from the refill port 29 to fill the return pipe 13 with water.

  Then, the adhered matter that adheres to the inner peripheral surface of the return pipe 13 and sticks in particular as a clump is separated from the inner peripheral surface by being immersed in the fully filled washing water in the return pipe 13 for a predetermined time. To be removed.

  In this way, the inside cleaning (inside cleaning of the return pipe 13) is performed by immersing the deposits attached to the inner peripheral surface of the return pipe 13 in the cleaning water.

  In addition, during the cleaning of the inside of the pipe by circulating the cleaning water and immersion in the cleaning water, the deposits removed from the inside of the rice sending pipe 12 and the inside of the return pipe 13 are removed by the filter 26 attached to the downstream end of the return pipe 13. To be captured.

  Then, according to the rice washing apparatus 1, if the connecting pipe 41 is connected between the rice sending pipe 12 and the return pipe 13 at the time of washing the inside of the rice sending pipe 12 and the inside of the return pipe 13 using the washing water Since it is not necessary to frequently remove the rice sending pipe 12 and the return pipe 13 as in the conventional case, the inside of the pipe can be easily washed.

  Moreover, since the cleaning water does not flow into the filling machine 2 as the next process device, it is possible to prevent the deposits removed from the inside of the pipe from entering the rice cooker 4 via the filling machine 2.

  Further, since the ball valve 28 is set to the open state when cleaning the inside of the pipe by circulating the cleaning water and the closed state when cleaning the inside of the pipe by dipping in the cleaning water, the cleaning of the inside of the pipe and the cleaning water by circulating the cleaning water are performed. By cleaning the inside of the pipe by immersion, the inside of the rice sending pipe 12 and the return pipe 13 can be properly cleaned.

  In particular, for the return pipe 13 to which the adhered matter is likely to adhere, by immersing the adhered matter in the wash water, the wash water can penetrate into the adhered matter, the adhered matter can be effectively removed, and the amount of the wash water used Can be kept low.

  Further, since the filter 26 that is detachably attached to the downstream end of the return pipe 13 when cleaning the inside of the pipe is provided, the attached matter removed from the inside of the pipe can be captured by the filter 26, and the attached matter can be prevented from entering the rice washing apparatus body 11. It can be prevented.

  Further, since the return pipe 13 has a replenishment port 29 on the upstream end side for replenishing the wash water, the inside of the return pipe 13 can be filled with the wash water when washing the inside of the pipe by immersion in the wash water. Can be performed more appropriately.

  In addition, in the said one Embodiment, although the structure which connected the connection pipe 41 to the sealed state was demonstrated, it is not limited to this, For example, as shown in FIG.3 and FIG.4, flush water flows into the filling machine 2. As shown in FIG. The connection pipe 41 may be connected in a non-sealed state to the extent that the cleaning water can be guided so that it does not exist.

  In the rice washing apparatus 1 shown in FIGS. 3 and 4, the downstream end of the rice feeding pipe 12 is located in the upper portion of the rice water separating section 51 of the filling machine 2. The rice water separating unit 51 has a downwardly slanting rotary tubular body 52 having a net in a cylindrical shape, and the rice and water from the rice transport pipe 12 are rotated into the rotary tubular body 52 in the rotating rotary tubular body 52. When the rice is supplied from the upper opening surface of the body 52, the rice is discharged from the lower opening surface of the rotating tubular body 52 and drops into the immersion tank 3, and the water is collected without flowing into the immersion tank 3. And it is sent to the return pipe 13. The rotary tubular body 52 is attachable to and detachable from a support body (not shown) that supports the rotary tubular body 52.

  Further, an opening 55 is formed in the upper portion of the first horizontal pipe member 31 of the return pipe 13, and the opening 55 is provided for returning the water sent with the rice by the rice sending pipe 12 to the return pipe 13. The lower end portion of the guide tube member 56 having the shape of a truncated cone is connected. The first horizontal pipe member 31 and the guide pipe member 56 form an upstream end portion of the return pipe 13.

  Then, as shown in FIG. 3, when cleaning the inside of the pipe, after removing the rotary tubular body 52, the upstream end of the connecting pipe 41 is detachably connected to the downstream end of the rice sending pipe 12 and the connecting pipe 41 is removed. The downstream end is removably inserted into the guide pipe member 56 of the return pipe 13 to connect the connecting pipe 41 between the downstream end of the rice sending pipe 12 and the upstream end of the return pipe 13. . Further, a cap (opening / closing lid) 57 for cleaning is detachably attached to the upstream end portion (the inlet portion of the overflow) of the first horizontal pipe member 31 of the return pipe 13.

  Although not shown, for example, the downstream end of the connecting pipe 41 may be connected to the opening 55 of the first lateral pipe member 31.

  Further, in any of the above embodiments, the rice washing device body 11 has been described as a hydraulic type in which rice is washed by the water pressure of the washing water from the rice washing pipe 24. However, the main body of the rice washing device may be any one of the rice-washing device main body through the rice-feeding pipe for sending rice together with water to the filling machine and the return pipe for returning water from the filling machine.

  Further, the next process device (post-processing device) is not limited to the filling machine 2 and may be, for example, a draining conveyor device.

  Further, for example, when cleaning the inside of the pipe by immersion in the cleaning water, the cleaning water may be accumulated in both the rice sending pipe 12 and the return pipe 13.

  Furthermore, the connection pipe 41 may be made of, for example, a plurality of tubular members, or may be made of a flexible rubber pipe or the like. The connection pipe 41 may be provided with a replenishment port for replenishing the wash water.
