The rice cooker 4 containing a predetermined amount of rice and water is conveyed by the conveying means 6 to a rice cooking device (not shown).

  The rice washing apparatus 1 includes a rice washing apparatus main body 11 that performs washing with water pressure at the time of rice washing, and a rice feeding pipe that sends the rice after washing from the rice washing apparatus main body 11 to the filling machine 2 together with water (water for washing the rice) at the time of rice feeding. 12 and a return pipe (overflow pipe) 13 for returning water from the filling machine 2 toward the rice washing apparatus main body 11 at the time of rice feeding.

  The rice washing apparatus main body 11 has a water supply tank 16 which is an outer tank and a rice washing tank 17 disposed in the water supply tank 16. The rice washing tank 17 is formed with a large number of holes through which only the water does not pass but the water contacts the inside of the water supply tank 16.

  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 cleansing water (water for cleaning the rice) when washing the rice, and clean water is supplied as cleaning water (cleaning water in the tube) when cleaning the pipe. The The washing water is warm water that has been heated to make it easier to remove dirt, for example, at a temperature of 40 degrees or more. The washing water may contain a detergent and be effective for removing deposits such as soot. In addition, although not shown, a drain outlet through which an overflow pipe can be inserted is provided at the bottom of the water supply tank 16.

  The rice feeding pipe 12 is provided from the rice washing apparatus main body 11 to the filling machine 2. The upstream end of the rice feeding pipe 12 (the end on the side of the rice washing apparatus main body 11) is connected to the bottom of the rice washing tank 17 of the rice washing apparatus main body 11. Connected to the upstream end is a discharge side of a pump 21 that is a pumping means for sucking and discharging the water (washed rice water, wash water) in the water supply tank 16 to a high pressure. A diffuser for sucking the rice in the rice washing tank 17 is provided in the upstream end portion.

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

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

  As shown in FIG. 1, the inner peripheral surfaces of the rice transmission pipe 12 and the return pipe 13 are washed at the time of washing the inside of the rice transmission pipe 12 and the return pipe 13 with washing water (at the time of washing in the pipe). A filter 26 that captures deposits (dirt) removed from the pipe is detachably attached to the downstream end of the return pipe 13.

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

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

  And the 1st horizontal pipe member 31 which comprises the upstream edge part of the return pipe 13 is drained so that the water in the predetermined height position in the side surface of the immersion tank 3 of the filling machine 2, ie, the immersion tank 3, may not overflow. It is fixed in a position where it can. A replenishing port 29 for replenishing 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 uses the washing water to wash the inside of the rice sending pipe 12 and the inside of the return pipe 13 (at the time of washing in the pipe). 3 is provided with a connecting pipe 41 that is detachably connected between the rice sending pipe 12 and the return pipe 13 without flowing into the pipe 3. That is, for example, the rice washing apparatus 1 is connected between the rice sending pipe 12 and the return pipe 13 during washing in the pipe, but is connected to the unit-like connecting pipe 41 that is removed from between the rice sending pipe 12 and the return pipe 13 during rice feeding. have.

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

  Note that the inner diameter of the return pipe 13 is larger than the inner diameter of the rice transmission pipe 12. That is, for example, the return pipe 13 does not return only the rice washing water sent together with the rice into the immersion tank 3 by the rice transmission pipe 12 at the time of rice transmission, but from the water supply pipe (not shown) into the immersion 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, so that the amount of drainage from the immersing tank 3 is allowed.

  For this reason, 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 positioned along the horizontal direction) where the water returning to the rice washing apparatus main body 11 does not touch during rice feeding. In particular, dirt is likely to adhere to the portion, and when it is repeated, it becomes sticky and a lump is easily generated.

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

  First, as shown in FIG. 2, the operator removes the connecting pipe 41 and the filter 26 when washing the rice. In addition, the operator switches the switching lever portion 22 of the direction switching valve 23 to the rice washing position (the position of the two-dot chain 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 rice before washing is supplied into the rice washing 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, the rice washing with the water pressure of the washing water is performed in the rice washing tank 17 of the hydraulic rice washing apparatus main body 11.

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

  Then, the rice after the washing is supplied together with water into the soaking tank 3 of the filling machine 2 through the rice sending pipe 12 and soaked in the soaking 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 immersion tank 3 by the rice transmission pipe 12, the amount of water in the immersion tank 3 increases, so that the increased amount passes through the return pipe 13 which is an overflow pipe. Then, the water is returned to the water tank 16 of the rice washing device main body 11.

  Thus, the water circulates through the rice transmission pipe 12 and the return pipe 13, and the rice is sent by the circulating water. And when all the rice in the rice washing tank 17 is exhausted and rice feeding is completed, the pump 21 is stopped and the circulation of water is stopped.

  Here, when the rice washing apparatus 1 is repeatedly used as described above, deposits (dirt) such as rice cakes adhere to the inner peripheral surface of the rice sending pipe 12 and the inner peripheral surface of the return pipe 13. Furthermore, there is also a risk that the dirt that has been stuck to the tube due to repeated adhesion and suddenly peels off and is mixed with the rice into the next process. For this reason, in order to remove the deposits adhering in the respective pipes of the rice transmission pipe 12 and the return pipe 13, it is necessary to perform in-pipe cleaning for cleaning the inside of the rice transmission pipe 12 and the return pipe 13.

  At the time of in-pipe cleaning, as shown in FIG. 1, the operator connects the connection pipe 41 in a sealed state between the downstream end of the rice transmission pipe 12 and the upstream end of the return pipe 13 and returns the filter 26. Attach to the downstream end of the 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 cleaning water (for example, warm water) is supplied into the water supply tank 16, when the pump 21 is operated, the cleaning water does not flow into the immersion tank 3 of the filling machine 2 and is sent to the rice. The pipe 12 circulates through the pipe 12, the connection pipe 41, and the return pipe 13, and the circulating washing water performs in-pipe washing for both the rice sending pipe 12 and the return pipe 13.

  At this time, the operator operates the operating portion 27 of the ball valve 28 to adjust the opening, thereby discharging the air remaining in the return pipe 13. That is, the air in the return pipe 13 is vented by adjusting the opening of the ball valve 28 in the open state to increase the washing water pressure in the return pipe 13 that is larger than the inner diameter of the rice transmission pipe 12.

  Next, when the pipe cleaning by circulation of the 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 washing water stops, and the washing water is at least accumulated in the return pipe 13.

  At this time, when air remains in the return pipe 13 (for example, when the operator has not vented air or when the air has not been sufficiently vented), the worker must open the opening / closing lid 30. The replenishment port 29 is opened after being removed, and cleaning water is replenished into the return pipe 13 from the replenishment port 29 to fill the return pipe 13 with water.

  Then, the adhering matter that adheres to the inner peripheral surface of the return pipe 13 and is particularly clumped is peeled off from the inner peripheral surface of the return pipe 13 by being immersed in the fully-washed cleaning water in the return pipe 13 for a predetermined time. Removed.

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

  At the time of cleaning in the pipe by circulating the cleaning water and immersing in the cleaning water, the deposits removed from the inside of the rice sending pipe 12 and the return pipe 13 are filtered by the filter 26 attached to the downstream end of the return pipe 13. 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 when washing the inside of the rice sending pipe 12 and the return pipe 13 using washing water, It is sufficient, and it is not necessary to frequently remove the rice transmission pipe 12 and the return pipe 13 as in the conventional case, and the pipe can be easily cleaned.

  Moreover, since the washing water does not flow into the filling machine 2 which is the next process apparatus, it is possible to prevent the deposits removed from the pipe from entering the rice cooker 4 through the filling machine 2.

  In addition, the ball valve 28 is set to an open state when the pipe is cleaned by circulation of the washing water and is set to a closed state when the pipe is washed by being immersed in the washing water. In-pipe cleaning by dipping can properly perform in-pipe cleaning on the rice transmission pipe 12 and the return pipe 13.

  In particular, for the return pipe 13 where deposits are likely to adhere, the cleaning water can penetrate into the deposits by immersing the deposits in the cleaning water, and the deposits can be effectively removed. Can be reduced.

  Further, since the filter 26 is detachably attached to the downstream end portion of the return pipe 13 during washing in the pipe, the deposit removed from the pipe can be captured by the filter 26, and the deposit enters the rice washing apparatus main body 11. Can be prevented.

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

  In the above embodiment, the configuration in which the connection pipe 41 is connected in a sealed state has been described. However, the present invention is not limited to this. For example, as shown in FIGS. 3 and 4, washing water flows into the filling machine 2. The connection pipe 41 may be connected in a non-sealed state to the extent that the cleaning water can be guided so as not to flow.

  In the rice washing apparatus 1 shown in FIGS. 3 and 4, the downstream end portion of the rice feeding pipe 12 is located in the upper part in the rice water separation unit 51 of the filling machine 2. The rice water separation unit 51 has a downwardly inclined rotating cylindrical body 52 having a net-like cylindrical shape, and rice and water are rotated from the rice feed pipe 12 into the rotating cylindrical body 52 during rotation. When supplied from the upper opening surface of the body 52, the rice is discharged from the lower opening surface of the rotating cylindrical body 52 and falls into the immersion tank 3, and water is collected without flowing into the immersion tank 3. Then, it is fed into the return pipe 13. The rotating cylindrical body 52 can be attached to and detached from a support body (not shown) that supports the rotating cylindrical body 52.

  Further, an opening 55 is formed in the upper part of the first horizontal pipe member 31 of the return pipe 13, and a trough for returning the water sent together with the rice by the rice sending pipe 12 to the return pipe 13. A lower end portion of the guide tube member 56 having a conical cylindrical shape is connected. The first horizontal pipe member 31 and the guide pipe member 56 constitute an upstream end portion of the return pipe 13.

  As shown in FIG. 3, when cleaning the inside of the pipe, after removing the rotating cylindrical 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 By inserting the downstream end portion into the guide tube member 56 of the return pipe 13 so as to be detachable, the connecting pipe 41 is connected between the downstream end portion of the rice sending pipe 12 and the upstream end portion of the return pipe 13. . Further, a cap (opening / closing lid) 57 for cleaning is detachably attached to the upstream end portion (overflow inlet portion) of the first horizontal tube member 31 of the return pipe 13.

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

  Further, in any of the above embodiments, the rice washing apparatus main body 11 has been described with respect to the hydraulic type in which the rice washing is performed by the water pressure of the rice washing water from the rice washing pipe 24, for example, the screw type in which the rice washing is performed by the rotation of the rice washing blades. Even if it is etc., what is necessary is just the rice washing apparatus main body via the return pipe | tube which returns the water from the rice-feeding pipe | tube which sends rice with water toward a filling machine, and a filling machine.

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

  In addition, for example, the washing water may be stored in both the rice transmission pipe 12 and the return pipe 13 at the time of washing in the pipe by immersion in washing water.

  Further, the connecting 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. A replenishing port for replenishing the cleaning water may be provided in the connection pipe 41.

  In the above embodiment, it is only described that both pipes are washed by circulating and immersing washing water in the rice sending pipe and the return pipe, but the rice washing tank of the rice washing apparatus main body is also washed at the same time. Of course.
