Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic rice washing apparatus, and more particularly to an automatic rice washing apparatus used in a one-pot rice cooking system that automatically cooks rice using a plurality of rice cooking pots conveyed on a line.
[0002]
[Prior art]
Conventionally, automated rice washing machines have been known as conventional rice washing machines. However, such rice washing machines are automatically cooked using a rice cooker that is sequentially transported on the line. Even if it is incorporated into the system, the time required for washing the rice is at the rate-determining stage of the system, and there is a disadvantage that efficient rice cooking cannot be performed. In order to eliminate this drawback, it is conceivable that the rice washing process is divided into a plurality of lines, and an automated rice washing machine is provided for each of them. However, the number of transfer lines is increased and the equipment becomes huge. In addition, there is a problem that the operation of returning the rice cooker to each original washing line from each rice washing line to the original conveying line is complicated and the control of the conveying apparatus becomes complicated.
[0003]
As for individual rice washing machines, conventional rice washing machines are mainly stirred rice washing machines that wash rice by rotating a stirring blade in a rice washing tank. In this stirring rice washing machine, Since the stirring blade is attached to the rotating shaft located in the center of the rice washing tank, the peripheral speed during rotation of the stirring blade is smaller in the vicinity of the center of the rice washing tank than in the periphery of the rice washing tank, and the rice located in the vicinity of the center of the rice washing tank However, there is a problem that it is difficult to wash the rice sufficiently. Therefore, if a plurality of such agitating type rice washing machines are installed in an automatic rice washing machine and each rice washing machine tries to wash the entire rice in the rice washing tank to a predetermined level, it uses more rice washing water than necessary. As a result, the amount of the washed rice polluted water increases, which is not preferable from the viewpoint of environment, and the washing time is unnecessarily long.
[0004]
[Problems to be solved by the invention]
The present invention has been made to solve the above-described problems of the prior art, and can efficiently supply washed rice in a rice cooker that is sequentially conveyed on the line. It is an object of the present invention to provide an automatic rice washing apparatus for a pot cooking rice system, and further to provide an automatic rice washing apparatus for a pot cooking rice system that requires a small amount of rice washing water.
[0005]
[Means for Solving the Problems]
As a result of intensive efforts to solve the above problems, the present inventors use a plurality of rice washer, organically link them with each other, and the washed rice discharged from each rice washer is By being guided to the pouring position to the rice cooker at a predetermined time interval, the washed rice can be sequentially and efficiently supplied into the rice cooker being conveyed on one conveyance line. The rice-washing machine used is a water-saving rice-washing machine that does not wash the entire horizontal cross-sectional area of the rice-washing tank as in the conventional rice-washing machine, but uses only the periphery of the rice-washing tank. As a result, the present invention was completed by finding that by using this machine, the rice washing efficiency of the automatic rice washing apparatus can be increased, the required rice washing water can be greatly reduced, and the washing time can be shortened.
[0006]
That is, the present invention provides a plurality of rice washers, a rice metering and supply device that measures and supplies a predetermined amount of rice to each of the plurality of rice washers, and supplies rice wash water to each of the plurality of rice washers. At least a rice-washing water supply device and a guide device for guiding the washed rice discharged from each of the plurality of rice-washing machines to a predetermined position; As is performed at intervals, each rice washing machine and / or an automatic rice washing apparatus for a pot cooking rice system having a control device for controlling the operation of each of the above-mentioned apparatuses, and a rice washing machine used in the automatic rice washing machine, Rotate the center axis of the rice washing tank in the space between the rice washing tank, the inner circumferential surface of the rice washing tank with a predetermined gap, and the outer circumferential surface of the core and the inner circumferential surface of the rice washing tank By using a rice washing machine having a stirring blade rotating as a shaft Te is intended to solve the foregoing problems.
[0007]
In the automatic rice washing apparatus for a single pot rice cooking system of the present invention, a guide device for guiding the washed rice discharged from a plurality of rice washing machines to a predetermined position is provided, and the predetermined position is provided. It is possible to incorporate a plurality of rice washing machines into one rice washing line because the rice is washed and guided to the rice at a predetermined time interval. Here, the predetermined position is the pouring position into the rice cooker, and usually the washed rice is finally dropped into the rice cooking pot by gravity, so when the washed rice is introduced The rice cooker should be under it.
[0008]
In order for the guide device to guide the washed rice to a predetermined position at a predetermined time interval, when the guide device includes an opening / closing valve, the opening / closing of the opening / closing valve is performed for a predetermined time. It may be controlled to be performed at intervals, or when the guide device is a simple passage connecting the rice discharge port of the rice washer to a predetermined position, the discharged rice after the washing of rice from the rice discharge port of the rice washer May be controlled to be performed at predetermined time intervals. Since the time when the washed rice is discharged from the rice discharge port of the rice washing machine is usually at the end of the rice washing process, the rice washing machine is controlled by controlling the start and / or end time of the rice washing process in each rice washing machine. It is also possible to discharge the washed rice from the rice outlet at a predetermined time interval. At this time, it goes without saying that the supply of rice and rice washing water to each rice washing machine is controlled in accordance with the start and / or end time of the rice washing process in each rice washing machine.
[0009]
In addition, the “predetermined time” in the “predetermined time interval” is a time longer than the time required to put the washed rice or rice water into the rice cooker, and usually one rice washer It is a time shorter than the time required from the start to the end of the rice washing performed by. The predetermined time interval is preferably a constant time interval, but is not necessarily constant. For example, a plurality of types of time required from the start to the end of rice washing differ due to different rice washing capacities. There may be a difference between long and short when using the rice washing machine. When using multiple rice washers that require the same time from the start to the end of rice washing, the time interval approximately equal to the time interval divided by the number of rice washers that use the time from the start to the end of rice washing It is preferable to set the time interval because the dead time is small and the automatic rice washing apparatus for a single pot rice cooking system of the present invention can be controlled at the same cycle all the time.
[0010]
In a preferred embodiment of the automatic rice washing apparatus for a pot of rice cooking system according to the present invention, the automatic rice washing apparatus includes a conveying device for loading / unloading the rice cooking pot at a lower portion of a predetermined position where the washed rice is guided by the guide device. Thus, it becomes possible to put the washed rice discharged from each rice washing machine into a rice cooker that is sequentially carried in and out. This conveying device that carries the rice cooker into and out of the lower portion of the predetermined position may be incorporated in the conveying line of the one-pot rice cooking system as a part of the conveying line of the entire system.
[0011]
It is desirable that the carry-in / carry-out of the rice cooker to the lower part of the predetermined position by the conveying device and the guidance of the washed rice to the predetermined position by the guide device are performed in synchronization with each other in synchronization. For this purpose, it is desirable to provide a control device for controlling the transport device. The control device for the conveying device may also serve as a control device that controls devices such as a rice washer and a rice metering and supplying device. When the transfer speed of the transfer device is set to be extremely slow, it is also possible to put rice into the rice cooker without stopping the transfer device, but normally when the rice cooker reaches the lower part of the predetermined position, It is desirable to temporarily stop the transfer device, add rice into the rice cooker, and if necessary, add rice cooking water, etc., and then operate the transfer device again to unload the rice cooker from the lower position. .
[0012]
In addition, when using a rice cooker and a rice washer of a normal size, it is sufficient to put the washed rice discharged from one rice washer into one rice cooker. You may make it throw in the rice cooker the rice after washing | cleaning from two or more rice washers. In that case, conveyance of the rice cooker is stopped until the end of the rice washing after the predetermined number of rice washers is completed, or the introduction of the rice cleaned after the predetermined number of rice washers is completed. It will be controlled to pass under a predetermined position over time.
[0013]
Further, the water-saving rice washing machine suitably used in the automatic rice washing apparatus for a single pot rice cooking system of the present invention has a core provided in the rice washing tank as described above, and the core of the rice washing tank is formed by the core. The surrounding area is occupied. Therefore, the introduced rice and water enter between the outer peripheral surface of the core and the inner peripheral surface of the rice washing tank, where they are subjected to washing with the rotating stirring blade. At this time, the core may be rotatably supported in the rice washing tank, and the stirring blade may be rotated together with the core by attaching the stirring blade to the core. Only the stirring blade provided separately from the child may be rotated with respect to the central axis of the rice washing tank.
[0014]
In the water-saving rice washing machine as described above, there is rice and rice washing water, and the area that receives the washing with the stirring blade is a relatively peripheral portion of the rice washing tank, so the peripheral speed when rotating the stirring blade is compared. Even if the stirring blade is rotated relatively slowly, the rice is washed efficiently. Therefore, even if the volume of the entire rice washing area is the same as that of a conventional rice washing machine, efficient rice washing can be achieved throughout the entire area, so the amount of rice washing water can be greatly reduced, and the amount of water used can be reduced. Not only can it be reduced, but also the amount of washed rice polluted water can be reduced, the load on the environment can be reduced, and furthermore, the washing time can be shortened.
[0015]
In addition, the size of the core can occupy the vicinity of the rotation axis with poor rice washing efficiency, and a space for receiving rice and water can be maintained between the outer peripheral surface of the core and the inner peripheral surface of the rice washing tank. However, preferably, the radius r of the maximum diameter portion of the inner periphery of the rice washing tank is R, and the radius r of the maximum diameter portion of the outer periphery of the core is (1/4) R. In the range of ≦ r ≦ (3/4) R, more preferably in the range of (1/3) R ≦ r ≦ (2/3) R, in order to reduce the amount of water used and perform the rice washing efficiently. Convenient.
[0016]
The shape of the rice washing tank is not particularly limited, but from the viewpoint of efficiently receiving rice and washed rice water and discharging washed rice and washed rice polluted water, the rice washing tank has an inner peripheral shape, It is desirable to have a cylindrical part and an inverted conical part connected to the lower part. The core has an inverted conical portion that is substantially similar to the inverted conical portion of the rice washing tank, and has a conical portion above or without a cylindrical portion. It is preferable for maintaining a predetermined space between the inner periphery of the rice washing tank. Further, by making the upper part of the core conical, there is an advantage that a wide opening area for receiving the rice for washing rice and the washing water can be taken from the upper part of the rice washing tank. If a nozzle capable of applying water to the conical portion at the upper portion of the core is disposed in the upper portion of the rice washing tank, it is convenient because rice adhering to the conical portion can be washed away.

According to the water-saving rice washing machine as described above, the rice washing is performed in the space between the inner circumferential surface of the rice washing tank and the outer circumferential surface of the core, so that the efficiency of washing the rice is good and the amount of water used is approximately that of the conventional one. You can save less than half. Similarly, the time required for washing the rice can be shortened. Furthermore, as a result, since the amount of the washed rice polluted water is reduced, the load on the environment is small and the environment is excellent.
[0035]
Next, based on FIG.1, FIG2 and FIG.4, operation | movement of the automatic rice-washing apparatus for one pot rice cooking systems of this invention is demonstrated. First, a rice washing start signal is issued from the control device 29. This rice washing start signal may come from the control system of the pot cooking rice system, or a signal issued by the automatic rice washing apparatus for the pot cooking rice system of the present invention, such as a command to the control device of the field operator. There may be.
[0036]
When a rice washing start signal is issued from the control device 29, the rice metering and feeding device 15 starts operation upon receiving the signal, measures a predetermined amount of rice by the meter 12, operates the rotary drive device 14, and guides it. The pipe 13 is rotated onto the selected one rice washing machine 2, and in this state, the weighed rice is supplied into the rice washing tank 3 of the selected rice washing machine 2. Before and after, the rice-washing water supply device 28 starts its operation and supplies a predetermined amount of rice-washing water from the supply pipe 16 into the rice-washing layer 3 of the rice-washing machine 2 to which rice has been supplied. Subsequently, the selected rice washer 2 starts the rice washing process.
[0037]
The rice metering device 15 starts to operate again after a predetermined time from the first operation, operates the rotation driving device 14, rotates the guide pipe 13 onto the next selected rice washer 2, In this state, the weighed rice is supplied into the rice washing tank 3 of the selected rice washing machine 2. Before and after, the rice washing water supply device 28 also starts the second operation, and supplies a predetermined amount of rice washing water from the supply pipe 16 into the rice washing layer 3 of the rice washing machine 2 to which rice has been newly supplied. Subsequently, the rice washing machine 2 starts the rice washing process. In the same manner, the rice metering supply, the rice washing water supply, and the start of the operation of the rice washing machine 2 are sequentially repeated at predetermined time intervals. As a result, each rice washing machine 2 is The rice washing process is sequentially terminated at the predetermined time interval.
[0038]
After the rice washing process is finished, the rice washing machine 2 that has finished the rice washing process is newly supplied with a predetermined amount of water from the water supply pipe 16, and the valve in the rice discharger 17 is opened, The newly supplied water is discharged to the guide device 18 together. The discharged washed rice and water are guided to a predetermined position by the guide device 18. The timing of this induction is synchronized with the timing of the completion of the rice washing process in each rice washing machine 2, and when each rice washing machine 2 finishes the rice washing process sequentially at a predetermined time interval, The guidance to the predetermined position by the guide device 18 is also performed at predetermined time intervals between the respective rice washing machines 2. In addition, when the completion | finish timing of the rice washing process in each rice washing machine 2 has shifted | deviated from the predetermined | prescribed time interval, the timing of discharge | emission of the washed rice from the rice discharge device 17 is changed, It is possible to adjust the guidance to the predetermined position by the guide device 18 so that a predetermined time interval is provided between the respective rice washing machines 2. When the guide device 18 has its own valve, this adjustment can also be performed by changing the opening / closing timing of the valve of the guide device 18.
[0039]
On the other hand, in parallel with the above rice washing process, the control device 29 also sends a signal to the transport device 26 to transport one rice cooker 23 from the transport line of the system to a predetermined position below the guide device 18, and at that place. Stop and wait for standby. In this waiting rice cooker 23, the rice-washed rice and water discharged from the rice-washing machine 2 which has completed the rice-washing process and guided by the guide device 18 will be input. When the amount of water charged into the rice cooker 23 is less than the amount necessary for rice cooking, an appropriate amount of rice cooking water is supplied into the rice cooker 23 from the rice cooking water supply pipe 22. Whether or not a predetermined amount of rice and water has been put into the rice cooker 23 is confirmed by measuring the weight of the entire rice cooker 23 including the weight of rice, water, etc. with the measuring device W. Is added with rice cooking water as described above, and when the weight has reached a predetermined value, a confirmation signal is sent to the conveying device 26 or the control device 29, and the control device 29 waits for the confirmation signal. Determines that the charging to the rice cooking pot is complete, operates the conveying device 26 again, and carries the rice cooking pot 23 to the conveying line of the one cooking system. Along with this, another rice cooker 23 is newly carried into a predetermined position, and enters a standby state. Needless to say, the rice that has been washed and is discharged from the rice washing machine 2 that has finished the next rice washing process is put into the new rice cooker 23 in the standby state. The automatic rice cooker for the one-pot rice cooking system of the present invention repeats the above-described operation, and puts the necessary amount of washed rice into the rice cooker 23 which is sequentially conveyed under a predetermined position of the outlet of the guide device 18. To do.
[0040]
As described above, according to the automatic rice washing apparatus for one pot rice cooking system of the present invention, since a plurality of rice washing machines are made to correspond to one conveyance line, in principle, the rice washing process is performed per one rice cooker. It is possible to reduce the time required to 1 / number of rice washing machines that use it.
[0041]
Next, operation | movement of the water-saving type rice-washing machine used suitably in the automatic rice cooking device for one pot rice cooking systems of this invention is demonstrated using FIG.5 and FIG.6.
[0042]
When rice and rice-washing water are supplied into the rice washing machine 2, the core 4 starts to rotate, and the stirring blades 5a to 5d also rotate accordingly, and preliminary rice washing is performed. At this time, a water shower 37 may be appropriately applied from the nozzle 36 of the shower ring 10 to the conical portion 4a of the core 4 to wash away the attached rice and the like. At this time, the valve in the drainage device 19 is kept open, and the rice is washed while draining. On the other hand, it goes without saying that the valve in the rice discharging device 17 is closed. The stirring blades 5a to 5d may continue to rotate continuously in the same direction, but it is desirable to reverse the rotation direction every predetermined angle rotation, preferably about 90 degrees rotation, because the rice washing efficiency is improved.
[0043]
When the predetermined pre-washing is finished, all the washing water is once drained, the valve in the drainage device 19 is closed, and the washing water is supplied again from the water supply pipe 16. At this time, the water shower 37 may be appropriately applied from the nozzle 36 of the shower ring 10 to the conical portion 4a of the core 4 to wash away the adhering rice and the like, as in the case of preliminary washing. Since the valve in the drainage device 19 is closed, the water supply is stopped when drainage starts from the overflow drainage port 20. Subsequently, the core 4 is rotated, and the stirring blades 5a to 5d are rotated accordingly, and rice washing is performed. When predetermined rice washing is completed, the valve in the drainage device 19 is opened and drainage is performed. As described above, the water washing, rice washing, and drainage are repeated a predetermined number of times, and the rice washing process is completed.
[0044]
In addition, all the operations of the rice washing machine as described above may be automatically performed according to a predetermined sequence, or the degree of washing the rice is detected while monitoring the turbidity of the rice washing water. You may make it control based on a signal. Further, the operation of the rice washer described above is an example, and it goes without saying that various modifications are possible.

【The invention's effect】
As described above, according to the automatic rice washing apparatus for a single pot rice cooking system of the present invention, a plurality of rice washing machines are organically combined, and the induction of rice washed by each rice washing machine to a predetermined position is predetermined. Therefore, it is possible to efficiently put the washed rice into the rice cooker that is sequentially transported under a predetermined position. According to the automatic rice washing apparatus for one pot rice cooking system of the present invention, since a plurality of rice washing machines are made to correspond to one transfer line, in principle, the time required for the rice washing process is used per one rice cooker. It is possible to reduce the number to one of the number of rice washing machines.
[0046]
In addition, if a water-saving rice washer is used for the automatic rice washing apparatus for the one-pot rice cooking system of the present invention, the rice washing efficiency is good and the amount of water used can be reduced to about half or less compared to the conventional one. An effect is obtained. This effect is particularly remarkable in the automatic rice washing apparatus for a single pot rice cooking system of the present invention using a plurality of rice washing machines.
