Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rice milling facility that performs a whitening process on input grains.
[0002]
[Prior art]
There is known a rice polishing apparatus that polishes polished rice that has undergone whitening with a rice milling apparatus to finish the milled rice with very little wrinkle adhesion, so-called washing-free rice. And since this washing-free rice does not need to wash rice when cooking, interest in washing-free rice has become strong recently.
[0003]
[Problems to be solved by the invention]
Even if it is said that the grain is made to be non-washed rice, the state of the grain is various. For example, there is a case where it is desired to finish the rice to the state of non-washed rice by subjecting the brown rice that has not yet undergone whitening to the rice polishing treatment.
[0004]
On the other hand, in the whitening treatment of brown rice, if the polishing process is performed, the working time is increased, so that there is a case where only the conventional whitening process is desired without the polishing process. However, in the case where it is desired to perform both the whitening treatment and the rice polishing treatment as described above, conventionally, it is necessary to take out the polished white rice that has been once put into the rice polishing apparatus and then put it into the rice polishing apparatus again. In addition, it is necessary to provide separate inlets for the rice milling apparatus and the rice polishing apparatus, which requires space. In addition, when the rice milling apparatus and the rice polishing apparatus are simply connected to perform the milling process and the polishing process, there is a disadvantage that the milling process cannot be used when only the milling process is desired.
[0005]
An object of this invention is to respond | correspond to the process of various grains by combining a conventional rice milling apparatus and a rice polishing apparatus rationally.
[0006]

[0020]
Next, a description will be given of an operation process (pattern 1) in which unpolished rice, that is, brown rice, is only subjected to whitening processing by the rice milling apparatus S and discharged to the white rice tank 4. First, a coin or a prepaid card as a charge is inserted into the coin insertion slot 50 or the prepaid insertion slot 51, then brown rice is introduced into the raw material insertion tank 5, and when the whiteness is selected with the whiteness selection button 53, the compression plate 21 is set to a predetermined position, and each part of the apparatus in the rice milling facility F starts operation.
[0021]
When each part of the apparatus in the rice milling facility F starts operation, the brown rice in the raw material charging tank 5 is fed out by the rotary valve 11 and cerealed from the hopper part 6a of the lifting machine 6 for the stone removing device toward the discharge port 6b. Supplied to the device 7. After the stone contained in the input brown rice is selected by the stone removing device 7, the input brown rice is supplied to the hopper unit 9a of the rice milling elevator 9 and cerealed toward the discharge port 9b. It is set to block the passage 14 side, and the brown rice is supplied to the brown rice tank 15 through the milled rice passage 13.
[0022]
By the way, the brown rice in the brown rice tank 15 is sequentially supplied to the rice mill S, but on the other hand, the brown rice is also supplied to the brown rice tank 15 in sequence and is transported to the brown rice tank 15 more than the amount that can be supplied to the rice mill S. When the brown rice tank 15 is full, the grain is stored up to the rice milling passage 13 and the discharge port 9b of the rice mill lifting machine 9. And if the conveyance grain detection sensor 9c detects the storage state of the grain in the discharge port 9b, it will control simultaneously that the rotary valve 11 will stop and the unwinding of the brown rice in the raw material input tank 5 will stop. Then, when the whitening process proceeds and the brown rice stored in the discharge port 9b is sequentially transferred to the milled rice passage 13 and the brown rice tank 15 and no grain is left in the discharge port 9b, the transported grain detection sensor 9c has no grain. The rotary valve 11 is again driven to start driving out the brown rice in the raw material charging tank 5.
[0023]
The brown rice supplied from the brown rice tank 15 into the milling device S is sent to the milling chamber T through the cerealing spiral 16 and subjected to the milling process by the milling roll 17 and the milling platinum net 19, and then the milled rice is discharged. It is discharged from the exit 20 to the milled rice passage 25. When passing through the polished rice passage 25, the switching valve 26 is set so as to block the polished rice falling passage 29 side, and the polished rice is returned to the white rice tank 4 through the polished rice discharge passage 27.
[0024]
Next, a description will be given of a work process (pattern 2) in which brown rice is whitened by the rice milling apparatus S, then polished by the rice polishing apparatus K and discharged to the white rice tank 4. First, when a fee is charged and brown rice is put into the raw material charging tank 5 and the brown rice polishing rice selection button 54 and the whiteness selection button 53 are pressed, each unit in the rice milling facility starts operation. Then, through the same process as the whitening process (Pattern 1), it is discharged from the polished rice discharge port 20 to the polished rice passage 25. At this time, the switching valve 26 is set to block the polished rice discharge passage 27 side. The polished rice is supplied from the polished rice passage 25 to the polishing rice tank 28 through the polishing rice dropping passage 29.
[0025]
The polished rice in the polishing rice tank 28 is sequentially supplied to the upper polishing room Q by the threshing spiral 30, polished by the action of the polishing rice roll 31 and the polishing rice wire mesh 32, and discharged from the polishing rice discharge port 34. It returns to the white rice tank 4 through the passage 35. Next, an operation (pattern 3) in which polished rice that has already been polished once is introduced and polished is described.
[0026]
First, when a fee is charged and milled rice is loaded into the raw material charging tank 5 and the milled rice selection button 55 for white rice is pressed, each part of the apparatus in the milling facility starts operation. The milled rice is conveyed to the discharge port 9b of the lift 9 for the milling apparatus through the same process as the pattern 1 of milling, but the switching valve 12 is set to block the milling passage 13 side. It passes through the polished rice passage 14 and is supplied to the polished rice passage 25 without passing through the rice milling device S. In the polished rice passage 25, the switching valve 26 is set to block the polished rice discharge passage 27 side. The rice is dropped in the rice polishing passage 29 and supplied to the rice polishing tank 28, and is polished in the rice polishing room Q in the same manner as the pattern 2 polishing.
[0027]
According to this embodiment, by selecting a work process (pattern 1) in which brown rice is only whitened by the rice milling apparatus S and discharged to the white rice tank 4, the whitening can be performed in the conventional work time, and the work time is increased. Can be prevented. In addition, by selecting the work process (pattern 2) in which brown rice is whitened by the rice milling apparatus S, then polished by the rice milling apparatus K and discharged to the white rice tank 4, the brown rice is subjected to whitening and polishing. By treating with both, it becomes clean finished rice, and it becomes possible to finish it into so-called wash-free rice.
[0028]
Furthermore, by selecting the work (Pattern 3) in which freshly polished rice is newly introduced once and polished, the separately purchased polished rice can be newly polished and finished without washing. . As described above, in this embodiment, various desired grain processings are possible. Next, a method for displaying the replacement time of each part of the apparatus in the rice milling facility will be described.
[0029]
The timer counter 56 detects the operating time of the rice milling facility F, inputs the detection result to the control unit R, and inputs the detection result to the personal computer 70 via the line 71 and the modem 72. The display screen 73 of the personal computer 70 displays operating time information for each of the plurality of rice milling facilities F. When any of the rice milling facilities F reaches a predetermined operating time (for example, the cumulative thousandth hour), A message to that effect is displayed on the display screen 73 to notify that it is time to replace parts such as the whitening roll 17 or maintenance time. The administrator looks at the display contents, replaces the parts of the target rice milling facility F with replacement parts, or performs other maintenance such as removing the adhesion of rice cakes. When the predetermined operation time (thousand hours after the previous replacement) is reached again, the replacement time of parts or the maintenance time is displayed.
[0030]
However, the replacement time and maintenance time may be set differently depending on the parts. For example, the grain sending spiral 16 in the rice milling apparatus S is every 1000 hours, the platinum mesh 19 is every 2000 hours, and the whitening roll 17 is every 3000 hours. May be set as the replacement time, and whenever any of the parts to be replaced reaches the set operating time, a message to that effect may be displayed on the display screen. .
[0031]
Further, in particular, the standard for the replacement time of the parts of the rice milling device S may be calculated from the milling capability of the milled rice (that is, the amount of milling processing per hour). For example, FIG. At the same time, it shows that the carrying capacity is reduced due to wear of the cereal helix 16, adhesion of wrinkles, etc., and when it falls below a predetermined carrying capacity D (for example, the amount that can be carried in 6 minutes is 30 kg) Then, it may be displayed on the display screen 73 that it is time to replace the cereals. As for the rice milling apparatus K, as with the rice milling apparatus S, the parts replacement time may be displayed by the rice polishing processing capacity.
[0032]
Next, in the case of the milling process of brown rice of the above pattern 1 as an example of the diagnosis of work progress when each part of the equipment in the mill F is clogged with grains or the equipment is broken and stopped during operation, an example is given This will be described with reference to FIG. First, if each part of the apparatus in the rice milling facility F does not start operation even if the fee is charged and the grain is charged into the raw material charging tank 5 and the whiteness selection button 53 is pressed, the whiteness selection button 53 is considered abnormal. Judgment is made and a message to that effect is displayed on the display screen 73 of the personal computer 70 via the line 71 and the modem 72 (step 1).
[0033]
When the whiteness selection button 53 is pressed and each part of the apparatus in the rice milling facility F starts operation, the lifting machine 6 for the stone remover and the lifting machine 9 for the rice milling apparatus start operating, and the rice polishing apparatus drive motor M with the rice polishing apparatus is operated. When the escaping machine lift 6 and the milling machine lift 6 are stopped without an output command yet, the lifting machine 6 for the pulverization apparatus 6 or the lifting machine 9 for the pulverization apparatus due to clogging inside the lifting machine 9 It is determined that the trip is caused by an overload of the elevator drive motor 62 for the rice milling apparatus, and the fact is displayed on the display screen 73 of the personal computer 70 via the line 71 and the modem 72 (step 2).
[0034]
When an output command is given to the rice mill drive motor M with the rice milling apparatus and the rotational state of the rice milling apparatus S cannot be detected, it is determined that the drive motor M has tripped due to overload when the rice milling apparatus S is in operation. Then, the fact is displayed on the display screen 73 of the personal computer 70 via the modem 72 (step 3). After the drive shaft rotation detection sensor 38a detects the rotation state of the rice milling device S, it has not detected that the whitening process has been completed (for example, the load current sensor 67 has not detected a load current value below a predetermined value). When the drive motor M stops during the whitening process, it is determined that the trip is caused by clogging in the whitening chamber T, and that effect is displayed on the display screen 73 of the personal computer 70 via the line 71 and the modem 72 (step). 4).
