[0019]
In addition, the automatic rice milling apparatus 11 is configured so that the input hopper 12 and the white rice tank 18 can be put in and out from the passenger cabin side 11a, and a button operation unit (not shown) on the partition wall 11c for selecting the rice processing contents, A control unit (not shown) that controls the operation of each device in a coordinated manner is provided.
[0020]
The charge tank 2 is provided with a guide portion 21 for guiding the white rice from the forwarding path 4, as shown in FIGS. This guide portion 21 is provided with an inclined portion 22 so as to spread the white rice received from the forwarding path 4 in the corner portion of the charge tank 2 over a wide range of the charge tank 2, and is configured to be widened toward the lid 8 covering the charge tank 2. Install it as a unit.
[0021]
Specifically, as shown in FIG. 7 which is an enlarged exploded perspective view of the guide portion 21, an exhaust port 6a is opened at the upper end of the guide portion 21, and a mesh material is formed at the bottom surface extension position of the forwarding path 4 below the exhaust port 6a. Is formed to form the ventilation portion 6. The outlet 5b of the blower 5 is arranged in communication with the lower side of the ventilation portion 6, and a guide plate 23 is provided to be inclined below the ventilation portion 6. The guide plate 23 allows the mesh material of the ventilation portion 6 to be removed. The broken rice that has leaked downward is returned to the charge tank 2.
[0022]
By the guide portion 21 configured as described above, when the white rice heading from the forwarding path 4 toward the charge tank 2 passes through the ventilation portion 6 along the mesh material, each grain receives a diffusion action by receiving upward airflow. The air is uniformly blown and cooled, and the charge tank 2 is widely dispersed and deposited. By this distributed deposition, the entire inside of the charge tank 2 is uniformly sucked and cooled. Accordingly, it is possible to efficiently ensure uniform quality while suppressing uneven cooling. In addition, since the crushed rice that has fallen from the mesh material of the ventilation section 6 is returned to the charge tank 2 by the guide plate 23, it is possible to prevent the crushed rice from entering the blower 5 side due to stagnation and accumulation of the crushed rice.
[0023]
The above-structured automatic rice milling device 11 with a rice milling function is provided with a switching unit (not shown) that can be selected in two ways in the discharge path of the rice milling machine 3, and an outlet is formed on the cabin 11 a side at the front position of the rice milling machine 3.

[0024]
Specifically, the processing unit brings brown rice or the like to be processed into the insertion hopper 12 on the guest room side 11a, inserts a coin at the button operation unit, and performs a button operation according to the user's wishes, so that the control unit The apparatus is operated and controlled in a coordinated manner, and the polished rice and the polished rice after the polishing process can be taken out from the polished rice tank 18.
[0025]
That is, brown rice to be polished is put into the feeding hopper 12 and the user selects a rice milling button so that the foreign matter is removed by the stone removing machine 14 through the stone removing elevator 13 and then passed through the rice lifting elevator 15. White rice can be obtained from the white rice tank 18 by whitening the brown rice tank 16 with the rice mill 3. In this case, the whitening pressure can be changed by adjusting the whitening degree according to the whitening degree setting button of the button operation unit, so that the whitening degree setting buttons such as “upper white”, “standard” and “8” can be changed. Polished rice can be processed.
[0026]
In addition, when the rice polishing process is desired as well as the rice polishing process, the user presses the rice polishing button of the button operation unit to control the switching unit to send white rice from the rice mill 3 to the charge tank 2, and again, By returning the rice milling machine 15 to the brown rice tank 16 from the elevator 15 for rice milling, changing the setting of the rice milling machine 3 to the polished rice pressure and operating it, it is sent to the white rice tank 18 so that it does not cause quality deterioration due to excessive temperature rise. Then, it can be processed in a series until Kenken.
[0027]
In this case, setting with the milling degree setting button is not necessary, and even if the milling degree setting button is pressed after the polishing button, the milling degree set in advance (for example, without depending on the milling degree setting button) By configuring the control unit so that the rice polishing process is performed after the rice milling process of (Kamihaku), the quality of the polished rice with the precision of dehulling treatment in line with the purpose of the rice polishing process is avoided while avoiding complication of the control system. By this, it is possible to secure an optimal polishing effect that is acceptable to the user. Furthermore, by providing a special button for polishing rice and controlling the setting of the rice milling machine 3 so that it operates as the pressure for rice polishing from the beginning, even for users who wish to only study rice, the white rice put into the input hopper 12 is removed. Can respond without hurting.
[0028]
In addition, if the user wants a combination of milling and polishing, the milling process is limited to “Kamishiro” or “Standard”. In addition, it is configured to perform only the corresponding sorting process. Specifically, as shown in the flowchart of FIG. 8, the course check (S3) at the time of completion of preparation by coin insertion and brown rice insertion (S3, S3) sets the rice polishing process in the case of the rice polishing course (S4). In the case of the rice milling course, it is set to the rice milling process (S5). Subsequently, the scouring check (S6) is performed, and if it does not correspond to the scouring, the course check (S7) is performed. Including the elapse of a predetermined time, it is confirmed as a rice milling process (S8).
[0029]
The above control process can prevent troubles based on delicate quality standards that the user expects individually. Further, by the above-described control process, if it is within a predetermined time immediately after the selection of the rice milling course, it is possible to change to the rice polishing course, so that the user's erroneous operation can be remedied.
[0030]
Furthermore, by providing a reset button separately, it is possible to widely relieve erroneous operations. For example, by checking the reset button, the operation can be stopped if applicable, the coin can be returned, and the device can be reset to restart the operation.
[0031]
Next, the control process in the case of a charge shortage during the process of milling rice will be described. If there is a fee shortage during the milling or polishing process, the course check (S3) is performed after the completion of coin insertion and brown rice insertion (S1, S2), as shown in the flowchart of FIG. . In the case of the rice milling course, it is set to the rice milling process (S4), and then the charge check (S5) is performed. When the fee is insufficient, the same course selection (S9) is continued (S10) by waiting for additional coin insertion (S7) after the device is stopped (S6) and turning on the rice milling button (S8).
[0032]
On the other hand, in the case of Kenken course, the Kenning process is set (S11), and then the fee check (S12) is performed. In the case of insufficient fee, after the apparatus is stopped (S13), after waiting for additional coin insertion (S14), the same course can be continued by configuring in the same manner as above, and the course selection is checked here ( By performing S15), the course selection at that time can be configured.
[0033]
At this time, if the polished rice course is selected again, the polished rice processing is continued (S16). If the polished rice course is selected, the rice is already polished after switching to the polished rice processing (S17). By performing (S18), it becomes possible to respond to a request according to the circumstances of the user.
