[0009]
FIGS. 5 and 6 show another example of the means for removing the spelled rice. As shown in FIG. 5, the sorting unit 16 having the same configuration as described above is arranged above the swinging sorting plate 31 of the stone removing device 3. Provided. That is, the above-mentioned spelled rice sorting unit 16 is held by the holding plates 17 and 17 attached so as to connect the opposing surfaces 33a and 33b of the swing sorting unit side wall (see FIG. 6). In FIG. 5, reference numeral 34 denotes a selected stone and residual rice discharge unit. Alternatively, the holding plates 17 and 17 connected to the spelled rice sorting unit 16 can be fixed to the handle 50 installed between the swing sorting unit side walls 33a and 33b, and the spelled rice accumulated in the spelled rice sorting unit 16 can be taken out by the handle operation. It may be configured as follows.
In the above description, the stone removing device 3 is provided with the means for sorting the spelled rice. However, when the foreign substance removing device is provided separately from the stone removing device as shown in FIGS. Rice sorting means may be provided in the foreign matter removing apparatus.
[0010]
Next, a description will be given of means for discharging the residual rice in the charging hopper once it is stuck in the apparatus.
Referring to FIG. 2 described above, when brown rice is put into the loading hopper 1 and then a return button (not shown) provided on the operation panel 8 is pushed, the exit of the lifting device 2 and the stone removing device 3 are removed. The brown rice introduced by switching the switching valve 12 provided in the middle is returned to the cabin A so that customers can take it home. However, even if residual rice remains in the charging hopper 1, if it is left as it is, the next customer will use it until the return button is pressed. It was in the failure mode not accepting.
Therefore, after the last rice milling operation is finished and reset, when the grain detection sensor 14 signal provided in the charging hopper 1 is on, that is, when there is a residue in the charging hopper 1, the conveying spiral 13 of the charging hopper 1, The stone lifter 2 and the stone remover 3 are driven so that the residue in the charging hopper 1 is once stuck in the machine and conveyed to the stone remover 3, and the residual rice discharging device 46 is removed from the stone remover 3. The residual discharge process is automatically performed. For example, the forward / reverse motor 45 shown in FIG. 3 is operated and discharged to the machine room (since generally, it is not desired to take home another person's brown rice). As a result, the charging hopper 1 can always be in an empty waiting state, so that the conventional problems can be solved and the next customer can use them without any problems.
[0011]
FIG. 7 shows a rice milling facility having a configuration different from that shown in FIGS. 1 and 2 described above, but the same reference numerals are given to the same parts as in FIGS.
As shown in the figure, when the grain brought by the customer is put into the hopper 1, the grain is drawn out from the hopper 1 by the conveying spiral 13 and conveyed upward by the lifting / lowering device 2 for removing stone. In this configuration, the hulling device 18 is provided, and the grain conveyed by the lifting device 2 is sent to the hulling machine 18 through the hull tank 20. After crushing, foreign substances, stones and the like are removed by the following stone removing device 3 and foreign material removing device 4. Then, it is conveyed upward by the lifting device 5 for rice milling, put into the brown rice tank 11, and then sent to the rice milling device 6. The polished white rice is stored in the white rice tank 7, and the generated rice cake is stored in a rice bag or the like by the rice cyclone 24.
[0012]
Further, as shown in FIG. 8, the rice milling apparatus 6 is configured such that a milling roll 36 is housed in a milling chamber 35, and the koji separated from the dehulling screen 37 is conveyed to the koji collecting means by the koji transport fan 29. Is done. Reference numeral 30 denotes a blower fan that blows air into the whitening chamber 35. The whiteness is adjusted by the compression plate controller 28 based on the setting of the whiteness setting switch on the operation panel 8 and by changing the elastic pressure of the whiteness adjustment spring 27 applied to the compression plate 26 on the outlet side.
By the way, in the case of a coin rice mill having a shell crack detection means, as shown in FIG. 7, the grain (brown rice or rice bran) stuck to the charging hopper 1 is used as the next process device (in FIG. 7, the rice bran device 18). Thus, the body cracking detection sensor 19 is provided in the path of conveyance to the stone removing device 3 in the configuration not including the hulling machine as shown in FIG. In the case of having such a case crack detection means, when the detection value of the case crack detection sensor 19 exceeds a predetermined value and it is determined that the case crack grain is a predetermined ratio or more, regardless of the whiteness set by the customer. Then, the pressure of the compression plate 26 for adjusting the whiteness is changed to be low, and the whiteness is controlled to be lowered. Further, in the rice mill equipped with the rice huller 18, the gap between the rice hull rolls 18a and 18b is set and controlled so as to be wider than the roll gap in the normal operation. Such setting change control of whiteness and the like is performed in preference to the setting of the whiteness setting value on the operation panel 8, and the amount of cracked grains is displayed and changed by the operation of the display operation switch of the customer. It is also possible to display with priority on the set whiteness.
As a result, the generation of broken rice due to cracked grains can be minimized, and clogging of the rice mill can be prevented.
[0013]
Further, in FIG. 7 described above, a conveyance amount detection sensor 21 for detecting whether a predetermined amount necessary for the operation of the rice milling apparatus 6 is conveyed to the milling portion at the start of the rice milling is provided in the brown rice tank 11, and the whiteness after the rice milling A whiteness detection sensor 22 is provided in the vicinity of the exit of the rice mill 6. Further, a switching valve 23 is provided at the outlet of the rice milling device 6 so that the white rice tank 7 side and the circulation path 25 side to the rice milling lifting device 5 can be switched.
With such a configuration, the conveyance amount detection sensor 21 is turned on at the start of the rice milling and the necessary predetermined amount is conveyed. However, the whiteness detection sensor 22 is off and the whiteness does not reach the predetermined value, the switching valve 23 described above. Is switched to the circulation path 25 side, and the grains are circulated in the rice mill. During the circulation of the grain, the driving of the conveying spiral 13 of the charging hopper 1 is stopped, and when the whiteness detection sensor 22 is turned on, the switching valve 23 switches the circulation of the grain to the discharge, and the conveying spiral 13 is Reboot. Thereby, the lifting device load at the time of grain circulation can be reduced.
