Description of the Related Art Heretofore, in each of the publicly known Japanese Patent Laid-Open Nos. 4-145941, 4-145942, and 4-145943, a rice-polishing machine is provided inside a plurality of cases formed to have a size that can be carried into a store. , A bran tank, a blower, and a stone removing machine are provided respectively, and the unit type rice milling apparatus in which they are connected to each other is described.

[0003]

Among the known unit-type rice milling devices, the relationship between the rice milling machine and the stone removing machine is such that the stone removing machine supplies the rice that has been stone-removed to the rice polishing machine. Since there is a difference in the processing capacity of both devices, usually the elevator and belt conveyor were stopped during the period from the stone removing machine to the rice milling machine, so not only grain jams occurred but also the equipment was difficult. .

[0004]

An object of the present invention is to provide a rice polishing method without grain clogging.

[0005]

Therefore, according to the present invention, a stone removing machine 6 is arranged in the vicinity of the rice milling machine 3, and the rice milling machine 3 and the stone removing machine 6 are connected from the stone removing machine 6 to the rice milling machine 3. The stone removing machine 6 is connected to the discharge gutter 8 of the rice milling machine 3 by connecting with a grain lifting device.
The switching valve 9 for switching between the flow path 24 and the discharge, the upper limit switch 36 and the lower limit switch 37 in the supply hopper 7 of the rice milling machine 3 are provided, and the rice milling machine 3 and the stone removing machine 6 are activated to start the rice milling. The switching valve 9 of the machine is switched to the return flow path 24, and when brown rice is supplied to the supply hopper 12, the stone is removed and supplied to the supply hopper 7. When the lower limit switch 37 is turned on for 20 seconds, the switching is performed. The valve 9 is automatically switched to the discharge side, and when the upper limit switch 36 is turned on, only the stone removing machine 6 is automatically stopped while the above-mentioned grain elevator is in operation, and when the lower limit switch 37 is turned off, the stone removing machine 6 is restarted. The lower limit switch 37
This is a rice polishing method that stops all when 60 seconds have passed since becoming FF.

When 7 seconds are turned off and 60 seconds have passed, all of them are stopped.

[0009]

[Operation] Next, the operation will be described. First, the blower 5 is activated, then the rice milling machine 3 is activated, then the stone removing machine 6 is activated, and the switching valve 9 of the rice polishing machine is energized to the switching valve motor 38 to switch to the return flow path 24. Then, when the stone removing machine 6 is started, when the switch 35 is turned on and the motor 34 is energized, the eccentric wheel 32 is rotated, the rocking frame 30 is rocked, and the wind turbine 28 is rotated. The unpolished brown rice is distributed over the entire surface of the selection plate 33, and stones are discharged from the high brown rice side from the low brown rice side. The brown rice discharged from the lower side at this time is metabolically discharged by the amount supplied from the supply hopper 12. The discharged brown rice flows into the air carrier 15 through the discharge port 14, and the grain inlet between the jet nozzle 25 connected to the blower 5 and the diffuser 26 provided at a distance from the jet nozzle 25. The air of the blower 5 is sucked into the filter 27, and the wind of the blower 5 is filtered by the filter 18.
Further, the lower limit switch 37 is turned on by being discharged into the metal case 1 and continuously supplied to the supply hopper 7. The supplied brown rice is rice-milled by the rice-polishing machine 3 and is discharged by the discharge gutter 8. However, since the initial rice-polishing is semi-glutinous rice, it is returned from the switching valve 9 to the supply hopper 12 of the stone removing machine 6 by the return flow path 24. Circulate. After 20 seconds, the milled rice progresses to completely milled rice, so that the switching valve motor 38 is automatically energized to switch the switching valve 9 so that it drops into the bagging section 10 and bagging is performed. Meanwhile, the bran generated from the rice milling machine 3 is sucked and stored in the bran tank 4.

When the supply is advanced and the upper limit switch 36 is turned on, the switch 35 is cut off and the stone removing machine 6 is automatically stopped. However, when it is automatically stopped, the state shown in FIG. No jams occur because the fried device remains running. When the lower limit switch 37 is gradually turned off and the lower limit switch 37 is turned off, the switch 35 is automatically turned on, the stone removing machine 6 is restarted, and the supply is restarted. The lower limit switch 37 is turned off 60
If the time is kept off for a second, it means that there is no rice to be supplied, so all are stopped.

[Effects of the Invention] Among the known unit type rice milling devices,
The relationship between the rice milling machine and the stone removing machine is that the stone removing machine supplies the stones removed from the stone removing machine to the rice polishing machine to polish the rice, but since there is a difference in the processing capacity of both devices, it is usually changed from the stone removing machine to the rice polishing machine. Since the bucket elevator and belt conveyor were stopped during that time, not only did grain jams occur,
The equipment was also difficult. However, according to the present invention, the stone removing machine 6 is arranged in the vicinity of the rice milling machine 3, and the rice milling machine 3 and the stone removing machine 6 are connected by a fried grain device from the stone removing machine 6 to the rice milling machine 3 to obtain the rice milling machine. The discharge gutter 8 of the machine 3 is provided with a switching valve 9 for switching to the flow path 24 returning to the stone removing machine 6 and discharge, and the supply hopper 7 of the rice mill 3 is provided with an upper limit switch 36 and a lower limit switch 37, Rice milling machine 3 and stone removing machine 6
, The switching valve 9 of the rice mill is switched to the return flow path 24, and when brown rice is supplied to the supply hopper 12, the stone is removed and supplied to the supply hopper 7, and the lower limit switch 3
When 20 seconds have passed since 7 was turned on, the switching valve 9 is automatically switched to the discharge side, and the upper limit switch 36 is turned off.
When it becomes N, only the stone removing machine 6 is automatically stopped while the grain elevator is in operation, and when the lower limit switch 37 is turned off, the stone removing machine 6 is restarted and the lower limit switch 37 is OF.
Since the rice milling method was designed to stop all when 60 seconds have passed since it became F, the grain-lifting device is always driven, and the stone removing machine 6 is stopped and supplied to the rice milling machine 3 or stopped. Since the grain clogging can be eliminated based on the operation stop of the fried apparatus, and only the operation of the stone removing machine 6 is stopped, the apparatus has a feature that it is simple and easy to implement.
