[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stone milling machine provided with a stone punching machine that removes debris from brown rice and a rice milling machine that whitens the brown rice removed by the stone punching machine.
[0002]
[Prior art]
Conventionally, when obtaining white rice, brown rice that has been stone-removed each time has been subjected to whitening. This processing step is performed using a stone remover and a rice mill using separate machines, or using a machine equipped with a stone remover attached to the rice mill. The rice was removed. Therefore, brown rice was usually not stone-extracted at the stage of adjusted shipment.
[0003]
By the way, in recent years, the so-called “shop-milled rice / brown rice sales”, a method of selling brown rice as it is on the storefront and polishing the brown rice on the spot according to customer's request, has been increasing in rice grain stores nationwide. The demand for unpolished brown rice at the shipping stage is increasing rapidly.
[0004]
However, the above-mentioned rice milling machine with a stone remover, which is currently on the market, can easily meet the demand for white rice, but cannot meet the demand for unpolished brown rice. In preparation for the shipment of brown rice that had already been completed, a separate stone punching machine dedicated to brown rice shipment was prepared. Therefore, the two types of machines, together with the complexity of preparing and using two types of machines, a rice mill for white rice and a stone remover for brown rice, corresponding to the white rice and brown rice to be shipped respectively. There was a cost and place uneconomical that had to be prepared.
[0005]
[Problems to be solved by the invention]
Accordingly, the present invention has been made based on the above circumstances, and provides a stone-milled rice milling machine that can easily obtain desired white rice or unpolished brown rice with a single machine and is excellent in economic efficiency. The purpose is to do.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. 1 to 3 show a first embodiment of the present invention. Reference numeral 1 denotes a stone-removing rice mill. This stone-removing rice mill 1 has a stone-removing machine frame 3 and a rice-milling machine 4 mounted and fixed on a bottom plate 2 and a stone-removing machine 5 mounted on the frame 3. It is. In the gantry 3, there are formed a tension port 6 and a tension port hopper 7 for introducing brown rice. The hopper 7 communicates with the supply cylinder 9 of the lifting device 8, and the brown rice is raised and lowered below the hopper 7. A screw 10 that pushes out toward the device 8 is arranged.
[0008]
The lifting and lowering device 8 for cerealing brown rice has an endless belt 12 to which buckets 11 for receiving the brown rice from the filling port hopper 7 pushed out by a screw 10 are attached at regular intervals. The bucket 11 containing brown rice is carried upward together with the belt 12 by driving a lifting motor (not shown), and the brown rice is thrown out from the bucket 11 at the uppermost portion whose direction is changed downward. The brown rice thrown out is supplied to the stone remover 5 from the outlet 15 of the lifting device. The stone remover 5 is arranged below the sorter 16 with a sorter 16 that swings in an inclined direction with one side of the stone removed higher and the other brown rice discharge side lowered, a hopper 17 arranged above the sorter 16. And a fan 18 that blows air, and a stone remover motor 19 that drives the sorting panel 16 and the fan 18.
[0009]
On the brown rice discharge side of the sorter 16, a bifurcated lower portion 20 that is bifurcated at the bottom is continuous. A switching device 23 capable of alternately switching the open / closed state with the milled rice culvert 22 is provided. The switching device 23 includes a switching plate 24 that can block either the out-machine downflow trough 21 or the polished rice downflow trough 22, and the out-of-machine downflow trough 21 (or the polished rice side down trough 22). 22 (or the outside downflow ridge 21) is composed of a switching shaft 25 that reverses the switching plate 24, and an operation lever (not shown) that is connected to the switching shaft 25 and protrudes outside the device. . Therefore, when the switching shaft 25 is rotated by the switching operation of the operating lever, the switching plate 24 closes the outboard downstream basin 21 to open the rice milling downstream basin 22, and when the operating lever is switched in the reverse direction, the switching shaft 25 is rotated in the reverse direction, and the switching plate 24 closes the milled rice bowl 22 and opens the outboard machine 21. Reference numerals 40 and 40 are stoppers for holding the open / closed state by the switching plate 24.
[0010]
From the above, it is possible to take out the unpolished brown rice selected by the sorting board 16 to the outside using the outboard downstream tub 21 communicating with the outside of the apparatus. Further, the branch flow lower portion 20 is provided with an overflow basket 27 that is opened immediately below the brown rice discharge portion 26 of the sorting board protruding into the branch flow lower portion 20. When the inside of the branching flow lower portion 20 is filled with brown rice from the brown rice discharge part 26, the subsequent brown rice can be recirculated to the filling port 6 again by the overflow trough 27. ing.
[0011]
On the other hand, the exit of the rice milling side rice bran 22 is disposed above the hopper 28 for the rice milling machine so that the unpolished brown rice can be supplied into the milling chamber 30. A brown rice detection sensor 29 is provided at the lower end position of the hopper 28, and a supply shutter 31 for opening and closing the passage to the whitening chamber 30 is provided at the lower end of the hopper 28.
[0012]
The rice milling machine 4 includes a milling roll 32 in the milling chamber 30. The milled rice at this time is sent from the demolding screen 33 as a separating mill by a suction fan 34 to a not shown mill processing unit. The fine roll 32 is driven by a main motor 35, and the suction fan 34 is driven by a fan motor 36. A resistance plate 37 is provided on the exit side of the whitening chamber 30, and the pressure adjustment by the resistance plate 37 is made possible by adjusting the spring pressure that presses the resistance plate 37. The whiteness can be set stepwise by turning a whiteness dial 38 for adjusting the whiteness. Reference numeral 39 denotes a white rice takeout bowl provided on the exit side of the milling chamber 30.
[0013]
Next, the operation / operation procedure of the above-described stone extraction rice machine 1 will be described.
First, the user selects the switching direction of the switching device 23 depending on whether the unpolished brown rice is necessary or whether the unpolished white rice is necessary. Next, after the brown rice is put into the tension opening 6, the operation switch of the operation panel is turned on, and the screw 10, the lifting device 8 and the stone remover motor 19 start to move, and the stone remover 5 starts operation. At this time, the main motor 35 and the fan motor 36 of the rice milling machine 4 have not moved yet.
[0014]
The brown rice thrown in from the tension entrance 6 is continuously sent in a fixed amount toward the lower entrance of the lifting device 8 as the screw 10 rotates. The brown rice that has flowed into the lifting device 8 is supplied to the hopper 17 of the stone remover from the outlet 15 of the lifting device while being cerealed in the bucket 11. The brown rice supplied from the hopper 17 onto the sorting board 16 is subjected to a stone removing action and separated into brown rice and stone waste.
[0015]
In this way, the unpolished rice after the stone extraction flows into the branching flow lower part 20 and reaches the switching device 23. However, if the switching direction of the switching plate 24 is operated so that the rice milling downflow trough 22 is opened, The brown rice flows into the hopper 28. When the brown rice detection sensor 29 in the hopper 28 is covered with brown rice, the main motor 35 and the fan motor 36 of the rice milling machine rotate with a delay of T time in response to the brown rice detection signal from the sensor 29, and the rice milling machine 4 Operation starts. The time T is provided to prevent shortage of brown rice in the rice mill hopper 28 immediately after the start of rice milling, so that the rice mill 4 is operated after a certain amount or more is accumulated in the hopper 28. Is set.
[0016]
When the rice milling machine 4 starts operation, the supply shutter 31 is opened, and the milled rice roll 32 receives the whitening action of the brown rice and turns it into white rice, which is discharged out of the machine from the rice bran 39 for extracting white rice. By the way, at this time, when the rice milling amount in the rice milling machine 4 is smaller than the amount of brown rice supplied from the stone remover 5, for example, when the rice milling machine is operated in a half-open state without fully opening the supply shutter 31, The brown rice in the rice milling machine hopper 28 is full, and the branch flow lower part 20 provided with the switching device 23 is also full. Then, if the subsequent brown rice from the stone remover 5 is continuously supplied without interruption, it reaches the opening of the overflow bowl 27, so that the excess brown rice that is supplied in excess passes through the overflow bowl 27 and recirculates to the pouring port 6 again. To do. By adopting the recirculation system in this way, rice clogging of the stone remover 5, the lifting device 8 and the screw 10 at the tension port is prevented in advance, and smooth operation is ensured.
[0017]
On the other hand, if the switching direction of the switching plate 24 is manipulated so that the outboard downflow basin 21 is opened, the scoured brown rice supplied from the stone remover 5 to the diverging lower part 20 is transferred by the switching device 23 to the outboard downflow trough. 21 is discharged to the outside of the apparatus and stored in, for example, a bag prepared in advance. At this time, since the brown rice is not supplied to the rice mill hopper 28, the brown rice detection sensor 29 does not operate. Therefore, the main motor 35 and the fan motor 36 of the rice mill do not move. 8 and only the operation of the stone remover 5. As in the case of the rice milling, when the brown rice is full in the outflow slag 21 and the subsequent brown rice exceeds the opening of the overflow sill 27, the excess excess rice from the overflow slag 27 to the squeeze port 6 is obtained. Circulates.
[0018]
FIG. 4 shows a second embodiment of the present invention. The difference from the first embodiment described above is that the filling port 6 is a method of directly feeding brown rice into the stone remover hopper 17, In addition, the brown rice that has been stoned by the stone remover 5 is directly cerealed by the lifting device 8, and a branching flow lower portion 20 whose lower side is divided into two is connected to the outlet 15 of the lifting device. That is. Further, a switching device 23 is provided at a branching portion of the branch flow lower portion 20, one of the outboard downflow tubs 21 that can be opened and closed by the switching device 23 communicates with the outside of the machine, and the other of the milled rice side downflow tub 22 is It is disposed above the hopper 28 of the rice mill 4. An overflow rod 27 communicating with the branch flow lower portion 20 is provided at an upper portion of the switching device 23 in the branch flow lower portion 20, and the lower end of the overflow rod 27 is disposed above the stone remover hopper 17 so as to prevent overflow. The brown rice can be put into the stone remover hopper 17 again.
[0019]
【The invention's effect】
According to the stone-milling machine according to the present invention, a branching lower part provided with a switching device capable of changing the flow direction of the unpolished brown rice is disposed in the middle part between the stone-milling machine and the rice-milling machine.
