Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a finished rice separating device in a rice hulling device.

In addition to attaching a paddy/brown rice sorting device to a hulling device, the present invention also includes a waste rice separating device for separating rice scraps from finished rice separated by the sorting device, and the waste rice separating device Dust can also be separated and removed by passing the wind from the windmill attached to the device.

In the present invention, a paddy/brown rice sorting device 10 and a waste rice separating device 16 for separating rice waste from finished rice separated by the sorting device are attached to a hulling device, and the waste rice separating device 16 is attached to a side wall 17 of the rice waste separating device 16. is formed of a breathable net or a porous member, and the rice waste separation device 16 is installed facing the sorting air path of the rice hulling device 1, and then the rice waste separation device 16 is installed inside the rice waste separation device 16. This is a structure of a finished rice separating device in a hulling device configured to allow a sorting air to pass through.

One embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a hulling device, which houses a case 8 which also serves as a base and has a substantially rectangular shape. A pair of hulling rolls 3, 3 are mounted on a shaft at the bottom of the hopper 2, an air passage 4 for absorbing rice husks, etc. is formed at the bottom of the hulling rolls 3, 3, and a mixed grain receiving trough for paddy and brown rice is formed at the bottom of the hopper 2. 5,
Above the mixed grain receiving trough 5 is a conveying shell spiral 6 for transversely transporting the mixed grains.
be mounted on the shaft.

Both ends of the grain feeding spiral 6 protrude from the support case 8 of the rice hulling device 1, and an elevator 7 is provided on the protruding side of one end so that the protruding side of the grain feeding spiral 6 faces the grain input port at the lower end. Adjacent to the side of the hulling device 1 is a support case 8 having the same size as the hulling device 1, and on the support case 8 is a W.
A paddy/brown rice sorting device 10 is placed via a swinging device 9 that swings in the direction of the arrow. The sorting device 10 has a swinging side L on the J- side and a swinging side H on the opposite side, and when viewed from the front, the side near the elevator 7 is the supply side 12 and the opposite side is discharged. As for the side 13, the height of the supply side 12 is inclined higher than that of the discharge side 13. Reference numeral 14 denotes a sorting board 14 of the paddy/brown rice sorting device 10, which is formed into a multistage type with several stages as shown in the figure.

The discharge side 13 is provided with about 2 to 3 partition plates, with the discharge port closer to the shaking upper side H serving as a brown rice outlet, and the unhulled rice outlet located closer to the shaking lower side L; A mixed grain discharge port for intermediate grains is formed at. A brown rice discharge port formed on the discharge side 13 of the sorting board 14 opens through a gutter 15 to a supply port of a separately installed finished rice waste separation device 16. The waste rice separator 16 has side walls 17 and 18 formed of a mesh or a porous material, one side wall 17 being located on the outside, and the other side wall 18 being connected to the opening 23 on one side of the case 8 that also serves as a base. Provided in contact with each other. The opening 20 on the other side of the support case 8 is connected to the suction air passage 4 of the hulling device 1, and a suction blower 22 is attached to the end of the suction air passage 4. In addition, in the figure, 11 is a storage tank,
Reference numeral 19 denotes a flow plate provided in the case 8 which also serves as a support base, and the flow plate 19
is high on one side and low on the other side, and guides the grains sucked from the waste rice separator 16 to the grain feeding spiral 6.

21 is a rotary sorting cylinder.

(effect) Next, we will discuss the effect.

After each part is rotated by a motor installed at an arbitrary position, unhulled rice is supplied to the supply hopper 2, and while passing through the hulling rolls 3, the unhulled rice is hulled and falls downward.
Light-weight rice husks are removed by suction through the suction air passage 4, and mixed grains such as unhulled rice, brown rice, and husks are transported out of the machine by a grain feeding spiral 6 or the like and flow into an elevator 7, which is a grain lifting device.

The mixed grains fried by the elevator 7 are immediately stored in the storage tank 11, and are discharged from the discharge port via a separator. Then, it is supplied onto a special sorting board 14. Since the sorting board 14 is moved obliquely up and down in the W direction by the swinging device 9, the rice is separated into brown rice, unhulled rice, and mixed grains according to a known theory, and each grain is discharged. Then, the separated unhulled rice flowing out from the unhulled rice discharge port is transferred to the supply hopper 2. A large amount of unseparated mixed intermediate grains, which are returned to the interior and subjected to the hulling action again together with new raw materials, flow out from the mixed intermediate grain outlet, flow down the inside of the cylinder, reach the top of the grain feeding spiral 6, and are successively removed. There are some that merge with new mixed grains that fall. The finished rice discharged from the brown rice discharge port flows through the drain 15 and flows into the waste rice separator 16, where the waste rice is separated by the rotary sorting cylinder 21. In this operation, the finished rice is stirred. Therefore, a large amount of bran powder etc. is generated.

Therefore, in the present invention, the suction air of the suction blower 22 reaches the inside of the case 8 which also serves as a support, and the side wall 17 of the waste rice separation device 16 is formed of a material such as a net or a perforated plate, and the support is Since it is in contact with the opening 23 on one side of the dual-purpose case 8, the air flowing in from the side wall 17 passes through the inside of the rice waste separator 16 and exits from the side wall 18, and all dust etc. is air-separated during that time. The dust-laden air flows on the flow plate 19 and reaches the suction air path 4, thus removing all the dust in the waste/rice separator 16. The present invention has the above-mentioned configuration and function, and in particular, since the hulling device 1 is equipped with the unhulled brown rice sorting device 10, it is possible to completely separate the unhulled brown rice, and in addition to the sorting device 10, there is also a scrap rice separating device. 16 is installed, and the waste rice separator 16 is able to separate the finished rice, so that the finished rice can be made without waste rice. 17 and 18 are made of a breathable material such as a net or a perforated plate, and are attached to the suction air path 4 of the suction blower 22 of the hulling device 1, so that the interior of the waste rice separation device 16 is Since the air of the suction prower 22 can pass through, only the waste rice can be removed.
It is also possible to remove dust such as bran, resulting in even more beautiful finished rice.
