Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a rice hulling device.

(Prior Art) A conventional hulling device is equipped with a device that separates mixed rice into brown rice and hulled rice, takes out the brown rice as finished rice, and returns the hulled rice to the head of the hulling unit for reprocessing.

(Problems to be Solved by the Invention) However, the conventional device is expensive, generates a lot of vibration, and has a large volume. Also, the damage to the grain was large.

Therefore, the present invention provides a rice hulling device equipped with a sorting unit using a rotary sorting cylinder that rotates on a horizontal axis, which is inexpensive, has almost no vibration, causes little damage to grains, and has a small volume. be.

(Means for Solving the Problem) The present invention has a rice huller 1 and numerous pot holes 1 on the inner peripheral surface.
1, the rotary sorting tube 12 has one end in the axial direction at a starting end 15 and one at the other end in the axial direction. The mixed rice from the hulling section 1 is conveyed from the terminal end side 14 to the starting end side 15 into the rotary sorting cylinder 12.
5, a mixed rice receiving gutter 16 is provided for feeding into the rotating sorting cylinder 12, and a brown rice receiving gutter 17 is provided in parallel to the mixed rice receiving gutter 16 in the rotating sorting cylinder 12,
The mixed rice receiving gutter 16 and the brown rice receiving gutter 17 are formed with open upper surfaces so as to receive the mixed rice and brown rice scooped up in the pot hole 11 formed on the inner peripheral surface, respectively. The main idea is to configure a hulling device with the terminal end open to the outside of the machine.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. 1 is a hulling section, 2 is a supply hopper at the head, 3 is a pair of hulling rolls attached to the lower part of the supply hopper 2, and 4 is a In the wind selection room, 5 is a suction blower, 6 is the first conveyor, and 7 is the second conveyor. On the side of the hulling section 1, there is a grain lifting device 8 for frying the rice mixed with the hulled rice.
A mixed rice sorting section 9 is provided. Inside the sorting section 9, as shown in FIG. 3, a rotary sorting tube 12 is provided, which is formed by machining a thin metal plate 10 to form numerous potholes 11 on its inner surface. 13 is a rotary sorting tube 12
It is a driving roller that rotates the

The rotary sorting cylinder 12 has one axial end formed at a starting end side 15 and the other end formed at a terminal end side 14,
The terminal end side 14 is close to the supply hopper 2, and the starting end side 15
is located away from the supply hopper 2.

The rotary sorting cylinder 12 has a main part from the terminal end side 14 to the starting end side 1.
A mixed rice conveying device consisting of a mixed rice receiving trough 16 and a conveyor 18 for conveying the mixed rice toward a brown rice receiving trough 17 and a brown rice conveying device consisting of a brown rice receiving trough 17 and a conveyor 20 are provided. The mixed rice receiving trough 16 and the brown rice receiving trough 17 are provided in parallel, and the mixed rice receiving trough 16 is provided closer to the rotation rising side.

A falling part 19 is formed on the starting end side 15 of the mixed rice receiving trough 16, and the falling part 19 opens so as to be biased away from the scooping side of the rotary sorting tube 12. Brown rice catcher 1
The conveyor 20 above 7 discharges the finished rice to the outside of the machine.
A receiving tray 21 leading to the supply hopper 2 is provided on the lower side of the terminal end side 14 of the rotary sorting tube 12 . 22 is a discharge gutter of the grain frying device 8, which is connected to the terminal side 14 of the mixed rice receiving gutter 16.
is connected to.

(effect) Next, we will discuss the effect.

The unhulled rice supplied to the supply hopper 2 is hulled by a pair of hulling rolls 3, the mixed rice of brown rice a and unhulled rice b flows into the first conveyor 6, and the immature grains flow into the second conveyor 7. Light rice husks are sucked into the suction blower 5 and blown out of the system.

The mixed rice that has flowed first into the conveyor 6 is fried by the grain frying device 8, and is supplied from the discharge gutter 22 to the terminal side 14 of the mixed rice receiving gutter 16, and then transferred to the conveyor 18.
, and reaches the starting end side 15 side, and the falling part 1
9 and falls into the rotary sorting cylinder 12.

In this case, since the falling part 19 is opened so as to be biased away from the scooping side of the rotary sorting tube 12, the mixed rice is diffused in the circumferential direction inside the rotary sorting tube 12, and the sorting effect is improved. improve.

In the rotary sorting cylinder 12, the rotation of the rotary sorting cylinder 12 stirs the brown rice a, which has a large specific gravity and is easy to slip, as shown in FIG.
is separated on top of the brown rice a, and therefore, a relatively large amount of the brown rice a that has settled to the lower layer fits into the pot hole 11, and a relatively small amount of the unhulled rice b in the upper layer fits into the pot hole 11, and is rotated and sorted. When the tube 12 rotates clockwise in FIG.
The brown rice a that is deeply fitted in the mixed rice receiving trough 16
Jump over the brown rice catcher 17 and reach the conveyor 20.
A part of the unhulled rice b, which is taken out as finished rice and is shallowly fitted with the remaining brown rice a, flows into the mixed rice receiving trough 16.

Thus, the remaining unhulled rice b taken out to the terminal end side 14 is returned to the head via the tray 21.

(Effects) As mentioned above, conventional hulling equipment is equipped with a device that separates mixed rice into brown rice and hulled rice, takes out the brown rice as finished rice, and returns hulled rice to the head of the hulling unit for reprocessing. It was getting worse. However, the conventional device
It was expensive, caused a lot of vibration, and had a large volume.

However, the present invention provides a hulling device having a hulling section 1 and a sorting section 9 provided with a horizontally rotating mono-barrel rotary sorting tube 12 having numerous pot holes 11 formed in its inner circumferential surface. The cylinder 12 has one axial end formed at the starting end side 15 and the other side at the terminal end side 14 , and the mixed rice from the hulling section 1 is transferred from the terminal end side 14 to the starting end side 15 in the rotary sorting cylinder 12 . A mixed rice receiving trough 16 is provided in which the mixed rice is conveyed and fed into the rotating sorting cylinder 12 at the starting end side 15, and a brown rice receiving trough 17 is provided in the rotating sorting cylinder 12 in parallel with the mixed rice receiving trough 16.
The mixed rice receiving gutter 16 and the brown rice receiving gutter 17 are provided, and the mixed rice receiving gutter 16 and the brown rice receiving gutter 17 are
The top surface of the husk hole 11 formed on the inner circumferential surface is open to receive scooped mixed rice and brown rice, respectively, and the end of the brown rice receiving trough is open to the outside of the machine. Since the configuration is summarized, the mixed rice receiving gutter 16 in the rotary sorting cylinder 12 is as follows:
The mixed rice from the hulling section 1 is transferred from the terminal side 14 to the terminal side 1.
5 and the rotary sorting cylinder 1 at the starting end side 15.
2 and the function of receiving the mixed rice scooped up in the pot hole 11 formed on the inner circumferential surface of the rotary sorting cylinder 12. Therefore, the structure is simple. . Further, since the mixed rice sorted in the rotary sorting tube 12 and scooped up in the pot hole 11 is circulated within the rotary sorting tube 12 without being guided outside the machine, there is little damage to the grains.
