Description

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

(Prior art) As shown in Fig. 9, the conventional circulation rice milling machine has a through hole F in the front and back direction formed in the circulation tank E, and a horizontal grain feeding spiral A installed horizontally at the bottom of the through hole F. , a bran removing cylinder B is provided at the lower part of the horizontal grain feeding spiral A, and the horizontal grain feeding spiral A
A resistance valve D is attached to the pressure chamber C at the tip of the rice bran so that it can be circulated as shown by the arrow to remove rice bran and perform circulation elutriation (Japanese Patent Publication No. 36-1118).

(Problems to be Solved by the Invention) The above-mentioned known device has a through hole F in the circulation tank E.
However, since the horizontal grain feeding spiral A is provided at the lower part of the through hole F, and the bran removing cylinder B is further provided at the lower part of the horizontal grain feeding spiral A, assembly is difficult. In addition, since the peeled bran was still circulating together with the polished rice, the polished rice became slightly yellowish due to the oil from the bran seeping out, and beautiful polished rice could not be obtained.

(Means for Solving the Problem) Therefore, the present invention provides a vertically cylindrical circulation tank 5, a longitudinal through hole 16 provided at the vertical center and horizontal center position of the circulation tank 5, and the through hole 16. circulation ascending passages 18, 18 formed on both left and right sides of the tank; a vertical rice milling roll 4 mounted at the center of the through hole 16; A circulation type rice polishing machine comprising a divided bran removing cylinder 14 inserted and mounted in a through hole 16, and a bran chamber formed between the bran removing cylinder 14 and the inner wall of the through hole 16 and communicating with the outside. This is what I did.

(Example) Fig. 10 shows the basic configuration, and 1 is a motor case, inside which a motor 2 is installed. Reference numeral 5 denotes a circulation tank provided at the upper part of the motor case 1. The circulation tank 5 is a vertical cylinder, and a through hole 16 in the front and rear direction is formed in the center thereof. 17 is an inner wall for forming the through hole 16.

This structure is almost the same as that shown in FIG. 9, but it is completely different from the former in that a vertical bran removing tube 14 is provided within the through hole 16.

The upper part of the bran removal cylinder 14 communicates with the inside of the circulation tank 5,
The lower part of the bran removal cylinder 14 communicates with the inside of the circulation tank 5.

Therefore, the grain flowing out from the lower part of the bran removal cylinder 14 is divided into two parts on the left and right sides, and one is circulated upward through the circulation ascending path 18 on the left side and the other through the circulation ascending path 18 on the right side, and is circulated about 10 times. Once it circulates, the pumping process ends. During this time, a large amount of bran is removed from the bran removing cylinder 14 and taken out through the through hole 16.

Therefore, when viewed from the bran removing cylinder 14, the grains circulate from left to right and the bran is taken out from the front and back.

A specific embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a motor case provided below, which is formed to be placed on the floor. A motor 2 is installed inside a motor case 1. A rotating shaft 3 of the motor 2 projects vertically upward, and a vertical rice milling roll 4 is formed around the outer periphery of the rotating shaft 3. A circulation tank 5 formed of a thin iron plate and having a substantially rectangular cross section is integrally connected to the upper part of the motor case 1. The uppermost end 6 of the rotating shaft 3 faces into the circulation tank 5 lower than the upper end of the circulation tank 5. A downward feeding spiral 7 is provided at the upper end of the rotating shaft 3. The downward feeding grain feeding spiral 7 is inserted and attached to the rotating shaft 3 from above. A vertical shaft rice milling roll 4 having protrusions 8 formed on its outer peripheral surface is attached below the downward grain feeding spiral 7. A small diameter part 10 is formed at the bottom of the vertical axis rice milling roll 4, a large diameter part 11 is provided below the small diameter part 10, and a horizontal circular bottom plate 12 is provided below the large diameter part 11. A grain feeding chamber 24 is formed on the outer periphery of the downward grain feeding spiral 7, and a rice polishing chamber 9 is formed on the outer periphery of the vertical rice milling roll 4. The outer periphery of the downward feeding grain feeding spiral 7 is concentrically surrounded by a grain feeding cylinder 13, and the outer periphery of the vertical axis rice milling roll 4 is concentrically surrounded by a bran removal cylinder 14. 15 is an inlet formed on the outer periphery of the uppermost end 6 of the rotating shaft 3; 19 is an outlet formed on the outer periphery of the small diameter portion 10; grains flow in through the inlet 15;
Discharge from 9. A through hole 16 is formed on the outside of the bran removing cylinder 14, and an inner wall 17 is provided on the outside of the through hole 16.
The through-holes 16 are provided so as to form circulation upward passages 18 on the outside of the through-holes 16 in a vertical front view as shown in FIG. It is approximately the same as the lower end and is connected to the lower end of the bran removing cylinder 14, so that the grains falling from the outlet 19 are received on the horizontal circular bottom plate 12, and are pushed by the following grains to ascend the circulation ascending path 18. become. As shown in FIG. 2, the through hole 16 reaches the outer wall of the circulation tank 5 in its longitudinal side view, and is covered with a removable lid 26 and fastened with bolts 27. When the lid 26 is removed, the joint of the bran removing cylinder 14 becomes visible from the outside,
When you slightly insert your hand, the bran removal tube 14 and the bran removal tube 14
The bolt 25 connecting the two can be loosened, and the bran removing cylinder 14 can be attached and detached.

In addition, 20 is a suction fan, 21 is a bran removal cylinder, 22
23 is a discharge gutter, 23 is a discharge valve, and 24 is a grain feeding room.

(effect) Next, we will discuss the effect.

When brown rice is put into the circulation tank 5 and the motor 2 is energized to rotate the vertical axis rice milling roll 4 and the downward feeding grain spiral 7, the grains in the circulation tank 5 flow through the inlet 15 and are downwardly fed. The rotation of the spiral 7 sends it downward. The rice then flows into the rice polishing chamber 9, flows downward through the outflow port 19, rises within the circulation chamber 18, and then flows in through the inflow port 15 again, repeating the cycle. In this case, at which point is the pressure highest? Since the outlet 19 is formed narrower than the rice polishing chamber 9, the pressure inside the rice polishing chamber 9 is highest. That is, in the rice polishing chamber 9, the bran is removed to the maximum extent, and the removed rice passes through the holes of the bran removal tube 14, flows into the through hole 16, is sucked by the suction fan 20, and enters the bran removal chamber 21. It is stored.

As the polishing progresses, the bran removing cylinder 14 will wear out and must be replaced. That time,
Loosen the bolts 27 to remove the lid 26, and remove the lid 26 to expose the bolts 25.
Remove the bran removal cylinder 14 and install a new bran removal cylinder 14.
It is exchanged with.

(Effects) The present invention provides a vertically cylindrical circulation tank 5, a longitudinal through hole 16 provided at the vertical center and horizontal center position of the circulation tank 5, and a circulation tank formed on both front and rear sides of the through hole 16. The rising passages 18, 18, the vertical axis rice milling roll 4 attached to the center position of the through hole 16, and the vertical axis rice milling roll 4 and the vertical axis rice milling roll 4 surrounding the vertical axis rice roll 4 from the outside of the circulation tank 5. Hole 1
This is because the rice polishing machine is a circulation type rice polishing machine consisting of a divided bran removing cylinder 14 that is inserted and mounted in the rice bran removal cylinder 6, and a bran chamber that is formed between the bran removing cylinder 14 and the inner wall of the through hole 16 and communicates with the outside. , B. Even with circulation, the pressure inside the vertical bran removing cylinder 14 can be increased due to the structure in which the water flows downward, so that the bran can be removed rationally and actively, resulting in beautiful, polished rice. .

(b) A box-shaped circulating rice milling machine can be created, which not only has a superior design compared to conventional cast iron products, but is also cheaper because most of it can be done by sheet metal processing.

C. For the rice polishing part, a normal vertical single-pound rice mill can be used as is.

D. The bran removal tube 14 is easy to attach.

This effect is achieved.
