Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a vertical rice milling machine.

(Prior art) Conventionally, a downward feeding grain feeding spiral d is provided at the upper position of the vertical axis, and a friction rice milling roll c is provided at the bottom thereof, and the outer periphery of the grain feeding spiral d is a concentric grain feeding tube, and the outer periphery of the friction rice milling roll C is concentric A vertical rice polishing machine is known in which each rice polishing machine is surrounded by a bran removal cylinder b having a shape, and the rice bran removal cylinder b is configured to move up and down according to the load, and a supply part a is formed in the upper part and a discharge part e is formed in the lower part. .

(Problems to be Solved by the Invention) As shown in Fig. 1, in the known method, when the grain is fed downward by the feeding spiral d, it vibrates at the entrance part and causes a bridging phenomenon, and due to the resistance at that time. Since the rice bran removal cylinder b is lowered to enlarge the whitening room, the lower half of the whitening room is often made more sparse than necessary, resulting in problems such as low efficiency, poor gloss, and frequent broken rice.

(Means for Solving the Problems) Therefore, the present invention has a downward feeding grain feeding spiral 18 at the upper position of the vertical shaft 25, and a friction rice milling roll 24 at the lower part thereof.
The outer periphery of the grain feeding spiral 18 is a concentric grain feeding cylinder 1.
In 6, the outer periphery of the friction rice polishing roll 24 is surrounded by a concentric bran removal tube 23, and the bran removal tube 23 is configured to move up and down according to the load, and has a supply section at the top and a discharge section at the bottom. In the vertical rice polishing machine, the bran removal and polishing cylinder 23 has the same diameter from beginning to end, and the friction rice polishing roll 24 has a larger diameter toward the bottom, and the polishing chamber 4
2 is a vertical rice milling machine with a smaller volume toward the bottom.

(Example) An example of the present invention will be described with reference to the drawings.
is an outer frame with a window hole 3 on the side;
Attach the opening/closing lid 4 to the. Reference numeral 5 designates a ceiling wall of the outer frame 2. A circular hole is bored in the ceiling wall 5 to form an intermediate lid, and the engaging portion 7 of the hopper 6 is placed on the intermediate lid 8.

A vertical shaft 25 rotated by a motor is provided at the center of the outer frame 2, and a grain feeding spiral 18 for downward feeding is fixed at an upper position of the vertical shaft 25.
A friction rice polishing roll 24 is fixed to the lower part of the rice polishing roll 8. The friction rice polishing roll 24 is formed into a tapered shape in which the lower end is gradually larger than the upper end, and a protrusion 26 is provided on the outer peripheral surface.

The outer periphery of the grain feeding spiral 18 is concentrically surrounded by the grain feeding tube 16, and the outer periphery of the friction rice polishing roll 24 is surrounded by the bran removing and polishing tube 2.
3 to surround concentrically. The rice bran removal cylinder 23 is formed to have the same diameter from beginning to end from the upper end to the lower end. Therefore, the whitening chamber 42 is formed to have a large volume in the upper part and a small volume in the lower part.

The grain feeding tube 16 on the outer periphery of the grain feeding spiral 18 and the bran removing and polishing tube 23 are integrally connected, and the lower end of the bran removing and polishing tube 23 has a dish-like shape whose area gradually decreases toward the bottom. A body 31 is provided.

In addition, 10 is a bran removal chamber, 12 is a handle, 14 is a lower end of the hopper 6, 17 is an upper end of the grain feeding tube 16, 1
9 is a shaft protruding outward from the grain feeding tube 16, 21 is a shaft protruding inward from the frame 2, and 20 is a shaft 19 and a shaft 2.
1, and 27 is a grain feeding cylinder 1.
6 is a spring that constantly lifts the rice bran removal cylinder 23; 28 is a tapered portion formed at the lower end of the friction rice polishing roll 24; 29 is a small diameter portion following the tapered portion 28;
32 is a guide portion, 32 is a discharge port, 33 is a lower end, 34 is a guide, 35 is a support frame, 36 is a discharge port, 37 is a discharge gutter, and 38 is a suction blade.

(effect) Next, we will discuss the effect.

When brown rice is fed from the hopper 6, the grain feeding spiral 18
The rice is supplied into the milling chamber 42 located further down, and is stirred and milled by the protrusions 26 on the outer peripheral surface of the friction milling rolls 24. In the above case, the rice grains sent downward by the grain feeding spiral 18 tend to stay in the upper part of the milling chamber 42 due to their nature, and due to the resistance, the rice grains are rotated, and the rice grains are removed by the action of the inclined rod 20. An attempt is made to expand the volume of the lower half of the polishing chamber 42 by moving the polishing cylinder 23 downward, but the friction rice polishing roll 24 of the present invention has a larger diameter toward the bottom, and the rice polishing cylinder 23 has the same diameter from beginning to end. Because of this, the volume of the lower half of the whitening chamber 42 becomes smaller toward the bottom, so that the pressure is averaged from top to bottom, and the above defects can be prevented.

(Effect) As already mentioned, conventionally, a downward feeding grain feeding spiral d is placed at the upper position of the vertical axis, and a friction rice milling roll c is placed at the bottom of the downward feeding grain feeding spiral d.
The outer periphery of the grain feeding spiral d is surrounded by a concentric grain feeding tube, and the outer periphery of the friction rice polishing roll C is surrounded by a concentric bran removal polishing tube b, which moves up and down according to the load. A vertical rice milling machine having a configuration in which a supply section a is formed above and a discharge section e is formed below is known. However, the known one, as shown in Fig. 1, has a grain feeding spiral d.
When it is sent downward, it vibrates at its entrance, causing a bridging phenomenon, and due to the resistance at that time, the bran removing and polishing cylinder B descends and expands the polishing chamber, making the lower half of the polishing chamber unnecessarily sparse. This results in problems such as low efficiency, poor gloss, and frequent breakage of rice.

However, the present invention has a downward feeding grain feeding spiral 18 at the upper position of the vertical shaft 25, and a friction rice milling roll 2 at the bottom thereof.
4, the outer periphery of the grain feeding spiral 18 is surrounded by a concentric grain feeding cylinder 16, and the outer periphery of the friction rice polishing roll 24 is surrounded by a concentric bran removing and polishing cylinder 23, and the bran removing and polishing cylinder 23 moves up and down according to the load. In the vertical rice milling machine, which has a moving configuration and has a supply section at the top and a discharge section at the bottom,
The rice bran removal cylinder 23 has the same diameter from beginning to end, the diameter of the friction rice polishing rolls 24 increases toward the bottom, and the polishing chamber 42 has a smaller volume toward the bottom, making it a vertical rice polishing machine. Even if the rice polishing roll 23 is configured to move up and down according to the load, the diameter of the friction rice polishing roll 24 is larger as it goes downward, and the diameter of the rice bran removal cylinder 23 is the same throughout, so the volume of the lower half of the polishing chamber 42 is The pressure decreases downward, so the pressure is averaged from top to bottom.
This has the effect of preventing the aforementioned defects.
