Abstract

PURPOSE:To smoothly discharge polished rice, to prevent bran from sticking to a discharge port and to prevent generation of the ball of bran. CONSTITUTION:A rice milling chamber 4 is formed between a rice milling roll 2 and a bran eliminating cylinder 3 by surrounding the outer circumference of the rice milling roll 2 fixed to a vertical rotary shaft 1 by the bran eliminating cylinder 3. A discharge chamber 6 is surrounded by an outer wall 10 around the vertical rotary shaft 1 and formed in either of the upper position and the lower position of the rice milling chamber 4. In this rice milling machine, the discharge port 11 of a discharge chamber 6 is opened in the tangential direction of the outer wall 10 as the discharge port 11 of the rice milling machine.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge port of a rice polishing machine.

[0002]

2. Description of the Related Art In the publicly known Japanese Patent Publication No. 62-47066, the outer periphery of a rice polishing roll fixed to a vertical axis of rotation is surrounded by a bran removing barrel to polish rice between the rice polishing roll and the bran removing barrel. A chamber is formed, and a discharge chamber surrounded by an outer wall centering on a vertical rotation axis is formed at a lower position of the rice polishing chamber, and a discharge port of the discharge chamber is opened at a right angle to a center line of the discharge chamber. It describes the outlet of the rice mill.

[0003]

In the above-mentioned known device, the discharge port 11 of the discharge chamber 6 is formed at a right angle to the center line as shown in FIG. However, there is a problem that the rice balls collide with the corners of the discharge port 11 and the bran adheres to the corners to form bran balls.

[0004]

Therefore, according to the present invention, the outer periphery of the milled rice roll 2 fixed to the vertical rotation shaft 1 is surrounded by the bran removing tube 3 and is provided between the milled rice roll 2 and the bran removing tube 3. In the one in which the rice cleaning chamber 4 is formed and the discharge chamber 6 surrounded by the outer wall 10 centering on the vertical rotation axis 1 is formed at either the upper position or the lower position of the rice polishing chamber 4, The outlet 11 is a discharge port of the rice milling machine which is opened in the tangential direction of the outer wall 10.

[0005]

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a vertical flow-down type rice milling machine, 1 is a vertical rotating shaft, 2 is a rice polishing roll fixed to the vertical rotating shaft 1, 3 is a bran removing cylinder surrounding the outer periphery of the rice polishing roll 2, 4 is a rice polishing roll 2 A rice polishing chamber formed between the rice bran cylinders 3, 5 a brown rice tank for supplying brown rice to the rice polishing chamber 4, 6 a discharge chamber for dropping and discharging the polished rice from the rice polishing chamber 4, and 7 a discharge chamber 6 The attached resistance valve, 8 is a discharge gutter, and 9 is a rotary pulley fixed to the vertical rotary shaft 1.

[0006] However, the conventional discharge chamber 6 has a horizontal cross-sectional shape as shown in Fig. 3, in which a discharge port 11 is formed at a right angle to the center line in a part of the outer wall 10 of a concentric circle. However, in the present invention, the outlet 11 is opened in the tangential direction of the outer wall 10 as shown in FIG.

FIG. 2 shows an example of a vertical rising rice mill,
12 is an ascending spiral, 13 is a grain feeding cylinder that surrounds the ascending helix 12, 14 is an inlet formed in a part of the grain feeding cylinder 13, 15 is a grain feeding chamber between the ascending helix 12 and the grain feeding cylinder 13, The discharge chamber 6 is formed in the upper part of the rice polishing chamber 4, and the discharge chamber 6 is also formed with a discharge port 11 in the tangential direction.

[0008]

[Operation] Next, the operation will be described. In FIG. 1, the brown rice that has flowed into the rice polishing chamber 4 from the brown rice tank 5 is milled by the rotation of the rice polishing roll 2, the bran is removed to the outside through the eyes of the bran removing tube 3, and the polished rice is polished rice 4 Then, it falls in the discharge chamber 6 and is taken out to the discharge gutter 8. At this time, in the conventional one, the discharge port 11 of the discharge chamber 6 was formed at right angles to the center line as shown in FIG.
Although there is a problem that the rice balls collide with the corners of the discharge port 11 and the bran adheres to the corners, it becomes a bran ball. However, in the present invention, since the discharge port 11 is opened in the tangential direction of the outer wall 10, as shown in FIG. It is discharged smoothly.

[0009]

According to the present invention, the outer periphery of the milled rice roll 2 fixed to the vertical rotating shaft 1 is surrounded by the bran removing tube 3 to form the milling chamber 4 between the rice milling roll 2 and the bran removing tube 3. A discharge chamber 6 surrounded by an outer wall 10 centering on the vertical rotation shaft 1 is formed at either an upper position or a lower position of the rice polishing chamber 4, and the discharge port 11 of the discharge chamber 6 has an outer wall 10. Since it is the outlet of the rice milling machine that opens in the tangential direction of, the polished rice including the bran does not collide with the corner of the outlet 11 as shown in FIG.
Since no bran balls are formed, the bran balls have the effect of not being mixed with the polished rice.
