A diffusion chamber is provided below the hulling chamber to diffuse the hulled rice by the diffusion plate, and the sloping rice is supplied from the diffusion chamber to a down-sliding rice wind path below.

[0003]

In the conventional apparatus,
The rice that has been hulled in the hulling room is diffused by the diffusion plate in the diffusion room and is directly supplied to the down-sliding rice wind selection path. There was a problem that the rice husks were dropped and supplied quickly to the rice-style selection path, and it was difficult to separate the rice husks from the grains, and the sorting performance was not improved. Therefore, the present invention is to solve such a problem.

[0004]

The present invention has the following configuration in order to solve such a problem. That is, a diffusion chamber 29 is provided below the hulling chamber 8 for diffusing rice slid from the hulling rolls 7, 7 by a diffusion plate 28, and a fumarole 30 is provided at the bottom of the diffusion chamber 29. Is guided to the fumarole section 30 and blows upward against the smashed rice in the diffusion chamber 29 during the diffusion and fall, thereby reducing the diffusion and falling speed of the smashed rice and lowering the smashed rice wind path 10 below. Is supplied.

[0005]

When the rice smashed from the hulling chamber 8 is supplied to the diffusion chamber 29, it is diffused by the diffusion plate 28, and then by the fumarole from the fumarole 30 at the bottom of the diffusion chamber 29.
The smashed rice is supplied to the smashed rice wind selection path 10 below with its diffusion falling speed reduced. Therefore, the smashed rice is supplied to the starting end of the smashed rice wind selection path 10 while being slowed down and dropped, and the sorting in the smashed rice wind selection path 10 is facilitated. Can be improved.

[0006]

Embodiments of the present invention shown in the drawings will be described below. First, the overall configuration of a hulling sorter will be described with reference to FIG. The rice hulling sorting machine is a rice hulling unit 1, a rice-slipped rice selection unit 2 that wind-selects the rice slushed from the rice hulling unit 1, and a mixed rice that has been wind-selected in the rice-slipped rice selection unit 2.
