Description

[Detailed Description of the Invention] This invention relates to a humidified rotating drum type polishing device that is particularly suitable for polishing the surface of polished rice.

Conventionally, various polishing devices have been put into practical use that polish the surface of polished rice by letting it flow down over an inclined screen sieve frame, etc., to remove the fine powder from the aleurone layer that has adhered or adhered to the surface of the polished rice. The release action of the layered fine powder is more effective when the surface of the polished rice is moist to some extent.

This idea was made based on the above knowledge, and while keeping the surface of the polished rice moderately moist in a sealed case, the falling action and rotation action of the punched metal drum can release the fine powder from the aleurone layer on the surface of the polished rice. It is designed so that it can be carried out effectively.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings.

As shown in the figure, a square box-shaped closed polishing case 1
A shaft shaft 5 is provided inside the case 1 and is supported at an angle by bearings 4 on both side surfaces 2 and 3. A drum 7 formed of the above is attached, and the drum 7 is arranged at an angle, while a duct 8 is provided below the drum 7 to cover the bottom of the drum 7, and a bran discharge port 9 is provided in the duct 8.

Above the drum 7, there is a ceiling surface 10 of the case 1.
The drum 7
The lower part thereof faces a grain threshing port 13 provided on the left side surface 2 of the case 1 and leading to the outside of the case.

An electric motor 15 is provided inside the case 1 to rotate the shaft shaft 5, that is, the drum 7 via a pulley 14.

On the other hand, a humidifier 16 is provided outside the polishing case 1.
the humidified air supply pipe 1 of the humidifier 16.
7 is connected to the humidified air supply port 19 at the lower right side of the case 1 via the blower 18, and the humidified air inside the case 1 is connected to the ceiling surface 10 on the opposite side of the grain feeding port 11 of the case 1 to the outside. A humidified air outlet 20 is provided for discharging humidified air, and a regulating valve 21 is interposed in the outlet 20.

If the humidified rotary drum type polishing device is configured as described above, the polished rice fed into the case 1 from the grain feeding port 11 is guided by the discharge port 12 and falls onto the inner surface of the drum 7, and on the way down. being rotated,
Due to the flowing action and rotation action, the polished rice is polished by the mutual friction between the polished rice and the polished rice and the drum, and the grain is removed from the grain discharging port 1.
From 3 onwards, it will be ejected out of the case. The crushed rice and bran passing through the punched metal holes of the drum 7 are collected in a duct 8 and discharged to the outside of the case 1 from a bran discharge port 9.

While flowing down the inner surface of this drum 7, the humidified air supplied into the case 1 from the humidifier 16 evenly contacts the polished rice, so that the surface of the polished rice is moderately moistened.
The ability to remove fine powder from the aleurone layer is further improved.

By changing the opening degree of the control valve 21, the humidity inside the case 1 can be adjusted, and the degree of humidity can be changed depending on the polished rice to be supplied.

As is clear from the above explanation, this invention uses a drum arranged at an angle inside a sealed case to cause the polished rice to flow down and rotate, while the humidified air supplied inside the case is used to spread the surface of the polished rice to an appropriate level. Since it is designed to provide moisture, it is possible to effectively remove fine powder from the aleurone layer adhering to the surface of polished rice, thereby improving the whiteness of the rice.
