Description

[Detailed explanation of the idea] The present invention relates to a device for removing rice bran from polished rice.

Rice bran generally adheres to the surface of polished rice obtained by milling brown rice.

However, since polished rice is sold as is, it has been necessary for consumers to wash the polished rice with water to remove the bran before cooking.

An object of the present invention is to provide a bran removal device for obtaining wash-free rice that can be directly cooked without washing polished rice with water.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes a rotating drum having openings 1a and lb on both sides.
It is moderately sloped in the direction.

The rotating drum 1 is a cylindrical body 4 having numerous ventilation holes 3 on its entire surface.
and a bran trap 5 attached to the inner peripheral surface of this cylindrical body.

The cylindrical body 4 may be, for example, a cylindrical body made of metal or synthetic resin subjected to a punching process, or a net-like body.

Further, the bran trap 5 is made of fibrous felt, breathable cloth, nonwoven fabric, paper, etc., and the material is not particularly limited.

An air ejection duct 6 is provided above the rotary drum 1, and has an air outlet 6a that ejects air over almost the entire length of the rotary drum 1.

On the other hand, on one side of the rotating drum 1 (the lower end of the slope in the figure), a blower duct 7 is arranged to blow out low-temperature and high-temperature air for blowing.

This air can be made to flow from the opening 1a on one side of the rotating drum 1 through the inside of the drum to the outside of the opening 1b on the other side.

In addition, 8 in the figure is polished rice supplied into the rotating drum 1, and 9
Reference numeral 10 indicates a hopper serving as a milled rice supply section provided at the other side opening 1b, and 10 indicates a polished rice storage container provided below the one side opening 1a.

Next, the operation of the bran removing device constructed as described above will be explained. From the supply hopper 9, polished rice with bran on it is fed into the rotary drum 1 which is rotating at a low speed.

The polished rice at the bottom of the rotating drum 1 rubs against the bran trap 5 as the drum rotates, and the sugar attached to the polished rice is adsorbed by the trap 5.

In other words, the polished rice gradually moves lower due to the inclination of the rotating drum 1 and is thoroughly rubbed against the trapping bodies to remove sugar and be polished.

The polished rice from which sugar has been removed falls from the opening 1a on one side of the rotating drum 1 and is stored in the storage container 10.

On the other hand, the sugar adhering to the trapping body 5 is removed from the bran trapping body by the air blown onto the top surface of the rotating drum 1 from the air jet duct 6, and the sugars that are released and floating are
Low-temperature and high-temperature air blown from a blower duct 7 provided at an opening 1a on one side of the rotating drum 1 is discharged to the outside from an opening 1b on the other side of the rotating drum.

In this way, the present invention allows the supply hopper 9 to the rotary drum 1.
The sugar content of the polished rice with bran added to it is completely removed and polished before it falls from the drum, and the sugar content can be discharged without re-adhering to the polished rice. Able to drive.

Note that the rotation of the rotating drum 1 is not only caused by a rotating shaft, but also by a rotating shaft.
For example, it is also possible to rotate the drum by holding the circumferential surface of the rotating drum with a plurality of guide rollers and driving the rollers to rotate.

Moreover, it is more preferable to provide a bran collection bag (not shown) on the sugar discharge side to prevent sugar from scattering to the outside.

Further, in order to prevent quality deterioration and drying due to frictional heat generated from polished rice during operation, low-temperature and high-temperature air is fed into the rotating drum as air for blowing.

As described above, according to the present invention, by using a simple configuration, sugar can be effectively removed from polished rice, thereby making it possible to obtain wash-free rice that does not require washing with water.

In addition, since low-temperature and humid air for blowing is supplied into the rotating drum, it is possible to prevent the temperature of the rice from rising due to friction with the bran trap 5, and to prevent the quality of the rice from deteriorating due to heat. In addition, the rice is humidified with humid air to obtain polished rice that contains an appropriate amount of moisture without being dried, and is thus prevented from deteriorating in taste.
