Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a rice milling device, which combines a grinding-type whitening action, a friction-type whitening action, and a grinding-type whitening action in a series process to achieve a ventilation-friction-type humidification whitening action on polished rice. There is an attempt to mill beautiful glossy white rice with a high yield and a high de-sprouting rate by using and processing the rice.

When milling white rice from brown rice, the friction coefficient of the smooth surface of brown rice grains is rapidly increased using the grinding action of the grinding mill in the initial stage, and the friction pressure inside the milling chamber is reduced during the subsequent friction milling action. Moreover, it generates a powerful frictional force, and the powerful frictional force and stirring action demonstrate efficient milling ability. Each milling chamber is arranged in a series process so that the grinding milling action of the milling mill using a trochanter performs fine particle milling with much lower pressure than the friction milling action, thereby significantly preventing the occurrence of broken rice. After polishing, the milled rice is further fed into the ventilation friction humidification milling chamber, where the surface of the polished rice is moistened to an extremely thin layer and softened. The generated bran and water are removed outside the milling room, the friction effect is maintained, and the vertical grooves of the rice grains are used to remove the bran and polish the rice into beautiful glossy white rice.

In addition, a friction-type whitening chamber is additionally installed after the grinding-type whitening chamber installed during the intermediate stage of polishing, and the finished polished rice is ventilated through the friction-type humidification and polishing chamber to achieve its final beauty. It is sometimes milled to make glossy white rice.

In principle, the friction whitening action is used for the purpose of debudding, and the gist is to use the grinding whitening action for other whitening processes.

In such rice polishing methods, the surface of the polished rice grains becomes rough due to the grinding action, reducing the commercial value of the polished rice. However, in the present invention, in the final step, the surface of the rice grains is polished to a beautiful, ultra-shiny surface using a wet ventilation friction polishing action. Since it can be finished into polished rice, the grinding action, which has a special effect on yield with less broken rice, can be actively utilized without hesitation. The remarkable effect of the present invention is that it is possible to mill beautiful glossy white rice with a high debudding rate and a high yield with little broken rice.

To explain the present invention with reference to an embodiment diagram, a grinding type whitening trochanter 1 is mounted in a perforated whitening cylinder 2 to form a whitening chamber 3,
In the next step, the ventilation friction type polishing trochanter 4 is added to the porous wall polishing tube 5.
In the next step, a grinding type whitening trochanter 7 using an abrasive material with a particle size smaller than that of the grinding type whitening trochanter 1 is installed in a perforated wall whitening cylinder 8. and the whitening room 9,
In the next step, the ventilation friction type whitening trochanter 10 is mounted in a perforated wall polishing cylinder 11 to form a whitening chamber 12, and the ventilation friction type humidifying whitening trochanter 13 is mounted in a perforated wall polishing cylinder 14. The rice milling chamber 15 is a humidifying milling chamber, and the milling chambers 3, 6, 9, 12, and 15 are connected in series to form a comprehensive rice milling apparatus.

The ventilation friction type humidification whitening trochanter 13 is equipped with an air outlet 16 and is mounted on the main shaft pipe 17, and has a humidifying air pipe 18 that communicates with the main shaft pipe 17.
is connected to a water tank 19, and to a blower 20 and a spray device 21.

Each of the whitening rooms 3, 6, 9, 12, and 15 has a supply port 2.
2, 23, 24, 25, 26 and discharge ports 27, 28, 29
, 30, 31, rice lifting machine 32, 33, 34, 35, 3
6 connects the series steps.

The grain surface of the brown rice is lightly ground in the polishing room 3 to gently and quickly increase the friction coefficient without applying too much pressure to the brown rice, and then a strong frictional force is generated in the milling room 6 to remove the sprouts and polish the rice. Next, in the polishing room 9, the rice is ground again to efficiently perform a gentle whitening process without breaking the rice, and then in the polishing room 12, the polished rice grain surface is finished.Finally, in the polishing room 15, the polished rice grain surface is moisturized and softened and immediately peeled off, which is extremely difficult. This method completely removes the aleurone layer that adheres to the longitudinal grooves of the rice grains, giving the rice grains a beautiful glossy surface.

Moisture to be supplied to the milling chamber 15 is made by atomizing water from a water tank 19 using a spraying device 21 and ejecting moist air from the air outlet 16 of the milling trochanter 13 along with wind from a blower 20 to humidify the polished rice grain surface. It is used for polishing and removing rice bran.

In addition, in the gist of the present invention, the number of grinding type whitening chambers and friction type whitening chambers during the integrated process is arbitrary, and ventilation in each whitening chamber other than the ventilation friction type humidifying whitening chamber is arbitrary.
