In general, brown rice milled on rice is maintained at 0 ~ 5 ℃ and humidity is 11 ~ 12%. Like this, brown rice with low grain temperature and yield is hard, broken during milling, and broken or cracked. easy. When rice is cooked with rice having such copper flakes, starch is eluted from the cracked portion, and since rice has a high degree of collapse, the rice is entangled, which significantly reduces the taste.

Therefore, efforts have been made to improve the taste of the polished white rice, and a number of devices for increasing the yield of brown rice have been developed.

As such an apparatus, a known brown rice water dispenser which directly sprays water on brown rice is introduced.

Figure 1 is a schematic side cross-sectional view of a known brown rice water extractor, which is taken from the publication No. 1998-010247 (Bulletin).

The adjustment plate 14 is attached, and the lower plate of the adjustment plate 14 is provided with a rotating plate 16 for adjusting the feed rate of brown rice. And the discharge port 18 is formed at the end of the brown rice feed hopper (10).

In order to automatically drop the brown rice discharged from the brown rice feed hopper 10 at a constant speed, the brown rice feed hopper 10 extends into the upper portion of the upper part of the first chute 20 having a predetermined inclination angle. The second chute 22 is extended to the first chute 20. A weight sensor 24 is installed on the bottom of the first chute 20 so as to sense the weight of the falling brown rice, and a rotating plate 26 is installed at a predetermined position of the second chute 22.

The weight sensor 24 is used to control the amount of water sprayed on the brown rice according to the weight of the falling brown rice, and controls the speed of the motor 44 to regulate the amount of water supplied by the pump 46.

The guide hopper 28 is disposed so that the brown rice leaving the second chute 22 at a predetermined distance from the end of the second chute 22 is guided downward without being injected. The guide hopper 28 is provided with a water spraying device 30 for applying moisture to the brown rice entering the guide hopper 28.

On the other hand, in order to supply water to the water spraying device 30, a tank 42 in which water is stored is disposed above the brown rice water heater. The water of this tank 42 is supplied to the water spraying device 30 through the flexible supply pipe 40 by the motor 44.

Next, looking at the discharge configuration of the brown rice sprayed with water, the first screw feeder 50 is installed in the lower portion of the guide hopper 28, the first screw feeder 50 is a screw conveyor, The brown rice is transported while mixing and injecting the water sprayed on the brown rice into the brown rice surface and the brown rice. The first screw feeder 50 is a blade 52 having a large diameter and pitch are both used.

Subsequently, a second screw feeder 60 is provided below the first screw feeder 50, and the inlet 64 of the second screw feeder 60 is an outlet 54 of the first screw feeder 50. Extend in line with and aligned.

The second screw feeder 60 is in close contact with each other by the first screw feeder 50 to separate the agglomerated brown rice and transfer the brown rice to the next step of the netting process. In addition, the second screw feeder 60 has the same configuration as the first screw feeder 50, the blade 62 of the second screw feeder 60 is a diameter and than the blade 52 of the first screw feeder (50) Small pitch wings are used.

The first and second screw feeders 50 and 60 used in such brown rice water immersers differ only in diameter and pitch of the blade from each other, and the other configurations are the same as those of a general screw conveyor. That is, in the drawing, the first and second screw feeders 50 and 60 are U-shaped troughs 51 and 61, shafts 53 and 63, tail end plates 55 and 65, and tail bearings. 56, 66, head end plates 58, 68, and outlets 54, 69 are the basic configurations.

On the other hand, the control panel panel is disposed in the upper right front of the rice cooker according to the present invention, the control panel panel and various switches of the start switch, user setting switch (weight and time setting, etc.) for operating the rice mill Various lamps and indicators are arranged to indicate the weight of brown rice supplied, the water supply state of water, the operating state, and the like.

Hereinafter, a description will be given of the action of the known brown rice hydrant having the above configuration.

First, when the brown rice is supplied and the water is sprayed on the brown rice, the brown rice process is completed, the brown rice is supplied through the inlet 12, the brown rice supply hopper 10, the first chute 20 and the second chute 22 Pass through the drop to the guide hopper (28). At this time, the brown rice passing through the first chute 20 is passed through the weight sensor 24 and the amount of water sprayed is determined according to the detected weight.

On the other hand, according to the operation of the motor 39, the water spray device 30 sprays water to the brown rice entering the guide hopper (28).

The next step is to infiltrate moisture into the brown rice while transporting the brown rice sprayed with water, which is performed by the first screw feeder 50.

Next, the lumped brown rice guided through the outlet 54 of the first screw feeder 50 is separated while being transported, which is performed by the second screw feeder 60.

The first and second screw feeders 50 and 60 rotate screw-shaped wings in the troughs 51 and 61, and the brown rice supplied into the troughs 51 and 61 has its own weight and the wings 52 and 62. Advance while sliding along the surface of the blade (52,62) between the driving force by the).

Through the above steps, moisture is penetrated into the surface and the inside of the brown rice and the yield is improved, and the brown rice after the hydrolysis process is transferred to the next step, the rice milling process.

However, since the known brown rice water dispenser is to improve the yield by the action of the brown rice absorbs moisture in the process of spraying water and mixing the brown rice, even brown rice managed at 0 ~ 5 ℃ is in contact with water Since the water absorption is weak, the effect of improving the yield of brown rice is insignificant and cannot be improved to 15 to 16%, which is the optimum yield of brown rice.

Therefore, even if the use of the known rice rice harvester is inferior in yield improvement, there is a problem that the taste and bad taste is still generated in the polished white rice rice.

In addition, the known brown rice water hydrolysis is dependent on the injection of water, the individual brown rice is a non-uniform hydrolyzate is present in a mixture of high and low brown rice, low-yield brown rice and Friction causes heat. Therefore, the moisture contained in brown rice is evaporated by this heat, rather there is a problem in reducing the yield of brown rice.

The present invention has been made to improve the conventional problems, the object of the present invention is to increase the moisture content of the brown rice by increasing the moisture content of the brown rice by increasing the moisture content of the brown rice by simultaneously humidifying and warming the brown rice, The purpose of the present invention is to improve the taste by preventing the occurrence of scrap and copper scraps.

The following describes the brown rice discharge process (S ₁₀ ).

The brown rice 100 moved to the end of the third mixing pipe 190 is discharged to the white rice milling device through the outlet 196.

When water penetrates quickly into the brown rice 100 by such a series of processes and the water content is approximately 15 to 16%, the brown rice 100 becomes soft to reduce the generation of frictional heat during the white rice milling process, thereby reducing the water reduction rate. As a result, the occurrence of envelops and winters is significantly reduced. In particular, as the brown rice 100 is continuously heated and humidified, the moisture content of all brown rice is improved uniformly.
