In general, a large lunch box such as a school or a military service serves meals to a large number of people, and therefore, a large amount of rice must be washed at once to cook rice for the number of people.

However, in the related art, since a large amount of rice was repeatedly washed several times depending mainly on manual labor, rapid washing was not possible, and also a lot of manpower and time were required for washing. In addition, since washing a large amount of rice by hand inverted at the same time, the washing of the rice was not made clean, and the washing of the rice caused the loss of rice due to overflow of water.

In view of the various problems described above, in recent years, various kinds of semi-machines for automatically washing rice are developed and used.

At this time, the water in the reservoir 12 is also filled in the pump 21 through the recovery pipe (18b).

Subsequently, after the rice is supplied into the water tank 11 and the blower 16 is operated while continuously supplying water into the water tank 11 with the tap cock 14b, the air generated by the blower 16 is introduced into the air blowing pipe. Since the water is ejected into the water tank 11 through the air outlet port 15a of the water 15, the water and rice are rotated in the water tank 11, and washing is performed, and the water overflowed from the water tank 11 is discharged through the drain pipe 11b. The water is discharged to the first drain pipe 17, and at the same time, the water and foreign matters mucked out by washing the rice is discharged through the drain pipe 11b, and the washing and rinsing of the rice are gradually performed.

At this time, the air blowing pipe 15 is formed spirally from the top to the bottom in the water tank 11, as shown in Figures 2 and 4, a plurality of air blowing holes (15a) are formed along the spiral direction, the water tank 11 Since the air is blown out from the upper and lower parts of the air, and the air blow holes 15a are formed in plural in the circumferential direction of the air blower pipe 15, the air is blown out in the water tank 11 in all directions. Therefore, since the air is ejected from the upper and lower portions in the water tank 11 in all directions, the water and the rice in the water tank 11 may be irregularly turned to further increase rice washing efficiency.

When washing and rinsing of rice in the water tank 11 are completed as described above, the water cock 14b is locked to stop supply of water, and the first operating lever 21a is operated to open and close the first drain pipe 17. When the valve 17a is opened, water and rice in the water tank 11 are discharged to the connection portion 17c with the circulation pipe 18a through the first drain pipe 17, and then to drive the pump 21. When the water in the reservoir 12 is circulated through the recovery pipe 18b and the circulation pipe 18a, the water is strongly ejected from the nozzle 23, and the water is strongly ejected from the connection portion 17c with the water. Since it is pushed toward the discharge tube 19, the rice contained in the water tank 11 is moved through the circulation tube 18 and the discharge tube 19 together with the water, at this time discharge as shown in the virtual line state of FIG. When the pipe 19 is rotated to face the colander 13 provided adjacent to the water tank 11, the rice in the water tank 11 is supplied to the colander 13 with water.

Therefore, water is discharged to the reservoir 12 through the fine hole 13a formed in the colander 13, and is ejected to the nozzle 23 through the recovery pipe 18b-pump 21-circulation pipe 18a, The washed rice is put in a colander (13), and at this time, the rice can be divided into two colanders (13), so that the transport of the colander (13) is convenient.

At this time, the reservoir 12 is added to the water of the water tank 11 supplied with rice to the existing water, the water level is gradually increased, the water level is a counter flow prevention valve 11a connecting the water tank 11 and the reservoir 12 When it is higher than the () position, the non-return valve 11a is to flow only from the reservoir 12 to the water tank 11, the water overflowing from the reservoir 12 is introduced into the water tank (11).

Subsequently, when all of the rice in the water tank 11 is discharged to the colander 13, the discharge pipe 19 is rotated to face the water tank 11 again, and the first operation lever 21a is operated to operate the first opening / closing valve. When the door 17a is closed, the water in the reservoir 12 is recovered to the water tank 11 through the recovery pipe 18b, the pump 21, the circulation pipe 18a, the nozzle 23, and the discharge pipe 19. When the water level of the reservoir 12 is gradually lowered and positioned at the bottom of the colander 13, only rice remains in the colander 13. In this state, the driving of the pump 21 is stopped to stop the water recovery so that the constant water is always stored in the reservoir 12.

As such, the water recovered in the water tank 11 is relatively clean water used for rinsing rice, and can be recycled in the next rice rinsing, and water can be saved by repeating the rinsing and rinsing and water recovery operations. Likewise, when the rice is discharged, water is discharged to the bottom to prevent splashing or rubbing around.

Subsequently, when the rice is rinsed and the water of the water tank 11 or the reservoir 12 is discharged to the outside, or the water tank 11 and the reservoir 12 are washed with water and then all are discharged to the outside. 3 When the operation levers 21a, 21b and 21c are operated to open the first and second on-off valves 17a and 17b of the first drain pipe 17 and the on / off valve 20a of the second drain pipe 20, Through the first drain pipe 17 and the second drain pipe 20, the water in the water tank 11 and the reservoir 12 may be discharged to the outside.

As such, the present invention efficiently meets the hygiene regulations according to the “Hazards Critical Control Points” of HACCP, while the rice washing process and the process of storing the washed rice are carried out efficiently.
