The bottom of the stirring rod 49 is in a plug shape, and in an initial state, the plug-shaped bottom of the stirring rod 49 blocks the rice discharging passage 54.

In this embodiment, the rice steaming device further comprises a controller (not shown in the figure), which is electrically connected to the steam generator, the screw driving motor 13, the bin wall vibrator 14, the turntable driving motor 34, the bottom plate driving motor 35, the rotating motor 44, the lifting motor 45, the drain switch and the electric water valve of the water inlet mechanism.

When the rice steaming equipment works, the controller firstly controls the relevant circuit to start the spiral driving motor 13, and the spiral driving motor 13 drives the spiral strip 10 in the spiral conveying pipe 8 to rotate after being started, so that the rice in the rice storage bin 7 is pumped to the rotary disc 18 of the rice discharging mechanism 3, and the rice pumping process is completed. In the rice pumping process, the controller also controls the related circuit to start the bin wall vibrator 14, and the bin wall vibrator 14 vibrates after being started, so that the rice in the rice storage bin 7 can smoothly fall into the discharging groove 9 for discharging. Then the controller controls the related circuit to start the turntable driving motor 34, the turntable driving motor 34 drives the turntable 18 to rotate around the rotating shaft 23, and in the rotating process of the turntable 18, the three rice falling grooves 22 on the turntable 18 pass through the nine through holes 28 of the partition plate 24, so that the rice on the turntable 18 uniformly falls into the nine quantitative rice taking cavities through the rice falling grooves 22 and the through holes 28 on the partition plate 24. After the nine quantitative rice taking cavities are full, the controller controls the related circuit to enable the turntable driving motor 34 to drive the turntable 18 to rotate to the initial position, and then the turntable driving motor 34 is stopped, so that the three rice falling grooves 22 on the turntable 18 are staggered with the nine through holes 28 on the partition plate 24 again, and then the rice in the turntable 18 cannot continuously fall into the nine quantitative rice taking cavities. Then the controller controls the related circuit to start the bottom plate driving motor 35, the bottom plate driving motor 35 drives the rotating bottom plate 26 to rotate around the rotating shaft 31 until the nine blanking holes 30 on the rotating bottom plate 26 are respectively aligned with the discharge holes of the nine quantitative rice taking cavities, so that the nine blanking holes 30 on the rotating bottom plate 26 are respectively communicated with the discharge holes of the nine quantitative rice taking cavities. At this time, the nine discharging holes 33 at the bottom of the cylinder 17 are aligned to the discharging holes of the nine quantitative rice taking cavities respectively, so the nine discharging holes 30 on the rotary bottom plate 26 are also aligned to the nine discharging holes 33 at the bottom of the cylinder 17, and thus the nine discharging holes 33 at the bottom of the cylinder 17 are respectively communicated with the discharging holes of the nine quantitative rice taking cavities, that is, the nine quantitative rice taking cavities are respectively communicated with the nine rice taking tubes 21, so that the rice in the nine quantitative rice taking cavities sequentially passes through the nine discharging holes 30 of the rotary bottom plate 26, the nine discharging holes 33 at the bottom of the cylinder 17 and the nine rice taking tubes 21 and simultaneously falls into the nine rice washing containers 52 of the rice washing structure 38, thereby realizing the simultaneous uniform rice taking. After the rice is discharged, the controller controls the related circuit to enable the rotary bottom plate 26 to rotate to the initial position, so that the nine discharging holes 30 on the rotary bottom plate stagger the discharging holes of the nine quantitative rice taking cavities and the rice discharging pipe 21 of the cylinder body 17 again, and the rice dividing process is completed.

After the rice is separated, the controller firstly controls the relevant circuit to open the electric water valve, then the water inlet mechanism respectively injects water into each rice washing container 52 through the large branch water pipe 42 and the small branch water pipe 43 of the water inlet pipe 41, because the plug-shaped bottom of the stirring rod 49 blocks the rice discharging channel 54 in the initial state and the drainage switch corresponding to the drainage channel 55 is closed, the water injected into the rice washing container 52 cannot flow out through the rice discharging channel 54 and the drainage channel 55. After the water injection is finished, the controller controls the related circuits to close the electric water valve, then the controller controls the related circuits to respectively start each rotating motor 44 of the rice washing device 16, and after each rotating motor 44 is started, the corresponding stirring rod 49 is respectively driven to rotate and stir the rice in the corresponding rice washing container 52, so that the rice is washed. After the washing is finished, the controller controls the related circuit to make the water inlet mechanism inject a certain amount of water into each rice washing container 52 again, so that the rice washing water in each rice washing container 52 overflows from the top to the water storage space between the rice washing container 52 and the water receiving container 53. In the overflowing process, the floating impurities in the rice washing water overflow together with the rice washing water, so that the rice washing water in the rice washing container 52 has no floating impurities.
