Claim 7:
8. The adaptive quantitative sub-packaging method for the fried rice with the multiple side dishes in the central kitchen according to claim 1, wherein a method for ensuring that the fried rice in the combined material box accurately falls into the primary quantitative station comprises: since when P1=1 and P2=1, the fried rice enters the falling path 1, controlling, by the central control module, the No. 1 material guide plate on a main unloading slideway to be opened upward, and the No. 2 material guide plate to be closed, so as to guide the fried rice in the material box on the unloading station to fall into the packaging container corresponding to the first primary quantitative station; since when P1=1 and P2=2, the fried rice enters the falling path 1, controlling the No. 1 material guide plate on the main unloading slideway to be opened upward, and the No. 2 material guide plate to be closed, so as to guide the fried rice in the material box on the unloading station to fall into the packaging container corresponding to the first primary quantitative station, and controlling a primary quantitative main conveyor belt to convey the packaging container and the fried rice inside the packaging container to the secondary quantitative station, and controlling a packaging container loading mechanism to convey an empty packaging container to the first primary quantitative station at the same time; since when P1=2 and P2=1, the fried rice enters the falling path 2, controlling the No. 1 material guide plate on the main unloading slideway to be closed, and the No. 2 material guide plate to be opened upward, so as to guide the fried rice in the material box on the unloading station to fall into the packaging container corresponding to the second primary quantitative station; since when P1=2 and P2=2, the fried rice enters the falling path 2, controlling the No. 1 material guide plate on the main unloading slideway to be closed, and the No. 2 material guide plate to be opened upward, so as to guide the fried rice in the material box on the unloading station to fall into the packaging container corresponding to the second primary quantitative station, and controlling the primary quantitative main conveyor belt to convey the packaging container and the fried rice inside the packaging container to the secondary quantitative station, and controlling the packaging container loading mechanism to convey an empty packaging container to the second primary quantitative station at the same time; since when P1=3, the fried rice enters the falling path 3, controlling the No. 1 material guide plate and the No. 2 material guide plate on the main unloading slideway to both be closed, so as to guide the fried rice in the material box on the unloading station to fall into the return hopper through the main unloading slideway; and since when P1=0, there is no fried rice in the material box on the unloading station, controlling the No. 1 material guide plate and the No. 2 material guide plate on the main unloading slideway to both be closed; and
a method for guiding the counterweight fried rice of a specific weight to fall into the packaging container on the secondary quantitative station comprises: sensing, by an electronic scale below the secondary quantitative station, a total weight M1 of the packaging container above the scale and the fried rice inside in real time, and starting, by the central control module, a secondary quantitative feeding device to work, wherein when L−M1>0, the counterweight fried rice with a weight of L−M1 is conveyed into the packaging container, such that the total weight of the secondary quantitative packaging container and the rice inside the secondary quantitative packaging container is equal to a set value L; when L−M1=0, the total weight of the fried rice in the packaging container is equal to the set value L, and no counterweight is required; when L−M1<0, the total weight of the fried rice in the packaging container has exceeded the set value L, and the fried rice is treated as overweight; and the counterweight fried rice does not contain the key side dish H_i, and the rest of the formula, technology, and equipment are all identical to the finished fried rice to be sub-packaged in the process I of the step I.
