Pre-cooking processing method for kidney beans by ultrasonic wave and microwave in segmented manner

The invention discloses a pre-cooking processing method for kidney beans by ultrasonic wave and microwave in segmented manner, which comprises the following steps: sufficiently soaking kidney beans, draining, and standing and germinating the kidney beans at normal temperature; performing steam blanching treatment on the germinated kidney beans to obtain pre-cooked kidney beans; putting the pre-cooked kidney beans into water, and further conditioning the material by ultrasonic waves; taking out the kidney beans from the water, draining off the surface moisture, and then performing microwave drying to completely dehydrate the kidney beans and achieve a completely cooked state; and cooling the cooked kidney beans to room temperature, and carrying out packaging treatment. The pre-cooked kidney beans are conditioned through ultrasonic waves, the flow characteristic of material moisture is adjusted, sugar and impurities attached to the surfaces of the kidney beans are removed, the problem of adhesion of materials i
