Corn rice processing method capable of improving content of resistant starch

The invention provides a corn rice processing method capable of improving the content of resistant starch. The corn rice processing method comprises the following steps: degerming and peeling raw material corn; crushing the corn; adding water into corn flour and carrying out continuous high-temperature cooking and extrusion granulation for two times; improving the gelatinization degree of the corn to be 94%-95% by a heat gelatinization process; conveying corn granules into a spiral vibration and hot air drying tower by wind, and drying the corn granules preliminarily in the tower; conveying the preliminarily-dried corn granules by a vibration conveyor belt, and continuously and repeatedly carrying out cold and heat circulating drying for four times, wherein the content of the resistant starch in a product is increased by alternatively carrying out cold-air dehumidification and heating dehumidification for four times until the content of the dextrinized resistant starch in the product reaches 10%; and storing
