Claims

1. The use method of the conveying equipment with the drying function for rice processing is characterized in that: the specific steps are as follows,

s1, pouring rice to be dried from a rice inlet of a rice inlet box, and enabling the interior of a dust absorption chamber to form negative pressure through a negative pressure fan, so that dust mixed with the rice and dust generated when the rice collides with a flow splitting block are sucked into a dust collection box of the dust absorption chamber, and meanwhile, the rice is divided into a plurality of water-flowing rice lines through the flow splitting block to flow downwards;
