Abstract
A method for continuously steaming rice includes the steps of evenly placing rice on a moving carrying surface of a single conveyor belt after the rice absorbed water, primarily steaming the rice by blowing steam to the rice placed on the carrying surface, sprinkling of hot water to be absorbed into the rice, and secondarily steaming the rice by blowing steam into the rice. These steps are performed successively without agitating the rice on the single conveyor belt within a sealed housing. The apparatus has a housing (4, 5) made up of a lower housing member (4) and an upper housing member (5) capable of moving vertically relative to the lower housing member (4). The boundary between the upper and lower housing members (5,4) is sealed by drained water during a steaming step.
