The invention discloses a sterilization process and a sterilization device for processing instant bean products, and relates to the technical field of food sterilization. When a conveying belt drives bean products to move, high-temperature steam is in contact with the bean products and high-temperature sterilization is carried out, due to the fact that the bean products are not turned over in the conveying process, contact dead angles appear during steam contact, and the bean products are not sterilized uniformly. When the bean products are driven by the conveying mechanism to enter the space between the steam exhaust hoods, the bean products in a moving state pass through the inclined guide plate and the material shoveling plate, and are shoveled and turned over in the moving process, so that high-temperature steam sprayed out of the steam exhaust hoods is uniformly contacted with the surfaces of the bean products, and the situation that the sterilization effect is not ideal due to sterilization dead angles is avoided; meanwhile, the side baffles on the two sides are matched with the shoveling plate and the inclined guide plate, so that the bean products are prevented from falling off from the two sides in the process of shoveling and turning over the bean products.
