[0002] A dryer for rice processing is a mechanical device specifically designed to reduce the water content of rice to ensure that the rice does not mildew or deteriorate during storage. This equipment is crucial for ensuring the quality of rice and extending its shelf life.

[0003] Chinese Patent Publication No. CN219178175U, published on June 13, 2023, discloses a rice dryer with a screening and impurity removal device, including a stabilizing frame. A drying component for rice production is fixedly connected between the two sides of the stabilizing frame. The drying component includes a moving track plate fixedly connected between the inner walls of the two sides of the stabilizing frame. A moving sleeve is movably sleeved on the surface of the moving track plate. Power wheels are fixedly connected to both sides of the inner wall of the moving sleeve. An adjusting telescopic rod is fixedly connected to the middle of the bottom of the moving sleeve. A paving plate is fixedly connected to the bottom end of the adjusting telescopic rod. A dust collector is fixedly connected to the top of the moving sleeve.

[0004] For example, through the setting of the drying component of the existing dryer for rice processing, the device can directly level the uneven rice poured in through the air inlet pipe. The height of the rice is reduced and evenly paved, which is convenient for drying and heating, and the heat is evenly distributed. It can stably and continuously output. With the setting of the dust collector, it can directly absorb the debris mixed in the rice processing. In the specific implementation process, after the rice is dried, it needs to be manually taken out and then the subsequent rice is quantitatively put in, and so on. The continuity of rice drying is poor, reducing the drying efficiency of the rice. Therefore, it is urgent to propose a corresponding dryer for rice processing to solve the above problems.

[0015] 2. In the present application, in the process that the hollow rod cooperates with the spiral blade to push the rice material away from the mesh cylinder, the hot air flow derived from the nozzle contacts the rice material in the stirring state, which improves the contact effect between the rice material and the hot air flow. At the same time, the rice material in the agitated state cooperates with the high-speed hot air flow to achieve self-screening, that is, the impurities carried by the rice material can fall into the bottom of the outer bin through the mesh holes of the mesh cylinder until they are derived through the impurity removal port, thereby achieving efficient drying of the rice material and filtering of the rice material.
