1. Reasonable flow channel design
The Household Rice Mill has carefully planned flow channels inside. Starting from the feed hopper, the width and slope of the flow channels are calculated. The connecting flow channel between the feed hopper and the rice milling chamber has sufficient width to ensure that the rice can enter the rice milling chamber smoothly without accumulation and blockage at the entrance. In the rice milling chamber, the flow channel presents a certain spiral or inclined direction, which helps the rice and rice to continue to move in the predetermined direction during the rice milling process. For example, the spiral flow channel can use the gravity of the rice itself and some dynamic factors in the rice milling process to make the rice move forward in an orderly manner like on a spiral slide, avoiding stagnation in a certain local area and causing blockage.
2. Component shape and spacing
The shape and spacing design of key components inside the rice mill, such as rollers and screens, is crucial to prevent blockage. The surface of the rollers may adopt special textures or shapes, which can effectively process the rice and push the rice and rice forward smoothly during rice milling. The mesh size of the screen is uniform and the shape is appropriate, which can not only separate the husk from the rice, but also prevent the rice from getting stuck in the hole due to the mesh being too small or the shape being unreasonable. At the same time, the spacing between the roller and the screen is precisely adjusted, which not only ensures the rice milling effect, but also prevents the rice from being squeezed and blocked between the two due to the spacing being too small.
3. Power transmission and stirring mechanism
In terms of power transmission, the design of the Household Rice Mill can ensure the uniform distribution of power during the rice milling process. For example, the power of the motor is transmitted to the roller through a reasonable transmission device, so that the roller rotates at a stable speed. In addition, some rice mills are also equipped with a stirring device inside. This stirring device can gently stir the paddy and rice in the rice milling room to break up the possible local accumulation. Just like stirring particles in a container, the stirring device continuously redistributes the paddy and rice, thereby preventing blockages from forming in a corner or area.
4. Auxiliary design for anti-blocking
Some Household Rice Mills also have auxiliary design for anti-blocking. For example, drainage devices are set up at the parts that are prone to blockage. These devices may be some small scrapers or airflow guiding structures. The scrapers can scrape the rice that may be accumulated regularly or as needed, so that it can return to the normal flow channel. The airflow guiding structure uses a weak airflow to blow away the rice particles that may stick together, ensuring that they can flow smoothly inside the rice mill, thereby effectively preventing the occurrence of blockage and ensuring the normal operation of the rice mill.
