What Is Rice Processing Machine?
Rice processing machines are designed to process harvested brown rice into edible rice through a series of mechanical steps, such as milling, screening, and polishing. They effectively improve rice processing efficiency, reduce labor costs, and ensure consistent rice quality.
Why use a rice milling machine to process paddy rice?
- Rice milling machines can continuously perform processes such as husking, separation, and polishing, significantly shortening processing time. So it is particularly suitable for processing large quantities of paddy rice, which meets the needs of commercial and large-scale production.
- Compared to manual methods, machine milling allows for more precise control of pressure and friction intensity, resulting in rice grains that are not only uniform in shape and have a low breakage rate, but also have a cleaner appearance and more consistent color.
- The whole rice processing machine is in enclosed or semi-enclosed environments, which can minimize human-induced pollution and lower the risk of impurities being introduced to comply with modern food processing standards.
- Furthermore, using rice milling machines significantly reduces manual labor. A single production line can reduce labor costs by at least 40% and lower long-term labor expenses, which is especially beneficial in regions with rising labor costs.
Working principle of a rice processing machine
Rice processing machines separate rice grains from hulls and bran layers using mechanical force and friction, and then refine the rice to optimize its quality and texture. The basic working principle typically involves the following stages:
- The raw paddy rice first goes through a cleaning system to remove impurities such as stones, dust, straw, and metal particles. This step not only provides initial quality screening but also effectively prevents severe machine wear.
- Dehulling is the most basic step, where the machine applies pressure or friction to remove the outer hull, transforming the paddy rice into brown rice.
- After dehulling, the resulting mixture of hulls and brown rice needs to be separated using an airflow or gravity system.
- There are also some optional steps, such as milling and polishing, that improve the texture and further refine the brown rice by removing the bran layer to produce white rice.
- If the budget allows and high-quality finished products are required, a color sorter is also a good choice. It can separate the finished product based on color, removing damaged or low-quality grains to ensure consistent product quality.
Each step is designed to minimize grain breakage while maximizing yield and quality.
Applications of the paddy rice milling machine
With the continuous growth in global rice consumption, rice milling machines have been widely used in rice processing systems of varying scales and in different regions, becoming a crucial piece of equipment connecting agricultural production with the food market.
In many developing countries and agricultural regions, using rice milling machines can help farmers process paddy rice locally, reducing transportation costs. Furthermore, transforming paddy rice into milled rice increases its added value and directly boosts agricultural profits.
In large-scale, commercially operated rice mills, it typically serves as the core processing equipment, used for the continuous processing of large quantities of paddy rice to meet the demands of branded and standardized rice production.
Currently, in Asia, Africa, and South America, many agricultural cooperatives and government-supported projects are introducing rice processing machines to improve local food self-sufficiency, increase the added value of agricultural exports, and thereby enhance rice processing infrastructure.
