Length Grader

A Length Grader Machine is a precision grading system used in modern rice milling plants to separate whole rice kernels from broken rice based on grain length. It operates using an indented cylinder (trieur) mechanism, where grains are classified according to their length with high accuracy and consistency. As the cylinder rotates, shorter grains and broken rice are lifted into specially designed indents and discharged through collection troughs, while longer whole kernels continue to the outlet. This process ensures efficient separation with minimal grain loss and high grading accuracy. The machine features adjustable cylinder speed, feed rate, and discharge settings to accommodate different rice varieties and grading requirements. Manufactured with precision-engineered, wear-resistant cylinders and a heavy-duty steel frame, the Length Grader is designed for continuous industrial operation with low maintenance and long service life. Its enclosed construction minimizes dust generation and maintains a hygienic processing environment. Available in various capacities for small, medium, and large rice mills, the machine delivers high throughput, low power consumption, and reliable performance. By accurately separating whole rice from broken kernels, the Length Grader improves product uniformity, enhances market value, meets domestic and export quality standards, and maximizes the profitability of rice milling operations.
