Thick / Thin Grader

A Thick / Thin Grader Machine is a precision grading system used in rice milling plants to separate rice kernels based on their thickness, ensuring uniform grain quality and improved product consistency. The machine operates using specially designed slotted or precision-perforated grading screens that accurately classify grains into thick and thin fractions according to their width. Thin, immature, chalky, or underdeveloped grains pass through the slots, while thicker and well-filled kernels continue to the discharge outlet. This process enhances the overall appearance, cooking quality, and market value of the final rice. Equipped with adjustable screen configurations and feed rate controls, the machine can be optimized for different rice varieties and grading standards. Its efficient vibration mechanism ensures smooth material flow, high separation accuracy, and minimal grain breakage during operation. Built with a heavy-duty steel frame, wear-resistant grading screens, and precision-engineered components, the Thick / Thin Grader is designed for continuous industrial use with low maintenance requirements. Available in various capacities to suit small, medium, and large rice mills, it offers high throughput, low power consumption, and reliable performance. By removing thin and immature grains, the machine improves head rice quality, increases product uniformity, meets premium domestic and export specifications, and enhances the overall profitability of rice milling operations.
