Optical sorter for rice defect detection
Achieve exceptional sorting precision by detecting and removing color and foreign material defects in rice and grains, ensuring optimal quality in continuous, high-speed operations.
The DR-C RGB Optical Sorter from Bühler is engineered to provide precise sorting and detection of color defects and foreign materials in rice and grain processing. Utilizing high-resolution RGB cameras and powerful sorting algorithms, it efficiently identifies and separates materials with subtle color variations and unwanted impurities such as plastic or glass. Ideal for producing high-quality white, brown, and specialty rice types, as well as grains and pulses, this equipment supports continuous, high-speed operation, maintaining end-product quality up to 99.9%. Integration into existing lines is seamless, with its advanced PLC control system allowing remote monitoring and operation. Energy efficiency is optimized with long-lasting LED lighting, offering full-spectrum illumination for reliable sorting accuracy. Designed with maintenance in mind, it supports quick and efficient cleaning processes, ensuring minimal downtime. Fully trialed and validated at Bühler’s Optical Sorting Headquarters, the DR-C ensures superior performance for food manufacturers and agricultural producers.
