Color Sorter

A rice color sorter is an optical sorting machine that uses cameras and controlled air ejection to remove discolored grains and unwanted materials from rice. Installed near the final stages of a rice mill line, it helps improve visual quality, grade consistency, and packing standards with stable, repeatable sorting results.

What it removes

• Yellow or aged kernels and unevenly colored rice

• Black spot, mildew-stained, or heat-damaged grains

• Chalky, immature, or broken-looking off-color kernels

• Foreign seeds and small plant impurities that pass grading screens

• Dark contaminants and non-rice particles mixed in the product stream

• Abnormal pieces that reduce finished rice appearance and uniformity

  
  

Where it fits in a rice mill line

1. Rotary cleaning machine → 2) Destoner → 3) Husking & separation → 4) Rice whitener / rice polisher → 5) Rice grader → 6) Color sorter → 7) Packing Material transfer between steps is commonly handled by an elevator and belt conveyor, while a dust collector supports cleaner operation at key transfer points.

   
   

Key selection factors

• Capacity match: sorter throughput should align with your rice grader output and daily production target

• Sorting objective: define what defects you must remove and the acceptable carryover rate

• Integration & layout: inlet/outlet positions, height, and connection to belt conveyor or elevator systems

• Air and dust management: stable air supply plus dust control improves sorting stability; plan connection to a dust collector

• Discharge control: consider how rejects and finished rice are directed, including bin switching via gate valve arrangements

FAQ

Q1: What capacity color sorter do I need for my rice mill line?

A: Choose a color sorter that matches or slightly exceeds the hourly output after the rice grader. Share tons/day, working hours, and product grades, and we can recommend a suitable configuration.

Q2: Do you provide installation and training for color sorters?

A: Yes. We support installation guidance, commissioning, and operator training covering parameter setup, product changeover, cleaning routines, and basic troubleshooting to keep sorting stable.

Q3: How do you handle overseas spare parts and service?

A: We support exports to 20+ regions and can prepare a recommended spare parts list. Service support is arranged with clear communication channels to help reduce downtime and maintain performance.
