A Complete Guide to Efficient Lentil Cleaning & Sorting: Boost Yield and Quality
For lentil processors, purity is profit. Even small amounts of impurities can damage your brand, cause equipment wear, and lead to significant product loss. An efficient cleaning and sorting line is your first and most critical defense.

The Enemy: Common Impurities in Lentils
Stones & Mud Balls: Can damage subsequent processing machines (like dehullers) and are a major consumer safety hazard.
Metallic Particles: Pose severe risks to machinery and can cause sparks.
Immature, Shriveled, or Discolored Grains: Lower the overall grade, visual appeal, and market value of your final product.
Dust, Sticks, and Chaff: Contaminate the product and processing environment.
The Multi-Stage Solution: A Precision Cleaning Process
A single machine cannot remove all impurity types. High yield and quality require a sequential, targeted approach:
Pre-Cleaning & Aspiration: Our Pre-Cleaner and Destoner first removes large and light impurities like stalks, dust, and chaff via air aspiration. It simultaneously separates heavy debris like stones and mud balls using vibration and specific gravity, providing crucial protection for your downstream equipment.
Precise Size Grading: Customizable vibrating screens in our Grading & Cleaning Machine separate lentils by size, removing smaller or broken grains and larger foreign materials. This ensures uniformity, which is vital for consistent dehulling later.
Density-Based Sorting: The core of impurity removal. Our Gravity Separator expertly separates grains of similar size but different weight. It effectively removes remaining light impurities, unshelled peas, and slightly damaged or immature lentils that previous steps missed, dramatically boosting purity levels.
Final Perfection with Color Sorting: For the highest grade, our Optical Sorter is the ultimate tool. Using advanced cameras and AI, it identifies and ejects discolored, defective, or subtly stained lentils that even the human eye can miss. This stage guarantees a product of exceptional and consistent color and quality for premium markets.
