Legende HFC Series Optical Sorting System

Freshly harvested coffee cherries arrive with a wide range of quality variations — overripe, underripe, and damaged cherries mix alongside healthy fruit, while foreign materials such as leaves, twigs, and stones are commonly present. At this early post-harvest stage, effective sorting is critical: defective cherries left in the batch can compromise cup quality and flavor consistency downstream, while over-rejection erodes valuable yield from an already time-sensitive harvest window. For processors committed to delivering consistent cup quality, vision-based sorting is the key to separating the good from the bad — efficiently, reliably, and at minimal cost.

The Legende HFC Series is a cost-effective vision-based sorting system tailored for freshly harvested coffee cherry sorting. Leveraging high-resolution RGB (HR-RGB) imaging technology, the system delivers high-efficiency detection and removal of defective cherries and foreign materials at the post-harvest stage — providing automated, consistent sorting built for both precision and throughput at an accessible price point.

Using application-specific sorting algorithms, the system ensures consistently high accuracy across diverse cherry conditions — helping processors deliver consistent cup quality and flavor, maximize usable yield, and prepare clean, uniform product for downstream processing with confidence.

Processing Capacity Range: 3000-10000 litre per hour
