Freshly harvested coffee cherries often vary significantly in quality, with overripe, underripe, and damaged fruits mixed alongside premium ones, frequently accompanied by foreign material such as leaves, twigs, and stones. At this initial post-harvest stage, efficient sorting is critical for quality control: residual defective cherries in a batch can directly compromise subsequent cup quality and flavor consistency, while excessive rejection can unnecessarily reduce precious yields during an already tight harvesting window. For coffee cherry processors, post-harvest sorting is not merely a "cleaning step," but a crucial starting point that determines whether the final product can be delivered consistently and command premium prices.
The Legende HFC Series is a vision-based sorting system tailored precisely for this scenario. Equipped with high-resolution RGB (HR-RGB) VIS imaging technology, it performs real-time scanning and surface feature analysis on coffee cherries. Paired with high-performance air ejectors, it achieves high-precision rejection of defective cherries and foreign material within milliseconds.
This system enables automation and standardization of post-harvest sorting at a lower investment threshold. It not only helps processors find a better balance between quality and yield, but also intercepts flavor-compromising risks at the source, providing a solid guarantee for the exceptional quality of every cup of coffee.
Processing Capacity Range: 3000-10000 litre per hour
