The K64C is a single-chute vertical AI color sorter designed for coffee processing where floor space is limited but detection detail still matters. Two intelligent 2 MP area-array cameras per chute read each bean by shape, size, texture and color, while a dedicated 16 TOPS NPU per chute runs the recognition model in real time. High-speed matrix solenoid valves fire the rejects at 1200 Hz, giving accurate ejection without disturbing the good-bean flow.
Imaging, AI inference and ejector control are integrated into one high-speed sorting architecture. Each chute pairs two smart cameras with two NPU computing boxes for low-latency decisions:
Material moves through four steps: dual cameras capture the flow, the NPU models analyze and classify each piece, 1200 Hz valves eject rejects, and accepted material exits through the discharge conveyor below.




Beyond coffee, the same deep-learning platform handles other granular materials where color-only sorting is not enough:
