For rose color sorter machines, suppliers like Techik, Mmctech, and manufacturers found on platforms like Alibaba (e.g., Hefei Branagh Photoelectric) offer specialized equipment, often using advanced CCD cameras and AI for sorting fresh/dried petals, seeds, or even other food items like blueberries, focusing on precision, capacity (e.g., 800-2000kg/hr), and high-accuracy optical sensors (like FPGA chips and Japanese components) for quality control in floriculture and food processing. 

When choosing, consider your specific needs (freshness, size, volume) and compare technical specs and supplier reliability from these sources.
