It's only the size of a suitcase, yet it can separate 2 kilograms of mixed grains into five-level precision within 30 seconds; it weighs less than 15 kg, and a woman can easily carry it on a tricycle. It enables on-the-spot sorting with zero waiting time for "First Scene". The mini mobile sorting machine is equipped with a 48-megapixel AI vision and near-infrared dual-spectrum technology, allowing it to identify moldy grains, discolored grains, broken rice, glass, and plastic at a glance; its 0.1-mm injection valve enables point-by-point removal, with a 99.5% good product rate, ensuring every bite is safe and reliable. It features a built-in removable 1-degree electric lithium battery with an 8-hour runtime in the field; it supports three charging methods - 220 V, in-car 12 V, and solar panels - allowing it to operate even without internet access. It's a truly "mobile power-equipped" sorting machine, not a "trailing cord-dependent" device. It starts up by scanning a QR code, with cloud models automatically matching; its tool-free quick-disassembling structure allows for three-step residue cleaning, and its IP54-rated waterproof design makes it resistant to mud, dust, and rice bran. Even elderly people can use it without the need for professional engineers to accompany them. Family farms, cooperatives, mobile purchasing stations, live-stream warehouses, mountainous stations... wherever grain is collected, sorting can be carried out on the spot; it directly folds up and fits into a pocket, allowing good grain to fetch good prices and turning inferior grain into feed on the spot, with profits visible in real time. In the past, good grain was suppressed in price by middlemen; today, you can sort, inspect, and set prices on the spot. The mini mobile sorting machine allows every grain's value to be determined by the farmers themselves.
