During the operation of the color sorter, the heating device is crucial for the color sorting accuracy of temperature and humidity-sensitive materials. Usually, the humidity and environmental temperature of the materials are monitored by sensors, and when the parameters deviate from the set range, the heating will be automatically triggered (for example, when the humidity of rice color sorting exceeds the limit, the electric heating plate heating track will be activated to prevent sticky particles). Common types of heating devices include silicone heaters with a core of silicone, approximately 1.5mm thick and soft enough to fit the curved surface; ceramic heaters with a stainless steel / galvanized plate as the shell, a mica plate as the core, and customizable wiring; and PTC heaters that achieve constant temperature heating and prevent overheating, which respectively adapt to different heating requirements of the color sorter with their respective advantages.
