Optical Sorter
An Optical Sorter is a high-tech machine used in recycling facilities to automatically separate different materials. It uses cameras and sensors, like the ones in digital cameras, to identify items on a conveyor belt by their color, shape, or material type. Think of it as a very smart robot that can quickly spot and separate plastic bottles from aluminum cans, or remove unwanted items from food products. This technology helps recycling facilities process more materials faster and more accurately than manual sorting. When someone mentions experience with optical sorters in their resume, they typically have worked with these machines in recycling plants, food processing facilities, or waste management operations.
