It determines the purity of input product with exceptional accuracy within a split second. On the basis of colour, shape or other optical properties, defective items and foreign material are identified and separated from the product stream. Its main fields of application are rice, grains, beans and pulses, tea and coffee, seeds and spices, nuts, dehydrated vegetables and recycled plastics.
High-resolution monochromatic and bichromatic visible cameras detect the subtlest product defects and foreign matter. Optional InGaAs cameras can detect and clearly differentiate between many foreign materials based on invisible optical properties.
Optional profile technology is another high-performance tool: product defects are identified through a combination of various parameters such as shape, size and colour.
