Multicheck identifies foreign bodies made of plastic: Foreign bodies, such as blue plastic splinters, must not get into food. To ensure that only flawless products are sold, manufacturers must inspect every single packaged good. CLK has developed the Multicheck for this purpose, which is used in multihead weighers to check the flow of goods. In contrast to X-ray and metal detection methods, the optical camera system detects contaminants by their color. The system thus offers an optimal complement to the other two concepts for foreign object detection, because no system alone can offer 100 percent safety.
