Best Practice Compact, flexible and reliable: metal detector allows chocolate treats to be enjoyed safely The chocolate manufacturer Weinrich wanted to integrate a metal detector into its existing production line. Alongside the limited space, the inspection solution also had to be able to cope with the product effect of chocolate and reliably detect foreign objects in the different varieties. Key facts Customer benefits The new metal detection device was to be integrated into an existing production line where the main difficulty lay in ejecting contaminated chocolate bars. Due to the construction of the production line, this could only be resolved through a telescopic belt. Before the chocolate bars pass through the detection coil, they are briefly stopped by a stacking edge to sort the bars into a line. Upon detection of metal, cylinders tighten the telescopic belt after the detection area, resulting in the contaminated products falling below onto another conveyor. This is where they are then inspected by quality management. The compact design of the metal detector means it can be easily integrated Products etal detector Vistus M The customer Since 1895, the Ludwig Weinrich chocolate factory has based its corporate concept on the three cornerstones of tradition, innovation and responsibility.

Weinrich’s world of chocolate offers an exciting mix of tradition and modern trends, every day, every year and surely for several centuries to come. Intuitive operation Reliably ejects products contaminated with foreign objects The OEM solution can be fully adapted to the customer’s requirement

Project goal and implementation Weinrich produces hollow chocolate shapes and chocolate bars at its production facility in Herford. It has relied on products from the global manufacturer Minebea Intec for many years, as can be seen by the many Vistus metal detectors and the X-ray inspection system installed at various points in the production chain. Weinrich using the inspection solution before they are then packed in the next step. The chocolate bars are sorted into a line on the conveyor belt by a stacking edge, before they go through the detection coil. If a foreign object is then detected...
