high speed and high precision
Coffee and tea capsules are a mass product and are manufactured at high speed. The capsules must therefore be tested at the same high speed. At the same time, the capsules must be tested with high resolution to make even the smallest defects visible. This places high demands on the camera system.
In the case of coffee capsules and tea filters, the sealing surface, the outlet holes and some auxiliary elements necessary for processing the capsule in the coffee machine are usually tested.
The outlet holes and sealing surface of coffee capsules are usually tested in transmitted light. For other types of defects, additional lighting can be used. We have a selection of different powerful transmitted light sources to choose from and select the appropriate lighting for each coffee capsule.
EXAMPLES OF DIFFERENT CAPSULES
We have already tested a large number of different coffee and tea capsules with our systems. Here is a small selection of different types.
