VacuCheck - Optical Quality Control of Cheese Packaging

Correctly vacuum-sealed cheese packaging (pouch bags) shows a characteristic folding pattern at the sealing seams. In case of leaks, this folding pattern does not occur due to air inflow. The CLK VacuCheck utilizes this characteristic for an objective, hygienic, and fast optical quality control of sealing tightness. Specific imaging techniques capture and evaluate the relevant areas. As a result, nearly 100% of all leaky packages can be identified. The system is designed for use in the food industry according to hygienic design guidelines and can be completely opened for necessary cleaning. The optical acquisition eliminates any product-contacting areas.
