In the world of large industrial-scale bakeries, producing high quality products with reliable consistency is of vital importance. Any variation in the composition of the ingredients or in the mixing and baking process can lead to very different results. For this reason, the implementation of a good quality control system is essential.
In many production facilities, a visual control by a trained operator at the end of the production line is still the method of choice to insure that the required quality and consistency objectives are met. However, even though human vision is incredibly powerful, this way of working has its downsides. First of all, it becomes very difficult to enforce objective quality standards, not only across different operators, but even for one operator over the course of his shift. Secondly, even the best trained operator will get tired and will find it hard to stay focused on this job. Finally, the cost of human visual inspection is significant. Here is where automated visual inspection solutions come into play and offer significant advantages.
For a Belgian producer of cookies, Vision++ designed a fully automated combined color and 3D visual control system. The system inspects cookies which pass by on a conveyor belt, and performs a detailed inspection of each and every individual product. The system not only inspects the geometrical properties of the product (width, height, circularity, angle of top plane etc.), but also performs an objective color control to ensure consistent baking quality.
This inspection solution’s features in a nutshell:
- Vision technology: a combination of high resolution color imaging and 3D imaging technology.
- A fully customized solution for the inspection of global shape (e.g. width, height, circularity and angle of top plane) and the detection of specific geometric imperfections (e.g. homogeneity of contours).
- Inspection for color consistency, with the ability to apply different criteria and tolerances to different parts of the product.
- Ensures 24/7 compliance to objective quality criteria.
