Product behaviour
Normal settling and uneven surfaces are included when the acceptance method is developed.
Powder & granular products
Automated powder fill-level and missing-product inspection for bottles, jars and tubs, with vision or alternative sensing, reject systems and trend monitoring.
Application-led inspection
Powders settle, mound, cling to container walls and create dust. The inspection point and acceptance rule must allow for normal product behaviour while still separating a genuine underfill, overfill or missing fill.
How it works
A camera may view the powder surface directly before capping, inspect through a transparent pack wall, or work with another sensing method where the container is opaque. Representative samples establish the normal variation and realistic reject limits.
Normal settling and uneven surfaces are included when the acceptance method is developed.
Equipment placement and enclosure can be designed around the production environment.
Inspection, tracking and rejection are engineered around the existing conveyor and controls.
Suitable applications
Final suitability and performance are confirmed against representative samples, pack formats and real line conditions.
Buyer specification
Powder can settle, mound, bridge, create dust and vary in bulk density. The inspection point and acceptance logic must be chosen around those behaviours rather than assuming a perfectly flat fill surface.
Choose an open-pack view or a sensing method that is not blocked by the closure, label or opaque wall.
Separate acceptable surface texture and settling from a genuine low, high or missing fill.
Apply product recipes, track the pack, reject failures and monitor drift in the filling process.
Practical answers
Final performance is application-specific and is confirmed using representative packs, products and line conditions.
Ask an engineerA camera can inspect from above while the tub is open if the powder surface is visible. Once an opaque closure hides the contents, X-ray, weight or another sensing method may be required.
Not by itself. Bulk density and settling can change the relationship between height and mass. If weight is the critical requirement, the inspection strategy should include an appropriate weighing method.
Often yes, with suitable enclosure, lens protection, cleaning access and controlled lighting. The environmental and hygiene requirements are included in the mechanical design.
