Visual cleaning evidence for allergen changes
Application example · Impact to validate
When the line switches from a declared-allergen product to the next batch without it, cleaning must be certifiable. With iLEAN Edge, fixed cameras compare the current state to "clean" and JIDOKA AI blocks startup until OK.
Document visible cleaning conditions before quality approval
Today a supervisor signs off "clean" with no objective evidence; leftover product can contaminate the first new batch.
- This case records visible conditions after cleaning: accessible surfaces, remaining product and tool assembly. Vision does not establish the absence of allergens or replace tests specified by quality. Reference comparison helps identify visible deviations and organize the inspection route before the next product is authorized. The evidence is one part of the release decision.
Preparing this use case at the plant
Edge + JIDOKA AI. Cameras at each critical point with a CNN trained to recognize "clean vs. leftover product". Startup blocked until OK + quality sign-off.
Give each inspection point an agreed reference, camera position and lighting setup. A removed component or displaced camera creates a pending review state, not an automatic clean result. The record combines images, complementary checks and approval. Any startup interlock must be engineered and validated with the plant's engineering team and its authorization procedure before operational use.

Example target, subject to plant validation: blind sign-off with cross-contamination risk → sign-off based on visual evidence per critical point.
Measure results before scaling
The block below is an estimate to be validated against your plant's actual data. We put it forward so the committee has an order of magnitude; we refine it during the assessment.
Protection against non-conformity or allergen-driven recall; payback depends on the weight of allergen-declared references in the mix. Estimate to be validated.
Questions about visual cleaning evidence for allergen changes
Can a clean-looking image release an allergen changeover?
Not by itself. Quality decides using the cleaning procedure and established checks. The camera provides evidence of visible conditions and helps identify overlooked locations. Analytical results and other required verifications stay with the visual inspection record before approval. A favorable image should never be interpreted as proof that invisible residues are absent.
What happens when an inspection point fails?
Return the point to pending, document the action and request another check. Preserve the sequence so the initial inspection remains distinguishable from a later verification. Pilot indicators combine reviewed locations, repeated cleaning and time to authorization without equating a quicker changeover with conformity of the next product. The signature closes the reviewed record, not an assumed state.
