Leveraging Vision Inspection for Improved Quality
Consistent quality in baking is the goal for those looking to maximize yield, reduce waste, and increase profits. With thousands of buns flying down the line every hour, relying on manual sampling is like trying to frost a cake with a fork. Enter vision inspection: an automated, objective, and data-rich solution that lets us fine-tune our processes in real time.
Join us as we share insights from our recent Optimizing Bakery Production with Vision Inspection BAKERview.
Baking with Data
Traditional inspection methods, like manual measurements of bun height or subjective judgments of bake color, are no match for modern production speeds. A human inspector might sample 36 buns per hour. A vision system? Try 45,000. The data difference is staggering!
Let’s take bun height as an example. In a traditional sampling setup, KPM Analytics’ EyePro team measured a mean height of 60 mm with a standard deviation of 0.9 mm. However, after switching to 100% inline inspection, they saw a mean of 59 mm and a standard deviation of 2.1 mm. What changed? Nothing except for the visibility of actual process variation. Sampling bias (like which side of the conveyor you pull from) and measurement bias (caliper pressure differences between operators) skew the results. A vision system eliminates that bias with uniform, objective measurements across every product.
A Loaf of Insight: Process Correlation
To get the most out of your vision system, don’t treat it as a stand-alone QC device. Use it as your process pulse. For each key quality assurance metric, whether it’s product height, bake color, or seed distribution, correlate it back to specific upstream variables:
- Ingredient tolerances: A slight shift in flour moisture can skew volume.
- Scaling accuracy: A few grams off in dough weight translates to bake time drift.
- Proofing parameters: Variability here can impact the rise and final product profile.
- Oven zone settings: Bake color can be balanced with last-zone temperature corrections.
Vision inspection provides that “baker’s eye” across all lines, at all times. No blinking, no fatigue, and no second-guessing.
Slicing Through Challenges with AI & Hyperspectral Tools
The newest icing on the technological cake is AI-enhanced vision. EyePro and KPM Analytics implemented advanced algorithms that detect challenging defects like blisters or “old dough” residue in the heel. These used to pass unnoticed by human inspectors and traditional vision tools. Now, with AI’s help, EyePro’s team can confidently distinguish between acceptable steam holes and unacceptable residue.
Hyperspectral imaging adds yet another layer, allowing us to “see beyond the crust”. It does this by mapping moisture distribution and spotting foreign bodies invisible to metal detectors or X-rays. That’s the kind of insight that lets you rise above the competition.

Crust-Worthy Control Loops
Perhaps the most powerful use of inline vision inspection is real-time process control. Consider our cookie line: a vision sensor monitors bake color at the final oven zone and auto-adjusts the heat profile to maintain a tight +1 to -1 L* target range. It’s like having a master baker adjusting your oven every second, except it never takes a coffee break!
Take A Closer Look with Vision Inspection
For bakeries looking to elevate their operations from reactive to predictive, we’ve got just the resource for you! Our Vision Analysis BAKERpaper breaks down how to move from batch-based thinking to continuous improvement, using data as your most reliable ingredient.
Because leveraging vision inspection systems isn’t just about catching burnt buns or crooked cookies, it’s about understanding your process in high resolution, every second of the day. Download our full white paper and start kneading your way to smarter production.
