The boiling curve, digitized without touching the vacuum pan

The problem

The curve is seen, interpreted and forgotten. And opening the console is not an option.

The boiling curve is seen, the experienced pan boiler interprets it, and it is forgotten. The console exposes no history queryable by lot, and opening it is not a reasonable option: any intervention touches the supplier's warranty and touches the heart of the process. The cost appears when a customer complains about grain size out of range or high moisture. There is no way to correlate this particular strike with this particular complaint, so the discussion runs on memory and the conclusion depends on who was on shift. There is also a quiet succession cost: the veteran pan boiler's knowledge, who does know how to read that curve, sits nowhere the next person can learn it from.

• The boiling curve is seen, the experienced pan boiler interprets it, and it is forgotten. The console exposes no history queryable by lot.
• Opening it is not a reasonable option: any intervention touches the supplier's warranty and touches the heart of the process.
• The cost appears when a customer complains about grain size out of range or high moisture.
• There is no way to correlate this particular strike with this particular curve, so the analysis starts from zero every time.

How it fits the IRIS system

Photo-on-panel mode — no cable, no drive, no warranty touched.

Connect in photo-on-panel mode, without touching the equipment:

The original console is untouched. What changes is that the plant now has, for every strike, the full time curve tied to the lot the system declares active.

• A fixed industrial camera, in a housing rated for a humid environment with sugar dust in suspension, pointed at the pan's panel.
• Optical recognition with a grounded language model interpreting each frame of the panel.
• Reconstruction of the full time curve of the strike and automatic cross-reference with the lot the system declares active.
• The original console is untouched: no cable, no driver, no new firmware. It is an optical read-only device, so it adds no attack surface to the process network.

Before and after

The boiling curve, before and after

Aspect	Today	With iLEAN Connect
History of the curve	None: it lives on the screen	Full time series per strike
Link to the lot	In the pan boiler's memory	Automatic, against the active order
Answering a grain-size complaint	Analysis from zero	The curve of that exact strike
Intervention on the console	Would void the warranty	None: external camera
Console replacement or retrofit	A six-figure line item plus a shutdown	Deferred indefinitely
Humid, sugar-dust environment	—	Housing rated for it

Impact estimate

Impact estimate — to validate against your numbers.

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.

• Estimated payback 5-10 months.
• Indefinite deferral of the console replacement or retrofit CAPEX — typically a six-figure line item with a refining train shutdown attached.
• Fewer strikes out of grain-size or moisture range, because the curve becomes comparable between shifts.
• And the experienced pan boiler's criterion stops being tacit knowledge that leaves with him.

estimated payback of 5 to 10 months, plus indefinite deferral of the console replacement or retrofit CAPEX — typically a six-figure line item with a refining train shutdown attached — and fewer grain size and moisture complaints. *Estimate to be validated*.

And the fair question from the production manager

"What if the camera misreads a digit?" — reading a fixed-layout panel is about as anchored a task as there is [1]. And nothing is decided on a single reading: what is rebuilt is the curve, a time series that one bad frame does not move. If the framing shifts, the system says so instead of carrying on reading wrong.
