Wet corn milling data for AI stream and mass-balance review
Corn wet milling separates the kernel into starch, germ, fiber and protein streams.
NAICS 311221 · Wet Corn Milling and Starch Manufacturing
Corn wet milling separates the kernel into starch, germ, fiber and protein streams. The Corn Refiners Association describes that structure, which supports a document task about following material through a branching process. Corn Refiners Association process context
Draw an original process diagram and create a fictional shift sheet for three downstream outputs. Give one stream a wet-mass entry and another a dry-solids entry. Ask an AI assistant to identify the common input and explain which totals can be compared with the evidence provided. Leave a moisture value absent in one record. The reference answer should identify the missing basis instead of presenting a neat but unsupported balance.
Labels should preserve stream names, measurement periods, units, recirculated material and unresolved measurements. For evaluation, add a return stream drawn across the page and a duplicate meter export. Score double counting and mistaken basis conversions independently. A completed table is only useful when its calculation can be reconstructed from the cited entries.
The first sample can use invented meter readings and a simplified diagram. Production diagrams, process settings and third-party instrument exports need an authority review before licensing. Offer the task specification and reviewer key with the sample. A buyer can then assess whether the decision problem fits its model, while commercial terms and any expansion remain tied to that accepted brief.

Original Fiund exercise
A material-balance exercise must preserve wet mass, dry solids and internal return scope
An original abstract branching diagram uses invented stream names and quantities. No actual milling process, recipe, instrument configuration or operating instruction is represented.
| Record | Source | What it records |
|---|---|---|
| WCS1 | Input and external output A | Practice period P input I=100 wet mass units. Output A=30 wet units on the same period. A's meter export E-A appears twice with identical key. |
| WCS2 | Other output rows | Output B=20 dry-solids units with no moisture conversion. Output C=10 wet units. Both link to input I's run. |
| WCS3 | Internal return | Five wet units return within the original process boundary, explicitly not a new external input or output. No full loss, remaining stock or other balance entries supplied. |
Question for the model
Which same-basis external-output subtotal is supported, and what prevents a complete wet-mass balance?
Show the reference answer and checks
WCS1 and WCS2 support a 40-unit wet external-output subtotal, 30 from A counted once plus ten from C. B's 20 dry-solids units cannot be added to wet mass without its missing conversion. WCS3's internal return does not add external flow, and the remaining balance evidence is incomplete. Preserve the common run lineage but leave closure unresolved rather than force a neat total by duplicating a meter export or mixing bases.
- Adding wet and dry-solids amounts without a documented conversion.
- Counting an internal return or duplicate meter row as additional external output.
Fields to preserve
- Run, stream and process boundary
- Defines external versus internal flow.
- Quantity basis and unique event key
- Supports a comparable subtotal.
- Moisture conversion and missing balance evidence
- Limits closure.
Test another case
Supply B's authorized wet equivalent but leave remaining stock absent. Require the subtotal to update without asserting a complete balance.
Use original simplified diagrams and invented readings. Exclude production settings and licensed instrument exports; this fixture provides no operating guidance.
