Grain Milling, Dry Bulk Food & Feed Handling worked example

Yield Loss at 1.08% target yield loss rate: a worked example in grain milling, dry bulk food & feed handling

Here is what the math looks like when conditions slip. We hold every other input steady and drop target yield loss rate to 1.08%, then walk the calculation through step by step. Calculate milling or feed production yield loss by comparing lost product weight with total input or production weight and a target loss rate.

The inputs for this scenario

  • Lost product weight: 950 lb (held at the documented default)
  • Total grain input processed: 52,000 lb (held at the documented default)
  • Target yield loss rate: 1.08 % (the input this scenario stresses; the baseline uses 1.5)

Working through the calculation

  • The calculation starts from the formula this tool documents: Yield loss rate = lost product weight ÷ total input or production weight × 100.
  • Yield loss rate works out to 1.83 % at these inputs, and this is the headline figure for the scenario.
  • Yield loss gap to target works out to -0.75 points at these inputs.
  • Lost product weight works out to 950 count at these inputs.
  • Total input or production weight works out to 52,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target yield loss rate sits at 1.5% and the headline result is 1.83 %, this scenario lands almost exactly on the baseline at 1.83 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target yield loss rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It captures total mass loss but not where it went; it won't distinguish moisture shrink from dust, spillage, or unaccounted theft without a deeper mass balance.

Results at a glance

  • Yield loss rate: 1.83 % (headline result)
