Grain Milling, Dry Bulk Food & Feed Handling worked example

Yield Loss at 1.73% target yield loss rate: a worked example in grain milling, dry bulk food & feed handling

Push target yield loss rate up to 1.73% and the picture changes. This example computes every intermediate figure at that operating point. Use it when production or quality needs to quantify losses from screenings, fines, dust, spillage, rework, rejected feed, off-spec flour, or handling shrink.

The inputs for this scenario

  • Lost product weight: 950 lb (unchanged)
  • Total grain input processed: 52,000 lb (unchanged)
  • Target yield loss rate: 1.73 % (raised for this scenario; the documented default is 1.5)

Working through the calculation

  • Applying the documented formula (Yield loss rate = lost product weight ÷ total input or production weight × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 1.83 % for yield loss rate, the number this scenario is built around.
  • At this operating point the engine returns -0.1 points for yield loss gap to target.
  • At this operating point the engine returns 950 count for lost product weight.
  • At this operating point the engine returns 52,000 count for total input or production weight.

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 %.
  • It computes the yield loss rate as lost product over total input, then compares that rate to your target to show the gap in percentage points. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Yield loss rate: 1.83 % (headline result)
