Coffee, Tea, Roasting & Dry Goods Processing worked example

Moisture Loss at 7.92% target moisture-loss percentage: a worked example in coffee, tea, roasting & dry goods processing

This worked example runs the moisture loss numbers for a tougher week than the baseline: 7.92% target moisture-loss percentage instead of the typical 11%. Calculate moisture loss from water weight lost during roasting, drying, or dry goods processing compared with starting product weight.

The inputs for this scenario

  • Moisture weight removed in roast/dry: 12 lb (held at the documented default)
  • Starting wet or green product weight: 100 lb (held at the documented default)
  • Target moisture-loss percentage: 7.92 % (the input this scenario stresses; the baseline uses 11)

Working through the calculation

  • The calculation starts from the formula this tool documents: Moisture Loss = moisture weight removed ÷ starting wet or green product weight × 100.
  • moisture loss works out to 12 % at these inputs, and this is the headline figure for the scenario.
  • moisture loss gap to target works out to -4.08 points at these inputs.
  • moisture weight removed works out to 12 count at these inputs.
  • starting wet or green product weight works out to 100 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target moisture-loss percentage sits at 11% and the headline result is 12 %, this scenario lands almost exactly on the baseline at 12 %.
  • Use it after roasting or drying when you have a verified before-and-after weight, or when dialing in a dryer to a moisture-content spec. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
