Drying Capacity at 65% expected dryer uptime: a worked example

This worked example runs the drying capacity numbers for a tougher week than the baseline: 65% expected dryer uptime instead of the typical 90%. Estimate accepted precursor or CAM drying capacity after dryer cycles, uptime, and moisture-spec yield are considered.

The inputs for this scenario

  • Dry powder output per dryer cycle: 4 kg / cycle (held at the documented default)
  • Planned dryer cycles: 480 cycles (held at the documented default)
  • Expected dryer uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Moisture-spec first-pass yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross dryer output = dry powder output per dryer cycle × planned dryer cycles.
  • Accepted dry powder capacity works out to 1,211 kg at these inputs, and this is the headline figure for the scenario.
  • Gross dryer output works out to 1,920 kg at these inputs.
  • Drying capacity lost to downtime works out to 672 kg at these inputs.
  • Dry powder held for moisture rework works out to 37.44 kg at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected dryer uptime sits at 90% and the headline result is 1,676 kg, this scenario comes in 27.78% below the baseline at 1,211 kg.
  • Use it for dryer capacity planning, fleet sizing, or quantifying losses to downtime and moisture rework. 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.

Results at a glance

  • Accepted dry powder capacity: 1,211 kg (headline result)
  • Gross dryer output: 1,920 kg
  • Drying capacity lost to downtime: 672 kg
  • Dry powder held for moisture rework: 37.44 kg
