Industrial Enzymes & Bio-Ingredients worked example

Drying Energy with dryer connected load of 460 kW: a worked example in industrial enzymes & bio-ingredients

This scenario runs the drying energy calculation on the strong side: dryer connected load of 460 kW, with every other input held at its documented default. Use it when comparing spray drying, tray drying, fluid bed drying, or concentration conditions for finished ingredient cost.

The inputs for this scenario

  • Dryer connected load: 460 kW (raised for this scenario; the documented default is 185)
  • Drying runtime: 9 hr (unchanged)
  • Blended electricity cost: 0.13 $ / kWh (unchanged)
  • Accepted dried product output: 1,450 kg (unchanged)

Working through the calculation

  • Applying the documented formula (Total drying energy cost = dryer connected load × drying runtime × blended electricity cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,140 kWh for drying energy used, the number this scenario is built around.
  • At this operating point the engine returns 538 $ for total drying energy cost.
  • At this operating point the engine returns 0.37 $ / piece for drying energy cost per kg.
  • At this operating point the engine returns 59.8 $ / hr for hourly drying energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where dryer connected load sits at 185 kW and the headline result is 1,665 kWh, this scenario comes in 149% above the baseline at 4,140 kWh.
  • Use it when costing a drying step, comparing dryers, or quantifying the energy penalty of off-spec output and rework. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
