Coffee, Tea, Roasting & Dry Goods Processing worked example

Changeover Cleaning Time at 29% allergen, flavor, and inspection allowance: a worked example in coffee, tea, roasting & dry goods processing

This scenario runs the changeover cleaning time calculation on the strong side: 29% allergen, flavor, and inspection allowance, with every other input held at its documented default. planning roaster, grinder, blender, or packaging changeovers

The inputs for this scenario

  • Changeover cleaning tasks to complete: 14 tasks (unchanged)
  • Cleaning tasks completed per hour: 3.5 tasks/hr (unchanged)
  • Allergen, flavor, and inspection allowance: 29 % (raised for this scenario; the documented default is 25)

Working through the calculation

  • Applying the documented formula (Base changeover cleaning time = changeover cleaning tasks รท cleaning tasks completed per hour) to the inputs above produces each figure below.
  • At this operating point the engine returns 5.16 hr for estimated changeover cleaning time, the number this scenario is built around.
  • At this operating point the engine returns 4 hr for base changeover cleaning time.
  • At this operating point the engine returns 29 % for allergen, flavor, and inspection allowance.
  • At this operating point the engine returns 3.5 pieces / min for cleaning tasks completed per hour.

How this compares with the baseline

  • Against the tool's baseline example, where allergen, flavor, and inspection allowance sits at 25% and the headline result is 5 hr, this scenario comes in 3.2% above the baseline at 5.16 hr.
  • Use it when sequencing a multi-SKU day, quoting changeover downtime to planning, or evaluating whether grouping flavors saves enough clean time to matter. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • estimated changeover cleaning time: 5.16 hr (headline result)
  • base changeover cleaning time: 4 hr
  • allergen, flavor, and inspection allowance: 29 %
