Dairy & Frozen Food Manufacturing worked example

Allergen Changeover Load at 12% verification and restart allowance: a worked example

This scenario runs the allergen changeover load calculation on the strong side: 12% verification and restart allowance, with every other input held at its documented default. Use it when allergen changeover load in dairy and frozen food manufacturing is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Allergen changeover cleaning tasks: 120 tasks (unchanged)
  • Changeover task completion rate: 12 tasks / hr (unchanged)
  • Verification and restart allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base allergen changeover hours = allergen changeover tasks รท changeover task completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required allergen changeover hours, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base allergen changeover hours.
  • At this operating point the engine returns 12 % for verification and restart allowance.
  • At this operating point the engine returns 12 pieces / min for changeover task completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where verification and restart allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it when planning a production sequence that crosses an allergen boundary, so the cleanout window is scheduled with realistic verification time built in. 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

  • Required allergen changeover hours: 11.2 hr (headline result)
  • Base allergen changeover hours: 10 hr
  • Verification and restart allowance: 12 %
  • Changeover task completion rate: 12 pieces / min
