Allergen Changeover Load at 7.2% verification and restart allowance: a worked example

This worked example runs the allergen changeover load numbers for a tougher week than the baseline: 7.2% verification and restart allowance instead of the typical 10%. Estimate hours required for allergen changeover cleaning, verification, and restart on dairy or frozen food lines.

The inputs for this scenario

  • Allergen changeover cleaning tasks: 120 tasks (held at the documented default)
  • Changeover task completion rate: 12 tasks / hr (held at the documented default)
  • Verification and restart allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base allergen changeover hours = allergen changeover tasks รท changeover task completion rate.
  • Required allergen changeover hours works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base allergen changeover hours works out to 10 hr at these inputs.
  • Verification and restart allowance works out to 7.2 % at these inputs.
  • Changeover task completion rate works out to 12 pieces / min at these inputs.

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 2.55% below the baseline at 10.72 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. 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

  • Required allergen changeover hours: 10.72 hr (headline result)
  • Base allergen changeover hours: 10 hr
  • Verification and restart allowance: 7.2 %
  • Changeover task completion rate: 12 pieces / min
