Ultrasonic Cleaning Time at 13% loading, dwell, and rinse allowance: a worked example

This worked example runs the ultrasonic cleaning time numbers for a tougher week than the baseline: 13% loading, dwell, and rinse allowance instead of the typical 18%. Estimate ultrasonic cleaning time from basket count, cleaning rate, and allowance for loading, dwell verification, and rinse handoff.

The inputs for this scenario

  • Baskets or fixtures to clean: 36 baskets (held at the documented default)
  • Ultrasonic throughput rate: 0.18 baskets / min (held at the documented default)
  • Loading, dwell, and rinse allowance: 13 % (the input this scenario stresses; the baseline uses 18)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base ultrasonic cleaning time = baskets or fixtures to clean รท ultrasonic cleaning completion rate.
  • Required ultrasonic cleaning time works out to 226 min at these inputs, and this is the headline figure for the scenario.
  • Base ultrasonic cleaning time works out to 200 min at these inputs.
  • Loading and dwell allowance works out to 13 % at these inputs.
  • Ultrasonic cleaning completion rate works out to 0.18 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where loading, dwell, and rinse allowance sits at 18% and the headline result is 236 min, this scenario comes in 4.24% below the baseline at 226 min.
  • Use it when scheduling ultrasonic tanks, sizing cleaning capacity for a shift, or quoting cleaning lead time. 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 ultrasonic cleaning time: 226 min (headline result)
  • Base ultrasonic cleaning time: 200 min
  • Loading and dwell allowance: 13 %
  • Ultrasonic cleaning completion rate: 0.18 pieces / min

Run it with your numbers
