Tank Turnover at 92% tank utilization: a worked example

What does the result look like when tank utilization reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when a planner is sizing how many recipes can rotate through one tank in a shift, or whether a second mixer is needed to hit demand.

The inputs for this scenario

  • Volume processed per shift: 2,400 gal (unchanged)
  • Mixer operating hours: 8 hr (unchanged)
  • Tank utilization: 92 % (raised for this scenario; the documented default is 80)

Working through the calculation

  • Applying the documented formula (Raw tank turnover = volume processed per shift รท mixer operating hours) to the inputs above produces each figure below.
  • At this operating point the engine returns 276 turns / hr for effective throughput, the number this scenario is built around.
  • At this operating point the engine returns 300 turns / hr for raw throughput.
  • At this operating point the engine returns 92 % for efficiency.
  • At this operating point the engine returns 8 hr for runtime.

How this compares with the baseline

  • Against the tool's baseline example, where tank utilization sits at 80% and the headline result is 240 turns / hr, this scenario comes in 15% above the baseline at 276 turns / hr.
  • A figure at this level is achievable when tank utilization is genuinely sustained, not just peaked for a shift. It treats utilization as a flat multiplier and ignores changeover, CIP, and heat-up dead time, so true vessel availability is lower than the runtime hours you enter.

  • Effective throughput: 276 turns / hr (headline result)
  • Raw throughput: 300 turns / hr
  • Efficiency: 92 %
  • Runtime: 8 hr
