Cooling Tunnel Capacity at 99% cooling tunnel uptime: a worked example

What does the result look like when cooling tunnel uptime reaches 99%? The full calculation is worked below with real intermediate numbers. a confectionery, bakery, or snack line needs to verify cooling capacity before increasing oven, enrober, depositor, or packaging rates

The inputs for this scenario

  • Units loaded per cooling cycle: 1,200 pieces/cycle (unchanged)
  • Available cooling cycles in the period: 14 cycles (unchanged)
  • Cooling tunnel uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass cooling yield: 98 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross cooling tunnel capacity = units loaded per cycle × available cooling cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 16,299 pieces for good cooled output capacity, the number this scenario is built around.
  • At this operating point the engine returns 16,800 pieces for gross cooling tunnel capacity.
  • At this operating point the engine returns 168 pieces for units lost to cooling downtime.
  • At this operating point the engine returns 333 pieces for units lost to cooling defects.

How this compares with the baseline

  • Against the tool's baseline example, where cooling tunnel uptime sits at 90% and the headline result is 14,818 pieces, this scenario comes in 10% above the baseline at 16,299 pieces.
  • A figure at this level is achievable when cooling tunnel uptime is genuinely sustained, not just peaked for a shift. It assumes a fixed load per cycle and steady belt conditions; in reality ambient humidity, product mass, and belt speed all shift cooling yield, so treat the result as a planning estimate rather than a guarantee.

Results at a glance

  • Good cooled output capacity: 16,299 pieces (headline result)
  • Gross cooling tunnel capacity: 16,800 pieces
  • Units lost to cooling downtime: 168 pieces
  • Units lost to cooling defects: 333 pieces
