Total rack capacity does not show whether plates are ready when needed. Match demand and available stock over time.

Three data sets

  1. Run times and plates required per run.
  2. Ready plate stock at the start of the day.
  3. Counts and entry times for plates put into freezing.

Find the time-based gap. For each departure, subtract prior demand from ready stock. For example, demand of 40 and 32 ready plates gives an initial gap of 8; account for entries and earlier runs too.

Compare across the month

Review busy days separately and record the gap in the same time window. A daily total can hide a queue during the day.

Limits of a capacity decision

One shortfall does not prove a new rack is needed. Review layout, workflow and readiness timing; check model capacity and cycle limits in the technical manual.

Energy record

If freezing hours change, compare relevant consumption and tariff records separately. Do not assume an energy saving resolves a capacity gap.

Closed days

Record stock at the first shift after a holiday or weekend. Match return-day demand and prior entries to see whether a gap occurs only on those days.
