Total rack capacity does not show whether plates are ready when needed. Match demand and available stock over time.
Three data sets
- Run times and plates required per run.
- Ready plate stock at the start of the day.
- 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.
