THE NUMBERS, EXPLAINED
How to use this calculator.
Long-run average throughput, allowing fractional expected trays. Excludes food process validation.
Start with your inputs
Enter tray cavities per cycle, cycle time (seconds), downtime per scheduled hour (minutes), reject rate (%). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Tray cavities per cycle | 4 |
| Cycle time (seconds) | 20 |
| Downtime per scheduled hour (minutes) | 10 |
| Reject rate (%) | 4 |
A worked example
With the example inputs above, cycles per scheduled hour is 150. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Cycles per scheduled hour | 150 |
| Gross trays per scheduled hour | 600 |
| Expected saleable trays per hour | 576 |
How this is calculated
Cycles per scheduled hour
Divide operating seconds by measured cycle duration.
Gross trays per scheduled hour
Multiply cycles by tray cavities.
Expected saleable trays per hour
Apply saleable yield to gross trays.
Symbols and units
- a
- Tray cavities per cycle
- b
- Cycle time (seconds)
- c
- Downtime per scheduled hour (minutes)
- d
- Reject rate (%)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Long-run average throughput, allowing fractional expected trays. Excludes food process validation.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Cycles per scheduled hour; Gross trays per scheduled hour; Expected saleable trays per hour. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Long-run average throughput, allowing fractional expected trays. Excludes food process validation.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
