Batch to Annual Output Converter
Batch to Annual Output Converter
Rungs 7 to 10 of the Water-Load Ladder. Cycle time is the number that turns a batch weight into an annual figure, and it is the number most quotations leave out.
Your Cycle
Total wet weight of raw material prepared for processing.
Freeze, vacuum draw-down, primary drying, secondary drying, unloading and defrost. Establish it by trial on your own product.
Number of days the facility is running full production shifts.
Take this from the Water-Load calculator rather than guessing. High-moisture fruit typically lands in single digits.
Calculation Results
Enter your figures and press Calculate Output.
Reading the Result
- Two plants with the same chamber and different cycle times end up with very different annual output. The chamber is not the variable.
- Shaving an hour off changeover and defrost repeats on every batch, so it compounds across the year.
- If the annual figure falls short, compare the cost of cutting cycle time against the cost of a larger chamber before deciding.
