A freeze dryer pays for itself when the money saved per batch (store price minus your running cost) adds up to the machine price.
Estimates for planning, not food-safety advice. Freeze-drying does not kill bacteria — follow tested food-safety guidance.
A freeze dryer pays for itself when the money saved per batch (store price of the same food minus your cost per batch) has added up to the machine and accessories price. With the example values — $3,150 total, $40 store value and $8.46 cost per batch, 4 batches a month — that takes about 100 batches, or about 25 months.
These are example values, not prices of any specific machine — use your own.
