Freeze Drying Energy Cost Estimator
Freeze Drying Energy Cost Estimator
This tool deliberately does not supply an energy figure. Published values for energy per kilogram of water removed differ by close to an order of magnitude depending on what the scope includes, so the only honest version of this calculation uses a figure you have measured or been quoted.
Your Numbers
Take this straight from the Water-Load calculator.
Ask your supplier for this figure against your configuration, and ask what it includes: refrigeration, vacuum, shelf heating and defrost, or only part of that.
Your local utility cost per kilowatt-hour.
Total production cycles planned annually.
Target weight after moisture removal.
Estimation Results
Enter your figures and press Calculate Costs.
What This Does Not Include
- Steam, if your machine is steam heated. On a steam-heated build part of the heating load leaves the electricity bill and lands on the boiler.
- Labour, packaging, maintenance, defrost downtime and depreciation. Energy is one line of the total, not the total.
- Cooling water and compressed air for pneumatic valves.
