A freeze dryer costs between $2,699 and $13,495 to buy, roughly $6 in electricity per cycle, and about $0.72 per sealed bag in packaging. Here is the whole bill, itemised, so you can work out whether it pays for you.
The purchase
Entry prices across the seven machines we cover run from $2,699 for the Stay Fresh with Premier Pump to $13,495 for the Blue Alpine XL Commercial. The useful thing to compare is not the sticker but what arrives in the box: the Blue Alpine Medium at $2,995 includes an impulse sealer, five silicone mats, 50 mylar bags, 50 oxygen absorbers and pump oil, which is roughly $190 of accessories you would otherwise order separately.
Electricity, per cycle
This is the number people search for and almost nobody publishes. Manufacturers state average power draw, so the arithmetic is straightforward.
| Blue Alpine Medium | Blue Alpine Large | |
|---|---|---|
| Average draw | 1,080W | 1,440W |
| Published cycle | 12–20 h | 12–20 h |
| Energy, 20-hour run | 21.6 kWh | 28.8 kWh |
| At $0.15/kWh | $3.24 | $4.32 |
| At $0.28/kWh | $6.05 | $8.06 |
| At $0.40/kWh | $8.64 | $11.52 |
Packaging, per bag
Consumables are the cost that never stops, and they are also the cost that decides whether the food actually lasts. At Blue Alpine’s own prices, mylar bags with matched absorbers are $35.99 for 50 — about $0.72 per sealed gallon bag. Absorbers on their own are $7.99 per 50, or $0.16 each.
Do not economise here. A $0.16 absorber is what separates a twenty-year bag from an eighteen-month one, and skipping it wastes the $6 of electricity you just spent.
Maintenance
Oil-filled pumps need oil changes. Blue Alpine owners report the company specifying every 3 to 4 cycles, which is markedly shorter than the 25 to 30 cycles quoted elsewhere in the industry; at roughly $46 for a litre and filter kit, that interval is worth confirming with the manufacturer before you budget. An oil-free pump removes the chore entirely and is worth asking about if you plan to run the machine weekly.
So does it pay?
Work it the other way round. Commercially packaged freeze-dried food runs roughly $6 to $12 per finished pound. A Blue Alpine Medium turns 10 lb of fresh food into something like 1.5 to 2.5 lb finished, at about $6 of electricity plus $2 of packaging. If you are preserving food you already have — a garden glut, a bulk meat buy, food that would otherwise go in the bin — the machine is paying for itself against waste, not against shop prices, and that maths is much more favourable.
If you would be buying food specifically to freeze-dry it, the break-even is a long way out and you should be honest with yourself about how often the machine will actually run.
