Stay Fresh vs Harvest Right: Freeze Dryer Comparison (2026)

Shopping for a freeze dryer usually comes down to two names. Here is an honest, side-by-side comparison of Stay Fresh and Harvest Right machines — capacity, pumps, pricing, warranty and support — with every Harvest Right figure taken from harvestright.com as of October 3, 2026.

The lineups at a glance

The two lineups pair up by size: our 5-Shelf against the Harvest Right Medium, our 7-Shelf against their Large, our Mega against their X-Large — and our Large fills the 20–35 lb gap between their Large and X-Large. Harvest Right also sells a Small that we don't make an equivalent of.

Capacity and dimensions

Sorted smallest to largest by tray space. Stay Fresh machines are the highlighted rows.

Machine	Batch (lb fresh)	Tray space (in²)	Trays	Cabinet W×D×H (in)	Weight (lb)	Power
Harvest Right Small	6–10	434	4 @ 7.75×14	17.4×21.5×26.8	91	110V
Harvest Right Medium	10–15	675	5 @ 7.5×18	19×25×29	119	110V
Stay Fresh 5-Shelf	12–18	800	5 @ 8×20	20×26×31	165	110V, 15/20 A
Harvest Right Large	18–27	1,107	6 @ 9×20.5	21.3×27.5×31.3	143	110V, dedicated 15 A
Stay Fresh 7-Shelf	up to 18	1,120	7 @ 8×20	20×26×31	170	110V, 15/20 A
Stay Fresh Large	20–35	1,283	6 @ 9.5×22.5	22×29×34.5	224	110V, 20 A (NEMA 5-20)
Stay Fresh Mega	up to 50	1,733	6 @ 10.5×27.5	25.25×33.5×37.5	268	110V, 20 A (NEMA 5-20)
Harvest Right X-Large	40–50	2,251	7 @ 10.9×29.5	24.3×37.4×35.6	258	110V, dedicated 20 A (NEMA 5-20)

A note on our Standard cabinet: the 5-Shelf and 7-Shelf share one chamber — the 7-Shelf trades shelf spacing for two more trays, which suits herbs, greens, candy and other shallow loads. All Stay Fresh machines are air-cooled (intake left, exhaust right) and need 12 in. of side clearance.

Vacuum pumps

The biggest structural difference between the lineups. Harvest Right ships one Premier-class oil pump across all of its sizes (with an oil-free pump sold separately as an upgrade). Stay Fresh puts commercial-grade oil pumps on its larger machines as standard equipment:

• Premier oil pump — 7.2 CFM, 62 dB. Standard on the 5-Shelf and 7-Shelf.
• Commercial oil pump — 7.2 CFM, 0.4 kW, 54 dB, KF25 fitting, oil demister included. Optional on the 5- and 7-Shelf; standard on the Large.
• Mega Commercial pump — 10.2 CFM, 0.55 kW, 54 dB, with demister. Standard on the Mega.

Every current Stay Fresh machine ships with a standard KF25 vacuum flange — the fitting laboratories and vacuum shops already use — so hoses, clamps and gauges are stocked parts, not proprietary ones. And on every model, a motorized ball valve closes the vacuum line whenever the pump is not pulling, so pump oil cannot back-stream into the food chamber.

Pricing

Prices as of October 3, 2026. Harvest Right prices are their base (black) colors — stainless finishes run $400–500 more — and change often with promotions, so check their site for current numbers. Stay Fresh sells one finish, one price. Tap any Stay Fresh machine below to open its product page.

What you get as a Stay Fresh owner

• Lifetime technical support. Free for as long as you own the machine — no expiry date, no paid tier.
• Every machine batch-tested. Your freeze dryer runs a complete freeze-drying cycle before it ships — a real batch, not a function test.
• 60 days to change your mind. Twice the industry-standard return window.
• Ready on day one. Impulse sealer, 50 mylar bags, oxygen absorbers, trays, oil filter, and a 125-recipe book that lists the exact settings each recipe was developed with.
• Built to be repaired. Relays, compressor, PLC, touch screen and probes are serviceable parts, not sealed assemblies. We would rather sell you a relay in year six than a new freeze dryer.
• Nothing hidden before you buy. The complete user manual for every model — troubleshooting tables included — is a free download on its product page, next to published specs and a 4.93/5 rating from 164 reviews.
