The Best Stainless Steel (Plastic-Free Tray) Food Dehydrators of 2026

True stainless versus chrome plating

Some dehydrators with metal-looking trays use chrome-plated steel. Excalibur's cheaper Select line is an example. If avoiding coatings is the goal, look for trays described as stainless steel, ideally with a grade such as 304.

How much of the chamber is metal

Stainless trays can sit inside a plastic housing, with plastic doors and drip trays. Check the housing, door and drip pan. Of our picks, the LEM documents the most metal, the Cosori and Excalibur models use stainless bodies with glass doors, and Magic Mill doesn't say what its housing is made of.

Airflow

A rear horizontal fan moves air across every tray, so you don't need to rotate them. Stacked, bottom-fan designs usually dry unevenly. All five picks use rear horizontal fans.

Temperature range and accuracy

Jerky needs the top of the range, so look for 160°F or more. Accuracy matters too: TechGearLab saw a Magic Mill read 155°F at a 165°F setting, while the Cosori 6-tray stayed within about 3°F. A low end around 85 to 95°F helps with herbs and delicate foods.

Capacity and footprint

Six trays suit a typical household. Ten-tray units offer 10 to 16 sq ft but weigh 32 to 36 lb and need permanent space. Think about where it will live before buying.

Cleaning and timer

Bare metal trays can hold sticky food. Parchment sheets help, as do dishwasher-safe trays. A long timer with auto-shutoff lets you run overnight; the Excalibur offers 80 hours, the Cosori models 48.

The main benefit of these dehydrators is that your food touches stainless steel instead of plastic. Stainless is non-coated, doesn't scratch off like some nonstick finishes, and tolerates heat and acidic foods such as citrus and tomatoes.

Check the accessories. The Cosori 6-tray's mesh screen and fruit-roll sheet are non-metal, and Cosori doesn't say what they're made of. Parchment paper is a plastic-free alternative for fruit leather and small items. The same applies to the Cosori 10-tray's extras. Magic Mill says its materials are BPA-free but doesn't say which parts are plastic.

Cosori's pages carry a California Prop 65 warning for lead. That is a disclosure, not a measured exposure. We found no CPSC dehydrator recall for Cosori; its 2023 recall involved air fryers. Excalibur's 2019 recall involved different EZ DRY units, and LEM's recalls covered older 5-tray plastic models.

Power use varies. The Cosori 6-tray is rated at 600 W, among the lower draws for a six-tray unit; the ten-tray models draw 800 to 1000 W. Excalibur and Magic Mill sell replacement trays, which helps you keep a unit for years.

Excalibur Select DH10SCSS13: a similar ten-tray box, but Select-series trays are chrome-plated rather than stainless. Choose the Performance DH10SSSS13 if you want true stainless.

Nesco FD-7SSD: dropped because its Amazon listing details didn't match the model and it was out of stock. Its included drip tray and mesh sheet are plastic.

Magic Mill MFD-9100: Food Network endorsed it for fruits and vegetables, but Magic Mill doesn't disclose its housing material, and it isn't listed on Amazon.

Cosori CFD-P501-SUS: sold out at Cosori, with no independent testing and conflicting maximum-temperature specs.

Excalibur DH06SSSS13 and EXC10EL: no longer available.

Tribest Sedona SDE-S6780-B: a plastic body, so not a plastic-free chamber, and it costs far more.

STX Dehydra and Elite Gourmet models: owner-reported heater failures or plastic walls and lids, along with stacked designs that need tray rotation.

Are stainless steel food dehydrators really plastic-free?

The trays are, but the rest varies. The LEM documents a stainless housing, trays and drip pan. The Cosori and Excalibur models have stainless bodies with glass doors, though accessories may be non-metal. Check the housing, door and included sheets.

Can I make jerky in these?

Yes. The Cosori models and the Excalibur reach 165°F, and the LEM reaches 176°F. Follow USDA guidance on preheating or cooking meat for jerky. The Cosori 6-tray had weak dried-meat results in TechGearLab's test, so use parchment and check doneness.

Do I need to rotate the trays?

No. All five picks use a rear horizontal fan, so air moves across every tray. This is a main reason to choose a box design over a stacked one.

Are the trays dishwasher-safe?

Cosori, LEM and Magic Mill list stainless trays as dishwasher-safe, as does Excalibur's own page. One retailer says to hand-wash the Excalibur, so follow the manual. Parchment reduces sticking either way.

Which should I buy if I only dry occasionally?

The Cosori 6-tray. It has enough capacity for typical use, a mainstream price, and the best independent results of the group.

Is a bigger dehydrator worth it?

Only if you dry large batches often. The ten-tray units weigh 32 to 36 lb and need room to live. Gardeners and hunters will use the capacity; most households won't.

For most people, the Cosori 6-tray is the one to buy: stainless trays, stainless body, glass door, accurate temperatures and the strongest independent endorsement. Step up to the Cosori 10-tray if you dry in volume, the Excalibur Performance if you want the longest timer and a three-year warranty, and the LEM if the most metal in the chamber matters most. The Magic Mill is a reasonable mid-size choice if your main concern is that food touches only stainless. Whichever you pick, line the trays with parchment for sticky foods and expect to wash them after each batch.
