The Cosori Stainless Steel Dehydrator dries reliably, with even heat distribution and fast drying times. Reviewers praised the quiet 46.1 dB operation and the stainless steel trays that clean easily in the dishwasher. Users noted the unit ships with too few mesh sheets and that the stainless steel trays can be sticky. It runs a 600-watt motor with 6 trays and 936 sq. in. of total drying space, plus automatic shut-off. Beginners and home users who want a value-priced alternative to higher-end models like Excalibur are the fit, though several recommend buying extra mesh sheets.
Full review
Six stainless trays and 936 square inches
The trays are the reason to choose this over a stacking dehydrator. They are stainless wire rather than plastic, they slide in and out of a hinged front door, and BackpackingChef notes they lie flat in a kitchen sink for soaking and go in the dishwasher afterwards. Across six of them that is 936 square inches of drying space.
The cabinet measures 17.8 by 13.4 by 12.4 inches with a glass window in the door, and the rear-mounted fan and heating element push air horizontally across the trays. The Salty Pot points out that this differs from the bottom-mounted fans older machines use, and it is why nothing needs rotating mid-run. There is roughly 1.5 inches of clearance between trays, enough for bulkier produce without pulling a shelf.
Temperature holds within three degrees
BackpackingChef measured variance of under 3 degrees across a range running from 95°F to 165°F, which is the specification that matters most for food safety and for anything that needs a low, steady temperature. The same reviewer, replacing a twelve-year-old Excalibur, reported drying times comparable to that machine despite the Cosori's smaller 600-watt element, and ran it successfully on rice, potatoes, fruit, fruit leather, and several stews and sauces.
The Purposeful Pantry rates it among the quietest machines available at 46.1 dB, quiet enough to run in a laundry room or near a dining table without intruding. The timer goes to 48 hours in 30-minute increments with automatic shut-off at the end.
One mesh sheet is not enough
The box contains a single mesh sheet and one plastic fruit-roll tray, and both fall short. The Purposeful Pantry describes the mesh sheet as too small and too rigid, and BackpackingChef found the fruit-roll tray is not non-stick and works poorly for leather. Anyone drying small items such as corn or peas needs more mesh than ships with the machine, so budget for extra sheets as part of the purchase.
The stainless trays themselves have a downside that the marketing does not mention: The Purposeful Pantry found them very sticky and hard to clean with anything moisture-laden, and recommends mesh or parchment on most projects. Which means the accessory you have to buy is the one that makes the headline feature usable.
It runs hot on the outside, and the timer resets
Two behaviours catch owners out. Above about 145°F the top, sides and back get hot to the touch, so BackpackingChef suggests standing it on a glass board rather than directly on a worktop. And pressing stop mid-run resets the timer to zero rather than pausing it, which The Purposeful Pantry flagged as a design flaw and it is exactly the wrong behaviour on a machine you are meant to check on.
The more serious mark against it is a reliability report: The Purposeful Pantry experienced an overheating event on the larger ten-tray model where the protection did not do its job, ended up removing the machine from their home, and got no useful response from customer service. It is one account rather than a pattern, but it is the kind of account worth weighing on an appliance that runs unattended overnight.
The value argument against an Excalibur
BackpackingChef puts the price gap at $210 less than a five-tray Excalibur, with drying times that matched their old machine and more trays than the comparison model. The Salty Pot's read on the brand is that it is affordable and of decent quality, and the included recipe book gives a beginner somewhere to start.
So the trade is clear enough. This is the machine for someone dehydrating occasionally who values easy cleanup and quiet operation and does not want to spend Excalibur money. Someone running batches constantly, or drying a lot of small items, will spend more on accessories and should think harder about the reliability reports before committing.
Strengths
- +Dries food evenly from top to bottom with no need to rotate trays
- +Dries food fast with 600 watts of power and consistent temperature maintenance
- +Quiet operation at 46.1 dB, suitable for kitchen use
- +Stainless steel trays fit flat in sink for cleaning and are dishwasher safe
Watch-outs
- −Unit comes with only 1 mesh dehydrator sheet that is too small and rigid
- −Stainless steel trays can be sticky and hard to clean with moisture-laden foods
How it compares
Unlike the Cosori Pioneer 5-Tray model, the Cosori Stainless Steel Dehydrator offers dishwasher-safe stainless steel trays that fit flat in the sink, making cleaning more convenient. However, it shares the same issue of insufficient mesh sheets and lacks the Pioneer's slightly better temperature variance control. Compared to the Magic Mill 7 Tray Pro, it has fewer trays and less precise temperature controls, though it does offer quieter operation.
Rating sources
“Dries food evenly from top to bottom with no need to rotate trays. Dries food fast. Drying times are comparable to an Excalibur dehydrator.”
“Cosori food dehydrators are a great brand of dehydrators that will make food preservation through drying food easy and fun!”
“I am a big fan of the Cosori brand because their products are affordable and of great quality. But what about this product? Will it live up to the hype and be worth investing your money in?”
“I think it's kind of stingy for a company not to not to at least give you like three of these piece at least to fill up half of your machine because you're going to need these anyway.”
