Excalibur 3926TB 9-Tray Food Dehydrator Review: 15 Square Feet of Quiet, Even Drying
The Excalibur 3926TB is the box-shaped 9-tray dehydrator that food preservers, jerky makers, and raw-foodies have argued is worth its premium for nearly two decades. After looking at how it's specced, what owners report, and how it stacks up against newer stacked-tray competitors, the short answer is: yes, if you actually plan to dry food in volume. If you'll fire it up twice a year for a half-tray of apple slices, you don't need this much machine.
What you're actually buying
The 3926TB is a black, square-bodied dehydrator measuring roughly 17 x 19 x 12.5 inches, holding 9 plastic trays that slide in and out like oven racks. Total drying surface is 15 square feet — substantially more than the round, stacked-tray dehydrators that dominate the under-$100 segment. A 600-watt heating element and fan sit at the back of the cabinet, blowing horizontally across each tray.
Key specs Excalibur publishes for this model: adjustable thermostat from 105°F to 165°F, a 26-hour timer with automatic shutoff, and a fully assembled-in-USA build. The 3926TB is the timer-equipped sibling of the older 3900 and 3926T lines. Trays are BPA-free plastic, dishwasher-rated (top rack), and you can pull trays out to make room for taller items like whole pineapple rings or short jerky-rack setups.
Performance and real-world use
The horizontal-airflow design — Excalibur calls it "Parallexx" — is the real reason this dehydrator has held its reputation. Because heated air moves across each tray rather than up through a stack, you don't have to rotate trays mid-cycle to get even drying, and moisture released from food at the bottom doesn't have to pass through everything above it. In practice, owners report being able to load all 9 trays with jerky, fruit leather, or herbs and pull them off at roughly the same doneness.
The 26-hour timer matters more than it sounds. A lot of dehydrator runs are 8–16 hours; without a timer, you're either babysitting the machine or running it longer than ideal. The low end of the thermostat range (105°F) is also notable — that's the cutoff most raw-food and probiotic enthusiasts look for, and a lot of cheaper dehydrators bottom out around 95°F or 115°F.
Noise is moderate. The fan is louder than a quiet refrigerator and quieter than a microwave; most owners say they can run it in a kitchen overnight without it being disruptive, but it's not silent. The plastic trays and door feel utilitarian rather than premium — this is not a beautiful machine, and it does take up real counter space.
- Horizontal airflow gives genuinely even drying across all 9 trays without rotation
- Full 105°F–165°F thermostat range covers raw-food, herbs, jerky, and fruit leather
- 26-hour timer with auto shutoff handles long runs without supervision
- 15 sq ft of drying space — enough for bulk jerky batches, full harvests, or large fruit hauls
- Made in USA, with replacement parts and trays readily available
- Trays can be removed to fit tall items or jerky cannon racks
- Footprint is big — roughly 17 x 19 inches of counter or pantry space
- Plastic body and trays feel cheap relative to the price
- No internal light or window to check progress; you have to open the door
- Fan is audible enough that it's noticeable in an open kitchen
- Twice or three times the price of the round stacked-tray dehydrators most beginners start with
This is the right machine if you actually batch-dehydrate: hunters making jerky in bulk, gardeners drying full herb or pepper harvests, raw-food cooks who want temperatures low enough to preserve enzymes, or anyone who's outgrown a $60 stacked round unit and is tired of rotating trays. The 15 sq ft and timer combination turns dehydrating from a fussy hands-on task into something close to "load and walk away."
If you dehydrate once or twice a year — a tray of apple chips, occasional homemade fruit roll-ups — the 3926TB is overkill and the round stacked-tray competitors at a third of the price will do fine. It's also a bad fit for small kitchens; this is not a machine you tuck behind the coffee maker. And if a touchscreen, app, or digital readout matters to you, look at newer digital Excalibur models or the Cosori Premium line instead.
The Excalibur 3926TB has earned its long-running reputation by getting the fundamentals right: even airflow, a useful temperature range, a real timer, and enough capacity to make dehydrating worth doing. It's not stylish and it's not cheap, but it's the dehydrator most serious home users end up at eventually. Rating: 4.5/5.
