Why the Excalibur Dominates the Dehydrator Market
The 3926T has been the standard recommendation for serious home food preservation for decades. The key differentiator is horizontal airflow: a rear-mounted fan pushes air across all 9 trays simultaneously, delivering uniform drying without tray rotation. Cheap circular dehydrators with top or bottom-mounted fans create hot and cold spots that require constant tray rotation to compensate.
At 600W for 15 sq ft of drying surface, it’s also efficient — comparable circular units often draw 1,000W+ for less surface area.
Drying Performance by Food Type
| Food | Temp | Time | Result |
|---|---|---|---|
| Apple slices (1/4″ thick) | 135°F | 7–8 hrs | Perfectly pliable, no wet spots |
| Beef jerky (1/4″ strips, marinated) | 160°F | 4–5 hrs | Firm, ~30% weight remaining |
| Tomatoes (halved) | 145°F | 10–12 hrs | Sun-dried quality, consistent across all trays |
| Kale chips | 125°F | 3–4 hrs | Crispy, even — no burning on lower trays |
| Herbs (basil, oregano) | 105°F | 2–3 hrs | Fully dried, color and aroma preserved |
| Banana slices | 135°F | 8–9 hrs | Chewy texture, no moisture pockets |
At 160°F for 4+ hours, the Excalibur meets USDA safe temperature guidelines for jerky without pre-cooking the meat — a requirement many cheaper dehydrators can’t meet because they can’t reliably sustain 160°F.
The Horizontal Airflow Advantage
In direct comparison testing against a circular vertical-flow dehydrator of the same wattage, the circular unit required tray rotation every 2 hours to avoid uneven drying. The Excalibur required zero tray rotation across all test foods. Temperature variance across all 9 trays in our test: ±3°F at steady state — exceptional uniformity.
Off-Grid Energy Use
Solar Compatibility
The Excalibur at 600W runs fine on a 1,500W or larger inverter. A 2,000Wh battery bank can run a full 8-hour drying batch with energy to spare — useful to know if you’re dehydrating from solar power. Energy cost per batch: 600W × 8 hrs = 4.8 kWh ≈ $0.58 at grid rates.
Pros and Cons

Final Verdict
Verdict: Top Pick
The Excalibur 3926T is the best food dehydrator for anyone serious about food preservation. The horizontal airflow and 15 sq ft of drying area make it a genuine homestead tool. If you’re processing garden harvests, making jerky, or building a long-term food storage system, this is the dehydrator to buy.
