Is the Excalibur 3926TB 9-Tray hot enough for jerky?
Last reviewed September 2026.
The dial reaches the line — and USDA says the dial was never the whole question. The published range tops out at 165°F — above the USDA jerky line on paper. Excalibur's FAQ is unusually candid about what a dehydrator dial means: the setting reflects intended food temperature, and air temperature runs higher, because evaporation cools the food. That is exactly the mechanism USDA cites for why no dehydrator setting guarantees meat reaches 160°F before it dries — the dial number and the meat's internal temperature are different things. The oven pre-heat or post-heat step is USDA's answer, whatever the dial says.
The facts on file
| Verdict | 160°F+ published — Published max at or above 160°F — the oven step still applies |
| Temperature | 105–165°F, adjustable thermostat |
| Build | 600W · 9 trays, 15" × 15" — 15 sq ft published |
| The claim | “Adjustable to 165°F; Excalibur's own FAQ says the dial reflects food temperature, with air running hotter” |
Excalibur's own store no longer lists the 3926TB (checked 2026-10-08). The 10-tray dehydrator it does list is the Performance Series DH10SS, with its own record: Is the Excalibur Performance 10-Tray (DH10SS) hot enough for jerky? →

- Excalibur — 9-Tray 26-hour timer listing on amazon.com (ASIN B008OV4FD0), archived 2026-01-12: title “15 Square Feet … 600-Watts”, description “105 to 165 degrees F”. On 2026-10-08 the same ASIN shows a different unit (Select Series) and is currently unavailable, so the archived copy is the record

How to read this
USDA's jerky guidance sets the numbers — 160°F for meat, 165°F for poultry — and explains why the dehydrator can't be trusted to hit them on its own: evaporating moisture absorbs the heat, so the meat stays cooler than the air until most of the drying is done. Independent dial testing routinely finds units running 5–15°F below their setting. The answer on every row is the same and costs nothing: the oven step, before or after drying. And remember the dial is not the food's temperature.

Dehydrator Score indexes manufacturer-published temperature specs and marketing claims against the USDA jerky record, with attribution — we test nothing and give no safety advice. No dial setting substitutes for USDA's instruction: heat meat to 160°F (poultry 165°F) in an oven before dehydrating, or bake the finished jerky after — inside a dehydrator, evaporating moisture holds the meat below air temperature until it is already dry. If a maker publishes a spec or manual that changes a row, the page changes — the record wins.
