I have a "Au Naturel" (Model 700) Electric Food dehyrator and am trying to make dried tomatoes. Unfortunatly, the book is missing. Can anybody out there tell me what drying times they have listed for tomatoes?

Thanks, Jay

Tough One, But Read On


Couldn't find any user manuals specifically for the "Au Naturel" brand (are you in the UK?)

BUT, the key is the wattage ... your dehydrator is 700 watts as indicated by your model number.

The closest I could find is a Nesco brand 700 watt type.

It seems that in drying tomatoes (and fruits) is to check, check, check, so regardless of the brand, this is the key.


Here's the specific info and a link to the full owners manual which might prove useful:

Nesco FD-75PR Snackmaster® Pro 700 Watt Food Dehydrator


• Adjustable Thermostat. The adjustable thermostat allows you to dry different foods at proper temperatures (95º-160º F), providing the flexibility to produce the best drying results.
• New-Powerful Top Mounted Fan. Top mounted fan and 700 watts of drying power generate maximum speed and quality for dehydrating fruits, vegetables, and jerky. Helps dry food in hours, not days like other food dehydrators.
• Expandable unit comes with 5 trays, but is expandable to 12 trays with optional Add-A-Trays®.
• Patented Converga-Flow® drying system forces air down the exterior pressurized chamber (not through the trays). The hot air is forced horizontally across each individual tray, converging on the core for fast, even and nutritious drying. No flavor mixing and no need to rotate trays.

Wash. Then slice 3/8" circles or dip in boiling water to loosen skins for halves or quarters.

6-12 hrs.

Drying Temperature
Foods dried in the NESCO® American
Harvest Gardenmaster® dehydrator generally
dry more quickly than in other
models. Fruits, fruit rolls, and vegetables
should be dried at 130° to 140°F
(55° to 60°C). By drying foods in this
temperature range you will minimize
the loss of heat-sensitive vitamins A and
C. Because, all foods sweat when they
first begin to dry, the temperature may
be set higher than 140°F (60°C) during
the first couple of hours of drying. The
actual temperature of the food will
remain 15° to 20°F (6° to 8°C) lower
than the air temperature for the first
couple of hours.

Testing for Dryness
Food must be carefully monitored near
the end of the dehydration process to
prevent overdrying. Overdried foods
lose quality in texture, nutrition and
taste. To test for dryness, remove a piece
of food, allow it to cool, and feel with
your fingers to determine dryness.

• Fruits (more tomato-like as opposed to veges like peppers) should be pliable and leathery
with no pockets of moisture. To check
if fruit is dry, tear a piece in half and
watch for moisture beads along the
tear. If there aren’t any, it is sufficiently
dry for long term storage.

Onions and tomatoes are especially
prone to absorb moisture from the air
and should be packaged immediately
after removing from the dehydrator.

Thanks for the help.

No, Not in UK.
I'm currently in Wisconsin, but bought the unit in Connecticut, sometime in the mid-80's. No Adjustable thermostat or fan. Just a heater and shelves. Used to use it a lot, but moved to a "No Garden" location and it's been in storage for about ?? years.
Am trying it now, will have to leep watching and paying attention.

Good Deal

Okay Jay, at least it sounds like you can garden again!

Give it a go, I'm sure it'll work out.
