■To disconnect, turn the control to “off” before removing
the plug from the outlet.
■To reduce the hazards of potential shock, the
dehydrator has a polarized plug (one blade is wider
than the other), which will fit only one way in a
polarized outlet. If the plug does not fit, contact a
qualified electrician for assistance. Do not attempt to
defeat this safety feature.
■Do not clean with metal scrubbing pads. Pieces can
break off the pad and short-circuit electrical parts,
creating a possibility of an electrical shock and
damaging the unit.
■To protect against electrical shock, do not immerse
plug, cord or motor base in water or any other liquid.
■It is recommended that you do not use an extension
cord with this dehydrator. However, if one is used, it
must have a rating equal to or exceeding the rating of
this appliance.
■This dehydrator is for household use only.
■This dehydrator should not be used for other than its
intended use.
■If you suspect your food is contaminated, do not eat it.

Food Dehydrator
BEFORE FIRST USE
1. Remove the base unit, 5 food trays, 2 tray liners (for
making fruit leather), and 1 mesh tray (for drying
finely chopped foods and herbs).
2. Wash trays, liners and cover in warm soapy water.
Rinse well. (They can also be washed in the top rack
of the dishwasher.)
3. Wash the outside of the base unit with a moist sponge
and mild detergent. Do not spill water or other liquids
in openings. Do not immerse the base unit in water or
any other liquid.
DRYING/SELECTING FOODS TO DRY
Foods to dry should be in prime condition. Because sugar
is not added, as it is to canned foods, dried unripe fruits
may have a flat, often bitter taste. Tree-ripened fruits have
the highest natural sugar and best flavor for drying.
Vegetables should be fresh and tender when dried. Avoid
overripe fruits and vegetables, and cut away any bruised
or spoiled portions. Remember that if it’s perfect for
eating, it will be best for drying.

HOW TO OPERATE THE
DENI FOOD DEHYDRATOR
1. Place the base unit on a counter top or other suitable
firm surface. Plug the unit into a proper wall outlet.
Be certain that the outlet voltage corresponds with the
voltage marked on the base unit.
2. Prepare the food, according to its type, as indicated in
the drying charts on the following pages.
3. Preheat the dehydrator by turning it on 5-10 minutes
before loading the first tray.
4. Arrange food to dry on each of the trays. Remember
that it is the hot air circulation that dries the food, so
do not overload the trays and never overlap the food.
Stack trays with prepared food and place on the base
pan. Place the cover in position.
5. Dry for the time period suggested on the charts.
Check food frequently (every 1/2 hour) near the end
of the drying time and remove individual pieces as
they become dry. When foods are all the same size
and thickness, they will dry evenly and at the same
rate.

7100 Instructions sgle pg 6/18/01 9:46 AM Page 6
PREPARING FOODS TO DRY
Apples, pears, peaches and apricots are frequently
pretreated to slow the loss of vitamins A and C and also to
prevent browning. All fruits and vegetables should be
thoroughly washed to remove dirt, bacteria and insect
larvae. Fruits and vegetables may be peeled. If the peels
are left on the fruit, they will add extra nutrition, however,
the peels may be tough and grainy when dried. Try both
ways and then decide for yourself. Remove any stems or
pits and core when necessary. Vegetables should be steamblanched to retard “enzyme action” which will result in
undesirable flavor changes in stored dried vegetables.
Blanching also dries more quickly and reconstitutes better.
Remove as much excess water as possible before starting.
Note: The ventable lid can be adjusted by opening the vent
on the lid allowing good air circulation and moisture evacuation. The closed position causes faster drying. We recommend that the vent remain fully open. If you prefer the
closed position during the dehydration process, it is suggested to open the vent during the beginning of the dehydration
process to allow moisture to escape and then close the vent.
Afterwards, open the vent 10 minutes, every 4 hours.
DRYING TIME
There are so many variables that it is difficult to estimate
exact times for drying. Variables include the outside temperatures and humidity, how full the dehydrator is loaded,
and the type and thickness of foods to be dried. Here are
some guidelines:
Fruits should be pliable and leathery with no pockets of
moisture. There is a tendency to over dry fruits until they
are tough and hard. Over dried fruits do not store as well
as properly dried fruits, do not taste as good and have less
nutritional value. Properly dried fruits should contain about
15-18% moisture, and feel soft but not squishy. Vegetables
should be tough or brittle. They store best when they contain about 5% moisture.

STORAGE
Packaging
DRIED FOODS MUST BE PROPERLY PACKAGED IN ORDER
TO KEEP WELL. Package your dried foods in freezer plastic
bags, squeezing out as much air as possible. We recommend using one of the several models of Deni Freshlock®
vacuum sealers or vacuum canisters. Store the plastic bags
inside of airtight metal, plastic or glass containers. Storing
foods in rigid containers without first putting them into
freezer bags exposes the dried foods to air. Call
1-800-DENI-VAC for more information about vacuum
packaging. Vacuum sealing will greatly extend shelf life
2-3 times longer than conventional methods.
Storage Containers
Store properly packaged dried foods in a cool, dark place.
The cooler the food is kept, the longer the optimal quality
will be maintained. For every 18°F drop in temperature, the
shelf life increases 2-3 times. If you have room in a
refrigerator or freezer, keep your dried foods there.
Otherwise, find the coolest place in your home to store
dried foods. Light also causes the quality and nutritive value
to deteriorate. Keep dried foods in the dark or in opaque
6
containers.
SHELF LIFE
Fruits have a naturally high sugar and acid content, which
will allow them to dry well and store for longer periods of
time than vegetables. When properly packaged and stored
at room temperature or below (70°F or less), most fruits will
maintain a high quality and nutritional value for up to a
year. Most vegetables are best when consumed within six
months.
Note: Fruits and vegetables kept beyond the recommended
time may not be as nutritious or taste as good, but will not
spoil unless the packaging is no longer intact.
HOW TO CLEAN THE DEHYDRATOR
1. Prior to any operation, always unplug the unit from the
wall outlet.
2. To clean the trays and cover, wash them in warm water
and soap. Do not use scouring pad or any abrasive
cleaners. The trays and cover, but not the tray liners,
can be safely washed in the top rack of the
dishwasher.
3. Wipe the base clean with a damp cloth. Do not
immerse in water.

7100 Instructions sgle pg 6/18/01 9:46 AM Page 8
REHYDRATING
Foods which have been dehydrated can be rehydrated in
water. It can be done in one of three ways: (1) Fruits and
vegetables may be soaked in cold water for 2-6 hours inthe refrigerator; (2) they may be soaked in hot water or
immersed in boiling water for 5-10 minutes until reaching
desired consistency; or (3) they may be rehydrated while
cooking. NO seasonings, salt or sugar should be added
during this process. Generally, 1 cup of water should be
used for each cup of dehydrated food. To stew dehydrated
fruits, use 2 cups of water and simmer until the fruit is tender. After rehydration, foods can be cooked normally. To
avoid bacteria, rehydrated foods should be eaten as soon
as possible and uneaten portions refrigerated.
DRYING FRUITS
Preparation
■Wash fruits well and remove any bruised or overripe
portions. Peel if desired. Large fruits may be halved.
If pieces of fruit vary in size, they may be sliced 1/4” to
3
/8” thick for more even drying. Smaller fruits such as
grapes and cherries may be dried whole. Remove pits
from fruits such as prunes, cherries, apricots, etc.
■Fruits that have been artificially waxed to prevent mois-
ture loss should always be peeled. Peeling is optional
with other fruits. Dried pear skins tend to be grainy
and peach peels are a little fuzzy.
■Most fruits can be placed directly on the drying trays as
they are prepared (such as pineapples, grapes, strawberries, prunes, etc). However, apples, apricots, pears
and peaches turn brown when the cut surfaces are
exposed to the air due to oxidation and the continuous
reaction of enzymes. These fruits may be pretreated to
slow this browning and prevent loss of Vitamins A and
C, but your attention is called to the cautions set forth
below which are for your protection. If you are drying
these fruits, and you intend to pretreat them, cut pieces
can be prevented from browning while they are being
prepared by keeping them in a holding solution until
you have sufficient fruit to pretreat or by vacuum sealing
them.

Food Dehydrator
Pretreatment (optional)
Below are listed several optional methods of pretreatment.
You need not pretreat food in order to dry it. However, pretreatment often makes food look better, increases the shelf
life and can even enhance the nutritional value of some
foods. Experiment with both treated and untreated food in
your storage to see which will best suit your needs.
Remember, proper storage is critical to the quality of the
stored product whether treated or untreated.
■Natural Predips: Use pineapple or lemon juice to
reduce browning. Slice fruit directly into juice. Remove
promptly (about 2 minutes) and place on trays. Fruits
may also be placed in honey, spices, lime or orange
juice, jello powders or sprinkled with coconut to give
them a snappy dried flavor. Use your imagination and
make your own flavor dip.
■Sodium Bisulfite: Ask for food safe, (USP) grade only.
Dissolve 1tsp. of sodium bisulfite in 1qt. water. Prepare
small amounts of fruit and dip for 2 minutes in the solution. This helps prevent loss of Vitamin C and maintains
a bright color.
■Popping Backs: When drying fruit halves, especially
apricots, it has been suggested that popping the back
(“inside out”) will speed the drying time. This is true,
but it also results in the loss of the nutritional juices to
the bottom of the dehydrator. Instead, cut each half in
half again to give the end product more nutritional
value, brighter color, & faster reconstitution capabilities.
■Ascorbic Acid (powdered vitamin C): use 3 tablespoons
per quart of water. Slice the fruit into the solution for 2
minutes, drain and place on trays to dry.
■Checking: Some fruits have a natural protective wax
coating, such as figs, prunes, grapes, blueberries, cranberries, etc. To speed drying, it is necessary to pretreat
these fruits by dipping them into boiling water for 1 to 2
minutes, depending on the size and toughness of the
skin. This makes the skin more porous by removing the
natural wax coating and thereby speeds up the drying
time. Fast drying helps reduce natural loss. This
process is called checking because small lines appear
on the fruit skin and allow the moisture to escape. The
lines are too fine to be visible.

Fruit leathers, also called fruit taffies or fruit rolls, are easy
to make in your Deni Food Dehydrator. Fruit leather is a
perfect “take along” snack, high in energy and nutrition.
Because fruit leather is made from a fresh fruit puree, a
solid surface must be used for drying. If poured directly on
the trays it would seep through the openings. The solid
lining fits into the regular trays. Alternately you may cover
the regular trays with a food grade heavy plastic cut to fit
the circular trays.
Fruit leathers are best made from fully ripe fruits. Wash
fruits carefully; cut away any bruised or spoiled portions of
the fruit; remove the pits or stones and blend in a blender.
Peeling is not necessary unless the peels will detract from the
finished product, as in pears or peaches. Fruit leather from
very seedy berries is best when at least some of the seeds
are removed with a sieve. If the fruit will not begin blending
by itself, add a little fruit juice to begin the blending process.
Add a small amount of honey or corn syrup if sweetening is
needed. Remember that the sweetness will concentrate as
the leather dries. Honey or corn syrup does not crystallize
in the finished leather during storage. Sugar sweetened
leather gets brittle during storage.
Pour puree 1/4” thick in a circle on the fruit roll trays. When
using food grade plastic instead of the fruit roll tray, leave
10
Lemon juice, orange juice, fresh pineapple or slightly
cooked apple mix well with most fruits and add additional
flavor. Some fruits are best when used in combination with
other fruits, so experiment with different combinations.
It is fun to vary the flavor of fruit leather by adding spices or
flavorings (such as cinnamon, nutmeg, almond extract or
vanilla).
For a change in texture, try sprinkling the wet fruit leather
puree with grated fresh or flaked coconut, nuts, finely
chopped dried fruit, sesame or sunflower seeds. Remember
to store garnished fruit leather in the refrigerator or freezer
as it has a shorter shelf life than plain fruit leather when
stored at room temperature.
Fruit leather is dry when it is no longer sticky to touch yet
still pliable. Remove from the dehydrator while still warm,
cut into quarters and roll. Wrap tightly in plastic wrap
designed for the microwave or freezer (it is airtight and
moisture proof), then store in an airtight container. We
recommend the Deni Freshlock® vacuum canisters.
Fruit leather will usually maintain a good quality up to a
year when properly packaged and stored at room
temperature. To keep them fresher, or for longer storage,
vacuum seal in plastic bags and refrigerate or freeze.

DRYING VEGETABLES
Vegetables dried at home require a little more effort in
processing and storage than do fruits because they are low
in acid and have little sugar. Some vegetables such as
broccoli or asparagus have a poor quality when
rehydrated, and are better frozen than dried. Others, such
as potatoes, are available at reasonable prices all year
round and may not be worth your time to dry them unless
they are used for lightweight camping. Be selective in the
vegetables you choose to dry, following the recommended
guidelines. Vegetables that are not listed do not dry
satisfactorily.
Preparation
Select only the highest quality, fresh, crisp and tender
vegetables for drying. Wash vegetables carefully just before
processing to remove dirt and bacteria. Most vegetables
should be peeled, trimmed, cut, or shredded prior to drying.
PreTreatment
Steam blanching vegetables prior to drying destroys the
enzymes that produce off-flavors during storage, resulting in
poor texture and poor rehydration. Steam blanching is
preferred over water blanching because there is less flavor
and vitamin loss. Microwave blanching is also excellent
and usually keeps a brighter color in the vegetables.
Steam Blanching
Layer prepared vegetables in the top portion of a steamer,
no more than 2 to 2-1/2 inches deep. Steam until the
vegetables are heated all the way through, but are not
cooked enough to eat (usually 2 to 3 minutes). Small pieces
may need occasional stirring to steam blanch evenly.
Transfer steamed vegetables directly to drying trays working
as quickly as possible.
Microwave blanching
Microwave ovens are convenient for blanching fresh
vegetables. Prepare vegetables as for steam blanching.
Place vegetables with small amount of water (refer to your
microwave oven cooking chart) in a covered casserole dish.
Cook for only 1/4 to 1/3 the time specified in the chart
stirring well after half of the blanching time. Microwave
blanched vegetables will be more brightly colored than
those that are steam blanched. Transfer blanched vegetables directly to drying trays working as quickly as possible.
Drying
Dry vegetables until they are tough or brittle and package
according to directions under STORAGE.

DRYING MEATS AND FISH
Your Deni Food Dehydrator makes two types of dried meats
or fish: JERKY- dried, marinated, raw meat or fish that is
consumed without added water-and DRIED COOKED MEAT
OR FISH that is cooked, cut into small pieces and dried.
Since most bacteria in raw meat and fish is destroyed during cooking, salting is unnecessary. Adding water reconstitutes dried cooked meat or fish.
CLEAN AND PREPARE MEAT WITH SPECIAL CARE
Meat products are more susceptible to harmful bacteria than
other foods. When handling any of these meats, dried or
fresh, take these precautions:
1. Wash hands thoroughly with a mild solution of detergent
bleach, and water.
2. Wash all utensils, bowls, dishes, counters and chopping
boards with this same solution.
3. Thoroughly wash food trays after drying meat, fish or
poultry.
4. After opening a sealed container of dried meat, fish or
poultry use it all as soon as possible.
MEAT JERKY
Fresh or frozen lean meat makes the best jerky. The lower the fat
content of the meat, the better jerky it will make. Lamb and cured
pork (ham) expire sooner because of their high fat content. Pork
must be well-cooked before using it for jerky - use only precooked and processed ham.
Four pounds of lean, boneless meat makes about 1 pound of
jerky. Follow these steps:
1. Slice the meat evenly into 3/16” to 1/4” thick slices. (Meat is
easier to slice if partially frozen). Cut across the meat's grain
for more tender jerky and remove all excess marbled fat that
could spoil during storage.
2. Place the meat slices in a flat glass container and generously
sprinkle each layer with a seasoning mixture that contains at
least one teaspoon salt per pound of meat. Place the next
layers on top; season each layer. Tightly seal the container.
Soak in salt mixture in refrigerator for 6 to 12 hours. Stir
occasionally.
3. Place paper towel on drying trays to soak up excess oils.
Place meat strips on the paper towel without overlapping
strips. Dry until meat cracks when bent and no moisture
remains. Store in an air-tight container, Deni Freshlock®
vacuum canisters or Freshlock vacuum sealer plastic bags
and keep cool. Flavor will last longer if refrigerated. Eat
within 3 months.

Food Dehydrator
A marinade is an alternative to salt mixture in jerky.
MARINADE RECIPE FOR JERKY OR FISH
For 4 pounds of meat or fish, use;
1
/2 cup liquid smoke1 cup soy sauce
1 teaspoon salt
1
/2 teaspoon pepper
2
/3 cup water
Mix and let stand while preparing meat or fish. Place
meat or fish in a bowl and cover with marinade, tossing to
coat all pieces equally. Let stand 6 to 12 hours. Drain in
sieve and dry.
FISH JERKY
Low-fat fish make good jerky since they are less oily and
have a longer shelf life. Four pounds of fish makes about 1
pound of fish jerky.
1. Keep fish cold to reduce risk of spoilage. Properly
clean them, remove bones, and cut into strips 1/4” to
3
/8” thick. Soak in a refrigerated brine of 1/2 cup salt
to 1 quart water for 30 minutes.
2. Remove from brine and pat dry with paper towel.
Layer fish in a glass container and generously sprinkle
each layer with a seasoning mixture. Use about
1 tbsp. salt mixture for two pounds of fish. Tightly
cover and refrigerate 4 to 8 hours.
14
3. Place paper towel on drying trays to soak up excess
oils. Place fish strips on paper towel without overlapping.
Dry until they are hard, dry, and tough, but do not crumble
and no moisture remains. Jerky made from fish with a high
oil content will have an oily texture that is not moisture.
Store in airtight containers, Deni Freshlock® canisters or
Freshlock vacuum sealed bags. The flavor remains longer
when refrigerated. Eat within 3 months.
DRIED COOKED MEAT OR FISH
Any type of fresh, lean meat, poultry or fish may be cooked
and dried. Dried cooked meat or fish will last about 2 weeks at
room temperature, therefore, it is better to dry small quantities.
Meat can also be ground for sandwich filling. Store dried,
cooked meat and fish in the freezer to maintain freshness until
you are ready to eat it.
1. Cook meat thoroughly, remove from cooking broth, drain
fat, and refrigerate. Cut into 1/2” cubes after removing fat.
Place paper towel on drying trays, then place meat on the
paper towel. Dry until meat appears hard or crisp and all
moisture is gone.
2. Store dried, cooked meat or fish in an airtight container,
Deni Freshlock® canisters or Freshlock vacuum sealed bags
and consume within 2 weeks. For longer storage, keep in
the freezer up to 2 months.
3. To reconstitute, soak in hot water or broth from 30 minutes
to one hour or until plump. Add to recipe and simmer 15 to
20 minutes.
