Review of the Excalibur 3948CDB 9-Tray Electric Food Dehydrator

Do you love sinking your teeth into savory beef jerky or tangy fruit leather? With the Excalibur 3948CDB food dehydrator, you will see the amazing benefits of preparing delicious, portable snacks for your family at a fraction of the cost of pre-made, store-bought options. 

What is food dehydration? Food dehydration is one of the oldest known methods of food preservation, used by our pre-historic ancestors! It is still used globally as an ideal way of naturally preserving food. By evaporating the moisture content of meats, fruits, vegetables, and herbs, they become shelf-stable and more compact for easy storage or for grab-and-go snacks.

The Excalibur 3948CDB has an impressive list of features, including ease of use, portability, and a patented temperature control technology that ensures safe food preservation at home.


The Excalibur 3948CDB 9-tray food dehydrator has 15 square feet of food space. This means you can dehydrate as little as one small berry or several pounds at once.

The adjustable thermostat is super important. The lower temperature dehydrates fresh produce and delicate herbs or flowers without destroying healthful active enzymes. The higher temperature is necessary to safely dehydrate meat for jerkies or treats for your furry friends.

Because of the patented Hyperwave™ technology and Horizontal Parallex™ drying, Excalibur 3948CDB has a continuous heated air flow that effectively dehydrates your favorite foods without heating up your kitchen.

The unit is light weight and portable enough to use or store in any room of your house.

Easy to Use

The 3948CDB model boasts an easy to set and easy to read digital thermometer and 48-hour timer. The two time, two temperature option can be set at a higher initial temperature for a specific time. When that time ends, it automatically adjusts to the second set temperature and time, reducing the need for continuous monitoring.

The PBA-free plastic mesh trays have a tighter weave that keeps small food pieces from falling through the trays, but big enough to promote maximum air flow and consistent drying temperature. The trays are easy to clean with warm, soapy water, and the machine simply needs wiped down with a damp cloth.

The glass door enables easy viewing and monitoring during the drying process without the need to disrupt the internal temperature by opening the door.

Other Delicious Benefits

By making your own delicious snacks, you can assure the quality of every ingredient. From start to finish, you know exactly what is going into your food. This is important if, like me, you have family members with food allergies or are finicky eaters.

No more expensive beef jerky or sugar-loaded fruit leather. For school lunches, backpacking, running errands, you will have high-quality, healthy dehydrated food at your fingertips.

You can also save money by taking advantage of seasonal produce and great sales at the grocery store and dehydrate in bulk.


Although in very highly rated, The Excalibur 3948CDB 9-tray food dehydrator still has room for improvement.

Recommended Improvements

The food dehydrator Excalibur 3948CDB model is somewhat noisy, not noisy enough to hear it throughout the house, but noisy enough to know it is working. To buffer the sound, it can be used in a lower-traffic area of your home.

The manufacturer could also improve the packaging, providing better protection during shipping.


It is bulky and takes up a fair amount of counter space.

Necessary Accessories

The solid tray liners necessary to make fruit leather are not included with the dehydrator and must be purchased separately. Excalibur makes a silicone coated non-stick, ParaFlexx™ fruit leather sheet that fits most of their dehydrator models.
