  • Excalibur 3948CDB 9-Tray Digital Food Dehydrator With 48-Hour Timer

    The Excalibur® Model 3948CDB, 48-hour Digital Controller Dehydrator, comes with 9 Trays and a clear door so you can view progress without interrupting the drying process.  The 48 Hour, 2 Time / 2 Temperature Digital Controller lets you set the dehydrator and forget it.  To speed up the drying process, set the dehydrator at a higher temperature for a specified period of time; and then set the dehydrator at a lower temperature for a specified period of time.  The unit will automatically adjust the 1st setting and turns off when the 2nd setting is complete. The Model 3948CDB comes complete with 15 square feet of drying space, 7” fan, adjustable thermostat 95 ̊F – 165 ̊F, Hyperwave™ Patented Technology and Parallex Horizontal Air Flow.

    The Excalibur Dehydrator removes water from food by a continuous circulation of thermostatically-controlled warm air. A variety of foods, from bright golden kernels of farm-fresh corn to rings of island-sweetened pineapple can be dehydrated. Slices of beef, chicken, fish or even venison can be easily dried into homemade jerky. A fruit puree dries into a vividly colored, taffy-like snack or fruit roll.  Make soup mixes, herb and spice mixes, yogurt, arts & crafts ... even all-natural pet treats.  Operating cost for your Excalibur® Dehydrator is approximately 3 - 6 cents per hour. Using your dehydrator compared to traditional canning or freezing methods will prove to be well worth your initial low-cost investment.

In constant use

Since receiving my Excalibur I have had something going almost non-stop. Here are my bullet points so far: -- This dehydrator holds a phenomenal amount a product. I was amazed the first time I used it! -- The drying is very consistent. I have heard that you need to rotate items when drying. While it might not hurt to rotate, if you forget don't worry. -- The book that came with the unit is very clear and takes some of the worries out of the process if you have never done this before (which I hadn't) -- I love the clear door. Some things to consider (by buyers and/or manufacturer): -- Cost. It is the highest priced unit on the market and I was actually surprised that the unit is almost entirely plastic (and super light for the size). Just seems kind of cheap (when it is not). -- The top shelf has significantly less space that every other shelf, so if you are rotating you can't put stuff on the top shelf. Increasing the overall height by 1/2 inch would solve this. -- If you are buying I would suggest that you get the tray liners. On our first products, we placed items directly on the screens and they were a pain to clean. We are now using parchment paper and it is a pain to keep cutting to fit.

Meets all my demands

I wanted a quiet dehydrator that would be a regularly used appliance in my kitchen. It needed to fit a large quantity to make dehydrated food a part of our regular diet. My perfect dehydrator needed to have specific temperature and time controls as well.

This dehydrator meets every requirement and then some. I love that you can take the door off to check on the food without stopping it or re-setting the timer. The nine trays fit a huge amount of food! I can fit four thinly sliced tomatoes on each tray to make tomato chips. Then fill eight more trays!

It is very quiet -- almost the exact same volume and pitch as my microwave. It's not a distraction nor a nuisance, and the entire family is now used to it running in the background as part of our normal routine. It sits right in the middle of the kitchen and is running daily with a new batch of healthy snacks.

I have used other dehydrators in the past, but they never really dried the food well. This dehydrator is perfect for making chips out of vegetables that have the real crunch to them. There is no case hardening and the products come out uniformly dried without rotating the trays.

Well done Excalibur!

Liked it so much

I got one of these and got another one. It is just what I wanted. I love the controls.

Fantastic dehydrator!

I have been on a dehydrating binge ever since receiving my Excalibur! I absolutely LOVE it!

My 2nd Excalibur!

I just got this one today and have already used it to dry peppers. It works great and I do really like the digital control and the clear door. I've been using Excalibur's for about 6 years now and my first one, which is a 3629TB, has never missed a beat. I bought a clear door for it recently, so now I feel like I have 2 new dehydrators.
