Excalibur 3900B 9 Tray Excalibur Black
The 3900B Deluxe Dehydrator by Excalibur comes with 9 trays and a total of 15 square feet of drying space. The adjustable thermostat temperature control ranges from 105 to 165 degrees Fahrenheit, making it safe to dehydrate meat for jerky. The fan, heating element and thermostat are in the back of the unit, so cool air is drawn in, heated and then distributed evenly over each tray. This patented Parallex Horizontal Airflow is exclusive to Excalibur and helps the food dehydrate faster, retain more nutrients, and look and taste better – all without manual tray rotation. Since 1973, Excalibur has been made in Sacramento, California. Over the years, Excalibur has taken the lead in advancements related to the mechanics of dehydration including air flow, heating dynamics, and materials.
Any dehydrator will dry food. An Excalibur dries safer, better, and faster, thanks to Excalibur's patented Hyperwave Fluctuation technology. Ordinary dehydrators produce constant, unchanging heat, which can cause"case hardening." Ordinary dehydrators create a dry surface with moisture trapped inside – the perfect environment for yeast, mold and bacteria growth. With the Excalibur Hyperwave Fluctuation technology, the temperature fluctuates up and down to prevent this from happening. When the air temperature fluctuates up, the food's surface moisture evaporates; then, when the air temperature fluctuates down, the the inner moisture moves to the drier surface. This keeps the food temperature low enough to keep the enzymes active, but the air temperature gets high enough to dry food and overcome yeast, mold, and spoilage.
- 9 trays and 15 square feet of drying space.
- No moving food or trays during dehydration.
- Adjustable Thermostat 105 to 165 degrees Fahrenheit. Safe to dry meat for jerky.
- Accurate temperature controls to dry fruits, vegetables, meats, flowers, herbs, pet treats, arts & crafts.
- Dehydrate faster with square trays that hold more food.
- Remove trays as needed to increase the height needed to dehydrate bulky items or raise dough.
- 7-inch fan, 600 watts. Unit Dimensions: 12-1/2 H x 17 W x 19 D (inches)

I have also dehydrated bananas, apples, and pineapples with great success. This is a great machine!
The bottom of the unit does not have any kind of lip or tray to prevent drippings from oozing under the mesh screen at the back of the drying space, which prevents things from getting into the fan. In my case, it was beef fat.
There is no way to remove the screen easily, and you can't even get the back off the unit. Without pulling the whole thing apart and risking damaging it, there is no way to clean up spills & residue from the back of the unit behind the screen.
If I had been warned that I should line the bottom, or if there was a removable tray, I would not be complaining. Do the creators of these products think this kind of thing through before they manufacture? Very disappointed.
The round tower-type dehydrators are inexpensive for a good reason: they aren't worth it.
-The trays are flimsy and crack too easily.
-The holes on these trays are too big to use with herbs or diced foods, so you must use the mesh inserts.
-You only have about 1/2" of space between trays, so you cannot dry bulky items--like flowers or granola.
-When it comes to fruit leather, the only thing more inefficient than the round shape is the hole in the middle. Yes, I know they come with fruit leather trays, but have you ever tried to store fruit leather pealed off of the tray and rolled up? A shredded mess to begin with and a sticky mess once they've stored for a while.
-With the motor on the bottom any food or juices that fall through the cracks shortens the life of the machine.
-The drying process in these tower-types is not uniform--the bottom trays dry quicker than the top trays, the center dries quicker than the edges.
-Some models have only recently started adding temp controls. Still, it does little good because there is more heat on the bottom than the top.
-The motor is loud--I had one model I had to run on the porch because it was so loud.
The two round models I bought died within a year and a half of use.
The next best dehydrator on the market is the L'Eqip. It is much quieter, comes with a healthy 10yr warranty and has temperature controls. But it is a hybrid with many of the faults of the round models and few of the benefits of the square-shaped Excalibur. It still has a hole in the middle. It still dries unevenly. It has deeper trays but you still can't dry flowers. It still has a motor on the bottom. I have a friend who dried berries in her L'Equip. They leaked on the motor and it died the first summer of use. Now granted, the folks at L'Equip stood by their machine and replaced it for her with no hassle, but how many times do you want your summer-time dehydrating held up while you wait for your replacement to come?
The Excalibur is perfect for anyone who is serious about dehydrating. Here are the features that I like:
-Heat source and fan are in the back, forcing air to distribute evenly throughout the chamber. Other than the way you place the food, there is no reason for uneven drying spots.
-Love the timer. I can set it and leave. It'll turn off automatically whether or not I'm there. That means 'round the clock drying during the height of your summer harvest. Put the food in when you go to bed, wake up to dried food and put another batch in.
-Temp control lets you choose low heats for herbs and flowers, higher temps for fruits and jerky.
-Love the square trays. For fruit leather I line the trays with plastic wrap and spread the fruit puree out. When it's dry I cut the leather into 2" wide strips, roll them up and secure with the tail end of the plastic wrap. The plastic peels off easily when it's time to eat.
-BIG trays--you can pack a LOT of food into this. This is especially important at the height of the summer harvest when there's a non-stop stream of food that needs drying. (This is also the one single thing that is in my negative column--the trays don't fit flat in my kitchen sink, making them a little hard to wash. I solve this by washing them in my outdoor garden sink--old fashioned tubs on a stand. Since I like the big trays, I really shouldn't complain.)
-Mesh liner on all trays. I can dry herbs, diced onions and finely chopped fruits without having it fall to trays below. No food cross-contamination means I can dehydrate more than one thing at a time.
-Removable trays. If I have bulky items--flowers, herbs, granola, etc--I can just remove every other tray and have another 1/2" or more room.
-Makes a great proofing box for sourdough. Also good for culturing yogurt, esp if you like to make it in larger containers. For both sourdough and yogurt, make sure it is covered so that the moving air doesn't dry it out.
-10 yr warranty. I've had mine for almost 15 yrs and it's still going strong. Every year the money I save on herbs alone pays for what it originally cost me. That means this machine has paid for itself 15 times over.
If you're at all serious about dehydrating, don't waste your money like I did--get the best from the get go. That's the Excalibur.
