So you’ve stumbled across the Excalibur 3900 and want more details, eh? You’ve come to the right place. Is the Excalibur 3900 the best? You’ll have to decide what’s best for you; I’m just here to give you the facts.

In terms of power, the 3900 comes in at the low end of the scale for food dehydrators. The motor is 600 watt. For the most part, the food dryers I’ll review are between 500 and 800 watt, so you’ll see it’s a little lower than mid range. What does that matter to you? The higher the wattage the less cooking time. Here’s a comparison between a 600 and 800 watt microwave. What would take 10 minutes to cook in a 600 watt microwave will only take 7.5 in an 800 watt. We’re not comparing apples to apples, but that gives you an idea at least. If time is of the essence this might be a big factor for you. If you’re thinking about your hydro bill, it’s likely a wash. It’s either more power and less time, or less power and more time, so it could all come out about the same.

Excalibur 3900 Food Dehydrator Pros and Cons

Pros: Large size – Rectangular shape – Fan on side (Horizontal Drying System) – Fan Issues seem to have been solved.

Cons: Pricy – Noisy – No timer – Only 600 watts


The Excalibur 3900 measures 17 x 19 x 12 and has 9 trays, which is about 15 square feet of drying surface, making this a great unit for larger quantities. And since large quantities very quickly become small quantities after drying them out, that’s a very good feature! If you have the space, I would suggest a large model like this one.

Another plus for some, is that this is an American Made product, so if you do your best to buy American, keep that in mind.

If you plan to use this as a beef jerky dehydrator, actually if you plan to use it for any kind of meat or fish that could contaminate the trays with bacteria, you really should be using tray liners as well. They are termed optional, but in my opinion they aren’t. If you feel the same, here is a tip. Do not buy the original Excalibur liners. The price is ludicrous. About $10 per sheet! Amazon has a 9 pack of liner/sheets for about $16 and you can usually find them listed right under the dehydrator.

As mentioned on the main page of our dehydrator reviews section, having the fan anywhere other than the bottom of the unit is a good thing. The Excalibur 3900 has the fan placed at the rear of the unit. A few benefits of that are nothing dropping or dripping down onto the fan, and even more important, the horizontal flow means an even distribution of heat on the trays. You won’t have to rotate them like you would have to on some other models. This feature alone makes the 3900 one of the best food dehydrator selections.

What are the drawbacks of this model? No timer. So make sure when you start a project you will be home and not in bed when the time is up.

It’s noisy! But really, aren’t a lot of small kitchen appliances?

It seems that Excalibur had a huge issue with the fans breaking down a few years back. You’ll find a ton of complaints about that online, but the good news is that it seems to have been address in new models, so there is less chance of you ending up with a lemon.
