Distributing Heat

Many dehydrators have the heating element at the bottom, which means when the heat rises the temperature at the bottom tray is the warmest, and by the time it gets up to the top its cooler so you have to rotate your plates. Excalibur says that their products are better at distributing heat and at drying food because they have a rear fan and it flows air across all the trays.

Meaning with the Excalibur, you will never have to bother to rotate your treys.

Hiperwave Technology

One of the best features of the Excalibur dehydrators is the feature called Hyperwave technology.

How does it work? Well, the device changes the temperature itself. For example, if you set your temperature to 115 F the heat will wary between maybe 105 on up to a 125 within a 10-degree range mainly in effect to help dehydrate your meal faster. If you don’t do this what happens is called case hardening where the outside of the item will be dried while the inside will remain moist. Hyperwave helps you decrees your dehydration time.

Trays and Sheets

One of the most important features is that the trays could be separated, which is a must for drying higher foods and having easily removable plates is a big plus.

You can dry a lot of food on big 15 by 15 inches trays. Nine stackable plates can be removed easily meaning some of them can be eliminated to stuff larger items, and they are easy to clean and dishwasher friendly.

There are many models to choose from, now more than ever, but you will notice they are pretty much the same. The Excalibur 3900b has nine treys, and you get nine mash sheets. You can dehydrate pretty much anything from sliced vegetables you can even dehydrate a sliced tomato and it actually won’t go through you can put them right up on the mesh sheet sliced, and they will dry.

If you want to do things like fruit roll-ups or some raw food recipes where things are moist and liquidly you will want to use a Teflon sheet. Note that they they don’t come in the package and must be purchased separately. If you plan on using mostly moistly food with it, you should use Teflon layers so that there is no dripping from the food itself. No need for some more expensive models with stainless steel since you are going to cover them up anyway thus you will save a lot of money.

However, if you want a more premium feel and plan on drying something more sensitive to bacteria, then you should consider geting stainless steel trays. You can even use it for raising bread or incubating yogurt so it is a pretty multifunctional tool.

Difference Between this and Previous Model

The main difference between the 3000 series and 2000 series of Excalibur dehydrators is the same thing as if you are buying their previous models only upgraded in their features.

So both dehydrators will dry your food, but 3900b is the upgraded model that has little better components. The fundamental changes that are updated:

  • The motor that will last more than 15 years of continuous use over whole day usage. Higher quality components versus the 2900 economy series
  • It has upgraded thermostat that Excalibur claims it will last five times as long
  • Enhanced heating components
  • Improved material of trays made of Noryl and polypropylene
  • Upgraded electrical installations
  • Maybe the most important thing is the extended warranty that now lasts ten years

Additional Features

  • In the package with the dehydrator comes a 50 recipe manual so it doesn’t matter if you want to cook fruits like bananas, apples, beef jerky or vegetables you’ll know how to do it using plenty of recipes.
  • The doors are made just to hang, and they don’t close the device entirely so that the moisture can flow through. If you fully load on the device, some of the moisture can accumulate on the edge of the door and from the bottom of the machine so you may want to watch out for that part.
  • Note that this unit can be loud with the fan like this and on a surface made of metal or a kitchen counter it can vibrate a little bit. And be extra noisy so putting a placemat under it is recommendable to keep it quieter, the vibration is the most troublesome and merely the fan turning is not that loud.


A lot of people will find this model a bit basic, and it is not the prettiest thing in the kitchen, but if you are looking something to dehydrate lots of food, prepare lots of meals, keep it running all the time this is a device for you. Some citizens purchase the Excalibur 3900b who have small raw food businesses.
