The highly-regarded Excalibur 3926TB has copious tray space and a roomy cabinet, making it one of the largest machines we tested. This square footage is a luxury for cooks requiring high-volume food preservation. The mesh-lined trays can be removed and soaked or scrubbed in the sink or dishwasher, which significantly aids in the cleanup of sticky food bits. More importantly, this model produced consistently positive results for texture, evenness, and flavor across our test foods. This is largely due to the 3926TB's relatively accurate temperatures, particularly at the high and low ends of the temperature range.
While the Excalibur 3926TB's tray space is a boon to the high-volume cook, the external dimensions can burden those with limited storage space. Also, the interior plastic's rough texture is hard to wipe down, complicating cleanup. Lastly, the markings on the knobs are imprecise, which may explain some of the inaccuracies that we observed in the middle-temperature ranges. Despite these shortcomings, the 3926TB is a noble machine for both casual and intensive dehydrating. If you don't want to shell out this much money, take a look at the Presto 06301 Dehydro, which offers totally decent dehydrating performance for a fraction of the cost.

For those who want their food dehydrator completely out of sight while not in use, Brod & Taylor has devised a spectacular design for their Saraha Folding model. While in storage mode, it takes up one-third of the space of its operating size. It easily converts between storage and operating modes with a few quick and easy adjustments. Considering all of the Sahara's functions and settings, our team found this appliance to be simple to operate. An integrated air filter helps keep contaminants off your food, and this model is especially quiet while running.
Although we love the innovative collapsible construction, converting the Brod & Taylor Sahara Folding adds extra steps that aren't necessary for other models. If you use your dehydrator often and don't mind it permanently living on the counter, there's no reason to go with a folding version. Also, there's no getting around the fact that the Sahara will put a dent in your checking account. If you're shopping on a budget, this is not the one. Despite the price, we highly recommend this model for those who want a full-sized food dehydrator with a much smaller storage size. If you have the storage space, the Tribest Sedona SDE-S6780-B is another premium model, but it's quite costly.

BPA (Bisphenol A)
In recent years, BPA has become an increasing concern for many consumers. While the FDA maintains that BPA is safe in food contact materials, many manufacturers have responded to the apprehension of their customers by avoiding materials containing the chemical. All of the dehydrators in this review have BPA-free trays. The Cosori, Presto, and Hamilton Beach models are completely constructed of BPA-free materials.

Analysis and Test Results
At the most basic level, a dehydrator is an enclosed space containing racks or trays, a heating element, and a fan. Within this basic design are two categories of dehydrators: shelf dehydrators and stackable dehydrators. Shelf dehydrators look like a box with racks that slide in and out. A stackable dehydrator features trays that fit one on top of the other with a lid enclosing the unit. The Excalibur is an example of the shelf style, while the Nesco models are an example of the stacked design.

There are variations among these products in the user interface, cleaning ease, capacity, and temperature accuracy. Your goals, including frequency and what you intend to dehydrate, will determine the importance of these elements. We will look at all these considerations in detail below. While you read the following, consider how much space you want to dedicate to storing your dehydrator. In our opinion, many models will not look aesthetically pleasing on a countertop, and even those with a sleeker look will take up a lot of counter space.
Value
With food dehydrators, we have found that it is often the case to find a range of performance for a range of prices. If you're willing to shell out for some specific features, the Excalibur 3926TB is best for those looking to run large batches, and the Brod & Taylor Sahara Folding collapses to one-third of its operational size for storing. If you're shopping for a food dehydrator on a budget, the Presto 06301 Dehydro showed commendable performance at a fraction of the price of the top-scoring models. The Nesco models also perform decently for an affordable price.
Dehydrating
For most, it's not enough to desiccate food so that it won't spoil.
Good dehydration is a delicate process that leaves just enough moisture in the food to make it easy and enjoyable to eat while preserving it for the long term. It should be noted that there are some important food safety considerations provided by the USDA that need to be understood before dehydrating meat. With these good practices in mind, let's dig into the food.
Dehydration doesn't always mean desiccation. Toms require a bit of moisture to make them palatable. Accurate time and temperature are critical to this outcome.

To evaluate the dehydration process's final product, we made fruit leather, tomatoes, herbs, and beef jerky using the times and temperatures recommended by each manufacturer. These foods require different methods of preparation, temperature settings, and timing. We had a panel of tasters evaluate each dehydrator's final product for texture, evenness, and flavor. We also recorded each recipe's completion time and compared that to the time listed in the manual. Often, some tweaking of the period of dehydration was required, resulting in a disparity between the manual's recommendation and the actual time required.
The Excalibur 3926TB, the Presto 06301 Dehydro, and the Nutrichef PKFD12 are standouts in the category. They produced evenly dehydrated, tasty morsels across all food types using the manufacturer's recommended time and temperature settings.

Temperature Accuracy
A dehydrator's temperature accuracy is not just the ability to precisely set a digital interface to a specific number. Temperature accuracy means that the number on the interface accurately represents the machine's internal temperature.
It seems obvious, yet the results varied greatly from one model to the next upon testing. We selected temperature settings of 100, 115, 130, and 160 degrees Fahrenheit (all common dehydrating temperatures) on each machine and placed a thermometer inside. Except for the Chefman 6 Tray Digital, which ran cool, all the other models displaying deviations consistently ran hot.
Temperature accuracy and consistency are critical for high-quality outcomes.

The Presto and the Cosori demonstrated the greatest accuracy within the class. The Cosori never varied more than three degrees from the set temperature. Scoring just behind these models was the NESCO Snackmaster Pro. And even though it has several areas that you might think would lose some heat, as well as glass doors, the Brod & Taylor Sahara Folding also showed a large degree of accuracy.
We were pleasantly surprised to find that the Sahara temperatures were relatively accurate even though the entire device can be collapsed into a storage mode.

Ease of Cleaning
Often culinary activities require more prep and cleanup than actual cooking. While prep can be enjoyable, cleaning is rarely described as such.
Dehydrators have a lot of nooks and crannies, trays, and liners. Moreover, the slow dehydration process provides ample time for the food to drip, thicken, and harden into these spaces. If your dehydrator takes too much time and effort to clean, you might find it collecting dust in the pantry. To help inform your decision, we thoroughly analyzed the cleanup process for each machine.

We ran a variety of food through these machines during our testing process, giving us plenty of opportunities to clean sticky substances from them. We found that models like the Nutrichef and Hamilton Beach 32100A are easiest to clean since the trays comprise the body of the dehydrator, and you can unstack them to disassemble the appliance. As a result, there are no tight corners that are hard to wipe out.

Ease of Use
For our purposes, ease of use specifically refers to the user interface, cooking capacity in the form of square footage, and tray design. A few dehydrators stood out with simple and intuitive temperature and timer controls.
Our favorite models for this metric are the Brod & Taylor Sahara Folding and the Tribest Sedona SDE-S6780-B. The Sahara features a soft rubbery wheel for adjusting time and temperature and buttons for the rest of the controls.

Some models, like the Nutrichef, are quite simple to use — in this case, all you have to do is plug it in and flip a switch. However, this streamlined start-up process comes at the cost of a timer and thermostat; the user must time the process manually. On the other hand, models like the Excalibur 3926TB have dial adjustments for temperature and time. While knobs get the job done, they lack the degree of accuracy provided when you can fine-tune a digital interface to precise specifications.

If you're looking for a food dehydrator with ample cooking area, the Excalibur 3926TB and Brod & Taylor Sahara Folding offer 15 square feet of total tray space. The Tribest Sedona SDE-S6780-B is not far behind at 9.9 square feet.
The Tribest Sedona offers nearly ten square feet of total cooking area.

While temperature and timing are crucial for achieving the desired edible outcomes when purchasing a dehydrator, a good tray design can determine how easily we reap those rewards. We discovered that the effort put into preparing and drying food is all for nothing if the food sticks to or falls through the tray. Trays with removable mesh screens are best for dealing with sticky or adhered food because they can flex and roll, breaking the bond between the tray and food.
Conclusion
Preserving food with dehydration is cost-effective, nutritious, and rewarding. If you are looking for a machine to achieve these ends, the above review lists several options to meet budget and space constraints. More than that, we isolate the models that are easier to use and clean. We had a great time testing these machines — including scarfing down all the snacks we made. We hope that our work helps you find your way through the dehydrator selection process and on to reaping some tasty rewards. Bon appetite!
