The Best Quality Food Dehydrators – 2018 Buying Guide
If you’re like us, you probably have a few kitchen appliances on your counter or in your pantry that you rarely use. Maybe you got excited by the automatic potato peeler, or the dragon fruit slicer, or you were intrigued enough to purchase a "gelato extruder" - you never know, it could be real.
But those appliances sit unused in the back of all our cupboards, waiting for the once-in-a-year opportunity to be used.
A food dehydrator is not like that. It’s one of those appliances that will get as much use as your toaster, your microwave, or your coffee percolator. Your food dehydrator is your new best friend.
You know all those fruits and vegetables wasting away in the crisper of your fridge? There’s no way you’ll ever eat 2lbs of pumpkin before tomorrow, so what will you do? You hate to waste it, but you can’t manage to eat it.
You can always preserve it for when you’re ready. A food dehydrator serves as a simple way to make your fresh produce last longer without spoiling or turning rotten. You don’t have to wait for the next berry season to have fresh strawberries. You can have them year round if you’ve preserved them.
Our Top 5 Picks
What Can You Do With Your Food Dehydrator?
Are you worried that you won’t have enough use for the dehydrator? Don’t be. This will pay for itself again with the number of times you’ll pull it out.
This is just the first week. You’ll never run out of ideas when you own your food dehydrator. You’ll ask yourself, “Could I preserve this?” when out at the supermarket, and more often than not, the answer will come back ‘Yes’.
It can be daunting to try and select a food dehydrator if you’re unfamiliar with the appliance. When you first look for a unit, you’ll get bombarded with phrases like Stackable, Box-and Shelf, Closed System, Square Footage, Vertical/Horizontal design, and wattage/temperature.
These can get confusing when you’re still learning how you’ll use one. So let us guide you as you decide on your best food dehydrator.
With a product this popular, there’s enough science to back up the reasons for making the purchase. But before we get into the ‘How’ of the machine, let’s talk about the “Why.”
The main reason you want to dehydrate your food is to preserve the natural vitamins and minerals in the food without getting any spoilage. The main reason food spoils is the presence of moisture and most foods have moisture in it - anywhere from 2% to 96% moisture.
It’s not that the actual moisture in the food causes the food to go bad but the presence of moisture means that bacteria and fungus can grow in that environment. You can’t get rid of bacteria in your environment, but you can limit where it can grows.
You know how it was a big deal that we found water on Mars not too long ago? Because that’s the best sign that life can exist. No water? No life. Simple as that.
So, the same principle applies on a micro scale on your food. As long as you can find a way to stop bacteria from growing, you can extend the life of your food for 6 months, one year, even up to 5 years!
There are a few methods to preserving foods and extending its shelf life. They may vary considerably, but the main purpose is always the same; stop bacterial growth.
If you can find a way to keep bacteria from contacting and thriving on your food, you can preserve it.
One of the most common ways is to freeze your food. By putting your food into a sub-zero environment, nothing can grow on it. But this takes up space in your freezer and requires constant power. What happens if you want to take food with you, say on a hike? As soon as you remove food from the freezer, you start the timer as to when it will thaw and start to go rotten.
Another way is to can your fruits and vegetables. Canning involves submerging your fruits and vegetables in some sort of brine or liquid, trapping them in an oxygen-free environment. If you can’t remove the liquid, remove the oxygen that bacteria need to breathe. Think about pickles, peaches, jams, jellies, and even Korean kimchi. Preserved vegetables in vinegar brine can ferment and preserve the food for up to 3 years in a simple clay pot. Fermenting and preserving food this way takes space and effort to create an effective brine or canning liquid.
The best method, and certainly the easiest for any home owner, is to dehydrate the food. You can preserve the food as long as required in a cupboard or fridge. And when you’re ready to eat it, you can either open up the bag and start munching, add it to your cooking, or rehydrate the food to enjoy it as it once was.
The best method for preserving food is heated air that force-dries the moisture from the food, retaining the food’s structure and nutrients. The air is heated to anywhere between 90-150° Fahrenheit with a fan blowing the air across the surface of the food. The moisture is forced out by the heat and blowing air, while the food remains preserved and intact.
The benefit of using this food dehydration method is that you aren’t restricted by volume. You can dry as much, or as little, as you need. Dry out a couple of tomatoes, or stack up this season’s crop of fresh berries to dehydrate until you’re ready for them months down the track.
Of course, every food dehydrator is going to remove the moisture from the food. But you’ll find a whole host of other features on different models. Let’s take a look at what you should and shouldn’t look for on your dehydrator.
When buying food dehydrators, check to see if you stack the food on top of each other, or you have shelves. You’ll find advantages to both, and we’re not here to advise one way or the other. It entirely depends on how much you’ll use the product.
Vertical shelves make use of a sideways fan, usually mounted in the back of the unit. It blows air smoothly and evenly across all shelves. The real advantage to using a shelving system is that you can easily check different sections of the dehydrator. If you want, you can put different fruits and vegetables on each level, checking each shelf as they go. There’s no need to disassemble the entire unit just to check the tomatoes or the mushrooms.
The other option is the stackable vertical units. The fan blows from the bottom and reaches all the way through each stack. If you choose this option, you can stack as few or as many levels as you want. Many brands offer the ability to add additional shelves if you’d like to increase the capacity. But the top layers and bottom layers don’t get an even amount of air. You might need to experiment to find the right ratio for where best to put your foods for good results.
Try to find a model with an adjustable thermostat. You’ll most likely use the food dehydrator to dry out several different types of foods. But each food is best preserved at different temperatures. For example, if you’d like to dry out some of those herbs you have that you can’t use, you only need to set it at a low temperature around 95 degrees Fahrenheit. But if you want something more aggressively dried out, such as fish or fruits, you can set the temperature at 135 degrees Fahrenheit.
You can’t even dry out different foods, so find a model that has a thermostat to set your desired temperature. Furthermore, look for a dehydrator that has a high range of temperature so that you have more options. You'll get an even result, and a great product after the food is preserved.
✓ Even Airflow
Take some time to check out the fan size of different models. The size of fan determines how even the air will flow across the surfaces.
Depending on the vertical or horizontal model, it should have a good sized blade that can fan across all surfaces evenly. There’s nothing worse than having the food at the back complete while the food at the edge is still moist. Just like Pearl Jam tells us, you want even flow. Look for blades that are large, around 7” in diameter or more.
The capacity of your machine determines different variables. You’ll have the ability to dry more food, but it will use more wattage to power the unit.
Bigger units can handle large capacities, up to 31 square footage of drying space, but the wattage can be high as well. We’ve seen models with 1000+ watt requirements. If you’re going to use this size food dehydrator often, it could be worthwhile, especially if you’re preserving entire boxes of tomatoes, fresh cherries or peaches.
Otherwise, you might want to find a smaller unit. You won’t be able to fit as many foods into the machine, but you can easily store the unit away and power it without breaking the bank on your utility bill. You can still do fruit leathers and homemade kale chips, but a smaller capacity doesn’t have the space needed for a big trip to the farmer’s market.
Top 5 Food Dehydrators Compared
We’ve collated the best dehydrators on the market, and as you can see, there are plenty of options to choose from. Let us break down theses options so you can decide which food dehydrator will work for you.
Best for Beginners
The Nesco Snackmaster is a highly popular brand online. It’s garnered praise from thousands of satisfied customers, and we can see why.
The brand is well trusted in the food dehydration world. Nesco has quite a few different models available, but we chose the 75A for its wide market appeal. It works for casual beginners as well as heavy users.
The vertical stacking trays come with a set 5 levels, but you have the option of purchasing more if you need. The 600 Watt unit can comfortably handle up to 12 trays for an exceptional amount of drying. It will also keep out the UV rays for more effective preserving of your fruits and vegetables.
Adjust the temperature on the handy thermostat. It regulates the interior temperature while the top mounted fan blows the air downwards over the food. The science of the top fan doesn’t make sense to us. Hot air rises, and so it seems counter-intuitive to place the fan at the top.
It also comes at quite an affordable price. If you’re just getting into dehydration, it’s not an expensive way to begin. You’ll make your money back from the preserved food and reduced wastage in the first month if you use it enough.
What We Liked
- The adjustable thermostat
- The added trays for additional food dehydrating
- UV blocking sides
- Simple instructions and usages - good for beginners
- Great reviews online
What We Disliked
- Opaque sides don’t allow us to see the progress of dehydration
- Top mounted fan blows hot air downwards. Seems gimmicky when hot air naturally rises.
- If drying multiple varieties of foods, stacks must be re-arranged midway
If you’re looking for a unit that can handle all types of dehydrations, look no further. We like this Presto model for its versatility and ability to adapt to wherever you need it to do.
The bottom mounted fan and heating unit gives an even spread of the warm air to consistently dry out the top layer, the bottom, and anything in between. Although this comes with a standard 6 tray stacking system, you can easily add up to 12 if you’re looking for more capacity.
The clear top gives you a good look to check on the progress of your food. You can even use the added fruit roll trays to make your own fruit leather.
Don’t worry about adding any extra preservatives into your food, because this unit lets you quickly dry without needing anything other than warm, dry air. The mesh screens also allow for small and sticky foods to be easily dried out, just as well as anything else.
It has an astonishing amount of good reviews. Those who have made complaints note that the unit can be a little noisy. But if you’re drying out food during the day, the noise won’t bother you while you’re out and about. Other than that, it’s a sturdy and reliable machine that gives you quality and consistent results.
What We Liked
- Additional trays and screens for different types of dehydration

- Consistent heating throughout the levels

If you’re going to get a food dehydrator, and you know what you’re doing, don’t skimp out on quality. Go for the Excalibur model to get a high-powered machine that handles everything you need it to.
This is no beginner’s model. It’s a high output, efficient dehydration monster that can handle up to 9 trays of horizontal shelving. The rear mounted fan is a wide 7” blade. This means an even, consistent spread of warm air across each shelf.
The 26-hour timer on the adjustable thermostat means that you have complete control over when the machine has your completed food. You can set it, walk away, and come back when you’re ready to empty it.
This has 15 Sq. feet of drying space inside the machine. You’ll never be wanting for space, no matter how large your haul of fresh fruits and vegetables. The 600 Watt motor also ensures that there’s no wasted time in drying even the juiciest fruit or stickiest food.
This machine can even take homemade yogurt and speed up the fermentation process, giving you fresh, preservative-free food in record time. A quick drying time also means that you don’t lose as many nutrients in the process, preserving the natural goodness of each food you dry out.
It’s a large unit, which means that if you don’t want to take up your valuable kitchen countertops, you ought to find a dedicated space for it that won’t intrude on your daily routine. You’ll keep using it, so place it somewhere that you can easily access.
What We Liked
- High powered, high output machine
- Large capacity for any food item
- Adjustable thermostat with built-in 26-hour timer
- 9 horizontal trays for an even flow of food. No rotation needed
What We Disliked

Good for Controlled Results
For your money, you want to know that you’re getting a good product that you can rely on. That’s why we’ve included the Cuisinart food dehydrator on our list.
It doesn’t have a lot of controls. The thermostat is simply set to Low, Medium, and High, with an additional option to have fan-only for low-temp foods. But that means that you don’t have to worry about finicky outcomes or complicated read-outs. Those three settings should be able to handle just any fruit, vegetable, or herb that you need to preserve.
The Cuisinart brand helps a lot, in our opinion. These guys know how to produce an effective kitchen appliance. We’re willing to bet that you already have something Cuisinart in your home. It helps to have a trusted brand name standing behind a product that you may not be familiar with.
The online reviews are mostly excellent. The only reviews that comment negatively are about the fan. It’s not a silent machine, but if you run it while you’re out of the house, you won’t have an issue. But that’s entirely due to the fact that this machine uses an impressive 620 watts to give you completely dried food, quick. There’s no messing around here.
We also are a fan of the vertical stacking with clear trays. Check on each tray without having to lift and move the objects. It’s a good way to get a lot of dehydrating done in a short period of time.
What We Liked
- High powered machine produces results quickly
- Clear trays for easy monitoring
- Consistent results with simple controls
- Great pricing for beginner users
What We Disliked
- High powered fan produces a lot of noise
- Reduced ability to fine-tune the temperature
- No additional trays or screens
Best for Space
This is a great mid-ranged machine that should handle any size, any shape, and any food. You can do a small tray of strawberries for soup, a few trays of tomatoes to use in your cooking, or a massive tub of homemade yogurt. The large, cavernous space inside handles anything you want to dry,
And don’t worry about timing. The powerful unit can handle up to 19.5 hours of drying time, giving each food the complete treatment. This leaves no moisture at all with an effective rear-mounted fan circulating the air around each tray.
One of the best features of this dehydrator is all the accessories you can use. You get the 9 racks, a fine mesh sheet, 2 fruit leather trays, and a pair of oven mitts purpose-built for this appliance. You don’t have to upgrade to anything else because it’s all included in the one price.
Speaking of the price, it’s not the cheapest out there. But it’s also not the most expensive. For a machine this big, we would’ve expected to pay a lot more than what it’s currently listed at.
It’s not the most popular brand online, but we’ve included it on the list because of all the reviews, the majority of buyers are giving this machine top marks. For those who’ve tried it, they love it. We’re sure that you will too, for all the use you’ll get from it.
What We Liked
- Great inclusions and no need to make a secondary purchase for accessories
- Huge space inside to handle even tall items
- Multi-rack trays make for convenient drying of many varieties of foods.
