I bought my first dehydrator about 7 years ago from a thrift store. It turned out to be one of the best things that I’ve ever bought.
Thanks to my dehydrator, I’ve been able to do things like:
- Make my own MREs and backpacking meals
- Preserve surplus food from my garden
- Save money by buying produce in season and then dehydrating it for times when it is pricier
- Build up a stockpile of emergency foods
But, after 7 years, my dehydrator has taken a beating and some of the trays are cracked.
I’ve honestly been thinking about buying a new dehydrator for years, but I don’t like to buy something new when the old one is still working perfectly well!
There is simply too much waste in the world with people buying the “newer and shinier” versions that they don’t actually need (Yep, I’m thinking of you iPhones!).
I digress.
Now, you can find all sorts of lists of the best dehydrators of the year. But our goal is to find the best dehydrator for you.

What to Consider When Choosing
Tray vs Shelf
All modern dehydrators can be broken down as either stacking tray dehydrators or shelf dehydrators. Each type has its pros and cons.
Tray Dehydrators
These are the most common dehydrators and are generally very affordable.
They have trays which stack on top of each other. The trays have holes in them so air can flow through. A center hole serves as a channel to ensure air gets to all of the trays.
The heating device and fan are either located at the top or the bottom.
Pros
You can adjust the number of trays- Some models can hold lots of trays to dehydrate lots of food at once
- Are usually smaller, so good for people pressed for space
Cons
- The trays closest to the heater tend to dehydrate fastest; you’ll have to rotate the trays for even dehydrating
- You have to unstack the trays to see whether the food is done
- If the heater is on the bottom, juices from the food can drip down on it
Shelf Dehydrators
These dehydrators look like mini ovens with lots of racks inside them. At the back there is a heater with a fan to blow warm air over the food.
Pros
- Because the heater is located at the back, the air flow is distributed horizontally across the shelves for even drying
- Shelves can be pulled out easily to check on the food
- You can put thicker foods into one, such as whole bananas
- You can use them to make yogurt
- There is no air channel in the middle, so it is easier to dehydrate liquids like tomato sauce
Cons
- You can’t adjust the number of shelves
- They are harder to clean
- They tend to be pricier
- They take up more space
Capacity
The capacity of a dehydrator is usually measured by the number of shelves or trays it has. However, the capacity of two different 7-tray dehydrators can be very different depending on the tray sizes.
If you only plan to do occasional dehydrating (such as for making camping meals), then a smaller model dehydrator will be fine.
If you will have a lot of food at once to dehydrate (such as from your garden), then go for a larger model.
Temperature
Some cheap dehydrators don’t even have temperature controls. Avoid these at all cost!
Without the temperature controls, you’ll be limited to what types of recipes you can make. Also, no temperature controls is a sign of a bad-quality dehydrator.
Most dehydrators will reach 140 ° F. However, even quality dehydrators will fluctuate a bit in temperature.
Thus, if you want to make jerky, it is best to get a dehydrator with a temperature of 155° F or above.
Air Flow
It is hard to determine which dehydrators have good air flow design and quality heaters just by looking at them. Even if you read the manufacturer’s description on websites, it still won’t give you much (unbiased) info.
Instead, consider looking at the reviews on sites like Amazon. The numbers of stars will give you an idea of the quality.
Noise
I have a separate pantry where I do my dehydrating, so noise don’t really bother me. However, the noise can drive you crazy if it’s near your living space!
Good dehydrators will have their decibel rating listed. Choose a low rating if noise matters to you.
Cool Features to Have
- Clear Trays: If you get a stackable tray dehydrator, go for clear shelves. You’ll be able to check on the food easier without having to lift all of the trays.
- Timers and Auto Shutoff: Because dehydrating food takes hours, you might forget about it and end up with overly-dehydrated food. These features prevent that from happening.
- Multiple Temperature Settings: Only really advanced dehydrators (like the Excalibur model listed below) have this feature. It allows you to set one temperature and then switch to another temperature after a specific amount of time.
- Dishwasher Safe: Dehydrators get sticky, so you want trays or shelves which can be cleaned easily.

Cons
- Other than the price, there is nothing wrong with this dehydrator!
Nesco Snackmaster
Best For: People who occasionally dehydrate food and want a quality yet affordable dehydrator.
Pros
- Top mounted fan reduces mess
- 600 watts of drying power
- Adjustable temperature from 95 to 160 degrees

Hanging Pantry System
Best For: People who want to experiment with solar dehydration but don’t want to build their own system (the trays on this are great and would be hard to make yourself)
Pros

- No noise
- Keeps insects out
- Trays are perforated for better air flow
Cons
- Kind of pricy for something you could easily make yourself
- Frustrating design makes it difficult to set shelves up
Don’t Forget about Mylar Bags and Oxygen Absorbers!
If you want to use your dehydrator to dry foods for long-term storage, then you will have to seal them in mylar bags with oxygen absorbers.
The oxygen absorbers remove oxygen which would cause spoilage. The mylar bag prevents light, moisture, and oxygen from getting in.
For an extra level of protection put the sealed mylar bags into buckets. The buckets will keep them safe from rodents, insects, flood water, and other damage.

I have a Presto 6300 and a 6301. They are both the round stackable tray machines. I rarely, if ever, see a review of the Presto Dehydrators. The 6300 I purchased from Amazon for $35. it did not have a temperature gauge, it was permanently set at 140 deg. I wanted more, so I also bought the 6301 for about $65. It has a timer and a temperature setting knob. I use both and put the appropriate foods in the 140 deg fixed setting machine, and use the other for everything else. I love my Prestos. Have you checked these machines? Very reasonable and easy to use, wash and store.
No haven’t used a Presto before but thanks for the heads up, sounds like a decent option.
I used a stackable dehydrat or with no temp control for years then upgraded to an Exca liber shelf unit. I love it and have had for 15 years! These last a long time so you can look at them as a long term investment.
Thanks for this info I now know what too look for.
Re: the xxxxx, I was reading the questions & reviews for it and stumbled across this info for making jerky in the 95°F- 158°F temp range:
Question: So my jerky is supposed to be cooked at 165 so many are set to only go to 158 ? Help please
Answer: It only goes to 158 but their directions say after the required time, to remove jerky and put into a preheated 250-275 degree Oven for 10 mins and then return to dehydrator trays to cool completely.
Thought this was an interesting workaround.
I need to know how to make a solar drier.
Hi.. no mention importance of wattage? Varies greatly for some reason, yes.
High wattage will heat up faster (which is important if you want to dehydrate meat or dairy). High wattage also usually means a stronger fan, so the drying is usually better. However, high wattage isn’t really that important when drying smaller amounts of food or things which dry quickly anyway (like greens or thinly-sliced fruit) so you just end up using more energy unnecessarily. So, I wouldn’t worry too much about wattage. The Excaliber only has 600 watts and does a great job of drying foods.
