Ever since I was little I can remember my parents dehydrating things like apples and strawberries. My parents would lightly sprinkle things like cinnamon and sugar or different flavors of Jell-O on top of the apples and the whole house would smell so good as they dried. All I knew about dehydrating then was there was going to be a yummy treat the next night. I was excited to learn about dehydrators when I decided to dehydrate my own foods. Dehydrators have changed quite a bit since then. They are much more efficient and user-friendly and take up much less space.
I will help you learn what you need to know about food dehydrators so that you will know exactly which one to buy.

Top 10 Food Dehydrators Compared
We spent hours comparing and testing these top 10 food dehydrators and have broken down the info by budget, wattage, # of trays, timer type, thermostat type, flow type, and safety.
What is Dehydrating?
Dehydrating is a form of food preservation that uses a combination of heat, fans, and vents to remove the moisture in foods to an extremely low level. Dehydrating removes 85-95% of the moisture which aids in improving the shelf life by hindering the growth of bacteria, mold, and yeast all while maintaining up to 50% of the nutritional value. See USU for more information on dehydrating.
5 Reasons You Need a Food Dehydrator
- So you can build a shelf-stable supply of food and snacks that can store for a year or longer.
- For emergencies, travel snacks, camping, and backpacking.
- To give you more control over your nutrition and what is in your food and snacks.
- So that you can preserve your garden or store-bought produce and consume it all year.
- To help you be more self-sufficient and prepared in a world of rising food prices and unpredictable markets.
What Are the Different Types of Food Dehydrators?
There are two different types of home dehydrators.
- Vertical flow
- Horizontal flow
Vertical flow machines are usually stackable machines with the heat source in the bottom. These machines are a more affordable option and take up less counter/storage space.
Vertical flow machines tend to dry slower than horizontal flow machines and may require you to rotate trays as you go. This is just because of the construction of the machine with the heat source at the bottom. The top trays won’t get as much heat as the bottom trays so rotating trays partway through can help with drying time.
These machines are most commonly used for fruits and vegetables but don’t work as well for meats.
Horizontal flow machines have a more even flow of air through the trays with the heat source in the back of the machine.
While these machines are more expensive and can take up more counter space, horizontal flow machines’ drying time is generally faster than vertical flow machines.
Horizontal machines do however cost more and take up more counter/storage space but are more commonly used for meat as well as heartier vegetables and bigger batches.
How much does a food dehydrator cost?
The cost of home food dehydrators ranges anywhere from $40 for small vertical flow units up to $600 for commercial-sized units. The price depends on the type and size of the dehydrator you want to get. Vertical flow dehydrators are generally cheaper. For most home food dehydrators you can expect to spend anywhere from $50 to $200.
What Does a Food Dehydrator Do and What Features Can It Have?
Dehydrating uses low heat (between 130*- 167* F) combined with a steady flow of air through vents and fans to circulate the air for an extended period of time to remove moisture from food by evaporation.
The warm air flowing over the food speeds up surface evaporation while the warm temperature of the food causes it to release moisture from the inside. Because of the low heat temperature, it does not cook the food, it just releases moisture to aid in the evaporation process.
Dehydrators Come With Different Features
Dehydrators can come with different features that can be helpful when dehydrating the different foods that you like. As you would expect, the more features a dehydrator has the more likely the price will be higher.
Dehydrator Features can include:
- Adjustable Timer
- Adjustable temperature
- Tray Capacity
- Mesh sheets
- Fruit roll sheets
- Dishwasher safe trays
- Clear plastic/glass to easily see food while drying
What to Look for When Buying the Best Food Dehydrator for You
The 4 things you should look for when picking a dehydrator are
- How many shelves and what size do you want
- How often you are going to use it
- The amount of counter space you have available
- Vertical or horizontal flow
1. How many shelves and what size do you want – The amount of food you want to dehydrate will help you decide what size dehydrator you will want to get. If you want to do bigger batches to build food storage you’ll want to get a bigger dehydrator.
2. How often you are going to use it – If you just want to use it for snacks here and there a smaller dehydrator will work great. Purchasing pre-packaged dehydrated foods can be expensive so even if you plan on just using a dehydrator a handful of times a year it can still be cheaper than buying pre-packaged dehydrated foods.
3. The amount of counter space you have available – If you live in a smaller house or apartment and don’t have a ton of space a smaller dehydrator would probably be better. If you have space in your garage you could potentially fit a commercial-size dehydrator that can help produce a large amount of dehydrated food at a time.
4. Vertical flow or horizontal flow?
Vertical flow is usually less expensive and has lower wattage. It has a heating element and fans at the bottom of the unit. This usually causes the bottom shelves to dry faster than the top shelves so it will require you to rotate the shelves to get all shelves evenly dehydrated.
Horizontal flow is usually more expensive and has a higher wattage. It has a heating element and fans in the back of the unit which creates a more even airflow and is more efficient.

Is buying a food dehydrator worth it?
Buying a home dehydrator is worth the cost for anyone who wants to provide a wide variety of shelf-stable foods as snacks or for long-term storage. While maintaining at least 50% of the nutrients these foods can be stored in airtight mylar bags, jars, or air-tight containers. Dehydrated foods make great healthy snacks as well as great long-term food storage when stored properly.
- Interested in making healthy dehydrated foods for snacks
- Interested in storing food long term
- You want to have complete control over what foods you are dehydrating and storing
- You want to store foods that can last on your shelf for 5+ years when stored properly. 30+ years if stored vacuum sealed
- You have the space to store dehydrated foods in your pantry, storage room, closet, or other areas.
- You like to be prepared with food storage on hand
Not worth it:
- You don’t plan to use it regularly
- You don’t have access to fresh produce
- You don’t have extra room to store food long term
How long does dehydrating take?
Dehydrating food can take anywhere from 5-38 hours. There are a few different factors that come into play when deciding how long dehydrating will take.
- Thickness/Moisture level
- Machine Wattage
- Type of Dehydrator
1. Thickness/Moisture level – Depending on the thickness and amount of moisture the food item you are dehydrating contains, your time can be longer or shorter than the recommended times. Refer to the manual that comes with your specific dehydrator for recommended times based on specific foods.
2. Humidity – The humidity level of your home can be a big factor in dehydrating times. The higher the level of humidity the longer it will take. The less humidity the less time it will take. Things that can affect the humidity are rainy or stormy weather, using a swamp cooler instead of air conditioning, and the climate where you live in general.
3. Machine Wattage – The wattage of your machine can determine the amount of time it takes. The lower wattage the longer it will take. The higher the wattage the faster it will be. This does not mean you need a bigger higher wattage machine. You may just need to do smaller batches or it might take a little longer to dry.
4. Temperature – Some dehydrating machines let you have control of the temperature. This may be desirable for some. All foods dehydrate at different temperatures. If you plan on doing a wide variety of food you’ll want an adjustable thermostat. If your machine doesn’t let you adjust the temperature, and it doesn’t say in the manual you can use an oven thermometer to test the temperature so you know where your machine sets the temperature.
5. Type of Dehydrator – There are two types of home dehydrators. Vertical flow with the heating element in the bottom of the machine and horizontal flow with the heating element in the back of the machine.
