What is a Solar food dehydrator?

A solar food dehydrator is a device used to remove moisture from food using the power of the sun. The result is dried food that can be stored for long periods without spoiling. Solar food dehydrators are a low-cost alternative to electric food dehydrators. They are the secret to boosting the nutrient density of your preserved goods. 

Our easy-to-follow movies and plans will guide you through each step of the building process, ensuring that you end up with a high-quality and functional food dehydrator. Your family's food security depends on it!

how Does it work?

In our solar food dehydrator design, air enters the bottom of the solar air collector. The heated air then flows into the top of the drying chamber, falls down and across the shelves … all the way down, and then flows up through a 'chimney' which is separate from the main drying chamber. This works with the natural tendency of cool air to sink and warm air to rise, so it results in better, more consistent airflow … and thus, more efficient & faster drying.

A preppers must-have! With our easy-to-build plans, you'll be able to preserve your own food without relying on electricity or fuel and at the same time, save money on groceries.

 Our supersized solar food dehydrators are a must-have for off-grid living!

The food dehydrator is so cool and it is still going strong after 5 years in the weather. I love that I can dehydrate so much food at once. Anyone who loves to eat farm fresh produce needs to get one of these to preserve their harvest. It's "the bomb!" Saves my food and saves my money!

Erica Wisner

This is the sturdiest solar food dehydrator I have ever built. Typical solar dehydrators just don't cut it for homesteaders. This is the homesteader's best friend for keeping food for longer.

I have some experience with home-built solar dehydrators and the solar dehydrator at Wheaton Labs is the best and most efficient design I've ever used.  It is able to dry three pounds of fruit on a single screen and can hold 18 screens.  The hot summer sun keeps the unit warm and dries food evenly and quickly. It also works great going into the fall as fruit harvests increase.

what's in the plans?


The Wheaton ATC1 food dehydrator model has an extended solar collector, allowing for faster drying.

what's in the movies?

Solar Food Dehydrator Movie

Man building a food dehydrator

This HD video is 1 hour 21 minutes long and includes discussion over the general design that was decided on, an then some of the problems that were experienced during the build. This movie complements the Wheaton ATC1 and Missoula solar food dehydrator plans.

Free Heat Movie

Free Heat is a 2 hour 18 minute film that explores the world of rocket mass heaters, a highly efficient and radical type of wood-burning technology. The movie follows the experimentation and implementation by a team of experts working on various types of rocket mass heaters, including the Rocket Assist solar food dehydrator. Whether for heating a home, cooking a meal, or creating a relaxing sauna experience, rocket mass heaters are a versatile and efficient technology for self-sufficiency. This movie complements the Rocket Assist solar food dehydrator plans.

How much food can I dehydrate in the solar food dehydrator?

Our solar food dehydrators can dry large amounts of food quickly. They have 18 trays and each tray is about 18" by 24" and able to dry about 3 lbs of vegetable/fruit, for a total of 54lbs. 

How long does it take to dehydrate food in this solar food dehydrator?

Drying time may vary depending on the your location, weather conditions and what you are drying. But typically, you can expect the food to be dried in 1 or 2 days.

Why are our solar food dehydrators the best?

These 3 models of solar food dehydrators are the result of many years of testing and re-designed and more testing to increase the performance, make it easier to use, more simple and low cost to build.

Dehydrating is a great way to preserve produce but direct light can lead to nutrient loss. Our solar food dehydrator design uses indirect heat from the sun – the food is dried by solar-heated air – leading to sun-dried deliciousness with maximum nutrient density retained!

How much will it cost to build the solar food dehydrator?

This will vary, depending on how much you are able to use reclaimed materials or if you have to buy new.

It looks complicated! Can I really build it myself?

Yes, absolutely! There are detailed plans, cut lists and assembly instructions. The videos  are also very helpful. If you get stuck, help can be found in the forums at https://www.permies.com
