DIY Solar Dehydrators: A Guide to Preserving Food with Sunlight

In today’s world, where natural disasters and emergencies can strike at any moment, it is essential to have survival skills and disaster readiness plans in place. One of the most important aspects of survival is food preservation. In the absence of electricity or refrigeration, preserving food can be a challenge. However, with the help of DIY solar dehydrators, you can preserve food with sunlight and ensure that you have a steady supply of food during emergencies.

What is a Solar Dehydrator?

A solar dehydrator is a device that uses the sun’s energy to dry and preserve food. It is a simple and effective way to preserve food without the use of electricity or refrigeration. The dehydrator works by using the sun’s heat to evaporate the moisture from the food, leaving it dry and preserved.

Why Use a Solar Dehydrator?

There are several reasons why you should consider using a solar dehydrator to preserve your food. Firstly, it is a cost-effective way to preserve food. Unlike electric dehydrators, solar dehydrators do not require any electricity to operate, which means that you can save money on your energy bills.

Secondly, solar dehydrators are environmentally friendly. They do not produce any harmful emissions or waste, making them an eco-friendly option for food preservation.

Thirdly, solar dehydrators are easy to use and require minimal maintenance. Once you have set up your dehydrator, all you need to do is place your food inside and let the sun do the rest of the work.

How to Build a DIY Solar Dehydrator

Building a DIY solar dehydrator is a simple and straightforward process. Here are the steps to follow:

  1. Gather Materials
    • A wooden frame
    • Clear plastic sheeting
    • Black paint
    • Screws
    • Nails
    • Hinges
    • Thermometer
    • Food trays
  2. Build the Frame

    Start by building the frame of your solar dehydrator. You can use any type of wood for the frame, but cedar or redwood are good options as they are resistant to rot and insects. Cut the wood into four pieces to create a rectangular frame.

  3. Paint the Frame

    Paint the inside of the frame with black paint. The black paint will absorb the sun’s heat and help to dry the food.

  4. Attach the Plastic Sheeting

    Attach the clear plastic sheeting to the frame using screws and nails. Make sure that the plastic is tight and secure.

  5. Add Hinges and a Thermometer

    Attach hinges to one side of the frame to create a door. You can also add a thermometer to the inside of the dehydrator to monitor the temperature.

  6. Add Food Trays

    Add food trays to the inside of the dehydrator. You can use any type of food tray, but metal or plastic mesh trays work well as they allow air to circulate around the food.

  7. Place the Dehydrator in the Sun

    Place the dehydrator in a sunny location where it will receive direct sunlight. The ideal temperature for a solar dehydrator is between 110-140°F.

  8. Add Food

    Once the dehydrator is set up, you can start adding food. Fruits, vegetables, and meats can all be dehydrated using a solar dehydrator.

Tips for Using a Solar Dehydrator

  • Choose the right location: Place your dehydrator in a sunny location where it will receive direct sunlight for most of the day.
  • Monitor the temperature: Use a thermometer to monitor the temperature inside the dehydrator. The ideal temperature is between 110-140°F.
  • Rotate the food: Rotate the food trays every few hours to ensure that the food dries evenly.
  • Store the food properly: Once the food is dry, store it in airtight containers in a cool, dry place.


In conclusion, a DIY solar dehydrator is an excellent tool for preserving food with sunlight. It is a cost-effective, environmentally friendly, and easy-to-use option for food preservation. By following the steps outlined in this article, you can build your own solar dehydrator and ensure that you have a steady supply of food during emergencies. Remember to choose the right location, monitor the temperature, rotate the food, and store the food properly to get the most out of your solar dehydrator.
