how to make a food dehydrator from a refrigerator



Food dehydration is a common method used for preserving food by removing its moisture content. One of the most popular ways to achieve this is by using a food dehydrator. However, purchasing a commercial dehydrator can be costly. Fortunately, with a little creativity, you can make your own food dehydrator from a refrigerator. In this article, we will discuss the step-by-step process to transform your refrigerator into a functional food dehydrator. Let's dive in!

1. Gathering the materials:

To begin with, you will need a few materials to convert your refrigerator into a dehydrator. Make sure you have the following items on hand:

- An old refrigerator: preferably one that is no longer in use and can be repurposed.

- Shelves or mesh racks: to place the food on while it dehydrates.

- A fan: to circulate the air inside the fridge evenly.

- A heating element: to generate the required heat for dehydration.

- Thermometers: to monitor the temperature accurately.

- Silicone or food-grade sealant: to seal any gaps or holes in the fridge.

2. Preparing the refrigerator:

Before starting the conversion process, thoroughly clean the refrigerator. Remove any unwanted odors, mold, or dirt that might contaminate your food during dehydration. Additionally, ensure that all shelves, drawers, and compartments are removed, providing ample space for the food you'll be dehydrating.

3. Installing the fan and heat source:

Position the fan in a way that it can effectively circulate air throughout the fridge. For better airflow, consider attaching it to the inside back wall. Depending on the size of your refrigerator, you may need multiple fans for optimal air circulation. Next, install the heating element inside the fridge. This could be a small heater or a heating coil that can produce a gentle and consistent level of heat.

4. Creating air vents:

To allow the air to flow freely and maintain a consistent temperature, you need to create air vents in your refrigerator. Drill small holes near the top and bottom of the fridge, ensuring they are evenly spaced. These vents will allow fresh air to enter the dehydrator while pushing out any excess moisture in the process.

5. Monitoring the temperature:

It is crucial to monitor the temperature accurately while dehydrating your food. Place thermometers inside the fridge at different locations to ensure that the heat is evenly distributed. This helps prevent overcooking or undercooking your food. Adjust the heat source accordingly to maintain a consistent temperature throughout the dehydration process.

6. Adding the food:

Now that your refrigerator is ready, it's time to load it up with food for dehydration. Cut the food into thin, uniform slices or small pieces to ensure even drying. Place the food on the shelves or mesh racks, ensuring sufficient space between each piece for proper air circulation.

7. Sealing any gaps:

To minimize heat loss and maintain a stable temperature inside the dehydrator, seal any gaps or holes in your refrigerator using silicone or food-grade sealant. This step will help in retaining the heat and enhance the overall efficiency of your DIY food dehydrator.

8. Rotating and checking the food:

Throughout the dehydration process, it's crucial to periodically rotate and check on the food. This ensures that all pieces are drying evenly. Some foods may require longer drying times, so be patient and monitor their progress. Remember to keep the door closed as much as possible to maintain a consistent temperature.


With some simple modifications and a little DIY spirit, you can transform your old refrigerator into a versatile food dehydrator. By following the steps outlined in this article, you can effectively dehydrate a variety of foods to enjoy their extended shelf life and intense flavors. So, roll up your sleeves, repurpose that old fridge, and embark on a rewarding food dehydration journey!
