Air fryers have revolutionized the way we cook, offering a healthier and quicker alternative to traditional frying. But their versatility extends beyond just crispy fries and juicy chicken. Many home cooks are now wondering: can I use my air fryer as a dehydrator? The short answer is, it depends. Let’s dive into the details and explore the possibilities, limitations, and everything you need to know about using your air fryer for dehydration.
Understanding Air Fryers and Dehydrators: Key Differences and Similarities
To determine if an air fryer can effectively function as a dehydrator, we need to understand what each appliance does and how they work.
How Air Fryers Work
Air fryers use rapid air circulation technology to cook food. A heating element generates heat, and a powerful fan circulates this hot air around the food, creating a crispy exterior similar to deep frying but with significantly less oil. This process is known as convection cooking. Key features of air fryers include: a heating element, a fan, and a cooking basket or tray.
How Dehydrators Work
Dehydrators, on the other hand, are specifically designed to remove moisture from food. They use a low, consistent temperature and a fan to circulate air, gradually drying the food over several hours. This process inhibits the growth of bacteria, yeasts, and molds, preserving the food for extended periods. Dehydrators typically feature multiple trays to maximize the surface area for drying and precise temperature controls.
Similarities and Differences: A Head-to-Head Comparison
While both appliances utilize hot air and a fan, the crucial difference lies in their primary function and design. Air fryers are designed for quick cooking at higher temperatures, while dehydrators are built for slow, even drying at lower temperatures. Air fryers prioritize speed and crispness, while dehydrators focus on moisture removal and preservation. Another key difference is in temperature control. Dedicated dehydrators usually have very precise temperature control, going as low as 85-90°F, while air fryers often struggle to maintain such low temperatures.
Can Your Air Fryer Actually Dehydrate Food? Assessing Compatibility
Whether or not your air fryer can effectively dehydrate food depends largely on the model you own. Some air fryers are specifically designed with a dehydration function, while others may not be suitable for this purpose.
Air Fryers with a Dehydrate Function
Certain air fryer models come equipped with a “dehydrate” setting. These models are specifically designed to maintain low temperatures (often between 90°F and 170°F) and circulate air for extended periods, mimicking the function of a traditional dehydrator. If your air fryer has a dedicated dehydrate setting, it’s the best option for attempting to dehydrate food. These air fryers often come with multiple racks, similar to a dehydrator, to maximize the drying surface area.
Air Fryers Without a Dehydrate Function
If your air fryer doesn’t have a dedicated dehydrate setting, you can still potentially use it to dehydrate food, but with some limitations. You’ll need to be able to set the temperature to the lowest possible setting (ideally below 200°F) and monitor the food closely. It’s crucial to ensure the temperature is low enough to prevent cooking the food instead of drying it. The success of this method will depend on your air fryer’s ability to maintain a consistent, low temperature for an extended period.
Factors to Consider: Temperature Control, Airflow, and Capacity
- Temperature Control: The most important factor is the air fryer’s ability to maintain a low and consistent temperature. Dehydration requires temperatures between 95°F and 165°F.
- Airflow: Adequate airflow is essential for removing moisture. Ensure the air fryer has sufficient ventilation.
- Capacity: Air fryers typically have a smaller capacity than dedicated dehydrators, so you may need to dehydrate food in batches.
How to Dehydrate Food in an Air Fryer: A Step-by-Step Guide
If you’ve determined that your air fryer is suitable for dehydration, follow these steps to achieve the best results.
Preparation is Key: Slicing and Pre-Treatment
- Choose Your Food: Fruits, vegetables, and meats can all be dehydrated.
- Slice Evenly: Cut the food into thin, uniform slices (about 1/8 to 1/4 inch thick) to ensure even drying. A mandoline slicer can be helpful for this.
- Pre-Treatment (Optional): Some fruits, like apples and bananas, may benefit from pre-treatment to prevent browning. This can involve dipping them in lemon juice or ascorbic acid solution.
Setting Up Your Air Fryer for Dehydration
- Prepare the Racks: Lightly grease the air fryer racks or use parchment paper liners with holes to prevent sticking.
- Arrange the Food: Spread the slices in a single layer on the racks, ensuring they are not overlapping.
- Set the Temperature and Time: Set the air fryer to the lowest possible temperature (ideally between 95°F and 165°F). If your air fryer doesn’t go that low, use the lowest setting and prop the door open slightly to allow for more air circulation. Start with a time of 2-4 hours and adjust as needed.
Monitoring and Adjusting During Dehydration
- Check Regularly: Check the food every hour or two to monitor the drying progress.
- Rotate Racks: Rotate the racks to ensure even drying, especially if your air fryer has uneven heat distribution.
- Adjust Time and Temperature: If the food is drying too quickly or too slowly, adjust the temperature or time accordingly.
- Test for Doneness: The food is done when it is leathery and pliable, with no visible moisture.
Tips for Success
- Experiment: Dehydration times can vary depending on the food, thickness of slices, and your air fryer model. Experiment to find the optimal settings for your specific appliance.
- Use a Thermometer: A separate oven thermometer can help you monitor the actual temperature inside the air fryer, especially if your air fryer’s temperature settings are inaccurate.
- Proper Storage: Once the food is dehydrated, allow it to cool completely before storing it in airtight containers in a cool, dark place.

Is Using an Air Fryer as a Dehydrator Right for You? A Final Assessment
Ultimately, the decision of whether or not to use your air fryer as a dehydrator depends on your individual needs and circumstances.
If you have an air fryer with a dedicated dehydrate function, or one that can maintain a low, consistent temperature, it can be a convenient way to dehydrate small batches of food. However, if you plan to dehydrate frequently or in larger quantities, a dedicated dehydrator may be a better investment. Consider your budget, space constraints, and frequency of use when making your decision. Also, remember that there are some foods that dehydrate better in a true dehydrator, such as fruits with high water content.
Can all air fryers be used as dehydrators?
Most air fryers are not specifically designed for dehydration. However, many models, especially those with larger capacities and adjustable temperature settings (often down to around 135°F or 57°C), can be used for dehydration purposes. These air fryers typically offer a “dehydrate” function or the ability to set very low temperatures for extended periods, mimicking the process of a dedicated dehydrator.
Before attempting to dehydrate in your air fryer, consult the user manual. It will specify the temperature range and whether the appliance is suitable for dehydration. If your air fryer lacks a low-temperature setting or doesn’t mention dehydration, it’s best not to use it for this purpose, as higher temperatures can cook the food instead of drying it.
What are the benefits of using an air fryer as a dehydrator?
Using an air fryer as a dehydrator can be a space-saving and cost-effective option, especially if you already own one. It eliminates the need to purchase a separate dehydrator appliance. Furthermore, air fryers generally heat up and dehydrate food faster than traditional dehydrators due to the concentrated airflow and smaller cooking chamber.
The compact size of an air fryer also makes it easier to dehydrate smaller batches of food, which is ideal for those who only need to dehydrate occasionally or want to experiment with different ingredients. The relatively quick dehydration time can also save on energy costs compared to using a larger, dedicated dehydrator for small quantities.
What foods can you dehydrate in an air fryer?
A wide variety of foods can be successfully dehydrated in an air fryer. Fruits such as apples, bananas, berries, and mangoes are popular choices. Vegetables like tomatoes, peppers, zucchini, and onions can also be dehydrated for use in soups, stews, or as snacks.
Beyond fruits and vegetables, you can dehydrate jerky from lean meats like beef or turkey. Herbs such as basil, oregano, and rosemary can be dried for long-term storage. Even fruit leather and pet treats can be made in an air fryer with the right technique and preparation.
How do you prepare food for dehydration in an air fryer?
Proper preparation is crucial for successful dehydration in an air fryer. Start by thoroughly washing and cleaning your chosen food items. Then, slice the food into thin, even pieces, ideally about 1/8 to 1/4 inch thick. Uniformity in size and thickness is essential for even drying.
For fruits, you might consider pretreating them with lemon juice or ascorbic acid to prevent browning. For meats, marinate them according to your jerky recipe. Arrange the prepared food in a single layer on the air fryer basket or racks, ensuring there’s enough space for air circulation. Avoid overcrowding the basket, as this can hinder the drying process.
What temperature and time settings should I use for dehydrating in an air fryer?
The optimal temperature for dehydrating in an air fryer typically ranges between 130°F and 170°F (54°C to 77°C), depending on the food type and the model of your air fryer. Lower temperatures are generally preferred for delicate items like herbs, while slightly higher temperatures can be used for meats and some vegetables.
The dehydration time can vary significantly, from a few hours for thin slices of fruit to 8-12 hours for jerky. Start by checking the food’s progress after a few hours and adjust the time and temperature as needed. Remember that proper dehydration occurs when the food is leathery or brittle, with no visible moisture remaining.
How do I ensure even drying when using an air fryer for dehydration?
Ensuring even drying in an air fryer requires a few key techniques. First, make sure all the food slices are of uniform thickness and size. Arrange them in a single layer on the air fryer basket or racks, leaving space for air to circulate freely around each piece. Avoid overcrowding the basket.
Rotate the food or the racks periodically during the dehydration process. This helps to ensure that all sides of the food are exposed to the hot air evenly. Additionally, if your air fryer has a “dehydrate” function, it will likely cycle on and off to maintain the low temperature and airflow necessary for even drying.
What are the potential drawbacks of using an air fryer as a dehydrator?
One potential drawback of using an air fryer as a dehydrator is its limited capacity. Air fryers typically have smaller baskets or racks compared to dedicated dehydrators, which means you can only dehydrate smaller batches of food at a time. This can be time-consuming if you need to dehydrate larger quantities.
Another potential issue is temperature control. Some air fryers may not have precise temperature settings or consistent temperature distribution, which can lead to uneven drying or even cooking of the food. It is also essential to consider energy consumption. While air fryers dehydrate faster than traditional dehydrators, running the appliance for several hours at a time can increase your electricity bill.
