  • Grapes ( as per your choice)
  • Vinegar ( for cleaning and washing)

How to prepare dehydrated grapes or raisins

The total dehydration process can be divided into two sections – preparing the grapes and then dehydrate. I will discuss these two steps separately for ease of your understanding.

Preparing the grapes

Clean and wash the grapes properly before doing anything. You may wash it with tap water. You may also use a scrub brush. To clean the grapes more appropriately, you may also use white vinegar or apple cider vinegar. If you have apple cider vinegar at home, then add 10 parts of water with 1 part of the vinegar to make the solution. After making the solution, let the grapes sit for 5 minutes in it. If you are using white vinegar, then add 3 parts of water with 1 part of the vinegar and let the grapes sit for 10 minutes.


After the washing is done, remove the grapes from the stems. Now you can dry them up at room temperature to get away with the water on the surface of the grapes. However, it is optional as you know the water will be dried up anyway when you start dehydrating it. Finally, if you are using seeded grapes then cut them into two and remove the seeds.

Dehydrating grapes with the air fryer

  • Put the grapes in a single layer on the basket of the air fryer. If you have an air fryer with racks having multiple layers, then utilize all the layers to maximize the capacity. You can allow the grapes if they touch another but do not allow multiple stacking.
  • Now move on to the most important part of dehydrating – parameter setting. Set the temperature at 135F. You may expect that the whole process will take between 24 to 48 hours. It is difficult to say exactly how much time it takes. Because of the quality of the grapes and the quality of the air fryer, cooking time may vary.
  • If you want to make the time shorter then set the temperature at 145F and let the grapes dehydrate for around 12 hours. Then set the temperature at 135F for the rest of the time.
  • During the process, grapes will release water that may create a sticking problem. To prevent the grapes from sticking, shuffle every 6 to 8 hours.
  • To know when to stop, you should taste the raisins when you feel that they are done. If you have doubts, then stop the air fryer and leave it for 30 minutes. After that taste raisins and if you are not satisfied, continue for another few hours.

Is it possible to dehydrate grapes with my air fryer?

It is a common question people ask while dehydrating foods with the air fryer. Food dehydration needs a lower temperature. Therefore, a perfect air fryer that can be used as a dehydrator should have a lower operating temperature of around 100°F. In our specific case of dehydrating grapes, the required temperature is 135°F. We know that a typical air fryer may have a temperature range of 170°F to 400°F. But you may also find an air fryer with a wider temperature range that can be used as a dehydrator.

You may read our article to get an idea about some awesome air fryers with a dehydrator option. If you like a regular size air fryer for a medium to a large family, then you can go for Chefman 6.3 qt air fryer that can give you a temperature of 90°F. But if you are looking for a higher capacity, then I would recommend GoWise 17 qt air fryer with multiple racks. The best of this unit is the timer setting of up to 8 hours that is very important for food dehydration. Other than these, it comes with 5 layer racks that are very uncommon for an air fryer. It also has multiple cooking options including rotisserie.

Bottom line

I think now you can prepare your dehydrated grapes at home with the dehydrator. Do not try it if your air fryer does not give you the required temperature. If you try to dehydrate at a higher temperature, then the nutrition content of the food will get destroyed. You may not store the foods for a long time if they are dehydrated in a wrong process with a wrong air fryer.
