Preparing blueberries for dehydrating

Before you can start dehydrating the blueberries, you need to prepare them.

Prepare to dehydrate blueberries

  • Clean the blueberries in a bowl. Take out any stems or bad berries.
  • Please put them in hot water for 30 seconds. They will start to crack.
  • Next, please put them in cold water for 30 seconds.
  • Take them out and let them sit until they’re dry.
  • Now, you can dry the blueberries using a machine like a dehydrator, an air fryer, or an oven. Just follow the instructions for each one.

Method 1: Dehydrate blueberries in a food dehydrator

The best way to dehydrate blueberries or any fruit is by using a food dehydrator. I have a Nesco dehydrator. It’s simple, easy to clean, and I can adjust the temperature, plus it has a fan. For the price, it’s perfect.

Here’s how you can dehydrate blueberries:

Dehydrate blueberries on trays

  • Lay them out on the dehydrator trays, just one layer.
  • If your dehydrator comes with a screen, use it. It helps when the berries shrink and might fall through. Alternatively, you could put a sheet of parchment paper in the tray.

  • Set your dehydrator to 115 degrees Fahrenheit. If it doesn’t have a temperature control, switch it on. Let the blueberries dry for about 18 to 24 hours.
  • But start checking on them after every few hours.

Method 2: Dehydrate blueberries in an air fryer

  • Use your air fryer if you have a small amount and no dehydrator.
  • Put the blueberries in the air fryer, but don’t let them pile up. One flat layer is best.
  • Set your air fryer to 120 degrees.
  • Please leave them in there for 15 hours. After 10 to 12 hours, check them to see if they’re dry.

This way, drying blueberries in your air fryer is easy to understand!

Method 3: Dehydrate blueberries in the oven

Suppose you don’t own a food dehydrator, no worries! You can still dry blueberries in the oven. It’s a suitable method, though it uses more electricity.

Here’s how you do it:

  • Cover a cookie sheet with parchment paper. Then, spread out your blueberries in a single layer.
  • Set your oven to 135 degrees Fahrenheit and let them bake for 10 hours.
  • If you’re in a hurry, bake them at 200 degrees Fahrenheit for 7 hours instead. Just keep an eye on them so they don’t burn.
