Turn on your freeze dryer and select customize. On the next screen, use the up and down arrows to adjust the drying temperature somewhere between 135F-150F (I chose 150F) and save.This will activate the candy/high temperature mode, Select start on next screen.
While your freeze dryer goes through the 15 minute cooling cycle, pour Skittles onto your lined freeze dryer trays. Do not overcrowd the trays, otherwise the Skittles will stick together.
When the cooling cycle is complete, load trays into your freeze dryer. Close and lock the door, then close the drain valve. Select continue, then touch the red slider bar to turn on candy mode. Notice the button will go from red to green. Click continue.
Next, you'll be given the option to warm trays. You can choose skip or start. I choose to skip this step, see why in pro tip below.
The next screen will show you the default drying time of 2 hours. This time can be adjusted up or down but I recommend 2 hours. Each tap brings the temperature down by 30 minutes so tap gently! When the time is up, you will be notified that the process is process complete. You can defrost or start another batch.
When the time is up, open the drain valve, then open the door and remove the trays. The Skittles outer shell should have popped, expanding the center. If needed, select extra drying time.
How to Store Freeze Dried Candy
Add cooled freeze dried Skittles to mylar bags or mason jars and toss in an oxygen absorber before sealing. For longer storage, store in mylar bags and keep in a cool, dark location.

Notes
Silicone liners or parchment paper will keep the candy from sticking to your traysand make for easy cleanup.
Although I was expecting the warming cycle to be 5 minutes, as suggested in some YouTube videos, mine took over an hour to reach 150F and I did not see an option to reduce this time. Also, some of the Skittles disintegrated and turned into a powder, so I don't recommend it.
I tried 3 different batches (30 minutes, 1 hour, and 2 hours). Some of the Skittles did not expand and get properly freeze dried using the 30 minute and 1 hour option, so I recommend sticking with 2 hours.
When buying oxygen absorbers, choose the individually packaged versus the ones that come in a pack of 10 or more. Once the packaging is opened, they begin to deteriorate.
When stored properly, freeze dried Skittles can last anywhere from 10-25 years!
Both regular Skittles and sour Skittles can be freeze dried, so try both and see which one is your favorite!
You can run up to 5 batches back to back without having to defrost the machine.
