Freeze Drying Nerds Gummy Clusters

Freeze-drying candies is not only fun but also an efficient process. Unlike fruits and other moisture-rich foods, candies require less drying time due to their lower water content and do not need to be pre-frozen. However, controlling their expansion during freeze-drying is crucial to achieving the perfect consistency and size. This often involves some trial and error to determine optimal conditions for different candy types. Researching previously successful methods and documenting each attempt will help refine your process.

Example: Freeze-Drying Nerds Gummy Clusters

Here’s a step-by-step guide on how to freeze-dry Nerds Gummy Clusters, using this colorful and popular candy as an example:

1. Prepare the Trays:

   • Distribute the candies evenly across a tray. Given their tendency to expand, a 4-tray shelf configuration is ideal, providing ample space between each shelf. Ensure each candy is spaced out to prevent sticking and overlapping.
   

2. Set Up the Freeze Dryer:

   • Connect the pump and ensure both the vacuum and drain valves are closed.
   • Close the acrylic door securely.
   • On the main screen, select 'Freeze Drying' and then choose the 'Candy' setting.
   • Adjust the shelf temperature and final drying time based on your candy type. For Nerds Gummy Clusters, set the temperature to 150°F and the drying time to 4 hours, although the default setting is typically 140°F for 3 hours.
   

3. Start the Freeze-Drying Process:

   • Press 'Start' to initiate the process. The total duration will include the predetermined final dry hours plus an additional hour.
   • To compare different setups, we conducted three cycles using the same temperature and time settings but with variations: one with parchment paper, another without, and a third with Coroplast Insulation on the sides of the shelves. Parchment paper prevents mess and facilitates easy removal of candies, although it can impede heat transfer from the tray to the candies. Insulation plates help retain heat within the shelf area, enhancing efficiency but are recommended only for candies, not items requiring freezing.
   

4. Packaging:

   • Ensure the trays are warm before opening the door to prevent condensation and facilitate easy candy removal.
   • Promptly package your candies to maintain their freshness and texture. Sealing them in airtight containers or mylar bags helps preserve their crispy texture longer.

By mastering these steps, you can efficiently freeze-dry candies like Nerds Gummy Clusters, enjoying their intensified flavor and unique, crunchy texture. Experiment with different candies and settings to discover your favorite combinations and maximize your freeze-drying success!
