Have you ever wished you could keep your garden’s summer harvest fresh all year long? Or maybe you want to stock up on healthy, homemade meals that last for decades without taking up freezer space? That’s where freeze drying comes in—a game-changer for food preservation.
If you’ve never heard of a freeze dryer before, don’t worry! I’ll walk you through exactly how they work and why Harvest Right freeze dryers are the best option for home use.
What is Freeze Drying?
Freeze drying (also called lyophilization) is a process that removes moisture from food while keeping its taste, texture, and nutrients intact. Unlike dehydrating, which uses heat to remove moisture (and can sometimes affect flavor or texture), freeze drying locks in all the goodness without cooking the food.
This means freeze-dried strawberries still taste like strawberries, not chewy fruit leather. And freeze-dried homemade soup? Just add hot water, and it’s as good as fresh!
How Does a Freeze Dryer Work?
A freeze dryer might sound like a complicated machine, but the process is actually pretty simple. Here’s how it works in a few easy steps:
Step 1: Freezing
The first step is to freeze the food. In a Harvest Right freeze dryer, this happens automatically. The machine drops the temperature to as low as -40°F to ensure all the moisture in the food turns into ice.
Step 2: Creating a Vacuum
Once the food is completely frozen, the freeze dryer creates a vacuum inside the chamber. This vacuum is important because it allows the next step—sublimation—to happen.
Step 3: Sublimation (Ice to Vapor)
Here’s the cool part: instead of melting into a liquid, the ice inside the food skips the liquid stage and goes straight to gas. This is called sublimation.
The freeze dryer gently applies a small amount of heat to encourage sublimation. The ice turns into water vapor and gets sucked out of the chamber, leaving the food perfectly dry but still looking exactly the same as when it started.
Step 4: Final Drying
After most of the moisture is gone, the freeze dryer increases the temperature a little more to remove any last bits of water. When the process is done, the food is completely dry, lightweight, and ready to be stored for up to 25 years if kept in airtight packaging!
