Are you ready to dive into the world of freeze drying? As the ultimate food preservation method, freeze drying is a game-changer for anyone looking to build a long-term food supply. And who better to guide you through the process than us? We've been running our own freeze-drying manufacturing business since 2019, so we know a thing or two about this incredible technology.
First things first, let's break down what freeze drying actually is. Also known as lyophilization, freeze drying is a process that removes nearly all the moisture from food using a combination of freezing, heating and vacuum pressure. By removing up to 98% of the water content, freeze drying preserves food's original taste, appearance, and nutritional value while making it shelf-stable for an astonishing 25 years or more. It's like hitting the pause button on food spoilage!
So, how does it work? The freeze drying process can be broken down into three main stages:
The food is frozen to a temperature well below water's freezing point, typically between -30°F and -50°F. This ensures that all the water content is solidified.
Under vacuum pressure and using alternating heat cycles, the ice crystals in the frozen food transition directly from solid to gas, bypassing the liquid phase entirely. This sublimation process is the key to removing moisture while maintaining the food's structure.
Once the sublimation is complete, the freeze-dried food is sealed in airtight packaging, such as thick mylar bags or mason jars, to prevent moisture from re-entering and to maintain freshness. The packaging is extremely important, There are mylar bags that are thin or even have clear windows. These types of bags allow microscopic air particles to infiltrate into the bag and can destroy your freeze dried food.
Now that you understand the basics of freeze drying let's talk about how you can start preserving your own food at home. To get started, you'll need a freeze dryer machine.
