A freeze dryer is a machine that helps you preserve food by removing as much moisture content and while retaining its physical characteristics. In effect, you get a longer storage life without altering any flavors.
Freeze drying changes the way you do preservation for long-term storage. Unlike other preservation techniques, freeze-drying allows you to maintain all the nutrients while preserving your food for long periods. It’s a better option than canning, as there are no alterations to the taste of your food. Now, freeze-drying isn’t just for food. It’s also a technique used in drying and curing cannabis. What takes weeks to months can be cut short to as few as 24 hours.
