freeze dryer

Vacuum preservation machine

A freeze dryer is a machine that preserves food or other materials by freezing them and then removing moisture through sublimation—turning ice directly to vapor under vacuum.

The process retains flavor, nutrients, and structure better than conventional drying: The lab uses a freeze dryer for tissue samples.

Home freeze dryers have become popular among preppers and backpackers.
