Freeze Drying Methods - Complete Guide

Three major steps are used in the freeze drying process: freezing, sublimation, and desorption. In this section, we will guide you one by one.

Freezing

In this method, you can preserve the food items' original structure by freezing them at -40°F to -50°F.

Sublimation

It is the primary drying method in which dry fruits are put in the vacuum chamber. In the chamber, the pressure is lowered, and the fruit’s ice is turned directly into vapor rather than water. This is the most effective method for removing water from fruits.

Desorptions

It’s a secondary method in which the sublimated food items are gently heated to eliminate the remaining moisture or water molecules from freeze dried fruits. In the end, you will get dry, crunchy, and lightweight fruits with a long shelf life.
