Freeze Drying / Lyophilization Information: Basic Principles

Sublimation in the freeze drying process can be described simply as: FREEZE - The product is completely frozen, usually in a vial, flask or tray. VACUUM - The product is then placed under a deep vacuum, well below the triple point of water. DRY – Heat energy is then added to the product causing the ice to sublime.

Introduction to freeze drying - Labconco

There are three stages in the lyophilization process: Pre-freezing, primary drying, and secondary drying. Pre-freezing. The pre-freezing stage is the most important stage of the freeze-drying process.

Freeze Dryers and Hash: Vacuum Drying vs. Freeze Drying

Like freeze drying, vacuum drying is a three-step process that includes a freezing phase followed by a sublimation step and then a secondary drying phase. Virtually all Harvest Right freeze dryers dry via vacuum drying, not freeze drying. Consider This… Dry hash production is a process that is still very much being figured out.
