Freeze drying, or lyophilization, is a process that removes moisture from various materials, preserving them for extended periods.
This technique involves freezing the material and then reducing the surrounding pressure to allow the frozen water to sublimate directly from the solid phase to the gas phase.
Freeze drying is now widely used across multiple industries. Laboratories utilize it for preserving specimens and reagents, while commercial production employs it for making shelf-stable food products, preserving flowers, and processing cannabis. Additionally, taxidermists use freeze-drying to preserve animals for display.
The freeze-dryer market has expanded with a variety of brands, each offering unique features. While this abundance of options provides more choices, it can also lead to decision paralysis, making it difficult to determine the best freeze dryer for your needs.
To assist you in making an informed decision, we’ve compiled a detailed overview of popular freeze-dryer brands available today, highlighting their key features and innovations.
