How does industrial freeze drying work?
The principle of industrial freeze-drying involves freezing the material first, then removing the moisture by turning the ice directly into water vapor in a vacuum. This process has three main steps:
1.Freezing: Cool the material below its freezing point to turn the moisture into ice.
2.Sublimation: In a vacuum, the ice turns directly into water vapor and leaves the material.
3.Drying: Remove any remaining moisture by raising the temperature slightly.
How long does industrial freeze dryer take?
The time it takes for an industrial freeze dryer to complete a cycle depends on several factors, including the type of material, its volume, moisture content, and the specific freeze-drying process used. Typically, the entire process can range from a few hours to several days. Smaller batches with lower moisture content generally finish faster, while larger volumes or higher moisture levels might require more time.
