drying techniques

Drying techniques encompass methods for removing moisture from materials, often to preserve them or alter their properties.

Freeze drying (lyophilization) uses sublimation under vacuum to retain structure and nutrients, while spray drying atomizes liquids into fine droplets for rapid dehydration.

Fluidized bed drying suspends particles in heated air for uniform drying, and zeolite drying employs porous minerals to adsorb moisture.

In archival processing, darkroom techniques like air drying or chemical baths prevent damage to photographic materials.

Freeze drying preserves strawberries by removing water while keeping their shape and flavor.
