The working principle of a freeze dryer, or lyophilizer, revolves around the process of freeze-drying, which consists of three main stages: freezing, primary drying (sublimation), and secondary drying (desorption). Here’s a detailed explanation of each stage:
1. Freezing:
Process: The product is rapidly frozen at temperatures typically around -40°C (-40°F) or lower. This transforms the moisture content in the product into ice.
Purpose: Rapid freezing minimizes the formation of large ice crystals, which helps preserve the structure and integrity of the product.
2. Primary Drying (Sublimation):
Process: The chamber pressure is lowered (creating a vacuum), and heat is applied. The ice in the frozen product sublimates, meaning it changes directly from a solid (ice) to a gas (water vapor) without passing through the liquid phase.
Purpose: This stage removes approximately 95% of the moisture content while maintaining the product's shape and nutritional quality. The low pressure allows sublimation to occur efficiently.
