Freeze Drying / Lyophilization Information: Basic Principles

Primary drying is a top-down process with a well-defined sublimation front moving through the product as it dries Above the ice surface interface is dried product or "cake" below the interface is product with ice crystals still remaining to be sublimed At the end of primary drying when all of the free ice crystals have been sublimed the product will appear to be dried However the

Drying

12/12/2014Drying occurs in three different phases INITIAL PERIOD Sensible heat is transferred to the feed that contained moisture Heating up the feed from the inlet condition to the process condition The rate of evaporation increases dramatically during this period with mostly free moisture being removed Pre-processing can reduce or eliminate this phase e g preheated by a source of waste energy

Pulse Combustion Spray Dryer Technical Details

When the nozzles or rotary disks of a conventional spray dryer begin to wear the dynamics of atomization change and the dryer begins to produce a different particle In a pulse dryer there are no atomizer parts to wear out every droplet sees the same atomization energy and the same differential temperature Thus particle size distributions tend to be tighter than those obtained from a
