If the humidity is faraway from the structures, they stabilize considerably, permitting the medication for being stored for an extended period and reconstituted later by incorporating humidity once more.
Freeze drying’s 2nd stage is Main drying (sublimation), wherein the pressure is reduced and heat is extra to the material in order for the drinking water to sublimate. The vacuum speeds sublimation. The cold condenser presents a surface area for that h2o vapor to adhere and solidify.
