5. Theory  Lyophilization is carried out working with an easy basic principle of physics sublimation. Sublimation could be the changeover of a substance in the good into the vapour state, without having very first passing by way of an intermediate liquid period.  Lyophilization is carried out at temperature and pressure situations below the triple issue, to enable sublimation of ice.

This assessment attains to disassemble FD complications as a result of a detailed rationalization on the lyophilization thought, phases, the things influencing the process which include managed ice nucleation, plus the modified and revolutionary FD systems proposed recently to overcome the scarcity of classic FD.
