Especially for large batch
productions, the utilization of automated systems that work
at higher operation speeds is favorable. A high number of
droplets can be prepared within a short time by ejecting
cellulose solutions through a rotating cylindrical vessel with
small outlets (spinning drop atomization, Figure 2c).24.26
Adjusting the rotational speed, geometrical parameters of the
cup, and size of its outlets allows particle sizes to be controlled
efficiently.27,28 As a result of the high forces applied to the
cellulose solution, it is also possible to obtain droplets of
comparably small diameters of 500 ìm or less. Another
potential technique for droplet formation is “spinning disc
atomization” (Figure 2d). Here, a thin film of the polymer
solution is constantly spread onto a rotating disc and droplets
are ejected from the edge as a result of centrifugal forces.29,30
