FIGURE 5.88 Schematic of a co-extrusion process of microencapsulation being developed at Southwest Research Institute (SWRI) using machine vision-based control system that allows inflight capsule inspection. The desired capsule size and sphericity are obtained by manipulation of process input variables, such as flow rate, temperature, vibrational frequency, and amplitude via a feedback control loop.

Institute (San Antonio, Texas) allows inflight capsule inspection, while the process input variables including flow rate, temperature, vibrational frequency and amplitude are manipulated via a feedback control loop to obtain desired capsule size and sphericity [207]. Due to the involvement of so many factors and their complex interrelationships, co-extrusion processes are designed and operating conditions determined usually on a case-by-case basis.
