In-line sensing in challenging manufacturing
environments is important for process analytics and control to enhance the
product quality, waste reduction, energy efficiency, and retrofit with
renewable energy and new technologies. In this talk, I will present a few
examples of my ongoing development of fiber optical sensors, from the
standpoint of an optical and mechanical engineer, in order to improve food
manufacturing process monitoring. Specifically, I will introduce fiber optical
sensors for real-time, in-line food moisture sensing, complex aroma
differentiation, and below-the-surface deformation measurements, respectively.
Different from commercially available electrical sensors, our fiber sensors are
small in footprint, easy to implement, compatible with harsh manufacturing
environmental conditions such as high temperatures (>200 oC) and
strong microwaves, and not susceptible to fiber bending or movement between the
product and the readout system. For each sensor, in-line measurements during
the food drying process either in a bench-top oven or in a pilot-machine will
be discussed, focusing on the expected user experiences if these sensors are
implemented in the industries.
