Abstract
A process control system has been constructed using optical fibres interfaced to a Fourier Transform Infrared (FT-IR) spectrometer, to achieve remote spectroscopic analysis of food samples during processing. The multi-channel interface accommodates six fibres, allowing the sequential observation of up to six samples. Novel fibre-optic sampling cells have been constructed, including transmission and attenuated total reflectance (ATR) designs. Different fibre types have been evaluated, in particular plastic clad silica (PCS) and zirconium fluoride fibres. Processes investigated have included the dilution of fruit juice concentrate, and the addition of alcohol to fruit syrup. Suitable algorithms have been written which use the results of spectroscopic measurements to control and monitor the course of each process, by actuating devices such as valves and switches.
