Design of an effective heat exchanger for cinnamon oil extraction

Abstract

Lack of knowledge in heat exchanger design and fabrication is the major hindrance for improving the cinnamon oil extraction process in Sri Lanka. Most of the extraction plants use submerged coils in still water where the temperature approach is not sufficient enough to have efficient heat transfer resulting in using of large heat transfer areas unnecessarily. Further due to poor heat transfer efficiencies, most of the highly volatile compounds in the essential oils escape to atmosphere without been condensed.
