Process engineers continue to refine old as well as develop new applications for heat.
Retort is synonymous with thermal processing, and it illustrates thermal’s constant evolution and change. Since the saturated steam retorts of the early 20th century, systems have evolved to full emersion, steam air with fan agitation and, finally, the steam water sprays that surfaced a decade ago. Systems are constantly being modified to meet different industry demands, whether it’s greater energy efficiency, new packaging types or foods with better taste and appearance.
