Abstract

Coffee is deprived of caffeine by disrupting the beans with steam, extracting them, and expelling the extracting agent by steam. The beans are treated with the steam in a perforated vessel surrounded by a jacket, so that the steam is prevented from condensing on the beans and depriving them of aromatic odour.
