ABSTRACT:
Coffee roaster, preferably having no moving parts and suitable for domestic use, in which a current of hot air is caused to pass through a layer of coffee beans supported on a perforated plate or belt, the space above the beans being enclosed by sidewalls and a top cover having one or more openings for outflow of air. The top cover causes heat to be radiated back onto the beans and the flow of hot air causes water vapor and other gases resulting from roasting, also smoke, to be rapidly removed from the beans and vented. In a variant the roaster may be enclosed in an oven and the cover of the oven may be imperforate, the oven being provided with means to vent air, water vapor and other gases.
