Abstract

Appts. comprises a feed hopper in which the coffee flows down successive inclined surfaces into a pre-heating hopper; this heats the coffee to 140 degrees C. A spreading device distributes the heated coffee on a conveyor belt which is provided with a stirring assembly. The belt passes under two rows of infra-red elements, the spacing of which can be adjusted by means of a hand-wheel. The coffee is then cooled, humidified and packed in vacuo. The prod. is superior in quality to that roasted by a conventional method and it has better storage properties. The colour of the grains is more uniform and the colour inside the grain is much closer to the surface colour. The aroma is improved, partic. in the case of a low quality coffee. Wave-length of the IR is pref.
