Abstract

The roasted beans are fed from a hopper via a regulator valve to the injector pipe with at its outer end a pressurised gas nozzle and its inner end discharging tangentially into the upper part of an inner, vertical, perforated cylinder contained within a solid walled outer shell into whose annular gap the burnt husks of the beans are expelled through the perforations, by a combination of centrifugal force and gas pressure. Separate drain pipes with shutter valves for the dust and for the beans are connected to the conical bases of the outer shell and the inner perforated cylinder respectively. The gas is recycled from the top of the outer chamber by a pump via a mixing/cooling valve into which a top-up supply of liquefied gas is fed through a regulator. Both the main coolant gas and the top-up liquefied gas are N2.
