Abstract

Nigeria local method of maize roasting is prone to high operating stress, uneven roasted maize, high greenhouse effect, low hygienic level and higher time per roast operation, this study was therefore design to explore modern method that can drastically reduce these challenges. From among alternatives considered a 2.976 kg roasted maize in fifteen minutes roasting machine was designed, fabricated using economically available local resources and evaluated. The machine consists majorly electric motor (2.5 rev/min to 3 rev/min) mounted on bearings, selected heating elements (2.07kW calculated based literature standard), transmission and drum shafts, perforated galvanized roasting drum and thermostat (200oC maximum temperature). The machine was tested empty at full chamber volume that took average of 51 minutes and 36 second to reach 200oC from ambient temperature. Other tests carried out helped to establish, the optimum roasting mass for the machine was 2 kg compared to design capacity value of 2.976 kg roasted maize in fifteen minutes. The roasting process was carried out faster with lesser stress, zero greenhouse gasses in a hygienic environment as calculated for.
