dc.description.abstractIn India, the street vendors practiced the traditional method for roasting or boiling the sweet corn. As these roasted or boiled corns are among the most popular snacks enjoyed by the people. The unavailability of an integrated corn roasting cum boiling unit is mainly due to the huge gap between the affordability of Indian street vendors and the high cost of the machines for roasting and boiling. Apart from this, the Indian vendors also experience another drawback in the form of drudgery involved during roasting and boiling where they are constantly exposed to heat. In the traditional practices, the uneven roasting of corns effects its outer beauty or attractiveness, which are disliked by the people. The use of power driven and automated equipments are impossible for Indian street vendors due to their economic conditions. Therefore, developing of a corn roasting device with increased efficiency, productivity and with affordable price is very much needed in order to face the stress and limitations during roasting. In the view of this, a gas fired portable maize roaster-cum-boiler was designed and developed and its performance evaluation was evaluated. The developed roaster-cum-boiler can roast around 30 maize and can boil around 28 maize in an hour. The average heat utilization factor in full load condition was 0.254. An average thermal efficiency of 61.88% was obtained for the unit. The mean roasting efficiency of the developed corn cob roaster cum boiler was determined to be 95.07 per cent. Total cost of the functional prototype is Rs 20,735. The net present worth calculated for next 5 years was Rs 2,10,881, internal rate of return 294.30%, benefit cost ratio 1.37 and payback period 0.33 years inferring that the developed unit is economically viable.
