Maize is a coarse grain and accepted as staple diet and its demand is increasing year by year. The maize production of India in 2011-2012 is 21.5 million tones and the area under production is 7.18 million hectares and yield is 1959 kg/hectares. Research work is carried out on performance of hot air puffing system for corn. The continuous hot air puffing system can be set to any puffing temperature from 180 to 270°C and air velocity of 20 to 30 m/s. The performance of the developed machine was evaluated at different puffing temperatures (200°C, 220°C, 240°C and 260°C) and at different feed rate (50 g/min and 100 g/min). The optimum conditions for puffing of popped corn were found to be puffing temperature of 200°C and feed rate of 100 g/min. The puffing percentage and expansion ratio of popped corn were observed to reduce with increase in puffing temperature and feed rate the maximum puffing percentage and expansion ratio were found at 200°C as 86.51% and 13.36.
