Abstract

This study evaluated the performance of a novel rice puffing machine equipped with an LPG heating system, using IR-64 rice variety. Optimization of puffing temperature (210°C) and heating cylinder speed (35 rpm) yielded maximum puffing capacity (45 kg/hr), puffing efficiency (89.30%), and expansion ratio (346.00%). Economic analysis revealed a cost of production of Rs. 41.50 per kg of puffed rice, with a benefit-cost ratio of 1.45:1. The results demonstrate the machine's potential for small-scale entrepreneurs and start-up businesses in the puffed rice industry, offering improved efficiency, hygiene, and profitability.
