Abstract: VIDALLO, ARCIELI ARCENA. Don Severino Agricultural College, Indang, Cavite, April 1994. "DESIGN, CONSTRUCTION, AND TESTING OF AN INCLINED DRUM COFFEE ROASTER". Adviser: Engr. Jaime Q. Dilidili A motorized coffee roasting machine was designed, constructed, and tested at the School of Engineering to find the machine performance in terms of roasting time and fuel efficiency. The machine was tested using different types of fuels to obtain better heating results. Coffee pulp, coconut shell charcoal and wood charcoal were used in the study. The roaster consisted of an inclined roasting chamber, a housing chamber and claypot heating burner. The roaster was evaluated using coffee beans while treatment used were coconut shell charcoal, coffee pulp and wood charcoal. Results showed that the kind of fuel materials used in roasting significantly affect roasting time, consumption, weight of roasted beans and temperature of the fuel roasting chamber. The best result was obtained using coconut shell charcoal as fuel having the highest roasting temperature 143°C, shortest roasting time of 7.44 hours and smallest quantity of fuel consumed of 12.6 kgs. The machine has an initial investment cost of #4403.00. It has an annual gross revenue of P43200.00 and net income of #3487.94. Payback period, break-even point, and benefit cost ratio the roaster was computed to be 1.26 years, 789.40 hours per year and 1.10, respectively.
