Coffee Roast Machine
This study involved designing and producing the coffee roaster sized 480 1210 780 mm (W x L x H dimension). The roaster bucket is characterized of cylindrical and cone-shaped at the end lied horizontally with an adjustable stand. The cone is available for passing the coffee beans into the roaster bucket of 300 650 mm size (W x L dimension). The temperature measuring unit is used to check the heat level in the roaster bucket where 1/3 Hp motor humidity-sucking fan is installed. The 1/3 Hp fan and churching bucket are to suck the heat out of the coffee beans through cyclone separator. Regarding to heating, it relied on LPG as heater which gas knob is installed the roaster bucket which is rotating constantly while roasting to ensure the thoroughly roasting effectiveness of raw coffee beans. The capacity of the proposed coffee roaster can produce 5 kg roasted beans at a time, and approximately takes 30-35 minutes. The roasting temperature can be adjusted ranging 120 C - 300 C. Both Arabica and Robusta coffee beans can be roasted by using this device.
