PERFORMANCE EVALUATION OF ROTATING CYLINDER TYPE COFFEE BEAN ROASTER
Abstract: One strategy
attempts to reduce dependence on primary commodity markets are overseas market
expansion and development of secondary products. In the secondary product
processing coffee beans is required of supporting equipment to facilitate these
efforts. Research Center for Indonesian Coffee and Cocoa has developed coffee
bean roaster. However, there are still many people who do not know about the
technical aspects of roaster machine type of rotating cylinder so that more
people use traditional ways to roast coffee beans. In order for the benefits of
this machine is better known society it is necessary to study on the technical
aspects. The purpose of this research is to evaluate the technical performance
of the coffee beans roaster machine type of rotating cylinder. These include the
technical aspects of work capacity of the machine, roasting technical
efficiency, fuel requirements, and power requirements of using roaster machine.
Research methods are including data collection, calculation and analysis. The
results showed that the roaster machine type of a rotating cylinder has
capacity of 12.3 kg/hour. Roasting efficiency is 80%. Fuel consumption is 0.6
kg. The calculated amount of the used power of current measurement is the
average of 0.616 kW.
