概要 |
Cacao has a significant impact on the food industry. Approximately 6.5 million tons of cacao are produced every year. The study aims to design and fabricate a combined cacao bean huller-pulverizer whe...re roasted cacao beans are processed to cacao powder. The machine was tested in terms of its capacity, efficiency, and fineness modulus. The result showed that the combined cacao bean huller-pulverizer has an average output capacity of 4.74 kg/hr and an average output efficiency of 46.8%. The cacao powder produced by the machine has a fineness modulus of 3.62. In contrast, the fineness modulus of the commercially available cacao powder was 4.33. The two different cacao powders showed a significant difference using an independent sample t-test. Based on the results, the overall performance of the combined cacao bean huller-pulverizer was fair. The financial feasibility of the machine was also evaluated, and a positive economic impact was observed.続きを見る
