Abstract

This study describes performance of four separators (Strich's model A, Atienza type I model B, Atienza type II model C and Quin Mattel type model D) to separate coffee beans from coffee harvested by nets on private plantations in Adjuntas, Puerto Rico. Collection unit yielded a bean content (wet basis) of 79.7, 92.8, 79.4 and 73.7 percent for models A, B, C, D, respectively. It gave a trash content (wet basis) of 7.2% for model B, 20.3% for model A, 20.6% for model C and 26.3% for model D compared to a bean loss of 0.9% in model D, 1.8% in model C. Machine output was 73.8 kg/hr for model A compared to 179.8 for model C, 724.9 for model B and 1673.5 for model D. The machine output-input ratio (wet basis) was 0.60, 0.57, 0.68 and 0.61 for models A, B, C and D, respectively.
