Abstract
The aim of this study was to evaluate the effects of the six different manual coffee grinder combinations with two handle lengths (short pole: 8 cm, long pole: 13 cm) and 3 holding angles (0°, 45°, 90°) on grinding bean performances. A better combination of handle length and holding angle was deter-mined by complete time and subjective responses. The results showed that when the user is grinding coffee beans, the manual coffee grinder with a long pole handle was more efficient than a short pole. No significant difference in complete-time was found in holding angles and the interaction of handle length and holding angle. For the subjective responses, the combination of a long pole with a holding angle in 0° was a better satisfactory combination. The findings of the research provided valuable information for the designs of manual coffee grinders.
