Evaluation of a hand-operated coffee picker
The portable picking machine (described and illustrated) consists of 2 helicoidal spindles connected by gears that rotate the spindles in opposite directions. The spindles are placed on opposite sides of a fruiting branch and are pulled or pushed along the branch. Contact with the branch and berries causes the spindles to rotate. A basket surrounds the spindles in such a manner that harvested berries fall into it. The whole unit is held on a long handle for reaching the upper branches. In field tests with 5-years-old robusta trees the machine picked only 19.2 kg/h compared with 39.9 kg/h by hand-pickers, and it also damaged flowers and flower buds, picked green berries (29.2) and dropped a high percentage (31) of berries to the ground.
