Most of these coffee cherries are ripe, but some are still green. Selective Harvesting. These fish plates fill the gaps between the tree trunks, and because of their angle the coffee cherries are rolled to the internal horizontal conveyers, which lead to other conveyers and finally to the holding bin. Attached to the columns are hundreds of picking rods, which vibrate and oscillate as the weights on top rotate. Yet we must consider if these are well paid and whether they offer a good quality of life. The vibration of these rods through the trees is what picks the coffee off the tree. However, 'Conilon' and arabica coffee plants differ for their morphological and physiological The adoption of a fully-mechanised system thus requires careful planning from row spacing through to field extraction roads and routes. It could also result in lower crop yields if under-ripe coffee cherries are discarded post-harvesting. And that means only coffee beans from the ripest of cherries should make it into the final product. Ricardo Pereira also tells me, “[With mechanical harvesting], you can adjust the rates of vibration and speed of the arms in the machine to ensure you just collect the ripest cherries.”. TN6 2JD
