The non-uniformity of coffee fruit maturation is an intrinsic plant condition that is not favorable for the beverage quality. This could be overcome by using the precision harvesting approach, wherein only the ripe fruits are harvested. The objective of this work is to evaluate a methodology for selective coffee harvesting, including optimal harvester settings in each management zone. The management zones were determined according to productivity and maturity of coffee fruits. Selective harvest (with two harvester passes) is compared with one time total harvest. At the first harvest the following settings were tested: R1 = 800 and 500, R2 = 700 and 700, R3 = 1000 and 500, and R4 = 900 and 700 (m h−1 and rpm, respectively for speed and vibration). In second step, July 2018, the settings were R1 = 900 and 950, R2 = 700 and 950, R3 = 800 and 800, and R4 = 1000 and 800. It was concluded that it was not possible to harvest only the riped fruits with any setting regardless of management zone. The tested settings do not change the amount of fruits harvested, the regulation with higher operational speed is recommended for economic reasons. Harvesting the upper third of the coffee tree first yielded better beverage quality and less sweeping coffee, but did not cover the operating costs.

在产量和成熟管理区选择性收获咖啡的方法

咖啡果实成熟的不均匀性是不利于饮料质量的内在植物条件。这可以通过使用精确收获方法来克服,其中只收获成熟的果实。这项工作的目的是评估选择性咖啡收获的方法,包括每个管理区域的最佳收获机设置。管理区根据咖啡果实的生产力和成熟度确定。选择性收获(两次收获机通过)与一次总收获进行比较。在第一次收获时,测试了以下设置:R1 = 800 和 500,R2 = 700 和 700,R3 = 1000 和 500,以及 R4 = 900 和 700(速度和振动分别为 mh-1 和 rpm)。第二步,2018 年 7 月,设置为 R1 = 900 和 950,R2 = 700 和 950,R3 = 800 和 800,和 R4 = 1000 和 800。得出的结论是,无论管理区域如何,都不可能在任何环境下只收获成熟的果实。测试设置不会改变收获的水果数量,出于经济原因,建议使用更高的运行速度。首先收获咖啡树的上三分之一,可以生产出更好的饮料质量和更少的咖啡,但没有支付运营成本。
