Desarrollo de una herramienta manual para asistir la recolección de café en Colombia
Coffee harvest as carried out in Colombia, hand picking only mature fruits one by one, permit to obtain the highest quality, world-wide-known coffee. Nevertheless, by using this harvesting technique the manual labor yield is notoriously reduced. In this study the first step in manual tools development was initiated to increase the operating yield by simultaneously detaching and collecting several fruits, aminly mature. In the design of the equipment called ORSEL ("ORdeñador SELectivo"), morphologic, physical and mechanical properties of coffee clusters, Colombia variety, were considered. For the conception of the tool the CESAM method, proposed by Marouzé and Giroux (1998) for the design of agricultural equipment in less developed countries was applied. The tool was evaluated and compared to the traditional method (hand picking) under field conditions, using a commutative experimental design. The results obtained showed an important increment in the operative yield (more than 80 percent in relation to the traditional hand picking method), efficacy (detachment of mature cherries) higher than 50 percent; the harvesting quality was not acceptable for the Colombia standards (19 percent green fruits in the harvested mass).

| Summary: | Coffee harvest as carried out in Colombia, hand picking only mature fruits one by one, permit to obtain the highest quality, world-wide-known coffee.

In this study the first step in manual tools development was initiated to increase the operating yield by simultaneously detaching and collecting several fruits, aminly mature. In the design of the equipment called ORSEL ("ORdeñador SELectivo"), morphologic, physical and mechanical properties of coffee clusters, Colombia variety, were considered.
