“…A similar technological initiative has already been experienced in Vilcabamba, Ecuador, allowing comparisons of the efficiency and time of grain drying [ 118 ]. Vilcabamba is located 1700 m.a.s.l., with 4778 inhabitants; of these, 39.9% are between 30 and 64 years old, with a poverty level of 61.8%, and an illiteracy level of 5.09% [ 119 , 120 ].…”

The coffee plant, with more than 40 billion shrubs, 9 million tons of grains produced, and 80% of its production accounted for by small-scale producers, has been severely damaged since the emergence of Hemileia vastatrix and Hypothenemus hampei. Despite technological support, these pests have caused 20% to 40% production losses, a 50% to 60% deficit in performance, and a cost of between USD 70 million and USD 220 million to the world economies, which forces us to rethink actions centered on people as the key elements to develop appropriate solutions. For this, the present study presents a technological proposal centered on small indigenous coffee producer requirements for introducing Industry 5.0 technologies, considering roadmapping, knowledge management, statistical analysis, and the social, productive, and digital contexts of five localities in Mexico. The results show a correlation between monitoring and control, soil analysis, the creation of organic fertilizers, accompaniment, and coffee experimentation, as the actions to be implemented, proposing the introduction of a mobile application; sensors, virtual platforms, dome-shaped greenhouses, and spectrophotometric technology as relevant technologies centered on indigenous coffee producers’ requirements. This study is important for policymakers, academics, and producers who wish to develop strategies centered on people in Mexico and the world.

“…Although coffee (Coffea arabica L.), due to commodities such as oil, gold, and other minerals, has gone from occupying 60.0% of exports during the 1970s to only 5.0% in the current decade, it remains the historically most traded tropical product in Latin America (Pineda et al, 2019). Its consumption and economic relevance is undeniable and constitutes an important livelihood for millions (Briceño-Martínez et al, 2020), so much so that European countries encourage alternative systems of production and trade that are environmentally sustainable and equitable in the distribution of the profits it generates (Estevez et al, 2018).…”

The production of specialty coffees is the main objective of coffee growers worldwide and depends on the selection of optimal grains; however, especially in Latin America, they are processed manually and are influenced by subjectivity. The objective of the article was to verify the effectiveness of a cherry coffee sorting prototype with image recognition using machine learning in real time compared to the traditional method in the Valle Grande Association, Peru. Covolutional neural network processing was used. 24,000 images labeled in the Labellmg program of green, ripe, pinton, over-ripe and dry Catimor grains were trained with the YOLOv3 algorithm. The results describe the mechanical-electronic design and assembly procedure of the prototype with the necessary technical specifications for its replication; In addition, they demonstrate their effectiveness in reducing the selection time by approximately 3 hours, with a precision level of 94.0% in four samples of 100 kg of coffee. It is concluded that the prototype is a potential alternative, reducing cost, saving time and providing a useful tool to guarantee the selection of grains that allow obtaining quality higher than 83 SCAA points.

Reducing the drying time of coffee without causing negative effects on cup quality has been the subject of several investigations. The objective was to determine the effect of three variants of a greenhouse-type solar dryer prototype on the physical, sensory and microbiological quality of coffee. The solar dryer prototype with three variants, prototype 1 (P1) greenhouse solar dryer, prototype 2 (P2) solar dryer with air extractor and prototype 3 (P3) solar dryer with air extractor and solar powered heaters, was compared to traditional drying (T0) (cement floor). Drying time, physical grain defects, yield, sensory and microbiological quality were evaluated. The best results were obtained in P3 with a drying time of 52 h (2 ¼ days), with dry parchment coffee beans without primary defects, higher yield in exportable gold coffee (83.24 %), sensory profile of 84.25 points qualified as specialty coffee (with Q Premium grade) and better safety than coffee obtained by traditional drying; demonstrating that the greenhouse type solar dryer with air extractor and solar energy heaters is a sustainable alternative to improve the efficiency of coffee drying while preserving its sensory quality, an essential value for producers to achieve better prices.
