J., Ruiz-Blanco, J. R., y Ayala-Covarrubias, E. G. (2022). Energyno (Version 1). [programa de cómputo]. El Colegio de la Frontera Sur.). Los sensores fueron colocados en el interior y exterior de ciento quince viviendas, todas de techo de lámina, que es el material más utilizado en la región de la Chontalpa Tabasco. Los datos registrados fueron acumulados en la base de datos que se comparte en este repositorio Matter: Temperatura Sun, 01 Jan 2023 00:00:00 GMT https://repositorio-energia.conahcyt.mx/jspui/handle/1000/342 2023-01-01T00:00:00Z https://repositorio-energia.conahcyt.mx/jspui/handle/1000/340 Title : Solar Technology in Agribusiness: Impact and Results of the Solar Drying Plant in Zacatecas Authors: NESTOR MANUEL ORTIZ RODRIGUEZ Summary or description: In response to global challenges in agribusiness, this work presents the results of the strengthening of the Solar Drying Plant for Agricultural Products in Zacatecas, Mexico. The plant has implemented solar energy technologies combined with biomass and LP gas backup systems, as well as a heat pump dryer. These advancements have increased the plant’s capacity by 300%, enabling the recovery and valorization of over 232 tons of fresh agricultural products between 2022 and 2024, such as garlic, prickly pear, and apples. Additionally, the project has promoted regional development through the creation and strengthening of 16 businesses and enterprises, generating employment and enhancing the agribusiness value chain. More than 50 training and outreach events have been held, along with the formation of over 20 professionals specialized in solar drying. Environmentally, the plant avoided the emission of 58.217 tons of CO₂ by replacing fossil fuel-based energy with solar energy. The experience gained in Zacatecas demonstrates that solar technology is an effective solution to promote sustainability in agribusiness and the energy transition, integrating technological, economic, social, and environmental impacts. This model is replicable in other regions seeking sustainable solutions for food preservation.

Two experiments were conducted. Experiment I varied the LP (liquefied petroleum) gas supply pressure (LPGSP) from 70 to 110 mbar at a 38.0 cm-fixed distance between the emitter and the CPCS. Experiment II varied the distance between CPCS and CIR-emitter at 50 mbar of LPGSP. The Page's model showed the best fit (R²=0.99) to describe the drying kinetics. In Experiment I, 80 mbar gas supply pressure and 70 min of drying (2615.51 ± 9.65 W/m²) was the best condition, with higher non-digestible carbohydrates content. Meanwhile, scavenging of ABTS and DPPH were higher at 100 or 110 mbar. In Experiment II, the best distance between CPCS and CIR-emitter was set at 14.0 cm, however, phytochemical losses were observed. Non-digestible carbohydrates, condensed tannins (5.7 mg CAE/g), and saponins (5.0 µg OAE/g) were higher at 24.0 cm, while carotenoids where enhanced at 38.0 cm. Furthermore, 14.0 and 38.0 cm had the highest DPPH and α-amylase, and ABTS and pancreatic lipase inhibition, respectively. The exploratory results establish a foundation for optimization of CIR technology in drying processes, as a promising alternative to reduce drying time while maintaining functional properties, which are essential for human health. Future perspectives include scaling up CIR technology for industrial applications, as it offers significant opportunities to enhance energy efficiency, reduce post-harvest waste, and contribute to food security and sustainability in the agri-food sector.

Expone la problemática del desperdicio alimentario en productos frutihortícolas, agravada por la falta de infraestructura de conservación, interrupciones en la cadena de frío y limitada transformación agroindustrial. Se describen distintas tecnologías de secado solar: directas, indirectas e híbridas, evaluando sus principios de funcionamiento, componentes clave (colector solar, cámara de secado, sistema de ventilación), y ventajas frente a métodos convencionales. El secado indirecto se resalta por ofrecer mayor inocuidad y control de calidad al evitar el contacto directo con la radiación y contaminantes. Se discuten aspectos técnicos fundamentales como el diseño térmico, selección de materiales, comportamiento higrotérmico, eficiencia energética, y la posibilidad de incorporar automatización y control mediante sensores y ventiladores forzados. También se abordan criterios de inocuidad, tiempos de secado, conservación de compuestos bioactivos y parámetros críticos para el desarrollo de productos estables, seguros y de calidad. El texto enfatiza la importancia de adaptar los sistemas a condiciones climáticas locales y a productos específicos (ej. nopal, durazno, tomate, entre otros). Se promueve la integración de energías renovables, tecnologías de bajo costo y participación comunitaria como ejes de una estrategia sostenible y replicable. Finalmente, se destacan experiencias piloto e iniciativas de innovación abierta como bases para escalar el secado solar en cadenas agroalimentarias locales, reduciendo pérdidas poscosecha, generando valor agregado y fortaleciendo la seguridad alimentaria.
