Estudio del secado de Physalis peruviana Linnaeus por ventana de refractancia y comparación con secado convectivo y convectivo asistido con radiación infrarroja
(Universidad de Chile, 2022)
de energía térmica (EUter: 5,982×1006 - 8,658×1006 kJ) y tiene una eficiencia energética menor (ηe: 28,7 a 37,9%).
En cuando al efecto del proceso en el color, con todos los secados se produjo un cambio de color desde amarillo intenso con un tono...
The Refractance Window drying process is an emerging technology that stands out for the use of a plastic film and water as the source of the caloric energy to achieve the evaporation of moisture, a study of this technology to dry Physalis fruit, a fruit that is rarely used in industrialized process, allows to expand the knowledge in Refractance Window and Physalis for new ways for its consumption. For this study, Physalis puree was dried by Refractance Window (RW) (in laboratory and industrial scale equipment) at 50, 60 and 70 °C, and in addition drying was carried out by convective air and by convective air aisited with infrared light of 250, 500 and 1000 Watts, at temperatures of 50, 60 and 70 °C. the results obtained of the drying by RW, display a characteristic drying kinetics of conventional drying processes, an inverse relationship between temperature and time, a diffusivity of high values (Deff: 5,447x10-8 to 9,718x10-8 m2s-1), a characteristic Ea value (45,267 kJ / mol), it was found that the Weibull model is the most appropriate for teh mathematical adjustment. Regarding efficiency, RW is the drying that needs the most energy to heat the material (Qw: 4,604x1008 and 4,647x1008 kJ), it presents the highest thermal energy consumption (EUter: 5,982 × 1006 - 8,658 × 1006 kJ) and has the lowest energy efficiency (ηe: 28.7 to 37.9%). Regarding the effect of the process on the color, with all the dryings process there was a color change from intense reddish yellow with high luminosity to an reddish orange color, with less saturation and luminosity. The Refractance Window drying process is an option to the conventional drying methods that achieves a product with low moisture content and features that allows expanding the ways of consumption of food products and gives the possibility of creating new ingredients...

Local governments play a key role in climate action at a local level, even when it is not mandatory in Chile, and when they often do not have the necessary tools and resources to accomplish this task. It is here where cooperation alliances arise that allow the execution of this role in a better way. In this context, this study had as main objective to evaluate the cooperative experience to integrate climate action, led by Adapt Chile, for the municipalities of the Chilean Network of Municipalities for Climate Action (RedMuniCC) during 2014 and 2015. To do this, each actor involved (Adapt Chile, RedMuniCC and 10 municipalities) were characterized, giving a context of their position in society, the main laws that determined them and the climate action that they have implemented updated to date under study. The evaluation was made adapting the methodology proposed by SECIPI (2001 & 2007) and Monsangini (2012) to evaluate the decentralized cooperation, which in this case is a mid-term and voluntary evaluation, that consisted in 8 indicators that allowed to qualify relevance, effectiveness, efficiency, impact, and the sustainability of the design and implementation of the program. Finally, recommendations were made for the improvement of the program and its subsequent reevaluation. The characterization of actors showed both multiple realities and similarities that municipalities face and that determined the type of climate actions they implement, where initiatives associated with water, energy and waste management, and environmental education, predominated. The evaluation required an extensive review of documents and records in order to build baselines that would allow the application of the indicators, which has the following qualification: very high level of municipal interests consideration; high level of municipal reality and capacities consideration; medium level on the adjustment with regional and national public policies; high level of goals achievement; medium efficiency on the use of resources; high positive impact for municipalities; very low positive impact for local communities; and a medium level on the consideration of the continuity of climate action in municipalities. These outcomes turned into a high level of pertinence and effectiveness of the program, and a medium level in its efficiency, impact and sustainability. The main recommendations aim to create a road map for every two years, in order to focus cooperation’s efforts and resources, to ground intervention’s goals and objectives, and to improve future monitoring and re-evaluation. Finally, it is worth noting the importance of initiatives such as RedMuniCC and its common work with a civil society institution in order to implement and achieve climate action goals, as well as the need to improve the monitoring, report and evaluation mechanisms to assure the continuity of local climate action....
