Drying is considered one of the industrial processes that requires more energy than other processes, being a topic of much interest to the agricultural sector, especially the evaluation of energy consumption for rice and corn dryers. To meet this goal, an overview survey matrix and protocols for temperature measurements of dryers were developed. The study evaluated 49 rice dryers and 14 yellow corn dryers. As a result, it was determined that the oversizing of the fan/extractor and the dryer engine generates a high energy consumption, added to the lack of insulation in the heat ducts. Therefore, the drying productivity index is very low in dryers using liquefied petroleum gas (LPG) being 0.14 dollar/quintal for rice and 0.27 dollar/quintal for corn and using biomass reaches 1.4 dollars/quintal. In relation to energy losses, these account for more than 55%. Inadequate energy management in drying processes directly influences the marketing chain of products, the losses of which are caused by fluctuations in the price of rice and corn on the domestic market, with the agricultural sector having to generate an energy efficiency plan.
The Galapagos Islands is one of the world's pristine archipelago. It has been inscribed as an UNESCO World Natural Heritage since 1978 [1]. This archipelago is also well known because Charles Darwin studied the origin of species in these islands. However, it is in great threat due to the main energy source is diesel. Hence, the Ecuadorian government has an initiative called 'Zero fossil fuel in the Galapagos Islands' which aims to reduce diesel consumption by replacing it for renewable energy. In this context this research will show the electricity sector market mix particularly of Santa Cruz island, in order to indicate how much is done and needs to be done to become an island fossil fuel free in electricity generation. It will present a literature review as well as novel information from electricity generated in 2014 by the solar PV power plant of Santa Cruz and a forecasted wind generation of 2014 of Santa Cruz base on wind speeds from a meteorological tower. It concludes that even though the significant efforts of international cooperation to co fund renewable energy projects in order to increase its installed capacity, almost 80% of the electricity is generated by thermoelectric turbines run by diesel.
