“…Several countries have started to concentrate efforts to expand the use of solar energy in various sectors to reduce the use of fossil fuels (Chen et al, 2019;Pelda et al, 2020;Lipińskia et al, 2021). In the agricultural sector, solar energy makes it possible to perform drying with a dryer that has low costs of installation and maintenance, in a clean way, with no risk of contaminating the environment and agricultural products (Kumar & Singh, 2020;Paes et al, 2020;Nukulwar & Tungikar, 2020).…”

Increasing the efficiency of solar dryers with ensuring that the system remains accessible to all users can be achieved with their automation through low-cost and easy-to-use technique sensors. The objective was to develop, implement and evaluate an automatic system for monitoring drying parameters in a hybrid solar-electric dryer (HSED). Initially, an automated data acquisition system for collecting the parameters of sample mass, air temperature, and relative air humidity was developed and installed. The automatic mass data acquisition system was calibrated in the hybrid solar-electric dryer. The automated system was validated by comparing it with conventional devices for measuring the parameters under study. The data obtained were subjected to analysis of variance, Tukey test and linear regression at p ≤ 0.05. The system to turn on/off the exhaust worked efficiently, helping to reduce the errors related to the mass measurement. The GERAR Mobile App showed easy to be used since it has intuitive icons and compatibility with the most used operating systems for mobile devices. The responses in communication via Bluetooth were fast. The use of Arduino, a low-cost microcontroller, to automate the monitoring activity allowed estimating the mass of the product and collecting the drying air temperature and relative air humidity data through the DHT22. This sensor showed a good correlation of mass and air temperature readings between the automatic and conventional system, but low correlation for relative air humidity. In general, the automatic data acquisition system monitored in real time the parameters for drying agricultural products in the HSED.

“…Reacting particles are encountered in a broad range of industrial applications of high‐temperature solid–gas reactions including fuel processing, metallurgy, lime, and cement production and separation processes 9 and literature cited therein, as well as chemical looping combustion 10 . High‐temperature reacting particulate media are found in numerous solar thermochemical processes 11,12 . Limestone particles in the size range 1–5 mm were used to demonstrate solar thermal production of lime in directly and indirectly irradiated prototype solar thermochemical reactors 13,14 .…”

The effects of particle size and carbon dioxide concentration on chemical conversion in engineered spherical particles undergoing calcium oxide looping are investigated. Particles are thermochemically cycled in a furnace under different carbon dioxide concentrations. Changes in composition due to chemical reactions are measured using thermogravimetric analysis. Gas composition at the furnace exit is evaluated with mass spectroscopy. A numerical model of thermal transport phenomena developed previously is adapted to match the physical system investigated in the present study. The model is used to elucidate effects of reacting medium characteristics on particle temperature and reaction extent. Experimental and numerical results show that (1) an increase in particle size results in a decrease in carbonation extent, and (2) the carbonation step consists of fast and slow reaction regimes. The reaction rates in the fast and slow carbonation regimes increase with increasing carbon dioxide concentration. The effect of carbon dioxide concentration and the distinction between the fast and slow regimes become more pronounced with increasing particle size.
