“…The values of this coefficient were much higher than the unity, which prove the anisotropicity of the phenomena. As reported by Desmorieux et al [16], this anisotropic behavior is similar to avocado which shows an increase of its isotropicity during drying. The similarity between the two materials was in their structure with a compact pasty structure without fibers, which means without structure connecting the cells from one filament to another one.…”

“…The similarity between the two materials was in their structure with a compact pasty structure without fibers, which means without structure connecting the cells from one filament to another one. The use of the microscopic imaging techniques confirmed the formation of crust and cracks during drying [5,16], as it is clearly illustrated in Fig. 4.…”

“…They observed that the dimensions of big contact surface are quite constant. The authors [16] reported this to the composition of the tested alga. As reported, during the drying process; the microorganism synthesizes and releases polysaccharides which have a pseudo-plastic behavior.…”

Kaveh M., Chayjan Amiri R., Esna-Ashari M. (2015): Thermal and physical properties modelling of terebinth fruit (Pistacia atlantica L.) under solar drying. Res. Agr. Eng., 61: 150-161.A laboratory solar dryer was used to study terebinth fruit drying. Two solar collectors were adjusted in east-west directions with the angle of 45°. Initial moisture content of terebinth fruit was dried under natural and forced airflow. In order to predict terebinth moisture content during drying process five mathematical models were used. Colour change and shrinkage of the terebinth samples were calculated. Results showed that the Page model had the best performance in moisture content prediction of terebinth samples. Effective moisture diffusivity of terebinth fruit was increased under forced convection. The lowest colour change and shrinkage of the samples in natural air flow condition were observed. Maximum rupture force and energy values were obtained at maximum airflow velocity. Models were fitted to the experimental data of physical, thermal and mechanical properties of terebinth fruit with high correlation coefficients.Keywords: thin layer; moisture diffusivity; shrinkage; colour; rupture energy Drying is a complex process including simultaneous heat and mass transfer and it can result in significant changes in physical, thermal, and mechanical properties of agricultural and food materials (Koc et al. 2008). These phenomena contribute to moisture removal leading to substantial reduction in mass and volume of product, minimizing packaging, storage and transportation costs (Vega-Galvez et al. 2010). Drying kinetics of material requires simple representations to predict drying behaviour and to optimize drying parameters. Thin layer drying equations have therefore been used to predict drying time and to generalize drying curves (Arumuganathan et al. 2009).Terebinth (Pistacia atlantica L.) is one of the old trees with a long life having small, round and dark green fruit with many nutritional, medicinal and industrial applications that grows in Iran. Mutica, Kurdica and Kabolica are the main terebinth cultivars that grow wild in Iran. Presence of too much moisture in fruit at harvesting time (about 116% d.b.) is a great obstacle for long term storage.Solar drying can be considered as the development of open sun drying which an efficient method of solar energy utilization (Janjai et al. 2009). Sun drying allows the preparation of a new product presenting high quality of colour with translucent appearance.

The search for clean technologies needs to be continued to offer alternatives for achieving sustainable energy production and a sustainable economy. This concern is particularly related to the demands of both producing enough renewable energy to meet future needs and reducing greenhouse gas (GHG) emissions. Microalgae are recognized for several benefits they offer, and in recent years, the use of life cycle assessment (LCA) to evaluate the benefits resulting from microalgae cultivation, harvesting/dewatering, biomass drying, extraction, and byproduct development has stimulated research in this area. Considering the importance of microalgae and clean technologies and the increasing number of publications on these subjects, this review aims to perform bibliometric mapping of such studies from 2008 to 2018. Web of Science and Scopus databases are used to identify leading trends. Visualization of similarities viewer (VOSviewer) software is applied to analyze the interactions among keywords. The results of this study indicate an association of microalgae and clean technologies and demonstrate that LCA is one of the most common tools used for such analyses. Bibliometric mapping provides relevant data to reinforce this association and understand the main bottlenecks that must be overcome in this field for future progress to be made.
