This paper presents a research done on the thin layer drying behaviour of parboiled breadfruit (treculia africana var inversa) seeds at 30% Moisture Content (w b ) and varying air temperatures of 55 65 and 75oC at air velocities of 0 6 1 0 and 1 5 m/s In order to select a suitable form of the drying curve 5 different thin layer semi theoretical drying models were fitted to Dec 17 2009The efficiency of polymer based bulk heterojunction (BHJ) solar cells mainly depends on the film morphology of the absorption layer and the interface properties between the stacked layers A comparative study using atomic force microscopy (AFM) and optical in situ thin film drying measurements is performed The strong impact of distinct drying scenarios on the polymer:fullerene BHJ layer

Effect of ohmic blanching on drying kinetics

This study aims to perform an optimization of process parameter for ohmic blanching of garlic to focus on the drying characteristics of the garlic powder at different temperatures Comparative analyses on physicochemical and functional properties of differentially blanched garlic powder are carried out The browning intensity was found to be lesser in garlic with ohmically blanched at

The effect of temperature on drying of bitter leave and scent leave was studied using laboratory moisture content analyzer at temperatures of 50 oC 60 oC 70 oC and 80 oC The falling rate phenomenon was observed for both bitter leave and scent leave The thin layer drying models were fitted to the experimental moisture ratio data

thin-layer drying models have been widely in use Several thin-layer drying models available in the literature for explaining drying characteristics of agricultural products These models can be categorized as theoretical semi-empirical and empirical Moreover the drying kinetics of food

A sauna drying technique—the solar drier was designed and imposed constructed and tested for drying of seaweed The seaweed moisture content was decreased around 50% in 2-day sauna Kinetic curves of drying of seaweed were known to be used in this system The non-linear regression procedure was used to fit three different drying models The models were

drying curve was more like that reported for thick than for thin-layers vegetable fibers (concave downwards shape) (Langrish 2008) This could be explained by the low diffusion coefficient of water in the raffia fiber Fig 1 Effect of air temperature on the drying kinetics of Raffia textilis fibers Air velocity: 1 m s-1 Fig 2

The effect of hot water blanching treatment on thin layer drying kinetics of aonla shreds was studied at drying air temperatures of 50 55 and 60 C with the air velocity of 1 2 m/s The drying time decreased with the increase in air temperature and blanching

This work was conducted to study the thin-film drying kinetics of mango (mangifera indica L ) using a modular electrical dryer licking countercurrent and forced convection Drying experiments were carried out in the Laboratory of Energetics and Applied Thermal (LETA) of the National School of Agro-Industrial Sciences of the University of Ngaoundere under different conditions of drying

dried Our work consisted in conducting several drying experiments to investigate the thin-layer drying kinetics of tomato okra potato and mango in a solar tunnel dryer Simulation models as a valuable tool for prediction of performance of solar drying systems [6] were used to determine key drying constants

Drying of thin layer white mulberry fruits was studied using a solar tunnel dryer under the ecological conditions of Isparta Turkey An experimental solar dryer with a flat plate solar collector has been constructed at the Department of Agricultural Machinery and Technologies Engineering at Suleyman Demirel University

A natural convection solar tunnel dryer comprising three major units a solar collector unit a drying unit and a vertical bare flat-plate chimney was constructed No-load tests with a horizontal configuration of air entry into the collector resulted in a bidirectional air flow in the dryer To correct this undesirable situation an air guide at the collector was incorporated to ensure

An experimental solar tent dryer under natural convection was used to study thin layer drying kinetics of amaranth (Amaranthus cruentus) grains Drying of grains in the dryer was carried out on a drying rack having two layers top and bottom The ambient temperature and relative humidity ranged from 22 6-30 4C and 25-52% respectively while the inside temperature and

The aim of the study was to model the solar drying characteristics of the leaves of Amaranthus hybridus and Xanthosoma sagittifolium dried in thin layers Fresh leaves were obtained from Centre for Biodiversity Utilisation and Development (CBUD) farms trimmed into strips of 0 3 cm x 3 cm and loaded into cabinet solar dryers up to a 5 mm layer

Levenberg-Marquardt The coefficient of determination R 2 was one of the primary criteria used to select the best model to describe the direct solar drying curves of mangoes [15] A 2016 comprehensive review by Onwude et al suggests that there are now 22 semi-theoretical and empirical thin-layer drying models [16]

The obtained solar drying curves were fitted with nine different thin-layer drying models (table 1) [9-16] The correlation coefficient (r) the reduced chi-square (X2) were the statistical parameters used for selecting the best equation to describe the thin-layer drying curves of Urtica dioica leaves Table 1
