Abstract. A novel technique has been developed to measure sulfur dioxide (SO2) using a modification of the existing electrochemical concentration cell (ECC) ozonesonde technology. The current sonde-based method SO2 (i.e., dual-sonde approach) involves launching two ozonesondes together, with one sondes having filter remove at inlet. profile is determined by taking difference between measurement...

In this study, an air heated solar collector (AHSC) dryer was designed to determine the drying characteristics of the pear. Flat pear slices of 10 mm thickness were used in the experiments. The pears were dried both in the AHSC dryer and under the sun. Panel glass temperature, panel floor temperature, panel inlet temperature, panel outlet temperature, drying cabinet inlet temperature, drying ca...

Appropriate technology for the conversion of solar radiation to thermal energy is vital for food dehydration. Commercial producers of dried foods need reliable drying technologies for continuity technologies for continuity of production. However, solar radiation is not available whenever it is needed to drying. This limitation discourages many of these producers from investing in solar technolo...

In recent years, there has been growing interest to use computational fluid dynamics (CFD) for exploring dropletparticles interaction under the turbulent flow of air inside spray dryer systems. The final goal is to predict the dried solid particle size and mass flux distributions under the conditions of collision, coalescence and agglomeration of the droplets and particles. The coarse-grained s...

Breakthrough energy savings were recently projected by a spray-dryer free dairy powder manufacturing process based on superconcentration and granulation. The extent of the recirculation rate for granulation, determines performance. In this study, evolution physical properties during granulation was investigated model system (skim milk microfiltrate) using rheological shear-cell techniques. Resu...

The main goal of this research was to develop a mathematical model for co-current spray drying-assisted encapsulation natural extracts from grape pomace and citrus fruit peels, aiming predict both structural features the retention their bioactive constituents. Model validation performed using laboratory scale dryer, analyzing product in terms moisture content, solids total phenolic compounds re...

This article deals with the integration of a rotary indirect dryer, heated by low pressure extraction steam, into Rankine cycle. The evaluates power generation efficiency steam plant, an integrated which combusts waste biomass high moisture content and is further compared to same plant without dryer. benefits dryer’s are analysed in respect various contents before after drying. evaluation based...
