The structural parameters of a grain dryer are directly related to the its energy consumption and quality formation. Therefore, based on Ergun model, air state uniformity evaluation method, effect changes in ventilation area airflow resistance, drying consumption, efficiency theoretically experimentally studied this work under same initial weight flux. results show that conditions temperatures ...

Optimal curcumin delivery for medicinal applications requires a drug delivery system that both solubilizes curcumin and prevents degradation. To achieve this, curcumin has been encapsulated in submicrometer chitosan/Tween 20 particles via a benchtop spray-drying process. Spray-drying parameters have been optimized using a Taguchi statistical approach to minimize particle size and to favor spher...

A constitutive model is derived from theory of elasticity for predicting ultimate drying shrinkage of concrete. The model was extended by incorporating the semiempirical composite model proposed by Hirsch and Dougill for predicting Young's modulus of concrete. Their composite model is the geometric mean of Paul's upper and lower limit boundaries of a twophase composite. According to the shrinka...

Drying of green peas in a Fluidized Bed Dryer (FBD) with inert particle, heated by combined sources of hot air and InfraRed (IR) radiation, has been experimentally and theoretically studied. For this purpose, an experimental set up was constructed. This setup was composed of a cylindrical bed dryer containing some inert particles which are fluidized by hot air. Some infrared lamps were also pla...

This paper focuses on biomass drying for the design and operation of an indirect dryer used in a power plant. Indirect is not as well described process direct drying, especially when preparation energy processes, such combustion or gasification. Therefore, it necessary to choose suitable model describing evaluate its applicability this purpose. The aim identify parameters that most significantl...

To my parents i Acknowledgements I would like to express my deepest gratitude to my principal supervisor Prof. Dr.-Ing. habil. Evangelos Tsotsas for his outstanding advices and support. I wish to express my deep thanks to my co-supervisor Dr. Thomas Metzger and his wife Mrs. Nicole Metzger not only for their very important guidance, constant encouragement to my scientific progress but also for ...

in this work, a hybrid gmdh–neural network model was developed in order to predict the moisture content of papaya slices during hot air drying in a cabinet dryer. for this purpose, parameters including drying time, slices thickness and drying temperature were considered as the inputs and the amount of moisture ratio (mr) was estimated as the output. exactly 50% of the data points were used for ...
