the present study investigated the influence of air temperature and velocity on the drying kinetics and specific energy consumption during fluidized bed drying of soybean at 80, 100, 120 and 140ºc and airflow rates of 1.8, 3.1 and 4.5 m s-1. six mathematical models for describing the fluidized bed drying behavior were investigated. the value of the drying rate coefficient (k) increased with inc...

Abstract The effects of different dehydration temperature (35, 50 and 70 °C) carrot slice thickness (3, 6, 9 mm), at the constant (hot) air speed mass load, on moisture ratio ( MR ) drying DR in thin layer convective process were investigated. mathematical models Modified Page, Logarithmic, Two-term (for ), Gauss model most appropriate. Based obtained results for R 2 RSME , optimal parameters s...

• Solar tunnel dryer improved the drying rate by 33.3% compared to open sun drying. The effective moisture diffusivity of solar increased 34.9%. both varieties varied from 2.94 E−09 4.47E−09 m 2 s −1 . overall system efficiency was in range 24.12–31.3%. net CO mitigation 10.9 13 tons per year. An indirect two-stage has been developed study characteristics two chili pepper varieties. effect laye...

An evacuated tube solar collector drier is designed and developed to study analytically and experimentally drying kinetics of Thompson seedless grapes in Pune, India. Drying experiments are carried out in the month of April- June for continuous three years from 2013-2015. During the experimentation, temperatures of hot and cold air at various places, ambient relative humidity and humidity varia...

Mathematical and numerical modeling of drying coating layers is of interest to both industrial and academic communities. Compositional changes that occur during the drying process make the implementation of practical and efficient numerical models rather difficult. In this paper we present a three-dimensional mathematical and numerical model based on the lubrication approximation for the flow o...
