Relative Humidity Effect on the High-Temperature Drying of Shelled Corn

Thin- layer drying of diced cassava roots

“…At constant temperature, pressure and hmidity, this equation is valid if drying is characterized by "falling-rate" regime (Nellist, 1976) which is a characteristic of drying of low moisture content products such as grains. As quoted in Sun and Woods (1994), this model has been successfuly used for barley (Sharp, 1982;Bruce, 1985), wheat (Simmonds et al, 1953), paddy (Kachru et al, 1980), and shelled corn (Westerman et al, 1973). The drying constants in thin-layer drying equations vary with temperature Verma et al, 1985).…”

Moisture Diffusivity and Energy Consumption during Microwave Drying of Plaster of Paris

“…In this study, the experimental drying data of plaster of paris at different initial moisture contents, drying time and output power levels of microwave oven were analyzed to identify the most convenient model among the 9 different expressions (Table 1), defining drying rates as proposed by several authors (Ayensu, 1997;Lui and Bakker, 1997;Agarwal and Singh, 1977;Zhang and Litchfield, 1991;Pal and Chakraverthy, 1997;Westerman et al, 1973;Hederson, 1974;Yagcioglu et al, 1999;Ozdemir and Devres, 1999;Wang and Singh, 1978;Kaseem, 1998;Yaldız and Ertekin, 2001b;Verma et al, 1985;Sharaf-Eldeen et al, 1980;Midilli et al, 2002). Comparing the drying phenomenon with Newton's law of cooling, the drying rate will be approximately proportional to the difference in moisture content between the material being dried and the equilibrium moisture content at the drying conditions, which can be expressed in terms of moisture ratio (MR),:…”

A Single-Layer Model for Far-Infrared Radiation Drying of Onion Slices

“…A few selected empirical and semi-empirical single-layer models have been employed to describe the drying process of biological products (Ross and White, 1972;Westerman et al, 1973;Chinnan, 1984;Pathak et al, 1991;Henderson, 1974;Wang and Singh, 1978).…”
