Kudra T., Ratti C.Process and Energy Optimization in Drying of Foamed Materials // Scientific article. Journal "Transactions of the TSTU", vol. 14 , Tambov. TSTU publisher house , 2008. (pdf-file) Abstract: The paper deals with optimization of drying time and energy consumption in foam-mat drying of liquid bio-materials. A clarified apple juice mixed with methylcellulose in mass concentrations 0,5; 1,0; 2,0 and 3,0 % was whipped in a blender to generate foams of different density varying from 0,21 to 0,45 g/cm3. The foam samples in layers of 6, 12 and 26 mm thick were then dried in a drying tunnel using air at 55 °C flowing past the sample surface at a superficial velocity of 0,7 m/s. Experimental data were interpreted in terms of drying kinetics and energy performance. It was found that the drying rate of foamed juice depends on foam density and its characteristics, as well as on the layer thickness. Shorter drying times were obtained for thinner layers of foams of the same density. A distinct minimum of a drying time was obtained for foam density of 0,21 g/cm3 induced with 1 % methylcellulose. This foam exhibited the highest drying efficiency and the lowest energy consumption.
