| Summary: | The aim of this study is to investigate application of Midilli-Kucuk thin layer drying model for convective and microwave drying of sugar beet pulp. Also air followed by a microwave finish drying was investigated. As the parameter of quality of dried sugar beet pulp water holding capacity was investigated. The drying took place in falling rate period although a short constant period was observed during hot air drying at 65 C. The experimental moisture ratio data were fitted to Midilli-Kucuk model and assess according to three statistical criteria: reduced chi-square, root mean square error and residual sum of squares. This model satisfactorily described the drying characteristic of sugar beet pulp. Water holding capacity was evaluated as the quality parameter. It decreased with increase of drying temperature as well as microwave power. The highest value was obtained for microwave finish drying. |
