Solar drying of agrobiomass for biopellets production

This paper presents the results of the research devoted to the determination of the conditions of solar drying of agrobiomass waste in open area in Mediterranean climate in Aydin region. The testing was undertaken in the summer season. Drying tests were performed for two type mixtures i.e., sewage sludge and olive mill waste (OMW30) and sewage sludge and animal waste (DMC30). In order to determine the optimum conditions for the process and undertake an analysis of kinetic drying of sewage sludge, a set of tests were performed under variable parameters, i.e. for various thickness of the dried mixture of materials: 5, 10 and 20 cm and with the application of various mixing intensity: no mixing, and 6 times a day. The conducted tests let to the determination of the time interval necessary for the drying in the conditions of summer and also the parameters, which are optimal in terms of the time needed for the solar drying process in open sun drying.
