Title: A new type of modular dryer combining solar energy and producer gas

The main concept of this research is to develop a flexible modular dryer that combines two different sources of non-conventional energy. In this study, solar energy and producer gas generated by an up-flow charcoal gasifier were considered. The drying system was set out by using a 0.6 m{sup 3} modular cabinet supporting a solar collector of 2.5 m{sup 2} surface area. 16 kg of charcoal was used in each batch to feed the gasifier. The experiment was performed for drying beef that required two different stages of drying temperature: the first, which used producer gas requires approximately 60 C for four hours and the second used solar energy at 40 C for six hours. The energy consumed for drying 16 kg of beef was 7.57 MJ/kg H{sub 2}O evaporated which obtained from solar energy, producer gas and blowers in percentages of 8.72%, 31.44% and 59.84%, respectively.
