Development of low cost agarwood essential oil extraction system for agar tree growers in Bangladesh

This experiment was conducted to bring in a suitable and economic agarwood oil extraction method for Agar tree (Aquilaria agollocha) growers in Bangladesh. Agarwood was collected from Fotikchori upazila of Chittagong district and a prototype of hydro-distillation extraction chamber was developed at the lab of Department of Farm Power and Machinery, Bangladesh Agricultural University, Mymensingh, Bangladesh during January to March 2013. Using the prototype, 7 ml of agarwood oil was extracted from 15 kg matured agarwood. It was found from the calculation that the developed system can bring yearly benefit of Tk. 7,78,389 with benefit-cost ratio as 2.33. This development was, therefore, proven very beneficial for Bangladeshi agar tree growers
