The percolator, largely made of stainless steel has a hopper which opens into the extraction chamber through an 80 mm chute. The device is capable of holding about 10 kg of oilseed flakes immersed in solvent. The extraction chamber is equipped with an oil-tight base flange, which bears a filter to drain out the miscella and through which the defatted material may be discharged. The machine which was tested with groundnut, soybean and moringa seeds gave extraction efficiencies of 98.1, 95 and 93.4%, respectively. A device of this nature saves the monotonous routine involved in the use of soxhlet apparatus for defatting oilseeds when large quantity of oil is required for experimental purpose. http://pubs.sciepub.com/ajfst/4/6/3/ajfst-4-6-3.pdf oilseeds oil extraction percolator defatting
