Abstract:
Palm kernel oil is a vegetable oil widely used in West Africa as skin moisturizer, cream, in the manufacture of perfumes and also as food additives. The oil deteriorates during production, exposure to air, water and poor storage system notable in West Africa. This rancidity of the oil is as a result of the formation of butyric and formic acids when aldehyde, formaldehyde and butyraldehyde undergo further oxidation after unsaturated fatty acid from the oil form peroxy radicals in air. This research work looks at removing the odouriferous materials from the crude palm kernel oil with an incline plate (aluminum) deodorizer placed at angles 30, 35 4550 55and 60 to the horizontal. The deodorizer uses natural convection process occurring around it as the means by which volatiles on the heated oil are removed as it flows down the deodorizer. Results from the experiment carried out and calculations showed that the best deodorized palm kernel oil was at an inclination of 30o to the horizontal. And the highest average Grashof number value of and for the oil flow surface and non-flow surface of the deodorizer was obtained respectively. Angle 30 O also gave the least flow rate and least peroxide value of 2.1 mE/kg. Thus at angle 30o more heat and volatiles are lost from the oil as it flows down the incline plate compared to other angles of inclinations (35 4550 55and 60).
