Abstract

Honey is the most important primary product of beekeeping both from a quantitative and an economic point of view. It was also the first bee product used by human kind in ancient times. The history of the use of honey is parallel to the history of man and virtually every culture evidence can be found of its use as a food source and as a symbol employed in religious, magic and therapeutic ceremonies is an appreciation and reference it owes among other reasons to its unique position until very recently, as the only concentrated form of sugar available to man in most parts of the world. The same cultural richness has produced an equally colorful variety uses of honey in other product. Because of these important reasons, honey used to be extracted (collected) to meet the demand both in raw form or as valued added to other products. The economic and medicinal importance of honey warrants the development of low cost, locally made and portable extractor that can be accessed by the honey farmers. The availability of this machine will increase honey production into the market, relief the honey farmers of their drudgery in producing honey, create self employment for the jobless and finally increases the economy of Nigeria through exportation of this honey and its products. The physical characteristics (viscosity, density, hyroscopicity; surface tension) and thermal properties of honey were considered before the design and fabricate of this extractor. The design was made simple and manually operated which can be installed at home or farm where breeding of honey bees is possible. It is a chain driven system with sprockets of small diameter of 55 mm and big diameter 343 mm and teeth number of 18 and 113 respectively with chain pitch of 99.525mm of type number 150D/N=06B-2Rdon DR957. The chain system was mounted on a vertical central solid shaft of diameter 25 mm to this shaft was the honey comb net bucket of hexagon shape with six segments was welded. A full turn will give the net bucket housed in a cylindrical container (drum) speed of 200 rpm when loaded. While the design driven force is 0.7054N. The volume of honey collected was 9.0 litres while the one collected from imported honey extractor was 11.0 litres when 15 kg of honey comb was used to fill their net baskets under the same number of turns. This proved the local fabricated extractor to be 82% relative efficient. The cost of production was twenty five thousand (25,000) naira only which is one hundred and sixty US dollars ($155.28) equivalent of current exchange rate of N161 Naira per US dollar. This amount took care of bought out component, machining, non machining, and material costs with 10% profit margin. The only limitation is that it is not electrically driven, has the advantage of being used in both urban and rural areas where there is no electricity.
