With a view to contributing to the improvement of the quantitative and qualitative production of honey, a human-powered centrifugal extractor was designed, manufactured and tested at the Agricultural Engineering laboratory of the University of Dschang. The design was based on standard frame sizes for modern hive supers, mechanical design standards and honey quality standards. The tests were carried out with frames of Langstroth hive supers from an apiary in the town of Bafoussam I. Apart from the gear system constructed from cast iron, the other components of the puller were constructed from galvanized and stainless steel. The components of this machine are as follows: (a) a tank with a diameter of 650 mm, a height of 800 mm and a thickness of 1 mm; (b) a rotating basket with a diameter of 600 mm, a height of 550 mm and a thickness of 6 mm; (c) a transmission system consisting of a bevel gear, transmission ratio 1: 4, module 1.5 mm with a driving wheel and a pinion; (d) two 20 mm internal diameter ball bearings; (e) a 20 mm diameter transmission shaft; (f) a centering and clamping plate made of length 650 mm, width 80 mm and thickness 5 mm. The machine stand has a diameter of 651 mm, a height of 1000 mm and a diameter of 21 mm. Three extraction tests were carried out. The results obtained were as follows: average extraction rate: 78.36%; average hourly capacity: 35.35 kg/h, average mass of solid particles: 0.098 g/100 g of honey. The fabricated extractor will allow beekeepers to make several harvests over the year because the bee cells are not destroyed during the extraction. This preservation of aveoles will lead to the sowing of other hives after extraction. This machine is simple to operate and maintain; you just need to clean it and lubricate the gear system and the bearings regularly.

Abstract: (french)
Dans l’optique de contribuer à l’amélioration de la production quantitative et qualitative du miel, un extracteur centrifuge à motricité humaine a été conçu, fabriqué et testé au laboratoire de Génie Agricole de l’université de Dschang. La conception a été basée sur les dimensions standards des cadres des hausses de ruches modernes, des normes de conceptions mécaniques et des normes de qualité du miel. Les tests ont été effectués avec les cadres de hausses des ruches Langstroth provenant d’un rucher de la ville de Bafoussam Ier. En dehors du système d’engrenage construit en fonte, les autres composants de l’extracteur ont été construits en acier galvanisé et inoxydable. Les composants de cette machine sont les suivants: (a) un réservoir de diamètre 650 mm, de hauteur 800 mm et d’épaisseur 1 mm; (b) un panier rotatif de diamètre 600 mm, de hauteur 550 mm et d’épaisseur 6 mm; (c) un système de transmission constitué d’un engrenage conique, de rapport de transmission 1: 4, de module 1,5 mm avec une roue menante et un pignon; (d) deux roulements à billes de 20 mm de diamètre interne; (e) un arbre de transmission de diamètre 20 mm; (f) une plaque de centrage et de serrage fait de longueur 650 mm, de largeur 80 mm et d’épaisseur 5 mm. Le support de la machine a un diamètre de 651 mm, une hauteur de 1000 mm et un diamètre 21 mm. Trois tests d’extraction ont été effectués. Les résultats obtenus ont été les suivants: taux moyen d’extraction: 78,36 %; capacité moyenne horaire: 35,35 kg/h, masse moyenne de particules solides: 0,098 g/100 g de miel. L’extracteur fabriqué permettra aux apiculteurs de faire plusieurs récoltes sur l’année car les alvéoles d’abeilles ne sont pas détruites pendant l’extraction. Cette préservation d’avéoles conduira à l’ensemencement d’autres ruches après extraction. Cette machine est simple à utiliser et à entretenir; il suffit juste de la nettoyer et de graisser régulièrement le système d’engrenage et les roulements.
