A honey extractor is a mechanical device used in the extraction of honey from honeycombs. A honey extractor extracts the honey from the honey comb without destroying the comb. Extractors work by centrifugal force. A drum or container holds a frame basket which spins, flinging the honey out. With this method the wax comb stays intact within the frame and can be reused by the bees. Bees cover the filled in cells with wax cap that must be removed (cut by knife, etc.) before centrifugation. ==Types of extractor== Extractors are either tangential or radial depending on how the frames are put into the basket. Radial baskets have the top bar of the frame facing outwards while tangential baskets have one side of the comb facing outward. Large commercial extractors are radial and rely on the upward slope of the comb cells. This slope allows to extract honey by applying centrifugal force toward the upper edge of the comb (opposite to the direction of gravity while in the hive). The amount of work during extraction is reduced in the radial type because the frames do not have to be turned over to extract the honey from the other side of the comb (however some extractors are capable of turning combs automatically). Hobbyist extractors can be hand or electric motor powered. If the extractor is hand powered, it often has accelerating gear to spin with less effort. The smallest extractors hold two frames. The largest commercial extractor holds more than a hundred frames. During the extraction process the honey is forced out of the uncapped wax cells, runs down the walls of the extractor and pools at the bottom. A tap or honey pump allows for the removal of honey from the extractor. Honey must be removed in time and always stay below the rotating frames as otherwise it prevents extractor from spinning with sufficient speed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「honey extractor」の詳細全文を読む スポンサード リンク
