Some beekeepers will also harvest (before uncapping the honey) the propolis, a resinous material bees gather to glue the frames together; propolis is used for its medicinal properties. Once uncapped, the frames are then placed in a honey extractor, which spins them so that most of the honey is removed by centrifugal force. Care must be taken to ensure that all frames are loaded correctly, as the comb is angled slightly upwards to prevent
