Have you ever spun honey? This is a centrifuge. After wax cappings have been removed from each side of the frame, they are loaded into a machine like this which is either electric or human powered (using a crank system). This requires an even balance of frames (meaning you cannot spin just one frame in the machine). Then the honey is strained to remove excess bits of wax. Pollen is left in the honey and we never heat the honey beyond the temperature sometimes required to keep it liquid.
