I got the Swienty World honey extractor
http://swienty.com/default.asp?pid=1&id=108600, available from Better Bee for ~$250) and tried it for the first time. It is different from the extractors that are familiar to us in that the frames are laid flat inside the extractor so that both sides of the frame are radially extracted at the same time. Three deep frames can be extracted at one time. While the extractor is hand cranked, this is not a major inconvenience because once you crank it up to speed it takes little effort to maintain that speed due to the large rotation radius. It took me about 5 minutes (it was cold) to extract 3 frames. Frames were extracted cleanly. In fact, I found that if I cranked it too fast the centripetal force would compress the combs against the top bars of the frames. The top cover of the machine is made of clear plastic and light enters easily so you can watch the extracting progress. All of the components of the machine were easily disassembled for cleaning. The large diameter of the machine makes it a little unwieldy to carry around because you have to walk sideways to see where you are walking. You also need long arms to reach around it to pick it up, so this might be a problem for small people (I am over 6 ft (1.85 m) tall). Some things I would suggest for improvement are (1) an instruction manual, (2) an eye bolt on the bottom to hang the machine on the wall for storage, (3) thumb screws or wing nuts in place of the phillips head screws that secure the crossbar to the body, (4) different packing tape – the adhesive on the packing tape they use is very difficult to remove. I found 100% isopropyl alcohol to be the best solvent for removing this adhesive.
Advantages:
Low cost
Fast
Easy to use
No electricity required
Disadvantages:
Unwieldy to carry around
No instruction sheet
All things considered, I really liked the Swienty World extractor. I prefer it over the Dadant extractor that many of us currently use. Now all we need is a fast, easy, inexpensive decapper!
BTW, the picture in the Betterbee catalog of the Swienty World extractor is of one of the first prototypes. Go to the Swienty website listed above to see the one actually sold.
