Honey extraction
Honey extraction is the central process in beekeeping of removing honey from honeycomb so that it is isolated in a pure liquid form.
Normally, the honey is stored by honey bees in their beeswax honeycomb; in framed bee hives, the honey is stored on a wooden structure called a frame. The honey frames are typically harvested in the late summer, when they will be most filled with honey. On a completely filled frame, the cells will be capped over by the bees for storage; that is, each cell containing honey will be sealed with a capping made of beeswax.
Extraction
The first step in the extraction process is to break or remove all of the cappings. This may be accomplished using an automated uncapper machine or with a manually-operated uncapping knife. Usually, these tools are used together, along with a pronged cappings fork. To facilitate cutting off these wax cappings, the knife is often heated. The removed bits of wax, called cappings, are rich in honey which can be slowly drained off with the help of some heating. This 'cappings wax' is very valuable and often used to make candles or other products. Automated uncapping machines normally work by abrading the surface of the wax with moving chains or bristles or hot knives. This, while messy, makes the process easier than doing this task manually.
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 the honey flowing out; if loaded incorrectly, this can also prevent the honey flowing out during extraction. Once extracted, the resulting honey will contain bits of wax and must be passed through a screen so that clean liquid honey results.
Any honey that can't be harvested, which includes crystallized honey left on the frames after extraction, or honey that is not capped over, and therefore unripened, is usually placed back into the colonies for the bees to clean up. Some beekeepers place wet frames outside so that it will be reclaimed by the bees. This must be done early in the morning or late in the evening as the bees will aggressively harvest such a rich source. Care must be taken so that this is done at a time when food is not scarce, or else bees from differing colonies will fight over the honey. In addition, this can spread disease from contaminated frames and can be a potential problem; this technique is not advised.
The extraction process is typically done inside a specialized room, or honey house, that can be heated (since hot honey will flow faster), with all of the necessary tools nearby and is washable. The room must be well sealed, as bees (and other insects) will eagerly try to enter and gather the honey. It is important to remember that honey is a food product.
The table below outlines the extraction process.
| Honey Harvest Process steps | Method description | Alternative Method 1 | Alternative Method 2 |
|---|---|---|---|
| 1 | Remove hive outer cover from top of the beehive super | ||
| 2 | Remove hive inner cover from top super | ||
| 3 | If no queen excluder was used, inspect frames for brood and only remove frames that are without brood. | Remove only frames that are 80% capped and without brood | Remove all frames that have honey but no brood |
| 4a | Add fume board to top of hive to force bees into lower parts of hive. | Remove super and use air blower to force bees from frames | Remove frames one by one and manually brush off bees |
| 4b | Repeat steps 3 and 4a until all supers are removed | ||
| 5 | Transport frames in supers to honey house | ||
| 6 | Heat and dehumidify frames in honey house for 1– 2 days | Do nothing | |
| 7 | Use refractometer to check that moisture content is below 18.5% | Do nothing | |
| 8 | Remove the wax cap on capped honey manually (Uncap) | Uncap mechanically | Cut out comb honey |
| 9 | Load honey extractor | Load honey press | Set comb honey chunks on drip pan to drain off honey from cutting edge |
| 10 | Turn on honey extractor motor | Manually turn extractor crank | |
| 11 | Run extracting process for several minutes | ||
| 12 | Remove extracted frames from extractor | ||
| 13 | Empty extractor sump: Let collected honey flow into storage container via gravity. | Empty extractor sump: Pump honey using a mechanical pump | |
| 14 | Filter honey | Let wax and other particles settle out | Run raw honey through a separator |
| 15 | Grade honey | Do nothing | |
| 16 | Bottle honey | Package comb honey | |
| 17 | Market and sell honey | Use honey for home consumption |
Good deepthi
Deepthi or deepu come in horizontal (trough) and vertical (of which the Warré hive is an example). Trough hives allow for continuous harvest through the season, while Warré hives (per Abbé Warré) are intended to be harvested only at the end of the season.
| Step | Warré hive | Trough top bar hive |
|---|---|---|
| 1 | Remove roof and quilt | Remove cover |
| 2 | Remove boxes of comb from the top of the hive, being sure to leave sufficient stores for the colony to overwinter on. | Remove mostly full combs. |
Once the combs are removed from the hive, they can be processed in several ways:
- Encase them in a cage and use a centrifugal extractor as with framed combs. This was done in the early twentieth century.[1]
- Preserving as-is to be consumed in comb form.
- Crushing the combs, straining the honey, and processing the beeswax.
