Honey extraction is the central process in beekeeping of removing honey from honeycomb so that it is isolated in a pure liquid form.

Contents

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.

Centrifugal extraction

This is widely used, especially by commercial beekeepers. Most centrifugal extractors are not suitable for natural combs. This form of extraction is therefore closely associated with vertical hives, which since the mid 1800s have been the most common variety of hive, and are normally furnished with frames including artificial support. Significant labour is required to disassemble the hives and process the honey, then clear up the mess, so it is usual to extract honey from each hive only once a year.

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 supposed 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.

Crush and drain

This method is usual for natural comb without artificial support. Such combs are associated with top-bar hives, especially horizontal hives which allow for continuous harvest through the season.

StepWarré hiveTrough top bar hive
1Remove roof and quiltRemove cover
2Remove 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:

Flow frames

Flow frames consist of plastic honeycomb lattice. Bees fill in the vertical gaps with beeswax and the cells with honey. When the combs are full of ripe honey, the mechanism of the frames is activated, the vertical gaps are moved to offset by one half of a cell. This breaks the wax seal and allows the honey to flow down through the cells into a channel at the base of each frame and out into a collection vessel. The bees normally show no sign of disturbance, and any bees in the flow frame at the time are not harmed. Clean honey can be produced and filtration is not normally required. [2] The system is then reset and the bees clean up any remaining honey, remove the capping, and refill the cells, beginning the process again.

Each colony that is to use flow frame extraction must be furnished with flow frames, and their cost limits their appeal to existing commercial apiarists. However, new entrants to small beekeeping may find that the greater cost per hive of flow frames is more than off-set by saving time, labour, space, mess, and disturbance to the bees. Expensive extraction equipment (centrifuge, filters, working and storage space) is not required. [2] [3]

Beeswax Natural wax produced by honey bees of the genus Apis

Beeswax is a natural wax produced by honey bees of the genus Apis. The wax is formed into scales by eight wax-producing glands in the abdominal segments of worker bees, which discard it in or at the hive. The hive workers collect and use it to form cells for honey storage and larval and pupal protection within the beehive. Chemically, beeswax consists mainly of esters of fatty acids and various long-chain alcohols.

Honeycomb

A honeycomb is a mass of hexagonal prismatic wax cells built by honey bees in their nests to contain their larvae and stores of honey and pollen.

Beehive

A beehive is an enclosed structure in which some honey bee species of the subgenus Apis live and raise their young. Though the word beehive is commonly used to describe the nest of any bee colony, scientific and professional literature distinguishes nest from hive. Nest is used to discuss colonies that house themselves in natural or artificial cavities or are hanging and exposed. Hive is used to describe an artificial/man-made structure to house a honey bee nest. Several species of Apis live in colonies, but for honey production the western honey bee and the eastern honey bee are the main species kept in hives.

Beekeeper

A beekeeper is a person who keeps honey bees.

Beekeeping Human care of honey bees

Beekeeping is the maintenance of bee colonies, commonly in man-made hives, by humans. Most such bees are honey bees in the genus Apis, but other honey-producing bees such as Melipona stingless bees are also kept. A beekeeper keeps bees in order to collect their honey and other products that the hive produce, to pollinate crops, or to produce bees for sale to other beekeepers. A location where bees are kept is called an apiary or "bee yard".

Bee brood

In beekeeping, bee brood or brood refers to the eggs, larvae and pupae of honeybees. The brood of Western honey bees develops within a bee hive. In man-made, removable frame hives, such as Langstroth hives, each frame which is mainly occupied by brood is called a brood frame. Brood frames usually have some pollen and nectar or honey in the upper corners of the frame. The rest of the brood frame cells may be empty or occupied by brood in various developmental stages. During the brood raising season, the bees may reuse the cells from which brood has emerged for additional brood or convert it to honey or pollen storage. Bees show remarkable flexibility in adapting cells to a use best suited for the hive's survival.

Horizontal top-bar hive Type of beehive

A top-bar hive is a single-story frameless beehive in which the comb hangs from removable bars. The bars form a continuous roof over the comb, whereas the frames in most current hives allow space for bees to move up or down between boxes. Hives that have frames or that use honey chambers in summer but which use similar management principles as regular top-bar hives are sometimes also referred to as top-bar hives. Top-bar hives are rectangular in shape and are typically more than twice as wide as multi-story framed hives commonly found in English speaking countries. Top-bar hives usually include one box only, and allow for beekeeping methods that interfere very little with the colony. While conventional advice often recommends inspecting each colony each week during the warmer months, heavy work when full supers have to be lifted, some beekeepers fully inspect top-bar hives only once a year, and only one comb needs to be lifted at a time.

Langstroth hive

In modern American beekeeping, a Langstroth hive is any vertically modular beehive that has the key features of vertically hung frames, a bottom board with entrance for the bees, boxes containing frames for brood and honey and an inner cover and top cap to provide weather protection. In a Langstroth hive, the bees build honeycomb into frames, which can be moved with ease. The frames are designed to prevent bees from attaching honeycombs where they would either connect adjacent frames, or connect frames to the walls of the hive. The movable frames allow the beekeeper to manage the bees in a way which was formerly impossible.

Comb honey

Comb honey is honey intended for consumption by humans, which is still contained within its original hexagonal-shaped beeswax cells, called honeycomb. It has received no processing, filtering, or manipulation, and is in the state that honey bees have produced it.

Hive frame

A hive frame or honey frame is a structural element in a beehive that holds the honeycomb or brood comb within the hive enclosure or box. The hive frame is a key part of the modern movable-comb hive. It can be removed in order to inspect the bees for disease or to extract the excess honey.

Honey super

A honey super is a part of a commercial or other managed beehive that is used to collect honey. The most common variety is the "Illinois" or "medium" super with a depth of 6​58 inches, in the length and width dimensions of a Langstroth hive.

Swarming (honey bee)

Swarming is a honey bee colony's natural means of reproduction. In the process of swarming, a single colony splits into two or more distinct colonies.

Honey extractor

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.

Hive management in beekeeping refers to intervention techniques that a beekeeper may perform to ensure hive survival and to maximize hive production. Hive management techniques vary widely depending on the objectives.

L. L. Langstroth

Rev. Lorenzo Lorraine Langstroth was an American apiarist, clergyman, and teacher, and considered to be the father of American beekeeping. He created the modern day Langstroth hive.

Beekeeping in the United States

Beekeeping in the United States dates back to the 1860s.

Wax foundation

Wax foundation or honeycomb base is a plate made of wax forming the base of one honeycomb. It is used in beekeeping to give the bees a foundation on which they can build the honeycomb. Wax foundation is considered one of the most important inventions in modern beekeeping.

Flow Hive

Flow Hive is a beehive designed to allow honey to be extracted simply by turning a knob: the hive does not have to be opened and the bees are not disturbed as in normal extraction.

Hive tool

A hive tool is a handheld multipurpose tool used in maintaining and inspecting beehives. Hive tools come in multiple variants and styles, and is intended as an all-in-one tool for beekeepers.

Franz Hruschka

Franz Hruschka also known as Franz von Hruschka or Francesco De Hruschka or František Hruška was an Austrian/Italian officer and beekeeper known as the inventor of the honey extractor, an invention he presented in 1865 at the Brno Beekeeper Conference.
