Extraction Techniques
(From Fundamentals of Beekeeping)
Removing honey from the combs is difficult for the hobbyist since
there is no simple, neat, and inexpensive way of doing so. Most
important, all utensils, containers, and other items that come
in contact with the honey must be kept clean during the operation.
The first step in extraction is the removal of wax cappings. Combs
of honey are uncapped on both sides with a sharp knife heated
by electricity, steam, or by dipping it in hot water. A thin layer
of wax and honey is cut from the surface of each comb with a back-and

forth sawing movement, as the knife is held against the top and
bottom bars of the frame. (See Figure 46.) First uncap one side,
then turn the frame and uncap the other side. The frame is best
held by pivoting the end bar on a point of a nail that is supported
by a strip of wood laying across the top of the container which
receives the cappings. Hold the frame at an angle, so the cappings
fall free of the comb into the container below. A capping scratcher
or fork is used to break the cappings in the low areas of the
comb. Power uncappers with vibrating knives and automatic uncapping
machines are available for large commercial operations.
Since the cappings contain a large amount of honey after they
are cut from the combs, it is important to have some way of separating
the honey from the wax. Allowing the cappings to drain in a screened
box or wire basket is a convenient way for the small operator.
The simplest uncapping box for draining the cappings is made from
a clean hive body with a screen or queen excluder attached at
the bottom. This unit is placed over a tank so that the honey
is collected below. In larger operations, capping melters or spinners
are used for reclaiming the honey.
The most primitive way of removing honey from the cells is to
cut the combs from the frames and let the honey drain from the
cells. To expedite the process, the combs are crushed and the
honey squeezed out by hand. Then the final mixture is strained
through a coarse sieve or cloth such as cheesecloth.
the best method of producing liquid honey requires an extractor
that uses centrifugal force to spin the honey from the cells.
Various types and sizes of honey extractors are manufactured commercially.
The beekeeper may purchase an extractor, rent the equipment, find
a beekeeper who does custom extracting, or build an extractor.
The small-scale beekeeper often uses a two- or four-frame basket
extractor, which may be either a reversible or non reversible
type. The uncapped combs are placed vertically in the baskets
that support them. In the nonreversible type, the combs must be
reversed by hand to extract the honey from the other side of the
comb. Reversible extractors have baskets that pivot to extract
either side of the comb without lifting it. Either the hand-or
power-driven baskets are turned slowly at first. If the extractor
is turned too rapidly, the weight of the honey will break the
combs. The combs are spun until about half the honey is removed
from the first side. Then the combs are reversed and spun until
the second side is completely extracted. Finally, the combs are
reversed a second time and the remaining honey is removed. The
time required to throw honey from the combs depends on the density
and temperature of the honey. Watch the side of the tank to see
when the honey stops flowing from the combs.
Large radial extractors holding from six to eighty frames are
used in larger operations. Combs do not have to be reversed since
honey is thrown out of both sides at the same time. Combs are
arranged in the extractors like spokes in a wheel, with the top
bars on the outside.
After the honey is extracted, it contains air bubbles, pollen,
and bits of wax. Excessive pollen can be avoided by keeping brood
combs out of the honey supers. The honey should be strained through
several layers of cheesecloth or a single layer of nylon after
it is extracted from the combs. This procedure removes most impurities
and fragments of wax. Honey will absorb bad odors and flavors
rapidly if the materials that produce them are not strained from
the honey. Unless most or all of the wax has been removed during
extraction, the honey's flavor may be impaired during packing
since the honey is likely to be heated beyond the melting point
of wax before it is removed. After straining, keep the honey in
a settling tank for two to three days to allow most of the air
bubbles and small foreign particles to rise to the top. The resulting
foam should then be skimmed off before bottling. A honey gate
at the bottom of the tank is used for filling bottles or cans.
In large commercial operations, the honey normally flows from
the extractor(s) into a sump tank where most of the wax and impurities
are removed by a series of baffles.
