FFPs - Frequently Faced Problems |
|
When Honey is dried conventionally, the HMF (Hydro
Methyle Furfural) content in the Honey often goes up to 40% due
to over heating. Honey with high moisture content is not acceptable
to the Pharmaceutical Industry, where the Honey finds maximum usage.
Internationally, the demand for Mono-flora
Honey (Honey produced from single type of flower) is very high especially
due to it's application in the Pharmaceutical Industry. It is required
with a moisture content of 19% and Hydro Methyle Furfural (HMF)
content 25%. If the honey has a moisture content higher than specified,
it has to be dried to achieve a moisture content of 19%.

| General
Recommendation : |
Honey is required with a moisture content of 19% and
Hydro Methyle Furfural (HMF) content 25%. If the honey has a moisture
content higher than specified, it has to be dried to achieve a moisture
content of 19%. It is recommended that the honey is dried at 35°C
to a moisture content of 19%.

When the Airgineers at Bry-Air
were contacted to solve the problem of over heating, they studied
the conventional and current method of drying prior to recommending
the solution.
Here is what they
learnt:
Honey is mainly of three types
Mono-Flora Honey - Honey produced from single type of flower
Poly Flora Honey - Produced from various types of flowers
Forest Honey - Produced from Forest Flower
Raw honey after being collected from the farmer by the processor was
cleansed of all unwanted material, viz., dead bees, limbs, and parts
of beehives by filtration. Then, it was dried to achieve a moisture
content of 19%.
Conventional Method:
The honey is kept inside a drum and continuously stirred.
Hot water is circulated through a jacket surrounding the drum filled
with honey. The Honey, thus, was heated indirectly to a temperature
of 65°C to bring down the moisture content to 19% from the existing
25-30%.The problem was that the HMF content goes up to over 40% due
to heating over 35°C.
Bry-Air Recommendation:
The Airgineers at Bry-Air recommended that honey be
spread on trays to a maximum thickness of 4 inch inside an enclosed
room. Dehumidified air is then circulated inside the room, which is
maintained at temperature of 35°C. The temperature being maintained
by an airconditioner. This allows reduction of moisture content without
raising the HMF content. It was also suggested to pack the dried honey
into the containers inside the dehumidified room, so that the dried
honey does not regain moisture.
