| What is freeze-drying . . .
. . and how does it work? |
It's probably an ancient desire to
preserve what is precious and beautiful --yet fleeting -- that led to
the practice of drying and preserving flowers. When we press a flower in
a book, or hang roses upside down to dry, we're using techniques going
back to ancient Egypt and Greece.
Later, artisans discovered that using
desiccants (drying agents like borax, silica gel or even sand) could
stop the flowers petals from shrinking while they dried, resulting in a
much more natural look. Both of these techniques are still widely used
today. Unfortunately, these techniques have a serious shortcoming --
they create a fragile end result. The flowers become quite delicate,
shattering or breaking easily. Nevertheless, these techniques are still
useful for certain special preservation situations when the right
technology is applied.
As in most things, the latest
technology has come to the rescue with a marvelous technique known as
freeze drying and treatments applied to the flowers prior to freezing
(water-based, non-hazardous, and biodegradable!) that produces an end
product that is amazingly like the fresh flower. The pretreatment helps
retain color, shatterproof and soften the freeze-dried flower. The
result is a beautiful, natural looking product that lasts many years
with proper care. The process requires a machine as
pictured at left, containing two
refrigeration units and one vacuum system. Ancillary freezers
supplement the system.
Freeze-drying is a process that retains the
color and texture of products. Unlike air drying, the product's
shape is maintained by virtue of it being frozen. While frozen,
the moisture is removed by way of vacuum, with all other
substances in the flower, such as pigment (color) and structural
parts (cells) immobilized.
The
design team at
Heavenly Petals of Maui
has undergone extensive training in both
the operation of the Hi-tech freeze drying machine as well as
the proper use of the pre and post treatments. A
process used only by the top professionals in this industry.
At
Heavenly Petals of Maui
your wedding flowers are preserved using the latest
freeze-drying techniques. As soon as we receive your bouquet,
we
photograph the flowers from several angles,
the bouquet is disassembled
and the individual flowers
are set out on a grid, and each individual flower is dipped or
sprayed with a water-based pre-treatment that contains a large
amount of cross-linked polymers. After drying, this allows the
flower to resist water re-absorption. The water-based polymers
also help eliminate petal-shedding and increase softness of the
dried petals. Antioxidants are added to reduce browning, as are
color-setting agents to reduce fading. Different flowers and
different colors require different pre-treatments -- this is why
the bouquet must be taken apart instead of just being dipped or
sprayed as a whole.
then apply a pre-treatment. When it is dry we place it in the
freeze dry machine where it is deep frozen. After twelve hours
the drying process starts, which takes up to fourteen days of
carefully regulating the freeze-dry machine.
When that is completed, a
post-treatment must be applied and
each
flower is wired, color enhanced (if needed) and post-treated to
seal the flowers. All the extras (pins, ribbons, pearls, etc.)
are placed in storage for use in creating your keepsake.
Heavenly Petals of Maui's design
team further preserves your freeze-dried wedding flowers by
mounting and then
framing them in a display of your choice.
Quite often, this
means putting the bouquet back together as it was when received
(we took pictures for this, remember?) Almost as often, brides
decide on a different presentation. They
will be behind an acrylic dome, in a glass globe, shadow box, or
jewelry box. We are able to customize your display with your
cherished memorabilia, such as photos, invitation, toasting
glasses, garter belt, and more.
Wherever in the world you live, you can always have Hawaii’s
spectacular flora as a remembrance of your island happiness.
This priceless keepsake will adorn your home for many years to
come!
Under normal conditions, your bouquet will
retain its beauty and natural splendor for many years, providing
that it is not exposed to direct sunlight.
Perfect Flower Preservation is the Rule with
our Freeze Dryers. Freeze drying creates preserved
flowers virtually without change in shape or color.
At
Heavenly Petals Of Maui
, we take special care in the processing and designing of your
floral masterpiece so that you can enjoy your special memories
