What is Floral Freeze Drying (Lyophilization) ?
The basic principle of floral freeze drying (Lyophilization) is the removal of water from frozen botanicals as water vapor, and collection of this water vapor as ice in a condenser. With the botanicals solidly frozen during the process, and under a deep vacuum, shrinkage is eliminated or minimized, and near perfect preservation will result. The process requires the flowers to be frozen and then gradually the temperature is raised to stimulate sublimation (ice crystals changing directly to water vapor). Over a period of days all the water from the botanicals will sublimate and go into a condensation chamber. The water vapor turns back into ice in this very cold (-40° F or lower) condensation chamber. Defrosting the condensation chamber removes moisture from the freeze drying (Lyophilization) system. When ice quits forming in the condenser the load is dry. Often the only requirements for long term storage of freeze dried materials is the prevention of moisture re-entering the product.
When the Freeze Dried Flower Industry began in 1988, the flowers were fragile, shattered easily, and had a tendency to change color. These problems have all been addressed through chemistry. The pre- and post- treating chemicals used today meet the needs for color stabilization, durability, and longevity in freeze dried flowers.
Floral Preservation Is An Art Form: For this reason we will need to get your flowers within 2-3 days of the event to get the highest standard of preservation. While most flowers freeze dry well, some flowers may be more challenging. We will notify you if we are unable to freeze dry them successfully.

Flower Preparation:
It is best to get your flowers to us within 2 to 3 days after the day of the event.
|
Place flowers (if in vase or oasis make sure there is water in the container then place in the bag filled with air) in water in the refrigerator. |
|
Trim stem about 1/2 inch if possible for flowers to re-hydrate. |
|
Make sure there are no fruits and vegetables around flowers when placed into refrigerator. |
|
Do not place in freezer. |
|
You may deliver the flowers to Floral Preservation by Event Designs in Zebulon, or at our new drop location in Roswell. You may also call us for courier service 770-567-0642. Using the Roswell drop or courier service, will incur a delivery charge. |
