ABSTRACT:
Traditionally flowers are dried for decorative purposes by being left immersed in a bed of fine sand. The sand holds the flower in a constant conformation and prevents damage such as the crinkling of petals during dehydration. The invention provides a process in which the labor-intensive operation of covering the flower manually with the sand is avoided. The sand is fluidized by means of a gentle current of air rising therethrough, enabling the flower to be simply immersed in the sand without damage or change in conformation. Fluidization is stopped, and the flower is instantly locked in place by the sand ready for dehydration. After dehydration, the flower can be removed from the sand easily by re-fluidizing the sand.
