The dried flowers retain their natural color, fragrance, and nutrients; however, their shape will shrink somewhat. This type of dried product is widely used because it only requires dried flowers, which are beautiful, retain nutrients, and can be used in many common ways, such as making rose tea, infusing roses into other products, making rose bath water, and making rose powder.

The freeze-drying chamber is completely sealed, ensuring that the fragrance is not diminished. Compared to other drying methods, freeze-drying preserves the natural scent of the product best.

For higher quality dried roses, specifically preserving their natural shape, freeze-drying is the best method. Freeze-drying, also known as sublimation drying, ensures that the shape is preserved, preventing shrinkage, deformation, and color loss, while also maintaining the nutritional value of the product. However, this method of drying roses to maintain high quality is typically used for decoration, gifts, or combining with other flowers to create unique items. Therefore, the product’s cost is relatively high, limiting its applications.

Freeze-drying is suitable for all types of flowers such as roses, jasmine, chrysanthemums, camellias, green tea leaves, rose buds, etc. It is also suitable for drying soft, high-value fruits like durian, avocado, kiwi, strawberries, or precious medicinal herbs such as cordyceps, shiitake mushrooms, termite mushrooms, and seafood mushrooms.
