Abstract
Description
Technical Field
[0001] This invention relates to the field of plant processing and preservation technology, specifically to a method for preparing dried tropical orchid flowers and their three-dimensional display. Background Technology
[0002] Phalaenopsis, a plant belonging to the genus Phalaenopsis in the family Orchidaceae, is known as the "Queen of Orchids" due to its unique flower shape, which resembles a butterfly in flight. It boasts numerous varieties with vibrant colors, including red, purple, pink, yellow, green, white, and multi-colored blooms. It can be grown as a potted plant, cut flower, or dried flower.
[0003] Existing single physical color preservation methods, such as high-temperature decompression color preservation, low-temperature decompression color preservation, and microwave drying color preservation, can maintain the bright colors of plant materials to a certain extent. However, they have high requirements for equipment and require strict control of parameters such as temperature, humidity, and pressure during operation. For flowers like Phalaenopsis orchids that are sensitive to temperature changes, physical color preservation methods cannot completely avoid fading problems.
[0004] Furthermore, existing dried flower products are mostly simply displayed in frames or open containers, which are prone to dust accumulation and moisture absorption, and the viewing methods are monotonous, lacking artistic enhancement effects. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a method for preparing dried tropical orchid flowers and their three-dimensional display, which can effectively improve the preservation and display effects of dried flowers.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A method for preparing dried tropical orchid flowers. The method for preparing dried flowers specifically includes the following steps: S1-1. Select Phalaenopsis orchid flowers free from pests and diseases, cut them off along with the flower stalks, wash and dry them to obtain the flower materials for use. S1-2. Immerse the prepared flower materials in the setting solution, then remove them to obtain pre-treated flower materials; The setting solution is prepared by mixing solution A and solution B in a volume ratio of 1:2-3. The specific components of solution A and solution B are as follows: Solution A is composed of the following raw materials in the following volume parts: 16-20 parts polyethylene glycol, 20-30 parts anhydrous ethanol, and 5-7 parts caprylic triglyceride. Solution B is composed of the following raw materials by volume: 7-10 parts glycerol and 0.5-1 part sunflower extract; S1-3. Embed the pretreated floral materials in a composite desiccant, seal and stand at room temperature for 50-70 hours, and perform three intermittent drying processes to obtain dried floral materials. S1-4. Place the dried flowers in a sealed container in a cool, dry place to obtain dried Phalaenopsis orchid flowers.
[0007] Preferably, the spare flowers in step S1-1 should be Phalaenopsis orchids with about 80%-90% full bloom, with stems 5-10cm long.
[0008] Preferably, the three intermittent drying steps S1-3 are as follows: microwave drying at 70-90% for 30-50 seconds, then removing the product to complete the first drying; microwave drying at 40-60% for 30-50 seconds, then placing the product in a vacuum environment at -10-0℃ for 20-30 seconds, then removing the product to complete the second drying; microwave drying at 70-90% for 30-50 seconds, then removing the product and allowing it to return to room temperature to complete the third drying. The interval between the first and second drying is 10 seconds, and the interval between the second and third drying is 16-20 seconds.
[0009] Preferably, the cooling rate in the vacuum environment is 4°C / min.
[0010] Preferably, the composite desiccant in steps S1-3 is composed of color-changing silica gel, molecular sieve, and sodium chloride in a volume ratio of 5-7:2-4:1.
[0011] A method for displaying dried flowers in three-dimensional art includes the following steps: S2-1. Display container preparation: Select a sealed container made of transparent glass and arrange light strips; S2-2, Fixing and Assembly: Place and fix the dried Phalaenopsis orchid flowers in the spare display container, and then vacuum-seal the container; S2-3, Activation and Viewing: Power on for viewing, three-dimensional display.
[0012] Preferably, in step S2-1, the light strip is wrapped around the inner wall of the container near the bottom or lower middle part.
[0013] Preferably, the method of fixing the dried Phalaenopsis orchid flowers in step S2-2 is to fix the dried Phalaenopsis orchid flowers in a sealed container with transparent gardening wire or hot melt glue.
[0014] Preferably, the vacuuming in step S2-2 requires the pressure inside the container to reach -0.05MPa to -0.08MPa.
[0015] This invention provides a method for preparing dried tropical orchid flowers and their three-dimensional display, which has the following advantages compared with the prior art: By combining chemical and physical methods such as "pretreatment with setting liquid" and "three-step drying with composite desiccant", the technical problems of easy deformation and fading during the drying process of tropical orchids are effectively solved, and the finished product has a full shape and a color close to that of fresh orchids.
[0016] During the drying process of pre-treated flowers, three intermittent drying processes are used, with a low-temperature heating and vacuum freezing treatment interspersed between two high-temperature heating processes. This approach maintains the dryness of the petals while increasing the drying speed and preserving their color, and also reduces the shrinkage rate of the flowers, thereby comprehensively enhancing the overall value of the dried flowers.
[0017] This solution creates a uniform and soft light field inside the vacuum jar using built-in low-light illumination equipment, which greatly enhances the texture and artistic expression of dried flowers. Furthermore, the vacuum environment isolates oxygen and moisture, significantly slowing down the oxidation and deterioration process of dried flowers, allowing them to maintain their excellent condition for several years and become decorative art pieces.

Microwave drying was performed in a Midea microwave oven (700W).
[0021] 1. Preparation of Solution A: Solution A1 is composed of the following raw materials in the following volume parts: 16 parts polyethylene glycol, 20 parts anhydrous ethanol, and 5 parts caprylic triglyceride.

[0023] 3. Preparation of setting solution: The setting solution is prepared by mixing solution A and solution B at a volume ratio of 1:2-3. Based on the different compositions and proportions of solutions A and B, five sets of setting solutions were combined, and their specific compositions and proportions are shown in Table 1: Table 1 Example 1: The shaping of Phalaenopsis orchid flowers: S1. Select Phalaenopsis orchid flowers that are about 85%-89% in full bloom and free from pests and diseases. Cut them off along with the flower stalks, leaving an 8cm long stalk. Wash them with clean water and drain them to obtain the flower materials for use. S2. Immerse the prepared flower materials in setting solution A for 8 seconds, then remove them to obtain pre-treated flower materials.
[0024] Example 2: This embodiment refers to the setting method of Embodiment 1, except that setting liquid A is replaced with setting liquid B, and all other steps are the same as in Embodiment 1.
[0025] Example 3: This embodiment refers to the setting method of Embodiment 1, except that setting liquid A is replaced with setting liquid C, and all other steps are the same as in Embodiment 1.
[0026] Comparative example: This comparative example has four experimental groups, and the only difference between the experimental groups is the choice of the setting solution. The other steps are the same as in Example 1, as shown in Table 2: Table 2 Detection: Immerse the prepared floral materials in the setting solution for 5-10 seconds, remove, air dry, and observe the condition of the flowers, as detailed in Table 3 below.

Further observation of the floral materials in experimental groups 1-4 reveals that the flowers in experimental group 1 show obvious discoloration. Figure 1 As shown in d, slight discoloration occurred at the edges, and slight wrinkles appeared after drying; the flowers in experimental group 2 showed the same condition as those in experimental group 1, and those in experimental group 3 ( Figure 1 (as shown in f) and experimental group 4 ( Figure 1 (As shown in g) The flower color is well maintained, but the flower shape is deformed due to the petals being too soft. Overall, the pre-treated flowers in Examples 1-3 are the best.
[0027] Example 4: Drying of pre-treated floral materials: S1. First, lay a 2cm thick layer of composite desiccant (composed of color-changing silica gel, molecular sieve, and sodium chloride in a volume ratio of 6:3:1) at the bottom of the sealed box. Place the pre-treated flower material from Example 1 with the flowers facing upwards in the sealed box. Slowly fill the box with the composite desiccant using a teaspoon, starting from the side of the pre-treated flower material to support its three-dimensional structure. Finally, gently cover the entire pre-treated flower material. Seal and let stand at room temperature for 60 hours. Then, microwave at 70% power for 30 seconds. Remove the flower material to complete the first drying. After a 10-second interval, microwave at 40% power for 30 seconds. Place the flower material in a vacuum environment and cool it down to -8℃ at a rate of 4℃ / min. Let it stand for 20 seconds to complete the second drying. After a 15-second interval, microwave at 70% power for 30 seconds. Remove the flower material and allow it to return to room temperature to complete the third drying, thus obtaining the dried flower material. S2. Seal the sealed box containing the dried flowers tightly and place it in a cool, dry place for 60 hours to obtain dried Phalaenopsis orchid flowers.
[0028] Example 5: Drying of pre-treated floral materials: S1. First, lay a 2cm thick layer of composite desiccant (composed of color-changing silica gel, molecular sieve, and sodium chloride in a volume ratio of 6:3:1) at the bottom of the sealed box. Place the pre-treated flower material from Example 1 with the flowers facing upwards in the sealed box. Slowly fill the box with the composite desiccant using a teaspoon, starting from the side of the pre-treated flower material to support its three-dimensional structure. Finally, gently cover the entire pre-treated flower material. Seal and let stand at room temperature for 60 hours. Then, microwave at 70% power for 40 seconds. Remove the flower material to complete the first drying. After a 10-second interval, microwave at 40% power for 40 seconds. Place the flower material in a vacuum environment and cool it down to -8℃ at a rate of 4℃ / min. Let it stand for 25 seconds to complete the second drying. After a 16-second interval, microwave at 70% power for 40 seconds. Remove the flower material and allow it to return to room temperature to complete the third drying. The dried flower material is then obtained. S2. Seal the sealed box containing the dried flowers tightly and place it in a cool, dry place for 60 hours to obtain dried Phalaenopsis orchid flowers.
[0029] Example 6: Drying of pre-treated floral materials: S1. First, lay a 3cm thick layer of composite desiccant (composed of color-changing silica gel, molecular sieve, and sodium chloride in a volume ratio of 6:3:1) at the bottom of the sealed box. Place the pre-treated flower material from Example 1 with the flowers facing upwards in the sealed box. Slowly fill the box with the composite desiccant using a teaspoon, starting from the side of the pre-treated flower material to support its three-dimensional structure. Finally, gently cover the entire pre-treated flower material. Seal and let stand at room temperature for 60 hours. Then, microwave at 80% power for 50 seconds. Remove the flower material to complete the first drying. After a 10-second interval, microwave at 50% power for 50 seconds. Place the flower material in a vacuum environment and cool it down to -8℃ at a rate of 4℃ / min. Let it stand for 30 seconds to complete the second drying. After an 18-second interval, microwave at 80% power for 50 seconds. Remove the flower material and allow it to return to room temperature to complete the third drying, thus obtaining the dried flower material. S2. Seal the sealed box containing the dried flowers tightly and place it in a cool, dry place for 60 hours to obtain dried Phalaenopsis orchid flowers.
[0030] Comparative example: This comparative example follows the preparation steps of Example 2, only adjusting the specific operations of the first drying, second drying, and third drying, as shown in Table 4: Table 4 Detection: The pre-treated floral materials were placed in a microwave oven and dried according to the procedures in Example 2 and the comparative example. After drying, the materials were observed, weighed, and measured to calculate their water loss rate and shrinkage rate. Water loss rate = (mass before drying - mass after drying) / mass before drying * 100% Shrinkage rate = (diameter before drying - diameter after drying) / diameter before drying * 100% The observation and calculation results are shown in Table 5 and Figure 2 As shown: Table 5 From the table above and Figure 2 As shown in Examples 4-6, Example 5 ( Figure 2 The drying effect was best in group b). Observe the experimental results of experimental groups 1-5. Experimental group 2 (shown in Figure b) Figure 2 The shrinkage rate of experimental group 3 (as shown in Figure e) was relatively small, but its drying degree was poor. That is, even if reducing the microwave power during the first drying could maintain a small shrinkage rate of the flowers during drying, it could not dry them completely; Figure 2(As shown in Figure g) Without the vacuum freezing step, the water loss rate was significantly reduced, resulting in poor dryness, and its shrinkage rate was significantly increased compared to Example 5; the vacuum freezing time of Experimental Group 5 was increased, which was obvious, as... Figure 2 As shown in Figure h, the texture becomes brittle, which will likely reduce the integrity of the dried flowers, and the shrinkage rate of the flowers will increase significantly.
[0031] Example 3: A method for displaying dried flowers in three-dimensional art includes the following steps: S1. Display container preparation: Select a sealed container made of transparent glass and wrap the light strip around the inner wall of the container near the bottom or lower middle part; S2. Fixing and assembly: Place the dried Phalaenopsis orchid flowers prepared in Example 5 into the spare display container, fix them to the cork in the center of the sealed container with hot melt glue, and use a small vacuum pump to extract the air from the sealed container to make its interior reach a negative pressure of -0.07MPa. S3. Activation and Viewing: When viewing, the power is turned on, and the light shines evenly on the dried flowers through the vacuum environment to achieve a three-dimensional display effect.
