Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention, when substituting and dehydrating fresh flowers with butanol and / or propanol to produce a dried fresh flower, does not cause white spots, that is, does not cause mottled whitening. The present invention relates to a method for obtaining a dried product of fresh flowers which retains the primary color.

[0002]

2. Description of the Related Art Conventionally, in order to produce a dried product of fresh flowers, a method of substituting and dehydrating fresh flowers with an organic solvent is a very advantageous method for obtaining a dried product of fresh flowers of original form and primary color, and it is generally carried out. Is the way. Then, this dried fresh flower was embedded in a transparent resin or resin-coated to obtain a plant specimen, an ornament, an ornament, or the like. In this method, as the organic solvent, tertiary butanol or low-temperature isopropanol is most suitable, and a considerable number of kinds of fresh flowers, for example, syringa, narcissus, primrose, violet, plum, peach, sakura, etc. The purpose was achieved only by dehydrating and then heating and drying. However, the method of substitution dehydration with the above-mentioned organic solvent is not sufficiently satisfactory in that point, because it may cause mottled whitening after drying.

Therefore, as a method of preventing this whitening,
A method of impregnating the surface of fresh flowers with cetanol is used. In the method of substitution dehydration with an organic solvent, it is often the case that bleaching occurs depending on the cultivar, but since it may appear depending on the individual, it is difficult to predict whether bleaching will occur. Therefore, it is usual to immerse fresh flowers that have undergone substitution dehydration in a solution of cetanol / butanol to prevent this. Fresh flowers that are bleached if not impregnated with cetanol include roses, pansies, azaleas, lilies, anemones, pot moms, tulips, and many other types.

According to the above method, the surface of fresh flowers is impregnated with cetanol to cause a slight clarification, and whitening is prevented. For the purpose of preventing whitening only, anything that is solid or liquid at room temperature and practically does not volatilize may be used, and various castor oils, waxes and other substances have been tried. From the point of view, and also from the point that it is not harmful at the time of post-processing and dissolves well in alcohol, cetanol is the best, so only cetanol is currently used.

However, in the known methods of impregnating with cetanol, some fresh flowers cannot prevent whitening because cetanol is not impregnated or is difficult to impregnate. The most typical of these are western orchids, with Cattleya at the top. Although there are not many types of fresh flowers, Western orchids occupy a large area in horticulture,
In many cases, the green leaves that accompany the flowers are whitened without being impregnated with cetanol, and there are fewer non-whitened leaves. In the case of leaf of anthracnose, black lily, etc., after substitution dehydration, a green color often remains even if it is immediately dried without being dipped in a solution of cetanol. It can be impregnated to leave a color, but many others do not leave a color when soaked in cetanol. That is, it is not impregnated with cetanol.

[0006]

In fresh flowers, even if distilling into molten butanol or butanol in which cetanol is dissolved after substitution dehydration with butanol and / or propanol, cetanol is not impregnated into the tissue. Include cattleyas, symbidiums, dentrobumes, and other flower foliage, and cetanol, which is normally easily impregnated but is difficult to impregnate depending on the time of growth, such as summer roses. .

According to the present invention, fresh flowers which are not impregnated or difficult to be impregnated with cetanol are easily impregnated with cetanol according to the above-mentioned known methods, without causing whitening. It is an object of the present invention to provide a method for obtaining a dried product of fresh flowers that retains its original shape and primary color.

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventor has found that fresh flowers substituting and dehydrated with butanol and / or propanol are converted into a xylol or amyl alcohol solution in which cetanol is dissolved. Immerse or once in xylol or amyl alcohol solution to replace butanol and / or propanol with xylol or amyl alcohol, and then soak it in a melt of cetanol or a xylol or amyl alcohol solution in which cetanol is dissolved. As a result, they found out that the surface of fresh flowers was easily impregnated with cetanol, and the present invention was completed.

That is, according to the present invention, fresh flowers are substituted and dehydrated with butanol and / or propanol, and then dipped in a xylol solution containing cetanol or an amyl alcohol solution containing cetanol to impregnate the fresh flowers with cetanol. After that, the method is a method for producing a dried product of fresh flowers, which comprises heating and drying. Further, the present invention, after substituting and dehydrating fresh flowers with butanol and / or propanol, soaking in a xylol or amyl alcohol solution, replacing butanol and / or propanol with xylol or amyl alcohol, a melt of cetanol, A method for producing fresh flowers, which comprises immersing fresh flowers in a xylol solution in which cetanol is dissolved or in an amyl alcohol solution in which cetanol is dissolved to impregnate fresh flowers, and then heating and drying.

In the present invention, not only the flower portion of the fresh flower but also the green leaves attached to the flower are called fresh flowers. It is a very commonly practiced method to substitute and dehydrate fresh flowers with butanol and / or propanol to obtain primary color dried flowers for embedding transparent resin or coating resin. At this time, tert-butanol is the most gentle and suitable for fresh flowers, so tert-butanol is usually used, but tert-butanol has a melting point of 2
Since it is relatively high at around 5 ° C, fresh flowers that cannot retain their shape unless they are at low temperatures, such as those that tend to shrink during dehydration, such as Caryophyllum japonica, or those that do not form when the core is disturbed, such as passionflower For those that need to be kept in shape, use low temperature isopropanol.

[0012] In addition, dehydration at 13 ° C or lower, preferably at 10 ° C or lower, such as shrimp, ginkgo biloba, and lily of the valley, which undergo blackening due to enzymatic activity when dehydrated at 25 ° C. Work is advisable, in which case tertiary butanol with 10 to 20% isopropanol is used.

When fresh flowers are immersed in the above butanol and / or propanol for displacement dehydration and then immersed in a xylol solution in which cetanol is dissolved or an amyl alcohol solution in which cetanol is dissolved, butanol and / or propanol are replaced, and xylol is replaced. Alternatively, cetanol is impregnated into fresh flowers together with amyl alcohol.

At this time, as the xylol or amyl alcohol solution in which cetanol is dissolved, a solution in which 30 to 70% of cetanol is added to xylol or amyl alcohol and heated and dissolved at 40 to 60 ° C. is used. When dipping fresh flowers that have been substituted and dehydrated with butanol and / or propanol into this, 40-60
It is preferable to carry out the treatment at a temperature of ℃. In this case, when the proportion of cetanol is small, it can be carried out at room temperature. The immersion time varies depending on the type of fresh flowers, and there are cases where it is completed in a short time of about 1 hour, and cases where one day and night are required. Fresh flowers impregnated with cetanol as described above are dried by heating to give dried products. Although heat drying can be performed by any method, it is preferable to perform drying with hot air at about 60 ° C.

By the above-mentioned method, fresh flowers can be impregnated with cetanol. However, since the amount of cetanol impregnated is relatively small, it is necessary to increase the amount of cetanol impregnated, especially in the green leaves. Immersing the dehydrated fresh flowers substituted with butanol and / or propanol in a xylol or amyl alcohol solution,
It is preferred to replace butanol and / or propanol with xylol or amyl alcohol.
The dipping treatment in the xylol or amyl alcohol solution may be performed at room temperature.

The fresh flowers treated in this manner are dipped in a melt of cetanol, a xylol solution in which cetanol is dissolved, or an amyl alcohol solution in which cetanol is dissolved to impregnate the fresh flowers with cetanol. At this time, as the xylol or amyl alcohol solution in which cetanol was dissolved, 40 to 50% of cetanol was added to xylol or amyl alcohol so that
It is preferable to use the one that is heated and melted at ℃. Although it is necessary to use a melt of cetanol for fresh flowers that are extremely susceptible to whitening, some xylol or amyl alcohol solutions containing 50-70% cetanol are sufficient, so depending on the type of fresh flowers. Select and use. Fresh flowers impregnated with cetanol as described above are dried by heating to give dried products. This drying can be performed by any method as described above, and is preferably performed with hot air at about 60 ° C.
