Abstract

PURPOSE:To produce dry flowers safely in a non-polluting way and inexpensively without damaging petals of a complicated natural flower, by dehydrating flowers arranged in a container containing hydrous salt of magnesium sulfate or magnesium sulfate sesquihydrate. CONSTITUTION:A natural flower 1 is allowed to stand in a container 2 containing anhydrous salt of magnesium sulfate or magnesium sulfate sesquihydrate 3 for 3-7 days at normal temperature and hydrated or the natural flower in the container 2 is heated and dehydrated by irradiation with a microwave by an electric oven 8 having 250MHz frequency and 500W power for 1-3min or by irradiation with the same amount of microwave by using an electric oven having different output. The flower is then preferably subjected to wax treatment 6 or coating treatment 7 to advantageously give dry flower. Magnesium sulfate is not so hard as conventional silica gel, petals and flesh of natural flower are not damaged, the price of magnesium sulfate is about 1/3 that of the silica gel and can be used as plant fertilizer after use.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for producing dried flowers.

[Prior Art] Conventionally, in order to produce dried flowers, silica gel granules or powder are placed in a container, fresh flowers are enclosed in the container, the container is sealed, and the container is left at room temperature for usually 3 to 7 days. (Leave at room temperature method). Water droplets remove moisture from fresh flowers due to the hygroscopic action of silica gel.

It is also known to use a microwave oven to accelerate the removal of moisture. In this case, without sealing the container, place it in a microwave oven with a frequency of 2450 M11z and an output of about 500 W, and heat it for 1 to 3 minutes (depending on the type of flower) (microwave method). It is better not to heat it to -degrees, but to divide it into two or three times, with a cooling period in between.

Dried flowers dried by either of the above two methods are immersed in a wax solution at 80 to 90°C and taken out. after that,
The shape is adjusted, dipped twice in coating liquid, and if necessary, the final product is completed.

[Problems to be Solved by the Invention] In both of the above two methods, fresh flowers are dried in a container containing silica gel. Commercially available silica gel is usually granular, coarse, and hard, whereas fresh flowers, which are the source of dried flowers, generally have weak and complicated petals.Therefore, this silica gel may damage the petals. was there.

This problem is caused by fine-grained silica gel, such as Gas Chroma! - This problem can be solved by using silica gel for graphics (60 to 200 mesh), but this is 5 to 6 times more expensive than normal silica gel. Furthermore, the only use for silica gel after use is to dispose of it as a nonflammable material.

The present invention was made to solve the above-mentioned problems, and provides a new method that can sufficiently remove moisture from fresh flowers without damaging their complex shapes, and is non-polluting even after they are used. The purpose is to

[Means for Solving the Problems] The present invention provides fresh flowers with anhydrous magnesium sulfate or 1.
It is characterized by dehydration in a container containing pentahydrate salt.

As the dehydration method, both the room temperature leaving method and the microwave oven method can be employed, as in the conventional method described above.

That is, in the case of the room temperature leaving method, fresh flowers in the container are left at room temperature for 3 to 7 days to dehydrate them.

In addition, in the case of the microwave oven method, the fresh flowers in the container are heated in a microwave oven with a frequency of 2450H1lz and an output of 500W.
Heat and dehydrate by applying microwave irradiation for 3 minutes or the same amount using a microwave oven with a different output.

A normal household microwave oven can be used. For example, a National (trademark) microwave oven model ME-410 with a switching knob set to "Niretsku (trademark) high" or a comparable one may be employed.

Further, dried flowers that have been dehydrated can be subjected to wax treatment and coating treatment as in the conventional method described above.

[Function] Anhydrous salt or 1.5-hydrate salt of magnesium sulfate has strong hygroscopicity and can adsorb moisture from fresh flowers. Silica gel is available in granular and powder forms, and is not very hard. Therefore, the complex shape of fresh flowers is not destroyed, and the soft flower flesh is not damaged.

Further, since magnesium sulfate is commercially available in various grades ranging from anhydrous salt to 1.5 hydrate salt, the moisture absorption and dehydration power can be adjusted by selecting an appropriate one according to the object. For example, heating and dehydration can be carried out in a microwave using high hydrate salt, which has a weak hygroscopicity, or low-temperature dehydration can be carried out using anhydrous salt, which has a strong hygroscopicity.

[Examples] Hereinafter, the present invention will be described by way of examples with reference to the accompanying drawings.

(Example 1) Orchid 1 (purple color) was placed in a glass cylindrical bottle 2 with a diameter of 80 mm and a depth of 100 mm. la in this bottle
It was filled with crystalline granules 3 of magnesium acid anhydride, sealed in M4 and left in a room temperature room for one week. Thereafter, when the orchid was taken out from container 2, dried flower 5 was obtained which retained the color and shape of a fresh flower.

Then, dry flowers 5 at 80-90℃ according to the standard method.
It was dipped in wax solution 6 and taken out. Furthermore, the shape was adjusted, dipped twice in solutions 1 to 7, and the final product was completed.

(Example 2) Orchid 1 (denp 7, purple) was placed in a glass cylindrical bottle 2 with a diameter of 80 mm and a depth of 100 mm. This bottle 2 is filled with crystalline granules 3 of anhydrous magnesium sulfate, and placed in a microwave oven 8 (National Microwave Oven ME-410 model) with a frequency of 2450 HIIZ and an output of 500 W without a lid.
I set it to "strong" and let it run for 1 minute and 50 seconds. Thereafter, when Orchid 1 was taken out from Container 2, Dried Flower 5 was obtained which retained the color and shape of a fresh flower.

Then, dry flowers 5 at 80-90℃ according to the standard method.
C was crushed in wax liquid 6 and taken out. The product was roughly shaped, dipped twice in Coating Solution 7, and worked on to complete the final product.

[Effects of the Invention] According to the present invention, crystalline granules of magnesium sulfate are not hard on silica gel, so they are less likely to damage soft petals and flower flesh.

Also, compared to silica gel, magnesium sulfate is 1/1 the price.
Since it is about 3, dry flowers can be produced at low cost.

Additionally, used magnesium sulfate can be used as a plant fertilizer, making it safer and less polluting than silica gel, which had no other use.
