Abstract

PROBLEM TO BE SOLVED: To realize the easy and short time formation of a vegetable specimen under the condition that the color intrinsic to the vegetable is utilized by a method wherein microwaves are applied to the state that the outer surface of a raw sample, hygroscopic porous of flexible sheets and hygroscopic particulates are stuck fast to one another. SOLUTION: As a microwave generating device, a domestic microwave oven is utilized conveniently. The water in a raw sample applied with microwaves immediately is heated up to high temperature and turned into vapor. The vapor generated at that time is passed through porous flexible sheets and absorbed instantly by silica gels 5. The maximum point is the instant absorption of the generated vapor by hygroscopic particulates for quick separation of the raw sample from the water vapor. The water vapor not absorbed by the silica gels 5 on the outer periphery of the porous flexible sheets must be absorbed by the hydroscopic porous substance in the outer periphery. Thus, a vegetable specimen having a bright color can be manufactured in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for producing a colorful and beautiful plant specimen in a short time by using a granular silica gel and a microwave of a microwave oven by utilizing the primary colors of the plant. The present invention relates to an inexpensive and easy method for quickly drying and preserving a plant or the like so that a plant specimen can preserve a beautiful color inherent in a possessed plant for a long time as a plant specimen that is hardly faded. In addition, the present invention relates to a method for rapidly drying plants and the like in which dried plants can be used for tea and the like.

[0002]

BACKGROUND ART As a method for producing a plant specimen, a method for producing a pressed flower includes a weight processing method, an indirect flower gel dry ring method,
There are direct flower gel drying method, ceramic method, shallow light using far infrared rays, etc., but basically, water absorbing members are placed on the upper and lower sides or on any one of the upper and lower sides to dry the plants. Recently, a method for producing pressed flowers using a typical indirect flower gel drying method among the methods using dielectric heating of a microwave oven will be described.

A method for producing pressed flowers by indirect flower gel drying. A pressed flower sponge is placed on the pressed flower dried sheet, and further a pressed flower rayon paper is placed. Arrange fresh flowers that have been subjected to pretreatment to make them easier to press. Rayon paper for pressed cottage, sponge for pressed flower,
Stack the dried sheets for pressed flowers in this order. Put into a vinyl sheet for pressed flowers, set between them, sandwich between two pressed hills for pressed flowers, and fasten with Velcro. Bleed the air in the vinyl and close the zipper at the mouth of the pressed flower vinyl sheet. After 1-2 days, replace the dry sheet for pressed flowers. After 3 to 6 days, if the fresh flowers are dry, the pressed flowers are completed. Unless the dry sheet is frequently replaced, colorful pressed flowers cannot be made.

Further, Japanese Patent Application Laid-Open No. Hei 4-49202 discloses a method for producing pressed flowers by irradiating microwaves to produce pressed flowers. That is, a pair of laminated plates having a porous buffering agent interposed between the ceramic plate and the water-absorbing sheet are provided, and the flowers are pressed and sandwiched on the water-absorbing sheet surface side of each of the laminated plates, and in this state A method for producing a pressed flower, characterized in that the pressed flower is dried by dielectric heating. The biggest feature of this method is disclosed in Japanese Patent Laid-Open
As described on page 2, right upper column, line 14 to lower left column, line 1, page 9202, a ceramic plate heated by dielectric heating emits far-infrared rays. The moisture contained in the flowers is evenly heated by dielectric heating using high frequency or microwave to evaporate the moisture. However, in this method, it takes time until the ceramic plate is heated, and since far-infrared rays are heat rays, it takes time to heat and evaporate the contained moisture, and the color of the flower tends to be discolored. In particular, when the amount of flowers increases, the amount of water inevitably increases, and the porous buffering agent is a sponge or the like for the purpose of buffering only. Evaporation of the water slows down, and the tendency to discoloration increases, resulting in a poorly pressed flower. The present inventor has confirmed that this method of combining a ceramic and a microwave oven is not suitable for producing beautiful dried flowers such as pressed flowers.

Table 1 shows the results of a comparison between the method of the present invention, a method combining a ceramic and a range, and a method using a push plate.

[Table 1] As is clear from Table 1, the method of the present invention can quickly dry a plant that is a raw sample.
It has been confirmed that the color is vivid and, for example, when a sample is prepared, the time required for the color to fade is much longer than that of the conventional one. When the plant specimen is made by the pressed flower drying sheet method as described above, it takes about 1 to 6 days, and the pressed infrared ray utilization method uses 7 to 10 hours,
The method using a combination of a range for pressed flowers and ceramic requires a production time of about 1 minute 30 seconds to 4 minutes.

[0006] Moisture, oxygen, and ultraviolet rays are causes of deterioration and fading of plant specimens. In the conventional method of preserving plant specimens, measures are taken to prevent moisture and oxygen by shutting off the flow of air. No UV protection measures have been taken. For this reason, if a plant specimen is displayed in a bright room, fading will begin in about six months for heat film, about one year for Japanese paper and pressed flower film, and about five years for a sealed frame, depending on the type of plant. .

[0007] In the case of the conventional holding method in which the frame is held in a frame, silica gel is fixed to the back side of the frame back plate with an adhesive tape or the like, and a double aluminum foil having the same size as the frame back plate is stuck thereon. How to stick, put the adhesive around the inside of the edge of the backing board, and put it out a lot without leaving a gap, put an aluminum foil on top of this, and use a straw or cloth etc. to attach it to the backing board. Adhere so that no air remains between the aluminum foils. Next, two sheets of nonwoven fabric or cooking paper having the same size as the back plate are stacked on the front side of the back plate, and only the edges are stuck with an adhesive. Place the plant specimen in the desired position using tweezers on the back plate that has been prepared as described above.
After placing the plant specimen, apply adhesive so that there is no gap between the edges of the cooking paper on which the plant specimen is arranged, and place the glass plate on the plant specimen on the back plate. Finally, when putting the edges of the above items on the forehead with aluminum tape, stick them around the sides, taking care not to see the tape from the front. In addition, there is a method of coating the surface of the glass with an ultraviolet ray cutting agent, combining aluminum foil and a vacuum pack, or using an infrared shielding heat film, but the tools and chemicals used in these manufacturing methods are: In many cases, it is not commercially available, is difficult to obtain, and is expensive.

[0008] Degradation and fading can be considerably prevented if the plant specimen is sealed with silica gel and stored in a dark place. However, it is only necessary to keep the plant specimen. In the case of observing and enjoying while watching, if the color fades in one or two years after the production and display, the value as a specimen is reduced by half.

[0009] Even a technique devised so as not to fade easily,
Although there is a method of using a material such as a special resin solution or a method of creating and maintaining a vacuum state, these materials are generally difficult to obtain or expensive in many cases.

[0010]

Generally, it is said that in order to produce a colorful plant specimen, it is necessary to absorb and dry the water of the plant as quickly as possible. The present invention relates to a method for drying a raw sample in a short time to produce a pressed flower or a specimen having a beautiful color, and further relates to a method for producing a tea or herb having a beautiful natural color and aroma. In addition, a new method for quickly drying a new raw sample that emits microwaves that resonate only water molecules and heats it to evaporate the generated water as quickly as possible and retain the color and scent of the original raw sample Develop. In the case of plant specimen manufacturing methods such as the dried sheet method for pressed flowers, the method of using far-infrared rays for pressed flowers, and the ceramic method for pressed flowers, it takes a long time to manufacture the plants. In the case of inclusion, silica gel may adhere to the plant, the plant may be distorted, and if the amount of the plant is large, moisture may remain and discoloration may occur. Moreover, tools used in these production methods are pressed flowers. Because they are sold exclusively, they are often expensive or difficult to obtain.

[0011] In order to keep the plant specimens bright and colorful for a long time, to prevent exposure to the outside air and to prevent ultraviolet rays,
By applying a UV cut effect, the fading of the plant specimen is delayed. The present inventor, in view of the problems of the conventional technology, the technology devised to solve these problems, utilizing the original color of the plant, a method for producing a plant specimen that can be made easily and in a short time,
The method of preserving the freshly prepared colorful plant specimens so that they can easily be kept in beautiful colors for a long period of time should be based on the preservation method using familiar materials and garbage, and use easily available commercially available products. And keep production costs low,
An object of the present invention is to provide a method of manufacturing and preserving a plant specimen that is most suitable for use in educational sites and the like and for dissemination.

[0012]

According to the present invention, a raw sample is covered with a hygroscopic porous flexible sheet on the outer surface, and the outer periphery of the sheet is formed of an amount of hygroscopic granules capable of absorbing all the moisture contained in the raw sample. It has been found that it is possible to quickly dry by irradiating with microwaves by enclosing the outer surface of the raw sample in close contact with the hygroscopic porous flexible sheet and the hygroscopic granular material. Covering the outer surface of the hygroscopic granule with a porous hygroscopic body, such as corrugated cardboard, acts to further release the moisture absorbed by the hygroscopic granule and / or the powder to the outside. The dried sample thus obtained can be used for drinking in the case of tea or herbs,
It can also be used as a specimen. In order to prevent fading of the dried body, a UV-cut film, a means for cutting off oxygen, or a desiccant may be used in combination.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to produce a colorful plant specimen in a short time, it is important how quickly moisture contained in a raw sample is taken out and dried. For this reason, it is considered that the water-absorbing member is optimally a pressed flower silica gel sheet or a pressed flower dried sheet, but it is often difficult to obtain these water-absorbing members. It takes about one to six days to manufacture. Although there is a method using a microwave oven, the plants may be deformed or twisted. As a result of comprehensively examining these problems, the raw sample was wrapped and protected with a flexible porous sheet, and granular silica gel, which was fully used as a drying agent for food in the vicinity, was used as a water-absorbing member around it. I found that it was good to use microwaves in the microwave.

Generally, in order to widely spread decorative plant specimens, it is easy to obtain even in the lower grades of elementary school children, and it is easily available on the market so that it can be inexpensive. I think it is important to select and use clothing and drugs. The tools, the porous flexible sheet, the hygroscopic granules, and the like used in the present invention are all commercially available, and thus are easily available. As a porous flexible sheet,
Paper such as Japanese paper, tissue paper, newsprint, and cloth such as cotton can be used. As the hygroscopic granular material, granular silica gel is typically used. The granular silica gel may be commercially available for storing dried flowers, or may be a collection of silica gel encapsulated for storing food such as confectionery. Examples of the hygroscopic porous body include cork, corrugated cardboard, perforated corrugated cardboard, thick paper, and the like. The cardboard can be made into a box shape and a desiccant can be put in it. Examples of the desiccant include calcium chloride, calcium oxide (quick lime), silica gel, zeolite, and the like, and a water-absorbing polymer can also be used. In addition, a UV cut transparent film commercially available as office or stationery supplies, a UV cut acrylic resin solution for handicraft supplies, silicon paste, or the like can be used in combination.

As a microwave generator used in the present invention, a commercially available microwave oven for home use is easily used. In order to industrially produce a large amount of dried material, a large microwave generator is used. The water in the raw sample that has been subjected to microwaves quickly becomes hot and changes to water vapor. At that time, the generated steam is instantaneously absorbed by the silica gel through the porous flexible sheet. The most important point of the present invention is that the generated water vapor is instantaneously absorbed by the hygroscopic granules, and the raw sample and the water vapor are quickly separated. Therefore,
Water from the raw sample must not condense and come into contact with the raw sample. The generated water vapor is immediately absorbed so that the water from the raw sample does not condense and come into contact with the raw sample again. The water vapor that cannot be absorbed by the silica gel on the outer periphery of the porous flexible sheet needs to be further absorbed by the hygroscopic porous body on the outer periphery. In order to check whether silica gel has absorbed moisture, it is convenient to mix silica gel with cobalt chloride added to transparent silica gel. Silica gel to which cobalt chloride has been added exhibits a blue color when dried, but turns pink when it contains moisture, so that it can be seen at a glance whether or not it has absorbed moisture. Paper and cork are suitable as the moisture-absorbing porous body, and those obtained by stacking half-paper, corrugated cardboard, cork board, and the like, and desirably holding a desiccant on them are desirable. In addition, the moisture-absorbing porous body also serves as a cushion when the weight is placed from above. If it is expected that a large amount of water vapor will be generated, the cardboard box should be box-shaped and silica gel or calcium chloride should be put in it. When many raw samples are used, as shown in FIG. 3, a cardboard box 30 having small holes 31 filled with a desiccant 32 can be used as the moisture-absorbing porous body. If the hygroscopic porous body does not work well, hot water and steam are trapped, and the color of the dried sample becomes worse, and discoloration and deterioration occur. The embodiments of the present invention are summarized as follows. (1) The outer surface of the raw sample is covered with a hygroscopic porous flexible sheet, and the outer periphery of the sheet is surrounded by hygroscopic granules of an amount capable of absorbing all the moisture contained in the raw sample.

EXAMPLES First, the method of rapid drying actually performed is specifically described, but the present invention is not limited thereto. The outline will be described with reference to FIGS. A large heat-resistant container 1 to be put in a microwave oven is prepared, and two corrugated cardboard or a cork plate 3 having a thickness of about 2 mm are laid in this container. On top of that, a piece of paper or kitchen paper 4
With corrugated cardboard or cork board 3 of about 2 mm thickness
Lay it on. Silica gel 5 is put on half paper or kitchen paper 4 until it reaches a height of about 0.6 to 1.5 cm, and several sheets of tissue paper 6 are laid on top of each other. On the Tepsch paper, the plants 7 of the raw samples which have been subjected to the pretreatment for removing excess stems and leaves, washed and shaped are arranged so as not to overlap. Lay several tissue papers 6 on the raw sample plant 7 in the reverse order,
Next, silica gel 5 is inserted until the height reaches about 0.6 to 1.5 cm, and a half paper or kitchen paper 4 is laid thereon, and two corrugated cardboard boards 3 each having a thickness of about 2 mm are laid. . Then, the lid 2 of the container is turned upside down and the lid is fixed with a rubber band or the weight is weighed with a thick book or the like so as to apply pressure to the plant which is a raw sample lightly, and the container is heated in a commercially available microwave oven.

Example 1 Pleurotus terrestris (scientific name: Trillium k
(Amtschaticum Pall) is prepared as a specimen by a quick drying method. 2 in size
A 0 W x 14.5 cm heat resistant container was used, and a 600 W commercial home microwave oven was used. The amount of silica gel used is divided into upper and lower parts of the plant of the raw sample, but as a result of thinking and error, the total amount of silica gel is 250 g, considering the amount of silica gel that can cover the plant that is the raw sample.
The above proved to be good. The heating time of the microwave oven is 60 seconds when the total weight of the silica gel is 250 g, and 50 seconds when the total weight of the silica gel is 350 g, regardless of the size and shape of the silica gel particles. A specimen was obtained. In addition, the total weight of silica gel
Experiments were carried out for 400 g and 450 g. In both cases, quick drying was performed in 50 seconds, and good specimens were obtained. From this result, it is considered that the optimum amount of the silica gel is 350 g.

When two kinds of granular and granular silica gels having different shapes are spread in a container having the same capacity as above, 150 g of the granular material can cover 6 mm of the thickness of the container. 200 g of silica gel has a thickness of 8 mm. In the case of granular silica gel, 150 g can cover 5 mm of the thickness of the container, and 200 g of 7 m.
m thick. From the above results, the use time of the microwave oven was the same even when the shape was different, but the difference in the shape caused a difference in the coating thickness, and the granular silica gel 3
The thickness equivalent to 175 g when 50 g is divided into two is 6
mm to 7 mm.

The heating time depends on the size and thickness of the container and the thickness of the plant, which is a raw sample. For this reason, a commercially available microwave oven with a power of 600 W is used, 350 g of silica gel, 2 cm × 14.5 cm inside the container. In the same manner as in Example 1, the plants, which are the raw samples, were laid so as not to overlap with each other to obtain a colorful dried body. Shiba Zakura (scientific name: Ph
loxsubulate) and Pansy (scientific name Vio)
Table 2 shows the conditions and the results.

[Table 2] In the case where the number of plant solids contained in the dossier is small or the plant is thin, the heating time and the cooling time for standing can be reduced as shown in Table 2 above.

After heating in a microwave oven, it is allowed to cool, and the temperature is lowered. This means that if you hold the container with your bare hands, it cools so as not to burn, but even the same plant has different thickness and moisture depending on the part. Since the amount is different, the purpose is to allow water to cool, thereby adjusting the amount of water to be different depending on the part of the plant, which is a raw sample, to give a beautiful color.

Table 3 shows the relationship between the heating time and the cooling time.

[Table 3] From the above table, it was possible to produce a colorful dried body in a short time so as not to be compared with the conventional production method. However, the red flowers of the anthocyans change their acidity when the water of the plant is drained, so that they turn blackish. This can be colored by citric acid or tartaric acid, but can be restored by using a commercially available red reducing agent.

Example of Drying Herbs The rapid drying method of the present invention was applied to 20 lavender flowers, 20 chamomile flowers, 80 thyme leaves, 30 pineapple mint leaves, and 60 salmon leaves. . Table 4 shows the drying conditions.

[Table 4] In addition, about thyme and pineapple mint, put in tissue, hold at medium temperature of iron for 10 seconds,
It was subjected to drying. Two chamomile on Nitto tea bag,
Two mint pieces and 36 lavender wheels were used and compared for 2 minutes. Table 5 shows the results.

[Table 5] The color and fragrance were excellent. Table 6 shows a comparison of herbs with the conventional drying method.

[Table 6]

Example of Drying Tea Leaves About 10 young leaves of tea are also treated with about 50 leaves in the same manner as herbs.
Microwave heated for ~ 80 seconds and allowed to cool for about 10 minutes. Table 7 shows the results.

[Table 7] It was bright in color and fragrant.

Example of Method for Preserving Plant Specimen The dried product produced by the rapid drying method of the present invention can be a commercially available transparent bag such as a plastic bag that can be opened and closed. In other words, put a UV-cut transparent film that is temporarily used for office work on the entire surface of the plastic bag,
What is necessary is just to put a dried body in this. If the size of the plastic bag is about the size of a postcard, put about 20 g of silica gel and iron powder Cairo (deoxidizer), remove air as much as possible, and seal the plastic bag.
Store in a cool, dark place.

Example in which a plant specimen is made into a card and preserved A dried body as a plant specimen produced by the rapid drying method of the present invention is temporarily fixed on a backing sheet with a silicon paste. An adhesive UV-cut transparent film cut to a size larger than the backing paper is attached to the surface to which the dried body as the plant specimen is attached so that air bubbles do not enter. Similarly, on the back side, a film is pasted to be larger than the base, the protruding front side and the back side film are pasted together, so that a margin of 2 to 3 mm remains, and the excess film is cut off.

Example of Planting and Preserving a Plant Specimen A dried body as a plant specimen produced by the rapid drying method of the present invention is put in a forehead, and an adhesive UV-cut transparent film is stuck on the surface of glass. It could be preserved for a long time with beautiful natural colors. If you want to keep the card for a longer period of time, stick a deoxidizer (iron powder) and desiccant (silica gel) with double-sided adhesive tape on the back of the card created by the above method, and cut the card with a masking tape with adhesive UV cut Stop on a forehead glass plate with a transparent film, and apply a thick layer of silicone paste on the masking tape. Cut the aluminum foil for the kitchen into large pieces, bleed the air, paste the dull side of the aluminum foil toward the silicon glue side, and when the glue settles, cut off the protruding part with scissors.
Furthermore, if necessary, aluminum tape is applied to the entire back surface to reinforce it, and the surrounding area is enclosed in a forehead.

Example of Preserving Pasted Plant Specimens A 240-degree paper file is applied to a wooden plate for handicrafts, the surface of the plate is smoothed, and a desired acrylic paint is applied.
When the acrylic paint has dried, apply a thin layer of silicone paste to the plate. Before the silicone paste has dried, place the plant specimen on it and press lightly with tissue paper. When the silicone paste dries, apply the silicone paste to the table of the plant specimen, and when the silicone paste dries, apply a fixixif on this.
After 3 minutes, apply fixifif again. Apply oily resin solution once. When the resin solution dries, apply the UV-cut aqueous acrylic resin solution and apply wax to complete it, but if you want a thickness, apply the acrylic resin alternately vertically and horizontally, dry and collect the work to get the desired thickness Apply over to the top. When finished to the desired thickness, apply acrylic resin solution for finishing and polish it with wax containing silicon to finish it to make a plant specimen.

Example in which the plant specimen is made three-dimensionally and detached. The backing paper of the adhesive UV-cut transparent film is peeled off, the plant specimen divided for each part is placed on the adhesive surface, and after pressing lightly with a finger, another adhesive sheet is removed. In order to make it sealed with a sweet UV cut transparent film, hold the margin band along the contour of the plant firmly with a modeler etc.
Cut out 2mm larger with scissors. The plant specimens made separately for each part are assembled so that they can be seen three-dimensionally by using silicon paste on boards and small items.

Example in which a plant specimen is made three-dimensional and stored, and an oxygen scavenger is used. Peel off the silica paper on one side of the double-sided tape, attach the plant specimen divided into individual parts on the adhesive surface, and apply silicon paste to the surface of the plant specimen. Paint. When the silicon paste has dried, apply the fixifif, and after 2 to 3 minutes, apply the fixifif again, and place the adhesive washi film between the adhesive surface of the double-sided tape and the plant specimen. Peel off the other side of the double-sided tape, apply the washi film, apply a cloth, press with a medium-temperature iron, and adhere. A kraft solution for pressed flowers is applied to the front side of the plant specimen, and when dried, a UV-cut acrylic resin solution is applied. After drying, wax is applied. With scissors, 1-2m
Cut and attach the edge of m and paste it three-dimensionally with silicon paste to make a plant specimen. The specimen is put in a forehead, a commercially available iron powder and a desiccant are put on the back of the forehead, and the back of the forehead is sealed with an aluminum wheel.
