Description

[0001] The present invention relates to a grain dehumidifying agent,

The present invention relates to a grain dehumidifying agent and a method for producing the grain dehumidifying agent, and more particularly, to a grain dehumidifying agent which is dehumidified by using grains processed to absorb external moisture, thereby eliminating the danger and harmfulness to the human body, ≪ / RTI >

Desiccant is a substance used to absorb moisture in the air to lower the humidity.

Sodium and sulfuric acid are used as moisture absorbing materials, but they are difficult to commercialize because of the danger. Therefore, silica gel and other polymer compounds or calcium chloride are used as a dehumidifying agent. In particular, silica gel is used as a re-wetting agent for foods such as confectionery and steaming .

Silica is silicon dioxide, and silica gel is a transparent vitreous granular solid made by washing and drying a material obtained by treating an aqueous solution of sodium silicate with hydrochloric acid or sulfuric acid with water molecules attached to the silicate. Silica gel is active when water is used in a concentration of 2 to 10 percent, and there are numerous fine holes on the surface, so that the surface area in contact with moisture in the air is wider and absorbs moisture. Therefore, it is widely used as a dehumidifying agent for food processing using such properties.

However, when silica gel reacts with water, it has a property of generating heat of about 26 to 30 degrees. When a person swallows silica gel contained in the packaging material of foods such as Kim, etc., weak burning of digestive organs such as esophagus and stomach There is a risk of wearing it.

In addition, when the sila car gel is inflated and cracked, there is a risk that the glassy debris of the silica gel may be stuck to the digestive organs or the like and be injured.

On the other hand, silica gel uses a strong acid during the production process. For this reason, the silica gel is washed with water several times to remove the acid.

In this process, acid wastewater is generated, which causes environmental pollution.

In addition, silica gel has a limitation in sucking moisture, and when it reaches a certain point, the dehumidifying effect no longer occurs, and there is also a problem that reuse of silica gel is also difficult.

Therefore, a method for solving such problems is required.

The grain dehumidifying agent according to an embodiment of the present invention may include the packaging material 10 and the grain 20 as shown in FIG. 1, with the risk of harmfulness to the human body being removed and the reuse being easy.

The packaging material 10 may be formed of a porous material so that a receiving space is formed therein and air can flow.

More specifically, the packaging material 10 is made of a porous material, and the corners of each of the four sides are compressed in the same manner as the thermal fusion, and are sealed, and a space for accommodating the cereals 20 described later can be formed therein.

At this time, it may be advantageous that the size of the hole formed for allowing the air to flow is formed to be smaller than the size of the grain 20 to be described later so that the grain 20 does not flow out to the outside.

In such a configuration, the inner grain 20 of the packaging material 10 can be prevented from flowing out to the outside of the packaging material, and the moisture outside the packaging material 10 can be effectively absorbed.

At this time, it is preferable that the packaging material 10 is formed of a material usable for a microwave oven.

In this configuration, when the grain 20 described below reaches the dehumidifying capacity limit, the grain drying agent according to the present invention can be easily reused by re-drying using a microwave oven.

Here, if the packaging material 10 is formed of a porous material so that air can flow, the dehumidifying agent in the packaging material 10 is formed to be able to be protected, and if moisture is effectively absorbed outside the packaging material 10, Configurations and shapes may be varied without limitation.

On the other hand, the grain 20 can be drawn into the receiving space and processed to absorb moisture outside the package 10. [

In the grain dehumidifying agent according to an embodiment of the present invention, various processes in which the grain 20 is formed to absorb moisture outside the packaging material 10 will be described later.

Generally, a silica gel dehumidifying agent is used for the dehumidification of food inside foods such as steaming. However, the user can inadvertently inhale the silica gel, and the silica gel may be broken inside the food and contaminate the food.

The grain 20 according to an embodiment of the grain dehumidifying agent according to the present invention is harmless to the human body and does not contaminate the food even when the grain dehumidifying agent is broken inside the food.

Therefore, if grain 20 processed to absorb moisture outside the packaging material is used in a receiving space of the packaging material, it is possible to prevent contamination and damage of food even when the grain dehumidifying agent is harmless to the human body, Lt; / RTI >

In addition, the grain 20 can be more easily obtained from around us, and the grain 20 can be advantageously harmless to the human body because it does not require chemicals in the process of dehumidifying.

Next, a description will be made in detail of the processing in which the grain 20 of the grain desiccant agent according to the present invention is formed so as to be absorbable.

Referring to FIG. 2, the grain 20 may be formed into a porous structure by evaporating moisture through at least one of heating and pressing.

For example, there is a method of expanding cereals through rapid heating, a method of rapidly heating at high pressure in a sealed high-pressure vessel using explosive gun puffing, followed by rapid release to normal pressure, and an extruder The moisture inside the grain can be evaporated by the method of extruding and expanding, the method of rapid heating using microwave in a microwave oven, the method of rapid heating by hot hot air, etc., so that the porous structure can be formed.

That is, the grain 20 processed through at least one of heating and pressurization is formed into a porous structure so that the grain 20 is bulged to increase its volume and absorb external moisture. For example, it is formed like a " .

Therefore, the grain 20 expanded in volume and formed into a porous structure is formed to have a wider surface area in contact with moisture in the air and to be able to absorb moisture more easily, so that it is possible to dehumidify the inside of the packing material of foods, Even if accidentally inhaled, it is harmless to human body.

Further, it can be easily obtained from the periphery, and the manufacturing process can be simplified and the cost can be reduced.

When the grain 20 is at a dehumidifying limit, it can be dried and reused by using a microwave oven or the like.

At this time, a plurality of grains 20 may be provided according to the desiccation force desired by the user, and a plurality of grains 20 may be introduced into the receiving space of the packaging material 10, as shown in FIG.

Meanwhile, the grain 20 formed by the porous structure may be formed into a plate shape by press-molding.

2, when pressure is applied to the expanded grain 20 through the process described above, it may be pressed between the grains 20 and thus formed into a plate shape. For example, a so-called "Quot; and " pop-up ".

In this configuration, it is possible to reduce the volume of the expanded and bulky grain 20 so as to enter the receiving space of the packaging material more easily, and to increase the absorption rate per area.

4, the grains 20 may be formed in a rectangular plate shape according to the shape of the packaging material 10, and may be formed in a circular plate And the shape of the grain 20 is not limited as long as the grain 20 is drawn into the receiving space of the packaging material 10 to be dehumidified.

Further, if the grain 20 can be processed so as to absorb moisture outside the packaging material 10, there is no limitation on the processing method and the material may be varied.

Meanwhile, the cereal 20 may be at least one of white rice, brown rice, black rice, barley, barrel, sardine, sorghum, oats and corn.

Therefore, even when absorbed by humans, it is harmless to the human body, and even when it is mixed with a dehumidifying object such as food, the object can be prevented from being contaminated with the dehumidified object.

Here, if the grain 20 can be formed so as to be able to absorb external moisture through the above-described processing, there is no limitation on the kind of the grain.

As described above, the constitution of one embodiment of the grain dehumidifier according to the present invention has been described. Hereinafter, one embodiment of the grain dehumidification method will be described in detail.

The components of the grain dehumidifying agent are as described above in the description of one embodiment of the grain dehumidifying agent manufacturing method described later, so a detailed description thereof will be omitted.

The packaging material preparing step S10 may be a step of preparing a packaging material 10 formed of a porous material so that a receiving space is formed therein and air can flow outside and inside.

At this time, one end of the packaging material 10 is opened, and it may be advantageous that the grain 20 to be described later is drawn in.

And, the grain processing step S20 may be a step of processing the grain 20.

At this time, the processing step S20 may include an expanding step (S21) of expanding the cereal 10 through at least one of heating and pressurizing.

That is, the processing step S20 includes the step of expanding the grain 10 through at least one of heating and pressing and forming the grain 10 into a porous structure so that the grain 10 can absorb external moisture .

In this process, the grain 20 may be formed, for example, as a so-called " tumbler ".

In addition, the processing step S20 may further include a compression step (S22) of compressing and shaping the cereal after the expansion process to form a plate shape.

More specifically, through the above-described process, pressure is applied to the expanded grain 10 to be pressed between the grains 20, and thus can be formed into a plate shape, and can be formed, for example, as a so-called " have.

In this process, it is possible to reduce the volume of the expanded and bulky grain 20, to more easily enter the receiving space of the packaging material, and to increase the water absorption rate per area.

The grain 20 formed through the above-described process can be dehumidified in the inside of the packaging material such as kim, and is harmless to the human body even if it is accidentally inhaled.

In addition, it can be easily obtained at the periphery, and when the dehumidification limit is different, it can be dried by using a microwave oven or the like to facilitate reuse.

Meanwhile, the grain introduction step S30 may be a step of drawing the grain 20 into the receiving space of the packaging material.

That is, it may be a step of inserting the cereal 20 processed in the processing step S20 into the receiving space of the package 10 through the open side of the package 10.

Then, the packaging material sealing step (S40) may be a step of sealing the packaging material 10 in which the grain is introduced.

The method for sealing the packaging material 10 may include mechanical bonding, thermal bonding, adhesion using an adhesive, or the like. The packaging material 10 may be formed so that it is hermetically sealed to the human body and the inner grain 10 is not leaked. If so, there is no limit to the sealing method.

At this stage, it is possible to prevent the grain 20 from flowing out from the inside of the package 10 to the outside so as not to be mixed with a dehumidifying object such as food.

Meanwhile, the cereal 20 may be at least one of white rice, brown rice, black rice, barley, barrel, sardine, sorghum, oats and corn.

Therefore, even when absorbed by humans, it is harmless to the human body, and even when it is mixed with a dehumidifying object such as food, the object can be prevented from being contaminated with the dehumidified object.

At this time, if the grain 20 can be formed so as to be able to absorb external moisture through processing, it can be said that the kind of the grain 20 is not limited.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims.
