DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow melting agent containing amino acid residues as a main component.

[0002]

2. Description of the Related Art Conventionally, in a soy sauce manufacturing plant or a food processing plant, soy sauce, amino acids,
Manufactures miso and other products. In these factories, steamed soybeans, roasted and crushed wheat are added with koji and koji-produced, and then added with saline, fermented for about 6 months, aged, and matured. The brewed soy sauce is produced by pressing with a pressing machine. For amino acids, instead of fermenting "moromi", raw materials such as soybeans and wheat are immersed in approximately 18% hydrochloric acid and heated to hydrolyze proteins in soybeans and wheat to produce amino acid solutions. Generate. Thereafter, an alkali component such as sodium carbonate is added to neutralize the solution, and the amino acid solution is filtered through a filter to produce a transparent amino acid. Then, an amino acid that can be produced in a short time and at low cost is added to this brewed soy sauce whose production cost is high, and this is provided at low cost as a chemical soy sauce.

[0003]

However, in the above-mentioned soy sauce manufacturing plant and food processing plant, a large amount of moromi cake after squeezing "moromi" and amino acid cake which is a residue after filtering the amino acid solution are produced in large quantities. There is a problem in that the natural environment is destroyed when discharged and dumped into the ocean or illegally dumped on the ground or in the ground. Also, drying these residues as feed for livestock requires a great deal of expense, and while other recycling methods are being sought, soy sauce production and food processing plants, etc. There has been a demand for effective use of mash cake, amino acid cake, and the like that are discharged as residues after the production of amino acids.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to produce a snow melting agent by paying attention to the fact that amino acid cakes and mash cakes contain salts. It is an object of the present invention to provide a snow melting agent and a method for manufacturing the snow melting agent, which do not require disposal costs, can prevent the destruction of the natural environment due to illegal dumping, are lightweight as a snow melting agent, and are easy to handle.

[0005]

According to the present invention, a soybean or wheat is heat-treated in hydrochloric acid to hydrolyze proteins in those components to form an amino acid solution, and an alkali component is added to the amino acid solution. It is composed of a snow melting agent whose main component is a residue obtained by filtering and neutralizing a neutralized solution neutralized by a filtration filter.

[0006] The present invention also relates to a soy sauce mash cake obtained by squeezing soy sauce mash in hydrochloric acid to hydrolyze proteins in those components to form an amino acid solution, and to add an alkaline component to the amino acid solution. The neutralized solution neutralized by the addition of is added with a filtration filter.

[0007] The residue of the filtered squeezed juice may be mixed with crushed shirasu powder and dried.

It is preferable that the mixing ratio of the shirasu flour to the filtered squeezed juice residue is 17: 3 to 15: 5 by weight.

[0009]

The snow-melting agent of the present invention is a process for producing an amino acid solution by decomposing soybeans, wheat, or mash residue after squeezing mash with acid, and removing the amino acid residue after filtering the amino acid solution. The main component. Amino acid residue, which is a residue after squeezing the amino acid solution, contains salt, and the soybean and wheat epidermis and fiber in the amino acid residue are colored black by oxidation with acid to melt snow. Excellent action and can be effectively used as a snow melting agent. Therefore, there is no need to dispose, and the destruction of the natural environment due to illegal dumping can be prevented.

[0010] It is more preferable that shirasu powder obtained by crushing shirasu is mixed with amino acid residue and dried. Since the shirasu powder has low hygroscopicity, the degree of amino acid residue mixed with the shirasu powder in the peripheral snow melts out and decreases, and the snow melting action can be maintained. In addition, the shirasu particles enter the particles of the amino acid residue, so that the air can easily flow therethrough, and the drying speed increases.

[0011] In the step of producing an amino acid solution by decomposing the mash residue after soybean, wheat or mash is squeezed with acid,
Road, ground,
Used as a snow-melting agent to melt snow that has fallen on the roof surface and other places. The amino acid residue has a high salt content due to the acid used to decompose proteins in the amino acid production process and the alkali component to neutralize the acid, and the epidermis and fiber of cereals such as soybeans and wheat. Alternatively, other organic substances are colored black by oxidation with an acid, so that the amino acid residue is effectively used as a snow melting agent because of its excellent solar heat collecting action.
Therefore, there is no need to dispose of the amino acid residue, and the destruction of the natural environment due to illegal dumping can be prevented.

[0012] Further, by mixing shirasu powder obtained by crushing shirasu with the amino acid residue, the drying speed is increased, and the degree of melting and flowing out as snow melting agent in the peripheral snow is reduced, so that the snow melting action is maintained. Sex becomes longer.

It is preferable that at least the amino acid residue among the amino acid residue and the shirasu powder to be mixed is a dried amino acid residue. The amino acid residue discharged at the factory can be shipped as a snow melting agent while a predetermined amount of shirasu powder is mixed with the amino acid residue that has been dried and stored in the winter season when the snow melting agent is required, while drying and storing the amino acid residue sequentially. In addition, deterioration of the amino acid residue can be prevented for a long time by the drying treatment.

[0014] It is further advantageous that a mixture obtained by mixing the amino acid residue and shirasu flour and drying the mixture is used as a snow melting agent. Mixing shirasu flour with amino acid lees having a high moisture content enables uniform and prompt drying, thereby saving drying costs. Further, the shirasu powder having low hygroscopicity can maintain the snow melting action for a long time.

[0015]

The present invention will be specifically described below by way of examples. Snow melting agent according to an embodiment of the present invention, soybean, wheat, or mash depressed mash after squeezing mash with acid to produce an amino acid solution, the amino acid solution after filtering the amino acid solution, the amino acid residue after filtering It is the main component. When producing amino acids at a soy sauce or miso production plant, soy or wheat raw materials are immersed in hydrochloric acid of approximately 18% concentration, heated for a required time, and the protein contained in soy or wheat. Is hydrolyzed to produce an amino acid solution. Thereafter, an alkali component such as sodium carbonate (Na 2 CO 3) is added to neutralize the solution, the amino acid solution is filtered through a filter, the transparent amino acid solution is squeezed, and the residue after squeezing is amino acid residue. . The amino acid residue is soybean or wheat epidermis or fiber, or other organic matter, and remains in a state of being oxidized and colored black by hydrochloric acid. FIG. 1 in Table 1 below shows an experimental example in which the amino acid solution was neutralized with sodium carbonate (Na 2 CO 3) and the components of the amino acid residue immediately after being filtered with a filtration filter were analyzed. In addition, sodium chloride
Raw materials such as soybeans and wheat are thermally decomposed with hydrochloric acid, then neutralized with sodium carbonate, and filtered to obtain an amino acid solution, which is produced as follows. 2HCl + Na2 CO3 → 2NaC
L + H2 CO3

From the composition ratio of the amino acid residue as shown in FIG. 1 in Table 1, the converted value of sodium chloride generated in consideration of the generated ions is 10.1% by weight (official analysis method). After drying the amino acid residue for about 10 days in the sun, organic matter = 60.9, ash content = 20.1, and water content of 19.
0, which is 17.1 in terms of weight% based on the total amount of sodium chloride. When the amino acid residue is completely dried with a dryer or the like, organic matter = 75.2 and ash content = 24.
8. The converted value for the whole of sodium chloride = 21.1. Then, the specific gravity of the whole amino acid cake that has been completely dried at this time is 0.426.

The dried amino acid residue, calcium chloride generally used as a snow melting agent, and shirasu flour described later were used as samples, and 5 g of each of these samples was added to 50 g of ice for the elapsed time. Table 2 shows an example of the experiment on the amount of deicing.

As described above, the amino acid residue contains about 20% of sodium chloride in a completely dried state, and further, when hydrolyzed with hydrochloric acid, the residue is oxidized and colored black so that the residue has a solar heat collecting effect. Excellent and can be expected as a snow melting agent.

In FIG. 2 of Table 2, 34 minutes and 43 minutes
As shown in the case of minutes, as compared to calcium chloride, which is generally used as a snow melting agent, calcium chloride has a higher snow melting effect at the beginning of use, but after about 30 minutes the amount of snow melting decreases More and gradually increases the amount of snowmelt. This means that it has high persistence as a snow melting agent and can exert a snow melting action for a long time. On the other hand, although calcium chloride has high immediate effect, it begins to deliquesce in a short period of time and melts, and it can be understood that the persistence as a snow melting agent is inferior to that of the amino acid cake of the present application. In other words, it can be seen that the amount of ice melting increases with the passage of time, and amino acid cake is more excellent as a snow melting agent. Therefore, by effectively utilizing the amino acid residue as a snow melting agent, the cost of disposal is eliminated. In addition, it is possible to prevent the destruction of the natural environment due to dumping into the ocean, illegal dumping onto the ground or underground, etc., and it is possible to manufacture a snow melting agent at a low cost because the amino acid residue to be discarded is used as a raw material. Furthermore, since the snow melting agent produced from amino acid cake has a small specific gravity of 0.426, the weight per unit volume is light, and the handling when packaged in bags or the like is easy, and the storage and storage in a warehouse, or The transportation work can be easily performed, and the transportation cost can be reduced.

In addition to the amino acid lees, ripened "moromi" is used as a raw material, and moromi lees discharged when the brewed soy sauce is squeezed is used as a raw material. It may be manufactured. At this time, the mash cake is immersed in hydrochloric acid and heated for a required time to hydrolyze proteins remaining in the mash cake to produce amino acids. Thereafter, the mixture is neutralized by adding an alkali component, and then filtered through a filtration filter, and the amino acid residue as a residue after the filtration is used as a snow melting agent. Even in this case, since the snow melting agent is manufactured using moromi lees as a raw material, the cost of disposal is unnecessary, and the destruction of the natural environment due to the dumping of moromi leash into the ocean, illegal dumping onto the ground or underground, etc. can be prevented. Can be used to produce a snow melting agent at low cost.

The amino acid residue after squeezing the amino acid solution is
As shown in FIG. 1 of Table 1, the moisture content is 52.5%, and the time for the drying treatment is long. Also, when sprayed as a snow melting agent, the degree of dissolution in the surrounding snow and loss of the same as calcium chloride is high, and the time of staying in the snow is short, so that the snow melting action cannot be sustained. Therefore, in the embodiment, the continuity of the snow melting action is enhanced by mixing and drying the shirasu powder obtained by pulverizing shirasu (volcanic ejecta) with the amino acid residue. Table 3 shows an experimental example of the evaporation rate of water in the amino acid meal with respect to the drying time when each amino acid meal mixed with shirasu flour was dried in the sun.

From FIG. 3 in Table 3, the mixing ratio of the shirasu flour to the amino acid meal is about 17: 3 to 15: 5, and the drying time in solar drying is appropriately about 265 hours = about 11 days. In addition, if you mix whitebait with amino acid cake,
Shirasu powder particles enter the amino acid cake particles, and the air can easily flow therethrough. The drying speed is fast, and the drying cost can be reduced as compared with the case of drying the amino acid cake alone. In addition, when the mixing ratio of the shirasu powder increases, the transpiration rate increases, but on the contrary, the weight increases and handling becomes unsuitable. Further, the drying treatment is not limited to the sun drying, and may be forcibly dried by a hot air dryer. However, in the forced drying, the fuel cost is relatively high.

Next, the mixing ratio of the snow melting agent (A) obtained by drying only the amino acid residue and the amino acid residue and white powder is 1%.
A snow-melting agent (B) dried at 7: 3, a snow-melting agent (C) dried at a mixing ratio of amino acid lees and shirasu powder of 15: 5, and a snow-melting agent (D) composed of dried calcium chloride. Table 15 shows experimental examples of the amount of thawing after 6 minutes by adding 15 g of each to 150 g of ice, and the amount of thawing of the ice itself.

As shown in FIG. 4 in Table 4, after the lapse of 6 minutes, the melting amount of the snow melting agents (B) and (C) obtained by mixing shirasu powder in the amino acid cake and drying was calculated using calcium chloride. Is smaller than the melting amount of the single snow melting agent (D) or the single snow melting agent (A) of the amino acid residue, and larger than the ice melting amount of the ice itself. This means that the snow melting agents (A) and (D) have a high hygroscopicity, and at the same time as being sprayed, are easily melted and easily washed away in the peripheral snow, so that the snow melting action on the snow cannot be sustained.

On the other hand, the snow melting agents (B) and (C) obtained by mixing shirasu flour with amino acid lees at a ratio of about 17: 3 to 15: 5 have low hygroscopicity of shirasu flour, The degree of amino acid residue mixed with shirasu powder melts out into the peripheral snow and flows out less, so that the snow melting action can be maintained for a long time while staying in the snow that has fallen for a long time. In addition, since the specific gravity is light, even when sealed in a plastic bag or other packaging bag, it is lighter in weight and easier to handle than snow melting agent (D), and is stored and stored in a warehouse or on the road site. Can be easily transported. At the same time, the transportation cost is reduced.

In the method for producing a snow melting agent according to the present invention, the amino acid liquid obtained by filtering the amino acid solution at a soy sauce production plant or a food processing plant is mixed with shirasu flour, and the mixture is air-dried using the sun. Alternatively, the drying treatment is performed by using forced drying by a hot air dryer. Further, the present invention is not necessarily limited to this. For example, only amino acid cake produced in a factory is dried and stored sequentially, and a predetermined amount of white powder is added to the amino acid cake that has been dried and stored in winter when a snow melting agent is required. May be shipped as a snow-melting agent while mixing, so that the amino acid residue can be inexpensively used as a snow-melting agent while preventing deterioration over time.

When the snow melting agent according to the present invention is used, about 20 kg is sealed in a plastic bag or the like and stored in a warehouse or the like in advance. In winter, for example, the snow that has fallen freezes due to a decrease in temperature and is easily sprayed on roads such as hills and curved roads that hinder vehicle traffic. It can secure traffic and prevent traffic accidents. Furthermore, because of the deliquescence of commonly used salt snow melting agents such as sodium chloride and calcium chloride, when sprayed on road surfaces, etc., the melting speed of snow is fast, and it melts and freezes in about half a day. While the prevention state cannot be sustained, the snow melting agent of the present invention can maintain the persistence of the snow melting action for a long time, effectively use the amino acid residue that has been disposed of, and save disposal costs.
This has the effect of preventing the destruction of the natural environment due to illegal dumping and the like.

[0028]

As described above, according to the snow melting agent of the present invention, the soybean, wheat, or moromi cake after squeezing moromi is decomposed with acid to produce an amino acid solution. After the amino acid liquid after filtration of the amino acid liquid is mainly used, soybean and wheat are decomposed with acid to produce an amino acid liquid, and the amino acid liquid after filtering the amino acid liquid, or after crushing the mash. The amino acid liquid is produced by decomposing the mash residue with acid, and the snow melting agent is produced by effectively utilizing the amino acid residue generated at this time. It is possible to prevent the destruction of the natural environment due to illegal dumping inside. Further, since the raw material to be disposed of is used, the production cost of the snow melting agent is reduced. Furthermore, since the manufactured snow melting agent has a light weight per unit volume and is easy to handle, storage and storage and transport operations can be easily performed, and transport costs are low.

Further, by mixing and drying the shirasu powder obtained by crushing shirasu with the amino acid residue, the particles of the shirasu enter the particles of the amino acid residue and the air can easily flow therethrough. Weight is reduced. In addition, volcanic eruption Shirasu can be effectively used at low cost. Furthermore, since the white powder has a low hygroscopicity, the amino acid residue mixed with the white powder melts out into the peripheral snow and flows out at a low rate, and the snow melting action can be maintained while remaining in the snow that has fallen for a long time. .

In the step of producing the amino acid solution by decomposing the mash residue after squeezing soybean, wheat, or moromi, etc. with an acid, the amino acid residue after filtering the amino acid solution is used for road, ground, roof, In addition, soybeans and wheat are decomposed with acid to produce an amino acid solution by using snowfall as a snow-melting agent to melt the snow, and the amino acid residue after filtering the amino acid solution or the moromi after pressing the moromi. The snow melting agent can be manufactured by effectively utilizing the amino acid residue obtained by decomposing the residue with acid and then filtering, and the cost of disposal of the amino acid residue is unnecessary, resulting in marine dumping, illegal dumping on the ground and underground, etc. The destruction of the natural environment can be prevented. Further, the snow melting agent can be manufactured at low cost by using the raw material to be disposed of. Further, the manufactured snow melting agent has a light weight per unit volume, is easy to handle, can be easily stored, transported, and transported at low cost.

Further, by mixing the amino acid residue with the shirasu powder obtained by crushing the shirasu, the shirasu powder has low hygroscopicity, and the amino acid residue mixed with the shirasu powder is dissolved into the snow around the periphery and flows out. Low, so that it can stay in the snow that has fallen for a long time and continue its melting action. Also, shirasu flour can be used as an extender to some extent for amino acid meal.

[0032] In addition, of the mixed amino acid residue and the shirasu flour, at least the amino acid residue is made of a dried amino acid residue. In winter, when the agent is required, it can be shipped as a snow melting agent while mixing a predetermined amount of shirasu flour with the amino acid residue that has been dried and stored, and can be used at a low cost as a snow melting agent while preventing deterioration of the amino acid residue over a long period of time.

Further, by drying the mixed amino acid cake and white powder, the white particles enter the amino acid cake particles having a high water content while being filtered, and air is generated in the amino acid cake. The drying speed is increased by uniformly flowing the amino acid residue, and the drying cost can be reduced as compared with the case of drying the amino acid residue alone.
