DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a powdery deodorant used at home to suppress the generation of offensive odors from human and domestic animal excrement .

[0002]

2. Description of the Related Art In storage-type restrooms or livestock stalls installed in households, night soil decomposes and produces an odor, particularly when the night soil concentration is high, when the night soil is stored for a long time, or when the temperature is high. Countermeasures are required to make the users and nearby residents feel uncomfortable.

[0003] Therefore, deodorants have conventionally been used to suppress this kind of unpleasant odor. This deodorant is commercially available in liquid form or powder form.However, liquid deodorant can be used due to liquid dripping from the container or leakage due to falling of the container. , Sticking to hands and damaging skin,
In addition, there is a problem that floors, carpets, furniture, and the like are easily soiled. At present, powder deodorants that are easy to handle at the time of use are dominant. The powdered deodorant is produced by mixing powdered bactericides, organic acids, stabilizers, dyes, and a deodorant raw material composed of an oily liquid flavor, for example, to produce powder. After that, it is shipped in a state of being sealed and sealed with, for example, an aluminum vapor-deposited film and protected from moisture.

[0004]

However, the above powdery deodorant absorbs moisture before being sealed by an aluminum vapor-deposited film because of the high hygroscopicity of a disinfectant which is one of the raw materials. Due to this moisture, the powder becomes viscous during storage of the product, the powders adhere to each other, and are solidified by their own weight or compression by the weight of other products, and it is difficult to take out an appropriate amount at the time of use. There was a problem. This tendency has been a serious problem especially for products produced at high humidity such as during the rainy season.

The present invention has been made under such circumstances, and an object of the present invention is to provide a method for producing a powdery deodorant in which deliquescence is suppressed by granulation.

[0006]

The invention of claim 1 comprises a fungicide, an organic acid and a bulking agent , and the fungicide causes putrefaction of human waste.
In a method for producing a powdery deodorant, the upper half of the mixing tank is provided with a peripheral side wall inclined inward, and the mixing tank is rotated along the bottom wall around the central axis of the mixing tank. And a crushing rotor provided on the side wall near the bottom of the mixing vessel so as to rotate about a horizontal axis, and the mixing action by the mixing rotor and the crushing rotor Using a granulating device that performs granulation by crushing action, disinfectant, organic acid and extender powder, together with a liquid perfume and a solid, water-soluble moisture-absorbing agent, into the granulator. It is coated with the moisture-absorbing agent by charging and heating the inside of the device to melt the moisture-absorbing agent.
To obtain a deodorant consisting of granulated powder coated with the moisture-absorbing agent consisting of granulated powder in which the deliquescence of the disinfectant has been suppressed.

[0007]

For example, a perfume is added to a raw material comprising a bactericide, an organic acid, a stabilizer, and a water-soluble moisture-absorbing agent, and the mixture is heated and granulated using, for example, the perfume and the moisture-absorbing agent as a binder to prevent moisture absorption. A granulated powder coated with the agent is obtained.

The deodorant formed in the form of granulated powder has a smaller surface area as compared with the case where the deodorant is formed in the form of a powder, so that it is difficult to absorb moisture, and the deodorant is coated with a deodorant. As a result, the moisture absorbing effect is further suppressed, and the deodorizing agent has a very low deliquescence, and as a result, it is difficult to solidify.

[0009]

An embodiment of the present invention will be described. The deodorant of the present embodiment is, for example, a powdered bactericide composed of 2,2-disiobis- (pyridine-1-oxide) sold under the trade name of Hocside NS (manufactured by Hokuko Chemical Industry Co., Ltd.). A powdery organic acid made of malic acid for neutralizing ammonia, a powdered stabilizer (bulking agent) made of, for example, sodium sulfate, and an oily liquid made of, for example, butyl carbitol as a main component; Starting from a fragrance, a powdery dye made of, for example, Blue No. 1, and a solid water-soluble moisture-absorbing agent made of, for example, carboxymethylcellulose (CMC), granulating the raw material powder while adding the fragrance, for example. By doing so, a granulated powder constituted by combining a large number of powders is obtained.

Examples of the bactericides other than those described above include, for example, tetramethylthiuram, sodium methylthiocarbamate, ammonium methylthiocarbamate, N- (p
-Phenol) dimethylthiocarbamate, 1,2-benzisothiazolone, methylenebisthiocyanate and other organic sulfur-based germicides, sodium azide, N- (p-
Phenol) trichloroalkylcyan, nitrofuran, halogenacetamide, 1,3-dinonylbenzimidazolium bromide, 1- (2-hydroxyethyl) -1-benzyl-2-tridecylimidazolium,
Organic nitrogen-based germicides such as tris (hydroxymethyl) nitromethane, 1-N-piperazino-2-nitropropylbenzene, and 2,6-bisdimethylaminomethylcyclohexanone can be used. In addition to the above examples, for example, magnesium sulfate, ammonium sulfate, urea and the like can be used. In addition, polyethylene glycol (PE)
G), polyvinyl alcohol (PVA) or the like can also be used.

Next, a method for obtaining granulated powder will be described. FIG. 1 is a longitudinal sectional view of a rotary blade type mixing / stirring machine 1 for forming granulated powder of the present invention. In the figure, reference numeral 11 denotes a mixing tank. The mixing tank 11 has an upper half peripheral side wall 11a that is inclined inward, and an input port 1 at the upper end thereof.
2 is formed, and a cover plate 1 which can be opened and closed
3 are provided.

In the mixing tank 11, a rotary shaft 21 is provided at the center of the bottom wall 11b, the base end of which is connected to a drive unit 41, and the tip end 22 of which is substantially conical. Is formed. Further, at least one mixing rotary blade 23 extending radially toward the peripheral side wall 11a along the bottom wall 11b is disposed on the rotary shaft 21. The mixing rotary blade 23 has a tip on the side of the peripheral side wall 11a,
An upwardly curving flip-up portion 24 is formed, and a scooping surface is formed on the surface in the traveling direction along the length direction, and the scooping angle thereof (with the bottom wall 11b and the bottom wall 11b) increases as it approaches the base end from the distal end. Angle) is formed so as to gradually increase.

Further, a horizontal shaft portion 32 is provided on the peripheral side wall 11a.
The crushing rotary wing 31 rotated by the rotation is provided, and the base end of the shaft portion 32 is connected to the driving portion 42. A temperature controller (not shown) is provided on the outer wall of the mixing tank 11.

In the rotary blade type mixing / stirring machine 1 thus configured, the above-mentioned raw materials of the deodorizing agent are mixed and granulated to form a granulated powder-like deodorizing agent. That is, a disinfectant, an organic acid, a stabilizer, a dye, and a moisture-absorbing agent are charged into the apparatus 11 of the rotary blade type mixing and stirring machine 1.
2 and heating the mixing tank 11 with a temperature controller to about 60 ° C. while adding a fragrance through an addition port (not shown) on the upper part of the mixing tank 11 to mix the mixing rotary blades 23 and the crushing rotary blades. And 31 is rotated. At that time, the raw material of the deodorant is
The mixture is stirred while being scooped by the scooping surface formed on the mixing rotary blade 23.

At this time, in the vicinity of the tip of the mixing rotary blade 23 having a high peripheral speed, the raw material is jumped high by the jumping part 24 and the scooping surface, and the peripheral side wall 11a inclined inside the mixing tank 11 and It is rebounded by the conical tip 22 of the shaft 21 and falls near the base end of the mixing rotary blade 23, while near the base end where the peripheral speed is low, the scooping is performed so as to increase the scooping angle. Since the raised surface is formed, the raw material can be strongly scooped even if the peripheral speed is low. As a result, the raw materials are mixed and stirred while flowing smoothly in the mixing tank 11 as shown by the arrow in FIG.

Accordingly, the raw material is flipped up by the mixing rotary blades 23 in the mixing tank 11, and is uniformly dispersed, mixed and tumbled, whereby the raw material is granulated using, for example, a fragrance and a moisture-absorbing agent as a binder. Crushing rotor 3
The granulated powder is formed by crushing the lumps (lumps) generated at the time of granulation according to (1). At this time, by heating the inside of the mixing tank to about 60 ° C., at room temperature, the solid moisture-absorbing agent is melted and coated on the surface of the granulated powder.

In the above-described rotary blade type mixing and stirring machine 1, the shape of the granulated powder to be formed is changed by adjusting the number of rotations of the mixing rotary blade 23 and the rotary blade type mixing and stirring machine 31, for example. In the example, the ratio of each raw material is
S5%, malic acid 20%, sodium sulfate 70.5%,
The mixed flavor was 3%, Blue No. 1 was 1%, and CMC was 0.5%. The number of rotations of the mixing rotary blade 23 and the crushing rotary blade 31 was 2 respectively.
00r. p. m, 1500r. p. m, the mixing and stirring time was 6 minutes, and the temperature in the mixing tank 11 was about 60 ° C. to produce a deodorant, and a deodorant having a particle size of 0.8 mm was obtained.

With the deodorant thus obtained, the deodorant prepared by the conventional method is left for about one hour in a high-temperature and high-humidity state (temperature 28 ° C., humidity 80%) such as the rainy season. The powder deliquescences and adheres to it by just doing it, but it becomes a sticky state. However, even if it is left under the same conditions, it does not stick and keeps a smooth state.

As described above, it was recognized that the deodorant of the present embodiment had low deliquescent properties and was hard to be solidified, which may be due to the following reasons. That is, since the deodorant is made of granulated powder formed by combining each raw material powder, the surface area of the whole powder is reduced as compared with a case where the raw material powder is a mere mixed powder. For this reason, the contact area with the atmosphere is reduced, so that the moisture absorbing action is suppressed, and the deliquescence is reduced. Furthermore, the deodorant is mixed with a moisture-absorbing agent as one of the raw materials, and since this moisture-absorbing agent coats the surface of the granulated powder formed from other raw materials, it has a particularly high hygroscopic property. Very little contact between the air and other ingredients, including fungicides. For this reason, for example, the hygroscopic action of the germicide is suppressed, and the deliquescence is reduced, and as a result, the solidification is also reduced.

Since the moisture-absorbing agent used in the present invention is water-soluble, the moisture-absorbing agent coated on the surface of the deodorant is easily dissolved by a liquid such as human waste or washing water when used. The deodorizing action is performed promptly.

In the present invention, of the deodorant raw materials, for example, a bactericide, which is the raw material having the highest hygroscopicity, is surface-coated with an anti-hygroscopic agent, and then this is granulated with another raw material of the deodorant. You may make it.

[0022]

According to the present invention, the deodorant is formed as granulated powder by granulating the raw material, and the granulated powder is coated with a moisture-absorbing agent to suppress moisture absorption by the germicide. And the solidification property is reduced. Therefore, for example, it is difficult to solidify a product produced when the humidity is high.
