When ferrous sulfate is oxidized, divalent iron ions contained in the ferrous sulfate are changed to trivalent iron ions, and divalent iron ions are lost from the ferrous sulfate. If ferrous sulfate loses divalent iron ions, the deodorizing action of divalent iron ions cannot be used. Therefore, with this deodorizer, the deodorizing effect of ferrous sulfate may not be fully utilized. In addition, the deodorizing agent impregnates the obsidian stone with the first liquid, then dries the obsidian stone with hot air, and further impregnates the obsidian stone with the second liquid, Since it is made by drying with hot air, a plurality of steps are required for producing the deodorant.

  Deodorizers in which at least one of iron sulfate and iron chloride is used in the iron ion-containing material use iron sulfate and iron chloride that contain a large amount of divalent iron ions, thereby reducing the deodorizing action of the iron ions. It can be used reliably and sufficiently, and the odor caused by ammonia, hydrogen sulfide, and mercaptan can be reliably deodorized.

  A deodorizer in which at least one of starch and carboxymethylcellulose is used as a solidifying material fixes an iron ion-containing material and a β-ray generating material in the form and maintaining the form of starch or carboxymethylcellulose.

  The details of the deodorizer according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a deodorizer 10A shown as an example, and FIG. 2 is a diagram showing an example of a manufacturing process of the deodorizer 10A. The deodorizer 10A is made of a mixture (not shown) of ferrous sulfate powder 11 (iron ion-containing material), zirconium ore powder 12 (β-ray generating material), and starch 13 (solidifying material). (See FIG. 2). The deodorizer 10A is produced by granulating (molding) the mixture and then drying it. The deodorizer 10A is formed into a substantially cylindrical pellet. The deodorizer 10A has a length L1 in the range of 0.5 mm to 20.0 mm and a diameter L2 in the range of 0.5 mm to 10.0 mm. The deodorizing agent 10A has hydrolyzability in which the starch 13 is not gelatinized and easily dissolves in water and decomposes.

  The ferrous sulfate powder 11 contains a large amount of divalent iron ions, and has a function of deodorizing odors by utilizing a chemical reaction of divalent iron ions. In addition, it can replace with the ferrous sulfate powder 11 and can use the iron chloride containing a bivalent iron ion. Moreover, the iron which mixed the ferrous sulfate powder 11 and iron chloride in a predetermined ratio. An ion-containing composite powder can also be used. Similar to the ferrous sulfate powder 11, iron chloride has a function of deodorizing odors by utilizing a chemical reaction of divalent iron ions. When divalent iron ions are oxidized and reduced, ammonia is converted to ammonium sulfate, hydrogen sulfide is changed to iron sulfide, mercaptan is decomposed into carbon dioxide, and the odor caused by these substances is deodorized. To do.

  For example, in the case of ammonia odor, after ammonia molecules adhere to the surface of ferrous sulfate, the ammonia molecules chemically react with divalent iron ions, change into various body compounds, and become stable. Is deodorized. In the case of ammonia molecules, a chloride compound is generated from anions such as sulfate ions, nitrate ions, and hydrochloric acid ions, which are counter ions of iron, and divalent iron ions form amine complex salts. In this compound, ammonia molecules 6 are taken in with respect to iron molecules 1, so that the ammonia odor is effectively removed. When ferrous sulfate or iron chloride is oxidized and divalent iron ions are changed to trivalent, the deodorizing action of ferrous sulfate is lost.

  Zirconium ore powder 12 emits beta rays from a natural radioactive substance contained in a trace amount. In the zirconium ore powder 12, oxidation of the ferrous sulfate powder 11 and iron chloride is prevented by using β rays. In place of the zirconium ore powder 12, an anion powder can be used, and a β-ray generating composite powder in which the zirconium ore powder 12 and the anion powder are mixed at a predetermined ratio is used. You can also. Anion powder emits beta rays from a natural radioactive substance contained in a trace amount. In the anion powder, oxidation of the ferrous sulfate powder 11 and iron chloride is prevented by using β rays. Divalent iron ions are in an unstable state and change to stable trivalent iron ions in the air in a short period of time, but when divalent iron ions are irradiated with β-rays, they change to trivalent. Is prevented, and a natural change from divalent to trivalent can be prevented. By using the zirconium ore powder 12 and the anion powder, the divalent state of the iron ions contained in the ferrous sulfate powder and iron chloride can be maintained for a long period of time.

  Starch 13 becomes a solidification medium and fixes ferrous sulfate powder 11 and zirconium ore powder 12 therein. In the deodorizer 10 </ b> A, the pellet form is maintained using the form maintaining function of the starch 13. In the deodorizer 10A, the ferrous sulfate powder 11 and the zirconium ore powder 12 are dispersed substantially uniformly in the starch 13. In addition, it can replace with starch 13 and can use potato pulp (dry starch grounds) or carboxymethylcellulose, and can also use the composite material which mixed starch 13 and carboxymethylcellulose by the predetermined ratio. A composite in which potato pulp and carboxymethyl cellulose are mixed at a predetermined ratio can also be used. Potato pulp is a powder and contains a large amount of starch.

  As the starch, at least one of raw material starch and modified starch can be used. As the raw material starch, at least one of corn starch (corn starch), potato starch, wheat starch, rice starch and tapioca starch can be used. As the modified starch, at least one of a starch derivative, a starch degradation product, and a pregelatinized starch can be used. As the starch derivative, at least one of etherified starch, esterified starch and crosslinked starch can be used. As the starch degradation product, at least one of roasted dextrin and British gum, oxygen-modified dextrin, acid-decomposed starch, and oxidized starch can be used.

  Based on FIG. 2, an example of the manufacturing procedure of the deodorizing agent 10 </ b> A will be described as follows. The deodorizing agent 10A is manufactured by mixing a ferrous sulfate powder 11, a zirconium ore powder 12, and starch 13 (or potato pulp) to form a mixture containing a predetermined amount of water, and a mixture thereof. Is formed from a granulation step 15 for forming a plurality of pellet-like deodorizing agents 10A and a drying step 16 for drying the deodorizing agents 10A.

  In the kneading step 14, a ribbon mixer 17 (first kneader) and a stirring hopper 18 (second kneader) located below (downstream side) of the mixer 17 are installed. The ribbon mixer 17 is placed on the equipment tower 19. The ribbon mixer 17 includes a kneading tank 20, a shaft 21, and a stirring ribbon 22. A duct 23 connected to the stirring hopper 18 is connected to the bottom of the kneading tank 20. The shaft 21 rotates in the clockwise direction and the counterclockwise direction by driving the electric motor. The stirring ribbon 22 extends in a substantially spiral shape so as to surround the shaft 21. In the kneading tank 20, ferrous sulfate powder 11, zirconium ore powder 12 and potato pulp 13 (powder) are charged, and although not shown, water and a pH adjuster (malic acid). And are injected. In the ribbon mixer 17, the stirring ribbon 22 is rotated clockwise and counterclockwise by the rotation of the shaft 21. The ribbon mixer 17 kneads the ferrous sulfate powder 11, the zirconium ore powder 12, and the starch 13 together with water and a pH adjuster to make a mixture containing a predetermined amount of moisture. In the kneading step 14, a paddle mixer or a screw mixer can be used as a kneading machine instead of the ribbon mixer 17.

  The stirring hopper 18 is disposed below the equipment tower 19. The stirring hopper 18 includes a kneading tank 24, a shaft 25, and a stirring blade 26. The shaft 25 rotates in the clockwise direction and the counterclockwise direction by driving the electric motor. The stirring blades 26 are arranged in at least two stages, and are located outward in the direction around the shaft 25 and extend so as to form a perfect circle in the direction around the shaft 25. The mixture kneaded by the ribbon mixer 17 flows into the kneading tank 24 through the duct 23. In the stirring hopper 18, the stirring blade 26 is rotated clockwise and counterclockwise by the rotation of the shaft 25. The stirring hopper 18 stirs the mixture. The mixture re-kneaded by the stirring hopper 18 moves from the hopper 18 to the belt conveyor 27 and is conveyed to the granulation step 15. In the kneading step 14, instead of the stirring hopper 18, a poni mixer, a vacuum backflow mixer, a nauta mixer, a high sludger, an Eirich mixer, a Henschel mixer, a power mixer, a combimix, or a Shugy mixer can be used as the kneading machine.

  In the granulation step 15, a semi-dry type / low moisture granulator 28 and a quantitative feeding machine 29 for feeding a predetermined mixture into the granulator 28 are installed. Although not shown, the granulator 28 is provided with a conical roller, a die, and a cutter. The mixture is fed from the belt conveyor 27 into the hopper 30 of the fixed dose feeder 29. The fixed amount feeder 29 puts a predetermined amount of the mixture into the granulator 28 while measuring the mixture. The mixture charged in the granulator 28 is pushed into a die by a conical roller, granulated into a cylindrical shape by a die, and then cut into a predetermined length by a cutter, to form a plurality of pellet-like deodorizers 10A. Processed. In addition, the granulation temperature in the granulator 28 is adjusted to 40 ° C. or less.

Starch 13, its bulk density is in the 0.13 g / cm ³ or more and 0.17 g / cm ³ or less. If the bulk specific gravity of the starch 13 is less than 0.13 g / cm ³ , the solidifying action of the starch 13 is weak, the form retention of the deodorant 10A is lowered, and the deodorant 10A may not be able to maintain the pellet form. When the bulk specific gravity of starch 13 exceeds 0.17 g / cm ³ , the specific gravity of starch 13 is significantly different from that of ferrous sulfate powder 11 and zirconium ore powder 12, and ferrous sulfate powder is contained in starch 13. 11 and zirconium ore powder 12 cannot be uniformly dispersed. Since the bulk specific gravity of the starch 13 is within the above range, the deodorizer 10A can maintain the pellet form. Further, the ferrous sulfate powder 11 and the zirconium ore powder 12 can be combined with the starch 13. It can be uniformly dispersed in.

  The mixing ratio of water to the total weight of the mixture (the ratio of water injected into the stirring tank 20) is in the range of 20 wt% or more and 30 wt% or less. When the mixing ratio of water is less than 20% by weight, the ferrous sulfate powder 11, the zirconium ore powder 12, and the starch 13 cannot be sufficiently kneaded, and the ferrous sulfate powder 11 and the zirconium ore powder are not mixed. 12 cannot be uniformly dispersed in the starch 13. Further, since the viscosity of the mixture is remarkably increased by kneading by the granulator 28 and a mixture that hardly exhibits fluidity is produced, the mixture is crushed in the granulation step 15 so that the pellet-like deodorant 10A cannot be produced. There is a case. When the mixing ratio of water exceeds 30% by weight, the mixture cannot be imparted with an appropriate viscosity by kneading by the granulator 28, and the viscosity of the mixture is remarkably lowered. 10A itself may not be made. In the production of the deodorant 10A, the mixing ratio of water to the total weight of the mixture is in the above range, so that a mixture having an appropriate viscosity and an appropriate fluidity can be formed in the granulation step 15, and sulfuric acid The deodorizer 10A in which the iron powder 11 and the zirconium ore powder 12 are almost uniformly mixed in the starch 13 can be produced.

  The weight ratio of the ferrous sulfate powder 11 to the total weight of the mixture is in the range of 10.0% by weight to 15.0% by weight. If the weight ratio of the ferrous sulfate powder 11 is less than 10.0% by weight, the deodorizing action of divalent iron ions contained in the ferrous sulfate powder 11 cannot be fully utilized, and the deodorizer 10A. The deodorizing effect in is reduced. The weight ratio of the zirconium ore powder 12 to the total weight of the mixture is in the range of 5.0 wt% or more and 10.0 wt% or less. When the weight ratio of the zirconium ore powder 12 is less than 5.0% by weight, β rays generated from the zirconium ore powder 12 cannot be sufficiently utilized, and ferrous sulfate is produced using the zirconium ore powder 12. The oxidation of the powder 11 cannot be prevented. The weight ratio of starch 13 to the total weight of the mixture is in the range of 75.0% to 85.0% by weight.

  In the drying process 16, a dryer 31 for drying the pellet-like deodorant 10 </ b> A produced in the granulation process 15 is installed. A belt conveyor 32 is disposed between the granulator 28 and the dryer 31. The dryer 31 includes a unit 35 having an entrance 33 and a discharge port 34, a belt conveyor 36 installed inside the unit 35, a heater (not shown) for heating the air to produce hot air, and heating A blower (not shown) that blows hot air produced by the air blower and an exhaust fan (not shown) that discharges the hot air to the outside of the unit 35 are formed. The belt conveyor 36 extends between the entry port 33 and the discharge port 34 of the unit 35. A large number of fine through holes are formed in the belt conveyor 36. The heater and the blower are installed between the conveyors 36. The exhaust fan is installed at the upper part of the unit 35.

  The pellet-shaped deodorant 10 </ b> A produced in the granulation step 15 is conveyed to the dryer 31 by the belt conveyor 32. The deodorizer 10A carried to the entrance 33 of the unit 35 by the conveyor 32 moves from the entrance 33 of the unit 35 to the belt conveyor 36 inside the unit 35, moves on the conveyor 36, and is discharged from the entrance 33 of the unit 35. Go to exit 34. The belt conveyor 36 slowly conveys the deodorizing agent 10A from the entrance 33 of the unit 35 toward the outlet 34 at a predetermined speed. The warm air produced by the heater is blown from the lower side of the belt conveyor 36 toward the upper side of the unit 35 by a blower. The warm air passes through the through hole of the conveyor 36 and is circulated through the inside of the unit 35 and is discharged to the outside of the unit 35 by the blower.

  The deodorizer 10 </ b> A is heated by warm air passing through the through-holes of the belt conveyor 36 or warm air circulating inside the unit 35. The part vaporizes. Here, the movement time from the entrance 33 to the discharge port 34 of the deodorizer 10A and the internal temperature of the unit 35 can reduce the moisture contained in the deodorizer 10A, and the starch 13 forming the deodorizer 10A. Is maintained at a temperature and a time during which no gelatinization occurs.

  Specifically, the moving time from the inlet 33 to the outlet 34 of the deodorizing agent 10A is 5 minutes or more and 20 minutes or less, and the internal temperature of the unit 35 is maintained in the range of 45 ° C. or more and 65 ° C. or less. Has been. When the movement time is less than 5 minutes and the internal temperature of the unit 35 is less than 45 ° C., the moisture contained in the deodorizer 10A is not vaporized and the moisture cannot be reduced. If the moving time exceeds 20 minutes and the internal temperature of the unit 35 exceeds 65 ° C., the deodorizer 10A is heated more than necessary, and the moisture contained in the deodorizer 10A is greatly reduced. Further, the starch 13 is gelatinized and solidified starch 13 may cause the deodorizing agent 10A to be extremely hardened, and the deodorizing effect in the deodorizing agent 10A may be lost. In the manufacture of the deodorant 10A, since the moving time from the inlet 33 to the outlet 34 of the deodorizer 10A and the internal temperature of the unit 35 are within the above ranges, while preventing gelatinization of the starch 13 forming the deodorizer 10A, The moisture contained in the deodorizer 10A can be appropriately reduced.

  In the drying step 16, a part of the moisture contained in the deodorizer 10 </ b> A is vaporized, and the deodorizer 10 </ b> A is dried more than in the granulation step 15, but not all of the moisture contained in the deodorizer 10 </ b> A is vaporized. The agent 10A is not completely dried. The deodorizer 10A that has undergone the drying step 16 is not gelatinized with the starch 13 contained therein, only the surface thereof is dried, and a predetermined amount of water is contained therein. The deodorizer 10A that has undergone the drying step 16 has a moisture content in the range of 7.0% to 15.0%, preferably in the range of 8.0% to 10.0%. If the moisture content of the deodorizer 10A is less than 7.0%, the deodorizer 10A is hardened more than necessary and becomes brittle, and the pellet form may not be maintained. When the moisture content of the deodorizer 10A exceeds 15.0%, the oxidation of the ferrous sulfate powder 11 is promoted by moisture, and the ferrous sulfate powder 11 may be oxidized in a short time. Since the moisture content of the deodorizing agent 10A is in the above range, the form retention is good and the pellet form can be maintained. Moreover, the oxidation of the ferrous sulfate powder 11 is not promoted, and the oxidation of the ferrous sulfate powder 11 in a short period can be prevented. The moisture content is a value measured using a heat drying / mass measurement type infrared moisture meter very similar to the loss on drying method.

The deodorizer 10A that has undergone the drying step 16 has a bulk specific gravity in the range of 0.3 g / cm ³ or more and 0.7 g / cm ³ or less, preferably 0.4 g / cm ³ or more and 0.5 g / cm ³ or less. It is in the range. The deodorizer 10A is light in weight because its bulk specific gravity is in the above range, and can be easily carried around a plurality of deodorizers 10A, even if a plurality of deodorizers 10A are installed together. The installation load can be ignored. The bulk specific gravity is a specific gravity obtained by calculating the volume from the dimension of the molded deodorant 10A and dividing the mass of the deodorant 10A. The bulk specific gravity is a value measured using an electronic peel and a measuring cup.

  The deodorizer 10A that has undergone the drying step 16 has a pH in the range of 4 or more and 7 or less. When the pH of the deodorizer 10A exceeds 7, it belongs to the alkaline region, and divalent iron ions contained in the ferrous sulfate powder 11 are easily changed to trivalent iron ions. The 11 to divalent iron ions are lost in a short time, and the deodorizing action of the divalent iron ions cannot be used for a long time. Since the pH of the deodorizer 10A is in the above range, it belongs to the acidic range, and the divalent iron ions contained in the ferrous sulfate powder 11 are not easily changed to trivalent iron ions. The divalent iron ions are not lost from the iron powder 11 in a short time, and the deodorizing action of the divalent iron ions can be used for a long time. The pH of the deodorizer 10A is a value measured using a pH meter.

  The deodorizing agent 10A prevents the short-term oxidation of the ferrous sulfate powder 11 in which the β rays generated from the zirconium ore powder 12 contain divalent iron ions. Since iron ions are difficult to change to trivalent iron ions and divalent iron ions are not lost in a short time from ferrous sulfate powder 11, the deodorizing action of divalent iron ions is ensured and long. The deodorizing effect of the deodorizer 10A can be maintained. This deodorizing agent 10A uses a chemical reaction that acts when divalent iron ions are oxidized and reduced, changes ammonia into ammonium sulfate, changes hydrogen sulfide into iron sulfide, and decomposes mercaptan into carbon dioxide. Can deodorize the odors that cause them.

  In the deodorizing agent 10A, since the starch 13 serving as a solidifying material fixes the ferrous sulfate powder 11 and the zirconium ore powder 12 in the starch 13, β-rays generated from the zirconium ore powder 12 are the first sulfuric acid. The iron powder 11 can be reliably irradiated to maintain the divalent state of iron ions for a long period of time, and the odor caused by ammonia, hydrogen sulfide, and mercaptan can be reliably deodorized. Since this deodorizer 10A has water decomposability and decomposes naturally, the deodorizer 10A can be discarded as it is. Since the deodorizing agent 10A is made by granulating a mixture of the ferrous sulfate powder 11, the zirconium ore powder 12, and the starch 13, it can be manufactured without requiring a plurality of steps.

The mixture re-kneaded by the stirring hopper 18 moves from the hopper 18 to the belt conveyor 27 and is conveyed to the granulation step 15.

In the granulation step 15, the mixture is charged from the belt conveyor 27 into the hopper 30 of the constant rate feeder 29. The fixed amount feeder 29 puts a predetermined amount of the mixture into the semi-dry / low moisture granulator 28 while measuring the mixture. The mixture charged in the granulator 28 is pushed into a die by a conical roller, granulated into a cylindrical shape by a die, and then cut into a predetermined length by a cutter, to form a plurality of pellet-like deodorizers 10A. Processed. The granulation temperature in the granulator 28 is adjusted to 40 ° C. or lower. Bulk density of the starch 13 is the same as that of starch 13 included in the deodorant 10A in FIG. 1, in 0.13 g / cm ³ or more and 0.17 g / cm ³ or less.
