Description

  The present invention relates to a method for producing granular excrement disposal materials for humans and / or animals, and in particular, treatment of granular excrement for humans and / or animals using okara recovered from a tofu production process as a raw material. The present invention relates to a material and a manufacturing method thereof.

Okara, which is produced in large quantities in the process of producing soy milk during tofu production, contains protein and fatty acids and is prone to acidification, so most of it is discarded and incinerated. However, Okara contains proteins, lipids, fats, and organic fibers, and has previously been used as a foodstuff or feed, but because of consumer preference or increased cost. Is no longer used. Therefore, the collected okara is dried and reused without generating a rotten odor. Okara dried in this way is blended with, for example, paper pulp recovered from waste paper diapers, or blended with an adhesive such as corn starch, and the granulated product has a water content of 10 to 10. It is reused by drying to 20% and using it as a granular excrement disposal material for animals such as livestock and pets.

However, because Okara is discharged from tofu manufacturers in a state of containing a lot of water, even if it is collected, the one that has ran out of time, ran into odor, and produced a bad odor has little use. It is exclusively incinerated. This will incinerate large amounts of protein, fat and organic fibers, which is a problem from the perspective of resource utilization. In addition, for example, even dry okara contains protein, fat, and organic fiber, so it does not change, so when it absorbs moisture or gets wet, it rots or wrinkles occur. It is a problem.

  In general, a granular excrement disposal material forms a lump by adhering particles wet with urine etc. during use, and makes it possible to separate wet and dirty parts from non-wet parts after use. Therefore, in the present invention, the granular excrement disposal material is formed by adhering particles wet with urine or the like during use to form a lump, and wet and soiled parts after use from a part that does not get wet. It is formed so that it can be divided. In the present invention, the granular excrement disposal material having a coating layer portion retains the property of forming a lump aggregate by being wetted after use and adhering to the coating layer portion due to adhesion between the coating layer portions. In this way, it is possible to separate wet and soiled parts from non-wetting parts after use. When the coating layer portion is formed in this way, it is not necessary to give the granular core portion a wet and sticking property, and the core portion is formed from the okara from which water-soluble components have been removed, and the water absorption function of okara In addition, the water retaining function allows the core portion to have a water retaining or water absorbing function. In the present invention, when the granular excrement disposal material having a coating layer portion is wet during use, the wet and permeated water is retained or absorbed by the core portion and retained, and the coating layer portion is wetted after use. Thus, the function of the granular excrement disposal material can be divided and held in the core portion and the covering layer portion so as to adhere to each other by adhesion between the covering layer portions to form a lump aggregate. The covering layer portion is formed so as to cover at least a part of the surface of the granular material forming the core portion with a material having such a property that the surface layer of the particles wets and adheres with urine or the like. In this invention, the coating composition which forms such a coating layer part can be formed with paper dust and the material which has adhesiveness, for example, the mixture of the water absorbing resin which has adhesiveness.

  In the present invention, the okara from which the water-soluble components have been removed is mixed with a substance having a bactericidal action less than that of the okara in order to prevent the occurrence of soot, but the generation of soot reduces the water content. Therefore, in order to more reliably prevent the occurrence of soot, the water content is preferably 12% by weight or less, preferably 10% by weight or less, for example, 7% by weight or less. In the present invention, the coating layer portion is wetted at the time of use, and the coating layer portion adheres to the okara powder or paper powder from which water-soluble components have been removed. The functional resin is mixed. Therefore, in the present invention, the granulation mixture forming the granulated product contains okara from which water-soluble components have been removed, and in a smaller amount than the okara, a substance having a bactericidal action, or a substance having a bactericidal action and It can be formed by containing a highly water-absorbing resin or a substance having a bactericidal action, a highly water-absorbing resin and a material having a deodorizing function. In this case, the granulation mixture that forms the granulated product contains, for example, 95% by weight or more of okara from which water-soluble components have been removed on a dry basis, and the remaining content of 5% by weight or less. A substance having a bactericidal action, or a substance having a bactericidal action and a highly water-absorbing resin, or a substance having a bactericidal action, a highly water-absorbing resin and a material having a deodorizing function can be formed. In the present invention, the mixture for granulation can be granulated to form a granular material, and the granular material can be used as a granular excrement disposal material having no coating layer, and the granular material can be used as a core material. These can be coated with a coating composition to form a granular excrement disposal material having a coating layer.

  In the present invention, the granulation mixture can be 95% by weight or more, preferably 95 to 99% by weight of the granulated mixture recovered from the tofu manufacturer and made into okara excluding water-soluble components. In this case, the remaining portion of 5% by weight or less, preferably 1% by weight or less on a dry basis can be a substance having a bactericidal action, and the substance having a bactericidal action and a superabsorbent resin in a total amount. Can be included. In the case of a granulation mixture containing a superabsorbent resin, the superabsorbent resin functions as a lubricant, so that it can be easily formed into a granular material by molding in the presence of water by a molding means such as extrusion molding. Let However, in the case of the excrement disposal material having a coating layer, the granulation mixture is for granulation of the granular core, and in this case, if the content of the superabsorbent resin in the granular core is large, In order to avoid this, since the swelling of the superabsorbent resin becomes large during water absorption, the granular shape of the granular core part may be damaged and the coated granule may be destroyed. The content is preferably as low as 5 weight percent or less, 3 weight percent or less, or 1 weight percent or less. In this case, the highly water-absorbing resin is preferably a highly water-absorbing resin having adhesiveness. When a highly water-absorbing resin having adhesiveness is used, the high-water-absorbing resin having adhesiveness adheres the powder particles of okara excluding water-soluble components or substance particles having a bactericidal action to the powder particles of the okara. Thus, it is possible to give the granulated product the desired water absorption and give a stable shape. The amount of the superabsorbent resin used in the granular excrement disposal material is selected in consideration of the water absorption of the granulated particles and the stability of the particle shape at the time of water absorption. It is preferable.

  In the present invention, okara excluding water-soluble components is mainly vegetable fiber, and its particle size is the pulverized particle size of soybean soaked in water during tofu production, but the fiber material is compressed in the granulation process. However, it is thought that the entanglement between the fibers becomes strong as it is crushed or shrunk, but the presence of organic fibers with a large particle size in the granulating material is to obtain a homogeneous granulated product. It is not preferable because it makes it difficult. In the present invention, in order to form a granular excrement disposal material with a particle size of 1 mm or more, Okara is pulverized to a particle size that is easy to granulate, for example, a particle size of 5 mm or less, preferably 4 mm or less. It is preferable to keep it. Okara pulverization is a step of removing water-soluble components from okara, that is, pulverizing okara particles to a particle size of 5 mm or less, preferably 4 mm or less in heated water at a temperature of room temperature or higher, or It is preferable to further sift through the sieved large particles and repeat the sieving and grinding operations to adjust the particle size. In the present invention, okara pulverization can be carried out dry or wet. In the case of wet pulverization, okara from which water-soluble components are removed in the pulverization step can be preferably produced by pulverization in heated water. Further, when pulverizing by a wet method, it is preferable to pulverize by avoiding generation of dust and the like. Therefore, even in the case of Okara with a low water content, the pulverization step can be performed wet, and the mixing step can also be performed in a state containing water. In addition, mixing of the okara excluding the water-soluble component thus produced, the substance having a bactericidal action or the substance having a bactericidal action, and the regenerated superabsorbent resin, the water-soluble ingredient is mixed by, for example, a screw feeder. In the process of transporting the removed okara, a substance having a bactericidal action or a substance having a bactericidal action and a superabsorbent resin can be added to the okara and mixed by a mixing action of a screw feeder.

  In the present invention, in the case of a granular excrement disposal material having a coating layer, when the water necessary for granulation is not covered by the moisture contained in okara, water is added to the granulation mixture prior to granulation. Then, the mixture for granulation mixed with water is granulated in a granulator. In the present invention, the granulator used for granulation includes, for example, a screw type extrusion granulator that granulates a granulation mixture having a relatively high moisture content, and a granulator having a relatively low moisture content. There are roll-type extrusion granulation apparatuses such as a disk pelleter and a ram-type extrusion granulation apparatus for granulating a granule mixture. However, it is not limited to these granulators, and other granulators such as other extrusion granulators, dish type, drum type rolling granulators, briquetting type, etc. There is a compression granulator. In the present invention, when granulating with a screw-type extrusion granulator, the moisture content of the granulation mixture is 25 to 50 weight percent, but when granulating with a roll-type extrusion granulator, The moisture content of the granule mixture is 10 to 25 weight percent. It is preferable to extract the water-soluble component with heated water while crushing raw okara so that the water content of the okara from which the water-soluble component has been removed does not greatly exceed these moisture, and filter the extract. If the moisture content of Okara from which water-soluble components have been removed greatly exceeds the moisture content required for granulation, a dehydrator is provided prior to the granulation process by the granulator, which is required for granulation. The moisture content can be adjusted so as to be within the range of the moisture content.

  In the present invention, the granular excrement disposal material is preferably granulated, for example, into a granulated material having a particle diameter of 1 mm or more in order to avoid generation and scattering of dust due to collapse or separation as much as possible. When granulated into particles having a particle size of millimeters or more, for example, it becomes difficult to disperse into the room from a toilet box, and even if it is disseminated, it is easy to pick up the particles, which is preferable in maintaining indoor hygiene. However, in these cases, the presence of particles of 1 mm or less or the presence of particles of 3 mm or less is not completely excluded. In the present invention, the granulated material and the coated granular material can be formed into a spherical shape, a columnar shape, a granular shape, a granular shape, other shapes, or a shape in which these are mixed. In this invention, the granular excrement disposal material which has a coating layer part is a covering granular material which has a coating layer part which covers a granular core part, and a particle size is formed in the said granular core part as much as a coating layer part. Is preferably formed into particles having a particle size of 2 millimeters or more, preferably 3 millimeters or more. The granular core portion of the granular excrement disposal material having this coating layer portion may be any particle having a particle size of 1 millimeter or more, and the shape of the granular material is not particularly limited. The granular core has a particle size of 1 millimeter or more, and can be, for example, spherical particles, columnar particles, hollow particles, granular particles, massive particles, powder particles, and other shapes. In the present invention, the granular material or granular core having a particle size of 1 mm or more can be produced by granulating the granulating mixture in the presence of water or water having a temperature of room temperature or higher. In the present invention, in order to increase the water absorption capacity and water retention capacity of the granular excrement disposal material, in addition to the regenerated water absorbent resin, a water absorbent resin can be blended in the core.

  In the present invention, the coating composition is one or more kinds of paper so that when the granular excrement disposal material gets wet with excrement such as urine, the adjacent granular excrement disposal material particles can adhere to each other. Contains powder and one or more materials having adhesive properties. Moreover, powdery pulp materials such as non-standard sanitary paper waste materials or sanitary paper cutting waste discharged from the sanitary paper manufacturing process can be used as such paper powder. Such powdery pulp materials include non-standard sanitary paper waste or sanitary paper cutting waste discharged from the sanitary paper manufacturing process, such as thin paper, thin paper waste, sanitary paper, sanitary paper waste, toilet There are paper paper, toilet paper waste, tissue paper paper, tissue paper waste, decorative paper paper, decorative paper waste, dust paper paper, dust paper waste, paper cotton, paper cotton waste, paper towel, paper towel waste, etc. Waste materials that can be used as coating materials include newsprint, newsprint, magazine waste, mechanical pulp, mechanical pulp waste, chemical pulp, chemical pulp waste, semi-chemical pulp, semi-chemical pulp waste, cotton-like pulp, cotton-like pulp waste, Wood pulp, wood pulp waste material, waste paper pulp ground material, paper powder, fluff pulp, pulp ground material other than the above Pulp waste material, water-absorbing fiber waste material, water-absorbing resin waste material, paper powder containing water-absorbing resin, paper powder generated during bookbinding, paper powder generated during non-woven fabric production, paper powder generated during papermaking process, or hygienic material manufacturing There are paper powders that are sometimes generated or a mixture of two or more pulverized products. All of these are pulverized to a particle size of 0.5 millimeters or less, preferably 0.3 millimeters or less, more preferably 0.1 millimeters or less, and used for forming the coating layer portion.

In the present invention, the coating composition forms the outer layer portion of the granular excrement disposal material, and when the granular excrement disposal material is wetted with urine, the particles of the granular excrement disposal material are separated from each other. For example, a substance having an adhesive function, i.e., an adhesive, is used so that the particles of the excrement disposal material can be easily bonded to each other through the respective coating layer portions. It can be formed by blending with a coating composition. In this case, a superabsorbent resin having an adhesive function (adhesiveness) can be used as the substance having an adhesive function.
In the present invention, examples of the adhesive forming the coating composition include a paste such as α starch and a superabsorbent resin such as sodium polyacrylate. Examples of the paste functioning as an adhesive include potato starch, wheat starch, sweet potato starch, corn starch, tapioca starch, rice starch, dextrin, starches such as pre-gelatinized starch, acrylamide, polyvinyl alcohol, carboxymethyl cellulose, Sodium alginate can be used, or two or more of these can be used in combination. Other adhesives include gelatin, superabsorbent resin, vinyl ester, bentonite, polyvinyl alcohol (PVA) (Poval: trade name), pullulan, casein, or gelatin, and these are used alone. Or a mixture of two or more of these. Examples of alcohol-soluble adhesives include hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), polyvinyl pyrrolidone, or (PVP). Two or more kinds can be mixed and used. Gelling agents such as gelatin and polyvinyl alcohol are preferable because they can form a granulated material having a granulated material having a particle size of 5 millimeters or less.

  In the present invention, a surfactant can be used to supplement the water absorption rate of okara. The surfactant is added to the granulated material before granulation. The addition amount of the surfactant is preferably 1% by weight or less, preferably 1 to 0.05% by weight of the granulated material. As the surfactant, a commercially available anionic surfactant, cationic surfactant, amphoteric surfactant or nonionic surfactant can be used. In this case, the surfactant is dissolved in a solvent such as water and used with or without diluting the solution. The dry granulated product is produced by granulating the mixture to which the surfactant solution is added to form a granulated product having a particle size of 1 millimeter or more, and drying the formed granulated product. In this way, the addition of the surfactant makes the dried organic material waste pulverized material obtained by granulation easy to wet with water, and the dried granulated organic material waste pulverized material, that is, granular material. The water absorption of the excrement disposal material can be accelerated.

  In the present invention, the okara powder excluding the water-soluble component of the raw material used for the granular excrement disposal material reduces the generation of odor during storage, and is sanitary and safe. In addition, in order to give a free touch and feel no wrinkles or unpleasant odor, the granular excrement disposal material has a moisture content of 12% by weight or less, preferably 10% by weight or less, more preferably It is dried to 8% by weight or less. In order that the dried coated granular material does not generate dust or the like, the granulated material is preferably formed into a granular material having a particle size of 1 millimeter or more.

Yes, and more preferably 55% by weight of paper powder. Further, the amount of the superabsorbent resin forming the coating layer portion is 40% by weight or less, preferably 35% by weight or less with respect to the coating layer portion. The use of sodium acrylate as the water-absorbing resin for forming the coating layer portion is because the binding between particles becomes strong in the process of forming the coating layer portion, so the amount of sodium acrylate used should be 30 weight percent or less. The lack of adhesive strength is preferably replaced with a starch-based superabsorbent resin. In the present invention, when the content of the water-absorbent resin in the coating layer portion of the granular excrement disposal material is 5 weight percent or less, the wet granular excrement treatment materials adhere to each other. However, it is possible to disperse the excrement disposal material particles bound in the water and disperse it to the material. In the present invention, in the coating layer portion, a part of the water-absorbent resin can be replaced with an adhesive such as glue.

In this way, the excrement disposal material having a coating layer portion is formed by binding the collected excrement treatment material wetted with the excreted urine attached to each other. Since it solidifies, the excrement disposal material particles that are contaminated with excrement can be easily separated. In the case of solid excreta, it adheres around the excrement and binds to each other so as to wrap the excrement, so that the odor of excrement is adsorbed by the excrement disposal material. It will not be scattered around. In the present invention, since a paste such as polyvinyl alcohol or flour is mixed as an adhesive in the covering layer portion of the granular excrement disposal material, it adheres to human or animal excrement and excretes. Is wrapped in a lump shape, and cleanup is simple and easy. Further, when a deodorizing agent and / or a highly water-absorbing resin is mixed in the core portion of the animal excrement treating material, the deodorizing property, water absorbing property and water retaining property are further improved as the excrement treating material. In the present invention, the coating layer formed on the core may be formed by blending various water-absorbing resins in addition to various pulp material powders or paper powders so that the water-absorbing and bonding functions are appropriate. it can. In this case, for example, in addition to pulp material powder or paper powder, the coating layer portion is a water absorbent resin having a water absorption and adhesion function, a highly water absorbent resin having a relatively large water absorption amount, and a water absorbent resin that functions as a thickener. Can be blended and formed at an appropriate ratio determined experimentally.
