Description

Technical Field

[0003] , ,

[0001] The present invention belongs to the technical field of cat litter, and specifically relates to cat litter and a method for manufacturing the same.

Background Art

[0002] Cat litter is used by the owner to conceal the excrement of the cats being raised and has excellent water absorption. Cat litter is usually used together with a cat litter tray, and an appropriate amount of cat litter is placed in the cat litter tray for use. A trained cat will enter the cat litter tray when it needs to excrete and cover the excrement with the cat litter. As a general cat litter, paper pulp processed into small granular form imitating sand is used, thereby imparting water absorption. There is also granular cat litter using a physical desiccant such as silica gel. Generally, chemical products such as antibacterial agents, deodorants, and preservatives are added. Since cat litter coagulates into lumps when it comes into contact with water, it becomes easier for the owner to clean the feces and urine of the cat, and the pollution of the usage space can be reduced. For example, the millet plant cat litter disclosed in publication number CN114982646A uses all plant-based raw materials, is pollution-free, has no irritating odor, is easily soluble in water, and can be flushed down the toilet. The natural plant enzyme added to the cat litter can instantaneously decompose the ammonia absorbed by the cat litter. The product of the millet plant cat litter has a flaky or granular structure and a diameter of less than 3 mm, so the feeling when the cat steps on it is close to that of natural sand and it is less likely to stimulate the feet. Therefore, it has been actually measured that cats are easily receptive and do not require an adaptation period. However, there are still problems to be solved in the conventional cat litter and its manufacturing method. That is, due to the cat litter being too soft, the usability is reduced, and the production cost increases due to the use of many natural materials. Furthermore, since it is difficult to test the pH of the cat's urine, the health status of the cat cannot be appropriately grasped. To solve that problem, the present inventors propose a new cat litter and a method for manufacturing the same.

Summary of the Invention

[0003] The present invention aims to provide cat litter and a method for manufacturing the same that solve the problems described in the background art above. To achieve the above objective, the present invention provides the following technical means.

[0004] Furthermore, the present invention provides a method for producing cat litter, comprising the following steps S1 to S7. S1. Preparation of raw materials: Prepare 40-60 parts by weight of bamboo extract, 10-20 parts by weight of soybean meal powder, 5-10 parts by weight of sweet potato meal powder, 4-8 parts by weight of pine wood chips, 30-50 parts by weight of bentonite, 5-8 parts by weight of diatomaceous earth, 5-8 parts by weight of volcanic rock granules, 4-6 parts by weight of perlite powder, 0.5-1.5 parts by weight of anthocyanin, and 4-6 parts by weight of thickener. S2. Initial mixing of raw materials: The bamboo extract, soybean meal powder, sweet potato meal powder, and pine wood chips are uniformly mixed to obtain a primary mixed powder. S3. Polishing: The bentonite, diatomaceous earth, volcanic rock granules, and perlite powder are placed in a ball mill and polished and mixed to obtain a second mixed powder. S4. Liquid preparation: Water is added to the anthocyanin and mixed uniformly to form a mixed solution. S5. Secondary mixing: The primary mixed powder and the mixed liquid are first thoroughly mixed, and the thickener is added. Then, the second mixed powder is added and thoroughly mixed, and the thickener is added again to obtain a paste-like ointment. S6. Granulation: The paste-like ointment is put into a granulator and granulated to form mixed granules. S7. Drying: The mixed granules are dried and then cooled to obtain the cat litter product.

[0005] Preferably, the method for producing the bamboo extract includes the following steps. S101, after washing and drying the bamboo branches, they are crushed in a crusher to obtain crushed bamboo powder raw material. S102, the crushed bamboo powder raw material is added to the NaOH solution and immersed for 1 to 3 hours. After immersion, an acidic solution is added to adjust the pH value to obtain a bamboo aqueous solution. The pH value of the bamboo aqueous solution is 5.6 to 6.6. S103. Ethyl acetate and ethyl ether are added to the bamboo aqueous solution, and the bamboo extract is obtained by distillation.

[0006] Preferably, the method for producing the soybean meal powder includes the following steps. S201, thoroughly wash the soybean meal, and then dry the washed soybean meal in a dryer. S202, the dried soybean meal is placed in a crushing device and crushed, and the crushed soybean meal is sieved to obtain primary soybean meal powder. S203, After moistening the primary soybean meal powder with an appropriate amount of distilled water, the pH value is adjusted, and the primary soybean meal powder with the pH value adjusted is placed in a dryer and dried again to obtain the soybean meal powder as a finished product. Preferably, in S203, the drying temperature of the dryer is 120°C to 160°C, and the drying time is 30 to 60 minutes, and the primary soybean meal powder is dried until the moisture content is 6 to 10%. Also, in S202, the crushed soybean meal is sieved through a 70 to 90 mesh sieve. Preferably, the sweet potato meal powder is produced by the same method as the method for producing soybean meal powder, except that soybean meal is replaced with sweet potato meal. Preferably, in the granulation step of S6, the mixed granules formed are granulated to have a diameter of 3 to 5 mm and a length of 0.4 to 1.2 cm.

[0007] Compared to conventional technology, the present invention offers the following beneficial effects. (1) By adding bamboo extract, the present invention makes the raw materials environmentally friendly and healthy, and enhances safety during use. Furthermore, by adding soybean meal powder, sweet potato meal powder, and pine wood chips, not only can raw material costs be reduced, but the softness can also be improved. In addition, water absorption can be increased. When discarded, it can be buried directly in the ground and used as soil nutrients, making it environmentally friendly, biodegradable, safe, and non-polluting. Moreover, since the raw materials are renewable, the resource utilization rate can be increased. (2) The cat litter of the present invention is manufactured by mixing anthocyanins with other raw materials in a predetermined proportion, granulating the mixture, and drying it. By adding anthocyanins, the health status of a pet can be determined based on the color change reaction depending on the acidity or alkalinity of the pet's excrement. For example, if a pet consumes a lot of meat, the excrement becomes acidic, and the anthocyanins turn red. If a pet consumes a lot of vegetables, the excrement becomes alkaline, and the anthocyanins turn green, and in severe cases, yellow. On the other hand, in normal cases, the anthocyanins do not change color. This allows for constant monitoring of the pH of the cat's excrement, and enables timely assessment of the cat's health status. (3) In this invention, by adding diatomaceous earth to the raw materials, the odor adsorption capacity of the cat litter can be enhanced, and the deodorizing performance of the cat litter can be effectively improved. Furthermore, by adding volcanic rock granules, the antifungal properties of the volcanic rock granules can be utilized to suppress the growth of mold in humid environments and provide high antibacterial properties. In addition, since volcanic rock granules also have a high heat retention and insulation effect, the quality of use of the cat litter can be improved. Moreover, by mixing anthocyanins together with pine wood shavings in the gaps between the volcanic rock granules, the anthocyanins can be effectively protected, and the effective use period of the anthocyanins can be extended. Even if it remains in the air for a long period of time, natural deterioration due to chemical reactions is prevented, and the lifespan of the cat litter can be extended.

[0022] (Principles and advantages of the present invention) In this invention, by adding bamboo extract, the raw materials can be made environmentally friendly and healthy, and safety during use can be enhanced. Furthermore, by adding soybean meal powder, sweet potato meal powder, and pine wood chips, not only can raw material costs be reduced, but softness can also be improved. In addition, water absorption can be increased. When discarded, it can be buried directly in the ground and used as soil nutrients, making it environmentally friendly, biodegradable, safe, and non-polluting. Moreover, since the raw materials are renewable, resource utilization can be increased. The cat litter of the present invention is manufactured by mixing anthocyanins with other raw materials in a predetermined proportion, granulating the mixture, and drying it. In this invention, by adding anthocyanins, the health status of a pet can be determined based on the color change reaction depending on the acidity or alkalinity of the pet's excrement. For example, if a pet consumes a lot of meat, the excrement becomes acidic, and the anthocyanins turn red. If a pet consumes a lot of vegetables, the excrement becomes alkaline, and the anthocyanins turn green, and in severe cases, yellow. On the other hand, in normal cases, the anthocyanins do not change color. This allows for continuous monitoring of the pH of the cat's excrement, enabling timely assessment of the cat's health status. Furthermore, in this invention, anthocyanins are first mixed with materials such as pine wood shavings, and then mixed with bentonite, diatomaceous earth, volcanic rock granules, and perlite powder. In particular, because volcanic rock granules have fine voids, the anthocyanin material mixed with pine wood shavings fills the voids in the volcanic rock granules, effectively protecting the anthocyanins from the effects of acidic or alkaline substances in the air. This extends the shelf life of the anthocyanins. Furthermore, in this invention, by adding diatomaceous earth to the raw materials, the odor adsorption capacity of the cat litter can be enhanced, effectively improving its deodorizing performance. In addition, by adding volcanic rock granules, the mold resistance of the volcanic rock granules can be utilized to suppress mold growth in humid environments, thereby imparting high antibacterial properties to the cat litter. Moreover, since volcanic rock granules also have a high heat retention and insulation effect, the quality of use of the cat litter can be improved.

[0023] The following experiment was conducted using cat litter manufactured by a conventional method and cat litter manufactured by the method of the present invention. The experimental details and results are shown in the table below. TIFF2025086406000001.tif50150

[0024] From the above experiments, it was confirmed that the cat litter produced in Examples 1, 2, 3, and 4 showed improved water absorption, deodorizing properties, antibacterial properties, and heat retention properties. In particular, Example 3 was confirmed to be the best example. Although embodiments of the present invention have been described above, those skilled in the art can make various changes, modifications, substitutions, and variations to these embodiments without departing from the principles and spirit of the present invention.
