Description

Technical Field

[0001] The invention belongs to the technical field of oyster shell ultrafine powder, and particularly relates to a talcum powder rich in oyster shell ultrafine powder and a preparation method thereof. Background Art

[0002] Oyster shell ultrafine powder is a fine powder made from oyster shells through fine processing. The calcium carbonate in oyster shells is biosynthetic calcium carbonate, with a content of up to 94.3%, and the calcium content in the inorganic element composition is 39.8%, which makes oyster shell ultrafine powder a high-quality calcium source; oyster shells also contain a variety of trace elements such as phosphorus and strontium, and 17 kinds of amino acids, among which aspartic acid has a higher content. These ingredients make oyster shell ultrafine powder have more comprehensive nutritional value; the production process of oyster shell ultrafine powder mainly includes the steps of crushing, grinding and screening, among which wet ball milling ultrafine grinding is a commonly used production process, which can produce finer oyster shell powder, but it is necessary to pay attention to the loss of soluble substances. In addition, moisture and material filling rate also have a great influence on the particle size of oyster shell powder.

[0003] The application areas of oyster shell ultrafine powder are as follows:

[0004] Food industry: Oyster shell ultrafine powder can be used as a food additive, such as in the production of kimchi to increase the acid-reducing and crispness effect, or in the process of fruit juice fermentation to reduce acid and clarify the effect. At the same time, it can also be used as a food raw material for calcium supplementation and bone strengthening, improving the toughness and density of bones, and effectively preventing osteoporosis;

[0005] Pharmaceutical industry: Oyster shell ultrafine powder has the effects of astringency, analgesia, sedation and tranquilization in the pharmaceutical field. It can repair damaged gastric mucosa, remove bacteria and viruses in the stomach and intestines, and prevent gastroenteritis. At the same time, it can also directly act on the central nervous system, improve the function of the cerebral cortex, and effectively improve symptoms such as insomnia and neurasthenia;

[0006] Environmental protection: Oyster shell ultrafine powder has a porous structure, a large specific surface area and excellent adsorption, and can be used in environmental management. For example, it can be used to treat chromium-containing wastewater with a removal rate of up to 98.23%; it can also be used for the decolorization of methyl orange wastewater with a decolorization rate of up to 74.2%;

[0007] Agricultural field: Oyster shell ultrafine powder can also be used as a soil conditioner to improve soil fertility and air permeability and promote the growth and development of crops.

[0008] In the Chinese patent with publication number CN108237006B, a method for preparing ultrafine oyster shell powder is mentioned, which includes oyster shell pretreatment, oyster shell fine powder processing and airflow crushing technology for ultrafine crushing. The present invention screens out the best airflow crushing technology through a large number of experiments, and studies the process parameters affecting the crushing effect. The best process is preferably obtained as follows: feed particle size 100 mesh, feed speed 210V, crushing pressure 0.6MPa, and crushing times 6 times. The present invention processes oyster shells deeply, turning waste into treasure, and the processed oyster shell ultrafine powder has greatly increased surface area and porosity, better solubility, dispersibility, adsorption and chemical activity, and has broad industrial, agricultural and medical value.

[0009] In the above documents, although oyster shells are deeply processed to turn waste into treasure, the surface area and porosity of the processed oyster shell ultrafine powder are greatly increased, the solubility, dispersibility, adsorption and chemical activity are better, and it has broad industrial, agricultural and medical value, but no auxiliary materials are added to the oyster shell powder, which makes the functional effect of the oyster shell powder prepared relatively single, thereby reducing the use effect of the oyster shell powder. For this reason, a talcum powder rich in oyster shell ultrafine powder and a preparation method thereof are proposed.

[0010] The invention adds corn starch, pearl powder, mint and silicon dioxide, mixes the above raw materials and auxiliary materials in a certain proportion, and then grinds them to ensure that the components are fully mixed and the particle size is uniform, which helps to adjust the texture and fluidity of the talcum powder, and at the same time improves the stability and absorbency of the product, increases the skin care effects of the product such as whitening and moisturizing, gives the product a cooling feeling, helps to relieve skin itching and discomfort, can be used as an anti-caking agent, ensures that the product remains in a loose state during use, is not easy to agglomerate, increases the functional effect of the oyster shell powder, and thus improves the use effect of the oyster shell powder;

[0011] And through the effects of antibacterial agents, antioxidants, flavors and thickeners, the growth of microorganisms such as bacteria and fungi may be effectively inhibited, thereby extending the shelf life of the product, and adding a specific fragrance, making the user feel happy and comfortable when applying it. At the same time, the thickener can increase the viscosity of the product, making it easier to apply and evenly distributed on the skin; the thickener also helps to prevent the occurrence of product stratification, precipitation and the like, maintain the uniformity and stability of the product, thereby further increasing the functional effect of the oyster shell powder, improving the use effect of the oyster shell powder, and making the talcum powder prepared from the oyster shell powder easy for users to use. Summary of the invention

[0012] The object of the present invention is to provide a talcum powder rich in oyster shell ultrafine powder and a preparation method thereof, so as to solve the problems raised in the above background technology.

[0013] To achieve the above object, the present invention provides the following technical solutions:

[0014] A talcum powder rich in oyster shell ultrafine powder and a preparation method thereof, comprising:

[0015] Step 1: Pre-treat the oyster shells;

[0016] As can be seen from the above, the operation of the oyster shell pretreatment is: rinse the oyster shells with water, select the oyster shells with regular shape and less surface dirt, then rinse the selected oyster shells with water again, and after drying naturally, grind off the outer impurities for standby use.

[0017] Step 2: Processing the pre-treated oyster shells into fine powder;

[0018] From the above, it can be seen that the processing operation of the oyster shell fine powder is: the pretreated oyster shell is broken into fine pieces, then crushed into coarse powder with a grinder, placed in a drying oven for drying, taken out and sieved, and the mesh number of the crushed oyster shell fine powder screen is 60 mesh, 80 mesh and 100 mesh.

[0019] Step 3: Ultrafinely pulverizing the oyster shells after fine powder processing;

[0020] As can be seen from the above, the operation of ultrafine grinding of oyster shells is as follows: fine powder of oyster shells is ultrafinely ground by airflow grinding technology;

[0021] The present invention further specifically describes that the airflow pulverizing equipment is a MC-AO type desktop micro airflow pulverizer, the airflow pulverizing equipment has 6 pulverizing times, the feed speed of the airflow pulverizing equipment is 210V, and the pulverizing pressure of the airflow pulverizing equipment is 0.6MPa.

[0022] Step 4: After the oyster shells are ultra-finely crushed, additives and auxiliary agents are added into the shells according to a certain proportion;

[0023] The present invention further specifically describes that the auxiliary agents added after the oyster shell is ultrafinely crushed are corn starch, pearl powder and mint, and the additives added after the oyster shell is ultrafinely crushed are antibacterial agents, antioxidants, flavors and thickeners;

[0024] From the above, it can be seen that adding corn starch, pearl powder, mint and silicon dioxide to prepare talcum powder from oyster shell ultrafine powder has the following benefits:

[0025] Corn starch has good hygroscopicity and can help absorb excess moisture and sweat on the skin, keeping the skin dry and comfortable; the fine texture of corn starch can make the powder of talcum powder more delicate and smooth, and will not cause a rough feeling on the skin when used;

[0026] Pearl powder is rich in various amino acids and trace elements, and has beauty effects such as whitening, lightening spots, and anti-wrinkle. Adding it to talcum powder can enhance the beauty effect of the product and make the skin smoother and more delicate. The nutrients in pearl powder can nourish the skin, promote skin metabolism, and help the skin stay healthy and energetic.

[0027] Mint has a cooling and refreshing effect, which can add a cool feeling to talcum powder and bring a comfortable experience when using it; mint also has a soothing effect on the skin. For people with sensitive skin or prone to redness, swelling, itching and other problems, using talcum powder containing mint can relieve these discomforts;

[0028] As a glidant, silicon dioxide can significantly improve the fluidity of talcum powder, making it smoother and less prone to clogging during use; the addition of silicon dioxide can also prevent talcum powder from agglomerating during storage, maintaining the stability and quality of the product.

[0029] In summary, by adding corn starch, pearl powder, mint and silicon dioxide, the above raw materials and auxiliary materials are mixed in a certain proportion and then ground to ensure that the ingredients are fully mixed and the particle size is uniform, which helps to adjust the texture and fluidity of the talcum powder, while improving the stability and absorbency of the product, increasing the whitening, moisturizing and other skin care effects of the product, giving the product a cooling feeling, helping to relieve skin itching and discomfort, and can be used as an anti-caking agent to ensure that the product remains loose during use and is not easy to clump, thereby increasing the functional effect of the oyster shell powder, thereby improving the use effect of the oyster shell powder;

[0030] Adding antimicrobial agents, antioxidants, flavors and thickeners to the talcum powder prepared from superfine oyster shell powder has the following benefits:

[0031] Antimicrobial agents can effectively inhibit the growth of microorganisms such as bacteria and fungi, thereby extending the shelf life of products and preventing problems such as skin infections or allergies caused by microbial contamination. By reducing the number of microorganisms, antimicrobial agents help improve the overall safety of products, making them more suitable for use on sensitive skin or infants.

[0032] Antioxidants can remove free radicals and prevent oxidation reactions of oils, proteins and other ingredients in products, thereby maintaining product stability and quality. By preventing oxidation, antioxidants help extend the shelf life of products and reduce deterioration or failure caused by oxidation.

[0033] Fragrances can add a specific scent to a product, making the user feel pleasant and comfortable when applying it; attractive scents can make a product more appealing and increase consumers’ willingness to buy;

[0034] Thickeners can increase the viscosity of the product, making it easier to apply and evenly distribute on the skin; thickeners also help prevent product stratification and sedimentation, thereby maintaining product uniformity and stability;

[0035] In summary, through the effects of antibacterial agents, antioxidants, flavors and thickeners, the growth of microorganisms such as bacteria and fungi can be effectively inhibited, thereby extending the shelf life of the product, and adding a specific fragrance, making the user feel happy and comfortable when applying it. At the same time, the thickener can increase the viscosity of the product, making it easier to apply and evenly distributed on the skin; the thickener also helps to prevent the occurrence of product stratification, precipitation and the like, maintain the uniformity and stability of the product, thereby further increasing the functional effect of the oyster shell powder, improving the use effect of the oyster shell powder, and making the talcum powder prepared from the oyster shell powder easy for users to use.

[0036] By preparing oyster shell powder into talcum powder, the following market demands and economic benefits are achieved:

[0037] Diversified application scenarios: Oyster shell ultrafine powder talcum powder not only has the basic functions of traditional talcum powder, such as moisture absorption, antiperspirant, deodorant, etc., but also has additional effects such as antibacterial and anti-inflammatory due to its unique ingredients. These characteristics make oyster shell ultrafine powder talcum powder have a wide market demand in many fields such as maternal and child care and adult care;
