Problems solved by technology

[0016] Since the nacre is located in the innermost layer of the shell, in order to obtain the nacre, the stratum corneum and the prismatic layer must be removed first. Since the nacre is very thin, it is not only time-consuming, laborious and expensive to remove by physical methods, but also easily destroys the organic matter contained in it. Therefore, it is particularly important to adopt a new type of efficient, simple and cheap method to obtain nacre, which is also one of the purposes of the patent of the present invention
[0017] The raw material cost of nacre powder itself is very low. In order to obtain nacre, impurities such as the cuticle on the outside of the shell and the prismatic layer in the middle (the calcium carbonate is calcite structure) must be removed. The most ideal method is to use physical methods to remove the outer layer and The middle layer is used as a raw material, but doing so will increase the processing cost of pearl layer powder a lot, so the actual market situation is: only use strong alkaline substances such as NaOH to remove the outer cuticle and directly crush it into powder. The inherent natural minerals, nutrients and trace elements of the nacre are easily destroyed, and the removal rate of impurities such as non-aragonite calcium carbonate, cuticle, prismatic layer, outer verrucous and algae pigments is low. Heavy metal residues are large, the medicinal value is greatly reduced, and clinical drug safety problems are prone to occur

Embodiment 1

[0040] 21.2 kg of variegated abalone shells were placed in an extraction tank, and 10 mol / L hydrochloric acid solution with a weight ratio of 3 times was added, and acid-washed at room temperature to remove non-aragonite-structured calcium carbonate, cuticle, prism layer, outer shell, etc. Impurities such as verruca and algae pigments, after 15 minutes, when no carbon dioxide bubbles are generated, let stand for 5 minutes and then separate the solid and liquid, wash the separated pearl layer with water until the washing liquid is neutral, After drying and then drying, the nacre raw material is obtained, which has the original pearl luster of the inner layer of the variegated abalone shell, and the shell shape integrity rate is 90.8%, retaining the original natural minerals, keratin and trace elements of the nacre . The pearl layer is further baked at a high temperature of 120-150°C. When the surface is yellow and there is a crackling sound, it is quickly cooled to 60-70°C, mec...

Embodiment 2

[0042] 13.9 kg of wrinkled abalone shells were placed in an extraction tank, and 6 mol / L nitric acid solution with a weight ratio of 5 times was added, and acid-washed at 45°C to remove non-aragonite calcium carbonate, cuticle, prism layer, Impurities such as warts and algae pigments in the outer layer, when no carbon dioxide bubbles are generated, let stand for 12 minutes before solid-liquid separation, and wash the separated pearl layer with water until the washing liquid is neutral, then drain , put it in a ball mill cylinder, add appropriate amount of distilled water, ball mill it into powder, put it in a square pan and spread it evenly, bake it at 110-120°C until dry, cool it to room temperature, put it in a vibrating kneader to vibrate and pulverize, and collect it by classification. Ultrafine nacre powder with a fineness of 600 mesh can be obtained. After testing, the nacre aragonite-type calcium carbonate content is 94.8%, and the impurity removal rate is 92.5%.

Embodiment 3

[0044] 6.1 kg of Australian abalone shells are placed in the extraction tank, using 10 times the weight ratio of acetic acid aqueous solution, and at no lower than room temperature, reflux to remove non-aragonite calcium carbonate, cuticle, prismatic layer, and outer warts in the abalone shell During the extraction process, the concentration of hydrogen ions in the system should not be lower than 2 mol / L. When no more carbon dioxide bubbles are generated, the solid-liquid separation will be allowed to stand for 20 minutes, and the separated nacre After washing with water until the washing liquid is neutral, it is dried, crushed by high temperature and high pressure, and then crushed in a jet mill and collected by classification to obtain superfine nacre powder with a fineness of 1000 mesh. After testing, the nacre aragonite-type calcium carbonate content is 96.2%, and the impurity removal rate is 91.1%. The superfine nacre powder can be further processed into nano nacre powder...

Abstract

The invention discloses abalone shell pearl layer powder and a processing method of the abalone pearl layer powder. Abalone shell is used as a raw material, abalone shell pearl layer with an aragonite structure is prepared through a crushing process, the prepared pearl layer powder has the characteristics of solubility in acid, insolubility in acid and insolubility in water, and the content of aragonite calcium carbonate is equal or greater than 94 percent; the prepared pearl layer powder has the original nacreous luster of the inner layer of the abalone shell, and the removal rate of impurities such as calcium carbonate with a non-aragonite structure, cuticle, prismatic-calaite layers, algal pigment and the like is not lower than 91 percent. According to the invention, under a lower temperature condition, an acid solution with lower concentration is adopted, the impurities can be removed within short time through acid pickling, a medicinal composition pearl layer is retained to a great extent, superfine grade and nanoscale pearl layer powder can be further obtained through smashing, the conception is novel, the raw materials are rich, the production efficiency is high, the production cost is low, the processing technology is simple, green environmental protection is achieved, the implementation is convenient, the abalone shell pearl layer powder conforms to industrial development trend of traditional Chinese medicine modernization and internationalization, and a greater generalization performance is achieved.

Description

technical field [0001] The invention specifically relates to abalone shell pearl layer powder and a processing method thereof, belonging to the field of high-value utilization of marine shell resources and green processing of fine chemicals. Background technique [0002] Not only is China rich in pearl resources, accounting for 95% of the world's output, but the Chinese have a long tradition of using pearls, and the medicinal use of pearls has a history of more than 2,000 years in China. "Famous Doctors" in the Three Kingdoms, "Compendium of Materia Medica" in the Liang Dynasty, "Haiyao Materia Medica" in the Tang Dynasty, "Kaibao Materia Medica" in the Song Dynasty, "Compendium of Materia Medica" in the Ming Dynasty, "Lei Gong Medicine Nature Fu" in the Qing Dynasty, etc. There are 19 kinds of ancient medical books, all of which have clear records on the curative effect of pearls. Liang Dynasty Tao Hongjing's "Compendium of Materia Medica" believes that pearls "have the fu...
