中药超微粉碎对物料粉末性质影响有哪些?

超微粉碎是指用机械或流膂力学方法对直径>3 mm~10~(-25)μm的物料颗粒中止粉碎,以抑制固体内部粘聚力的操作技术。超微粉碎机一款超小型研磨超微粉碎机,适宜大学实验室、工厂实验室、药店、中医院以及家庭做精细研磨运用,可随身携带。弘荃系列机型可普遍用于中药、西药、农药、生物、化装品、食品、饲料、化工、陶瓷、冶金矿物等多行业干性物料的超微粉碎需求。特别关于纤维性(如中草药、灵芝等)、高韧性(动物角类、棉花等)、高硬度(如金刚石、陶瓷等)物料的粉碎效果更为圆满。
Ultrafine comminution refers to the operation technology of suspending the comminution of material particles with diameter > 3 mm~10-25 um by mechanical or fluid mechanics method to restrain the cohesion inside the solid. Ultra-miniature grinder Ultra-miniature grinder, suitable for University laboratories, factory laboratories, pharmacies, traditional Chinese medicine hospitals and families to do fine grinding applications, can be carried with you. Hongquan series machines can be widely used for ultra-micro grinding of dry materials in traditional Chinese medicine, western medicine, pesticides, biology, cosmetics, food, feed, chemical industry, ceramics, metallurgical minerals and other industries. Particularly, the crushing effect of fibrous (such as Chinese herbal medicine, Ganoderma lucidum, etc.), high toughness (animal horns, cotton, etc.), high hardness (such as diamond, ceramics, etc.) materials is more satisfactory.
在一定程度上,超微粉碎的条件会影响到粉体的物理性能,不同粒径的超微粉体的物理性能也会有所不同,包括粉体的活动性、持水性、收缩力、体积密度等。本公司特制中药超微粉碎机对黄芪、白附子等药材中止超微粉碎后,对黄芪、白附子的粉末性有何影响?
To a certain extent, the conditions of ultrafine comminution will affect the physical properties of powders, and the physical properties of ultrafine powders with different particle sizes will also vary, including the activity, water holding capacity, shrinkage force and volume density of powders. What effect does our company's special ultra-fine crusher have on the powder properties of Astragalus membranaceus and aconite Alba after the suspension of ultra-fine crushing of Astragalus membranaceus and aconite alba?
中药超细粉碎机
(1)对黄芪、乌头中止超微粉碎后,对黄芪、白附子的粉末性有何影响1.将黄芪超微粉分别以0.038、0.048、0.074、0.124和0.150 mm中止选择,发现黄芪超微粉具有良好的活动性、吸附性和总黄酮的溶出度。因此,选择出孔径为0.038 mm的黄芪体积聚积分布率(Va)作为优化黄芪超微粉碎工艺的指标。分别调查了破碎温度、破碎时间和物料含水量对Va的影响。应用DesignExpert软件对实验数据中止回归分析,得到了磨削温度、破碎时间和物料含水量与Va的二次多元回归方程。结果标明,影响要素大小次第为物料含水量>破碎时间>破碎温度。在相互作用要素的影响分析中,粉碎时间和粉碎温度的交互作用对黄芪超微粉的影响为显著。根据理论情况,当破碎温度为-20℃,破碎时间为20.5min时,物料含水量为6.7%。用0.038 mm选择得到的黄芪超微粉Va高达86.9%。
(1) After the suspension of ultrafine comminution of Astragalus membranaceus and aconitum, how does it affect the powder properties of Astragalus membranaceus and Radix Aconiti baifuzi? Therefore, the volume aggregation distribution rate (Va) of Astragalus membranaceus with pore size of 0.038 mm was selected as the index to optimize the ultrafine grinding process of Astragalus membranaceus. The effects of crushing temperature, crushing time and material moisture content on Va were investigated. By using DesignExpert software to stop regression analysis of experimental data, the quadratic multiple regression equation of grinding temperature, crushing time and material moisture content with Va was obtained. The results showed that the influencing factors were water content > crushing time > crushing temperature. In the analysis of interaction factors, the interaction of grinding time and grinding temperature has a significant effect on the ultrafine powder of Astragalus membranaceus. According to the theory, when the crushing temperature is - 20 C and the crushing time is 20.5 min, the moisture content of the material is 6.7%. Va of Astragalus membranaceus ultrafine powder selected by 0.038 mm was up to 86.9%.
这一系列实验不只标明超微磨削能显著进步物料的均匀性、活动性、持水性、收缩力和体积密度以及有效成分的溶解速率,而且物料含水量对Va的影响大,其次是磨削时间,第三是磨削温度。这些要素可应用于超微磨削工艺的优化、分析和预测。2.研讨了超微粉碎对白附子中草酸钙针晶形态和数量的影响。在光学显微镜下观察了草酸钙晶体的形貌、数量和存在方式。
This series of experiments not only indicate that ultra-micro grinding can significantly improve the uniformity, mobility, water holding capacity, shrinkage force and volume density of materials, as well as the dissolution rate of effective components, but also that the moisture content of materials has a great influence on Va, followed by grinding time and grinding temperature. These factors can be applied to the optimization, analysis and prediction of Ultra-micro grinding process. 2. The effects of ultrafine comminution on the morphology and quantity of calcium oxalate needle crystal in Aconitum Alba were studied. The morphology, quantity and existing mode of calcium oxalate crystal were observed under optical microscope.
将不同粒径的普通粉体、不同粒径的超微粉体及明矾粉体置于光学显微镜下,观察草酸钙晶体的形貌、数量及存在方式。从形貌上看,在常规粉料中可以观察到完好的或少量破碎的草酸钙晶体。固然晶体是横向破碎的,但它仍然是一个圆柱体,可以看到晶体上的凹槽和尖尖。在超微粉白附子样品中,扫描电镜观察到草酸钙针晶的纵向断裂,晶体普通为扁平长方体,无草酸钙针晶柱体和针尖。
The morphology, quantity and existing mode of calcium oxalate crystals were observed by placing ordinary powders with different particle sizes, ultrafine powders with different particle sizes and alum powders under optical microscope. From the morphology, intact or a small amount of broken calcium oxalate crystals can be observed in the conventional powder. Although the crystal is transversely fragmented, it is still a cylinder, with grooves and sharp points visible on the crystal. Longitudinal fracture of calcium oxalate needle crystals was observed by scanning electron microscopy in ultrafine powder aconite samples. The crystals were generally flat cuboids, without calcium oxalate needle cylinders and needle tips.
在数量上,随着粉末数量的增加,草酸钙针状晶体及其单位体积碎片的数量减少。在存在方式下,在0.150 mm通孔药物筛的常规粉碎样品中,在完好的粘液细胞中经常发现针晶,针晶分散在针束和针晶中以坚持完好的晶体外形。在常规粉碎性通孔0.074 mm药物筛中,很难看到粘液细胞,且草酸钙针状晶体大多散在。超微粉碎孔径为0.025.5%,粒径为0.0 38 mm的草酸钙针状晶体碎片较分散。传统明矾产品的粉末分散在针束和针晶中。其中,超微粉碎粉体和明矾粉体的共同之处在于它们都能减少草酸钙的数量。
In terms of quantity, with the increase of powder quantity, the number of acicular crystals of calcium oxalate and its unit volume debris decreases. Needle crystals are often found in the well-functioning mucous cells in the routine crushed samples of 0.150 mm through-hole drug sieves. Needle crystals are dispersed in the needle bundles and needle crystals to adhere to the perfect crystal shape. It is difficult to see mucous cells in the conventional comminuted through-hole 0.074 mm drug sieve, and needle-like crystals of calcium oxalate are mostly scattered. The acicular crystal fragments of calcium oxalate with a diameter of 0.025.5% and a diameter of 0.038 mm were dispersed. The powder of traditional alum products is dispersed in needle bundles and needle crystals. Among them, the common feature of ultrafine grinding powder and alum powder is that they can reduce the amount of calcium oxalate.
