    • A stirring blade unit includes a perforated cylinder formed around the an internal stirring blade so as to be rotated together with the stirring shaft. The perforated cylinder has perforations which are approximately 30 to 50% of the area of the top and bottom surface of the perforated cylinder. The internal stirring blade unit uses a discharge type stirring blade unit used for gas-liquid mixing of a general fermentation tank. Thus, the gas-liquid flow discharged from the blade unit in the horizontal direction hits the perforated cylinder formed around the blade unit certainly. Due to this hitting of the gas-liquid flow against the perforated cylinder, the pressure of the flow is changed significantly to refine the gas bubbles so that the gas absorption property is improved. The stirring blade unit is suitable for gas-liquid mixing necessary for such as, fermentation, aeration, and reaction (hydrogenation and oxidation) tanks. The gas-liquid mixing blade unit can absorbs gas efficiently and thus, reduces both the manufacturing cost and installation space.
    • 搅拌叶片单元包括围绕内部搅拌叶片形成的穿孔圆筒,以便与搅拌轴一起旋转。 穿孔圆筒具有穿孔,其穿孔面积是穿孔圆筒顶面和底面面积的约30%至50%。 内部搅拌叶片单元使用用于一般发酵罐的气液混合的排出型搅拌叶片单元。 因此,从叶片单元沿水平方向排出的气液流肯定地撞击形成在叶片单元周围的多孔圆筒。 由于气体 - 液体流向多孔圆柱体的撞击,流动的压力被显着改变以改善气泡,从而提高了气体吸收性能。 搅拌叶片单元适用于发酵,通气和反应(氢化和氧化)罐所需的气液混合。 气液混合叶片单元可以有效吸收气体,从而降低制造成本和安装空间。
