在显微镜下检视酵母粉有两种形状:一种是不规则的不定形粉末(如广东海康及江门酵母),另一种是球形颗粒(如武汉酵母)。因酵母粉质松且有弹性,不易直接使粉末(或颗粒)间产生足够的内聚力而压紧,故大多数厂家采取湿法制粒,在制粒时加入大量的糖粉及碳酸钙等,使仅含干酵母0.3g的片剂片重达0.5g以上。即使如此,如用球形颗粒状原料生产的片剂,硬度仍不够好。为此,我们对不同形状的原料采用不同方法制粒压片,效果比较满意, There are two forms of yeast powder under the microscope: one is irregular amorphous powder (such as Guangdong Haikang and Jiangmen yeast), and the other is spherical granules (such as Wuhan yeast). Due to the yeast silty pine and flexible, not easy to make the powder (or particles) to produce sufficient cohesion and compact, so most manufacturers take wet granulation, adding a lot of sugar and calcium carbonate in the granulation, so that 0.3g dry yeast tablets only weigh 0.5g or more. Even so, such as tablets made from spherical particulate material, the hardness is not good enough. To this end, we use different methods of different shapes of raw materials granulation tablets, the effect is more satisfactory,
