  • Patent number: 11013694
    Abstract: The present invention relates to a preparation method for a traditional Chinese medicine drop pill and a traditional Chinese medicine micro drop pill prepared by using the method, and in particular, the present invention relates to a micro drop pill preparation method with high drug-loading capacity, simple preparation process and high production rate and a micro drop pill prepared by using the method. Specially, The drop pill preparation method used comprises the following steps: (1) material melting step: heat melting a medicine and a drop pill matrix to obtain a molten medicine liquid; (2) dropping step: delivering the molten medicine liquid to a dripper, and acquiring medicine drops of the molten medicine liquid by means of vibration dropping; and, (3) condensation step: cooling the medicine drops with a cooling gas to obtain micro drop pills.

  • Patent number: 10918575
    Abstract: An intelligent dripping pill machine for continuous liquid solidification comprises: a feeding device (1), a material combining device (2), a homogenizing device (3), a dripping device (4) and a de-oiling device (5) sequentially connected via a transmission channel. The intelligent dripping pill machine removes, via high-speed centrifugation, a cooling liquid attached to dripping pills, and each component device is connected compactly, thereby achieving a continuous manufacturing operation, and reducing an occupied space of the devices as a whole while ensuring the yield of the dripping pills.
