  • Patent number: 8021520
    Abstract: The invention relates to a device and method for preparing liquid from solid materials such as medicinal materials. It includes liquid and materials for preparing the liquid at the beginning and the end of the process. The device uses a steam generator, an intermediate switch valve and a material chamber, which are connected sequentially with pipes, and further includes an outlet pipe, which is at the bottom of the material chamber. The method involves the steps of: distillation and absorption; immersion; and repetition. The device and method for preparing liquid alternates the distillation and immersion steps, which reduces harmful substance in the prepared liquid that would otherwise occur by conventional methods. The method not only extracts soluble effective matter, but also reduces loss of volatile effective matter. Ultimately, the method makes the steps for preparing liquid simple and clear, and it can prepare liquid quantitatively, effectively and without pasty and shrinkable characteristics.

  • Publication number: 20070017793
    Abstract: The present invention relates to a device and method for preparing liquid from solid materials such as medicinal materials. It comprises preparing materials for preparing liquid and liquid at the beginning, and obtaining prepared liquid at the end. Wherein it uses steam generator 2, intermediate switch valve 6 and material chamber 8, which is protruded into by outlet pipe 10 which is at the bottom of material chamber 8. It further comprises steps as follows: distillation and absorption; immersion; repetition. The device and method for preparing liquid adopts the way of repeating the distillation and dip alternately, reducing harmful substance in preparing liquid by conventional methods. If not only extracts soluble effective matter, but also reducing the loss of volatile effective matter.
