Abstract

This invention discloses a multifunctional extraction tank for preparing Shiwei Fuzheng Granules, belonging to the field of extraction tank technology. It includes a tank body, a lower cover, and a feeding mechanism. The tank body is equipped with a stirring device. The lower cover is hinged to the tank body, and an automatic closing mechanism is provided between the lower cover and the tank body. A first filter section is provided at the lower part of the tank body, arranged circumferentially along the tank body. The first filter section includes, from the inside out, a first filter layer, a second filter layer, and a filter chamber. The filter chamber is connected to the stirring device through a drainage pipe. The stirring device includes a stirring motor and a stirring rod. The stirring rod has a hollow structure and multiple water outlets, and is connected to the drainage pipe. The lower cover has a steam injection port. This invention, through the stirring rod and the first filter section, enables rapid and uniform heating during the stirring process, easily meeting various requirements of the extraction process.
