The invention discloses a device for assisting in processing of biological pharmacy. The device comprises a pot, a pot cover, a medicine bag, a positioning room, a driving component, flow guiding holes, a disassembly and assembly structure and a turbulent flow device, wherein the pot cover is matched with the pot body and used for sealing an opening in the upper portion of the pot body; the medicine bag is used for containing medicine and made of filter cloth; the positioning room is rotatably arranged inside the pot, and performs positioning operation on the medicine bag during medicine decocting; the driving component is used for driving the positioning room to rotate; the flow guiding holes are formed in the side wall of the positioning room and used for medium circulating in the pot body when the positioning room rotates; the disassembly and assembly structure is used for detachably connecting the medicine bag to the pot cover; the turbulent flow device is used for stirring media in the positioning room when the positioning room rotates, so that the media form a turbulent flow state. By arranging the turbulent flow device, when the positioning room rotates, the turbulent flow state can be formed inside the positioning room, medicinal liquid is mixed uniformly, medicinal materials are easier to decoct completely, it is guaranteed that the concentration of the medicinal liquid in the pot is high, and the quality of medicine prepared in the late period is high.
