Surrounding type mixing and expanding culture medium preparation machine

The invention discloses a surrounding type mixing and expanding culture medium preparation machine. The surrounding type mixing and expanding culture medium preparation machine structurally comprisesan equipment main body, a control panel, a culture tank, a reverse mixing device and an injection hole, beneficial effects are as follows: an arranged scrub structure is utilized, under the action ofmovable contact between a triangular cone and a circulation hole, movable friction processing is carried out on incompletely dissolved particles attached to the surface of the circulation hole duringrotation; therefore, the incompletely dissolved particles are completely dissolved; culture water and materials are uniformly mixed; and normal preparation of a culture medium is ensured. By means ofan arranged stirring structure, when poured auxiliary solutions rotate in a vortex mode and are collected in a centralized mode from top to bottom, dispersion and permeation are conducted on the solutions flowing in the vortex m
