Fermentation tank for cosmetic production

The fermentation tank comprises a fermentation tank outer wall, a condensate water outlet is fixedly connected to the left side of the bottom end of the fermentation tank outer wall, a view frame opening outer wall is fixedly connected to the right side of the upper end of the fermentation tank outer wall, and a connecting shaft is fixedly connected to the left side of the view frame opening outer wall; the lower end of the outer wall of the fermentation tank is fixedly connected with a discharge port, and the left side of the upper end of the outer wall of the fermentation tank is fixedly connected with a feed port outer wall. According to the cosmetic fermentation device, firstly, when cosmetics are fermented, the output end of a motor can rotate to drive a rotating rod to rotate, at the moment, a first gear on the rotating rod and a second gear on a sub-rotating sleeve can rotate oppositely due to meshing connection, and therefore a first stirring frame and a second stirring frame are driven to rotate reve
