The invention discloses a mixed flow stirring soybean milk machine which comprises a base, an outer barrel body, a barrel body fixing plate, a barrel cover and a stirring rotary disc. A heat insulation barrel is arranged on the inner side wall of the outer barrel body. A plurality of circles of heating pipes are arranged inside the heat insulation barrel. The inner sides of the heating pipes are provided with a heating barrel in a tight contact mode. The bottoms of the outer barrel body, the heat insulation barrel and the heating barrel are fixed to the base through the barrel body fixing plate. An outer rotary sleeve shaft penetrates through the center of the barrel body fixing plate. The portion, penetrating through the barrel body fixing plate, of the outer rotary sleeve shaft is sleeved with a sealing ring. An inner rotary shaft penetrates into the outer rotary sleeve shaft. The bottom of the outer rotary sleeve shaft and the bottom of the inner rotary shaft are provided with an outer rotary sleeve shaft driving gear and an inner rotary shaft driving gear. During smashing and stirring, disordered turbulent flow is formed, and the smashing and stirring effect and efficiency are improved.
