The invention discloses a stirring mixing apparatus capable of improving the stirring effect. The apparatus include a mixing tank, an observation window is fixedly installed at the outer surface of the front end of the mixing tank, an upper cover is fixedly mounted at the external surface of the upper end of the mixing tank, a motor is fixedly mounted at the external surface of the upper cover side, a power meter is fixedly mounted at the external surface of the front end of the motor, and a feed port, a sampling port and a cooling water inlet are fixedly mounted at the external surface of themixing tank side, wherein the feed port is located above the sampling port, and the cooling water inlet is located below the sampling port. The stirring mixing apparatus is provided with a temperature sensor, a latch and bubblers. The temperature during stirring can be gotten in time, blocks can be easily pulverized, and stirring becomes uniform. Bubbles produced during stirring are broken, so that pores in a mixture obtained from stirring are prevented. The apparatus has bright application prospects.
