The invention discloses a stirring, cooling and extruding machine.The stirring, cooling and extruding machine comprises a machine frame (7), a machine body (5) with a feeding hopper (6), a stirring shaft (2), screw blades (3), a coupling (8) and a speed adjusting motor (9), and is characterized in that condenser pipes (4) are wound around on the outer surface of a stirring and extruding section of the machine body (5), and the condenser pipes (4) are sleeved with a thermal insulation pipe (1).As the stirring and extruding section of the machine body is cooled through the condenser pipes, the speed adjusting motor is started, materials are added, the rotating speed of the speed adjusting motor is adjusted, and the temperature of the materials discharged from the discharging end is close to the frost point.As the temperature is low, when the materials enter a homogenizing device to be processed, the quality of the final product can not be influenced by the over-high temperature.By means of the stirring, cooling and extruding machine, the aims that the materials can be effectively mixed to be even, the temperature of the materials is reduced, and the structure is simple are completely achieved.
