The invention discloses a production device and method for a concrete polymer modifier. The production device comprises a mixing barrel, a refrigeration compressor, a mixing shaft, a box body, a plurality of groups of inner blades, a plurality of outer blades, and a plurality of lower blades and a power source. The mixing barrel is located on the box body, a motor is arranged in the box body, the box body is composed of an inner layer and an outer layer, a plurality of refrigerating pipes are arranged between the inner layer and the outer layer, the refrigeration pipes are connected with the refrigeration compressor, a mixing barrel cover is arranged on an opening in the top of the box body, a discharging port is formed in the side face of the bottom of the mixing barrel, and a discharging valve is arranged at the position of the discharging port. The mixing shaft is of a hollow structure, a heating wire is arranged in the mixing shaft, and a display, a power switch, a rotating speed regulating button for controlling the rotating speed of an output shaft of the motor, and a temperature regulating button for controlling the heating wire and the refrigeration compressor are arranged on the side face of the box body. A temperature sensor is arranged in the mixing barrel. By means of the production device and method for the concrete polymer modifier, the concrete polymer modifier can be mixed uniform and does not stick to the inner wall of the mixing barrel.
