[0014] The beneficial effects of this application are: 1. The mixing device for the expanding agent provided uses a spray mechanism to pressurize and blow air to the bottom material upwards, and then the mixing blades are rotated by a motor to stir the mixture, so that the mixture is mixed evenly in all aspects and the mixing rate is improved; 2. After the material is discharged, the spray mechanism can be used to blow off the material attached to the mixing cylinder, thereby improving the discharge rate and facilitating cleaning.
