[0027] The specific implementation of the mixer set 1 is as follows: The formula amount of soap base particles is quantitatively conveyed to the second discharge chute 7 by the raw material quantitative conveying set and enters the mixer set 1, and the compounded essential oil prepared by the compounded essential oil preparation set 5 is quantitatively conveyed to the first discharge chute 6 and is discharged to the mixer set 1 through the flow guide 14 in the first discharge chute 6. The soap base particles falling from the second discharge chute 7 first fall onto the first layer of the rotating discharge hopper 112, which rotates under the drive of the drive set 4, and the soap base particles on it rotate and contact the fixed or rotating flow guide 14 under the action of centrifugal force, taking the compounded essential oil flowing down the flow guide 14 and falling onto the first layer of the fixed discharge hopper 111. The first layer of the fixed discharge hopper 111 is arranged obliquely, and the soap base particles are discharged along the slope of the first layer of the fixed discharge hopper 111 under the influence of their own gravity, again contacting the flow guide 14 to take the compounded essential oil, and then the soap base particles with the compounded essential oil reach the feeding screw 114 through the discharge port of the first layer of the fixed discharge hopper 111.
