A feeding port 11 and a heating device (not shown in the figure) are arranged on the raw material storage tank 1. The dry matter concentration of the erythritol microbial residue waste liquid is 25-30%. In order to prevent the erythritol microbial residue waste liquid stored in the raw material storage tank 1 from not fermenting, the temperature of the raw material storage tank 1 needs to be controlled at 50-60℃, and the heating device needs to be arranged.

[0014] The buffer tank 2 controls the liquid level, and the material pump 3 is used to transport the preheated erythritol microbial residue waste liquid to the steam drum 4.

[0015] A steam inlet 41 is arranged on the steam drum 4. The steam drum 4 is used to evaporate the erythritol microbial residue waste liquid into erythritol microbial residue. The size of the steam drum 4 is Ф2.5m*4m, the steam pressure is 0.4-0.5MPa, and the preheating temperature is above 100℃.

[0016] The screw conveyor 5 is used to transport the erythritol microbial residue to the pulverizer 6 for pulverization, and the cyclone separator 7 is used to separate the pulverized material obtained by the pulverizer 6 to obtain erythritol microbial residue powder products. The power of the pulverizer is 7.5kW, the current is 15.4A, the voltage is 380V, and the rotating speed is 1460r / min.

[0017] A waste gas treatment device 8 is arranged on the steam drum 4, which is used to purify the waste gas generated during the operation of the steam drum 4 to prevent the waste gas from polluting the environment.
