The utility model discloses a bast fiber biological degumming device which comprises a tank body and a dissolution assisting pipeline, a bast fiber cage is placed in the tank body, a micropore distributor is arranged below the bast fiber cage, the micropore distributor is communicated with an air pipe and is made of porous ceramic materials, the dissolution assisting pipeline is arranged on the outer side of the tank body, and the dissolution assisting pipeline is communicated with the air pipe. One end of the hydrotropy pipeline is communicated with the lower part of the micropore distributor, the other end of the hydrotropy pipeline is communicated with the upper part of the hemp cage, and a tank cover is arranged at the top end of the tank body. Compared with the prior art, caustic soda and concentrated sulfuric acid do not need to be added, the degumming process is simple, the condition is mild, the inorganic and organic pollutant treatment load is reduced by more than 80%, the microporous distributor made of the porous ceramic material is matched with the hydrotropy pipeline, the bast fiber biological degumming speed can be increased, the degumming is uniform, the degumming effect is good, and the cost is low. And the processing cost is reduced by about 20%.
