The invention discloses a sequencing batch ramie decorticator. The sequencing batch ramie decorticator comprises a rotary ramie stalk conveying unit connected with a machine frame, a ramie stalk green bark and colloid scraping unit, a ramie bone crushing unit, a ramie bone, bark and colloid conveying and collecting unit, a ramie stalk lifting unit, a ramie stalk clamping unit and a ramie bark fiber cutting and recovering unit. The cylinder body of a lifting hydraulic cylinder in the ramie stalk lifting unit is connected to a protruded suspension beam of the rotating board in the rotary ramie stalk conveying unit through a flange, the flange on the piston push rod of the lifting hydraulic cylinder is connected with a rotating board of the ramie stalk clamping unit, and the piston push rod moves along with a guide bar of the ramie stalk lifting unit to drive clamps of the ramie stalk clamping unit to move up and down; the ramie bark fiber cutting and recovering unit is arranged on the left of the ramie stalk green bark and colloid scraping unit, the ramie bone crushing unit and the ramie bone, bark and colloid conveying and collecting unit. The sequencing batch ramie decorticator achieves automated operation of bone removal, green bark removal and colloid removal and has the advantages of good use effects, high practicality and the like.
