High-temperature and high-pressure steam entering through the steam feeding port 201 distills, disinfects, sterilizes, and softens the coarse fibers of the pulverized straw, and at the same time, the spiral conveying mechanism 207 is driven to rotate by the continuous distiller motor 205 to complete the continuous distillation and conveying of the pulverized straw. The distilled straw is laid flat on the belt conveyor 3 through the distilled straw discharge port 204 for conveying and airing to dissipate heat, and finally is conveyed into the mixing blender 4. The mixing blender motor 401 drives the mixing blender stirring mechanism 406 to rotate to stir the distilled straw, and at the same time, the bran powder sprayer 403 and the saccharifying enzyme liquid sprayer 404 spray bran powder and saccharifying enzyme liquid into the mixing blender shell 405, which are fully stirred and discharged after reaching a certain amount to be stacked and fermented.
