The invention belongs to the technical field of sterilization equipment, and particularly relates to a sterilization device and method for solid high-fiber materials. The sterilization device includes a twin-screw extruder composed of an extrusion unit and a feeding unit arranged above the extrusion unit; the extrusion unit comprises a rotating shaft and multiple screws sleeved on the rotating shaft. A thinning ring is arranged between two adjacent screws close to the extrusion motor, and a homogenizing ring is arranged between two adjacent screws far from the extrusion motor. Both the thinning ring and the homogenizing ring are hollow truncated cones. The left side of the homogenizing ring is designed with rounded corners, and a plurality of horizontally extending notches are evenly distributed along the circumferential direction. The feeding unit consists of a feeding motor, a feeding hopper and a feeding screw. The invention has a clever design, convenient operation and simple control, realizing continuous instant sterilization of solid high-fiber materials. It boasts wide material adaptability, high continuity, high production efficiency, uniform sterilization and adjustable and controllable sterilization conditions.
