[0002] During the production and processing of gray board, steam is required to heat the gray board slurry. The specific processing flow is that steam enters the interior of a container containing the gray board slurry through a pipe for processing. Steam heating can not only increase the temperature but also replenish moisture. However, in the existing gray board slurry steam heating method, after the steam enters the interior of the container containing the gray board slurry, it can only contact the surface of the gray board slurry and cannot fully contact the gray board slurry, resulting in uneven heating of the gray board slurry and reducing the uniformity of the steam heating of the gray board slurry.
