PROBLEM TO BE SOLVED: To provide a sterilization method for granules capable of continuously efficiently sterilizing a granular material. SOLUTION: This sterilization method for granules comprises such processes that raw material powder is supplied between each closely rotating perimeter sides of 2 rollers 5, granules are compressed with the rotation of the each perimeter side, the raw material powder receives at the closest contact point of the each perimeter side the largest linear pressure which eradicates bacterium followed by being discharged, and since a superhigh pressure treatment apparatus 1 having the 2 rollers 5 is an open system, the raw material powder can be continuously put in, thus sterilization of a granular material can be continuously efficiently done. |
