PURPOSE:To accomplish the title sterilization in high efficiency without causing scorch by blowing hot air against cut or ground spice impregnated with moisture while being allowed to rotate in a vessel to heat the atmosphere within the vessel to a specified temperature. CONSTITUTION:A spice ground or cut into pieces of relevant size (e.g., garlic, onion) is impregnated with moisture and put into a rotatably set heating vessel. Thence, hot air is blown into the vessel under rotation with or without heating to heat the atmosphere within the vessel to 60-350 deg.C, thus accomplishing the objective sterilization under drying. Thereby the iron plate temperature on the inner wall of the vessel can be suppressed to ca.50-150 deg.C and can be prevented from scorching and/or fusing even for special spice of high saccharinity. To impregnate the spice with moisture, it is preferable that said spice be alternately and repeatedly put to hot water spraying and leaving to stand for a specified time. |
