A hot-air sterilizer capable of exposing airborne microorganisms to elevated temperatures with an almost instantaneous heating time was developed and evaluated. With this apparatus, aerosolized Bacillus subtilis var. niger spores were killed in about 0.02 sec when exposed to temperatures above 260 C. This is about 500 times faster than killing times reported by others. Extrapolation and comparison of data on the time and temperature required to klll B. subtilis var. niger spores on surfaces show that approximately the same killing time is required as is necessary for spores in air, if corrections are made for the heating time of the surface.
开发并评估了一种热空气消毒器，它能够使空气中的微生物暴露于高温下，且加热时间几乎是瞬间的。使用该设备，雾化的枯草芽孢杆菌黑色变种孢子在暴露于260℃以上的温度时，约0.02秒内即可被杀死。这比其他人报告的杀灭时间快约500倍。对在表面杀灭枯草芽孢杆菌黑色变种孢子所需的时间和温度数据进行外推和比较表明，如果对表面的加热时间进行校正，那么表面孢子所需的杀灭时间与空气中孢子所需的杀灭时间大致相同。
