采用干热灭菌技术时的关键问题

　　CANADA - A Graduate Student with the University of Saskatchewan says the biggest challenge, when using heat to kill diseases causing pathogens in swine transport trailers, is ensuring all surfaces reach a high enough temperature to kill the organisms, Bruce Cochrane writes.As part of research being conducted on behalf of Swine Innovation Porc aimed at developing an automated system for cleaning and disinfecting swine transport trailers, scientists are assessing the value of Thermal Assisted Drying and Decontamination.The goal of TADD is to use heat to raise the interior surfaces of livestock transport trailers to high enough temperatures for specified amounts of time sufficient to deactivate dangerous pathogens.

　　布鲁斯·科克伦(Bruce Cochrane)写道，据加拿大萨斯喀彻温大学的一名研究生称，当用高温杀灭生猪运输拖车内疾病病菌时，有一个最大的挑战，即要确保拖车内所有表面都能达到一定高的温度，方能消灭这些微生物。作为以加拿大养猪创新项目组织为代表进行的部分研究，就是要研发一套用于清洗和消毒生猪运输拖车的自动化系统，科学家们正在对干热灭菌技术(TADD)的价值进行评估。干热灭菌技术的目的是利用高温，让牲畜运输拖车内部设备表层在指定时间内达到足够高的温度，最终使危险的病原体失去活性。
