用于研究微生物热致死动力学的可控加热速率的加热板系统

摘要

设计了一种用于研究微生物热致死动力学的可控加热速率的加热板系统,该系统包含铝制上加热板、下加热板、加热片、6个抽拉盒和6个样品单元、PID温度控制器、数据控制采集软件和计算机.实验结果表明,该可控加热速率的加热板系统工作时,上下加热板的温度与样品温度基本一致,设置的加热速率与样品的加热速率基本一致,这为研究微生物的热致死动力学提供了研究基础.%Acontrolled heating rate/heating block system is designed,which consists of aluminum top heating block,aluminum bottom heating block,custom-made heating pads,6 pull-push boxes,6 TDT cells,PID temperature controller,data collection software and computer.The results show that the temperature of top/bottom heating block and samples is almost the same when the controlled heating rate/heating block system works.This provides the research basis for studying the thermal death kinetics of microbiology.
