Analysis of Microbial State Eligible Reference Point in Export Down

It is aiming to choose optimum disposing model for the microorganisms in down.According to the criterions of China and Europe about microorganism in down,different disposing models of drying-time and steam-pressure which combines the practices in the down enterprises was designed.The different disposing model to the down was exerted and the microbial state was tested.The eligible reference point and optimum disposing model for the down was found.The experimental results indicated that the microbial state of down was eligible when drying-time was 25 min and steam-pressure was 0.35 Mpa.And it conclued that the sanitation state of down would be better after being disposed at exceeding eligible reference point.
