AI Technical Summary
Traditional bacterial detection methods struggle to ensure the uniformity of dried bacterial samples, leading to inaccurate results. In particular, the varying shapes, sizes, and textures of dried bacteria can result in uneven bacterial distribution.
A device for detecting bacterial count in dried bacteria was designed. The dried bacteria are ground into powder through a grinding shell to make the sample more uniform. The dried bacteria sample is refined by a rotating motor, a chopping blade and a grinding roller, and quantitative delivery is achieved through a filter screen and a quantitative auger to ensure that the sample is in full contact with the detection system.
This method achieves uniform refinement of dried bacterial samples, improves the representativeness and accuracy of test results, shortens the test time, and avoids test errors caused by local differences in bacterial content in block samples.
