Abstract

The invention discloses a method and a device for rapidly detecting raw milk bacteria. The method comprises the following steps of step1, placing the milk to be detected in a centrifuge tube with a precipitator, and vibrating the centrifuge tube for 3-8 seconds; step 2, placing the centrifuge tube into a centrifugal machine for centrifugal treatment; step 3, absorbing a clear solution of a liquid middle layer in the centrifuge tube by using an injector, and injecting the clear solution into a sample pool of a detection device; step 4, starting a high-speed channel pump, and enabling a sample liquid in the sample pool to enter a high-speed channel; step 5, stopping the high-speed channel pump, starting a sampling pump, and enabling the sample liquid to enter a sample flowing groove; step 6, carrying out image collection on the sample liquid by using a microscopy camera, transferring a collected image to an accelerator; and the step 7, recognizing the image through the accelerator and the calculating the bacterial content in the sample liquid. According to the technical scheme, a condition that the raw milk bacteria are rapidly and accurately detected is realized, the detection precision is high, and the scheme is suitable for milk production processing enterprises and detection departments.

Description

technical field [0001] The invention relates to the field of microbial detection, in particular to a low-cost raw milk bacteria rapid detection method and device. Background technique [0002] Microorganisms that are harmful to humans are often called bacteria. Bacteria can be found anywhere in the world. Bacteria come into contact with humans mainly in three physical forms: gas, liquid and solid. The present invention can be used for the detection of bacteria in these three physical forms. But the real detection process is for liquids. [0003] For solid substances, the solid can be crushed first, then dissolved in the liquid, and then the liquid can be detected. [0004] For gaseous substances, the substances in the air can be mixed into the liquid through the gas scrubber, and then the liquid can be tested. [0005] Among liquids, the most relevant to human beings are edible beverages. The detection of milk in beverages is the most complex. The present invention de...
