Embodiment Construction

[0075]According to the detection principle and technology proposed by the present invention, specific detection equipment can be designed.

[0076] Detector embodiment one of the present invention sees figure 1 , there are support feet 22 below the chassis 1. An ultraviolet lamp 4 is housed in the upper cover 2 of the chassis, and its function is to sterilize and disinfect the parallel accommodation cavity 5 before formal testing. There are two identical parallel accommodation cavities 5 below the ultraviolet lamp 4, a sealing cover 3 is arranged on the parallel accommodating cavity, and a sealing rubber ring 15 is arranged on the edge of the sealing cover, and its function is to strengthen the sealing. There is an air outlet at the bottom of each parallel accommodation cavity, and the air outlet communicates with the water vapor filter 10 through the upper guide pipe 8 respectively, and the water vapor filter is connected with the carbon dioxide detection device 11 through t...

Abstract

The fast detection method and instrument for microbe content in food has two parallel sample detecting systems adopted, including one for food sample detection and the other for detecting contrast. These two systems are in the same environment conditions and heated with the same heating element, the CO2 these two systems generate is detected separately in two identical CO2 detecting devices, and the detected data are analyzed and processed to obtain the detection result. The present invention has short detection period, simple structure, low cost and other advantages, and is suitable for fast site detection.

Description

(1) Technical field [0001] The invention relates to a method and equipment for rapid detection of microbial content in food. (2) Background technology [0002] The method and equipment proposed by the invention are mainly used for rapid detection of the content of harmful microorganisms in food. Diseases caused by eating food contaminated by microorganisms are called foodborne diseases. With the changing environment and the abuse of antibiotics, although people's living and sanitary conditions have been continuously improved, their resistance to germs has been declining, and foodborne diseases have been on the rise. Therefore, the detection and inspection of pathogenic bacteria in food is more and more important. However, most conventional detections rely on the method of cultivating target microorganisms to determine whether the food has been contaminated. The cultivation time ranges from 2-3 days to several weeks, and because the number of colonies is counted visually, i...
