Detection system for flora detection in food substance

Abstract

A detection system for flora detection in a food substance comprises a detection box body, an infrared light heat supply assembly, a signal acquisition assembly, a luminous lamp group and a displayer; the detection box body comprises a bottom box and a box cover, and the bottom box is provided with a gas inlet; the infrared light heat supply assembly comprises an infrared irradiation lamp; the signal acquisition assembly comprises detectors, an optical shadow detection board and a circuit board, and the optical shadow detection board comprises detection blocks each designed with a square structure; the luminous lamp group comprises LED lamp beads; the displayer is internally provided with a display card, and the display card is connected with a processor. The infrared light heat supply assembly maintains the temperature in the detection box constant, oxygen supply in the detection box is ensured through arranging the gas inlet, and the pollution problem of flora culture can be timely found out through the detectors. The system can reduce the labor intensity for flora culture to a largest extent, and with the arrangement of the optical shadow detection board, the flora size is convenient to measure.

Description

technical field [0001] The present invention relates to the technical field of food safety identification equipment, and more specifically relates to a detection system for detecting bacterial flora in food substances. Background technique [0002] In the prior art, the detection of flora in food substances generally adopts the following method: use a petri dish to accommodate the culture medium, collect random samples of the target samples, place the collected samples in the culture medium, and then pass The constant temperature culture for a period of time judges the flora according to the colony and the diffusion area of ​​the colony. [0003] In addition, in the test of bacterial resistance to antibiotics, the size of the spread area of ​​the colony culture will also be measured. The specific operation is: take two vertical coordinates and take the maximum value. However, in the process of colony culture, its diffusion does not expand outward according to the uniform di...

AI Technical Summary

Problems solved by technology

However, in the process of colony culture, its diffusion does not expand outward according to the uniform diffusion method, and sometimes the colony spreads abnormally due to the unevenness of the medium. Therefore, the above-mentioned size measurement method will result in reliable monitoring data. decrease in sex

[0004] And, it should be noted that: in the prior art, the colony culture adopts simple petri dishes for cultivation, the equipment is simple, it is difficult to maintain a constant temperature, and the measurement of the size is performed manually by the operator, and the workload of the measurement is larger
