Fermented milk sampling infectious microbe detection device for production

Abstract

The invention discloses a fermented milk sampling infectious microbe detection device for production. The device comprises a base and a mounting plate fixed on the base, the mounting plate is provided with a liquid strain mixing part and a gas strain culture part, the mounting plate is provided with a constant temperature box for culturing a strain culture mixed solution at a constant temperature, the mounting plate is provided with a detection part used for observing the number of infectious microbe colonies, the liquid strain mixing part is used for mixing fermented milk liquid and a culture solution, the mixed culture mixed solution is subjected to constant-temperature culture in a constant-temperature box, and the gas strain culture part is used for performing constant-temperature culture on a mixed solution of gas and the culture solution, and the detection part is used for observing the colony count of the liquid strain mixed solution and the gas strain mixed solution, observing whether bacterial contamination exists or not and judging the bacterial type. The device can perform pretreatment and detection on a sample, the whole process is continuous, sampling detection of infectious microbe by experimenters is greatly facilitated, and efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of detection of miscellaneous bacteria, and in particular relates to a device for detecting miscellaneous bacteria by sampling fermented milk for production. Background technique [0002] Fermented milk products have probiotic functions and are increasingly becoming people's new favorites. However, bacterial contamination often occurs in actual production, which seriously affects product quality and safety. In the modern industrial fermentation process, both solid-state fermentation and liquid-state fermentation will use sterile air to meet the needs of microbial growth, especially in oxygen consumption. In high-type fermentation production, the process air needs to be strictly aseptic. Once airborne bacteria occurs, it will have a great impact on fermentation production. Therefore, how to ensure the quality of sterile air is particularly important. Sterile air in the production process of fermented milk Th...

However, bacterial contamination often occurs in actual production, which seriously affects product quality and safety. In the modern industrial fermentation process, both solid-state fermentation and liquid-state fermentation will use sterile air to meet the needs of microbial growth, especially in oxygen consumption. In high-type fermentation production, the process air needs to be strictly aseptic. Once airborne bacteria occurs, it will have a great impact on fermentation production. Therefore, how to ensure the quality of sterile air is particularly important. Sterile air in the production process of fermented milk The sampling method adopted for the detection of mixed bacteria in fermented milk liquid is: through random selection of any number of hair latex production equipment, several parts of sterile air and several parts of fermented milk liquid during the fermentation process are collected for later use, and the liquid samples are sent to the laboratory. Add the culture solution into the culture medium in the room and cultivate it at a constant temperature. The air sample is passed into the culture bottle and the culture solution is added to the constant temperature culture. Bacteria type, found in actual operation, when the number of control test groups is large, the workload of the inspectors is large, the efficiency is low, time-consuming and laborious, and the liquid and gas need to be detected separately during the inspection process, which is inconvenient
