The chili powder sample and diluent are added to the dilution cylinder 3 through the sample cylinder 5 and the diluent cylinder 6, respectively. The sample and diluent are thoroughly mixed by the stirring mechanism 4 to obtain the sample diluent. The sample diluent is then fed into the culture tank 10 through the delivery pipe 11 and the pump. The heating cylinder 15 and the heater 16 at its bottom can heat the nutrient agar. After cooling to a suitable temperature, it is fed into the culture tank 10 through the delivery pipe 17. The culture tray 9 can move back and forth by the action of the second electric cylinder 801 to shake the sample diluent and nutrient agar evenly. During testing, the first electric cylinder 701 raises the culture tray 9 to a suitable height. The second electric cylinder 801 then extends, moving the culture tray 9 forward so that the culture tank 10 can collect the sample diluent and nutrient agar. After collection, the second electric cylinder 801 reciprocates, moving the nutrient tray 9 back and forth to evenly distribute the sample diluent and nutrient agar within the culture tank 10. Finally, the second electric cylinder 801 retracts, moving the culture tray 9 backward so that the culture tank 10 is positioned below the microscope camera 14 for microbial observation and analysis. After testing, the first electric cylinder 701 lowers the culture tray 9 to facilitate cleaning of the device's components. During cleaning, a water basin can be placed at the front end of the L-shaped support plate to collect the cleaning solution from the heating cylinder or dilution cylinder.
