Abstract
This invention discloses an enrichment assembly for use before testing for pathogenic bacteria in food, comprising three independent bags for containing bacterial solutions and a worktable. The three bags are detachably mounted on the worktable. The worktable is provided with sequentially arranged mounting positions for pre-enrichment bags, transfer bags, and selectable enrichment bags, and is equipped with a first peristaltic pump, a first solenoid valve, a second peristaltic pump, a second solenoid valve, and a control device. After each bag is placed in its respective mounting position on the worktable, the pre-enrichment bag is connected to the first peristaltic pump, the first solenoid valve, and the transfer bag via piping. The transfer bag is connected to the second peristaltic pump, the second solenoid valve, and the selectable enrichment bag via piping. This invention automates the enrichment step before food microbiological testing, eliminating the risk of cross-contamination, saving manpower, and improving efficiency.
