AI Technical Summary

Technical Problem

Quantitative strains are prone to moisture absorption and shrinkage during the repackaging process after freeze-drying, which affects the repackaging effect and the stability of the bacterial count, and the repackaging process is time-consuming.

Method used

The system employs a combination of a dripping mechanism and a moving mechanism, using a micro-peristaltic pump to drip bacterial solution into individual containers, forming quantitative bacterial microspheres. These microspheres are then rapidly freeze-dried in a liquid nitrogen environment, eliminating the need for repackaging.

Benefits of technology

This technology enables rapid freeze-drying of bacterial solutions into pellets, avoiding moisture absorption and adhesion, ensuring bacterial count stability, saving manpower, and improving operational efficiency.

Abstract

The utility model provides a quantitative strain ball dropping device, which relates to the technical field of microbial culture and comprises a liquid dropping mechanism, a liquid dropping tray, a moving mechanism and a base plate, the liquid dropping mechanism is mounted on the base plate, the moving mechanism is mounted on the base plate and positioned below the liquid dropping mechanism, the liquid dropping tray is mounted on the moving mechanism, and the moving mechanism is positioned below the liquid dropping tray. The liquid dropping disc is used for containing a plurality of independent containers, the movement direction of the liquid dropping mechanism is perpendicular to the movement direction of the moving mechanism, and the liquid dropping mechanism and the moving mechanism move in a crossed mode to ensure that quantitative strains are dropped into all the independent containers in the liquid dropping disc. According to the utility model, the small balls are prevented from absorbing moisture, shrinking or adhering together in the sub-packaging process, and the beneficial effects of short sub-packaging time and convenience in sub-packaging are achieved.
