AI Technical Summary

Technical Problem

Existing rotary inoculation equipment generates a large amount of foam on the surface of the culture medium due to the large impact kinetic energy during bacterial inoculation, which affects the full contact between the mycelium and the culture medium and the uniformity of inoculation.

Method used

The design consists of a water curtain outlet, an overflow chamber, an overflow weir, and an inclined surface. Combined with a drive assembly to rotate the plate, a thin film-like water curtain is formed. Large air bubbles are separated by baffles and grid assemblies. With the help of a pre-wetting assembly and a degassing and defoaming assembly, the uniform inoculation and defoaming of the bacterial solution are ensured.

Benefits of technology

This method achieves uniform inoculation of bacterial solution on the surface of the culture medium, reduces foam generation, improves inoculation efficiency and stability, and ensures full contact between mycelium and culture medium.

Abstract

This invention discloses a rotary inoculation device for Cordyceps cultivation, belonging to the field of bacterial inoculation. It includes a machine platform and a bacterial inoculation assembly fixed to the upper part of the machine platform. The bacterial inoculation assembly includes a first support fixed to the upper part of the machine platform, a first lifting part fixed to the first support, a first frame plate fixed to the lifting end of the first lifting part, and a water curtain outlet section disposed on the first frame plate. This design features a water curtain outlet section composed of an overflow chamber, an overflow weir, and an inclined surface. This allows the bacterial solution to accumulate in the overflow chamber and smoothly cross the overflow weir, flowing down the inclined surface to form a thin film-like water curtain. This water curtain shape reduces the falling kinetic energy of the liquid, dispersing the impact force from a point to a line, avoiding the problem of excessive foaming caused by traditional point-dropping. Combined with a drive component that rotates the plate, the water curtain sweeps across a complete fan-shaped area within the cultivation bottle, improving the inoculation uniformity and coverage efficiency of the bacterial solution on the culture medium surface.
