AI Technical Summary

Technical Problem

During solid fermentation without spore-producing Aspergillus niger, traditional inoculation and stirring methods have many challenges, including the pipette tip pore size is too small to absorb mycelium, and the traditional stirring methods increase the risk of contamination and waste inoculation time.

Method used

A solid fermentation and inoculation stirrer without sporophyllum is designed, including a cylindrical shell, a liquid absorbing ball, a liquid reservoir and a stirring rod. The liquid suction port of the stirring rod is designed with a moderate pore size. It can directly absorb the mycelium and quickly stir the mycelium and the culture medium after inoculation.

Benefits of technology

The stirrer significantly improves the inoculation efficiency and stirring uniformity, reduces the risk of contamination, and is especially adapted to the characteristics of the mycelium of non-spore-producing Aspergillus niger. The simple and fast operation greatly reduces the inoculation time and stirring time.

Abstract

The utility model relates to the technical field of fermentation inoculation tools, in particular to a non-sporogenic aspergillus solid-state fermentation inoculation stirrer which comprises a shell, the shell is of a cylindrical structure, a liquid absorption ball is installed at one end of the shell, a liquid storage cavity is installed at the other end of the shell, a stirring rod is arranged in the shell, and a liquid absorption opening is formed in the outer side of the liquid storage cavity. A limiting plate is mounted on the outer wall of the stirring rod, a limiting plate is mounted at the position, close to the liquid suction ball, of the inner wall of the shell, a groove is formed in the outer end of the limiting plate, a clamping spring is arranged in the groove, a movable clamping block is mounted at the outer end of the clamping spring, a limiting opening is formed in the position, close to the liquid storage cavity, of the inner wall of the shell, and the outer end of the stirring rod slides after being stressed; and one end extends out of the liquid suction port to drive the movable clamping block to be clamped into the limiting port. According to the solid-state fermentation inoculation stirrer for the aspergillus sporogenes, the technical problems in the traditional inoculation and stirring process are effectively solved, the inoculation efficiency and the stirring uniformity are remarkably improved, and the pollution risk is reduced.
