Microorganism sterilization and inoculation device

Abstract

The invention relates to the technical field of microorganism inoculation instruments, and particularly relates to a microorganism sterilization and inoculation device. The microorganism sterilization and inoculation device comprises a sterilization and inoculation box, wherein foot blocks are fixed at the bottom of the sterilization and inoculation box; the back side of the sterilization and inoculation box is connected with a power line; a control panel is arranged on one side of the sterilization and inoculation box; a box door is hinged to the front side of the sterilization and inoculation box; a handle is arranged on the box door; an inoculation dish lifting mechanism is fixedly mounted at the bottom of the inner side of the sterilization and inoculation box; an inoculation dish is placed at the upper part of the inoculation dish lifting mechanism; ultraviolet sterilization lamps are fixedly mounted on the sterilization and inoculation box on the two sides of the lifting mechanism; a partition plate is fixedly mounted in the middle of the sterilization and inoculation box; a blocking mechanism is arranged in the middle of the partition plate; a bacterial colony culture dish is arranged at the upper part of the partition plate. The device can keep a sterile state in an inoculation process, and can sterilize and disinfect an inoculation tool to prevent strain infection, so that the culture dish is prevented from being infected by bacteria, and further greater economic loss is avoided.

Description

technical field [0001] The invention relates to the technical field of microorganism inoculation instruments, in particular to a microorganism sterilization inoculation device. Background technique [0002] In chemical engineering, bioengineering, medical engineering and other fields, bacterial contamination by industrial fermentation will cause huge economic losses, and there are various factors causing bacterial contamination. Bacteria contamination in the inoculation process is a major factor. Therefore, in the industrial fermentation process, sterilization work is usually required during the inoculation process to prevent the fermentation colony from being infected by germs and cause large economic losses; the commonly used inoculation method is flame. Circle method, before inoculation, use alcohol cotton to wipe the inoculation port and the surrounding area of ​​the fermenter, first set the alcohol cotton ring around the inoculation port, ignite the alcohol cotton ring,...

Problems solved by technology

Bacteria contamination in the inoculation process is a major factor. Therefore, in the industrial fermentation process, sterilization work is usually required during the inoculation process to prevent the fermentation colony from being infected by germs and cause large economic losses; the commonly used inoculation method is flame. Circle method, before inoculation, use alcohol cotton to wipe the inoculation port and the surrounding area of ​​the fermenter, first set the alcohol cotton ring around the inoculation port, ignite the alcohol cotton ring, burn for about 15 seconds, slowly open the inoculation port with a wrench, and put it on the flame Fully burn for about 10 seconds, put the tank pressure to zero and quickly open the cap of the inoculation bottle, pour the seed solution into the fermenter under the protection of the flame, but there are many shortcomings in this inoculation and sterilization method: such as complicated operation, The inoculation time is long, and it is necessary to wait for the tank pressure to drop to normal pressure during the operation. During this period, the device is opened and the fermenter is exposed to the air, which is easy to cause bacterial contamination, which in turn causes the fermenting bacteria to infect other bacteria, causing huge economic losses. , so we propose a microbial sterilization inoculation device to solve the above problems
