Description

Technical Field

[0001] This utility model relates to the field of microbial inoculation equipment technology, specifically to an inoculation device that prevents contact contamination. Background Technology

[0002] In biotechnology fields such as microbial fermentation and cell culture, inoculation is a crucial step in transferring cultured microorganisms or cells to new culture media. Ensuring a sterile inoculation environment is paramount during this process. Contamination of the seed tank or fermenter by other microorganisms can range from affecting product yield and quality and increasing production costs to potentially causing complete fermentation or culture failure and resulting in significant economic losses.

[0003] Traditional inoculation devices and methods have many drawbacks. For example, some devices rely solely on simple flame sterilization, which is susceptible to contamination due to factors such as air stability, human error, and the inherent dangers of flame sterilization. Other devices use steam sterilization, but the residual moisture in the steam creates a humid environment that promotes bacterial growth, further increasing the risk of contamination. In addition, some inoculation devices have flawed structural designs that allow the inoculated material to come into contact with the outside air during operation, making it impossible to effectively prevent contamination by other microorganisms.

[0022] The present invention will now be described in detail with reference to the accompanying drawings: An inoculation device for preventing contact contamination includes an inoculation bottle 1, with a butterfly valve 101 connected to the outlet end of the inoculation bottle 1. The other end of the butterfly valve 101 is connected to a housing 2, which is a rotating structure made of stainless steel. The housing 2 has an inlet end that cooperates with the butterfly valve 101. An ultraviolet lamp sterilization section 3 and an electric heating section 4 are disposed inside the housing 2.

[0023] The ultraviolet lamp sterilization section 3 is used to sterilize the butterfly plate outlet side of the butterfly valve 101 and the inside of the glass tube 303. It utilizes the bactericidal effect of ultraviolet light to destroy the DNA structure of microorganisms, thereby achieving disinfection. The electric heating section 4 is used to sterilize the outlet tube, killing any bacteria that may be present on the surface of the outlet tube through heating, ensuring that the inoculation pipeline is in a sterile state.

[0024] The butterfly valve 101 includes a valve body, a butterfly plate, and a driving device.

The number of ultraviolet lamps 302 is greater than one, and they are arranged in a specific configuration within the cavity between the glass tube 303 and the outer shell 2. The ultraviolet lamps 302 are powered by an external power supply.

[0028] The heating wire 401 is spiral-shaped and wraps around the cavity between the liquid outlet tube and the outer shell 2. The heating wire 401 is powered by an external power source, and the heating temperature and time can be precisely controlled to meet different sterilization requirements.

[0029] The ultraviolet lamp 302 and heating wire 401 are powered by an external power source, which avoids the occurrence of insufficient power supply from the storage battery during the sterilization process.

[0030] The inoculation bottle 1 is made of high-pressure resistant and corrosion-resistant stainless steel to ensure the stability and safety of the inoculation bottle 1 during sterilization and inoculation.

[0031] Operating procedures: 1.
