Description

Technical Field

[0001] The utility model relates to the technical field of microbial agent production, in particular to a sterilization device. Background Art

[0002] Microbial agent refers to a live bacterial preparation made by using porous substances as adsorbents (such as peat and vermiculite) to adsorb the fermentation liquid of the target microorganisms (effective bacteria) after industrial production and expansion. This type of agent is used for seed dressing or root dipping, and has the functions of directly or indirectly improving soil, restoring soil fertility, preventing soil-borne diseases, maintaining the balance of rhizosphere microbial flora, and degrading toxic substances. During the production process of microbial agents, harmful microorganisms contained in the agents need to be sterilized.

[0003] A Chinese patent discloses a sterilization device for the production of microbial inoculants (authorization announcement number CN209286249U), which can use a cooling pipe to pass cold water into the cylinder after sterilization is completed to reduce the temperature inside the cylinder and reduce the density of steam to prevent steam splashing during the deflation process. After the upper cover is opened, the inner liner can be driven up by a spring to facilitate the staff to quickly and safely take out the culture dish. It is safe and reliable. However, according to the description in its manual and common knowledge, since the high-temperature steam will adhere to the inner liner in the form of water droplets during sterilization, and since the inner liner is not rinsed before sterilization, the high-temperature steam is easy to adhere to the inner liner and combine with the microorganisms on its inner wall, and finally drip on the culture dish, thereby contaminating it.

When the flushing is completed, the box door 2 is opened, and the culture dish is placed in the inner tank 7, and then the box door 2 is closed. At this time, the heating tube 9 is turned on again, and the high-temperature steam generated by the heating tube 9 can sterilize the microbial inoculant in the culture dish. Finally, the box door 2 is opened to take the inner tank 7 and the culture dish.
