Problems solved by technology

[0002] The existing steam sterilization tanks used in the production process of microbial fermentation generally adopt the static steam sterilization method, which has the defects of slow heating speed, long sterilization time and incomplete sterilization; the existing The cooling of the equipment and method after sterilization mainly adopts natural cooling, which makes the cooling time long and reduces the production efficiency. At the same time, the negative pressure is formed after the sterilization tank is cooled, which is easy to cause the bacteria in the sterilization tank to be polluted again

Embodiment Construction

[0013] As shown in the figure, the embodiment of the sterilization system of the present invention includes a steam sterilizer 1 that can be fed with high-temperature steam. The steam sterilizer has a conventional steam inlet and a steam exhaust port, and also has an air inlet 11 and An air outlet 12, an air pump 2 is connected to the air inlet 11 through an air filter 3-1, and the air outlet 12 leads to a sterile space 5 through a section of air transmission pipeline 4, which can be a sterile culture room , Aseptic inoculation room and other necessary aseptic environment in the fermentation production process. In addition, the system also includes a vacuum pump 6, which is connected to the air inlet 11 on the steam sterilization tank through a check valve 7-1, so that the air inlet can be used as a suction port during the vacuuming process.

[0014] In order to further prevent recontamination in the steam sterilization tank, an air filter 3-2 and a check valve 7-2 are also ar...

Abstract

The invention relates to a steam sterilization system used in the fields of microbial fermentation production, the food production and pharmacy, etc and a sterilization and cooling method thereof, wherein, the system comprises a steam sterilization tank in which high temperature steam can be pumped, and the steam sterilization tank is provided with a conventional steam inlet and a steam exhaust port, as well as an air inlet and an air outlet; an air pump is connected to the air inlet through an air filter; the air outlet communicates with a sterilized space through a segment of air transmission pipe. The steam sterilization system and the sterilization and cooling method thereof can speed up the sterilized cooling process in the mode of air convection and meanwhile reuse the sterilized air which participates in the cooling, with good sterilization effect.

Description

technical field [0001] The invention relates to a steam sterilization system and a sterilization and cooling method used in the fields of microbial fermentation production, food production, pharmacy and the like. Background technique [0002] The existing steam sterilization tanks used in the production process of microbial fermentation generally adopt the static steam sterilization method, which has the defects of slow heating speed, long sterilization time and incomplete sterilization; the existing The cooling of the equipment and method after sterilization mainly adopts natural cooling, which makes the cooling time long and reduces the production efficiency. At the same time, negative pressure is formed after the sterilization tank is cooled, which easily causes the bacteria in the sterilization tank to be polluted again. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steam sterilization system that can acc...
