The invention relates to the field of culture cultivation and discloses a field culture inoculating device and method. The device comprises a locking tank (1), a glass bottle (2) and a sterile air pipe (9), wherein a first sampling valve (3) is arranged at the edge of the bottom of the locking tank (1), the first sampling valve (3) communicates to a first angle valve (4), a second sampling valve (6) is arranged at the outlet of the glass bottle (2), the second sampling valve (6) communicates to a second angle valve (7), the outlet of the first sampling valve (3) communicates to the outlet of the second sampling valve (6) through a hose, and an opening is formed in the upper edge of the glass bottle (2) and communicates to the sterile air pipe (9). All parts are sterile without extra operations. Compared with a burning method in the prior art, the device is prevented from being in contact with air and operations of staff are reduced, so that the operating reliability and stability of the device are increased.
Description
technical field [0001] The invention relates to the field of strain cultivation, in particular to an on-site strain inoculation device and method. Background technique [0002] At present, in the fluid food and food industry, such as beer and condiments, the strains of the cassette cans are currently sterilized by steam, and the strains are cultivated in the aseptic laboratory, and finally the cassettes are transported. At the scene, press the bacteria cultured in the cassette tank into the seed tank through aseptic operation and prevent infection. However, the risk of strain infection and the death rate of strains are increased during the operation, which affects the fermentation quality and flavor of strains, and the labor intensity of personnel operation is high. The operation of the method is complex and has potential safety hazards. [0003] In the prior art, after CIP (cleaning in place, CLEAN IN PLACE) cleaning, use saturated steam to sterilize, replace the sampling...
