TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Method: The lifting isolation flapper is front lifting isolation flapper and back lifting isolation flapper in which right and left sides of flappers are matched with side wall of ferment groove. The sealing of the isolation top is achieved by steam baffle or air baffle which passes frame plate and isolation area ferment wall and seal matching with the front and back lifting isolation flapper which inserted to ferment groove. The method involves after inoculating, the front lifting isolation flapper and back lifting isolation flapper rises, and moving to the next ferment groove position with the relative device which used to realize steam sterilizing, cooling, deodorizing inoculating, front and back lifting isolation flapper slows down to realize another step of steam sterilizing, cooling, deodorizing and inoculating process. The steam sterilizing is hot steam electrical generator or external steam source. The cooling step involves ventilating sterile-free air. The inoculating step involves spraying strain liquid to solid ferment material which is steam sterilized and cooled in isolation area. Preferred Device: The travel mechanism is speed regulating motor which drives the travel wheel by rotating mechanism. The lifting isolation baffle is provided at front and back. The lifting isolation flapper or steam baffle or air baffle is formed seal isolation area with the ferment groove. The air filtration mechanism is used for providing cooling air. The lifting isolation plugboard is provided for sealing and isolating the solid fermentation material in the fermentation tank and an isolated region top seal mechanism are also arranged on the frame plate. The upper part of strain liquid storage and transmission mechanism cylindrical reservoir is provided with strain liquid through hole. The lower part of the cylindrical reservoir is provided with a strain liquid outlet through hole which is connected with the spray pump. The lifting isolation flapper is provided with flapper lifting mechanism. The flapper mechanism comprises two driving gear-containing speed regulating motors, gear drives lifting isolation flapper which is provided with a gear strip, and lifting isolation flapper which is provided with a lifting slide match frame and ventilating or air pipe. The air filter mechanism is cylinder ultra-fine fiber glass which is installed in a micro-pressure container. The micro-pressure top is provided with air inlet and purifying control valve. The deodorizer is photolysis deodorizer. The steam source of the steam sterilizer is hot steam electrical generator or external steam source. The device further comprises steam outlet and steam control valve.
