When liquid nitrogen level reaches the 4/5 of heat exchange storehouse 23, the liquid nitrogen liquid feed valve of refrigerant feed liquor vacuum tube 1 is closed, and stops feed liquor.Work as liquid level
Less than heat exchange storehouse 23 4/5 when, the liquid feed valve of refrigerant feed liquor vacuum tube 1 is again turned on feed liquor.With this cycle operation.Equally,
When sterile liquid nitrogen level reaches the 2/3 of heat exchanger tube 27, the valve of sterile nitrogen air inlet pipe 5 is closed, and is stopped into sterile nitrogen.When
When liquid level is less than the 2/3 of heat exchanger tube 27, the valve of sterile nitrogen air inlet pipe 5 is again turned on into sterile nitrogen.With this circulation industrial
Make.)
Sterile liquid nitrogen feed liquor and filling process：
After sterile liquid nitrogen occurs, when the 3rd liquid level temperature integrative sensor 11 detects wherein sterile liquid nitrogen level deficiency
When, 7 control valve of liquid inlet control valve is opened, and sterile liquid nitrogen is entered in sterile liquid nitrogen filling tank 26 by sterile nitrogen storage tank 5.Filling
When, the refrigerant of 0.6b is passed through in filling head protection pipe 17, filling cylinder 14 pulls open filler headkerchief 28, exposes filling head and carry out
Fill, the effect that nitrogen is passed through in filling head protection pipe 17 is the air driven away in filling head, makes the filter screen 15 in filling head
It is not-easy-to-freeze with nozzle 16, influence to fill effect.
Nitrogen is first passed through during use to be vented and purged, and remaining air in each tank body is removed, secondly being passed through height
Warm nitrogen carries out disinfection sterilization, produces sterile nitrogen again afterwards and is filled, during can be whole by the bacterium in system
Remove, the nitrogen for ensureing out is entirely sterile, safety and sanitation, preferably meets the use demand of people, in addition operation letter
Single, production efficiency is high when noting nitrogen.
