The liquid nitrogen filling machine can accurately control the amount of liquid nitrogen, with the ability to add nitrogen without containers. PLC controlled programming, compact appearance, and easy installation can be used with any production line. All pipelines are equipped with vacuum liquid nitrogen insulation pipes, which can ensure lower liquid nitrogen consumption and a frost-free operating environment to a greater extent.
one、 Working conditions of liquid nitrogen refueling machine:
1. Liquid nitrogen supply: Adjust to 15 (0.1MPa) and connect to the liquid nitrogen port.
2. Compressed air or nitrogen: used to supply the filling valve. need ¼″ Pipes with a diameter and pressure range of 50-100 psig (3.4-6.9 bar). The set pressure of 50 psig (0.35MPa) is too high and has a significant impact, which is not conducive to the lifespan of the filling valve core and internal vacuum pipeline.
two、 Liquid nitrogen metering and filling system:
1. The filling method without tanks or filling intervals reduces the consumption of reduced pressure liquid nitrogen and reduces operating costs.
2. Vacuum insulation - With a particularly low daily evaporation rate of about 0.15 liters per hour, the operating cost of the liquid nitrogen machine is reduced.
3. The nozzle nitrogen care system prevents external air from entering the spray chamber and frosting inside.
4. Liquid nitrogen horizontal positioning control, stable horizontal pressure, improving the accuracy of liquid nitrogen dosage,
5. Simultaneously reduce the loss of liquid nitrogen caused by flash evaporation.
6. The liquid level is controlled by the positioning of the power system, avoiding maintenance issues related to electronic liquid level control system and electric valve malfunctions.
7. Liquid gas phase separator ensures that the liquid nitrogen is in a very cold state, improving the quality of the "pure liquid phase" and helping to achieve accurate liquid nitrogen dosage.
8. Buffer nitrogen filling function, effectively preventing liquid nitrogen from rebounding and splashing out, ensuring stable liquid nitrogen pickup and stable tank pressure.
9. Equipped with a filter (option) of 10um to remove particulate pollution.
three、 The liquid nitrogen filling machine is suitable for the filling and production of various pure water, mineral water, fruit juice drinks, tea drinks, and edible oils. After simple adjustment of some components, this machine can also be used for the filling and production of pure water and mineral water. The Micro-g environment negative pressure filling technology is adopted to make the filling more rapid, stable and accurate. The equipment is equipped with a perfect reflux system to avoid the secondary pollution and oxidation of beverages; This equipment can meet the requirements of hot filling technology below 95 ℃. It adopts advanced technologies such as human-machine interface touch screen control, PLC computer control, and frequency converter control.
