    The role of liquid nitrogen filling machine in filling liquid nitrogen in canned products

    Liquid nitrogen is transported from the liquid nitrogen storage tank to the gas-liquid separator through the ultra-high vacuum pipeline. The gas-liquid two-phase nitrogen is actively separated through the gas-liquid separator, and the gas and nitrogen are automatically discharged to reduce the sa...

    Attention to the use of liquid nitrogen tank

    Precautions during use of liquid nitrogen tank: 1. Due to the large heat of the liquid nitrogen tank, the thermal equilibrium time is longer when the liquid nitrogen is first filled, it can be filled with a small amount of liquid nitrogen to pre-cool (about 60L), and then slowly filled (so that i...
