    Liquid nitrogen tunnel freezer is an important meat and seafood freezing equipment in the food processing industry. In actual use, the economical liquid nitrogen tunnel freezer’s rapid freezing performance will freeze various types of food And the fresh-keeping effect has an obvious and direct important impact. Here is a brief introduction to the three main factors that affect the use of liquid nitrogen tunnel quick-freezers.

1. Quality factors of refrigerant

    The liquid nitrogen tunnel freezer uses liquid nitrogen as the refrigerant. The quality of the refrigerant will directly affect the freezing effect and freezing time of the food. The refrigerant in the liquid nitrogen tunnel freezer is directly separated from the nitrogen in the air. Manufactured, the composition of nitrogen needs to ensure high purity and sufficient quantity and can be monitored in real time. Once there is a shortage of nitrogen, the liquid nitrogen tunnel quick-freezer needs to be able to automatically supplement nitrogen.

2. Equipment system performance factors

    The factors that affect the cooling effect of liquid nitrogen tunnel freezer, as well as the performance setting of the equipment itself, the cooling effect produced by liquid nitrogen tunnel freezer in different application scenarios is also very different. It will be different when freezing fruits and vegetables and frozen meat products. There is a significant difference. The use of liquid nitrogen tunnel freezer for meat products to freeze fruits and vegetables does not keep the fruit and vegetable food with good freshness. Therefore, if you want to maintain the effect of the liquid nitrogen tunnel freezer, you need to ensure its performance. Applicability and symmetry.

Three, equipment maintenance factors

    At present, most of the liquid nitrogen tunnel freezer equipment used in the market are intelligent automation equipment, but before use, its parameters need to be accurately adjusted and tested, and the fresh food is put into the liquid nitrogen adjusted to the fine parameters. The freezing effect can only be ensured in the tunnel quick-freezer. In addition, the liquid nitrogen tunnel-type quick-freezer equipment also requires the operator to regularly perform operations such as equipment internal cleaning and equipment shutdown maintenance to ensure the excellent fresh-keeping effect of the liquid nitrogen tunnel-type quick-freezer equipment.

    The conscientious service of liquid nitrogen tunnel freezer currently has a good preservation effect in terms of frozen food, but there are still many factors that will directly affect the freezing effect of liquid nitrogen tunnel freezer, usually these factors include refrigerant Quality factors, equipment system performance setting factors and equipment maintenance factors
