The background of liquid nitrogen quick freezing technology

1. At the end of the 1950s, due to the development of space technology, the demand for a large amount of liquid oxygen produced as rocket fuel promoted the rapid development of the air liquefaction and separation industry. The production of liquid nitrogen makes it possible to produce a large amount of 78% of nitrogen in the air by liquefaction, thus opening up a way for new applications in the frozen food industry.

2. In the early 1960s, the frozen food industry in the United States faced a new turning point. At that time, frozen food developed in three directions:

(1) Frozen food is developing in the direction of "Individual Quick Freezing" (IQF);

(2) It is required to increase the production of frozen food through continuous quick-freezing device;

(3) Require frozen food to develop into high-quality quick-frozen fresh-keeping food. Because of these requirements, the freezing method must be updated technically, so the liquid nitrogen quick freezing technology came into being and was quickly widely used.

Nuoruida (Tianjin) science and Technology Co., Ltd. is committed to research, development, and sales of liquid nitrogen freezer. Using European technology, we provide a variety of equipment. The main equipment is liquid nitrogen cryogenic freezer, liquid nitrogen cabinet freezer, liquid nitrogen tunnel freezer,sub-zero processing equipment, cryogenic freezing equipment, and so on.
