Frozen food is one of the rapidly developing food industries in the world today. Fresh processed food is quickly frozen at low temperatures after appropriate pre-treatment and shaping, and then stored, transported, and sold at temperatures of minus 18 degrees Celsius or lower. China is a major producer of frozen food, including resource products such as fruits and vegetables, meat, poultry, eggs, aquatic products, and grain products.

The spiral quick freezing machine has a small footprint and can provide the uniform closed circulation airflow required for quick freezing of advantageous products.

With the advancement and development of refrigeration technology, people's attention to food will become increasingly high. In addition, consumer upgrades and the pace of people's lives will make low-priced, convenient and fast food widely popular, and niche markets will become more segmented. To cope with these, enterprises must strictly control raw materials, choose small and refined products, develop new products and processes, and pay attention to the consumption habits and tastes of young people. In other words, making "specialized products" is more profitable.

And this is also a challenge for refrigeration methods, equipment, and technology. Whether the technical requirements of such products can be guaranteed becomes the key to determining the future development of refrigeration equipment enterprises. Technology comes first, products come later. The places where technology can reach are the places where innovative products can be developed. Without technical support, products will be unsustainable.
