Keeping Fresh Of Pre-made Food：Quick-freezing Below 30 Degrees——Conveyor Mesh Belt

In the pre-made food industry, quick-freezing for keeping fresh has been the core technology for ensuring the quality of pre-made food. The technology of quick freezing below 30 degrees can effectively kill microorganisms in the food and prevent their reproduction and deterioration, thus ensuring the hygiene and safety of pre-made food.

Metal conveyor mesh belt for quick freezing industry

At present, the commonly applied freezers are mainly divided into spiral tower freezer and tunnel freezer.

For spiral tower freezer, it is suitable for the application in space-saving workshops. The diameter of a tower is between 2 and 4 meters, and the mesh belt can be stacked about 20 stories high.

Widely used mesh belts are LF2 Belt and PF2 Belt.

For tunnel freezer, it is usually 20 meters long and 4 meters wide. The effective area for mesh belt achieves 80 square meters, which has a high freezing efficiency.

Food can be quickly cooled and frozen below 30 degrees within about 20 minutes.

The future of pre-made food

According to relevant surveys, the market size of China's pre-made food in 2022 is RMB419.6 billion. It is expected to reach RMB510 billion in 2023 and rise to RMB trillion-grade in 2026.

At present, the pre-made food industry is gradually maturing, but also gradually into the important period of high quality development. The demand for high quality conveyor mesh belts which are applied to the quick freezing for keep the fresh of pre-made food will continue to increase.
