Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration equipment and relates to a fluidized bed air duct for generating suspended airflow. Background Art

[0002] In the quick-frozen food industry, fluidized bed quick freezers have gradually become the preferred equipment for many food production companies due to their unique quick-freezing method and high efficiency. Fluidized bed quick freezers use high-pressure fans to inject cold air into the freezing chamber, causing the food on the porous conveyor to fluidize, thereby increasing the contact area between the food and the cold air, accelerating the freezing speed, and making the food flow during the freezing process, thereby accelerating the speed of heat transfer and exchange and improving freezing efficiency.

[0003] Currently, fluidized bed air ducts cannot ensure uniform distribution and effective flow of the freezing airflow. If the cold air flow is unevenly distributed, it may cause the air volume in some areas to be too large or too small, which in turn causes uneven freezing or splashing of food during the freezing process.

[0005] The technical solution of the utility model is as follows:
