Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration, in particular to a spiral top-blowing air duct. Background Art

[0002] Product freezing refers to a low-temperature preservation method that uses low temperatures to inhibit the growth of microorganisms in aquatic products and slow down chemical reactions such as lipid oxidation and non-enzymatic browning, allowing them to maintain excellent quality during storage. Freezing methods for aquatic products can be divided into spiral and tunnel types. The spiral type installs a liquid nitrogen injector in the center of the equipment, placing the aquatic product in the spiral disk, which can achieve more comprehensive quick freezing of the aquatic product. The air duct design of existing refrigeration equipment is still insufficient, so there is room for improvement in this area. Utility Model Content
