Abstract
Description
Technical Field
[0001] This utility model relates to the field of precooling equipment technology, and in particular to an atomizing cooling device. Background Technology
[0002] With the vigorous development of transportation networks across the country, people have gradually been able to eat all kinds of food from all over the country; however, in order to keep food fresh for a longer period of time, people usually use equipment such as cold storage and refrigerated trucks to process, store and transport food, thus promoting the development of food refrigeration and preservation technology.
[0003] In existing food refrigeration and preservation technologies, air cooling is commonly used for food preservation. For example, patent document CN202675502U discloses a novel air-cooled evaporator, which mentions that in a cold storage, cold air generated by the evaporator is blown by fans to form cold air. However, due to the limitations of the installation position of the fans and evaporators in the cold storage, the cold air blown out is unevenly distributed in space. Areas near the air vent cool down quickly and have low temperatures, while areas far from the air vent cool down slowly and have high temperatures, which affects the quality and freshness of the food. On the other hand, the fans are designed to accelerate the flow of cold air in the cold storage and make the cold air distribution more even. However, food will gradually lose moisture under the air flow. This means that accelerating the air flow will make the food more prone to dehydration and drying, causing food, especially fruits and vegetables, to lose its fresh taste and nutrients, resulting in poor preservation effect.
[0004] To address this issue, differential pressure precooling is often employed. However, in existing technologies, differential pressure precooling devices typically spray directly onto the food during the atomization and humidification process. This can lead to uneven moisture levels, with some food items experiencing excessively high humidity while others remain too dry, making the food more susceptible to spoilage and resulting in significant cost waste.
