Description

Technical Field

[0001] This utility model relates to the technical field of controlled atmosphere storage, and in particular to a controlled atmosphere storage with an airflow distribution detection device. Background Technology

[0002] Controlled atmosphere storage is an advanced warehousing facility that, based on refrigeration, precisely controls the composition of gases (O2, CO2, N2 ratio), temperature, and humidity within the storage area to inhibit the respiration of fruits and vegetables and extend their shelf life. Its core challenge lies in ensuring the uniformity of gas distribution. Uneven airflow can lead to localized loss of gas concentration or temperature and humidity, causing fruits and vegetables to mold, lose moisture, or ripen prematurely.

[0003] For example, in a prior art represented by application number CN202122683710.7, the main structure includes a controlled atmosphere storage body. An air inlet pipe is located at the lower end of one side of the controlled atmosphere storage body. One end of the air inlet pipe is inserted into the interior of the controlled atmosphere storage body and connected to a connecting pipe. Both ends of the connecting pipe are movably connected to intermediate pipes, and a rotatable air outlet pipe is installed on the intermediate pipes. An air outlet is also provided at the upper end of the other side of the controlled atmosphere storage body. This fresh air system can be used to exchange air inside the controlled atmosphere storage body, so as to quickly expel harmful gases from the storage body and introduce fresh air, thereby extending the storage time of fruits and vegetables.

[0004] During use, it was found that existing controlled atmosphere storage facilities are not convenient for reducing internal carbon dioxide and ethylene, causing fruits and vegetables to ripen too quickly. Therefore, there is an urgent need for a controlled atmosphere storage facility with an airflow distribution detection device. Utility Model Content
