ARK Equipment & Engineering Co., Ltd.

The modified atmosphere refrigeration device is mainly used for long-term preservation of fruits and vegetables, with a preservation time of up to 60 days, meeting the consumption needs of crew members on long-term ocean voyages.

Integrating various preservation measures such as oxygen reduction, carbon dioxide reduction, temperature control, humidity control, ethylene removal, odor removal, sterilization and disinfection, and airtight storage (with humidifiers installed separately in the storage), and classifying storage according to the physiological characteristics of different types of fruits and vegetables. Through a preservation expert system, the optimal preservation parameters are set for each independent storage environment to delay the decay process of vegetables and fruits to the greatest extent possible, Extend the storage period of fruits and vegetables.

The modified atmosphere preservation device mainly consists of a modified atmosphere refrigeration unit, an air source unit, a preservation unit, an exhaust electric valve, and an audible and visual alarm (including a ventilation button).

The controlled atmosphere refrigeration unit mainly consists of a nitrogen generation module, an ethylene removal module, an ozone generation module, an electric control box, and a refrigeration module, etc., to achieve functions such as gas regulation (oxygen reduction, carbon dioxide reduction, ethylene removal, ozone sterilization), odor removal, temperature control, and humidity control in the fresh-keeping warehouse.

Our company can provide design calculations, construction, installation, and debugging services for the entire system. Our company can complete everything from the cooling capacity and storage capacity of the cold storage to the required air volume and the entire control system.

Participated in project: A modified atmosphere storage project for a certain Antarctic scientific research vessel.
