A picture of the ripening plant
The ripening plant in Hedel is one of the biggest in Europe – it consists of 81 banana ripening rooms (4 Grasso ammonia compressors). An innovation in this project is the direct ammonia pump system in the rooms – all rooms are directly cooled with ammonia (liquid). In the plant, each room's CO2, O2, and NH3 PPMs are measured.
To control and visualize the process of banana ripening, the Reliance SCADA/HMI system is used (Reliance Control Server). In addition, the process is monitored on iPads and iPhones via Reliance's thin clients. There is also an extra PC equipped with Reliance View that allows display on a big flat screen mounted in the conference room.
