Inex Partners Oy, Finland
In 2013, Inex Partners decided to build a new distribution center for Finland. Four years later, the enormous size of the center allowed building 40 ripening rooms, of which 13 rooms are used for 24 pallets of bananas, 24 rooms for 40 pallets of bananas, and 3 rooms for 24 pallets of exotic fruits (mangoes, avocados, papayas).
All ripening rooms are cooled with a water-glycol solution provided by a large cooling plant on site. Extra-low–temperature glycol is used for ripening the exotic fruits.
In 2017, a system designed to visualize and control the ripening process was installed by the Dutch company De Laat Koudetechniek.
WINNING INSTALLATION
This installation finished first in the Reliance Success Story Awards 2017 competition.
The control system consists of Siemens SIMATIC S7-1200 PLCs and the Reliance SCADA/HMI system. The whole Reliance project is based on templates, which allow the operating personnel to dynamically switch between visualization windows.
To measure air in all ripening rooms, a hose is connected from each room to a central control cabinet, which sucks air out of the room into the cabinet where it is analyzed by three sensors:
This data is transmitted between the central measurement PLC and the ripening room PLCs over TCP/IP.
Also, a Ripe-Pro gas mixing unit is installed at the distribution center. It is used to extract nitrogen from the air and to mix it with pure ethylene. The resulting mixture (4% ethylene, 96% nitrogen) is supplied to the ripening room (4 % is the maximum allowed because of explosion and toxic hazards).
