Fixed Gas Alarm Systems for the conservation and ripening process of fruit and vegetables
Ripening in controlled atmosphere Reliable monitoring of CO2 / C2H4 / C2H4O and O2 deficiency
Fresh fruit and vegetables are alive and continue to breathe after the harvest. This leads to oxygen consumption and the formation of carbon dioxide and water vapour. Keeping the products fresh means slowing down the process while maintaining the quality of the product. Gas sensors are just as important as the modern technology of the ripening chambers.
They are required to permanently monitor the various gas concentrations involved in the ripening process. The sensors, controllers and warning devices from MSR-Electronic protect people and equipment effectively and monitor the system as a central point of the entire process. Modern communication technology makes it possible to react quickly.
The innovative compact controller of the PolyGard®2 series from MSR-Electronic is de-signed for connecting up to 10 gas sensors via its own field bus, serves to warn of various gases and is therefore ideal for the application.
The process of banana ripening is probably the best known and consists of introducing ethylene into the storage room at concentrations around 150–200 ppm to accelerate the natural ethylene production of the banana itself.
