Ethylene Ripening System

Automated System with Ethylene and Carbon Dioxide Removal


Completely automated ripening systems which is also called as centralized ripening system consists of :
  • Gas Cylinder Bank
  • Gas analyzers
  • Centralized ripening controller.

Ripening is done completely by the system automatically. It controls the complete ripening cycle of 4 days and no user intervention is require. The controller activates the ripening cycle by a simple switch which starts the ripening cycle. It doses the room with ethylene for 16 to 24 hrs which can be set by the user. It measures and doses the room continuously to maintain is to 100 ppm. For the next 3 days the CO2 is controlled and maintained below 1 % levels. It controls the CO2 levels using ventilation fans or CO2 scrubber. The system is controlling all the parameters which are required of ripening hence every batch coming out of the system is uniform and consistent over a period of time. This is the ultimate goal of the customer.

The Procedure:
  • Precool the banana to 18 to 20 degrees
  • Switch on the ripening controller
  • Open the door after 4 days
