ABSTRACT:
Ethylene is a gaseous growth hormone produced by plant which triggers the ripening of fruits and vegetables. Titanium dioxide, positioned on a filter, acts to trap ethylene to remove the ethylene from a vegetation storage container. Sodium silicate is utilized to absorb moisture to reduce the absorption of moisture by the titanium dioxide to prolong the ethylene trapping capacity of the titanium dioxide. The filter, after becoming saturated to a desired extent with ethylene, is removed from the vegetation storage container and heated to facilitate a release of the ethylene from the titanium dioxide. This process provides for a reconditioning of the filter for continued use within the vegetation storage container. Producing an air flow and providing for exhaust of ethylene enhance the reconditioning of the filter during the application of heat.
