Filed:

Appl. No.:

7/105477

Inventors:

Louis P. LaBarge - Vista CA

Assignee:

LaBarge Universal Ripener, Inc. - Norfolk VA

International Classification:

A23B 7152

US Classification:

426312

Abstract:

A fruit ripening system wherein a continuous inflow of fresh air and ethylene gas is provided into a fruit ripening chamber in correct proportions to form a fruit ripening gas mixture that will predictably ripen fruit in a very short period of time, regardless of the previous state of ripening of the fruit. At the same time, the ripening chamber is continuously purged of carbon dioxide that is a byproduct of the ripening process so that during the ripening process a concentration of carbon dioxide sufficient to materially impede the ripening process is never allowed to build up. Critical parameters are defined for ripening temperature, the minimum ethylene gas concentration, time of exposure to the ethylene gas, and purging of carbon dioxide.
