Abstract

See full text

A system for reducing oxygen in a package of produce product using a lance manifold. The lance manifold has a first end adapted to receive an input gas flow and a second end adapted for placement in a partially-enclosed cavity containing the produce product. The second end of the lance manifold includes a plurality of exit ports adapted to produce an output gas flow and a sampling port for taking an air sample from the partially-enclosed cavity. The system also includes an oxygen analyzer for detecting oxygen content of gas inside the partially-enclosed cavity using the sampling port. The system is configured to produce an output gas flow with the following properties: a substantially oxygen-free composition; a flow rate of at least 100 standard cubic feet per hour (SCFH); and a flow direction substantially 90 degrees to a cavity opening of the partially-enclosed cavity.
