Abstract
Apparatus and method for exposing product to a controlled environment. The apparatus includes a distribution chamber with an inlet for receiving controlled environment or combination of gases, and a region of flow resistance. A plurality of jet nozzles are surrounded by the flow resistance region and provide high velocity streams of controlled environment which are surrounded by the low velocity streams from the resistance region. For some applications, a section of chamber immediately preceding entry into a sealer, the controlled environment supply to the jet nozzles may be shut off.
