Abstract: A cell for degassing of residual olefin oxide from an olefin oxide sterilized product. The product is fed through the cell on a gravity conveyor using a combination of heat, retention time and air change rate optimized for a particular product. A pallet containing the product to be degassed rolls to a preselected position within the cell. The pre-selected position is established by automatically controlled stops appropriately located on the gravity conveyors. The cell is dedicated to a specific sterilizer product load and can be arranged in a modular fashion with a minimum internal volume.
