METHOD FOR EFFECTIVE DE-OXYGENATION OF PRODUCT CONTAINERS FOR USE AS CONTAINERS FOR OXYGEN SENSITIVE PRODUCTS |
摘要 |
The invention generally relates to the use of liquid nitrogen to displace air, or other water and/or oxygen containing atmospheres, from containers prior to filling with a highly sensitive product. The process in general has two steps: a) depositing a volume of liquid nitrogen into the cavity of an empty container and b) applying a vacuum to the cavity of the container. The vacuum will accelerate vaporization and thereby shorten the liquid nitrogen vaporization time frame. This procedure results in a highly effective one step de-oxygenation and/or de-humidification of the container cavity. Further, the evacuation ensures complete liquid nitrogen vaporization prior to product filling. |
