초록
▼

Liquid cryogen is added to a container of particulate material (e.g. powder, flakes or granules) immediately before the container is capped as part of a process for pressurizing the container. A liquid cryogen retainer is positioned within the unsealed container above the particulate material, and the flow of liquid cryogen is directed to the retainer to substantially prevent eruption from the container of the particulate material, which may otherwise result when the liquid nitrogen penetrates the particulate material and causes the particulate material ...
