Liquid nitrogen dosing systems for oxygen reduction
LN2is supplied to the doser by a vacuum insulated hose and flows into the dosing head. A sensor detects the speed of the line (encoder compatible for higher speeds); a second sensor detects the presence of a container. When a container is detected, the dosing head opens and dispenses an exact amount of pure LN2. The LN2 gasifies and is either trapped in the container to add rigidity or escapes with oxygen to inert the headspace.
