The Rigid Dose
Cryotech International introduces liquid nitrogen (LN2) dosing systems
The IntroDoser from Cryotech International is one of the ideal introductory liquid nitrogen (LN2) dosing systems. Designed specifically for product testing purposes, pilot facilities and infrequent, low speed production runs, the IntroDoser offers precise, affordable dosing. Typically installed after the filler and before the capper/sealer, it dispenses a measured dose of LN2. Once the LN2 in introduced into the container, it immediately picks up heat and turns into gaseous nitrogen, expanding 700 times in the process. When trapped inside the container, the gaseous nitrogen creates pressure and adds rigidity to the container. For headspace inerting applications, the rapidly expanding gas is allowed to escape before the product is sealed, flushing oxygen out of the container.
The IntroDoser's semi-automatic operation requires manual filling of the 3 litre reservoir. Once prepared for production, the IntroDoser operation is completely automatic. A system sensor detects the presence of a container and delivers a dose of LN2.
