The Techinjector® is ideal for packaging lines that need an inert nitrogen gas to provide slight container pressurization or where nitrogen gas can extend the product life and freshness. Injecting a small drop of liquid nitrogen into a container displaces air and replaces it with inert, odorless nitrogen gas. If the liquid nitrogen is injected just before container sealing, slight container pressurization can be achieved making thinner containers easier to process and handle.
Bottlers of noncarbonated soft drinks, juices, water, wine and beer often use LN2 injection equipment to insert small measured drops of LN2 into their containers.
Processors of nuts and other perishable items use LN2 to provide an inert atmosphere in containers.
Soft food packages can be pressurized by liquid nitrogen injection to protect the package contents from crushing.
Pharmaceuticals and supplement industries use liquid/gaseous nitrogen in packaging products.
Liquid nitrogen expands 700 times in volume when changing from liquid to gas. By injecting a small amount of liquid nitrogen just before the container is sealed, the expanding nitrogen gas will displace the air in the container. This creates an oxygen free (inert) environment to extend product life and can give a slight pressurization to thin wall packages if needed to improve container durability.
A continuous stream liquid nitrogen injection can be wasteful at slower line speeds and will not detect missing containers or the complete lack of containers on the packaging line. Technifab’s Techinjector, using a sensor on the packaging line, detects each container and precisely injects a measured dose of liquid nitrogen at the proper time. The Programmable Logic Controller (PLC) unit automatically adjusts for line speed changes and does not dose missing containers. The unit can also be set up to run in a continuous mode and then shut off when containers stop coming down the production line.
The Techinjector body is vacuum insulated to eliminate frost or ice build-up around the unit. A small amount of nitrogen gas flow eliminates moisture build-up at the dosing point. There is a heater at the dosing head to eliminate icing and the resulting problems some other injectors have. An injector actuator unclamps in minutes and nozzles can be changed in seconds, allowing quick change-out of components that might wear on the unit.
The control box can be remote mounted from the injector body, reducing line space and making changes to the unit easier for operators. Up to 6 different settings can be stored in memory. Customer container changes on the line are only a few keystrokes away.
The Techinjector® is very compact: 17” (43 cm) tall and 11” (30 cm) wide
