CryoDoser automatic liquid nitrogen fi lling system is designed to inject LN2 into containers  at  required  pace.  After  fi lling  into  container,  liquid  nitrogen vaporiz-es to nitrogen gas and expel air out of container. As a result, oxygen and humidity concentration are reduced, and a suitable pressure is built in container.

• Siemens touch screen controller and PLC platform, fully automatic operation

• Adjustable filling pace, up to 1200 CPM in discrete dosing mode or 2000 CPM in continuous injection mode.

• Speed sensor: real-time detection of bottle movement speed,  filling speed will be adjusted accordingly.

• Product sensor: installed at upstream of the fi lling machine, detecting whether bottle is coming. If no bottle coming, liquid nitrogen will not be injected to avoid waste.

• Electric heating at nozzle, prevent condensation water and freezing ice. 3 sizes nozzles are supplied as standard, customized nozzle available.  

• Gas-liquid separator to guarantee liquid nitrogen is injected.

• Vacuum insulation for low liquid nitrogen consumption.

• Imported high quality electromagnetic valve for high reliability.   

•  Stainless steel SUS304 material for easy cleaning and no rust.

• Inert packaging (low oxygen concentration) maintains product freshness and extends product shelf life.    Reduce the gram weight of PET, lower cost and more environmentally friendly.

• Maintain the original shape of lightweight bottle, keep the hardness of the bottle wall consistent, and improve    labeling ef ficiency.

• Build a suitable bottle pressure and eliminate the problem of flat bottles.

• Enhance product stacking capacity and improve warehouse space utilization.    

• Maintain the high quality of organic products.
