Food storage industry

liquid oxygen nitrogen plants are used in food storage to rapidly freeze food, preserving its nutrients, texture, and flavor by minimizing ice crystal formation that can damage cell structure. This process also extends the shelf life of food by preventing the growth of microorganisms, making it ideal for perishable items like fruits, seafood, and meat.

Laser cutting industry

In laser cutting, liquid nitrogen serves as a cooling medium to reduce the temperature of the material, minimizing the heat-affected zone, preventing deformation, and avoiding burn marks, which ensures precision and high-quality cuts. It also accelerates the cutting process, reduces oxidation on the surface, and protects the laser equipment from overheating, thereby extending its lifespan.

FAQ

Q: What is your delivery time?

A: Usually, it takes 60 to 90 days after receiving the advance payment.
The specific delivery time depends on the items and quantity of the order.

Q: Can you produce according to customer requirements?

A: Yes, we can produce according to your requirements or technical drawings. We can make molds and fixtures.

Q: What is the relationship between the Cryogenic process and the Distillation process in liquid nitrogen production?

A: The Cryogenic process cools and liquefies air to extremely low temperatures, creating the necessary conditions for separation. The Distillation process then takes place at these cryogenic temperatures, where nitrogen and oxygen are separated based on their different boiling points. By combining both processes, large-scale and high-purity liquid nitrogen production becomes possible.

Q: What is the ordering process?

A: (1) Inquiry --- Provide us with all clear requirements.
(2) Quotation --- Official quotation sheet with all clear specifications.
(3) Contract confirmation --- Provide correct contract details.
(4) Production --- Mass production .
(5)Transportation --- Sea.

Q: How does a liquid nitrogen plant work?

A: In a cryoplant's liquid nitrogen generator, atmospheric air is pressurized by a compressor and fed into a buffer tank. From the buffer tank, this air is channelled towards a set of filters behind the cryoplant to remove impurities. Any remaining moisture is eliminated by an internal air dryer unit.

Q: How does Large Size Liquid Nitrogen Plant ensure the stability of production capacity? How long can the equipment run continuously?

A: This device is equipped with redundant refrigeration system and intelligent load balancing technology. When some components have temporary failures or load fluctuations, it can automatically adjust to ensure the continuous and stable output of liquid nitrogen.

Q: What energy-saving measures does this device have to help us control costs?

A: The device adopts an efficient heat recovery system, which can recycle and reuse the waste heat in the production process. The precise temperature control system can intelligently adjust the liquid nitrogen output according to the actual working conditions to avoid energy waste.

Q: Can the purity of the produced liquid nitrogen meet the medical standards?

A: We use multi-stage distillation and deep purification technology to produce liquid nitrogen with a purity of more than 99.999%, which far exceeds the general industry standards. It can provide reliable protection for your high-precision scientific research work such as biological sample preservation and cell research.
