How to Use Nitrogen Tanks for Fast Cooling?

Rapid cooling is an industrial process that allows cooling of products and materials at very low temperatures. This technique has been developed to accelerate production, provide better quality, reduce costs and improve other aspects in the industry. In fact, rapid cooling has become an important part of many industrial processes.

In many cases, rapid cooling involves the use of nitrogen tanks to reduce temperature. These tanks are contained in large stainless-steel containers, which are filled with compressed nitrous oxide at pressures higher than 25 MPa (Millions of Pascals). In this respect, gas cooling provides a fast way to cool down, as the diffusion rate of gases is very high.

Why is nitrogen widely used for rapid cooling?

The use of nitrogen has been proven as a safe and reliable way to cool materials, since it is an extremely versatile cold source, being able to reach very low temperatures (-196ยฐC), is safe and stable, and is also inert, non-corrosive and odorless, making it a perfect medium for rapid cooling, without leaving any sign of its use.

When nitrogen is mixed with water, the mixture expands considerably, forming a large volume of nitrogen vapor, which allows extremely rapid cooling. The interaction of these two substances requires a specially designed water supply system that gives the mixture sufficient time to expand, and be directed to the system to be cooled.

What are the applications of fast cooling at an industrial level?

Rapid cooling with nitrogen has numerous industrial applications, although most of them focus on refrigerating edible products such as fruits, vegetables, dairy and meats, some are even used to solidify certain raw materials, such as rapeseed oil, instead of refrigerating. Nitrogen has been shown to be effective in maintaining the freshness of these products while reducing the presence of microbes.

In addition to refrigerating edible products, nitrogen is also used to cool other products, such as metals, plastics, and chemicals. These applications require the exact specification of the temperature appropriate to the process and the amount of nitrogen needed to achieve it. In this way, nitrogen has found multiple uses in different areas of industry.

In general, the use of nitrogen tanks is an excellent way to achieve the fast cooling required for many industrial applications. When choosing the right equipment, you should take into account the desired temperature, the amount of nitrogen needed to reach it and make sure that the safety equipment is properly configured.

How are liquid nitrogen fast cooling systems designed?

Nitrogen fast cooling systems are built from several major parts. The first component is the nitrogen tank, which contains the necessary amount of compressed nitrous oxide. The second component is the nitrogen and water mixing system, which includes a hose, a pump, and a device to control fluid pressure. The third component is the control equipment, which is responsible for controlling the temperature as well as the operation of the mixing system.

With these three main parts working together, the fast cooling required for the application is provided. A fast-cooling system with nitrogen also requires some additional safety equipment to avoid any safety risk. This equipment includes safety thermometers, flow scales and containers to collect any excess liquid. Such equipment must be carefully selected and monitored to avoid future unnecessary hazards.
