What about the details for Liquid nitrogen blast freezer?
Liquid nitrogen, liquid nitrogen. It is inert, colorless, odorless, noncorrosive, nonflammable and extremely low temperature. Nitrogen makes up most of the atmosphere (78.03% by volume and 75.5% by weight). Nitrogen is inert and does not support combustion. A large number of heat absorbing contacts are injured during vaporization. Nitrogen accounts for 78% of air. Under normal pressure, the temperature of liquid nitrogen is – 196 ℃; one cubic meter of liquid nitrogen can expand to 696 cubic meters of pure gaseous nitrogen at 21 ℃. Liquid nitrogen is a colorless, tasteless, low-temperature liquid and gas under high pressure. Liquid nitrogen (LN2) is a liquid form of nitrogen formed at low temperature. The boiling point of nitrogen is – 196 ° C. under normal atmospheric pressure, if the temperature is below this, liquid nitrogen will be formed; if pressurized, liquid nitrogen can be obtained at a higher temperature. In industry, liquid nitrogen is obtained by air fractionation. After the air is purified, it is liquefied under pressure and cooling, and separated by different boiling points of each component in the air. There is no problem when the human skin directly contacts with liquid nitrogen. It will be irreversible after more than 2 seconds.
Liquid nitrogen blast freezer is suitable for fresh, seafood, fish and shrimp, meat, medicine and other high value-added food. Suitable for IQF and pan freezing, suitable for internal test, development and small batch production; small land occupation and low energy consumption. In actual production, due to differences in food and technology, the actual capacity may be higher than the preset capacity. Can follow up the customer’s request to customize all kinds of equipment suitable for the customer’s site specifications. According to the customer’s requirements, we can flexibly design the partition module to achieve small energy consumption, and one machine can run different processes and process different products at the same time.
Liquid nitrogen freezer is suitable for the assembly line production of high value-added food in large batch, continuous, less humanized and large industrial production mode, such as processing fish and shrimp, shrimp, seafood, river fresh, fresh, meat products, top-grade fruits, seasoning bags, anti season fruits, medicinal herbs and other large-scale food products, which can be combined with other food lines into automatic lines.
