High Capacity Sus304 Stainless Steel Chiller Blast Freezer Cryogenic Liquid Nitrogen Freezer
Product Description
Using liquid nitrogen for quick freezing not only has a very fast freezing speed, but also preserves the taste and nutrition of food to the utmost extent. In addition, nitrogen, as a gas in the air, is non-toxic, tasteless and very safe. In addition, compared with the tunnel-type quick-freezer, the cabinet-type machine occupies less area and is more convenient to use. It is more suitable for enterprises with low output and high product value.

The style
-Single-door cabinet freezer: Applicable to individual quick-freezing (IQF) and tray freezing. It is suitable for internal testing,developing and small-lot production. Small land occupation and low energy consumption.
-Double-door cabinet freezer: It is composed of two boxes, each box can be controlled separately, work alone, convenient for the situation that the quick-frozen food quantity is not full, only need to start one box to work, save the cost of liquid nitrogen. If two boxes are used at the same time, the exhaust gas can be used to precool each other.
-Multi-door cabinet freezer: It is composed of multiple boxes, each box can be controlled separately, work alone, If multiple boxes are used at the same time, the exhaust gas can be used to precool each other.
-Laboratory cabinet freezer: Commonly used in scientific research sites of schools and companies.

FAQ:
1,What is the refrigerant of DJL liquid nitrogen freezer? Is it safe? Do I need to go through any special procedures?
The refrigerant used in the DJL liquid nitrogen freezer is liquid nitrogen. Liquid nitrogen is separated from the air by cryogenic air separation technology. It is neutral and non-combustible and non-explosive. However, high concentration of nitrogen should be prevented from causing oxygen deprivation in confined Spaces; In addition, the limbs should not be placed in low temperature for a long time, nor can the limbs be immersed in liquid nitrogen, which will cause frostbite. Relative to others, liquid nitrogen is a relatively safe refrigerant.
It should be noted that when liquid nitrogen storage tank is used, it shall be submitted for approval for filing, which can be generally handled by the liquid nitrogen supplier.
2, Are you a manufacturer, trading company or a third party?
DJL reply: We are a manufacturer and we have established our own company since 2003.
