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.
