VIII. DEODORIZATION WITH PLATINUM
8.1 DEODORIZATION WITH PLATINUM
8.1.1 This material is used for
Deodorization and defrosting because
of its high temperature acidification to
get rid of odors in the refrigerator.
8.1.2 This is a platinum-based catalyst
deodorant evenly coated on the
quartz tube. It is a highly active and
adhesive metal.
8.1.3 In the refrigerator, the odor passes by
the deodorant catalyst and is
attracted by the deodorant coated on
the quartz tube.
8.1.4 When defrosting, the 250°C-heat
produced in the quartz tube dissolves
the acidified odor and purifies the cold
air in the refrigerator.
8.1.5 After defrosting, the clean and odor-
free cold air refrigerates the food. At
the next defrosting, it carries out
Deodorization and this process is
repeated.

8.2 APPLICATION OF PLATINUM AS
DEODORANT
8.2.1 A fan is used in the frost-free refrigerator
for refrigeration.
8.2.2 The Platinum deodorizer is installed
beneath the cooler at the cold air outlet
that cools the freezer compartment.
Because the refrigerator is a sealed
cabinet, the rotating cool air is forced to
rotate by the fan and cause odor to pass
through the deodorizer.
8.2.3 When not defrosting, the deodorant is
highly activated and odor is absorbed.
8.2.4 After running for a while and during the
defrosting stage, the heat produced by the
defrosting heater that goes through the
quartz tube to the deodorant on the
surface at over 250°C, causes odor to
attach to the deodorizer where it is
acidified into pure gas, free of odor.
8.2.5 At the end of defrosting, the fan resumes
work and the high temperature does not go
down. The acidified gas causes the
deodorant to continue to absorb odor.
