X. Storage essentials
Before storing articles, please keep the freezer running in empty state. When the freezer is running
stably (it is best to keep it running in empty state for 5 hours above) and the inside is cooled completely,
the cold store articles can be put in.
Articles or other products put in the freezer in one time shouldn’t be too much. Proper clearance should
be left to help the circulation of the inside cold air.
The refrigerating system of the ultra low temperature freezer is a device used for maintaining low
temperature rather than a quick freezing device. If you want to store high capacity (high water-bearing
material), pre cooling them in other quick-freezing plant and then store them in the freezer to avoid
long-time running without stop of the refrigerating system.
When the initial storage capacity is large, a method of gradually lowering the temperature set should be
adopted. The temperature is lowered by 10
℃
in every step and then maintained for 1-2 hours until the
storage temperature is reached.
When storing plastic bag products, please note that do not get them close to metal edges to avoid
scratch of plastic bag.
