Operation
Rapid Cooling Process
This program can quickly reduce the temperature of cooked food from 194°F to 37°F in 90 min-
utes, avoiding the critical temperature range of 46°F to 154°F that can cause spoilage. Quick-cooled
cooked food can be stored in the refrigerator at 37°F for up to ve days.
Quick-Freeze Program
The quick-freeze program rapidly reduces the temperature of food from 194°F to 0°F in 240 minutes,
preventing the formation of ice crystals and thereby minimizing juice and vitamin loss. This procedure
is suitable for both cooked and raw foods. Frozen cooked and raw foods can be stored at 0°F for up
to 2 months and 12 months, respectively.
Save Program
Once the quick-cooling or quick-freezing process is complete, the machine automatically shifts into a
preservation mode to maintain the food’s core temperature. In this phase, the machine operates like a
standard refrigerator. However, it is not recommended for long-term storage.
Food Storage Guidelines
For optimal performance during the Save Program stage:
• Do not place hot food or uncovered liquids in the machine.
• Wrap or cover foods, especially those with strong aromas.
• Arrange food properly to ensure good air circulation. Avoid placing food on paper trays, cardboard,
or wooden boards, as these can block airow.
• Minimize the frequency and duration of door openings.
During the Quick-Cooling or Quick-Freezing Process stage:
• Do not open the door from the beginning to the end of the program.
• To achieve optimal quick-cooling and quick-freezing eciency, start the machine at the lowest
temperature and let it run for 20 minutes before placing food inside. This also enhances the ma-
chine’s low-temperature sterilization effect.
• Avoid covering food with lids or placing it in closed containers. Use plastic wrap or other methods
to prevent splashes when placing food into the machine.
• Do not use trays or containers deeper than 2.5 inches.
• Do not stack food; the thickness should be less than 1.6 inches.
• Use aluminum or stainless steel containers without lids.
