Relevant scientific data indicate that in the cold storage temperature range of 2 to 8°C, vegetables, fruits, eggs, beer, and beverages can maintain their freshness and original flavor. At 0°C to 2°C, food is stored without freezing, preserving nutrients and keeping items like fresh fish and meat fresh for up to 1-2 days. In variable temperature zones ranging from -2°C to -14°C—such as water temperature storage (-2°C to -3°C), micro-freezing (-3°C to -5°C), soft freezing (-6°C to -8°C), and mild freezing (-10°C to -14°C)—foods retain their nutritional value and taste. In the deep-freeze zone at -18°C to -21°C, meats, fish, and frozen foods can be stored for extended periods with faster freezing and longer preservation.
Rongshida has developed a health-conscious, energy-efficient, intelligent refrigerator that features four distinct temperature zones, allowing for tailored storage solutions that enhance the freshness and quality of different types of food.
When using the refrigerator compartments:
a. The freezer compartment maintains a temperature around -18°C, ideal for storing fresh or frozen meat, fish, poultry, and cooked foods. This area can preserve items for about three months and quickly freezes fresh food to maintain maximum freshness.
b. The refrigerating compartment operates at approximately 5°C, suitable for both raw and cooked foods. The storage duration is typically around one week. Fruits and vegetables should be placed in dedicated fruit and vegetable drawers (at 8°C) and wrapped in plastic to extend their shelf life.
c. The ice temperature preservation room, located in the upper part of the refrigerating chamber, maintains a temperature of about 0°C. It is perfect for storing fresh meat, fish, shellfish, and dairy products without freezing, keeping them ready for use within three days. This area can also serve as a thawing zone for frozen foods. Placing frozen items here before work allows them to be used immediately after work.
d. Some refrigerators include a versatile greenhouse compartment, where users can adjust the temperature based on their storage needs. If the regular cooling compartment is insufficient, this area can be set to refrigeration mode. It is also useful for thawing frozen foods, especially when kept in fresh-keeping conditions for convenience.
Food storage tips:
a. Before storing any food, allow the refrigerator to run empty for about two hours to ensure the internal temperature stabilizes.
b. Avoid overcrowding the fridge. Leave space between items to allow proper air circulation and even temperature distribution.
c. Allow hot food to cool before placing it in the refrigerator to prevent affecting the taste of other items and to reduce energy consumption.
d. Store animal-based fatty foods like ice cream and fish in the freezer compartment, not on the door shelves or near the entrance, as these areas tend to be warmer.
e. Avoid placing liquid beverages such as beer, orange juice, or water in the freezer, as they may freeze and potentially burst.
