Appliances 4 Less springfield offers residents of Bolivar, aMarshfield, Willard, Nixa and Seymour a selection of opened, scratched and dented appliances that are perfect for your summer living. Here is our guide to the must-have appliances for a cozy summer home.

The freezer, the magician of time in the modern kitchen, weaves the dialogue between ingredients and time for us through two completely different methods of freshness preservation and freezing. Today, let us have an in-depth understanding of the freshness preservation and freezing of the freezer, and feel how technology can bring a new freshness preservation experience to our dining table.

1、 Temperature control and range

Temperature is the core factor that determines the freshness of ingredients. Let us deeply understand the mysteries of temperature under the two conditions.

(1). Preservation

①. Precise temperature control system

Modern fresh-keeping technology uses multi-point temperature sensing technology, just like installing sensitive temperature nerve endings on a freezer. These sensors are cleverly distributed in every corner of the storage room, which can monitor temperature changes in real time and accurately, and strictly control the temperature difference within ± 0.5 °C. Once there is an abnormal temperature in a certain area, the system will quickly activate the compensation mechanism to restore the temperature balance through precise air-conditioning flow, ensuring that the ingredients in every corner can enjoy a suitable temperature.

②. Dynamic temperature regulation

The smart chip will automatically cool the power according to the temperature and the amount of food stored. In hot summer, the system will automatically enhance the cooling effect; When there are many ingredients stored, the refrigeration will be appropriately increased. This dynamic adjustment not only ensures the freshness preservation effect, but also realizes the rational use of energy.

(2). Freezing

①. Deep freezing technology

Relying on a powerful compressor and a high-efficiency condenser, freezing can quickly exert force with super efficiency, and the temperature can be severely reduced to the extreme cold of-24 °C in a short period of time. At such a low temperature, the metabolism of microorganisms is almost stagnant, which has built a solid and reliable line of defense for the long-term preservation of ingredients.

②. Layered temperature control management

The freezer implements fine layered temperature control, and the upper layer temperature is slightly higher, which is specially customized for ice cream and other foods that do not require strict low temperature; The middle layer has a stable temperature, making it perfect for frozen staples; The low temperature of the lower layer is strictly controlled to ensure the freshness of meat and seafood. This design accurately matches the needs of ingredients, improves the freezing efficiency, and is convenient and efficient to use.

2、 Functional design and technology

(1). Fresh-keeping special functions

①. Intelligent humidity control

Through the collaborative work of the humidity sensor and the atomization device, the freezer can produce humidity for different ingredients. The system will automatically monitor the humidity change, and when the humidity is insufficient, the humidification system will be activated in time to replenish moisture for the ingredients; When the humidity is too high, the dehumidification program will be started to prevent the ingredients from rotting and deteriorating due to excessive humidity.

②. Zero-degree fresh-keeping space

The temperature is controlled between-0.5 °C and 0.5 °C through precise algorithms, so that the ingredients are slightly frozen without freezing. This temperature range can not only effectively inhibit the reproduction of bacteria, but also has no cellular structure. It is especially suitable for preserving some high-end ingredients on temperature, its taste and flavor.

(2). Freezing features

①. Rapid freezing technology

The high-power refrigeration system cooperates with high-efficiency heat-conducting materials, so that the central temperature of the ingredients can quickly drop below-18 °C. During this process, the water inside the ingredients will form tiny ice crystals that will not pierce the cell walls. When thawed, the cell sap is not lost in large quantities, thereby preserving the original taste and nutrients of the ingredients to the greatest extent.

②. Intelligent defrosting system

Through the frost layer thickness sensor, automatically judge the time of defrosting. When the frost layer reaches a certain thickness, the system will start the reverse cycle defrost technology, and use the heat generated by the compressor to quickly melt the frost layer. The whole process only takes ten minutes, and the refrigeration resumes immediately after the end.

3、 Health and Safety

(1). Preservation

①. Application of antibacterial materials

The liner is made of silver ion antibacterial material, which can effectively inhibit the growth of common pathogenic bacteria such as Escherichia coli and Staphylococcus aureus. Experiments have proved that the antibacterial rate of this antibacterial material can reach more than 99% within 24 hours. At the same time, the materials of all ingredients meet food-grade standards to ensure that they will not contaminate the ingredients.

②. Intelligent early warning system

When the temperature is abnormal, the system will sound an alarm through sound and light; When the door body is not closed tightly, it will be reminded in time; When the equipment fails, it will automatically diagnose and prompt for repair. These intelligent early warning functions ensure that ingredients are always safely stored.

(2). Freezing

①. Deep low temperature antibacterial

Below-18 ℃ can effectively inhibit most microbial activities. At this temperature, the bacteria's metabolism almost stops and they can't reproduce. Ingredients stored at this temperature are still safe to eat after several months. This low temperature provides a reliable guarantee for the preservation of ingredients.

②. Power-off protection function

The freezer is equipped with a high-performance insulation layer and a cold storage agent, which can still maintain a low temperature for a long time even if the power is cut off. When the power supply is restored, the system will automatically detect the temperature in the box and quickly restore to the set temperature.

Conclusion

The freshness preservation and freezing of the freezer have their own advantages and disadvantages, and complement each other. Fresh preservation relies on its precise temperature control and delicate functional design, so that the ingredients are always in state, as if time has slowed down in front of it; Freezing relies on its powerful freezing capacity and perfect safety guarantee to realize food storage and provide more convenience for your life.
