Precise control of temperature, humidity and light is the magic weapon of the refrigerator
As we all know, refrigerators can keep vegetables and fruits fresh, have refrigeration and freezing capabilities, and are suitable for a variety of purposes. In general, the refrigerator performance is reflected in the food preservation technology, food preservation can be divided into three stages: 0 - 5 degrees, known as the physiological freezing period. At this time, the cell fluid forms a large amount of ice crystals, and the ice crystals pierce the cell wall. Most of the nutrients in food are lost when they are frozen. -6―-18 degree is called frozen preservation period. Water in the food may be lost. -19―-24 degrees is called solidification preservation period. Water and nutrients in food in this state will not be lost.
Light, temperature and moisture are the most essential elements necessary for plant growth and development. For the fruits and vegetables stored in the refrigerator, the large temperature fluctuations in the box and the lack of moisture in the air will greatly shorten the freshness of fresh fruits and vegetables. The lack of light will also hinder the normal life metabolism of fruits and vegetables. Therefore, how to provide good temperature, humidity, and illumination is the key to reflecting the quality of refrigerators. We can also monitor the temperature, humidity, and illuminance in the refrigerator by using a temperature illuminometer and a temperature and humidity recorder. The temperature and humidity self-recording instrument is used to measure the temperature and humidity, the recording and display temperature range is -40 °C ~ 120 °C, the humidity range is 0 ~ 100% RH; and the temperature illumination meter's illuminance determination range is 0- 40,000Lux. Therefore, it can meet various environmental parameters in the refrigerator box.
The optimum temperature, storage area and storage time of different foods are different. The refrigerator with good quality adopts multi-cycle technology, the temperature of each storage room is controlled independently, and the temperature is controlled at the set value, so that the humidity control in the refrigerator is more accurate. Allowing a variety of foods to be as fresh also enables foods to reach temperatures below -18 degrees at a very fast rate, so that nutrients and moisture in the food are lost as little as possible. In addition, some new refrigerators are also placed in the box of colorful light, can irradiate vegetables and fruits, so that fruits and vegetables can continue to photosynthesis synthesis of nutrients, so that fruits and vegetables continue to grow in the refrigerator, thus greatly extending the preservation effect. In addition, when using the refrigerator, we can use the temperature and humidity recorder to sample and measure the temperature and humidity in the refrigerator at any time, so as to keep abreast of the preservation status of the refrigerator and keep the freshness of fruits and vegetables for longer.
