Fruit-vegetable box applicable to air-cooling refrigerator and rapid-cooling and moisturizing method of fruit-vegetable box

Abstract

The invention discloses a fruit-vegetable box applicable to an air-cooling refrigerator. The fruit-vegetable box comprises a box body, wherein a spraying device is arranged at the top in the box body; an air inlet is arranged at the upper part of the front side of the box body; an air outlet is backwards and convexly arranged at the lower part of the rear side of the box body and is communicated with an air duct of the refrigerator; the tops of the rear ends of the air inlet and the air outlet are respectively hinged with a wind board; and the wind boards are used for blocking the air inlet and the air outlet. The invention also discloses a rapid-cooling and moisturizing method of the fruit-vegetable box applicable to the air-cooling refrigerator. The fruit-vegetable box is provided with the air outlet connected with the air duct of the refrigerator, so that high-humidity gas in the fruit-vegetable box is directly conveyed out by the air duct of the refrigerator, and is prevented from entering a refrigerating chamber and further promoting the frosting phenomenon in the refrigerating chamber. The spraying device can carry out spraying and over-humidifying treatment on fruits and vegetables in advance, the circulating air of the refrigerator can carry out evaporation and cooling on the fruits and the vegetables, so that not only is rapid cooling of the fruits and the vegetables realized, but also high humidity of the fruits and the vegetables is maintained, and simultaneously, the frosting phenomenon in the refrigerating room can not be promoted.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable preservation, in particular to a fruit and vegetable box for an air-cooled refrigerator and a quick cooling and moisturizing method thereof. Background technique [0002] Postharvest physiology believes that due to the high water content in fruits and vegetables, the humidity is often close to saturation, so the evaporation of water depends on the temperature and relative humidity of the product and the environment. The higher the temperature, the greater the water pressure difference inside and outside the fruits and vegetables, and the faster the water evaporates. Therefore, air-cooled refrigerators that use forced convection circulating air to achieve rapid cooling are popular, but circulating air will cause stored foods (especially fruits and vegetables) to lose moisture very easily. Simultaneously cooling fruits and vegetables (or other foods) rapidly and maintaining high humidit...

Problems solved by technology

[0003] Chinese patent 201110056257.5 discloses a moisturizing air-cooled refrigerator, which proposes to use partitions to block the cooling circulation air from entering the refrigerator to ensure humidity. The disadvantage is that due to the lack of forced cooling air source, the cooling speed of fruits and vegetables is slow, and the water evaporation is still relatively fast.

Chinese patent 201110085887.5 discloses a method for increasing the humidity in the box for air-cooled refrigerators, and air-cooled refrigerators. It is proposed to use return weathering and defrosting to supplement the humidity requirements of fruits and vegetables in the box. The disadvantage is that it is limited by the timing of defrosting and the average humidity is difficult to achieve. More than 90%, the fruit and vegetable preservation effect is only slightly improved

Chinese patent 200920255463.7 discloses a humidifying and fresh-keeping device for refrigerators, and Chinese patent 200710006070.8 discloses a method and device for controlling humidification in refrigerators and refrigerators, as well as refrigerators equipped with such devices, all of which propose that a humidifying device be installed in the refrigerator to ensure that fruits and vegetables have 85%-95% relative humidity. Ambient humidity, its disadvantage is that "losing water and replenishing moisture" will cause the illusion that fruits and vegetables look new but not fresh in quality. water phenomenon

At present, there is no fruit and vegetable box suitable for air-cooled refrigerators that can not only achieve moisturizing and rapid cooling of fruits and vegetables, but also use the existing structure of air-cooled refrigerators to avoid aggravating the phenomenon of frosting in the refrigerator. "Pre-humidification" and a quick cooling and moisturizing method to ensure that the humidity in the fruit and vegetable box is maintained above 99% for a long time
