Problems solved by technology

However, cooked food is often sold directly in a room temperature room, and it is possible that the cooked food bought back has been contaminated by a large number of microorganisms
In addition, if the leftover food at home is stored in the freezer of an ordinary refrigerator, it will face problems such as color change and cross-contamination

Embodiment 1

[0030] Example 1: When cooked food is stored in compartment 1 of the refrigerator, including cooked meat, cooked vegetables, rice and other foods, if all these foods are placed in the large cold room of the refrigerator, not only will it cause mutual odor and cross-contamination between foods, It can't meet the optimal storage temperature, humidity, gas and other factors of cooked food, resulting in rapid loss of nutrition and short shelf life of food. Put the above-mentioned cooked food into the refrigerator compartment 1 of this application. The freezing point temperature of most of the cooked food is between -3°C and 0°C. Within this temperature range, the cooked food can not only maintain the original flavor and nutrition, but also effectively prolong its life Fresh-keeping period: the fresh-keeping humidity of cooked food should not be too high or too low, as long as the original humidity is kept without loss, and the reduction of oxygen content can delay food spoilage, so...

Embodiment 2

[0031] Example 2: When fresh meat is stored in compartment 1 of the refrigerator, if it is slaughtered and sold directly in the morning, it needs to be put in the temperature range of 2-4°C for deacidification before eating, more It is conducive to the absorption of the human body. After deacidification, it is stored in a temperature zone of about -3°C. It can be cut directly without thawing, and it can also effectively extend the food preservation period and maintain its quality; 80%-90% humidity is conducive to freshness Meat forms a layer of water film during storage, which is conducive to the maintenance of its sensory quality; the sterilization and deodorization device prevents the growth of bacteria on the surface of fresh meat; experiments have proved that the electric field strength is between 50 and 1000V / m (that is, the space electric field device 7 The discharge source is installed at a distance of 5-50cm from the compartment), which is more conducive to inhibiting t...

Abstract

The invention discloses a refrigerator fresh-keeping device based on gas adjustment, and relates to the technical field of refrigerator fresh-keeping. In the refrigerator fresh-keeping device, air inlets are formed in the upper parts of corresponding refrigerator compartments; return air inlets are formed in the lower parts of the corresponding refrigerator compartments; substrate membranes and gas adjustment devices are sequentially mounted on each of the air inlets and the return air inlets; the gas adjustment devices comprise motor devices, gas adjustment membranes and physical absorption devices; the motor devices retain nitrogen and exhaust oxygen actively and passively; sterilization deodorization devices and space electric field devices are mounted on the corresponding refrigeratorcompartments; and the sterilization deodorization devices comprise UV-irradiation devices, photocatalytic generation devices, ion generation devices and water ion generation devices. Different refrigerator compartments are arranged to store different foods, so that food tainting and cross contamination are avoided; and the gas adjustment devices and a breathable and moisture-proof membranes are mounted on each of the air inlets and the return air inlets, and the sterilization deodorization devices and the space electric field devices are arranged, so that the environment and the sterilizing and fresh-keeping effects in a refrigerator are ensured.

Description

technical field [0001] The invention belongs to the technical field of refrigerator freshness preservation, and in particular relates to a refrigerator freshness preservation device based on gas regulation. Background technique [0002] The fresh-keeping factors that affect the storage of cooked food include temperature, humidity, gas, wind circulation, microorganisms, etc. Appropriate temperature can inhibit the growth of microorganisms during the preservation of cooked food and maintain the flavor of food; appropriate humidity is an important factor to maintain the sensory color and quality of cooked food; appropriate gas regulation can inhibit the growth and reproduction of microorganisms and maintain the original color and luster of food Flavor; wind circulation can accelerate water volatilization and affect the quality of food. [0003] With the acceleration of the pace of life, when cooking is too troublesome, some people will buy some cooked food and eat it directly ...
