Embodiment Construction
[0020] The present invention will be further described below in conjunction with accompanying drawing.
[0021] Such as figure 1 As shown, the large yellow croaker automatic controlled atmosphere fresh-keeping device of the present invention comprises a box body 1 and a box cover 2, a plurality of one-way valves 3 are arranged on the box body 1, and a plurality of gas slow-release bags 4 are arranged on the inside of the box body 1, each The gas slow-release bag 4 is connected to the one-way valve 3 correspondingly. The gas slow-release bag 4 is made of a microporous film, and each one-way valve 3 on the outside of the box body 1 is provided with a gas tank 5. The device 6 respectively pressurizes the gas tank 5 so that the gas in the gas tank 5 enters the gas slow-release bag 4 through the one-way valve 3, and the gas detection probe 7 is arranged in the box body 1, and the gas detection probe 7 is used to detect the gas inside the box body. In a controlled atmosphere enviro...

The invention discloses an automatic modified atmosphere packaging device of a large yellow croaker. The automatic modified atmosphere packaging device comprises a box body (1) and a box cover (2), wherein a plurality of one-way valves (3) are arranged on the box body (1), a plurality of gas slow release bags (4) are arranged on the inner side of the box body (1), the gas slow release bags (4) are correspondingly connected with the one-way valves (3), and a gas tank (5) is arranged on each one-way valve (3) of the outside of the box body (1). The automatic modified atmosphere packaging device of the large yellow croaker also comprises a pressurizing device (6) for pressurizing the gas tank (5) to enable gas in the gas tank (5) to enter into the gas slow release bag (4) through the one-way valves (3). The invention also discloses an automatic modified atmosphere packaging method of the large yellow croaker. The automatic modified atmosphere packaging device and method of the large yellow croaker are capable of maintaining a modified atmosphere environment for a long time, bring convenience for transportation, and are suitable for modified atmosphere preservation of rarity fishes such as the large yellow croaker.
Description
technical field [0001] The invention relates to an automatic controlled atmosphere fresh-keeping device, in particular to an automatic controlled-atmosphere fresh-keeping device and a fresh-keeping method for large yellow croaker. Background technique [0002] Modified atmosphere fresh-keeping is a fresh-keeping technology developed in the early 1950s, using different concentrations of mixed gas (CO 2 , N 2 , O 2 ) to replace the air in the packaging, thereby weakening the breathing intensity of fresh products, inhibiting the growth and reproduction of microorganisms, reducing the speed of chemical reactions in food, preventing the oxidation and deterioration of nutrients, so as to achieve the purpose of extending the preservation period and improving the preservation effect. However, the modified atmosphere preservation of large yellow croaker has relatively high requirements on equipment, so it is not popular in China. [0003] The existing modified atmosphere fresh-ke...
