Embodiment 1

[0047] The carbon dioxide contained in the first component gas tank 171, the oxygen contained in the second component gas tank 172, the carbon monoxide contained in the third component gas tank 173 and the hydrogen contained in the fourth component gas tank 174 are filled one by one Into the vacuum container 120 through the gas supply pipeline 110, in the process of passing the above-mentioned component gases into the vacuum container 120, after a certain component gas is passed into the vacuum container 120, close the intake valve 121 of the vacuum container 120, start The vacuum pump 130 evacuates the air supply pipeline 110, and then opens the valve corresponding to the next component gas tank and the intake valve 121 to feed the next component into the vacuum container 120 until all the gas is passed into the vacuum container 120 , to obtain fresh meat gas. The ratio of carbon dioxide, oxygen, carbon monoxide and hydrogen in the fresh meat fresh-keeping gas is 5×10 4 : 7×...

Embodiment 2

[0049] The carbon dioxide contained in the first component gas tank 171, the oxygen contained in the second component gas tank 172, the carbon monoxide contained in the third component gas tank 173 and the hydrogen contained in the fourth component gas tank 174 are filled one by one Into the vacuum container 120 through the gas supply pipeline 110, in the process of passing the above-mentioned component gases into the vacuum container 120, after a certain component gas is passed into the vacuum container 120, close the intake valve 121 of the vacuum container 120, start The vacuum pump 130 evacuates the air supply pipeline 110, and then opens the valve corresponding to the next component gas tank and the intake valve 121 to feed the next component into the vacuum container 120 until all the gas is passed into the vacuum container 120 , to obtain fresh meat gas. The ratio of carbon dioxide, oxygen, carbon monoxide and hydrogen in the fresh meat preservation gas is 3×10 4 : 5×1...

Embodiment 3

[0051] The carbon dioxide contained in the first component gas tank 171, the oxygen contained in the second component gas tank 172, the carbon monoxide contained in the third component gas tank 173 and the hydrogen contained in the fourth component gas tank 174 are filled one by one Into the vacuum container 120 through the gas supply pipeline 110, in the process of passing the above-mentioned component gases into the vacuum container 120, after a certain component gas is passed into the vacuum container 120, close the intake valve 121 of the vacuum container 120, start The vacuum pump 130 evacuates the air supply pipeline 110, and then opens the valve corresponding to the next component gas tank and the intake valve 121 to feed the next component into the vacuum container 120 until all the gas is passed into the vacuum container 120 , to obtain fresh meat gas. The ratio of carbon dioxide, oxygen, carbon monoxide and hydrogen in the fresh meat fresh-keeping gas is 42×10 4 : 5...

Abstract

The invention relates to the field of fresh-keeping gases, and provides a fresh meat fresh-keeping gas. The fresh meat fresh-keeping gas comprises carbon dioxide, oxygen, carbon monoxide and hydrogen, wherein the volume ratio of the carbon dioxide to the oxygen to the carbon monoxide to the hydrogen is (3*10<4> to 5*10<4>):(5*10<4> to 7*10<4>):(5-10):(6-8). The fresh meat fresh-keeping gas has good fresh-keeping effect on fresh meat. The invention further provides a preparation method of the fresh meat fresh-keeping gas for preparing the fresh meat fresh-keeping gas. The preparation method is simple. The invention further provides a preparation device of the fresh meat fresh-keeping gas for preparing the fresh meat fresh-keeping gas. The preparation device comprises a gas pipeline, a vacuum container, a vacuum pump and a first pressure gage, wherein the first pressure gage is communicated with the vacuum container; the vacuum container is provided with an air inlet valve and communicated with the gas pipeline; and the vacuum pump is communicated with the gas pipeline. The preparation device is simple and easy to operate, and the obtained fresh-keeping gas is high in accuracy.

Description

technical field [0001] The invention relates to the field of fresh-keeping gas, in particular to a fresh-keeping gas for fresh meat, a preparation method and a configuration device thereof. Background technique [0002] With the improvement of people's living standards, consumers pay more and more attention to food quality and food safety, especially fresh pork, which is in great demand and difficult to preserve, its freshness and shelf life have become factors that affect consumers' purchases. preferred factor. Manufacturers and supermarkets also take great pains to keep the meat as delicious as possible and extend the shelf life, and they are looking for a package that is convenient for storage, non-toxic, harmless, long-lasting, and easy to transport. The modified atmosphere fresh-keeping mixed gas of fresh pork invented by us can solve these problems. Therefore, the modified atmosphere fresh-keeping technology of fresh pork has great application and promotion prospects...
