Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing:

[0023] Such as Figure 1-Figure 4 Shown, a kind of rice fresh-keeping gas comprises nitrogen, odorant, oxygen, carbon dioxide, gaseous water.

[0024] Further, expressed by volume components, the mixing ratio of each component is: 9900-9950 of the nitrogen, 1-2 of the odorant, 1-3 of the oxygen, 80-90 of the carbon dioxide, and 80-90 of the gaseous water 1-5.

[0025] Further, the odorant is gas produced after crushing garlic or ginger.

[0026] A preparation device for rice fresh-keeping gas, comprising a gas mixing tank 14 and an air storage barrel 12, an electronic pressure gauge 8 is arranged on the outer wall of the gas mixing tank 14, and the electronic pressure gauge 8 is electrically connected to a controller 7. The controller 7 is provided with a touch control screen 22, an alarm 21 is provided beside the touch control screen 22, a pressure monitoring probe 28 i...

Abstract

The invention discloses rice preservation gas which comprises nitrogen gas, an odor agent, oxygen gas, carbon dioxide and vaporous water. The gas has a good rice preservation effect, and gas leakage can be found in time. The invention also discloses a preparation device of the rice preservation gas. The preparation device comprises a gas mixing tank and a gas storage barrel, wherein an electronicpressure gauge is arranged on the outer wall of the gas mixing tank, the electronic pressure gauge is electrically connected with a controller, a touch control screen is arranged on the controller, analarm is arranged beside the touch control screen, a pressure monitoring probe is arranged inside the gas mixing tank, an inner sleeve is arranged inside the gas mixing tank, and a stirring shaft isarranged inside the inner sleeve. The device can automatically perform mixed preparation of gas and is simple and convenient to operate. The invention also discloses a preparation method of the rice preservation gas. The nitrogen gas, the odor agent, the oxygen gas, the carbon dioxide and the vaporous water are uniformly mixed together by adopting the preparation method. The gas can be mixed moreuniformly by adopting the method.

Description

technical field [0001] The invention relates to the technical field of modified atmosphere preservation of rice, in particular to a rice preservation gas, a preparation method and a preparation device thereof. Background technique [0002] With the prolongation of storage time, the quality of grain will gradually decline naturally, and the speed of aging depends on different storage methods. Aged rice not only has poor edible quality, but also may contain some harmful toxins such as Aspergillus flavus, which poses a great threat to the health and life of consumers. Now the main storage forms of rice are normal temperature storage, low temperature storage, anoxic (natural anoxic, CO2 filled, N2 filled, vacuum) storage, chemical storage, mechanical refrigeration storage, plastic film airtight storage (rice pile), coating fresh-keeping technology storage etc. Oxygen storage includes natural hypoxia, CO2 filling, N2 filling, vacuum and other hypoxic storage measures. Because ...
