Embodiment 1

[0031] Embodiment 1 is filled with nitrogen separately

[0032] Lay a protective cushion layer on the ground, lay a composite film bottom cover on the protective cushion layer, stack the stored goods grain rice on the composite film bottom cover, lay a top film on the top of the stack of stored goods, and then cover the composite film top cover, use a plastic sealing machine to heat seal the bottom cover of the composite film and the top cover of the composite film together, and reserve a hole, connect the exhaust fan to the reserved hole to extract the gas in the stack, make the composite film close to the stored items, A small hole is opened on the opposite side of the reserved hole of the membrane, and an oxygen detector is connected, and nitrogen gas with a volume concentration of 95% is charged from the reserved hole. When the oxygen concentration measured by the oxygen detector reaches 5%, the nitrogen gas filling is stopped. The heat sealing laminator seals all the open...

Embodiment 2

[0034] Embodiment 2 is filled with nitrogen separately

[0035] Lay a protective cushion on the ground, lay a composite film bottom cover on the protective cushion, stack the stored items tea Tieguanyin on the composite film bottom cover, lay a top film on the top of the stack of stored items, and then cover the composite film For the top cover, use a plastic sealing machine to heat seal the bottom cover of the composite film and the top cover of the composite film, and reserve a hole, connect the exhaust fan to the reserved hole to extract the gas in the stack, so that the composite film is close to the stored items. A small hole is opened on the opposite side of the reserved hole of the composite membrane, and an oxygen detector is connected. Nitrogen gas with a volume concentration of 98% is charged from the reserved hole. When the oxygen concentration measured by the oxygen detector reaches 3%, the nitrogen gas is stopped. Seal all the openings with a heat-sealing plastic ...

Abstract

The invention discloses an air-conditioning storage method, which comprises the following steps of: a, laying a protection pad layer on the ground; b, laying a composite membrane bottom sleeve on the protection pad layer; c, stacking the stored objects on the composite membrane bottom sleeve; d, laying a top membrane on the top of the stored object stack, and then covering a composite membrane top cover; e, thermally sealing the composite membrane bottom sleeve and the composite membrane top cover together by using a plastic envelope machine, and reserving a hole; f, connecting an exhaust fan at the reserved hole in the step e to exhaust the gas in the stack so as to make the composite membrane attach the stored objects; g, forming a small hole on the opposite side of the reserved hole of the composite membrane, and connecting a gas detector; h, filling nitrogen and/or carbon dioxide into the reserved hole in the step e, and stopping filling when the concentration of the gas measured by the gas detector reaches the preset concentration; and i, sealing all the holes by using a thermal plastic envelope machine, and finishing the storage. The air-conditioning storage method can rapidly kill various insects in the stored objects, suppress mold growth, and guarantee the quality of the stored objects.

Description

technical field [0001] The invention relates to a storage method, in particular to a controlled atmosphere storage method. Background technique [0002] my country is a large agricultural country, and the production and storage of tobacco, grain, Chinese herbal medicine, tea, ramie, vegetables, and fruits play a decisive role in people's lives. [0003] my country purchases nearly 80 million tons of tobacco leaves every year. After the tobacco leaves are harvested and baked, in order to remove the green miscellaneous taste of the tobacco leaves, reduce irritation, change the aroma, and taste quality, etc., reconcile the chemical components, improve the flammability and taste quality of the tobacco leaves, and flue-cured tobacco It must be stored and alcoholized before it can be used in cigarettes. Generally, tobacco leaves need to be stored and aged naturally for 1-3 years before they can be used for cigarette production. However, because tobacco leaves are rich in nutrient...
