Problems solved by technology

This method has at least the following four defects: first, there are huge potential safety hazards. If aluminum phosphide meets open water, it will react violently and burn, and in severe cases, it will cause an explosion; second, it is a highly toxic substance, which can easily cause personnel poisoning. pollution and other issues; third, it has strong metal corrosion, which is easy to cause corrosion of storage equipment and various probes; fourth, the resistance of pests has been increasing over the years, resulting in incomplete insecticide and difficult to kill insect eggs, etc.
When the oxygen is connected to the outside air by cutting the cut or opening the oxygen regulating valve, the remaining atmosphere regulator in the ash stack will react with the oxygen in the outside air entering the ash stack again. On the one hand, it causes The resource waste of the atmosphere regulator, on the one hand, after the atmosphere regulator reacts with oxygen and generates heat, additional water vapor w

Embodiment 1

[0038] (1) Clean the bottom of the stack, lay the cushion material, and lay PE-PA composite film (barrier film bottom film) and low-density polyethylene film (LDPE, moisture-proof and breathable film bottom film) successively according to the size of the stack, PE-PA composite film The thickness of the film is 8 filaments, the thickness of the low-density polyethylene film is 5 filaments, and the oxygen transmission rate is 5000mL / 24h·m 2 0.1Mpa;

[0039] (2) Lamina tobacco leaf stacking, carry out tobacco leaf stacking according to conventional stacking mode;

[0040] (3) Spread the atmosphere control agent evenly around the bottom and the top of the smoke stack quickly, the amount of the atmosphere control agent is 1.2kg / m 3 ;

[0041] (4) The top cover made of the moisture-proof and breathable film and the top cover made of the barrier film are respectively covered on the cigarette stack in sequence, and the bottom film made of the moisture-proof and breathable film is he...

Abstract

The invention provides a flue-cured tobacco lamina modified atmosphere storage method convenient for later oxygen regulation, and relates to the technical field of tobacco mellowing storage. The method comprises the following steps of putting an atmosphere regulating agents around the bottom and on the top surface of a tobacco lamina stack, wherein the putting amount of the atmosphere regulating agents is 1.2-1.5 kg/m < 3 >; respectively covering a moisture-proof breathable film and a barrier film on the surface of the tobacco stack in which the atmosphere regulating agents are put according to a sequence, and sealing; and when the oxygen concentration of the tobacco stack needs to be increased again, introducing the dry sterile air into the tobacco stack, and when the oxygen concentrationin the tobacco stack is increased to a target range value, stopping inflation, and releasing the sealing state of the barrier film. The method provided by the invention can effectively avoid the problems that the atmosphere regulating agent resources are wasted, the dew formation is generated during the oxygen regulation operation of the tobacco stack, the external insect sources, mould and moisture easily enter the tobacco stack to influence the tobacco leaf quality, the oxygen regulation operation consumes manpower, the efficiency is low and the operation quality cannot be guaranteed, and realizes the rapid, safe, stable and efficient tobacco stack oxygen regulation operation links.

Description

technical field [0001] The invention relates to the technical field of tobacco aging storage, in particular to a modified atmosphere storage method for sheet tobacco which facilitates later oxygen adjustment. Background technique [0002] Tobacco is one of the important economic crops in our country and an important processing raw material for the cigarette industry, with huge economic value. After the tobacco leaves are harvested and baked, generally in order to remove the green miscellaneous gas of the tobacco leaves and reduce the irritation of the taste, improve the aroma quality of the taste, and reconcile the chemical components inside the tobacco leaves, it takes about 2 years in the natural environment (certain Oxygen concentration and temperature and humidity conditions) storage alcoholization time. According to incomplete statistics, about 80 million tons (1 load=50kg) of flue-cured tobacco leaves need to be stored in my country every year. [0003] However, beca...
