Problems solved by technology

[0008] In order to solve the above problems, fully consider the influence of oxygen concentration, pest state ratio, temperature and humidity, and adjust the time of hypoxic sealing according to the actual conditions in the sealed ash stack, so as to completely kill all kinds of pests and eggs, and It can prevent the hypoxic airtight time from being too long and excessively reducing tobacco leaf alcoholization speed and reducing the availability of tobacco leaves. The technical solution adopted by the present invention is that the hypoxic method for killing tobacco pests includes the following steps:

Embodiment 1

[0043] In this embodiment, smoke boxes are randomly selected, and opened, turn up 5-10cm thick tobacco leaves in the box, swing slightly in the box as carefully as possible, then take a 300-500g sample as a whole, shake the sample tobacco leaves, and The pests were shaken onto the white paper, and the number of tobacco pests in each stage was counted. Among them, there were 207 tobacco pest eggs, 129 larvae, 84 pupae, and 21 adults. 19.1%, adult 4.7%.

[0044] The storage material tobacco leaves are sealed, and the steps include:

[0045] a) Determine the stacking position of the tobacco leaves, and place the bottom film of the plastic film on the stacking position;

[0046] b) stacking the tobacco leaves on the plastic film bottom film;

[0047] c) cover the cover film of plastic film, to wrap the tobacco leaf of whole stack in the plastic film;

Abstract

The invention provides a method for killing injurious insects of tobaccos under the condition of low oxygen. The method comprises the following steps of: (1) counting the number of the injurious insects of the tobaccos in different insect states in tobaccos, and computing the ratio of spawns, larvae and imagoes; (2) storing the tobaccos in hermetic space to form a hermetic stack, wherein an oxygen concentration tester, a thermometer and a hygrometer are arranged on the hermetic stack; (3) reducing the concentration of oxygen in the hermetic stack to be below 2 percent, and measuring temperature and humidity in the stack of the tobaccos; and (4) sealing the stack of the tobaccos at normal temperature under the condition of normal humidity for 5 to 35 days according to the concentration of the oxygen in the hermetic stack and the insect state ratio of different injurious insects. By the method, various injurious insects of different insect states in the tobaccos can be killed quickly without the influence on the mellowing quality of the tobaccos.

Description

technical field [0001] The invention belongs to the technical field of tobacco storage and relates to a method for killing tobacco pests with low oxygen. Background technique [0002] In the field of tobacco processing, especially the cigarette industry has strict requirements on the quality of tobacco leaf raw materials. After the tobacco leaves are harvested and baked, there are defects of varying degrees, such as heavy miscellaneous gas, rough smoke, smoke aroma covered by miscellaneous gas, and even bitter, spicy, astringent and other shortcomings, so the roasted tobacco leaves should not be directly used for manufacturing Cigarettes must undergo natural aging treatment. Tobacco leaves in the aging period will undergo a series of chemical changes, reducing miscellaneous gas and irritation, increasing aroma, mellow taste and more uniform color. The aging time of tobacco leaves is generally 1-3 years. [0003] Tobacco leaves are prone to insects during the alcoholizatio...
