Mould-proof and insect-proof tobacco leaf storage method

Abstract

The invention, which belongs to the technical field of tobacco leaf storage, discloses a mould-proof and insect-proof tobacco leaf storage method. The method comprises the following steps: (1), isolating and cleaning a tobacco leaf raw material storage warehouse, and sealing doors, windows, floor windows, floor drains, floor seams and expansion joints in the warehouse; (2),stacking tobacco leavesnormatively, sealing the tobacco stacks through insect-proof composite films to form a sealed curtain, and carrying out fumigating and insect killing on the sealed tobacco stacks; (3), isolating the fumigated sealed tobacco stacks, and putting tobacco insect lures and tobacco leaf protective agents into the sealed tobacco stacks; and (4),carrying out insect pest situation monitoring on a storage bin and stacks of the tobacco leaf raw materials, and carrying out irradiation treatment on the sealed tobacco stacks regularly; and when an insect condition exceeds the standard, carrying out insect pest controlling between the storage bins. With the method, the fumigating times of the tobacco leaves in the storage period can be reduced, the risk and potential safety hazard of insect prevention work are greatly reduced, insect pests of the tobacco leaves are prevented, tobacco leaf mildewing and oxidative deterioration are inhibited and eliminated, and the tobacco leaf alcoholization quality in the sealed storage period is improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf storage, and relates to a mildew-proof and insect-proof storage method for tobacco leaves. Background technique [0002] Tobacco is hygroscopic. Putting tobacco in air with a certain temperature and humidity can absorb moisture from the air or emit moisture into the air. The storage of tobacco leaves is an important link in the cigarette production and processing process. A good storage environment plays an important role in the stability of the quality of cigarette process raw materials and the maintenance of the quality and style of cigarette products. [0003] During the storage process of tobacco leaves, it is easy to breed tobacco pests and produce mildew, which will bring harm to the stored tobacco leaves, and the quality of the tobacco leaves will reach the best after 1-2 years of natural aging period. If they continue to be stored and cannot be put into use quickly, the quality of the...

Problems solved by technology

However, there are disadvantages such as high risk and unsatisfactory fumigation and insecticidal effect; the technical measures to prevent and control the mildew of stored tobacco leaves mainly include controlling the moisture content of tobacco leaves entering the warehouse, controlling the relative humidity of the warehouse air, spraying chemical agents in the warehouse for disinfection, and improving the packaging conditions of tobacco leaves. Wait

Although these measures have played a certain role in reducing the mildew of tobacco leaves, in actual production, it is difficult to achieve ideal storage environment conditions. Once the mold in tobacco leaves encounters suitable temperature and humidity conditions, mildew will occur in tobacco leaves and quickly spread
