Method for storing tobacco leaves by way of mechanical regulation and manual nitrogen charging

Abstract

The invention relates to a method for storing tobacco leaves by way of mechanical regulation and manual nitrogen charging. The method is characterized in that the method includes the following steps: (1) constructing a sealed tobacco leaf-stacking space capable of mechanically regulating the storage environment, the six sides of which are sealed; (2) carrying out nitrogen charging-based fumigating control on tobacco worms and mildew for just one time, and adopting any one or the combination of the following two methods for fumigating control and keeping the closed state for more than 7 days in order to destroy the living environment of pests and mildew, so that the pests can be suffocated and the quality of tobacco leaves can be guaranteed: (a) adopting the charging of high-purity nitrogen to carry out fumigating control; (b) adopting the charging of the mixture of nitrogen and carbon dioxide to carry out fumigating control; (3) manually and mechanically removing accumulated heat and accumulated moisture in tobacco leaf stacks. The method has the characteristics of environment-friendliness and tobacco leaf quality protection.

Description

technical field [0001] The invention relates to a method for storing tobacco leaves through mechanical regulation and artificial nitrogen filling. Background technique [0002] Laminar tobacco is currently the main form of tobacco leaf storage in domestic cigarette factories. Before laminar tobacco is used for production and processing, it needs to go through a storage period of 2 to 3 years to complete the natural alcoholization of tobacco leaves to improve the smoking quality of tobacco leaves. Tobacco leaves are extremely vulnerable to insects and mildew during storage, and daily ventilation and cooling, drying and dehumidification, and ensuring the normal alcoholization of tobacco leaves under natural conditions must be solved. Many new problems are faced in actual work: [0003] ①As the climate continues to warm, the safe storage of tobacco sheets relies too much on good warehouse conditions. The current tobacco leaf warehouses generally need to invest a lot of money to...

AI Technical Summary

Problems solved by technology

[0003] ①As the climate continues to warm, the safe storage of tobacco sheets relies too much on good warehouse conditions. The current tobacco leaf warehouses generally need to invest a lot of money to ensure that the warehouse has good airtight performance and moisture-proof performance. Various equipment also need to have the ability to prevent fumigation and insecticide corrosion pollution

[0004] ②The scale and area of ​​the sliced ​​tobacco warehouse are generally large. Because the tobacco leaves are frequently transferred in and out of the warehouse, they are easily infected by imported insect pests. It is difficult to find a suitable time to fumigate and kill insects with chemical agents, resulting in the tobacco leaves often being seriously infected with insects.

However, with continuous technological innovation and continuous improvement in actual work, it was found that the above-mentioned patented technologies have the limitation of only using phosphine for fumigation and insect control, and cannot fully meet the increasing social requirements for safety and environmental protection. Specifically, Defects and deficiencies are manifested in:

[0006] ①Most of the current tobacco leaf warehouse insecticides use phosphine fumigation, and phosphine fumigation will produce more toxic gases, making it difficult to effectively discharge environmentally friendly

[0007] ② The use of phosphine fumigation to prevent pests requires a series of problems such as preventing chemical explosions, poisoning and pollution, etc., which no longer meets the needs of social development
