Multifunctional tobacco leaf stack sealing storage method capable of adjusting storage environment

Abstract

The invention relates to a tobacco leaf stack sealing storage method capable of adjusting storage environment, comprising the following steps: 1) building a tobacco leaf stack sealing space capable of adjusting storage environment: covering the warehoused tobacco leaf stack using a plastic seal tent and enclosing the tobacco leaf stack in the sealed space; the sealed space enclosed by the plastic seal tent is perform air flow commutation with the outside when an air input control joint and an air output control joint are turned on and the sealed space enclosed by the plastic seal tent is at full sealed state when the air input control joint and the air output control joint are turned off; 2) gassing to disinfect; 3) filtering and purifying the steamed and disinfected noxious gas; 4) performing the daily tobacco-leaf mould proof conservation; 5) in winter, starting the plastic seal tent to perform the winder general investigation and natural ventilation and conservation of the tobacco leaf and restoring the plastic seal tent until the next early spring. The sealing storage method has low cost and environmental protection.

Description

technical field [0001] The invention relates to a sealed storage method for stacking tobacco leaves. Background technique [0002] Before the tobacco leaves are used for production and processing, the natural alcoholization of the tobacco leaves must be completed through a storage period of 2 to 3 years, so as to improve the smoking quality of the 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. At present, most domestic tobacco leaves are stored in warehouses. The warehouses with good conditions have good airtightness and are equipped with air conditioners or dehumidifiers. Others are basically conventional natural storage methods. Two rounds of fumigation with phosphine are required every year. To kill insects, the poisonous gas generated after fumigation is naturally ...

AI Technical Summary

Problems solved by technology

[0003] ①As the climate continues to warm, the safe storage of tobacco leaves depends 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. This kind of equipment also needs to have the ability to prevent the corrosion and pollution of fumigation pesticides

[0004] ② The scale and area of ​​tobacco leaf warehouses are generally large. Due to the frequent transfer of tobacco leaves into and out of the warehouse, it is easy to be infected by imported insect pests. It is difficult to find a suitable time to fumigate and kill insects with chemical agents. As a result, tobacco leaves are often seriously infected with insects.

And because of the lack of effective protection means, the tobacco leaves will be infected with insect pests again after a chemical fumigation and control. It is often necessary to repeat the fumigation and control 2 to 3 times in a year, which is expensive and unsafe.

[0005] ③At present, most of them are fumigated in the whole warehouse, which will produce more toxic gases and make it difficult to effectively discharge them in an environmentally friendly manner.

[0006] ④In the current daily storage and maintenance system for storing tobacco leaves, warehouses with good conditions are equipped with dehumidifiers or air-conditioning equipment, and dehumidification and cooling are carried out every spring and summer. However, this maintenance mode requires warehouses to have good heat preservation and moisturizing conditions. , whenever there are personnel and logistics in and out of the warehouse, the formed low-temperature and dry storage environment will be destroyed, and the maintenance equipment needs to be turned on repeatedly, which greatly increases energy consumption and storage maintenance costs.

[0007] ⑤ During the storage of tobacco leaves, technical links such as daily maintenance, isolation and pest control, fumigation and desinsection, ventilation and dehumidification, drying and mildew prevention, sealing and oxygen reduction and preservation are disconnected from each other, and the functions are difficult to convert

Most of them are repeated investment, several sets of personnel are implemented step by step, lack of connection and transition, which not only wastes a lot of manpower and material resources, but also is not conducive to the safe storage and maintenance management of tobacco leaves
