Method for mechanically humidifying and moisturizing warehoused tobacco leaves in dry and cold season

Abstract

The invention relates to a method for mechanically humidifying and moisturizing warehoused tobacco leaves in a dry and cold season. The method is characterized by comprising the following steps of: 1) constructing a plastic tent sealing system capable of mechanically adjusting and controlling an internal warehouse environment of a tobacco leaf stack in a tobacco warehouse; and 2) after finishing the step 1) of constructing the plastic tent sealing system capable of mechanically adjusting and controlling the internal warehouse environment of the tobacco leaf stack in the tobacco warehouse, setting a temperature and humidity adjusting and controlling combination in the tobacco warehouse at temperature of between 10 and 25 DEG C in the warehouse environment and relative humidity of between 55 and 70%in the tobacco leaf stack in the dry and cold season in which the temperature of the atmosphere environment is lower than 10 DEG C, wherein the step 2) is realized by adopting any one of the following three methods. The method has the characteristic of simplicity and the characteristic that the warehoused tobacco leaves can get through the winter in dry and cold places.

Description

technical field [0001] The invention relates to a method for mechanically regulating humidity and moistening stored tobacco leaves in dry and cold seasons. Background technique [0002] Tobacco leaves harvested in the same year must be stored and aged for more than one year before they can be used. Because there are different degrees of defects in the quality of new tobacco, such as the lack of aroma, strong irritation, heavy green miscellaneous gas, prominent endemic miscellaneous gas, rough smoke, etc., the tobacco must be naturally mellowed or fermented to enhance the aroma of tobacco leaves. Appears, eliminates green miscellaneous gas, reduces irritation, improves aftertaste and flammability of tobacco leaves, so as to meet the requirements of the cigarette industry. [0003] The purpose of natural aging of tobacco leaves is to overcome the bad quality of new cigarettes, improve and enhance the internal quality and appearance quality of tobacco leaves, so as to make it ...

AI Technical Summary

Problems solved by technology

[0015] In order to solve a series of technical problems in the storage and maintenance of tobacco leaves, the inventor has applied for a utility model patent in 2009 - "Tobacco Leaf Stacking Sealed Tent" (Patent No. ZL2009 2 0086679.5), although this patent provides a tobacco leaf stacking Sealing method, but did not further describe the method of mechanical humidity control of tobacco leaves; the inventor applied for an invention patent in 2009 - "Multifunctional Tobacco Leaf Stacking Sealed Storage Method with Controllable Storage Environment" (Patent No. ZL2009 1 0062727.1), Although this patent provides a storage and maintenance technology system for storing tobacco leaves, relying on this patented technology still cannot solve the problem of condensation and icing on the inner surface of the tent that tends to occur when artificially humidifying sealed tobacco leaf stacks under low temperature conditions , the moisture inside the stack of tobacco leaves can still be transferred by humidity and heat, resulting in the loss of moisture in the tobacco leaves; in 2011, the inventor applied for an invention patent - "A Method for Mechanically Regulating and Artificially Filling Tobacco Leaves with Nitrogen", this patented technology mainly It provides a set of green and environmentally friendly technical methods for preventing insects and mildew, but it is less involved in the issue of tobacco leaf humidity control under low-temperature dry conditions, and does not propose a set of mechanical moisture control for tobacco leaf stacks under low-temperature dry conditions. Control Index System of Leaf Operation Technology

[0016] In the actual production work of the tobacco storage industry, there have been mechanical artificial heating and heating of the tobacco leaf warehouse in winter, and then artificial humidification in the tobacco leaf warehouse to maintain the humidity in the tobacco leaf stack, but the resulting The high-humidity environment is easily destroyed by the continuous flow of people and goods in and out of the tobacco warehouse, and the energy consumption of the warehouse is quite serious

[0017] To sum up, in the current production practice and existing patented technologies, there is basically no one that can fully meet the requirements of tobacco leaf stacking sealing, mechanical adjustment of humidity and leaf maintenance and quality improvement systems for the hot and humid southern regions and the dry and cold northern regions. The construction and operation methods are mainly manifested in the fact that the existing storage technology has no environmental control measures to inhibit the moisture and heat transfer of tobacco leaf stacks, and has not constructed a sealing method that is beneficial to the humidity adjustment and moisturizing of tobacco leaf stacks, and there is no one that is conducive to Tobacco leaf stacking humidity maintenance measures, there is no combination of temperature and humidity control indicators suitable for storing tobacco leaves in dry and cold areas for safe wintering, and the existing temperature and humidity control measures for tobacco warehouses consume high energy consumption and cause serious waste
