Modulation method for improving tobacco leaf quality of Chinese prepared tobacco raw material of heated cigarettes by utilizing manual control

Abstract

The invention discloses a modulation method for improving the tobacco leaf quality of a Chinese prepared tobacco raw material of heated cigarettes by utilizing manual control. The modulation method comprises the following steps: (1) harvesting fresh tobacco leaves of Chinese prepared tobacco which are properly mature, and hanging on rods; (2) shed loading: loading the tobacco leaves on which the rods are hung into an airing shed; (3) stabilizing the temperature, adjusting the humidity and turning brown: airing until about 90% of the tobacco leaves are brown; (4) adjusting temperature and humidity and shaping: airing the tobacco leaves until the tobacco leaves become soft and strips, and shaping; continuously blending, stopping heating and humidifying when the main veins of the tobacco leaves become brown, are basically dry or are dry and fragile, and naturally softening; (5) unloading the leaves from the rods and bundling; and (6) storing and alcoholizing, namely naturally alcoholizing in a room which is free from peculiar smell, dark, aired in the shade and ventilated. The content of aroma substances in the tobacco leaves and the sensory quality under the heating condition are improved, and the method has great significance in guaranteeing the quality stability of Chinese prepared tobacco raw materials of heated cigarettes.

Description

technical field [0001] The application belongs to the technical field of tobacco modulation, and in particular relates to a modulation method for improving the quality of raw tobacco leaves of heated cigarette native tobacco by utilizing manual control. Background technique [0002] With the acceleration of the global tobacco control movement, the tobacco industry has entered a new period of seeking changes and breakthroughs, promoting and accelerating the research and development and marketization of new tobacco products, mainly heated cigarettes. The core of the competition of heated cigarette products is tobacco raw materials, and the development of tobacco raw materials with diversified flavors will be the development trend of new tobacco products with Chinese characteristics. Tuyan belongs to the type of air-cured tobacco in tobacco. Compared with flue-cured tobacco, it has the characteristics of strong varieties and local attributes, unique aroma quality of tobacco lea...

AI Technical Summary

Problems solved by technology

Tobacco leaves are generally prepared by farmers themselves after harvesting. Different modulation techniques are commonly used, such as half-drying and half-drying, alternating drying and fermentation, full-drying, and full-drying. Unevenness affects the stability and consistency of tobacco leaf raw materials for heated cigarettes

The uncontrollable natural environmental conditions are often unable to fully meet the stringent requirements of traditional modulation methods on moisture, temperature and environmental sanitation during the fermentation process, resulting in many green and yellow pieces of tobacco leaves, poor alcohol taste, heavy unpleasant smell, high sugar content, and heating.
