Gas-phase double-dynamic tobacco alcoholization fermentation method

Abstract

The gas-phase double-dynamic alcoholization fermentation method of tobacco is characterized by that it can make the tobacco raw material placed in fermentation tank implement fermentation under the following conditions; introducing compressed air into fermentation tank and making periodic pulsed pressurization and decompression process, the pressure pressurized into the fermentation tank every time is up to 0.10-0.25 MPa, and retained in 1-50 min., then the pressure is released, and decompressed to 0.0-0.5 Mpa, and retained in 1-60 min., and the periodic pulsed circulation time from pressurization to decompression is 1-120 min., its fermentation temp. is 26-46 deg.C, humidity is 80%-95%, and the fermentation time is 20-30 day so as to implement gas-phase double-dynamic fermentation of tobacco alcoholization, and can raise colour and taste of tabacco.

Description

technical field [0001] The invention belongs to the field of tobacco processing, in particular to a gas-phase dual-dynamic tobacco alcoholization and fermentation method. Background technique [0002] Tobacco alcohol fermentation is an important link in the cigarette industry to improve the smoking quality and usability of tobacco. In the process of tobacco alcoholization and fermentation, the main chemical components of tobacco change, the green miscellaneous gas and irritation are greatly reduced, the aroma is revealed, the taste is mellow, and the color is evenly deepened. At present, the natural alcoholization and fermentation of tobacco has a long processing period (1-2 years), a large area occupied by the plant, a large occupation of capital, high production costs, and prone to mildew and insect damage. Now large-scale cigarette factories at home and abroad still use natural alcoholization fermentation technology to process tobacco. Howeve...

Problems solved by technology

[0010] The purpose of the present invention is to overcome the many defects in the above-mentioned tobacco artificial alcoholization and fermentation technology, and propose a gas-phase double-dynamic tobacco alcoholization and fermentation method that utilizes the principle of gas-phase double-dynamics to carry out artificial alcoholization and fermentation of tobacco, which can effectively achieve uniform fermentation of tobacco , which can effectively control the temperature and humidity in the core (stack core), to avoid local mildew and shorten the fermentation cycle;
