Embodiment 1

[0022] The tobacco stems are packed into 5 cigarette packs according to the specifications of 40cm×60cm×85cm with a baler, each cigarette pack weighs 60Kg, and the total weight of the 5 cigarette packs is 300Kg, and put into the gas-phase double-dynamic tobacco alcoholization fermentation tank; Pass through purified compressed air to make the pressure in the tank reach 0.10Mpa (enhance the oxygen supply in the tobacco pack), maintain it for 50 minutes, and then exhaust the pressure to release the pressure in the tank to 0.5Mpa suddenly (exclude the heat in the tobacco pack) and CO 2 , fluffy tobacco bag at the same time), maintain 60min; Carry out periodic pressurization and pressure relief process to the cigarette bag in fermenter jar according to the above-mentioned conditions of pressure filling and pressure relief, and its periodic pulsation time is 1min, like this, in the tank fermentation temperature Tobacco alcoholization of the present embodiment is completed by fermen...

Embodiment 2

[0024] Pack the air-dried shredded tobacco and tobacco stem mixture into 5 cigarette packs according to the specifications of 80cm×100cm×120cm, each cigarette pack weighs 50Kg, and the total weight of 5 cigarette packs is 250Kg, and put them into the gas-phase dual-dynamic tobacco alcoholization fermentation tank ; Introduce purified compressed air into the tank to make the pressure in the tank reach 0.20Mpa (enhance the oxygen supply in the tobacco pack), keep it for 30min, then exhaust the pressure and release the pressure, so that the pressure in the tank is suddenly reduced to 0.2Mpa (to get rid of the tobacco pack). Heat and CO in pack 2 , fluffy tobacco bag at the same time), maintain 40min; Carry out periodic pressurization and pressure relief process to the tobacco bag in fermenter tank according to the above-mentioned conditions of pressure filling and pressure relief, and its cycle pulsation time is 100min, like this, in the tank fermentation temperature 36° C., humi...

Embodiment 3

[0026]Pack the air-dried shredded tobacco and tobacco stem mixture into 4 cigarette bales according to the specifications of 100cm×120cm×160cm, each of which weighs 70Kg, and the total weight of 4 cigarette bales is 280Kg. In the fermenter; feed purified compressed air into the tank to make the pressure inside the tank reach 0.25Mpa (strengthen the oxygen supply in the tobacco pack), keep it for 1min, and then exhaust the pressure to release the pressure in the tank to 0Mpa suddenly ( Remove heat and CO from tobacco packs 2 , fluffy tobacco bag at the same time), maintain 1min; Carry out periodic pressurization and pressure relief process to the cigarette bag in fermenter jar according to the above-mentioned conditions of pressure filling and pressure relief, and its cycle pulsation time is 120min, like this, in the tank fermentation temperature Tobacco alcoholization in this embodiment is completed after fermentation for about 20 days at a temperature of 46° C. and a humidity...

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...
