Alcoholization system for improving alcoholization quality of flue-cured tobacco lamina

Abstract

The alcoholization system comprises an alcoholization warehouse, an alcoholization cabinet is arranged in the alcoholization warehouse, an inner cavity of the alcoholization cabinet is divided into multiple layers of placement spaces by multiple layers of supporting plates, a containing frame is arranged in each layer of placement space, each layer of supporting plate comprises an upper partition plate and a lower partition plate which are fixedly connected up and down, and the upper partition plate and the lower partition plate are arranged in the containing frame. A ventilation device is arranged in a ventilation gap between the upper partition plate and the lower partition plate and comprises a ventilation main pipe and a plurality of ventilation branch pipes, air outlet holes are formed in the upper side and the lower side of each ventilation branch pipe respectively, the inlet ends of the ventilation main pipes in the supporting plates are gathered to a connecting pipe, and the inlet end of the connecting pipe is connected into a ventilation cylinder. A heat preservation shed roof is arranged on the top of the alcoholization warehouse, and a gas introduction device for introducing outside air into the gas heating cavity and the ventilation barrel from the gas inlet pipe is arranged in the ventilation barrel. Compared with the prior art, the tobacco alcoholization cabinet has the following advantages that the alcoholization uniformity of all layers of tobacco leaves in the alcoholization cabinet is guaranteed, and the alcoholization quality is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco processing equipment, in particular to an alcoholization system for improving the alcoholization quality of sheet tobacco. Background technique [0002] Alcoholization of tobacco leaves refers to the process in which tobacco leaves are aged under artificial or natural conditions after baking and rebaking, so that a series of (bio)chemical changes occur in the contents of the tobacco leaves, resulting in a more revealing aroma of the tobacco leaves and a significant improvement in smoking quality. Therefore, alcoholization of tobacco leaves is an important process link in cigarette processing and product quality improvement. Alcoholization of tobacco leaves is a micro-anaerobic fermentation and conversion reaction process, in which microorganisms undoubtedly play a central role. In comparison, the higher the grade of tobacco leaves High, the surface microbial species richness is higher during aging...

Problems solved by technology

[0003] However, in the aging method of static storage, since the tobacco material is flat and has a certain thickness and density of the material, it is difficult to make all the tobacco material fully contact with the air by blowing or blowing compressed air. In the alcoholization device provided in the prior art, the hot air used to supplement the temperature and oxygen often enters from the top, bottom or even corner of the alcoholization cabinet. Uniform, and the side of each layer of tobacco material that is exposed to the wind and the side that is not exposed to the wind is also heated unevenly, which will easily lead to a low degree of oxidation after alcoholization and low alcoholization quality
