Second, the process is different.

1, China process: In the process of silk-making, the raw material of "China" tobacco leaves is not humidified and humidified on the vacuum moisture regain machine, but humidified on the steamer after opening the cigarette case to improve the softness of tobacco leaves; After the stalks are manually removed on the tobacco cutter, the stalks are degraded and used in other cigarette products (stalks are not used in "China" tobacco).

Extended data:

The original formula of "Zhonghua" cigarette used a relatively large proportion of American tobacco leaves, which were old cigarettes imported in the past. At that time (when New China was founded), it was no longer possible to import American tobacco, so the stock gradually decreased. How to continue production has become the most important and urgent problem at present.

Obviously, the only way out is to replace imported tobacco with domestic tobacco. Therefore, the flavor characteristics of various imported tobacco leaves were further studied and compared with local tobacco leaves.

Through proper blending of these tobacco leaves, combined with technical measures such as tobacco leaf selection, stem removal and artificial fermentation treatment, the number of tobacco leaves in the United States has gradually decreased. At one time, the production of "Zhonghua brand" cigarettes from domestic tobacco leaves was realized, and the problem of raw material supply was solved.
