Threshing and Redrying Method for Reducing Phenol Release
A technology of threshing, redrying and releasing, which is applied in the preparation of tobacco, application, tobacco and other directions, can solve the problems that have not been paid attention to, and have not seen related patents and literature reports, and can reduce the amount of phenol released and optimize the Effects of process parameters

Embodiment 1
[0017] The tobacco leaf samples produced according to the existing threshing and redrying process parameters were used as blank samples; among them, for the B3F tobacco leaves in a certain place in 2011, the new hot air moistening process was added, and the tobacco leaf samples produced were optimized samples. Tobacco leaf samples were loosened, rehydrated, shredded, and air-dried under the same conditions, and then rolled into cigarette samples. The phenol content in smoke of the samples was detected in Table 1.
[0018] Table 1: Detection results of phenol release in B3F optimized samples and blank samples
[0019]
[0020] It can be seen from Table 1 that under the new treatment process conditions, the phenol release in the tobacco sample smoke produced by B3F is 16.26% lower than that of the blank sample, which has a significant effect of reducing the phenol release.
Embodiment 2
[0022] The tobacco leaf samples produced according to the existing threshing and redrying process parameters were used as blank samples; the B3F tobacco leaves in a certain place in 2011 were combined according to different process parameters and optimized process parameters, and the process parameters of other processes were unchanged. 3 and optimized samples; the tobacco leaf samples of each group were loosened, rehydrated, shredded, and air-dried under the same conditions, and rolled into cigarette samples. The phenol content detection of the samples in the smoke of the samples is shown in Table 2.
[0023] Table 2: The test results of phenol release in the optimized sample and blank sample
[0024]
[0025] It can be seen from Table 2 that in the threshing air separation process, the phenol content in the smoke of the tobacco sample produced by the upper tobacco leaf B3F under the combination of optimized process parameters is 11.03% lower than that of the blank sample, ...
Embodiment 3
[0027] The tobacco leaf samples produced according to the existing threshing and redrying process parameters were used as B3F tobacco leaves in a certain place in 2011 as blank samples; according to the combination of different process parameters and optimized process parameters, and the process parameters of other processes were unchanged, the tobacco leaf samples produced from 1 to 3. Optimized samples: Tobacco leaf samples of each group were loosened and rehydrated under the same conditions, cut into shreds, and dried naturally, and rolled into cigarette samples. The detection of phenol content in the smoke of the samples is shown in Table 3.
[0028] Table 3 The test results of phenol release between the optimized sample and the blank sample in the rebaking process
[0029]
[0030] It can be seen from Table 3 that the content of phenol in the flue gas of the tobacco samples produced under the combination of optimized process parameters in the re-curing process of tobac...
