Problems solved by technology

Tobacco leaves treated by this method can only be verified after a long-term aging cycle, which is a long cycle, and the quality of tobacco leaves is affected by complex mitigation factors in the aging process
[0004] Although the above-mentioned methods can improve the quality of tobacco leaves to a certain extent, the improvement of tobacco leaf quality is not significant, and it is difficult to meet the raw material supply demand of industrialized cigarette production under the condition of tight demand for cigarette production.

Embodiment 1

[0022] The tobacco leaf processing capacity of module A is 8000kg. Vacuum dampening is carried out after preparing materials according to the formula. The raw materials are evenly fed according to the raw material formula, and the tobacco sheets are loosened as much as possible. The leaves are moistened once until the moisture content of the tobacco leaves is 15.0%. Tobacco leaves directly enter the leaf storage cabinet, and the tobacco leaves in the leaf storage cabinet are sent out for secondary re-baking. The temperature of the second re-baking drying zone is 70°C, the temperature of the first zone is 63°C, the temperature of the third zone is 65°C, and the temperature of the fourth zone is 62°C. Set at 6000kg / h, the outlet moisture of tobacco leaves is 11.6%.

[0023] After the second re-baking, the miscellaneous gas of the A module tobacco leaves is reduced, and the comfort is improved. It is compatible with a certain three types of cigarettes, and does not affect the styl...

Embodiment 2

[0025] The tobacco leaf processing capacity of module A is 8000kg. Vacuum dampening is carried out after the raw material is prepared according to the formula. Tobacco leaves directly enter the leaf storage cabinet, and the tobacco leaves in the leaf storage cabinet are sent out for secondary rebaking. The temperature of the second rebaking and drying zone is 75°C, the temperature of the first zone is 65°C, the temperature of the third zone is 69°C, and the temperature of the fourth zone is 65°C. 6000kg / h is set, and the moisture content of tobacco leaves is 11.5%.

[0026] After the second rebaking, the miscellaneous gas of the A module tobacco leaves is significantly reduced, and the smoke fragrance is slightly weakened. It is used in compatibility with a certain four types of cigarettes, without affecting the style, smoke, smoke, and miscellaneous gas of the brand of cigarettes. Under conditions such as stimulation, it is advisable to add the ratio not higher than 15%.

Embodiment 3

[0028] The tobacco leaf processing capacity of module B is 8000kg. Vacuum dampening is carried out after preparing materials according to the formula. The raw material formula is evenly fed, and the tobacco sheets are loosened as much as possible. The tobacco leaves directly enter the leaf storage cabinet, and the tobacco leaves in the leaf storage cabinet are sent out for secondary re-baking. The temperature of the second re-baking drying zone is 78°C, the temperature of the first zone is 68°C, the temperature of the third zone is 69°C, and the temperature of the fourth zone is 65°C. Box moisture 11.5%.

[0029] After the second re-baking, the mixed gas of the B-module tobacco leaves is reduced, the stimulation is weakened, the aftertaste is clean, and the oral residue is reduced. It is compatible with a certain four types of cigarettes, without affecting the style, smoke, and aroma of the cigarettes of this brand. Under the conditions of miscellaneous gas and irritation, it ...

Abstract

The invention provides an industrial method for improving applicability of senior tobacco leaves through module group secondary rebaking. Senior stock tobacco leaves are subjected to function module grouping, grouping adopts a Schmuck value as a main reference condition, the tobacco leaves with a Schmuck value of 2.8-3.6 are A module Schmuck tobacco leaves with high applicability, the tobacco leaves with a Schmuck value of 2.3-2.8 are B module Schmuck tobacco leaves with medium applicability, and the tobacco leaves with a Schmuck value of 2.3 or below are C module Schmuck tobacco leaves with low applicability; through the grouped function modules, the tobacco leaves are subjected to feed preparation according to a tobacco leaf formula, and are sent to a leaf storage cabinet through vacuum wetting and primary conditioning till the leaf water content is 15%-18% and through secondary conditioning till the leaf water content is 17%-20%, the tobacco leaves in the leaf storage cabinet are subjected top leaf secondary rebaking, a second area temperature key in rebaking is controlled at 70-88 DEG C, temperatures in a first area, a third area and a fourth area are matched and adjusted according to the temperature in the second area, rebaking is completed, and the tobacco leaves are packed in boxes for standby use. According to the industrial method for improving the applicability of the senior tobacco leaves through module group secondary rebaking, the senior stock tobacco leaves can be massively utilized, the stock and the raw material cost are saved, and the tobacco quality is not lowered when the method is applied to a tobacco formula.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and mainly relates to the technical fields of threshing and redrying and tobacco leaf treatment. Background technique [0002] In recent years, most of the cigarette enterprises across the country have faced the problems of increasing inventory of inferior tobacco, long inventory of tobacco leaves, and many types and large quantities. The microbial metabolism of long-aged stock tobacco leaves leads to the loss of dry matter and aroma substances of tobacco leaves, and the quality drops sharply with the increase of storage time, making it difficult for these tobacco leaves to be used in the formulation of middle and high-end cigarette leaves, and only in the formulation of low-grade cigarettes Low-grade cigarettes are low in profit and sales are small, and they cannot rely on low-grade cigarettes to consume a large amount of long-aged tobacco leaves in stock, resulting in huge tobacco in...
