Problems solved by technology

The current domestic rebaking industry processing mode is to use high temperature to dry the tobacco leaves until the moisture content of the inflection point of the tobacco leaves is 8-10%, and then cool in the cooling zone, and then carry out moisture upsurge in the moisture resurgence zone, so as to meet the packing requirements. During this process Due to the high baking temperature of tobacco leaves, a large amount of original aroma of tobacco leaves is lost, which reduces the comprehensive use value of tobacco leaves. Therefore, we need to explore a new type of redrying processing technology

Embodiment 1

[0019] Taking Qujing tobacco leaf C3F as an example, in the single-stage leaf redrying processing mode, the temperature of each drying zone is set as follows: the first zone is 65°C, the second zone is 75°C, the third zone is 80°C, and the fourth zone is 70°C. The speed is the same as the conventional speed, the moisture content in the cooling zone is controlled at 10.5-11.5%, and the qualified rate of leaf shrinkage has been significantly improved with the decrease of temperature. Generally, the temperature of tobacco leaves before entering the drying zone is 27-30 ℃, because this invention has regularly and greatly lowered the temperature of the curing barn, the temperature difference when the tobacco leaves enter the curing machine gradually decreases, and at the same time, the temperature difference between the barns in each area also gradually decreases and shrinks, and the sudden temperature rise of the tobacco leaves is alleviated. Under this processing mode, the pass ra...

Embodiment 2

[0021] Taking B2F grade Qujing tobacco leaves as an example, before single-stage re-curing mode processing, the average content of several main chemical components of tobacco is about: nicotine 2.6, reducing sugar 28.05, total sugar 30.2, total nitrogen 2.4, etc. In the stage re-baking processing mode, the temperature of each drying zone is set at 65°C for the first zone, 70°C for the second zone, 75°C for the third zone and 70°C for the fourth zone. The drying rate is controlled between 11.5-12.5%. With the decrease of the temperature in the drying area, its main chemical composition content: nicotine 2.17, reducing sugar 28.94, total sugar 29.7, total nitrogen 1.92, while the reducing sugar is only 25.05 in the traditional baking method , Nicotine is only 1.87, but the total nitrogen is increased by 2.26.

Embodiment 3

[0023] Taking Qujing tobacco leaf C3F as an example, in the single-stage redrying processing mode, the temperature of each drying zone was set at 50°C in the first zone, 90°C in the second zone, 70°C in the third zone and 75°C in the fourth zone, and the moisture content in the cooling zone was controlled at 11 -12%, the chute transports the material at the same speed as in regular use. Compared with the traditional method, the total amount of aroma components in the single-stage method is higher at low temperature, indicating that the redrying temperature has a significant impact on the aroma components of the tobacco leaves, and the low redrying temperature is conducive to the retention of the aroma components in the tobacco leaves. In the process of lowering the temperature, the content of aroma components is effectively retained, so that the lost content of aroma components is reduced. For example, the content of solanone increases and retains 5.27, damascenone increases an...

Abstract

The invention relates to a single-section type leaf redrying processing process, which is characterized in that leaves which are threshed and destemmed are baked in a single stage mode by a redrying machine; encasement process index is achieved after heat preservation balance; and finished product is packed. For effectively ensuring smooth development of the process, a cabinet entering device is arranged behind a discharge belt of a machine tail. The invention can reserve the incense of tobacco to the utmost extent in the redrying link, and enhance the internal quality and the integrated use value of tobacco. The processing process is effectively simplified, original functions of a cooling zone and a reversion zone are abandoned, the processing process is concise, and single-process parameters are designed to be thoroughly concrete. Cabinet entering reworking design is increased at the tail of the redrying machine, the tobacco which does not meet the technical requirements enters the cabinet for newly processing, tobacco screenings caused by manual reworking are reduced, the consumption of water, electricity, gas and steam energy can be effectively reduced, and earth resources areprotected.

Description

technical field [0001] The invention relates to a single-stage leaf redrying process, which belongs to the technical field of tobacco. Background technique [0002] In the development of cigarette raw materials, one is to solve the basic quality and stability of tobacco leaves, the other is to improve the aroma quality of tobacco leaves, and the third is to form rich and diverse local styles and characteristics. Reservation, the rebaking link of the sliced ​​tobacco is particularly critical. The current domestic rebaking industry processing mode is to use high temperature to dry the tobacco leaves until the moisture content of the inflection point of the tobacco leaves is 8-10%, and then after cooling in the cooling zone, the moisture will rise in the moisture resurgence zone, so as to meet the packing requirements. During this process Due to the high baking temperature of tobacco leaves, a large amount of original aroma of tobacco leaves is lost, which reduces the comprehe...
