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: 65℃ in one zone, 75℃ in two zones, 80℃ in three zones and 70℃ in four zones, and the conveying trough conveys materials The speed is the same as the conventional speed. The moisture content of the cooling zone is controlled at 10.5-11.5%, and the eligibility rate of the leaf curling rate has been significantly improved with the decrease of temperature. In general, the temperature of the tobacco leaves before entering the drying zone is 27-30 ℃, because this invention reduces the temperature of the barn on a regular basis, so that the temperature difference when the tobacco leaves enter the barber is gradually reduced. At the same time, the temperature difference between the barns in each area is also gradually reduced. The sudden temperature rise of the tobacco leaves is alleviated. In this processing mode, the qualified rate of b...

Embodiment 2

[0021] Taking Qujing tobacco leaf B2F grade tobacco as an example, before the single-stage redrying mode, the average content of the main chemical components of several tobacco is about: nicotine 2.6, reducing sugar 28.05, total sugar 30.2, total nitrogen 2.4, etc. In the stage rebake processing mode, the temperature of each drying zone is set to 65℃ in the first zone, 70℃ in the second zone, 75℃ in the third zone and 70℃ in the fourth zone. The conveying trough conveys the material at the same speed as the conventional one, and the cooling zone contains water The rate is controlled between 11.5-12.5%. As the temperature of the drying zone decreases, its main chemical content: nicotine 2.17, reducing sugar 28.94, total sugar 29.7, total nitrogen 1.92, while the reducing sugar is only 25.05 under the traditional baking method. , Nicotine is only 1.87, but total nitrogen increases 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 is set at 50℃ in the first zone, 90℃ in the second zone, 70℃ in the third zone and 75℃ in the fourth zone, and the moisture content of the cooling zone is controlled at 11 -12%, the conveying trough conveys the material at the same speed as the conventional one. Compared with the traditional method, the single-stage method shows that the total amount of aroma components is higher at low temperature, indicating that the redrying temperature has a significant effect on the aroma components of tobacco leaves. A low redrying temperature is beneficial to the retention of aroma components in tobacco leaves. In the process of lowering the temperature, the content of fragrance components was effectively retained, reducing the content of lost fragrance components. For example, the content of solanone increased and retained 5.27, the increase of damascone ...

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 blade redrying processing technology, which belongs to the technical field of tobacco. Background technique [0002] The development of cigarette raw materials is to solve the basic quality of tobacco leaves to be qualified and stable, the second is to improve the aroma quality of the tobacco leaves, and the third is to form a rich and diverse local style and characteristics. Therefore, can the tobacco aroma be maximized during the processing process Preservation, the redrying of sliced ​​tobacco is particularly critical. At present, the processing mode of the domestic redrying industry is to use high temperature to dry the tobacco leaves to the inflection point of the tobacco leaf with a moisture content of 8-10%, and then after cooling in the cooling zone, the moisture rises in the moisture regain zone to meet the packing requirements. Tobacco leaves are too high in curing temperature, which causes a large loss of ...
