Example Embodiment

[0033] Example 1: Application of two-stage intensive curing process of flue-cured tobacco Nanjiang No. 3 variety

[0034] In 2014, the central tobacco leaf of Nanjiang No. 3 variety of flue-cured tobacco planted in Fuquan City, Guizhou Province was selected, and the 15cm of the base of the leaves of the post-harvest tobacco was removed, and the tobacco was packed into the curing barn by using loose leaf cuttings, and the two-stage intensive drying of the flue-cured tobacco of the present invention Baking process for baking.

[0035] Yellowing and water loss stage:

[0036] The first step: After the tobacco leaves are put into the curing barn, close the doors, windows and air inlets, raise the dry bulb temperature to 35°C and the wet bulb temperature 34°C at a heating rate of 0.5°C / h, and bake at a steady temperature for 8 hours;

[0037] The second step: Raise the dry bulb temperature to 39°C and the wet bulb temperature to 38°C at a heating rate of 0.5°C / h. Steady temperature baking ...

[0050] Example 2: Application of two-stage intensive curing process for flue-cured tobacco Bina No. 1 variety

[0051] In 2015, the central tobacco leaves of the flue-cured Bina No. 1 variety planted in Fuquan City, Guizhou Province were selected, and the base 10cm, 12cm and 15cm of the leaves of the post-harvest tobacco leaves were removed, and the loose leaf stacking method was used to pack the tobacco into the curing barn, and the flue-cured tobacco of the present invention was used. Two-stage intensive baking process for baking.

[0052] Yellowing and water loss stage:

[0053] Step 1: After the tobacco leaves are loaded into the barn, close the doors, windows and air inlets, and increase the dry bulb temperature to 36°C and the wet bulb temperature to 35°C at a heating rate of 0.5°C / h, and bake at a stable temperature for 6 hours;

[0054] Step 2: Raise the dry bulb temperature to 38°C and the wet bulb temperature to 37°C at a heating rate of 0.5°C / h, and bake at a stable tempera...

[0064] Example 3: Analysis on the necessity of removing 10-15cm from the base of fresh tobacco leaves

[0065] The 10-15cm of the base of the fresh tobacco leaf is removed, which is equivalent to the cutting length of the base of the cured tobacco (the head part) of 10-12cm. Within this length, the base of this part has the following characteristics:

[0066] 1. According to multiple varieties planted in large areas in Guizhou Province, the cut-off analysis shows that the most leaf content reaches 5% and the least leaves less than 1%;

[0067] 2. According to the length of the tobacco leaf, the weight of the cut leaf base accounts for about 15-20% of the weight of the whole tobacco leaf;

[0068] 3. For bar tobacco, the content of debris in the base of the leaf (bar head) is very high, accounting for more than 50% of the total debris in the whole leaf;

[0069] 4. The quality of this part of the tobacco leaf is relatively poor in the whole tobacco leaf. One is because the tobacco leaf a...

Abstract

The invention relates to a two-stage type bulk curing process for flue-cured tobaccos. A two-stage type curing process is adopted and comprises a yellowing stage and a color fixation and drying stage respectively; tobacco leaves are dried by using dry-bulb temperature of a color fixation later period; according to the curing process, 10-15cm of bases of the leaves are needed to be removed and then the tobacco leaves are filled and cured. The two-stage type bulk curing process for the flue-cured tobaccos has the following advantages that (1) the operability of the two-stage type curing process is stronger; (2) the process is more optimized and yellowing and color fixation of the tobacco leaves are facilitated; (3) stems are dried at low temperature, and the energy is saved; (4) the labor is saved and the cost is reduced; (5) the availability of the tobacco leaves is improved. According to the method provided by the invention, inapplicable leaf bases are treated before an agricultural curing link so that physical distribution cost and re-curing link cost are reduced and the availability of the tobacco leaves is more effectively improved.

Description
