Excessive-growing tobacco leaf curing method

Abstract

The invention discloses an excessive-growing tobacco leaf curing method used for curing excessive-growing tobacco leaves, wherein the method comprises the steps: harvesting the excessive-growing tobacco leaves when leaf tips are obviously yellowed, leaf surfaces have yellow spots and the leaves are 80-90% mature; weaving rods in a classified manner to ensure homogeneity of the rods; taking two pieces of tobacco leaves as a pinch, weaving on each rod, and enabling each pinch of tobacco leaves to be woven in a back-to-back mode; and then drying in a three-section six-step manner. The excessive-growing tobacco leaves need be patience in ripening and yellowing, and yellowing and dehydration difficulty during curing are prevented. However, the tobacco leaves cannot be over-cooked, so that ash hanging or curing black is prevented. According to a standard rod with the length of 1.5 m, 45-55 pinches of tobacco leaves are woven on each rod, namely 90-110 pieces of tobacco leaves are woven on each rod, and the pinches of tobacco leaves are back-to-back, so that moisture removal of the tobacco leaves is facilitated. Compared with a traditional tobacco leaf curing method for curing tobacco leaves, the excessive-growing tobacco leaf curing method has the advantages that the first-class tobacco proportion of the excessive-growing tobacco flue-cured tobacco is increased by 11% or above, the middle-first-class tobacco proportion is increased by about 6%, the mixed-color tobacco proportion is reduced by about 30%, the ash hanging proportion is reduced by about 40%, the black tobacco curingproportion is reduced by 16% or above, and the green tobacco curing proportion is reduced by 20% or above.

Description

Technical field [0001] The invention belongs to the field of tobacco leaf roasting, and relates to a roasting method of elongated tobacco leaves. Background technique [0002] After entering the curing barn, the tobacco stalks mainly go through five processes: low temperature and humidity adjustment, yellowing after temperature stabilization and dehumidification, ventilation and dehydration of dried leaves, temperature control and humidity control and dry tendons. Each process has different requirements for temperature and humidity. Therefore, be serious Grasping the temperature and humidity control at each stage is the key to ensuring the quality of tobacco leaves. [0003] Different tobacco leaves have different requirements for the tobacco leaf baking process. The applicant has developed different baking processes for different qualities of tobacco leaves: including the baking process of high-temperature and arid under-ripe tobacco, the baking process of high-temperature and ari...

AI Technical Summary

Problems solved by technology

[0008] 1. It is not easy to bake the elongated tobacco leaves after harvesting; it is difficult to turn yellow and dehydrate during the curing of elongated tobacco leaves.

[0009] 2. Elongated tobacco leaves are easy to roast green and black, and the tobacco leaves are extremely thin after roasting
