Embodiment 1

[0033] The leggy tobacco leaf curing method is used for the curing of leggy tobacco leaves. Leggy tobacco leaves refer to tobacco leaves with hypertrophy, thick tendons and stalks, and less dry matter accumulation caused by factors such as excessive nitrogen fertilizer application, tobacco plant nutritional imbalance, and inadequate field management.

[0034] 1. Harvesting standard of leggy tobacco leaves

[0035] When harvesting leggy tobacco leaves, you should wait patiently for them to mature and turn yellow, so as to prevent yellowing and dehydration difficulties during baking. But it should not be overcooked to prevent ashes or blackened. It should be harvested when the tip of the leaf is obviously yellow, the leaf surface is yellow, and it is eight to nine mature.

[0036] 2. Requirements for weaving poles of leggy tobacco leaves

[0037] It is necessary to classify the rods to ensure that the same rods are of the same quality. Based on a 1.5-meter-long standard rod, ...

Abstract

The invention discloses a roasting method for leggy tobacco leaves, which is used for roasting leggy tobacco leaves. Two tobacco leaves are arranged on the pole as a pinch, and each pinch of tobacco leaves is arranged back-to-back; then it is dried in three stages and six steps. When harvesting leggy tobacco leaves, you should wait patiently for them to mature and turn yellow, so as to prevent yellowing and dehydration difficulties during baking. But it should not be overcooked to prevent ash or blackening. According to a standard rod of 1.5 meters long, each rod is woven with 45 to 55 pinch of tobacco, that is, 90 to 110 pieces of tobacco per rod. Compared with the traditional method for curing leggy tobacco leaves, the method for curing leggy tobacco leaves of the present invention increases the proportion of high-quality tobacco by more than 11%, the proportion of middle and high-grade tobacco by about 6%, and the proportion of variegated tobacco is reduced by more than 11%. Nearly 30%, the proportion of hanging ash is reduced by nearly 40%, the proportion of flue-cured black tobacco is reduced by more than 16%, and the proportion of flue-cured green tobacco is reduced by more than 20%.

Description

technical field [0001] The invention belongs to the field of tobacco leaf curing, and relates to a curing method for leggy tobacco leaves. Background technique [0002] After the tobacco leaves are woven into the roasting room, they mainly go through five processes of low temperature humidity adjustment and yellowing, temperature stabilization and dehumidification after ripening, ventilation and dehydration to dry the leaves, and temperature control and humidity control to dry the tendons. Each process has different requirements for temperature and humidity. Grasping the temperature and humidity control at each stage is the key to ensuring the quality of tobacco leaf curing. [0003] Different tobacco leaves have different requirements for the curing process of tobacco leaves. The applicant has developed different curing processes for tobacco leaves with different qualities: including the curing process of high temperature and drought under-ripe tobacco leaves, the curing pr...
