Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method of harvesting and roasting to prevent the base of tobacco leaves from mildew and rot during roasting. By controlling the methods of harvesting, loading and roasting tobacco leaves, it effectively solves the problem of easy yellowing during the roasting process. The problem of mildew at the base of tobacco leaves is especially suitable for the middle and lower leaves of flue-cured tobacco with high moisture content

Embodiment 1

[0027] For Yunyan 87 in a production place in Hubei Province, the tobacco leaves in the lower second shed are loaded on conventional hanging rods, and the method of harvesting and roasting of the present invention is adopted, and the following specific operations are carried out in the air-flow ascending intensive curing barn:

[0028] (1) Tobacco leaves are harvested after 10 am on sunny days, and the tobacco leaves show no dew when harvested.

[0029] (2) Use 1.35m tobacco rods to weave cigarettes, each rod weaves 90-110 pieces of tobacco, and holds 420 rods.

[0030] (3) After loading the tobacco, the temperature was raised to 38°C at a heating rate of 0.5 / h, the wet bulb temperature was controlled at 35°C, and the temperature was stabilized for 13 hours. The tip of the high-temperature layer tobacco leaves turned yellow.

[0031] (4) When the tip of the high-temperature layer tobacco leaves turns yellow, the temperature is raised to 40°C at a rate of 1°C / h, the wet bulb te...

Embodiment 2

[0035] The comparative test of embodiment 2 conventional method of collecting and roasting and method of collecting and roasting described in the present invention

[0036] Test object: the central tobacco leaves of Yunyan 87 from a certain producing area in Hubei Province.

[0037] Conventional harvesting and roasting method (T1): pick tobacco in the morning, weave 120-130 pieces of tobacco per rod, and use a three-stage baking process (the existing conventional process) for baking. The heating rate of h is raised to 38°C, the wet bulb temperature is controlled at 36-37°C, and the temperature is stabilized until the tobacco leaves in the high temperature layer turn yellow by 6-7%, and the temperature is raised to 42°C at a heating rate of 1-2°C / h. Control the temperature at 36-37°C, stabilize the temperature until the tobacco leaves are 8-9% yellow, raise the temperature to 46-48°C at a heating rate of 0.5-1°C / h, control the wet bulb temperature at 37-38°C, and stabilize th...

Abstract

The invention relates to a picking and curing method for preventing rotten tobacco base parts in the curing process. The method is used for preventing tobacco base part rotting in the curing yellowish-turning process of lower middle part tobaccos of flue-cured tobaccos with higher water content. The method comprises the steps that the tobaccos are collected after 10 on the mornings of sunny days,the tobaccos are cured in a bulk curing barn after the tobaccos are wadded, the time, humidity and the like of the stage of low-temperature yellowish turning of the bulk curing barn are strictly controlled when curing is conducted to reduce the generation of rotten tobaccos, and the curing quality of the tobaccos is improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco harvesting and preparation, and in particular relates to a picking and roasting method for preventing leaf bases from mildew and rot during tobacco leaf roasting. Background technique [0002] The middle and lower leaves of flue-cured tobacco that grow mature in rainy seasons, due to low dry matter content and high moisture content, are prone to mildew at the base of the leaves during tobacco leaf curing, which affects the quality of tobacco leaves and seriously affects the income of tobacco farmers. [0003] In the prior art, there is no relevant research on the harvesting of this type of tobacco, and the traditional three-stage baking method ("turning yellow, fixing color, and drying gluten") cannot meet the needs of baking. Therefore, it is necessary to focus on the moisture content The middle and lower tobacco leaves of the higher flue-cured tobacco provide a suitable curing scheme....
