Embodiment Construction

[0020] The technical solution will be further described below in conjunction with the accompanying drawings as an example.

[0021] This example uses a vertical airflow ascending intensive automatic curing barn. There are 5 tobacco leaf baking racks from bottom to top in the barn. Input the baking data indicated in the curve in the computer of the control system, place a PT100 with a resolution of 0.1°C and a detection accuracy of 0.25% in the baking room as a temperature sensor, connect the temperature and humidity data collected by the sensor to the control computer, and ignite That's it. The specific operation is as follows:

[0022] 1. Yellowing period

[0023] (1) Raise the dry bulb temperature to 30°C at a rate of 1°C / h, keep the temperature constant for 7±0.4-0.7 hours, and wait for the tip of the tobacco leaves on the first tobacco leaf drying rack to turn yellow to 60%;

[0024] (2) Raise the dry bulb temperature from 30°C to 35°C at a speed of 1°C / h, and keep the ...

Abstract

The invention discloses a high-quality tobacco leaf baking process. Major aims to be fulfilled at every time interval of tobacco leaf baking are classified into a yellowing stage, a wilting stage, a color fixing and leaf drying stage and a stalk drying stage, a more intuitional baking process curve is drawn, and a temperature raising speed, upper and lower limit temperature values, a humidity range to be controlled, heat preserving time, and quality appearance forms including color luster, dryness shape and percentage in all tobacco leaves to be achieved in tobacco leaf baking are set at every stage. At the yellowing stage, the leaf surfaces of tobacco leaves on first and second tobacco leaf baking frames in a baking room become yellow completely; at the wilting stage, all tobacco leaves in a furnace wilt and become yellow; at the color fixing and leaf drying stage, tobacco leaves on a bottom tobacco leaf baking frame become pointed, leaves are drum-shaped or approximately drum-shaped, and the leaf surfaces are dry; and at the stalk drying stage, heat is preserved till all tobacco stalks in the furnace are dried completely. According to the baked tobacco leaves, the green smoke rate and ash hanging rate can be reduced remarkably, and green stalks, clear sheets, green flotation, ash hanging and the like are reduced.

Description

technical field [0001] The invention relates to a high-quality tobacco leaf baking process. Background technique [0002] In the production of tobacco leaves, varieties and cultivation are the foundation, and baking is the key. In recent years, my country's tobacco leaf curing process has undergone various reforms. For example: two-stage baking process, multi-stage baking process, ordinary baking room baking process, three-stage baking process, etc., under specific economic basic conditions, combined with specific types of baking rooms, resulting in different Content, different forms of baking process. [0003] At present, most of the existing barns of tobacco farmers in Yunnan Province are characterized by vertical air-flow ascending intensive automatic barns, and the previous three-stage roasting process or ordinary barn roasting process has been adapted to the baking process. There is no requirement to use the barn to bake qualified tobacco leaves. During the curing p...
