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 until the tip of the tobacco leaf on the first tobacco leaf drying rack turns 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 high-quality tobacco leaf baking process divides the tobacco leaf baking into four stages according to the main purpose of baking at each time period: yellowing period, withering period, fixed color dry leaf period, and dry tendon period, and makes a more intuitive tobacco leaf drying process. Roasting process curve, each stage sets the heating rate and upper and lower limit temperature values, sets the humidity range to be controlled, constant temperature time, and the external quality shape of the tobacco leaves, including color, dryness shape and the proportion of the total tobacco leaves. percent value. For example, during the yellowing period, the tobacco leaves on the first and second tobacco leaf baking racks in the barn are all yellow; during the withering period, the tobacco leaves in the whole furnace wither and turn yellow; The tip is pointed, the leaves form a roll shape or close to a roll shape, and the leaf surface is dry; during the drying period, the temperature is kept constant until the whole furnace is completely dry. The cured tobacco leaves can significantly reduce the rate of blue smoke and ash, and reduce the rate of blue veins, clear flakes, floating green, and ash.

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...
