Baking technology effectively avoiding phenomenon that dust is hung on tobacco leaves at upper portion

Abstract

The invention provides a baking technology effectively avoiding the phenomenon that dust is hung on tobacco leaves at the upper portion. A tobacco stem tobacco weaving mode is adopted, and according to the tobacco leaf change state in the baking process, the baking process is divided into 9 stages: the stage when leaves become 70-80% yellow and leaf tips and leaf edges become soft, the stage whenthe leaves become 90% yellow and the tobacco leaves at the middle temperature layer start to hook the tips and curl the edges, the stage when yellow leaves have green tendons and the tobacco leaves atthe middle temperature layer reach small dug cylinders, the stage when branch veins of the tobacco leaves are totally yellow and the leaves at the middle temperature layer are 2 / 3 dried, the stage when the yellow leaves have yellow tendons and the leaves are totally dried, the stage when the tobacco tendons state to be dried, the stage when bases of the tobacco tendons become brown and tobacco tendons are shrunk and become brown, the stage when the leaves are 2 / 3 or above dried, and the stage when the tobacco tendons are totally dried. 9 key temperatures and precise humidity control points are mainly set, the time and speed change of the temperatures and the humidity is precisely controlled, the phenomenon that due to imbalance of the time and temperature change of the tobacco leaves, thedust is hung on the tobacco leaves at the upper portion, and the baking quality of the tobacco leaves is improved.

Description

technical field [0001] The invention is a baking process that effectively solves the phenomenon of hanging ash on the upper tobacco leaves, and belongs to the field of baking technology. Background technique [0002] In the process of flue-cured tobacco production, curing is an important link that determines the quality of tobacco leaves, and it is also the weakest link in my country's tobacco leaf production, which directly affects the sustainable development of tobacco leaf production in China. Affected by the special climate conditions in the northern tobacco areas this year, it is generally difficult to bake the upper tobacco leaves, and it is easy to hang ash after roasting, resulting in stiff tobacco leaves and low industrial availability, which seriously restricts the availability of the upper tobacco leaves. According to statistics, the loss rate of tobacco leaves hanging ash due to improper baking of the upper tobacco leaves accounts for more than 30%, which has a h...

Problems solved by technology

Affected by the special climate conditions in the northern tobacco area this year, it is generally difficult to bake the upper tobacco leaves, and it is easy to hang ash after roasting, resulting in stiff tobacco leaves and low industrial availability, which seriously restricts the availability of the upper tobacco leaves.

According to statistics, the loss rate of tobacco leaves with ash caused by improper baking of upper tobacco leaves accounts for more than 30%, which has a huge impact on tobacco leaf quality and tobacco farmers' income

In terms of curing process, the three-stage curing process is still widely used at present. When encountering tobacco leaves with special quality, especially when the upper tobacco leaves show that the leaves are too late or green and late ripening, the operator's technical experience is required to be high, and the operability is poor. , the operation process is highly random and poor in standardization. It is believed that there are many operational errors, especially the current curing process for solving the phenomenon of ash hanging on the upper tobacco leaves is mostly empirical qualitative description, and there are few precise process indicators, so it is difficult to fully demonstrate the advantages of tobacco leaf quality.
