Cured tobacco baking technique capable of improving quality and flavoring

Abstract

The invention relates to a quality-improving, flavouring, roasting technique of tobacco leaves, belonging to the technical field of roasting tobacco technique. The key technology lies in that: (1) adjusting humidity at a low temperature until turning yellow, roasting the tobacco leaves on the base frame of a roasting room until stems turn green and leaves turn yellow, with the temperature in a furnace less than 39 DEG C, the temperature of a wet bulb less than 35 DEG C and the relative humidity between 92% and 75%; (2) stabilizing the temperatures and discharging moisture until the leaves wilt, roasting until all the tobacco leaves in the furnace fully wilt and diachyma is 7.5-8.5 dried, with the temperature in the furnace between 40 DEG C and 48 DEG C, and the relative humidity in the furnace between 67% and 38%; (3) ventilating and dehydrating until the leaves are dry, roasting until the tobacco leaves on the base frame roll a lot and the upper leaves are 7.5-8.5 dried and roll a little, with the temperature in the furnace between 49 DEG C and 53 DEG C, and the relative humidity in the furnace between 42% and 31%; (4) controlling temperature and humidity until the stems are dry,roasting until all the tobacco leaves in the furnace are dry, with the temperature in the furnace between 54 DEG C and 68 DEG C, and the relative humidity in the furnace between 29% and 12%. The invention has advantages of a simple operation, safety, stable yellow tobacco leaves keeping property, good wrinkling degree of leaves, increased oil, and greatly increased fragrance of leaves; and is applied to roasting tobacco leaves in different ecological environments.

Description

A flue-cured tobacco curing process that can improve the quality and flavor of tobacco leaves Technical field: The invention relates to a flue-cured tobacco curing process capable of improving the quality and flavor of tobacco leaves, and belongs to the technical field of flue-cured tobacco preparation technology. Background technique: In the production of flue-cured tobacco, varieties and cultivation are the foundation, and baking is the key. Curing is a key link that determines the quality of tobacco leaves, and it is also a weak link in China's tobacco production, and a bottleneck that restricts the further development of China's tobacco production. Due to the reasons of improper baking process and wrong operation method, the quality of tobacco leaf curing and the situation of roasting bad tobacco leaves can be seen everywhere. According to the survey, tobacco farmers usually lose between 20% and 30% during the roasting process. People in the smoking area generally re...
