Burley tobacco processing method

Abstract

The invention provides a burley tobacco processing method capable of effectively improving tobacco shred quality. The method comprises the following steps: carrying out constant-speed drying on tobacco shreds; after the burley tobacco shreds are dried at a constant speed for a certain period of time, reducing the temperature of hot process air, keeping the preset humidity of the hot process air, and performing first-stage decelerated drying on the tobacco shreds; and after decelerating and drying for a period of time, reducing the humidity of the hot process air, and carrying out second-stagedecelerating and drying on the tobacco shreds. According to the invention, during drying of cut tobaccos, deceleration drying is divided into two stages. In the first deceleration drying stage, only the temperature of hot process air is reduced and the humidity is not reduced, so that the situation that the cut tobacco is dry due to simultaneous humidity reduction in the temperature reduction process can be avoided, and in the second deceleration drying stage, the humidity of the hot process air is reduced, the temperature is already reduced, and the humidity of the hot process air is changedto avoid a large amount of dry tobacco.

Description

technical field [0001] The invention relates to the field of tobacco production, in particular to a method for processing Burley tobacco. Background technique [0002] Burley tobacco belongs to the safflower species, which originated in Ohio, USA. It is the raw material of mixed cigarettes and can also be used in cigars, pipe tobacco and chewing tobacco. Burley tobacco has thick main veins, high moisture content, thin and light leaves, loose but not rough tissue structure, strong elasticity, high filling value, and good flavor absorption performance. Mainly used as a raw material for blended cigarettes, it can also be used in cigars, pipe tobacco and chewing tobacco. The main vein of Burley tobacco is thicker, the moisture content is higher, the leaves are thin and light, the tissue structure is loose but not rough, the elasticity is strong, the filling value is high, the performance of absorbing spices is good, the content of nicotine and total nitrogen is higher than that...

AI Technical Summary

Problems solved by technology

Therefore, the most important thing in the high-temperature roasting of Burley tobacco is the constant-speed drying stage, and the subsequent stage is often not paid much attention to, especially when the roasting temperature is high, it is easy to appear dry ends in many cases, which affects the quality of shredded tobacco.
