Method for Destemming and Redrying Processing of Turkish Semi-oriental Tobacco Leaf

Abstract

The invention discloses a method for stalk removal and redrying of Turkey half-aromatic tobacco leaf; the method orderly includes moistening twice, one-grade beating, five-grade suspension separation, two-grade beating, three-grade suspension separation, three-grade beating, and second-grade suspension separation; the acquired tobacco stalk is roasted, and the tobacco leaf acquired by suspension separation is roasted. Through the three-grade beating and ten-grade suspension separations, the tobacco material directly enters a redrying device; the tobacco material flow, moistening leaf temperature and temperature in the drying zone are accurately controlled, thus the raw material is uniform in moisture regain and free from high partial moisture; under the low moistening leaf and redrying temperature control, the characteristic aroma of the Turkey half-aromatic tobacco can be better remained. The percent of large and middle size strips of tobacco leaf after beating leaf and redrying is 82.96-83.32 %, the tobacco stalk is effectively removed; the stalk content in the leaf is about 2.28%; the method ensures that the tobacco leaf has high effective filamentation rate in the cigarette manufacturing, reduce the stalk silver, and is good for preparing the tobacco product; the water content of strips is about 12.0%, the rate of mouldy strips is reduced; the method is good for the long-term storage of raw materials.

Description

technical field [0001] The invention relates to the technical field of processing Turkish semi-oriental tobacco leaves, in particular to a method for destemming and redrying processing of Turkish semi-oriental tobacco leaves. Background technique [0002] Tobacco leaves contain a thick central stalk called the midrib. Extending outward from the midrib are smaller stalks called veins, which give structural support to the leaf. Tobacco leaves become leaves after the midrib is removed. Tobacco stems are more porous than leaves and hold moisture more closely, so they should be dried at a different rate than leaves. The texture of the two is also significantly different, and the process is different. Therefore, tobacco leaves must be desiccated shortly after purchase. Stem, so that the tobacco leaves are properly dried before mildew, and it is also convenient for cigarette processing. [0003] At present, the manufacturer is to moisten the Turkish semi-oriental tobacco leaves ...

AI Technical Summary

Problems solved by technology

However, using the existing threshing and re-baking process to treat Turkish semi-oriental tobacco, the percentage of large and medium sheets of tobacco leaves after threshing and re-baking is low, and the stem content rate in leaves is high, and the aroma characteristics of Turkish semi-oriental tobacco are greatly lost.
